WAVEFORM AND FUNCTION

One of the less welcome side-effects of the transition from fluorescent lighting to LED has been the return of flicker as an issue, as many LED drivers operate at lower frequencies or contain lower frequency components.

f you think back as far as the 1983 suicide bombing of the US embassy in Beirut (and, then aged 15, it is one I still recall vividly) it is clear vehicle-ramming terror attacks are, tragically, not a new phenomenon.

But it is fair to say that using cars and lorries as a weapon in their own right to mow down, maim and kill pedestrians in an instant is a relatively new and horrifying evolution. Moreover, whether we’re talking Nice, Stockholm, Paris, Berlin, Westminster Bridge, London Bridge, Charlottesville or, most recently now, Barcelona, it is becoming all-too horribly familiar.

How we as a society combat this sort of terrorism is deeply challenging.

It is, of course, a relatively cheap and easy form of attack to organise and implement (in that all you need is a vehicle), and therefore extremely difficult for security forces to prevent. At the same time, no one wants to turn our city streets into fortified crash barriers.

So new ILP President Alan Jaques’ suggestion in this edition that we consider the role street lighting may be able to play in the ‘war on terror’, in particular the siting and positioning of streetlights, is both intriguing and, I recommend, well worth reading.

Alan is arguing that siting columns towards the front of the footway rather than at the back could help to prevent vehicles from being able to career at length down a pavement or footway.

Such a move would be unlikely to stop a very determined terrorist, or a terrorist in a large HGV. But for a relatively opportunistic attack, such as we saw on Westminster Bridge for example, having a ‘barrier’ of this sort that a terrorist would either need to navigate around or crash through could provide the public with vital extra seconds to get out of the way.

Moreover, because lighting columns are such a familiar part of our street furniture, discreetly relocating them from one side of a pavement to another would be less unsettling for citizens than, say, more concrete (in all senses) crash prevention infrastructure, while still keeping people safer.

It needs to emphasised that all Alan is doing here is, in effect, thinking out loud. As he highlights, there would be a range of significant practical difficulties that would need to be addressed, such as risk and specification, not to mention potential cost and disruption.

But if lighting – an industry that, of course, has protecting people right at its heart – can ‘do its bit’ to help protect the public from terror attacks, then creative and thoughtful ideas such as this are well worth considering and debating.

n Britain, we still operate on a rail infrastructure built predominately in the 19th and early 20th centuries, while trying to introduce 21st century rolling stock to accommodate increasing numbers of the travelling public.

Improving technology, especially around the quality of DOO (driver-only operation) in-cab monitors and train body-side cameras, can only help improve the views that drivers have of the PTI (platform-train interface) and assist in managing the associated risks.

The need for installing and maintaining compliant lighting against the various rail standards is fundamental to helping us achieve and implement this new technology and

ways of working as part of the rail system as a whole.

Without this approach, we will be unable to offer safer boarding and alighting for passengers, improve accessibility for individuals with reduced mobility, provide services for ever larger volumes of passengers and meet more stringent dwell times required by higher frequency of services. And, all this while still trying to drive down the number of PTI incidents across the network!

Since its inception, the railway has seen many advances in technology over the years, as well as improvements to the standards associated with its operation and the reduction in the likelihood and severity of accompanying risks. Changes in systems have led to improved railway safety, and this has been borne out by the falling rates of incidents and accidents across the UK network. Today we are seeing more than 1.5 billion passenger journeys every year, and this continues to increase as more people switch back to rail as their preferred form of travel.

CHALLENGES FROM LED

8

Yet, although new infrastructure and rolling stock has been introduced on to the network, it is only in the last few years that lighting appears to have been catching up.

The advent of LED technology in lighting may have brought about a new age of energy efficiency and brightness in a world once only lit with the orange glow of sodium lamps. But with it has brought new challenges to the rail network and the way in which trains operate in line with the Railway Group Standards (RGS), Technical Specifications for Interoperability (TSIs), Notified National Technical Rules (NNTRs), how they are interpreted and applied.

Whereas once the impact of glare and dazzle from lamps was perhaps limited to a few locations, and relatively easy solutions could be found to mitigate the issue, this is now becoming more regular as lighting upgrade schemes are implemented across the network or infrastructure improvement works take place at stations and depots.

The changes we have seen have been in a variety of forms; whether they are for station platform lighting, siding and depot lighting, canopy lights or signals. Technology has accelerated, and this invariably means standards are left trying to catch up with the improvements.

In turn, this leaves the infrastructure managers and railway operators trying to interpret those rules currently in place and apply the requirements of the stanwww.theilp.org.uk

dards – using these new technologies – in order to comply with them and to continue to operate safely.

Alterations and upgrades to signal heads and route indicators from traditional filament-style lamps to LEDs introduces the increased possibility of platform-end signals washing out in-cab CCTV monitor images used in the dispatch process of trains. The intensity, position, angle and sight-lines of the platform-end signal must all be considered when reviewing the proposed signalling upgrade. This is in order to make an informed decision on the installation, as well as taking into account any other signals in close proximity.

Indeed, in recent rolling stock introductions, the glare from these platform-end signals was one of the single biggest challenges to overcome when testing the incab CCTV monitors used for driver-initiated DOO dispatch and ensure the images of the dispatch ‘corridor’ (of which more in

going forward. In my opinion, this has to involve the train operator at an early stage so as to understand fully the possible impacts from changes.

DIFFERING STANDARDS

a moment) were both clear and sharp.

For us as train operators, PTI still represents the highest risk to passengers for serious injuries. Although we are seeing reductions in PTI incidents occurring, there were still 1,494 for the year 2015 – 2016*.

The significance of the PTI cannot be underestimated in light of (pardon the pun) the continued roll-out of and the need to meet the requirements of driver-initiated DOO dispatch arrangements associated with the new classes of rolling stock.

The necessity for drivers, as well as passengers, to be able clearly to see and be seen in the dispatch corridor in order to dispatch the train safely is of paramount importance. The dispatch corridor, to explain, is the area from the train body side of each coach along the useable length of the platform, the gap between coper edge (or the coping stone that forms the platform edge) and the train, with at least 1,500mm of the platform measured from the plat-

form edge, and the height of the doors.

The design and type of lighting provided varies, not just at locations across the network, but also across platforms at the same location or even along the same platform.

Variations in the types of lights and lighting provided at a location do not always enable the clearest view of the dispatch corridor in all light conditions.

This means that, even in broad daylight, a canopy that is partially covering a platform is not suitably and sufficiently lit to provide a consistently uniform light or lux level.

The degradation of lamps, and therefore the pre-planned maintenance schedules in order to keep lighting lux levels to at least the minimum required standard, hasn’t always been considered an important factor as part of the dispatch arrangements at locations by infrastructure managers.

Any proposed new lighting schemes on platforms must therefore take this into account in the design and maintainability

Over time, refurbishment works and alterations (to stations in particular) have meant lighting design has not necessarily been looked at holistically, so leading to large contrasts in uniformity along the useable platform area. The application of differing standards, as well as changes over time, applied to contrasting manual or DOO dispatch arrangements at the same location present challenges, too, when it comes to operating differing train types along the same piece of the network.

A train is a train, isn’t it? After all, it just goes from A to B and then back again?! Focusing on the DOO dispatch arrangements, these can be undertaken in a variety of ways dependant on the train being operated and the number of coaches.

They include: driver look-back, platform-mounted mirrors, platform monitors, in-cab monitors and body-side cameras and in-cab monitors with platform-mounted cameras. The varying approaches required to dispatch trains usually occurs as new rolling stock has been introduced to the network. Yet, until recently, infrastructure improvements were not necessarily considered alongside these introductions.

The need to enhance capacity for the increasing numbers of passenger journeys, as well as growing public expectation on the level of service provided by train operators, has led to the expansion of running longer trains over an extended period of the day in order to cope with the demands.

Previously, in many cases, extending older trains to increase the capacity on a route and the number of seats meant adding additional coaches to the set or joining two sets together. For example, you want to double capacity? Just connect two three-coach sets together to make a single six-coach train! Simple or so you would think?

But, what about the length of platforms and the existing infrastructure? If this service was DOO dispatched at locations with mirrors, and the driver looks into the mirror to check along the dispatch corridor, you have now doubled the distance they must be able to see clearly along in order to safely dispatch the train.

Now, consider the impact of non-uniform lighting on the driver’s ability clearly to see images in the mirror at night for the extended section of train and continue to www.theilp.org.uk

safely dispatch the service?! Of course, we undertake a train dispatch risk assessment for six coaches, but usually the same lighting is in place as we had for the shorter three-coach service.

For dispatch arrangements that use driver look-back or mirrors, the Railway Group Standard (RGS) GI/RT7016 Issue 5 sets out the requirements under Part 10.

This states that the minimum horizontal and vertical illuminance values at DOO stations using mirrors or driver line of sight only along the usable platform edge area shall not be less than 20 lux at platform level and a minimum of 6 lux measured vertically at a point 1.0m above the platform surface and perpendicular to the platform edge area respectively. Therefore, it is a relatively straightforward measurement to undertake with a light meter, tape measure and measuring wheel.

However, within the same RGS under Part 10, but where CCTV and monitors are used for DOO dispatch, the equipment is required to be suitable for operation at the lower illuminance values, as set out in clauses 10.3.1 and 10.3.2. The camera therefore needs to be aimed such that the screen contrast is not impaired by the glare from luminaires.

Yet (and to complicate things still further) 10.3.1 requires a minimum illuminance of 2 lux measured vertically at a point 1.0m above the platform surface.

However, 10.3.2 indicates a minimum of 6 www.theilp.org.uk

lux measured vertically at a point 1.0m above the platform surface. So, which is it?! What is the most suitable for the method of dispatch at a given location where multiple stock types and lengths are used?

Surely you go for the higher of the two values in this case and maintain that as your minimum?

ROLE OF NIGHT-TESTING

With the Thameslink Programme (the government-sponsored programme transforming north-south travel through

London Bridge) and specifically the Class 700 train introduction on to the national rail network, the way we at Govia proved the DOO CCTV system, the image quality and the ability of the cameras to provide a consistent picture was through extensive night testing at all locations it was being specified to call at.

We were able effectively to demonstrate that in-cab monitor images were suitable and sufficient to provide a quality image even at the lowest of lux levels given in the standard. The software used by the train’s cameras meant that, even in cases of non-uniformity, it was still able to give consistent pictures across the entire length of the dispatch corridor.

But, just because the system was able to work with varying light levels, we as lighting professionals within the railway industry must not be fooled into thinking that the standards for platform lighting have become redundant!

The starting place has to be meeting at least the minimum requirements of the standard and being able to maintain these throughout our operation. Critically, as we move forward with enhancing the network infrastructure, further consideration for any new designs needs to include the operator’s input in order to ensure the proposal meets the needs of the current operation as well as any future changes that may be planned. ¢

Transport, highways and street lighting: PLG01

The connected ‘smart’ lighting revolution means the role and use of CMS is rapidly changing. The ILP’s new PLG01 outlines pitfalls and considerations for lighting professionals in the commissioning, procurement, installation and operation of CMS

By Peter Harrison

A

mongst lighting asset managers, Central Management Systems (CMS) seem to have become mainstream, with many installations now operating all over the UK. The ILP has just published Professional Lighting Guide 01 (PLG01) after a long process of development. This article explains what is in it and why, as a lighting professional, it may be useful to you.

The original concept for PLG01 was simply to offer information and advice to assist those considering the implementation of such CMS. The original brief was to focus on the features, functions and benefits of CMS and have a process for assessing the various systems on offer and the issues that need to be addressed during implementation.

However, such has been the pace of CMS installation that the features, functions and benefits are now reasonably well known by most lighting practitioners. The brief was, therefore, adjusted to focus not just on the functions, features and assessment of CMS, but also to share the experiwww.theilp.org.uk

ences now gained on the implementation, development and operation of CMS. Indeed, much has been learned from the early installations, so this knowledge has been used to offer advice to those that follow.

PLG01 is a vital publication aimed at exterior lighting professionals; asset managers, contractors, professionals and manufacturers. It provides a step-by-step guide, highlighting the potential pitfalls and considerations in the commissioning, procurement, installation and operation of CMS. It will also benefit all those considering installing or changing CMS. The principles described in it are valid for all installations and, although it has been written primarily for the UK exterior lighting market, it could be used anywhere in the world.

It will be of interest to those joining organisations where CMS has been installed, by offering advice on its operation and management. Indeed, it will also be of use to those with existing installations, offering advice on operational procedures by offering advice on operational procedures and on the production of an operational policy.

September 2017 Lighting Journal

Before embarking on a process of evaluation and procurement of a CMS, PLG01 advises that it is crucial a clear vision of how the CMS is to be deployed and utilised is established. There is no ‘one solution fits all’, and each individual operating authority will have different requirements based on their individual equipment needs, system selection, funding opportunity and levels of deployment.

RISK OF ‘PROJECT CREEP’

So, it is essential, therefore, that the key features required of CMS need to be recorded before the procurement starts.

This is to ensure that evaluation of the various systems on offer can be made against the original vision. This simple advice should avoid ‘project creep’, where what is delivered is different to the original concept for which finance for the project would probably have been approved.

The architecture of CMS is described for both airborne and mains-borne systems to give an overview of how the systems work and communicate. The three main system components used in CMS are: •The node •The collector •The central service These often have different names depending on the supplier, and so can be somewhat confusing, especially to those new to CMS. PLG01 lists these main system components and gives examples of the differ-

ent names manufacturers have attributed to them.

CMS sits separate to the lighting asset management system inventory. The lighting asset inventory contains the ‘static’ asset data, such as: •Location •Asset size and materials •Lantern and gear details •Light source wattage • M aintenance details such as lamp change and cleaning, electrical testing, fault repairs and the like The CMS database contains details of the ‘dynamic’ data. This is the operational diary of events that includes: •Switch on and off time and date •Time, date and amount dimming was applied or changed •Other data such as energy consumption and asset status, such as recording when the asset didn’t operate as planned.

The CMS operational data can be massive, albeit in small pieces. But, still, for a reasonably large inventory it can be hundreds of thousands of pieces of information every day. It is vitally important, therefore, that the asset inventory is accurate and kept up-to-date. When alterations, additions or deletions are made, these need to be reflected in the CMS, as well.

The lighting asset inventory database and the CMS database are linked by a www.theilp.org.uk

14 common field. This affords the possibility of producing comprehensive reports on consumption by light source type or burning hours, and so on. The CMS database needs to be able to handle all the operational information of assets so the energy reports and operational statistics can be determined quickly and easily.

INTERNET SECURITY

One of the key issues today for organisations is IT security, with all organisations now having strict security policies, especially in relation to internet security.

PLG01 discusses the various options in relation to where this database sits. Some manufacturers insist on it being on their servers, others offer Cloud storage, and others are more flexible by offering client hosting.

The advantages and disadvantages of these options are discussed but, clearly, when planning CMS implementation, engaging with your IT partner at an early stage is strongly advised to ensure compliance with IT policies.

This will be an important part of the supplier selection process; your IT partner will be able to advise on ways to address the various issues and should, probably, be party to the supplier discussions and demonstrations. It is also important that, whatever www.theilp.org.uk

CMS is chosen, it is compatible and accessible to your meter administrator.

Having installed CMS, PLG01 offers advice on operational procedures. If you think CMS operation is a ‘five-minute job’, then think again. Operational procedures need to be carefully considered well in advance of deployment so clear demarcation lines are established.

In addition, lines of communication need to be determined to avoid task duplication and, as far as possible, errors occurring. For those managing lighting assets, organisational structure can be complex and, at times, confusing regarding who does what. Typically, there are five lighting asset operational stakeholders: •The asset owner (this would typically be the highway authority) •The asset manager (this would be the highway authority asset manager or consulting organisation managing the day-today maintenance operations) •The meter administrator (where energy is purchased from the competitive market) •The asset maintenance organisation (normally the contractor carrying out routine maintenance, fault repairs and emergency attendance) •The asset installation contractor (or the

Each of the operational stakeholders needs to understand what they are expected to do, when they need to do it and how it should be reported. PLG01 advises that an operational policy should be developed in conjunction with the five stakeholders to ensure all understand their role and each understand how their role fits into the bigger, overall picture.

The document contains typical operations, and suggests to whom these should be attributed, which needs to be established before going live. This may incur additional cost particularly if you are in contract and the item coverage does not include these additional duties.

It is important, too, that equipment specifications are updated to ensure new lighting assets installed by others (such as new developments or major road schemes) are compatible with the installed CMS. This specification should also refer to the operational policy so these third-party works can be seamlessly integrated into the main asset management system and CMS database.

Whatever CMS is deployed, there will be ongoing revenue costs. It is important to accommodate these costs over an extended period to understand exactly what the costs will be. The cost of maintaining the CMS infrastructure will depend upon the equipment installed and the configuration. But for medium to large deployments, this is likely to be thousands of pounds.

Communication transmission costs may be another factor to take account of.

Whereas there may be some savings if CMS is hosted by the client, there could be internal costs relating to server maintenance incurred by your IT partner to take into consideration.

As part of the procurement, it is essential to understand exactly what the licensing and maintenance costs include, and the response times if a problem is detected. Finally, training should be included as part of the deployment, not just for the client staff but should also include contracting staff and their operatives.

PLG01 is available through the ILP website, www.theilp.org.uk, at a price of £35 for members and £60 for nonmembers. ¢

Countering terrorism

In recent months, we’ve seen a spate of horrific attacks where terrorists have used speeding vehicles as weapons. Could rethinking how and where streetlights are sited on the footway be one way that lighting professionals could help to protect the public from such attacks?

By Alan Jaques

I

f we look back just 40 years or so, the thought-process regarding the siting of lighting columns was completely different to what is perceived as current best practice.

Up until this time, most local authority lighting engineers positioned their columns towards the front of the footway.

There were many reasons for this, including the fact the original gas lighting had always been installed in this location, and so it had become to be seen as the norm.

Also, the most widely used light source was low pressure sodium and, being a long light source with a prismatic bowl, the optical performance was relatively poor.

Therefore, locating the luminaire directly above the kerb edge resulted in the edge of the road being well lit, plus it didn’t need to throw the lighting as far across the road compared to if it had been installed at the rear of the footway.

There wasn’t a single reason for the change in practice of siting columns at the rear of the footway, rather there were several things which influenced the change.

Locating the columns towards the rear of the footway reduced the number of columns struck be vehicles, thereby reducing the costs of replacing the columns on the revenue budget and increased road safety.

The increased use of smaller lighting www.theilp.org.uk

sources, such as high-pressure sodium, with efficient reflector technology meant that the light was better controlled and could be positioned further back.

Decluttering of the footway, together with the additional requirements of the Disability Discrimination Act (now part of the Equality Act), meant that in some instances the reduction in available footpath width because of columns being installed towards the front meant there wasn’t sufficient width available for a wheelchair or double-width buggy to pass through.

COUNTERING TERRORISM

There are still occasions when columns are routinely located towards the front, such as terraced streets where the properties have no front garden or have cellars; where the width from back edge to back edge is excessive; where there is a verge between the highway and footway and where the street is tree lined. However, these types of situations form quite a small proportion of locations of new and replacement installations.

In recent months, I’ve started to think we may need to reconsider the default option of siting the column at the rear of the footway. The horrific terror-related incidents involving vehicles in London earlier this year, and most recently in Barcelona,

has made me think that street lighting can play an active part in counter-terrorism.

Counter-terrorism tactics in the design of new public realm schemes to prevent vehicles driving into these public areas are fairly well known. Additionally, large bollards are a common sight nowadays outside many transport interchanges, airports and public buildings.

In the case of newly-designed open spaces, these security features are well integrated into the whole design solution so they aren’t generally noticed by the public.

When large robust bollards are installed as the main deterrent, it is extremely obvious to most people what their purpose is. This will comfort some, however for other people it could make them more nervous, since it is a reminder of what could happen, however remote that possibility is.

Moreover, both concealed and obtrusive security measures have two things in common: they are expensive and require substantial foundations to comply with the appropriate requirements.

It is impractical and too expensive for the government and local councils to install the formal security measures anywhere other than in high-profile locations.

However, it is also not unreasonable to assume terrorists will generally look for locations that have significant numbers of

September 2017 Lighting Journal

people, and none of the obvious, formal security features.

PASSIVELY SAFE LIGHTING COLUMNS

The Motor Industry Research Association has carried out many tests to understand and demonstrate to practitioners the damage that can be done to a vehicle and occupants if it hits a lighting column at speed, and much of this research led to the introduction of different categories of passively safe lighting columns. Indeed, there was an interesting presentation on just this topic at June’s Professional Lighting Summit, which is set to be published shortly within Lighting Journal.

Many of us will have seen the damage that can happen to a vehicle when it has hit a standard lighting column, and very few are driveable afterwards.

In locations where, from time to time, there can be relatively high numbers of people, I feel that consideration should be given to siting lighting columns towards the front of the footway.

The types of locations that I’m thinking of are district centres outside of the nucleus of city centres, football grounds, near schools and colleges, and so on. People are used to seeing lighting columns, so wouldn’t be concerned by seeing them being relocated or sited along footways in greater numbers, and they wouldn’t realise they were there to make them safer at all times of the day and not just at night.

Siting columns towards the front of the footway will help to prevent vehicles from driving for long distances along the footway with the sole purpose of causing harm.

Lighting columns may not, of course, completely stop the largest HGVs, but they would certainly slow them down, providing people with additional life-saving seconds to make their escape.

Such lighting columns could be specified to a higher strength to provide higher resistance than normal units, meaning the use of street lighting in this way could become a valuable added protection for the public.

A risk-based approach would, naturally, be required, and decisions recorded on the design risk assessment. However, provided the speed limit of the road doesn’t exceed 30mph, I would suggest there are many locations around the country where our streetlight assets could help save lives in more than just the usual ways in which we know lighting already helps society. ¢ Alan Jaques IEng FILP is President of the Institution of Lighting Professionals as well as practice manager for lighting systems at Atkins www.theilp.org.uk

Lighting designers should not just settle for illuminating a space.

ighting is more than illumination.

I’m going to talk about lighting which is for people. We need light; we need to be able to see. There is a little species of mole which lives underground and it is very happy; it does very well. And it is totally blind; it needs no light at all. So, if it developed like we did and became a bit brainier, then we’d never have had lighting, because we wouldn’t have needed it.

But we, on the other hand, we did develop, and we chose caves. Perhaps the greatest invention we ever had was the control of fire, and we learned how to make fire to give us light and warmth.

Some people argue that the reason we are active for more hours a day than many other animals is because we developed with the fire that we had learnt to control.

We love fire, we love firelight. The people who liked daylight didn’t go out at night and get eaten by bad animals. The people who stayed by the fire stayed warm, were

good in the evening, people will stay here for longer; they will have coffee, have a beer or two; and they won’t get into their cars and drive to another city – which will use way more energy than you putting in new electrical lighting’. And it was a great piece of thinking – I love that.

active for longer, could see for longer, could do things for longer, and they learned to love light and firelight.

Is it a coincidence that often, when the occasion is right, we choose to dine by candlelight? Is there maybe something within us that associates food and cooking and that kind of light? I don’t know, I’ll leave that to you.

So, by becoming attracted to light, and by those of us who possibly survived because of light, we love light. We are all moths; we can’t help it. That’s why we’re here; we love light. And light which is doing more than illumination doesn’t need to cost any more. It’s possible by using direction, and by using clever ways of laying light out to actually deliver more than just illumination.

For example, we did a lighting strategy for the city of Peterborough and we suggested lighting various buildings that were very much part of the Peterborough story; that gave the impression to people of what a wonderful place it is. The sustainability officer for Peterborough called a meeting for all the design team – the engineers, the landscape architects and us – to check that everything was sustainable, and quite right too.

I was slightly dreading that meeting because we were, without a doubt, adding to the energy bill, even if only in a small way.

But we gave our presentation and, at the end of it, the sustainability officer said, ‘I love it’.

I was surprised and delighted. And the reason, he said, was ‘if Peterborough looks

We can attract people’s attention with light by a number of things. The human eye can’t help itself in the number of reactions it responds to. And it responds to brightness; it tends to look at the brightest thing in its field of vision. It responds to contrast; contrasting things are very attractive to the eye. And movement; again it can’t help itself – if the light suddenly changes you will look at it. If I light the chandelier above us, we will look at it.

That is the power of lighting we in this room all have; we can make people look at what we want; we can use lighting to tell stories, we can lead people. We can direct them away from what we don’t want them to look at, too, if we want.

I’d like to tell you a story of a project we did, at York Minster; it’s all about telling the story. The Minster is a fantastic a piece of architecture and when I looked at it I realised it was wrong to get lighting equipment in the way; it did not need any clutter at all.

So, we did the lighting and we achieved bright lighting levels; it’s flexible lighting that shows off the architecture, lighting that allows the users to use the building in a whole range of different ways. But when you arrive and you have to make that crucial decision – ‘am I going to pay my money to go in here, or not?’ – you can’t see any lighting equipment in the view; you just see the architecture.

The aim was to see the Minster in all its glory. You can see a fitting once or twice, for example backwards from behind the choir, and there are a few other little places where you can see lights. But, generally, we tried to hide the lighting completely; to show off the architecture for the benefit of the people.

Interestingly, it didn’t cost any more to do it than it did to light the Minster normally. We analysed the Minster first. Uplighting the ceiling? No problem; plenty of places up high to hide the fittings. The challenge was lighting the pews below so people could see their various activities.

If I wanted to light an area on the ground we could use some traditional downlighting, straight down. And that would work

September 2017 Lighting Journal

very well; people would be able to read their hymn sheets or whatever and take part in the huge range of activities that take place there. But to get light down like that, straight down, means the fittings have to stick out and then become visible, and I felt that was unacceptable.

So, we lit across. We came from high up from the other side. By coming from high and by using very carefully controlled fittings there was no glare at all; we were then able to push the lights back into those openings at high level and keep them out of sight. And that was how we were able to clear the place totally of visible things, and yet still you can get 200 lux on the ground if you want, if you turn the whole thing up, and that’s how we were able to achieve that lighting with no visible fittings.

HIERARCHIES OF LIGHTING

Lighting is also about hierarchies. Part of the message that all of us can give to people is to make them look at what is the most important thing. And in a shop, the most important thing is the merchandise; what might be bought. So, if we make the merchandise the brightest thing, people’s eyes will naturally go to it and they will look at that first. That’s what a shop, such as Durham Cathedral shop, is all about.

If the shop’s in a nice place, you want to celebrate that as well; that should be the next thing in the order of hierarchy; let’s give the ceiling a bit of light, let’s give that amazing architecture a bit of light to show it off. And, finally, of course there must be light to see your way around safely. So, by having that three-stage hierarchy – merchandise, surroundings, and then functionality – then we can get people to do what we want them to do, and to look at what we want. That is the power that we have in this room as lighting creators.

Sometimes, lights are added purely for decoration and to lead people. It’s called walk-this-way lighting. The lighting can be added and be a beacon to make people go where you want. Light can be fun, as well.

People can interact with lighting, and that takes it up another whole step. Blackpool is, of course, famous for its illuminations. We lit a car park (Talbot Road) and we lit it with colour, which is fun. But what makes it into a proper bit of illumination that is suitable for Blackpool is you can text the car park. You can text ‘Blue’ and it turns blue. Then about ten seconds later it goes back to its background state, which is all the colours changing gently. You can text ‘Green’ and the whole thing turns green, again for ten seconds. Or you can

t

Below: making light tell a story in even a relatively mundane space, such as the A11 underpass

text ‘red’ and it will change, and so on.

There is a total of seven colours and if people know about it they can text ‘Surprise’ and then the whole thing goes mad for a few minutes and flashes on and off.

The software is deliberately designed to rule out various nasty words; you can’t text it something nasty and expect it to go funny.

NON-INTUITIVE APPROACHES

Sometimes, we can be non-intuitive with our lighting. When we lit the Wessex Gallery, which is all about the people who built Stonehenge, those people lived outside, they lived in the daylight pretty much. And we wanted to give the feeling that it was the surroundings that were the brightest thing, because that is what it was; they were in daylight all their natural time.

PEOPLE CAN INTERACT WITH LIGHTING, AND THAT TAKES IT UP ANOTHER WHOLE STEP. WE LIT A CAR PARK IN BLACKPOOL WHERE YOU CAN TEXT THE CAR PARK AND THE COLOUR CHANGES. YOU CAN TEXT ‘BLUE’ AND IT TURNS BLUE. THEN ABOUT TEN SECONDS LATER IT GOES BACK TO ITS BACKGROUND STATE, WHICH IS ALL THE COLOURS CHANGING. YOU CAN TEXT ‘GREEN’ AND THE WHOLE THING TURNS GREEN, AGAIN FOR TEN SECONDS. OR ‘RED’ AND SO ON

So we turned the whole thing upside down, and we made the huge super graphics around the outside the brightest thing; and that gave the feeling of being outside, which is like turning a museum upside down. You can still see lots of artefacts but they’re not the brightest thing in the field of vision, and that was an interesting way of getting a whole new idea and message across.

Fittings can be fun, too; fittings can give more of a message. Again, it doesn’t cost huge amounts of money to add a little bit of more message, or more branding or more whatever to the fittings. William Heath Robinson was a great genius of eccentric thinking, and when we had the privilege of lighting his museum we didn’t want to copy his amazing ideas, that would have been wrong, but just to get that feeling of wackiness over was important.

So, we designed pendant fittings that were visible, looked odd. But they still work. They’re completely adjustable; you can shine light wherever you want. You can aim light at the displays, as the displays move; you can change the direction of the lights; you can change the lenses on the lamps to make wider beams or narrower. It is totally flexible, it’s completely practical, but it looks mad! Because that is what the museum is all about.

In another room, we were there to provide basic lighting, and so a random selection of different sized spheres gave the type of illumination that was needed; they give a good working level of light, and they give the feel that this is a wacky place.

TELLING STORIES

Tell the story of the space. Let me tell you about a really boring, slightly aggressive concrete underpass beside a canal – the A11 underpass in London. We were charged with lighting it and the lighting scheme uses an incredibly low number of watts per sq m illumination. But what

makes that place is the water beside. So, let’s tell that story.

There are lights along the outside of the walkway that shine light on to the surface of the water and make reflections. There are reflections over more or less the entire concrete ceiling. We just turned a boring, slightly aggressive walkway into a place full of the story of the water.

Similarly, I was honoured to be asked to light the London Olympic Park. It was supposed to the greenest Olympics ever – and it was – and it came after Beijing, which had almost limitless budgets and money, and we didn’t. So, we used imagination and skill and we used that message of being green.

We put photovoltaics on the lighting columns. They don’t actually power the columns; but they feed energy back into the Grid and they give that message ‘this is a green place’; it is all about saying the message. Similarly, we had to light a huge area around the main arena; and we could have done it with a forest of standard columns.

But we decided to do it with a small number of really tall masts. And these became icons; these were designed to keep the memory of the Olympics alive. They worked to light that whole area.

They cost no more than a forest of standard columns, but they gave the message.

And the message lasted. When you look at the advertising for the Olympic Park, it is keeping that memory.

So, think about the lighting. Keep the lighting out of the way. For example, the lighting in the pedestrian area of Warrington’s retail quarter is hidden away, way up; lighting of the quality of almost interior downlighting.

Edinburgh, too, was really brave in taking on a whole new way of lighting for its fashion gallery within the National Museum of Scotland. They allowed me to light the fantastic collection of fabrics upside down. The aim was to make it look like a fashion runway, like a fashion show. And it’s bright. But they change the costumes regularly, so there is no problem with fading. And what a fantastic way that museum went about showing its amazing collection.

So, we can take illumination, we can add creativity, we can add messages, we can add branding, and we can make the lighting tell whatever we want. Lighting is for people, and that’s what we should be doing. ¢

Emergency lighting for hazardous areas

LED technology has transformed the design and performance of emergency lighting compared with traditional discharge and fluorescent solutions. But specifying still comes down to effectively assessing factors such as duration, output, instant restrike, maintenance and visual aids

mergency lighting is critical to safety in hazardous areas, especially where there is a risk of power failures. While emergency lighting is required for a wide range of different applications, hazardous areas are often located in high-risk environments with unstable power sources, which makes the need for an effective emergency lighting solution even more important.

While non-emergency lighting tends to use mains/AC power (or through a generator if the site is off-grid), emergency lighting is designed to provide light when the primary power source fails. Although there are different methods of how this back-up is supplied, such as through a central battery system or standby generator, the simplest and most common way is to use self-contained emergency luminaires.

These emergency luminaires have their own back-up power source designed to initiate when the primary power source fails.

TYPICAL APPLICATION

Lifeboat systems found on any offshore vessel or jack-up rig are a good example of an offshore application where emergency

lighting is required. As they are used in times of emergency (when the likelihood of power failures is high), having a lifeboat system with an effective emergency lighting solution is essential. It makes evacuation quicker, easier and ultimately safer, and is a critical part of protecting workers.

Imagine evacuating an offshore rig.

There would be a multitude of challenging elements. Now imagine the near-impossibility of doing this in a blackout. This is why emergency lighting is so important.

Aside from offshore applications, safe evacuation is also important for industrial installations. Escape routes must be clearly identified and illuminated to allow safe movements towards and through the exits in emergency scenarios. Specific standards exist to provide guidance on the specification of emergency lighting and every installation should comply with these standards as a minimum.

SPECIFYING EMERGENCY LUMINAIRES

With a better understanding of why emergency lighting is so important, we must consider the criteria and performance

that an emergency luminaire needs to meet in order to be effective.

Most commonly, the performance of a luminaire tends to be judged by its duration (the length of time the luminaire can provide backup illumination) and/or output (the light output it will provide in emergency operation – generally measured as a percentage of its total light output in normal operation). Let’s consider these two factors in more detail, as well as some various other features which can affect an emergency luminaire.

DURATION

Given that emergency luminaires are powered by a battery (a limited power source), they are designed to provide output for a set time until the mains/AC power can be restored or the site can be evacuated. As standards between sites differ, and the emergency duration requirement varies, it is important to consider the capability between different luminaires when specifying emergency lighting.

Essentially, the question is: ‘Will the luminaire provide adequate light output for a long enough period in order to evacuate or to restore power?’. Some applications (such as the lifeboats mentioned earlier) will require maximum lumen output for around 30 minutes so those on site can be evacuated quickly. Other applications will require longer duration. The majority of in-

and vice versa. It is therefore important for an end-user to analyse the requirements of their site to get this balance right, as shown in Figure 1.

OUTPUT

OTHER FACTORS

• Instant restrike – emergency situations tend to arise without any warning, so having an emergency lighting solution capable of instant restrike is important .

• Maintenance – an emergency luminaire will generally require greater levels of inspection and testing than a non-emergency luminaire. Batteries are consumable items and generally need to be replaced every five-to-seven years, depending on how frequently they are used, but also depending on how well they are maintained.

The extent of ongoing inspection and testing will depend on the specification of the battery. It will dictate the level of conditioning which may be required prior to the luminaire being installed and also how often the luminaire and battery should be cycled in normal operation.

Understanding the maintenance demands of a luminaire, and how it differs between technology types, is another important factor to consider.

• Visual aids – While not directly affecting the performance of the fitting, visual aids can make emergency luminaires easier to identify quickly, manage and maintain.

For example, an indicator or status light, usually as part of a self-testing feature, can quickly tell the user the health status of the emergency battery. (Figure 2) Understanding why emergency lighting is required, and the features and performance criteria that go into an effective emergency luminaire, leads us to look at

The amount of light output a luminaire can provide during emergency operation significantly affects the overall lux levels achieved on-site when mains/AC power is lost.

Each application will have a minimum lux level to which they must comply during emergency scenarios. This will be guided by emergency lighting standards (which are a completely separate standard to general area, non-emergency lighting standards).

However, in practice, higher lux levels are often specified to account for any site-specific tasks. The choice and quantity of luminaire affects how easily these lux requirements can be achieved.

Traditionally, the light output of luminaires can drop significantly when switching to emergency mode. In other words, emergency fluorescent luminaires will typically drop to 20% of their light output (at best) under emergency conditions.

This may not be a serious issue for some applications, as minimum lux requirements on emergency mode do tend to be lower than in normal operational mode.

But it may cause an issue if higher lux levels need to be maintained. More luminaires would need to be installed to raise lux levels on emergency. However, a simpler, more cost-effective solution would be to find a luminaire which can offer a greater output on emergency.

Duration and level of output should be considered together; essentially, they are a trade-off, with one aspect directly affecting the other. The higher the light output on emergency, the shorter the duration –

the technology that enables this.

Specifically, we will now look at LED technology and how it has helped to improve the performance and functionality of emergency lighting.

LED VERSUS CONVENTIONAL EMERGENCY LIGHTING

Earlier versions of emergency luminaires used traditional discharge lamps. However, these were very rare because of their size, weight and cost limitations, and generally only used for specialist applications.

Currently they aren’t considered a viable emergency lighting solution.

When fluorescent emergency lighting emerged, it represented a significant development from discharge solutions.

However, LED emergency lighting offers even greater performance advantages.

Figure 3 below outlines some of the advantages and disadvantages of both approach.

While it is relatively easy to find a luminaire that meets the required output and duration on paper, it is important to consider the other factors that affect the luminaire’s performance in real terms. With reliability being imperative to the effectiveness of an emergency luminaire, LED represents a big improvement on fluorescent technology.

THE FUTURE OF EMERGENCY LIGHTING

1) Battery technology The battery is an essential component of any emergency luminaire. So, as battery technology advances it aids the development of new and improved emergency lighting solutions.

The progression from lead acid to Ni-Cd batteries has helped to reduce the size and weight of emergency systems, thanks to their higher energy density. While other batteries technologies with greater energy density than Ni-Cd already exist, such as Ni-MH (Nickel Metal Hydride) or Li-ion (Lithium Ion), other limitations prohibit them from being commonly adopted.

Ni-MH, for example, suffers from a shorter life cycle, while the volatility of Liion leads to concerns over its suitability for use in hazardous areas, as shown in Figure 4.

However, looking at other industries and the efforts being made to improve battery technology, continued developments in this area look encouraging.

The automotive industry, for example, relies on the development of new and improved battery technology to aid the push towards electric vehicles and provide more effective solutions for its customers.

Inevitably, battery technology will progress to combine greater energy density with improved functionality, which will further optimise the design and performance of LED emergency luminaires.

2) Advancement in LEDs While LED technology has allowed emergency lighting solutions to improve, offering better performance and practicality than discharge and fluorescent lighting, LEDs themselves are constantly evolving.

As LEDs become more efficient, the same level of output can be achieved using less power. This will allow smaller batteries to be used, which will further improve the physical design of emergency luminaires. Alternatively, this could mean greater duration can be achieved thanks to reduced consumption and a smaller draw on the battery.

3) ‘Intelligent’ emergency solutions Developments in self-testing luminaires, which automatically cycle batteries and provide health indicators, are starting to make inspection and maintenance quicker and

easier for users by automating the process.

Removing elements of reliance on operator interaction reduces the chances of human error or neglect, which may affect the performance of a luminaire in an emergency scenario.

More and more ‘intelligent’ emergency solutions are starting to emerge, using a microprocessor that is programmed to automatically cycle the batteries – typically every two to three months.

The results of this self-testing are then highlighted using a tri-colour LED indicator, visually notifying the user if everything is working as it should be or of any faults which require further investigation.

SUMMARY

LED technology has had a significant impact on emergency lighting in terms of improving design and performance of the luminaires compared to traditional discharge and fluorescent solutions. Ultimately this improvement increases safety to those who work in areas where emergency lighting is required.

Emergency lighting: understanding the new BS 5266

31

T

he British Standards Institution (BSI) BS 5266 part 1 2016 Emergency Lighting Code of Practice (CoP) is a key standard in the life-safety industry, helping as it does to define best practice in the design, installation and maintenance of emergency lighting to protect the wellbeing of occupants.

The recent update to the CoP will see it aligned with the latest national and European life-safety regulations, ensuring it continues to provide the most comprehensive guidance for building owners on meeting legal requirements.

The update brings with it a raft of changes that construction, built environment and lighting professionals need to be aware of to ensure that new and existing buildings continue to be compliant, and to uphold the safety and wellbeing of occupants. This article intends to look at, and outline, some of the key revisions.

BS 5266 AND THE LAW

Under the latest fire safety legislation in the UK and Europe, BS 5266 is no longer a

By Ian Watts

prescriptive requirement. Buildings’ life-safety systems can be legally compliant without being certified to the standard.

However, compliance to BS 5266 is the easiest way to demonstrate to auditing authorities that adequate safety precautions are in place.

Certification needs to be reviewed every 12 months, and after any renovation work has been carried out, to ensure the property continues to meet the latest requirements.

NEW LIGHTING CATEGORIES

The updated standard includes requirements for a much broader array of emergency lighting categories than before.

In addition to escape lighting – to illuminate evacuation routes in the event of a fire – BS 5266 now stipulates the inclusion of emergency safety lighting that allows occupants to see their surroundings in the event of a mains supply failure and the loss of normal lighting. It is strongly recommended that this equipment has automatic testing.

Any stand-by lighting – to provide full www.theilp.org.uk

ing and offering the correct lux level.

Under the new guidelines, testing should be carried out at a period of low risk, or while the building is empty, to minimise risk to occupants. Alternate luminaires should be tested in any 24-hour period to ensure the building always has a charged, fully operational evacuation system available. Systems should also be tested for their full rated duration, so as to make sure they meet specified performance requirements.

The simplest way to achieve these requirements is incorporating a certified EN 62034 automatic testing system.

visibility in the event of a supply failure – needs to be upgraded to meet the standard’s usual escape lighting system requirements. This entails carrying out a risk assessment to identify areas that may require back-up lighting in the event of a power outage. Rooms smaller than 60m2, for example, might not need escape luminaires but would require stand-by lamps in the case of mains lighting failure.

The standard recommends procedures are put in place to determine whether premises need to be evacuated straightaway in the event of a safety incident and, if a ‘defended place’ or ‘stay-put’ solution is agreed on, to direct occupants to safe refuges. Again, an emphasis has now been placed on automatic testing in such situations.

HIGH RISK AREAS

LIGHTING REQUIREMENTS

TESTING AND MAINTENANCE

Lux level guidance for escape lighting remains the same as in previous editions of the BS 5266 standard. However, there are additional requirements for ‘open areas’ inside large buildings to ensure that ‘inner rooms’ are adequately lit during an alert.

The standard now includes a host of design conditions for lux calculations to ensure lighting remains at the minimum required level for the duration of a potential incident. The effects of a reduction in voltage, ageing batteries and lamps, as well as the accumulation of dirt, should be taken into account. Light reflectance should also be removed from measurements.

In addition, non-illuminated Perspex, photo-luminescent or self-adhesive exit signs should be illuminated to 100 lux under normal circumstances – when mains lighting is operating normally – and to 5 lux in the event of a supply failure. www.theilp.org.uk

The updated BS 5266 also brings new requirements relating to emergency lighting for ‘high risk’ areas, or spaces where potentially dangerous processes are carried out.

In such areas, it is now advised to implement procedures to automatically shut down any hazardous operations. Lux values of 10% of the mains light level or 15 lux (whichever is greater) should always be adhered to. However, a risk assessment could indeed reveal a requirement for higher levels, depending on the risk.

Of equal importance is the time for the emergency lighting, whatever the category, to switch on. In high risk areas, this should never be more than 0.5 seconds to minimise the risk of harm to occupants.

All emergency lighting systems, whatever their category, should be tested at least once a month, to ensure they continue to provide optimum performance. A competent engineer should be appointed to perform monthly testing, and to provide routine maintenance to ensure optimum performance across the whole emergency lighting system.

These monthly tests should include checking the power supply of each luminaire, if the indicator is not lit, and cleaning each lamp to maintain recommended lux levels. For existing fluorescent installations, individual luminaires should be replaced once their black ending has reached a point where it will reduce lamp output below those stipulated by the standard.

In addition to the monthly tests, each luminaire must be visually inspected no less than once a year, to ensure it is work-

In the event of identifying a failure in any part of the emergency lighting system, BS 5266 requires that a qualified engineer carry out corrective action. It also recommends that alternative safety procedures be put in place until the repair is complete and the system has been retested satisfactorily.

The updated standard also stipulates the duty holder for the building should decide on the appropriate action to be taken for their premises to ensure occupants’ safety while the fault is fixed. Possible measures include warning building users to be vigilant for the duration of the repairs, initiating extra safety patrols, issuing torches in the affected areas or, in rooms identified as high risk, limiting access altogether.

NEW DOCUMENTATION

In addition to the new guidelines regarding lighting categories, lux levels and maintenance, the standard has updated documentation requirements.

There are now some 13 annexes, containing guidance on a wide range of issues, from a summary of the standards relating to emergency lighting, to advice on emergency lighting categories and their recommended applications, to information on calculating lux levels. Information on filling out logbooks and carrying out inspections is also included.

Finally, of course, the standards relating to fire detection and emergency lighting are updated all the time, reflecting the evolving safety requirements of the built environment. It is crucial that all professionals do all they can to keep up with these changes in order to ensure their premises remain legally compliant.

The 2017 LewesLight Festival

SUSSEX STORIES Next month’s LewesLight festival in Lewes in East Sussex is unusual in being about more than just attractive installations and artworks. It is about showing local communities the role and power of public realm lighting, raising awareness of environmental and dark skies issues, and inspiring future generations

he LewesLight Festival, in my home town of Lewes in East Sussex, is entering its third year and going from strength to strength. This year the festival will run from 13-15 October (from 7am to 11pm each day), and we have invited more designers and artists to the fold, as well as introduced sound, music and poetry to the mix.

For those unfamiliar with the event, LewesLight is a lighting festival but, unlike many other festivals, it is design-led, with all of our installations context-based and site-specific. This means they feed into a wider range of integrated threads, incorporating narrative and storytelling, as an exploration of the town its people and history.

Whilst the festival aims to draw visitors to the town, so raising its profile as a tourist destination and benefiting the night-time economy, it is also very much a community event, engaging with local people and business and working extensively with local colleges and both Sussex and Brighton universities.

For example, we partner with the town council and are supported by Lewes District Council. We collaborate with the South Downs National Park Au-

thority to raise awareness of dark skies and environmental issues and best practice in lighting within the South Downs Dark Skies Reserve.

COMMUNITY FOCUS

So, how are we different? Many festivals are art commission-based and, whilst some installations may be site-specific, many are not; they may work in context of the place in which they are located, but they don’t necessarily resonate with their surroundings on more than a superficial level, or at such a high level that, intellectually, the concepts behind the work make them less accessible to a wider audience.

That is not to say this type of installation cannot be truly beautiful, dramatic or carry significant intellectual meaning – I don’t wish to diminish such work in any way. But, as a designer, I like to see something that works differently.

At LewesLight, therefore, we aim to deliver, and celebrate, a narrative about Lewes, its history and its people. We provide attractive and interesting installations but also deliver much more, by way of storytelling. We bring an exploration of history, in particular, to younger people in a stimulating and exciting way.

This year we have an even greater number of designers and artists taking part. Lighting designers and artists include Ellie Coombs and a team from Nulty+, Claire Hamill, Karen Van Creveld, Chris Beasley, and Susan Lake.

There is a team from Studio Fractal, plus Jack Wates, and James Duffin. Also throwing themselves in will Margareth Sunjoto from Studio 29, Pedro Pinto, Guyan Porter, Maggie Lambert, Mick Hawksworth, Art Lewry and Jack Beccegato, Leora Honeyman and Neil Marsh.

We are this year working with the poet and writer John Agard and composer Ruth Kerr. Again, we are supported by a team of local historians, who are advising us and who will help to develop our guided walks.

SHOWCASE FOR LIGHTING DESIGN

You may ask how we are able to put together such a large and diverse team who are all prepared to contribute their time and effort pro bono?

First, there is the attraction of having the freedom to work on a creative project with minimal client intervention. Our brief is wide and, whilst the event is curated, it is our ethos that designers and artists

should (as much as possible) have a free reign to deliver what they feel is right within the theme and context of the festival.

Second, there is the issue of professional profile.

LewesLight is a showcase for designers to demonstrate how lighting can affect public space and contribute to a narrative, as well as a promotional tool to market the town, tourism and local business.

Finally, we are very clear in wanting to demonstrate best practice and raising awareness of the environmental issues of lighting, especially in the context of the dark skies reserve. For all of us, as a community-based event (and as many of our team have a local connection), it is about putting something back, giving something back.

This also means education has played an important role in the ethos of LewesLight from day one.

We are partnered with the local further education college, Sussex Downs. In fact, the festival is embedded into both its Production Arts and Digital Arts courses, with students’ work on the festival contributing to their final grades. Providing this age group, 16-19, with access to work with professionals, to be exposed to the design/creative process as well as valuable STEM-related skills, is a fantastic opportunity.

‘TRADE, INDUSTRY, AND COMMERCE’

The over-arching theme for LewesLight this year is ‘Trade, Industry and Commerce’, with stories and ideas explored touching upon topics as diverse as alchemy, the stars, scientific genius (or fraud/‘fake’ news!), harpsichords, religion, social and economic change and literature. As well as the main festival, there will be a short se-

www.theilp.org.uk

ries of talks discussing some of the ideas explored and the wider impact of light and lighting.

We are all very excited about this year’s festival; as it grows we can apply lessons learned over the first two years. I feel confident that, with the skill and enthusiasm of our team, it can only get better.

We are still operating with minimal funding and on a shoestring budget, and therefore I need to draw particular attention to our industry sponsors who provide equipment free of charge and in some cases also financial contributions.

At the time of writing, these were: ACDC Lighting, Architainment, Commercial Lighting Systems, Encapsulite, iGuzzini, Kingfisher Lighting/Arcluce, LED Linear, Light Graphix, Light Projects, Meyer, Rosco and SORAA. Finally, of course, I very much hope you – and as many ILP members as possible – will come along to LewesLight this year and support the work we’re doing to promote the role of lighting, and lighting design, within the community and public realm, and within the hearts and minds of students and young people. I look forward to seeing you there!

Flicker

WAVEFORM AND FUNCTION One of less welcome side-effects of the transition from fluorescent lighting to LED has been the return of flicker as an issue, as many LED drivers operate at lower frequencies or contain lower frequency components. Yet there is, as yet, no worldwide recognised standard with appropriate methods to test for flicker

uch has been written and said about Temporal Light Artifacts (TLAs) or flicker and stroboscopic effects. What is essential to understand about TLAs is they are normally induced by a light stimulus whose luminance or spectral distribution fluctuates with time and causes undesired changes in visual perception for an observer in a certain environment. This short paper is designed to give an overview of where low flicker is critical, and where it isn’t, discuss issues such as Flicker Percent and Index, and outline some of the testing procedures that we at UL recommend needs to be put in place.

WHERE IS LOW FLICKER CRITICAL, AND WHERE ISN’T IT?

Flicker can cause a range of health effects, both serious and less serious. These can include headaches and eyestrain and, at the more serious end of the spectrum, can trigger photosensitive epilepsy.

As well as these health factors, the stroboscopic effect of non-visible flicker of >70 Hz – or where the flicker causes running or moving equipment to appear stationary or to be operated slower than it actually is – can cause a host of problems in an otherwww.theilp.org.uk

wise well-designed luminaire or space.

For example, it is not a good idea to have a stroboscopic effect in an installation open to the public where a high quality of light is required or where video recording may be necessary. A stroboscopic effect in a sports environment can lead to motion being wrongly perceived.

Different situations require a different focus on flicker, largely based on factors such as location, historical experience, likely exposure time and the sorts of activities taking place. The difficulty for lighting professionals is that, although some documents providing measurements’ metrics have been published on this topic, there are contradictions among them. A further complication is the fact that dimmable products are not yet addressed by the available documents.

So, what’s the answer? A worldwide recognised standard with appropriate test methods would be the best solution for the lighting industry. But, in lieu of that (and after taking all the published literature into consideration), simply understanding considerations such as Flicker Percent and Flicker Index, and understanding some of the testing requirements, can be helpful.

We shall now look at both these areas.

FLICKER PERCENT AND INDEX

Flicker can be more or less apparent depending on several factors, primarily the relevant amount of variation in the light per cycle, the proportions of the lighting waveform, and the frequency (or frequencies) at which the light variation occurs.

To describe this variation within a cycle, there are two primary measures: Flicker Percent (FP) and Flicker Index (FI).

FP is the measure of the maximum light versus the minimum light in a cycle. This only accounts for the minimum and maximum light outputs, and does not differentiate between waveforms.

FI, by comparison, describes the behaviour in terms of the amount of light that a product produces over a given cycle.

Flicker Index requires more calculations than Flicker Percent, as it considers the area of the waveform above and below the average light output.

The difference in perceptibility in these two metrics is one that is still open to debate. However, it is generally acknowledged that the perceptibility of both is dependent on the frequency at which a product operates.

With the shift to electronic ballasts operating at 40 kHz or more for greater effi-

September 2017 Lighting Journal

ciency, flicker issues were largely eliminated from fluorescent lighting. However, flicker has reappeared with LEDs. There is a balance between size, cost and lifetime when designing drivers, and many LED drivers operate at lower frequencies or contain lower frequency components that can cause perceptible flicker.

These metrics do not quantify TLA effects correctly and objectively. Flicker Percent and Index do not distinguish between ‘flicker’ and ‘stroboscopic effect’, nor do they account for the effect of frequency-dependent sensitivity or the wave shape of the light output.

Several studies have demonstrated that, even if a population has different threshold sensitivities, flicker is visible up to 7080 Hz. ASSIST metric, developed by the Lighting Research Center in New York State, complements the other two by providing a numeric value that can be used to predict flicker perception.

to two seconds. Dimple products have additional requirements.

Signals acquired To determine flicker, data must be processed using the ASSIST metric. It also important to recognise that lighting system design and dimming can influence perceived flicker.

The above flow-chart (Figure 2) illustrates the necessary steps that a good metric must include to obtain reliable data.

The ASSIST metric takes into account the wave shape of the light waveform. But do bear in mind that the possible limits of this metric may be: • Short duration of the waveform is not sufficient for detecting low-frequency flicke • Flicker because of single-event modulations is not detected.

CONCLUSION

Though many grey areas still exist regarding TLAs, market understanding continues to grow and evolve.

A worldwide metric with standardised test methods would allow the global lighting market to better rate and understand product differences, but more work is needed before a metric can be implemented.

In the meantime, we – as others are within the industry – will continue to work with the global lighting community in an effort to increase understanding, improve testing, and help to ensure the safety of those using artificial light. ¢

‘I’D LIKE THE ILP TO BECOME THE NATURAL HOME FOR NEW YOUNG LIGHTING DESIGNERS’ The ILP is a broad church that encompasses engineering and non-engineering lighting professionals. But that also means the ILP has a unique responsibility to share cross-disciplinary skills, knowledge and expertise

his summer is the first anniversary of my taking on the role of VP Architectural for the ILP and, after a year of finding my feet, I can now report on progress, and how the ILP is developing its remit to encompass lighting designers working in architecture, landscape and public realm further into the institution.

After a number of years creating and developing the role of VP Architectural, Mark Ridler has left me with a firm base to build upon and, whilst he has stood down as VP, he has continued to work on a project to broaden the ILP’s involvement with lighting research. This will be reaching fruition soon and we look forward to hearing about it in the near future.

Now I have had the opportunity to examine my role, to discuss opportunities with the ILP team and fellow VPs, and to speak with members and potential memwww.theilp.org.uk

bers, I am able to formulate an approach which I can share with you here.

The ILP’s strengths relate primarily to exterior and public realm lighting and, whilst most architectural designers will be involved in projects with a much wider scope, in the short term I wish to focus on this, building to encompass other areas of lighting over time.

One of the ILP’s strengths is that it is a forum where non-engineering-based designers and engineers can engage in constructive dialogue and collectively develop skills and knowledge. This is an area I see can be expanded.

Another important part of the ILP community is manufacturers, contractors and suppliers; historically street lighting companies have played a significant role in the Institution and, as we provide a forum that is not exclusive to designers, we hope to encourage wider engagement with this sector of the lighting community in the architectural world as well.

The architectural lighting profession has grown dramatically over the last 20 years and, consequently, there are many more young people entering the profession than ever before. I would like to see the ILP becoming the natural home for many of these new designers in the UK, providing opportunities in education, professional development and networking, both formal and social. As such, I see closer collaboration with YLP as key to the future of the Institution.

So how are we going to deliver this?

September 2017 Lighting Journal

EXCELLENT SPEAKERS

Firstly, I wish to continue and expand on what we do well, in particular the 'How to be Brilliant' series of talks which has attracted many excellent speakers in an informal and welcoming atmosphere. Watch out for a review of July’s talk by Colin Ball in next month’s edition of Lighting Journal!

We hope to continue these but also to expand the series to hear from some younger designers speaking about their inspirations and influences and to provide a forum for them to gain experience of speaking in a friendly environment.

I would also like to expand our one-off events, such as the recent and very successful Lighting for Good event where a range of topics were discussed about how lighting affects people.

Training is an important part of the ILP’s activities, and the recent introduction of a one-day electrical course for non-engineers proved highly popular. The Exterior Lighting Diploma will also be having a makeover in the coming months, and some aspects of the course will become more relevant to the wider lighting community. We also hope to introduce training on CDM in the not too distant future.

TECHNICAL GUIDANCE

One of the ILP’s core activities has been its involvement in setting standards and the preparation of technical guidance.

We hope shortly to be involving architectural members in this process by feeding our views and comments into the review of BS 5489, and also the writing of new technical guidance notes relating to exterior lighting, application of standards and the preparation of production information.

The ILP is currently reviewing the definition of competence and we will be engaging with architectural members in this process.

As an engineering institution, we wish to encourage members to register with the Engineering Council, and will continue to offer support for those that wish to do so, in particular those (like myself ) who qualify through experience gained in architectural lighting design rather than through a formal engineering education.

This is an exciting time for the ILP and the lighting profession in general. I look forward to working with the ILP and you, our members, to deliver on these aims and objectives. ¢

The ILP’s Lightscene

BLUE-SKIES THINKING Blue light and colour temperature will be the focus of next month’s ILP Lightscene CPD event, and interest is already building

By Nic Paton

L

ast year it was ‘Smart Cities and IoT’, this year it is set to be equally fascinating, with a day of discussion and presentation around the topic of ‘Blue light and colour temperature within LED’.

What is ‘it’ that we’re talking about? The ILP’s regular Lightscene CPD event, of course, this year hosted by the ILP Midland and London & South Eastern regions, along with the YLP. This year Lightscene has moved from the spring to the autumn, largely as a response to the Professional Lighting Summit having now moved in the other direction.

This means members get to benefit from a regular stream of CPD activity throughout the year, running from the Professional Lighting Summit, through Lightscene, LuxLive and Light School, as well as local, regional and other events.

Lightscene itself is an opportunity for members to spend a day listening to a range of informative and thought-provoking CPD presentations, network with colleagues and peers and engage with industry providers and suppliers.

Last year’s event in Sunderland attracted more than 100 ILP members and the www.theilp.org.uk

hope is this year’s Lightscene, which is being held at the Northampton Saints Rugby Ground, will prove equally popular.

At the time of writing (in August), more than 16 exhibitors had already signed up for the event, nine of them ILP Premier corporate members, and more are expected to come aboard during September.

One Premier member who will be at this year’s Lightscene is Charles Endirect, and sales and marketing director Andrew Jackson said: ‘Charles Endirect is looking forward to meeting and networking with existing and new friends and customers at Lightscene 2017.’

INCREASING IMPORTANCE OF CPD

Richard Frost, ILP chief executive added: ‘As members will now undoubtedly be aware, the Engineering Council is making CPD mandatory from 2019.

‘The ILP’s CPD calendar, comprising the Professional Lighting Summit, Lightscene and an array of other regional events, is therefore only going to become more important. Events like Lightscene are also simply a great way for members and lighting professionals generally to meet and get together.’

Although the exact shape and format of the event has yet to confirmed, the likelihood is it will follow the model of last year’s Lightscene and offer a number of free CPD sessions during the day, followed by a fourth session later in the afternoon specifically for Premier corporate members.

Lighting Journal will also be there, and will bring members a write-up of the day after the event.

Anyone interested in exhibiting should contact go online to www.theilp.org.uk/ events/lightscene/ or contact jo@theilp. org.uk or call 01788 576492.

Visitor places will be free and will be able to be booked in advance when booking opens during September. Advanced bookings will also entitle you to free refreshments and lunch.

Full details on the speakers and presentations will also be revealed during September, and members are advised to keep an eye out for the online newsletter, or go online, at www.theilp.org.uk, for regular updates. ¢

‘THE FACT NO FEWER THAN THREE CURRENT VPS ARE EX-YLP MEMBERS SHOWS JUST HOW IMPORTANT YLP IS TO THE ILP’ As YLP chair Chris Rayner prepares to hand over the Young Lighting Professionals baton to Sofia Tolia, he reflects on the highs of his year in office. Opposite, Sofia outlines her hopes and ambitions for the YLP this year

A

s a long-standing YLP member I have had the pleasure of working with many YLP chairpeople, and the one comment I’ve heard many times is, ‘it comes and goes so fast’.

Now I’ve done my own chairmanship I realise just how true this is. As I write this (in August), my penultimate event as chair is fast approaching – our YLP technical session at NAL in Worcester in September – before I hand over at the AGM in London in November to Sofia Tolia.

My year has been a really good experience, but it is bitter-sweet that it comes to an end at the AGM. Not only will it be my last event as chairperson, but it will officially be my last ever YLP event – as I crossed the age threshold earlier this year.

My year started off with a great event up in the north east of England, where we were able to do a double-header of meetings. We first attended Valmont Stainton for some technical papers on column specification and column design as well as a guided tour around the facility.

This was followed up later in the day with a mini paper competition, which was four members of the YLP giving individual presentations to the North East region.

This was a great event. It was well attended by the region and the YLP, and it was very www.theilp.org.uk

encouraging to see what kind of support the YLP has in the region.

Our second event was held at ASD Lighting in Rotherham, and again was a great mix of technical papers followed with a factory tour of the facility. Trying to get a mix of papers and tours, I felt, was key to a good technical day’s content. It gave the members a lot more freedom to interact and get the full benefit from the day.

Our third session was a technical paper day, which consisted of four papers held over the course of late morning and early afternoon at CloudFM.

Speakers from INDO Lighting, Salix Funding, Stainton Lighting Design Services and Cloud FM themselves made for interesting topics of conversation and covered a wide range of current topics within our industry.

In conjunction with these speakers, we were also able to have four VPs at this event, all giving up their valuable time to come and address the members who attended and inform us of what they are looking to achieve in their roles.

It is always nice to hear that a fundamental part of the future plan involves as much input from the YLP members as they can all get. The main aim is for the YLP to bridge the gap between old and new in the industry, and hearing VPs speak so highly of the importance of this – and the fact is that no fewer than three of the current VPs are ex-YLP members – shows just how important we are to the Institution, but also the benefit of YLP to members.

Finally, I would like to take this opportunity just to say a big ‘thank you’ to all the companies and staff members that have allowed us to hold meetings at their premises; to all the dedicated members of the YLP who have attended the meetings in support of the events and building their CPD; and to my committee for helping the

ore than three years have passed since I joined the YLP committee as a Highways and Infrastructure representative, and it is a great honour for me that, from November, I will be the chair of YLP. I have had the pleasure and privilege to co-operate with remarkable past chairs and committee members, although that only adds an extra level of responsibility as I know what a high level of competency I will need to sustain!

At the same time, it is a great honour to be chairing such an exemplar committee, with such supportive members. I would

like to take this opportunity and express my sincere gratitude to my fellow committee members and past chairs for trusting me with this title.

My main goals as YLP chair will be: to keep encouraging more young lighting engineers to be involved with the lighting industry; to maintain the network; to ensure knowledge and experience is being shared.

Continued professional development is, of course, key for everyone’s career. Therefore, my plan is to organise technical seminars covering a wide range of topics, varying from factory visits to detailed information on membership upgrades and updates on new technologies and design methods (please contact me through the YLP if you wish to present a technical paper).

A possible social event will be held, and more details will be circulated in the near future.

Last but not least, a big ‘thank you’ to our members and the companies and employers from the lighting industry. Without their continued support, this committee’s vision would not be able to come to fruition.

I am looking forward to an amazing year with the YLP.

The ILP 2017 Professional Lighting Summit

‘THE LEVEL OF ACCEPTANCE I FOUND WAS HUMBLING’ 46

The ILP always encourages students to attend its CPD events, and this year’s Professional Lighting Summit was no exception. Graduate engineer Rojy Mathew reflects on his experience in Glasgow

By Rojy Mathew

I

gingerly eased myself into the ILP presentation room of the Crowne Plaza hotel in Glasgow. I felt like a student arriving late to a lecture, trying to ignore the lecturer and find my seat.

A lone, strong voice was speaking into an attentive silence. Alan Jaques, new President of the Institution of Lighting Professionals, was making his opening address to the Summit.

I felt intensely fortunate to get an opportunity to attend this Summit; to gain an understanding of an industry I would not normally have experienced. Unfortunately, I had no idea what a ‘Professional Lighting Summit’ exactly entailed, and now here I was, feeling somewhat like a gazelle amidst lions – and with a big lanyard around my neck with the word ‘student’ on it – trying to slip in discreetly!

I needn’t have been worried. Between a combination of fascinating presentations and a friendly welcome everywhere I turned, a ‘Professional Lighting Summit’ I quickly discovered was something to be embraced rather than to be afraid of.

The first presentation I heard – by Mark Sutton Vane (pictured giving his talk, right) – examined the relationship between light and people. Being animals with www.theilp.org.uk

developed eyesight, we humans have a strong dependency on visible light, being as it is the primary medium through which we perceive the world. However, the focus was using this knowledge as a means of control, controlling our perception and understanding of the environment around us.

Displays, buildings and streets can use the presence and absence of light to direct attention and flow of people. Architecture and design, it was clear, is not just the business of concrete and metal, but visibility, through light and darkness, as well. This was a novel thought to me at the time.

EFFECTS OF LIGHT POLLUTION

The second presentation was a personal and wide-ranging discussion by Steve Anderson very much focused on the positive and negative effects of LED within the environment.

Of course, I know the theory of light pollution, but it was different when hearing about it from a veteran engineer, especially the personal-scale examples, unfolding problems and his suggestions for hardwon solutions from the field.

I then decided to check out the exhibition hall. This was much smaller than the presentation room and, by the time I arrived, a sizeable crowd was making its way about the exhibitions.

Perhaps 20 such exhibitions tables were present, each helmed by company employees. Taking a deep breath, I quickly jumped in although, not having a clear plan, I elected to approach every table with zero subtlety!

I spoke to fresh graduates as well as experienced veterans. I learned about general outlines of street luminaires, street sign conspicuity, heat management, VR and smart cities, among many other topics.

I was learning about subjects that I would never have thought about. I was getting a multi-flavoured slice of information that contained many different aspects about this industry. I only wish that I had more time and looked less like a rookie, but that did not seem to matter.

I felt conscious about my ‘graduate’ status, but all anyone else saw was a fellow engineer. The level of acceptance I found at each table was humbling. To be allowed into this environment, one filled with new ideas and innovative engineers, was an honour.

The Summit lasted for two days. I was an outsider and a student for half a day. I was an engineer for the remainder. For this I would like to thank the presenters and exhibitors and, of course, the ILP (through Jess Gallacher) for the opportunity to attend.

I met like-minded people who I would be honoured to call peers; I experienced an environment focused on encouraging my talents. And, if nothing else, I learned a new word: conspicuity!

UNIVERSAL SYSTEM READY SOCKETS FOR LED LIGHTING A new universal ‘system ready’ (SR) socket for LED street lighting installations addresses the constraints of 7-pin Nema sockets whilst delivering enhanced functionality. *Steve Austin and **John Fox explain how contractors and local authorities can benefit

Why is there a need for a new Can you tell us what new Q:already System Ready socket when we Q: possibilities the SR Socket can have a 7- Pin Nema bring to the lighting industry? socket?

SA: “As compared to the 7-Pin Nema socket, the System Ready (SR) socket can be more easily incorporated across a wider range of luminaires. It has superior fixation and higher IP rating (IP65). Its ultra-sleek design makes it more aesthetically appealing, especially in combination with the new breed of LED luminaires, including architectural designs.”

Q:

How does the new SR Socket help in better photocell integration?

JF: “The SR socket is an open connectivity interface that has been developed by TE Connectivity Corporation and is now available to the lighting industry. This innovative technology has allowed Lucy Zodion to reduce the size and profile of the photocell significantly, allowing us to develop the first low voltage configurable light sensing device (Precizion HALO) for LED street lighting.”

JF: “It is a great solution for integration of smart city devices. It is designed to provide considerable flexibility to customers in terms of connectivity and allowing them to attach a range of upward and/or downward facing sensors to LED System Ready (SR) street lights.

This means that local authorities can use their street lighting infrastructure for much more than just lighting, by connecting light sensors, presence detectors, noise and air quality sensors, cameras etc. now or in the future.”

Q:

How would you sum up the main benefits of the SR socket for installers and end clients?

SA: “The SR socket is DALI 2 compliant and allows the SR driver to provide a low voltage (24V) supply to various CMS (Central Management System) OLC/node and/or sensors on the luminaire. This offers customers the first ever solution that does not bring 240V AC to the exterior of the luminaire. This

in turn negates the risk of fatal electric shock when compared to a 7-Pin Nema solution. It is also significantly smaller, whilst still enabling tool-less mechanical attachment and replacement of outdoor lighting controllers (OLCs), photocells and sensors. The revolutionary SR socket, gives the lighting industry the opportunity to make the leap to a safer, smaller and smarter interface that makes our street lights ready for the future upgrades.” will certainly be very Q:HowReaders interested in this innovation. can they find out more?

SA: They can contact either Philips Lighting or Lucy Zodion and we will be very happy to discuss the SR socket in more detail, or send additional information. You can visit www.philips.co.uk/smartcities OR www.lucyzodion.com for more information
