Energy efficient lighting
NEWS Time, times nine
Sharing in Austria The LED technology sector has been driven by numerous innovations during the past year. GaN-on-Silicon technology, nano-technologies and production methodologies are now ready to enter the market. However, Siegfried Luger, event director of the LpS, warns the lighting industry needs regulations and standards. He suggests that t is necessary to have a mutual exchange of scientific knowledge, discussions about promising solutions and a network that brings key players from the areas of science and industry together. This is the central idea behind the annual LED professional Symposium +Expo (LpS), which takes place in Bregenz, Austria from 24-26 September, which has established itself as the leading LED lighting technology event in Europe. Apart from the numerous presentations in the fields of component, measuring and production technologies, the important topic of decreasing research & development costs will be discussed by Menno Treffers, Secretary-General of Zhaga.
Londis cuts costs MHA Lighting has helped Londis slash its energy bills. The project, at Hillnews in Darlington will cut lighting energy bills by 63 per cent. Traditional fluorescents were replaced with TiLite fittings. Owner, Andy Hill said: ‘We sought a new solution after the costs associated with replacing our existing fluorescents with like-forlike became too much. We conducted an extensive procurement process and selected MHA Lighting because of its reputation and proven ability to design and install bespoke projects at other convenience stores.’ With the store’s 15hour working day, the lighting is able to provide an ROI of 439 per cent, by significantly reducing annual energy consumption from 16,767Kw/h to just 6,140Kw/h. Hill continued: ‘The new LED lighting has considerably improved lighting levels and is significantly reducing our on-going energy costs, which for me is essential.I was particularly impressed with how vibrant the produce looks and the reduced flicker on CCTV monitors, which has dramatically enhanced clarity of the CCTV footage.’
Andover-based LED Synergy has completed an unusual project for the Sheikh Zayed Grand Mosque in Abu Dhabi, one of the largest, most elaborately decorated in existence. The brief called for nine LED-based prayer clocks, with a micro-controller system which had to be programmed to show complicated, year-long Salaat time based content, including information that would be displayed across the entire religious year on a rolling cycle. ‘Programming of the control system was far more critical than the displays, and was where our expertise and previous experience came to the fore,’ explained Jeremy Harwood of LED Synergy. ‘The Mullahs responsible for this mosque, could have gone to any LED solution supplier around the world, but chose to come to us because of our reputation, and the fact that we clearly understood the complexities of what they wanted. ‘More importantly we could deliver and guarantee a robust solution that met their needs. While price was still important they had to be 110 per cent sure that our solution would consistently perform and without any glitches.’ The gold-inlaid marble clocks feature eight high-definition, single-colour LED panels and a central analogue clock, to provide the exact details of each of the six prayer times each day in both Arabic and English text. The prayer board micro-controller, which stores in excess of a year›s Salaat times, automatically updates using an internal timer, but it can be over-ridden using an Excel spreadsheet or an infrared keyboard. The Muslim annual calendar - and the constantly varying Salaat-based prayer times each day - were individually programmed in advance to allow the clocks to automatically display the exact information for each day.
First foray Verbatim is to start selling lighting fixtures designed to complement its LED lamps. The fixtures are designed to fit Verbatim’s PAR16 GU10 lamps, making l lighting upgrades for both domestic and commercial applications simple and economical. Sold through B2B and trade channels, packs comprise a fixed ring plus a holding pin, a GU10 socket and electrical connection box. The fixtures are available in two different IP protection ratings. While the IP23 rated version is suitable for general-purpose lighting including kitchens, living rooms and bedrooms, the IP44 version offers defense against intrusion from splashes, making it ideal for lighting in bathrooms.
GAME, SET & MATCH The owner of Woodlands tennis club in Bristol has implemented a series of energy saving projects, which have resulted in a reduction of its annual electricity and carbon consumption by 82 per cent. Each year, the savings translate to £721 in electricity, 4,100kg of CO2 and 7,589 kWh of energy. Surprisingly, these savings were simply as a result of
updating the lighting. These figures should be encouraging to other sports clubs, looking to lower energy bills, but may be unsure where to start. Understanding where energy is lost is an important precursor to reducing their carbon and electricity consumption. In the short winter days, outdoor sports clubs become increasingly dependent on
floodlights. As a consequence, energy consumption is at its highest during this period. Mindful of this issue, Woodlands sought a cost effective alternative to the existing 20-year old fittings. The club engaged Premium Lighting Solutions and Lockwell Electrical Distributors to assess the situation. After reducing the number
of lights from 16 to 14 and replacing them with PLS floodlights, the results were immediate. As well as energy savings, club members noticed that the new lighting eliminates the strobe effect inherent to many traditional low energy lighting systems; this means better visibility of fast moving tennis balls. Keith Wyatt,
commercial director at Premium Lighting Solutions suggested: ‘If you are considering investing your money in energy-saving projects, a comprehensive energy audit is essential. This will enable you to assess your individual requirements and match those with the ideal lighting model.’
