Nafir – Pure imagination Design Karim Rashid

“I wanted to create a functional product that was part sculpture, that was truly beautiful even with the lights off, that would allow beguiling combinations capable of creating a fantastic panorama of lights and shapes”. Karim Rashid Fluid, liquid, emphatic, glamorous. This collection that recalls a row of trumpets lined like bunting stems from Karim Rashid's brilliant imagination. Organic shapes that create a fantastic panorama of lights and shapes. Nafir touches upon the sculptural theme: available stand-alone or in groups of threes (a textured and flowing osmosis of 3 lampshades) and illuminated by LED technology, it is just as enchanting with the lights off. The designer sketched them while thinking of light as a complement to music, imagining a fluid surface pulled upwards in several places: the threedimensional handling of the surface, little by little, took shape and began its transformation into an object that resembles a trumpet. Nafir's fluid and dynamic shape is intended to be the expression of light itself, as if the casing wanted to become/appear an integral part of what it contains, while also expressing the idea that light, like music, is pure emotion. Its name is also a tribute to music: Indeed, the term Nafir is used to indicate a small North African trumpet, without pistons, used to obtain especially acute sounds. Nafir is designed to allow the creation and customisation of an endless number of compositions suitable both for residential and contract use. A triumph of vitality and an unmistakable sign for a fabulous collection of lamps that remains the crux of the purest refinement. Nafir is made of white injection moulded plastic and is available in three different colours: chrome exterior/white interior, white exterior/gold interior and white exterior/white interior. The canopies are made of the same material as the lamp and with the same colours and finishes. Dimensions: single version Ø20 cm x H. trumpet 30 cm / total suspension height 180 cm – triple version - overall dimension of approximately 50 cm in Ø x H. trumpets 30 cm / total suspension height 180 cm. From 2013 Nafir is available also in the ceiling (one or three lights) and in the recessed downlight (three lights) versions. The light source is GU10 LED which guarantees excellent performance levels in terms of energy savings and is readily available in shops. 8 | March-April 2015 | lightexpress

THE WORLD’S ENERGY EFFICIENCY MARKET IS AN “INVISIBLE POWERHOUSE” WORTH UP TO $360 BILLION Energy efficiency saved US$743 billion in 2011, with investments in the sector worth between US$310360 billion in 2012. These findings come from the just released Energy Efficiency Market Report 2014, by the International Energy Agency (IEA). From energy-saving LED lights to smarter homes, appliances and cars, energy efficiency is a booming market. The IEA calculates that in 2012, investments in this sector were worth at least US$310 billion, up from the US$300 billion estimated for the previous year. In the 11 countries scrutinized in IEA’s second annual report on the subject, energy efficiency spending totaled more than US$38 billion in 2012. LED lights in particular are one of the most promising markets that make up the emerging sector. In Japan, LED sales reached US$5.2 billion last year, representing almost one third of all bulbs sold in the country, while India is forecast to have a cumulative total of almost 34 million LED bulbs by the end of this year. IEA states the growth in the energy efficiency market is partly due to investments through public finance, especially in Germany, as well as development aid programs. The segment is also benefiting from specific instruments such as climate bonds and energy service companies, the latter of which totaled US$12 billion in China last year. ENERGY SAVINGS The report also calculates that the

energy savings of the 11 countries from the 1970s to 2011 was 1,337 million tons of oil-equivalent (Mtoe). This figure is more than half (59%) of the total final consumption (TFC) of all fuel sources in all 11 countries. In fact, the total avoided energy use is higher than the TFC of any single fuel source. In the same time span, these countries consumed 1,202 Mtoe of oil, 552 Mtoe of electricity and 509 Mtoe of natural gas.

despite a fast-growing global population, efficiency helped cut energy demand 5% over 10 years through measures like improving space heating and better lighting. On top of curbing problems relating to surging energy demand, the energy saving potential of efficiency is also crucial at a time when fuel prices are rising around the world, with costs jumping as high as 52% from 2001-2011 in the US. However, expanding the research

ing to the study, the rules will save between 3.9 liters to 6.7 liters of gasoline equivalent per 100 kilometers, and save between US$40 billion and US$189 billion annually by 2020. The large gap between minimum and maximum projected figures is due to uncertainty about future policies, which underlines again the importance of governments in designing the future framework of a

From a regional point of view, the energy efficiency savings were larger than the TFC of the European Union or Asia, excluding China. Energy efficiency was 80% of TFC in China, and 87% in the US. Maria van der Hoeven, Executive Director, IEA, explained energy efficiency is now becoming an established market, at the launch of the report in Italy this week: “Energy efficiency is the invisible powerhouse in IEA countries and beyond, working behind the scenes to improve our energy security, lower our energy bills and move us closer to reaching our climate goals,” FUEL PRICE RISES The report also analyzes energy demand in 18 IEA countries, which together make up one third of global TFC. From 2001 to 2011, the TFC of these 18 countries was reduced by 5% largely due to energy efficiency, saving 1,731 Mtoe in just 10 years. On the contrary, without energy efficiency the TFC would have increased by more than 11%. In the residential sector in particular,

beyond the 18 countries evaluated can give a clearer identification of intervention areas - which can help governments to frame better policies and investors to unveil new markets. EFFICIENCY IN TRANSPORT The biggest and most promising market in the energy efficiency sector is small cars, known as ‘passenger light duty vehicles’. So far, it accounts for over 60% of all incremental investments, at US$80 billion per year. Within this segment, most investments are directed toward implementing new standards to reduce fuel consumption. Accord-

low carbon, energy efficient economy. FINANCING ENERGY EFFICIENCY Thankfully, several countries are backing the energy efficiency market, says IEA. In particular Italy has implemented a 55% tax reduction for energy savings investments - increased to 65% in some cases from next year leveraging more than US$29 billion investments between 2007 and 2013. In China, owing to the Five-Year Plan of 2006 to 2010, these investments exceeded US$100 billion and are forecast to grow US$200-270 billion between 2011 and 2015.

Chelsom create custom lighting scheme for the iconic Mondrian London original Sea Containers fittings were taken off site and refurbished by a team of restoration experts at Chelsom’s factory where they were cleaned, refinished and rewired to incorporate retrofit LED light sources making them compatible with the exacting energy requirements outlined in the brief.


orking in collaboration with Tom Dixon Design Research Studio, Chelsom created a dramatic custom lighting scheme for the guestrooms and lobby area of the first ever Mondrian branded boutique hotel outside the United States. Seductive and striking, Mondrian London at Sea Containers perfectly blends the style and sophistication of the famed boutique brand with Southbank’s eclectic vibe. Under the direction of renowned British designer Tom Dixon, DRS have succeeded in creating an interior scheme that captures the essence of the original building, exuding 1920s cruise ship glamour integrated with the contemporary twists and urbane design for which the Mondrian brand is known. This unique interior concept is echoed throughout the 335 guestrooms and suites. Chelsom were challenged with creating a distinctive custom-designed lighting scheme with post-modernism references, fusing cutting-edge design, functionality and energy efficiency. Matt black fittings with brass features accentuate the bold colour palette. Fixed to the

headboard, wall lights feature oversized brass rotary dimmer switches and multi-directional teardrop heads with retrofit LED light sources housed behind a frosted glass lens to offer both reading and mood lighting in a soft white ambient tone. The desk lamps feature an oversized tubular head and statement brass rotary dimmer switch while the conical spun metal shades of the floor lamps are finished in brass and lined in white to provide a bold contrast whilst optimising light reflection. To the specification of DRS, Chelsom created a trio of triple tiered pendants in matt black and copper for the entrance lobby. At 3.5m each in diameter, these circular fittings are suspended from the ceiling by metal support rods to create the illusion that the sculptural pieces are floating in mid-air. As part of a wider sound reducing concept for the lobby area, these fittings are clad in acoustic foam and incorporate state of the art LED downlighters and uplighters for optimum light output and efficiency. Chelsom also refurbished a series of more than 30 original Cliff Tribe wall lights dating back to the 1950s including double lights and triple pendants. The

Managing Director Robert Chelsom said, “To have been commissioned by Maison Objet’s Designer of the Year 2014, Tom Dixon, to be part of such a fantastic high profile project as the iconic Mondrian- possibly London’s ultimate destination hotel, is a real honour and testimony to Chelsom’s reputation within the industry. This was not just another order, it was a step into boutique design of the highest calibre and the

way forward for modern hotel lighting and for Chelsom. Obviously a project of this scale and stature was not without its challenges but the opportunity to work with such a fantastic team on one of the best lighting schemes we have ever produced meant this was a real labour of love from start to finish and one we are all very proud to be part of.” E T 01253 831406 W

he final list of speakers and topics has been selected from more than 260 submissions and the PLDC organisers are proud to present a high-class, futureoriented and innovative conference with speakers from 25 different countries! The conference programme for PLDC 2015 was released on 23. February, 2015 and is available at As in previous years, PLDC will be built around a four-track conference. Traditionally, the first three tracks will cover Lighting Application Case Studies, Lighting Application Research and Professional Practice Issues. The fourth track varies from convention to convention and is dedicated to a topic that is currently

key to lighting design developments worldwide. For PLDC 2015 in Rome, the Steering Committee has selected a topic in response to on-going market developments and studies: “Light and Culture”. The track will feature presentations on recently completed projects, indicate how lighting has changed in cultural spaces (museums, art galleries, cultural heritage sites, etc.), how different cultures perceive light and consequently how this influences lighting design. The impact of new technologies on the culture of light, and how their application is shaping design or lighting strategies, will also be addressed in this track. Austrian media-artist, director, choreographer and composer Klaus Obermaier has been announced as the first Keynote Speaker. His interactive installations offer great

inspiration for lighting designers, architects and all related professions! Supporting programme As in previous PLDC editions, the conference will be accompanied by an informative, inspiring and innovative supporting programme. The manufacturers’ exhibition from the partners in the industry is developing at a fast pace – to date almost 75% of the exhibition is already sold out!! The pre-convention meeting day is shaping up to be a full additional conference day: The Cities’ Forum will be inviting lighting designers, architects and city planners to gather and learn about latest developments. Partner Cities of PLDC will be presenting their ongoing and

Based on the evaluations provided by the Paper Reviewing Committee, 15 authors of self-running poster presentations have been selected by the Steering Committee to add additional value to the conference programme. The poster presentations are also classified according to the four conference tracks Professional Practice Issues, Lighting Application Case Studies, Lighting Application Research and Light + Culture. PLDC 2015 will offer a new component: Experience Rooms. These spaces are designed to allow attendees to become actively involved in specific activities, experience light and darkness, or play a part in ongoing research studies. The grand final of The Challenge will be held on Saturday, 31. October as

an official part of the PLDC programme. The finalists were selected during Round III of The Challenge at a mini-conference in Edinburgh at the beginning of February. Participants of The Challenge are young talents, some still students at renowned universities around the world, some newly qualified professionals who recently started working for established professional lighting design practices in the USA and Europe. As Iain Ruxton, lighting designer at Speirs and Major/UK summed up after the event in Edinburgh/UK: “The standard of the papers has been very high and it leaves me thinking the future of the profession is in good shape!” The following talents will be competing against each other in Rome: Team Brendan: Pernille Krieger/DK and Eik Lykke Nielsen/DK Team Emrah: Roslyn Leslie/UK Team Florence: Isabel Sanchez/E/ USA Team Iain: Stephanie Denholm/UK Team Tapio: Mahdis Aliasgari/IR/S CIBSE credits for PLDC attendance Continuing Professional Development is of utmost importance for young designers and established professionals and a long term commitment! CIBSE (Chartered Institution of Building Services Engineers) will be granting one credit per attended paper at PLDC this year.

2015 partnered by iGuzzini France Evening reception in Barcelona/E, September 2015, partnered by iGuzzini Spain More information and updates on the programme, as well as reports on past warm-up events can be found at An educated decision – the motto for PLDC 2015 is a clear announcement and appeal for more design to be evidence-based and to address and incorporate current research findings. Education in the field of architectural lighting design is the key to quality designs. Lighting design is an independent profession, and the scope of work of a lighting designer, plus the added value of working with a lighting designer, needs to be communicated to related professions, clients and end-users. However, new technologies and the scope they offer, as well as the latest research findings, demonstrate the need for more education on the part of the lighting designer him/ herself to ensure clients’ needs and forthcoming standards can be met. PLDC 2015 will address education on all these levels, taking the lighting design community’s efforts a step further and contributing towards all involved being able to make an educated decision in future! PLDC 2015 will mark a further step in the pursuit to officially establish the architectural lighting design profession. The chosen location for

this event is Rome, a city rich with culture, architecture, art. Culture, architecture and art will be the main topics for the conference and will offer a broad variety of focuses for presentations and discussions! About PLDC PLDC is organised by VIA Events, the Educational Events Division of VIAVerlag, publisher of the Professional Lighting Design magazine. Professional lighting associations and universities from around the world with Lighting Design programmes will be invited to partner the event. This high-quality network guarantees to spread the word further and to reach newcomers and professionals from related fields of practice. Based on the proven success of the PLDC concept, the convention will again be built around a three-day professional conference offering approximately 70 presentations given by high-profile speakers from the world of lighting design, architecture, research, city planning, daylight design and many other related professions. The convention will also include invited Keynote Speakers, a manufacturers’ exhibition, excursions, Experience Rooms, pre-convention meetings including a Cities’ Forum, social events, self-running electronic poster presentations, the final round of The Challenge, a student speaker competition conceived for the PLDC event, and a Gala Dinner during which the Professional Lighting

Design Recognition Awards will be given for outstanding achievements in Architectural Lighting Design. PLDC offers further and continuing education in the field of lighting design and the presentation of cutting-edge technologies.

SABIC plans to tap Indian lighting industry with innovative polymers


s a part of this plan, the Saudi Arabian company launches a range of plastic compounds for LED application at the recently held Light India exhibition LED manufacturing costs down Saudi Arabian petrochemical major Saudi Basic Industries Corporation (SABIC) is reportedly eyeing to tap the Indian lighting industry with its innovative materials which can meet the needs of electric appliance manufacturers and their customers. Lighting manufacturers are in constant pursuit of innovative materials and designs that reduce costs while maintaining design and performance integrity. “SABIC is catalysing these efforts with an expanded portfolio of materials for cost-efficient hybrid heat sinks, a component that is critical to the longevity of light-emitting diode (LED) lights,” said a SABIC press

release. With the addition of two new grades of Konduit compound, SABIC is bringing the solution that can enhance thermal management for customers at a cost that helps them maintain a competitive edge. Konduit PX13012 and PX11311U compounds, SABIC’s next generation of thermal conductive materials have inherent electrical isolation properties and excellent flame resistance. Innovative solutions using these new materials, as well as other technologies for the commercial, residential and outdoor lighting markets, were displayed at the Light India exhibition, held in New Delhi from September 18-21, 2014. The company claims that costefficient Konduit PX13012 and PX11311U compound grades deliver improved mechanical properties while keeping manufacturing costs down.

22 | March-April 2015 | lightexpress

“SABIC’s new Konduit compound grades will help our customers design light bulbs that can compete on design, useful life, and brightness, as well as cost. Unlike other appliance and electronics categories, in which consumers and endusers are willing to pay a premium for a better product, purchasing decisions in the lighting category are highly price-driven. As material manufacturers, we have an important role to play in building light bulbs that meet the demands of our customers, and our customers’ customers,” said Venugopal Koka, Director of Electrical and Lighting Marketing for SABIC’s Innovative Plastics business. On display at Light India was also ChromaLit Linear, a state-of-the-art LED offering developed by SABIC’s Innovative Plastics business in collaboration with Intematix Corporation, a US-based manufacturer of phosphor solutions for LED

lighting. By using Intematix’s remote phosphor technology and SABIC’s Lexan Lux resins, lighting customers can now achieve the energy efficiency and reliability benefits of LEDs, while also experiencing increased optical efficiency and better light uniformity - a critical factor for commercial environments. “SABIC is excited to have worked with Intematix to design a solution that successfully addresses a historic challenge with LED lighting used in commercial applications. In addition to being more efficient, the new LED system can be both extruded and injection moulded. Our collaboration and combined expertise in both material and LED technology has enabled the development of this solution that brings uniform lighting and potential system cost savings to an expanded set of LED applications,” said Koka.

Plastic bulb development promises better quality light US researchers say they have developed a new type of lighting that could replace fluorescent bulbs. The new source is made from layers of plastic and is said to be more efficient while producing a better quality of flicker-free light. What we've found is a way of creating light rather than heat� The new light source is called fieldinduced polymer electroluminescent (Fipel) technology. It is made from three layers of light-emitting polymers, each containing a small volume of nanomaterials that glow when electric current is passed through them. The inventor of the device is Dr David Carroll, professor of physics at Wake Forest University in North Carolina. He says the new plastic lighting source can be made into any shape, and it produces a better quality of light than compact fluorescent bulbs which have become very popular in recent years. Wake university researcher with light The new light source is said to be twice as efficient as fluorescent bulbs. "They have a bluish, harsh tint to them, " he told BBC News, "it is not really accommodating to the human eye; people complain of headaches and the reason is the spectral content of that light doesn't match the Sun - our device can match the solar spectrum perfectly. "I'm saying we are brighter than one of these curlicue bulbs and I can give you any tint to that white light that you want." Lighting accounts for around 19% of global electricity use A worldwide switch to low-energy

bulbs could save the output of around 600 power plants There have been several attempts to develop new light-bulbs in recent years - Light Emitting Diodes (LEDs) have come a long way since they were best known for being indicator lights in electronic devices. Over the past decade, they have become much more widely used as a light source as they are both bright and efficient. They are now often used on large buildings. Light not heat Another step forward has been organic LEDs (OLEDs) which also promise greater efficiency and better light than older, incandescent bulbs. Their big advantage over LEDs is that they can be transformed into many different shapes including the screens for high-definition televisions. But Prof Carroll believes OLED lights haven't lived up to the hype. "They don't last very long and they're not very bright," he said. "There's a limit to how much brightness you can get out of them. If you run too much current through them they melt." The Fipel bulb, he says, overcomes all these problems. "What we've found is a way of creating light rather than heat. Our devices contain no mercury, they contain no caustic chemicals and they don't break as they are not made of glass." Prof Carroll says his new bulb is cheap to make and he has a "corporate partner" interested in manufacturing the device. He believes the first production runs will take place in 2013. He also has great faith in the ability of the new bulbs to last. He says he

'India's LED lighting demand to rise by 40 percent'

The demand for light emitting diode (LED) lighting in India is expected to grow by about 40 percent per annum over the next five years, lighting solutions manufacturer NTL Lemnis said Wednesday. "I personally feel the LED market (in India) would grow by about 40 percent year-on-year basis at least for the next five year," global chief executive officer of NTL Lemnis Arun Gupta told IANS in an interview. The size of the current lighting market in India stands at around Rs.96 billion and the LED lighting industry's share is around Rs.10 billion, he added. According to the Association of Electrical Lighting Manufacturers in India (ELCOMA), the lighting industry in the country has been growing at nearly 17-18 percent annually over the past two-three years. Although the overall lighting market growth is going to be slower, the LED lighting market offers very high growth opportunity, Gupta said. The LED Industry is expected to touch around $500 million by 2015 in India. Within the segment, the demand for LED street lights and LED solar lights is expected to grow rapidly in coming years, Gupta said.

annual turnover of Rs.675 crore (2012-2013). Although households still prefer compact fluorescent lamps (CFL), the demand for LED lighting is increasingly rising in the commercial segment. The mining industry is expected to contribute to the growth of LED lighting in the coming years, according to the NTL Lemnis global CEO. The Indian LED lighting industry is likely to grow in the range of Rs.8,000-12,000 crore in the next five years, and NTL Lemnis is eyeing to capture a five percent market share, he said. According to a report by global consulting firm McKinsey, 70 percent of lighting in the world would be LED based by 2020. Currently, the number of LED buyers in the general lighting segment is low owing to high costs of such systems but the situation is changing rapidly, Gupta said.

Set up in 2012, NTL Lemnis is a joint venture company between NTL Electronics India and Lemnis Lighting, the Netherlands. NTL Electronics India Ltd. is considered as one of the largest manufacturers of lighting electronics in the world outside China. It has an 28 | March-April 2015 | lightexpress

City to Fit All Streetlights With Energy-Saving LED Bulbs The amber glow of the New York City streetlight is going away. In an energysaving effort, the city plans to replace all of its 250,000 streetlights with brighter, whiter, energy-saving, light-emitting diode fixtures in one of the nation’s largest retrofitting projects, Mayor Michael R. Bloomberg and the transportation commissioner, Janette Sadik-Khan, said in a news conference on Thursday. Enlarge This Image

Feeling For | An Eco-Lightbulb that Looks Better Naked Old-fashioned filament bulbs may cast a warm, flattering light, but their century-old technology leaves a substantial carbon footprint. What’s more, they’re in trouble with the law. A federal regulation passed in 2007 calls for the production of energy-wasting incandescents to effectively cease as of Jan. 1 of this year — though existing bulbs will remain on store shelves, and ambience-minded interior designers aware of the regulation have for several years been furtively stockpiling them. Last week, Congressional Republicans — apparently not fans themselves of the ghoulish glow of energy-efficient compact fluorescent (C.F.L.) bulbs — attached a provision to the new spending bill that eliminates funding for the law’s enforcement. Regardless of the fate of Edison bulbs, the British design studio Plumen is committed to reinventing the C.F.L. — which consumes 75 percent less electricity than a standard bulb — to please environmentalists and aesthetes alike. Its first bulb, a tangle of curvilinear tubes released in 2010, made it into the permanent collections of MoMA and the Cooper-Hewitt National Design Museum. Now, the company has released the Plumen 002 — a solid, sculptural form, inspired by the sculptures of Henry Moore and Barbara Hepworth — for pre-order on Kickstarter. Plumen’s creative director Nicolas Roope worked with the Texas-based neon artist Tony Greer to devise the mold-blown silhouette, the first of its kind in the energy-efficient category. The unique shape generates varying intensities of light throughout its contours for a nuanced, eye-pleasing effect. “Light is not like bread or beans; it’s magical, ethereal, there and not there,” Roope says. “We wanted to tease out that enigma, so you can never really grasp what’s happening under the skin.” And because the only thing worse than standard C.F.L.s’ clenched-spiral design is their grim, bluish cast, the 002’s glass has been tinted to a much more agreeable spot on the Kelvin scale. The result is a bulb that lasts through eight years of normal use without having to stay hidden behind a shade. 32 | March-April 2015 | lightexpress

The phasing out is part of the administration’s long-term plan to reduce its greenhouse gas emissions by 30 percent by 2017. Mayor Bloomberg described the switch as a “large and necessary feat” that will save taxpayers money and move the city closer to its sustainability goals. The project is also part of the Transportation Department’s plan for more environment-friendly operations, Ms. Sadik-Khan said. The news conference was on Eastern Parkway in Brooklyn, where lights have already been replaced, expecting to save more than $70,000 and nearly 248,000 kilowatt-hours a year in energy. Unlike standard lights, which last six years, LED bulbs can burn for 20 years before they need to be replaced, the administration said, and the project is expected to save $14 million a year in energy and maintenance costs. The project, which began as a pilot program in 2009, will be completed in three phases. The full removal will start in Brooklyn with 80,000 “cobraheaded” streetlights, with their sodium high-pressured bulbs, then move on to Queens and, eventually, the rest of the city. The city has already replaced some 3,625 lights along Franklin D. Roosevelt Drive in Manhattan; Eastern Parkway in Brooklyn, between Grand Army Plaza and Ralph Avenue; and along pedestrian paths in Central Park, where, Ms. Sadik-Khan said, passers-by noticed the change. “People tend to like them,” she said. “It’s clear. It’s bright. It really does a good job in providing fresher light.” The project is estimated to cost $76.5 million. The project is the first to receive financing through the Accelerated Conservation and Efficiency initiative or “ACE,” the administration said, a $100 million competitive program that the Department of Citywide Administrative Services created to expedite such sustainability projects. Lights along the city bridges will be financed by the Transportation Department, Ms. Sadik-Khan said

Why blue LEDs are worth a Nobel Prize Blue light-emitting diodes help create the glowing screens of mobile phones, computers and TVs and promises to revolutionise the way the world lights its homes and offices. That bluish-white light glowing from the screens of most new televisions, smartphones, laptops and tablet computers? It comes from light-emitting diodes, better known as LEDs. Many businesses light their work spaces with LEDs. More and more, LEDs light up outdoor street signs and traffic lights. Some homeowners have begun turning to this new form of lighting to illuminate their rooms. And most cars and trucks now use these same LEDs in their tail lights.

said, 'The LED lamp holds great promise for increasing the quality of life for over 1.5 billion people around the world who lack access to electricity grids.'

Three scientists have now won the 2014 Nobel Prize in physics for developing the technology that has made this lighting possible.

The question now that arises is can semiconductor chips, which have revolutionised the way we live, give us light? The answer today is, it can.

On Tuesday, October 7 2014, three Japan-born scientists -- Isamu Akasaki, Hiroshi Amano and Shuji Nakamura -- won the Nobel Prize in physics for the invention of blue light-emitting diodes -- a new energy-efficient and environmentally friendly light source.

Such chips for lighting are not made of silicon, which is used in electronics but more complex semiconductors, made of alloys of gallium, indium, arsenic, nitrogen, aluminum, phosphorous.

According to the Royal Swedish Academy of Sciences, the committee that bestows the honour, which includes a prize money of 8 million kronor (Rs 6.8 crore/Rs 68 million), when Nakamura, Akasaki and Amono 'produced bright blue light beams from their semiconductors in the early 1990s, they triggered a fundamental transformation of lighting technology.' Explaining further, the committee

It has been known since the turn of the century that some semiconductors emit light when a current is passed through them. However, it has taken almost a hundred years for technology to do it efficiently and inexpensively. The discovery and perfection of direct conversion of electricity into light has also led to the reverse that is the development of more efficient solar panels to convert light into electricity.

The first bright LEDs to be invented were emitting red, then orange and yellow light. However, attempts at producing green and blue LEDs were not very successful till a Japanese scientist Shuji Nakamura invented a bright blue LED and later white LED in the mid-1990s. Nakamura's work brightened up the whole field and intense activity ensued leading to fast growth. He worked hard with very little funding and repeated disillusionment for several years to come up with blue LEDs. The company he worked for at that time, Nichia is today one of the world leaders in blue and white LEDs and lasers. A few years ago, he moved out of Nichia and today, is a faculty member at the University of California at Santa Barbara. LEDs for lighting purposes have many advantages. They convert electricity much more efficiently into light than say incandescent bulbs or fluorescent lamps. In fact, 90 per cent of energy in incandescent bulbs is wasted as heat.

LEDs also last much longer -- up to 1,00,000 hours -- that is more than 12 years of continuous operation. Whereas in the case of incandescent lamps, they last for 1,000 hours while fluorescent lamps last for 10,000 hours. LEDs also consume less electricity, which is why batteries in a LED flashlight, for example, seem to go on forever. These make LEDs ideal if you are in a remote area on your own, camping or even in times of natural disaster. However, LEDs do, like with all technology, have some flaws and weaknesses. One the brightness of LEDs -- that is measured in Lumens per Watt of electrical power -- is still nowhere near the standard required for high brightness lighting. Secondly, the products are still expensive and lastly, the light is extremely bright in one direction hence, a LED light directed towards your work bench or a flashlight works well but if you try to light up your room with it then you end up using too many LEDs.

n energy harvesting switch which reacts to its environ ment without a need for energy. This solution developed by CHERRY is based on the principle of Energy Harvesting and does not require any wires. Energy Harvesting can be described as an ‘operation without any auxiliary energy’. Instead of generating auxiliary energy through an integrated energy source or adding it via an external energy supply, energy that is available in the surrounding environment or that is acting on the system is converted. Therefore an Energy Harvester generally speaking is an energy converter. The wireless RF switch system from CHERRY based on an energy harvester transforms the mechanical input energy of the actuation into

electrical energy, which then transmits, for example, a switching signal to a wireless receiver via RF electronics. The advantages of the system are that the switch can be placed anywhere without the need for any wires. Over its whole life cycle it will fulfill its function completely maintenance free and without any need to replace a battery. The RF switch is fed with different input parameters and is capable of reacting to its environment.CHERRY Industrial Solutions presents an energy harvesting wireless switch module for KNX-RF. In recent years the KNXstandard has developed from a cable-based twisted-pair approach and radio technology to a fully integrated radio technology with ETS configuration. The wireless switch module now even adds the energy harvesting aspect. The ready-to-assemble KNX-RF wireless switch module from CHERRY can directly be integrated into switches with customized control units or design-parts and requires no wires or batteries. It is designed for all switch series with a

standard inner frame of 55x55mm. The actuation of the switching unit produces enough electrical energy to transmit a complete KNX-RF ready protocol in S-mode directly to any KNX-receiver. There is no need for a gateway and the configuration is done via ETS as standard. The transmitter has a range of 30m in the 868 MHz band. The radio electronics can also be used in the 915 MHz band. The maintenance-free module has been optimized for a low actuation force and a low operation noise. Variants with a double rocker and two channels including a complete dimming function are currently being developed.

Nanoleaf partners with Stanjo to light up India Taking green from technology to lifestyle


reen-tech start-up partners with local distributer to shed light on how LED lighting technology can also become a lifestyle appeal

Nanoleaf Bloom, with a third, the Nanoleaf Gem, on the way; all of which are extremely energy efficient in nature, but were also designed with the tasteful consumers in mind.

When it comes to interior design, lighting has commonly been perceived as a piece of functional hardware, a category that has generally placed its focus on technological innovation. And while lighting technology has come a long way over the years, from incandescent to fluorescent, to the latest in lighting innovation, LEDs, the category has never really challenged convention outside the boundaries of efficiency. Nanoleaf, a creative green technology start-up, has partnered up with local distributer, Stanjo, making its way into India to showcase some of their creative lighting products, ones that take efficient lighting beyond technology.

“We want to inspire people to adopt more energy efficient technology.” Says co-founder and CEO, Gimmy Chu. "The best way to do that is by making products that are not only better in functionality, but also more aesthetically desirable.”

“We are first and foremost a green technology company, and we make products that challenge the standards in energy efficiency. However, in order to make an impact on our environment, we understand that technology alone wouldn’t cut it. To make a difference, we need to get that technology into more hands.” Explained Nanoleaf co-founder and COO, Christian Yan, “That is why when it comes to design, we put people first.”

The Technology The Nanoleaf One and the Nanoleaf Bloom are a pair of technological marvels. With their custom LED packages, the pair boasts 133 lumens/ watt and 120 lumens/ watt respectively. Beyond pushing the boundaries on energy efficiency, they also offer quality light with a CRI (Color Rendering Index) rating over 80. Paired with their efficacy, they offer the best quality to efficiency ratio that you can find in the category.

So far, Nanoleaf has released two ultra-unique looking LED bulbs called the Nanoleaf One and

The Looks Who said light bulbs can’t also be a part of the home decor? The

The Brand Nanoleaf has a fun eccentric and refreshing personality. The brand represents thinking outside of the box, a desire to do good for the world, and looking good while doing it. Nanoleaf’s brand personality puts a face on an otherwise faceless industry, and befriends the consumers in a genuine way.

Nanoleaf One and Nanoleaf Bloom bulbs have an edgy, abstract feel to their instantly memorable appearances. The bulbs are produced through an origami-like process where cut outs of PCB board with all the circuitry in place are folded into the final dodecahedron shape. For those who prefer something a bit more conventional, the Nanoleaf Gem adds a more elegant touch to the dodecahedron shape with a frosted glass exterior, making it an exceptional blend of style and science. The Utility Nanoleaf light bulbs emit high quality light that is also romantic in nature. Fluorescent lighting has been the lighting of choice in most cities around the world in the past few years because of they are more energy efficient than traditional incandescent bulbs. However, their light quality is dreadfully undesirable, and makes any room feels like hospital. Nanoleaf bulbs on the other hand produces a warm light colour that helps rejuvenate the stressed minds and injects some sense of comfort and happiness in its place. The Nanoleaf Bloom is also the first dimmable light bulb that does not require a dimmer switch. It uses a custom controller chip to translate regular light switch motions into dimming commands, and brings the convenience of dimming to every ON/OFF light switch. This newly added flexibility to dimming allows people to have it bright when they

need, and dim it down to a cozier brightness when they want. The Nanoleaf Bloom not only cuts down significantly on energy consumption, but also allows people to enjoy different ambience of light for all of their life’s moments. Do good. Look good. Feel good. Lighting may have traditionally been considered a purely functional piece of hardware, but with impending arrival of Nanoleaf and its plans to bring manufacturing to Hyderabad, it’s undeniable that interior designers and homeowners in India will now have one more thing to play around with.

About Nanoleaf Nanoleaf is a green technology startup with a mission to create a more sustainable future. Founded in 2012 by University of Toronto graduates Tom Rodinger, Gimmy Chu, and Christian Yan, Nanoleaf is a family of fun, creative, and passionate geeks committed to developing energy efficient products that promote and encourage a more sustainable lifestyle. Green at heart, with people in mind, Nanoleaf combines planetfriendly technology with peoplefriendly designs to offer greener products that don’t compromise on personal benefit, products that ultimately lead to a better and brighter world.

LED lighting - the future! Q. I’m replacing the lights in my home before putting it on the market. Is it better to install LED fixtures, if it’s true that incandescent bulbs are being phased out? A. From a sales perspective, high-efficiency LED lighting is a nice perk, said Ron Lense, an associate real estate broker at Douglas Elliman in Manhattan. But it may not significantly affect your selling price. “Everybody loves going green,” he said. “They just don’t necessarily want to pay a lot of extra money for it.” LED lighting is becoming increasingly popular, he said, and if you install it now, “you’ll be ahead of the curve.” Just be cautious about the fixtures you choose, “because this is emerging technology that is quickly changing.” If you buy fixtures with technology that is outdated by the time you sell your home, he said, “you’re spending money that might not come back.” That’s one of the reasons that Doug Russell, a lighting designer who owns the Lighting Workshop in Brooklyn, usually recommends buying standard incandescent fixtures and adding LED bulbs as a retrofit. “I feel better about putting today’s best LED technology into an incandescent downlight as a retrofit,” Mr. Russell said, “because I know that in three years it’s going to be obsolete and I can unscrew it and put in the latest technology. If I put in a downlight that’s an integrated LED, you’re stuck with it.” And incandescent bulbs aren’t being phased out entirely, he said. Under new legislation, “there are efficiency standards that lamps need to meet,” so some types of traditional incandescent bulbs are disappearing, he said. “But there will always be replacements for them.” The qualities of traditional 100watt incandescent bulbs, for example, are being emulated by 72-watt halogen bulbs, which are more energy efficient. But when you are picking out LED bulbs, Mr. Russell has a recommendation: “There are a lot of really bad LED-retrofit household bulbs out there that will make your home look terrible, because the color’s awful.” Some of his preferred replacements are made by Philips, and the best ones tend to be a little more expensive, he said. But they “have great color, are really warm and flattering, and are dimmable.” Which brings us to a potential complication of replacing an incandescent bulb with an LED model: you may not be able to control it with a standard dimmer, and you may have to replace your dimmer with one that is LEDcompatible. Mr. Russell said that there are a few exceptions to his advice about avoiding fixtures specifically designed for LEDs. Under-cabinet lighting is one. “Under-cabinet lighting in kitchens is a great application for LEDs,” he said, “because you bring the light source close to the task and don’t increase heat loads” — welcome news to anyone who has halogens that get so hot they occasionally melt the contents of the cabinet above. 42 | March-April 2015 | lightexpress

Three Physicists Share Nobel for Work on LED Lights >>>

44 | March-April 2015 | lightexpress


hree physicists have been awarded the Nobel Prize for revolutionizing the way the world is lighted. The 2014 physics award went to Isamu Akasaki and Hiroshi Amano of Japan and Shuji Nakamura of the University of California, Santa Barbara, for “the invention of efficient blue light-emitting diodes, which has enabled bright and energy-saving white light sources.” The three scientists, working together and separately, found a way to produce blue light beams from semiconductors in the early 1990s. Others had produced red and green diodes, but without blue diodes, white light could not be produced, the Royal Swedish Academy of Sciences said on Tuesday morning in its prize citation. “They succeeded where everyone else had failed,” the academy said. Their work has spurred the creation of a whole new industry. The committee that chose the winners said light-emitting diodes, or LEDs, would be the lighting source of the 21st century, just as the incandescent bulb illuminated the 20th. The three scientists will split a prize of $1.1 million, awarded in Stockholm on Dec. 10. Dr. Akasaki, 85, of Meijo University and Nagoya University, and Dr. Amano, 54, of Nagoya University, are Japanese. Dr. Nakamura, 60, is American. Awakened by a phone call from the Swedish academy, he described it in a news conference as “unbelievable.” In its announcement, the academy recalled Alfred Nobel’s desire that his prize be awarded for something that benefited humankind, noting that one-fourth of the world’s electrical energy consumption goes to producing light. This, it said, was

a prize more for invention than for discovery. Frances Saunders, president of the Institute of Physics, a worldwide scientific organization based in London, agreed with those sentiments. Noting in an email statement that 2015 is the International Year of Light, she said, “This is physics research that is having a direct impact on the grandest of scales, helping protect our environment, as well as turning up in our everyday electronic gadgets.” In Africa, millions of diode lamps that run on solar power have been handed out to replace polluting kerosene lamps. For the same amount of energy consumption, LED bulbs produce four times the light of a fluorescent bulb and nearly 20 times the light of an incandescent bulb. LED bulbs are also more durable, lasting 10 times as long as a fluorescent bulb and 100 times as long as an incandescent bulb. Light-emitting diodes are already ubiquitous — in pockets and purses, in smartphones, as well as in televisions, lasers and optical storage devices. And their future is vaster still. “The LED lamp holds great promise for increasing the quality of life for over 1.5 billion people around the world who lack access to electricity grids,” the Nobel committee said. “Due to low power requirements, it can be powered by cheap local solar power.” The work rewarded on Tuesday was the latest step in an evolution that began with Thomas Edison’s burning out light-bulb candidates in his Menlo Park laboratory in the late 19th century. Incandescent bulbs use electricity to

produce heat in a glowing filament that emits a comparatively small amount of light; fluorescent lights use a gas. Light-emitting diodes are based on the same quantum magic that gave birth to computers, smartphones, transistor radios and all other electronic devices. The diodes are no bigger than a grain of sand and consist of sandwiches of semiconducting materials. When an electric field is applied, negative and positive charges meet in the middle layer and combine to produce photons of light. The color of the light produced depends on the type of semiconductor. Nick Holonyak Jr. of the University of Illinois, who invented the first redlight diode in 1962, has called the LED the “ultimate lamp” because “the current itself is the light.” Red- and green-emitting diodes have been around for a long time, but nobody knew how to make a blue one, which was needed for blending with the others to create white light. The amount of information that can be packed into a light wave increases as its wavelength shortens, making blue the color of choice for conveying information. That is where the new laureates, working independently, came in. The key was to grow high-quality crystals of gallium nitride, a semiconductor for producing blue light — a process that had frustrated researchers. Dr. Akasaki first tried to grow the crystals in the late 1960s as a young research associate at Matsushita Research Institute in Tokyo. It was not until 1986 that he and Dr. Amano, who was then his graduate student, succeeded in growing high-quality crystals on a layer of sapphire coated with aluminum nitride, and found out their

properties were enhanced when they were scanned with an electron beam. The royalties from their work subsequently funded the construction of a whole new research institute, the Nagoya University Akasaki Institute. Dr. Nakamura, then at the Nichia Corporation, a chemical engineering and manufacturing company, succeeded in growing his own crystals, improving on the other two scientists’ method. In 2006 he was awarded the Millennium Technology Prize of one million euros (about $1.3 million) for inventing the first efficient blue-light laser, opening the way for things like Blu-ray players. Dr. Nakamura left Nichia in 1999 to join the University of California, Santa Barbara. Two years later, in a shocking challenge to Japanese traditions of subservience, he sued the company for 20 billion yen, $193 million at the time, saying he deserved a share of royalties for his inventions. Nichia had given him an award of 20,000 yen — about $200 — for his contributions to the company. A court awarded him the full amount, but the company appealed. In 2005 he and the company settled for a payment of 843 million yen, or about $8.1 million. As is often the case with Nobel Prizes, not everybody was happy on Tuesday. The prize can be awarded to no more than three people, and Dr. Holonyak expressed dismay that various American scientists who had laid the framework were left out. “We’re always tugging and pulling,” he said in a telephone interview from Illinois. “Nobody is smart enough to know all this.”

German company invented

The Dancing LED Traffic Light Waiting the red light is undoubtedly a suffering thing, so there are many people run the red light. Recently, the German company BBDO engages in a very interesting concept with Smart company jointly, this concept is called “The Dancing Traffic Light”. It makes the original rigid red villain alive suddenly, and dancing in front of you constantly, when you watch the dancing, tens of seconds passed unknowingly. Some people may ask: “If it is always the same dancing, everyone will look tired soon, right?” Actually not, the highlight of the concept is – in fact, the dancing is by real person. There is motion capture room not far from this LED traffic light, anyone can go in and show their dance in front of the sensor, the red light villain will reflect dancers’ movements, also dancers can observe the audiences reactions through camera. The dancers won’t feel embarrassed because we can not see who is dancing. It is said that this dance lights attracted more than 81% of the pedestrians successfully, and they stopped and did not run the red light.

Philips and Ericsson to Use Streetlights to Expand Cellphone Coverage user consumed 1.2 gigabytes of data a month over cellular networks, nearly double the average amount used in 2012, Chetan Sharma, a consultant for wireless carriers, estimated. In response, operators like AT&T and mobile network infrastructure providers like Huawei of China are looking for ways to bolster cellphone coverage. The European technology companies Ericsson and Philips unveiled their own solution to this problem, a project that combines city street lighting with mobile phone infrastructure. The companies will incorporate cellphone antennas into energy-efficient LED streetlights that can be placed in parts of cities where carriers want to increase their network coverage. By tapping into cities’ streetlights, operators will be able to expand their networks in urban areas where it can be difficult to get zoning approval for large and cumbersome infrastructure like cellphone base stations. Philips and Ericsson say their plan offers cash-strapped city governments a new source of income in the form of payments from carriers that want to rent out space on the streetlights. The two companies added that the LED streetlights offer cost savings of about 50 percent compared with traditional lighting.

Cellphone operators worldwide are struggling to keep pace with growing demand for mobile data.

“This is the best way to strengthen mobile networks,” Hans Vestberg, Ericsson’s chief executive, said in an interview. “We can’t get any big sites for mobile equipment anymore. This allows us to reuse existing infrastructure.” The two companies have been working with Verizon Wireless on a

pilot project in the United States over the past year. Ericsson and Philips now want to roll the project out globally and are in talks with cities in the United States and Europe about how to modify the streetlights to meet local needs. They declined to say with which cities they were in discussions. “This is a concept that has resonance in all parts of the world,” said Frans van Houten, Philips’s chief executive. “You can’t have a single design for all cities. The look and feel of the streetlights are very important.” As carriers like Deutsche Telekom of Germany and China Mobile spend billions of dollars to upgrade their networks, analysts said, telecommunications companies have sought to work with other industries and local governments to find new locations for mobile phone infrastructure. The partnerships, which propose putting cellphone antennas in new places like bus stations or trash cans, offer a chance to reduce costs, as multiple companies would share the price of installing highspeed mobile data equipment. The deals would also give carriers the ability to gather additional information about customer habits, analysts said. With expanded coverage through cellphone equipment on streetlights and in other city infrastructure located near customers, operators can get a better picture of how people use their networks. “Collaboration can lead to new business models,” said Sylvain Fabre, a telecommunications analyst at the research firm Gartner in London. “It offers carriers the chance to get real-time data on consumers. If you can get close enough, you can get real insights into users’ activities.”

AS LED INDUSTRY EVOLVES, CHINA ELBOWS AHEAD GUANGZHOU, China — A year ago, China’s light-emitting diode industry seemed like a case study of industrial policy gone awry. Hundreds of factories built all over eastern China, often with lavish clean energy subsidies from state-owned banks and local governments, were operating at half capacity. The share prices of LED manufacturers were plunging. Now demand is surging, and the Chinese manufacturers suddenly find their factories running at full tilt, churning out LEDs faster and cheaper than global rivals. With a price war underway, the Chinese are taking share from top players in the United States, Europe and Japan, the industry pioneers that made crucial technological breakthroughs, and from Taiwan and South Korea, previously the leaders in low-priced LEDs. For some in the United States, the Chinese expansion has uncomfortable echoes of the solar panel and wind turbine industries, in which China went from a bit player to global leader through a combination of extensive government subsidies and lowinterest loans from state-owned banks. “LED lighting could see itself become the next solar, wind or other future opportunity that the U.S. will have given away by failing to address Chinese industrial policies and unfairly traded products,” said Michael R. Wessel, a member of the U.S.-China Economic and Security Review Commission, a government advisory panel. Such industries have been at the center of increasing trade frictions between China and the United States. SolarWorld, a solar panel maker that complained to the American government about what it considered unfair advantages for Chinese competitors, was later the victim of a cyberattack by Chinese military officials, according to a recent indictment by the Justice Department. Yet LEDs represent a far more complex story than simply another industry that Western companies created and then ceded to Chinese rivals — one reason the trade issues may not play out in the same way. The industry, for instance, is highly segmented. Chinese manufacturers are strongest in the low-wattage LEDs used for television and cellphone backlights as well as for fairly dim lamps, equivalent to 40-watt incandescent bulbs. Western companies are retaining market share for brighter, higherwattage equipment with bigger profits. Many Chinese producers also have a poor and worsening reputation for quality, which may hurt them in the long term. CHINA ’S RISE REFLECTS THE INDUSTR Y ’S CHANGING D YNAMIC S. CHINA’S DYNAMIC In the last year, LEDs have finally begun to rapidly gain traction in the global lighting business. American, European and Chinese regulators have put in effect energy-efficiency rules that phase out the use of incandescent bulbs. Big multinationals that make light bulbs like Philips, Osram and General Electric 50 | March-April 2015 | lightexpress

have responded by embracing lightemitting diodes, which use one-fifth of the electricity of incandescent bulbs and half the electricity of fluorescent bulbs. Environmentalists have applauded. Lighting accounts for about 6 percent of the world’s emissions of greenhouse gases, and LEDs have the potential to steeply reduce them. For consumers, the shift has been good. Prices have fallen by nearly half in the last year for low-end, low-

wattage LEDs made in China, and by 15 to 20 percent for the higherwattage versions made elsewhere, buyers and manufacturing executives said. With significant capacity, Chinese manufacturers could quickly increase production to meet the demand. Alice Tao, a lighting analyst at IHS Technology, a global consulting firm, estimated that very low prices had allowed Chinese companies to capture about 30 percent of the global market. That gives them the biggest share ahead of Japan, South Korea, Germany,

Taiwan and the United States, which share the rest of the market in fairly even proportions. But quality is a concern as China floods the market. Instead of lasting a decade like well-made LEDs, the low-priced LEDs occasionally burn out after less than a year, large buyers warn. More commonly, they start emitting strangely tinted light that may leave a room looking slightly pink, a little bit green or even what is known in the lighting industry as a “rainbow sherbet” palette of colors.

“What is going down is consistency — you just don’t know if you’re going to get the life span that they promise,” said Benjamin Carson, the owner of an Australian sign company that uses LEDs to make outdoor business signs. Mr. Carson said that American-brand LEDs typically cost a third more than the Chinese LEDs that he buys. But he is considering a switch to American LEDs anyway because too many signs with Chinese LEDs ended up with burned-out or oddly colored sections after less than a

year. Other buyers are even more cautious. “We do not buy Chinese LEDs,” said Mike Pugh, the procurement director at Xicato in San Jose, Calif., a large provider of indoor lighting systems for retailers and hotels. “We just can’t take that chance.” Xicato instead buys LEDs from multinationals like Cree of Durham, N.C.; Philips Lumileds, based in San Jose, Calif.; and Osram Opto Semiconductors of Regensburg, Germany. The Chinese industry, with heavy

debts from an earlier spasm of investment, is still largely relying on factory equipment purchased from 2009 to 2011. But with sales growing fast, Chinese companies started ordering considerable new equipment from Western suppliers early this year, which could improve their reliability.

water supplies. Despite such issues, the LED industry is part of China’s broader push into clean energy. Threequarters of China’s electricity still comes from burning coal, which contributes to severe air pollution as well as global warming.

As with many fast-growing Chinese industries, there have also been China’s clean energy efforts are a environmental problems. Wang Wei, the major source of job creation.

resin. She earns $500 a month plus medical benefits and free food and lodging in an air-conditioned dormitory where employees sleep four to six in a room. “I like the recreation center here best,” she said, looking up from her microscope. But hanging over the LED industry have been trade frictions in the solar panel industry, which uses many similar technologies. The United States and European Union have both accused the Chinese government of violating global trade rules by providing export subsidies for solar panels, which China denies. In the years after the global financial crisis in 2008, the solar and LED industries in China received huge loans at low interest rates from state-owned banks following directives from Beijing to lend to green energy projects. “There are subsidies — it’s on the bank loans,” said Meng Zhaochun, the general manager of Shenzhen APR Corporation, a Shenzhen-based manufacturer of important LED components. China is now following the Obama administration’s example by encouraging greater domestic demand for energy-efficient lighting and moving away from subsidies. If domestic demand rises, it is harder for foreign governments to challenge past subsidies as trade violations. Many Chinese companies are struggling to make a profit. If state-owned banks stop financing the Chinese industry with low interest rates, consolidation may be inevitable. “There are too many Chinese players in this market and the price competition is very fierce,” Ms. Tao said. “Most of them can’t make a profit and it’s difficult for them to survive.” Even as Chinese manufacturers gain worldwide market share, their issues may only mount. The frenzied competition is still prompting many of them to cut corners, said Li Junfeng, a senior Chinese energy policy planner. “The problem,” he said, “is too many manufacturers with very low quality.”
