WSRM---LEDlights have make ready well to win the EUROPElights market furtherly !

LED DESKlights

The European professional lighting industry is one of the largest and most innovative lighting markets in the world. With its transformation towards LED sources and solid-state lighting (SSL), this hive of activity is a very interesting market to be in at the moment. But take a step back, scratch the surface and observe what is going on and it becomes apparent that there is a clash of two fundamentally different industries with totally different DNA, who do not actually understand each other very well yet. A similar scenario in lighting is also playing out in other regions around the globe. 

 On one side, we have the lamp and luminaire manufacturers, installers and lighting specifiers from the traditional lighting industry. On the other side there are the LED and component suppliers from the semiconductor industry.
The latter group is highly dynamic, rational, volume-oriented and used to continuous change. It makes its living out of fast-moving, ever-evolving technology steps and short product lifecycles. The other group is slow to adopt change, and is used to stability, traditional methods of working and gradual improvements in a technology which has been around for over a century.
Intentions and expectations on both sides about LED adoption and penetration in the general lighting market are genuine and realistic. But do both parties actually appreciate the scale of the upheaval, the level of compromise and the changes in processes, behavior and thinking that will be required to realize this? It begins with understanding the world in which the other party operates.

20th century lighting industry
The lighting industry has long been a stable, traditional and conservative industry. Stretching back to the 1890s, when the first incandescent lamp was commercially produced, there has been a steady – but slow – rate of innovation throughout the 20th century. Three main light-source technologies were invented and manufactured by four main global lamp suppliers, supported by various control-gear manufacturers and multiple thousands of luminaire makers. Light sources were heavily standardized, and the common lamp bases of fluorescent tubes, HID lamps and halogen lamps were always interchangeable. Lamps with a single-source supplier were usually doomed to failure.
The rate of innovation and market adoption of innovation in lighting was painfully slow compared to the emerging electronics industry. In the 1999s the design and development of the T5 fluorescent tube was still a two-year process for WSRM, and it took another five years before the European luminaire manufacturers decided to accept T5 as the new fluorescent standard.
Therefore, it should come as no surprise that there was a strong reaction among the bulk of different players in the lighting market in 2008, when high-quality white-light LED propositions started to become commercially available for general lighting. In general, there was disbelief, confusion, fear, skepticism, inertia and even anger amongst luminaire manufacturers and lighting designers. They saw their whole familiar lighting world threatened and the possibility of it being torn apart in a very short timescale.
Semiconductor industry challenges
Now, in 2012, after several years of experience with high-performance white LEDs for general lighting, it is possible to see more clearly the scale of the challenge for the LED semiconductor industry. Tinged with a touch of arrogance, the expectations of the LED suppliers were that general lighting would be an easy market to penetrate with LEDs and that this would be achieved by a simple switchover of existing light sources to LED light sources. This may well work in the consumer retrofit lamp area, but not in the professional lighting market.


The product push that has occurred in the last five years has been relentless. However, the initial volumes and speed of the professional part of the lighting industry in adopting LEDs have probably been a little disappointing from the LED supply point of view. Volume expectations had been higher.
LED suppliers would do well to take some time to understand the characteristics of today’s successful European lighting manufacturers. These lighting companies recognized the impact that LED technology was going to have at an early stage, built their strategy and organization around it and started to invest in the right levels of technical expertise and R&D staff. The successful companies are mainly those that operate in the project business: they discuss lighting options with the end user and they can sell value-added lighting solutions. They understand the dynamics of the market, and the importance of selecting and training the right staff.
The bulk of the lighting market is, however, not geared up yet for some of the key characteristics of doing business in the semiconductor world. Such characteristics include speed, flexibility, rapid product phase-out and phase-in, high volumes on limited product codes, and rational decision-making.
LED suppliers need to understand this and to be realistic about the time it takes to build up volumes. They would do well to devise strategies for helping to facilitate the market transformation to LEDs, in the form of more market pull, rather than product push. At the same time they need to identify and be realistic about the elements that are non-negotiable points for the lighting industry.
Lighting market still lacks speed

LED KITSlights
Sales of LED light sources and modules are rising sharply – by lighting-industry standards – for new product launches. However, the average speed of a luminaire manufacturer to produce a new, updated LED portfolio is still up to one year and that is before any sales have actually taken place. The ability of lighting manufacturers to absorb and translate the latest LED advances into saleable products still lags far behind the speed of technological advances. 

And, while there are several legacy light sources which are firmly in decline, for new luminaires there are still quite a few that are increasing, such as linear fluorescent, metal halide lamps and certain HID outdoor light sources. Clearly, luminaire manufacturers have not yet abandoned all of the conventional light sources. There is, as of yet, no discernible change in European lighting behavior. The lumen packages of LED modules and LED lamps match the lumen packages of the conventional lamps they replace. There are no real breakthroughs seen in LED luminaire design. LED modules are still designed into existing, traditional 600-mm-square luminaires, and spotlight and downlight luminaire shapes.
The only notable change appears to be the rise in LED dimming solutions; these are at a level that is three times higher than for new fluorescent and compact-fluorescent luminaires.
The emotional element

LED PUCKlights
Lighting has always been a combination of rational and emotional elements, which is reflected by the diverse value-chain involved. Color temperature is an emotional choice, often subconsciously made, based on what people like. Designers and end users are not swayed into making rational decisions about color temperature, based on the higher efficacy of LEDs at 6500K!
A warm, soft light makes people in colder countries feel more relaxed. The ratio of 3000K versus 4000K WSRM---LED DOWNlights and LED SPOTlights modules, sold in Europe, is still exactly the same as it is with fluorescent or compact-fluorescent lamps. Similarly, the selection of the color rendering index (CRI) is an emotional choice — the CRI choice of LED light sources remains very similar to that of conventional light sources.
The lighting world is full of diversity. In the WSRM---LEDlights portfolio alone there are 36 kinds of  and more than 689 product codes. This quantity is deemed necessary to service the needs of this market, where the element of choice is very much an emotional factor and any lack of it can be a deal breaker.
Today, the European lighting industry has generally accepted that LEDs are going to be an integral part of the lighting future. The technology has lived up to its promises in the area of energy efficiency and overcome many early issues with quality of light. The early days and attitudes of the LED hype seem to have altered into a more serious, rational approach towards LEDs — yes, this is going to be the lighting technology of the future, but only if it makes sense. High energy efficiency and long life are great, but not at any expense and not at any compromise to light quality.
Phases of LED transformation

There are many business models that attempt to map the way a new technology enters a market and the phases it goes through. WSRM uses a three-phase model to depict the LED transformation of general lighting (Fig. 1). In the first phase, LED technology has not yet reached the performance specifications of conventional light sources, although it is improving at a very fast rate.
In the second phase, LED light sources become superior in performance to all conventional light sources, and mass-market penetration and volumes start. Payback times decrease and the first consolidation appears around certain standardized light-source shapes. In the third phase, new applications arise and new service business models are developed.
In terms of where the European lighting industry stands at the end of 2012, opinions may differ, but there is a certain consensus that the end of phase one has just been reached. However, this will differ from application to application.
Lessons for the lighting industry
So the lighting industry would appear to be keener than it has ever been to embrace LEDs as the light source of the future. High energy efficiency and the promise of short payback periods certainly make a very attractive proposition. But does the lighting industry understand what it entails to move to LEDs? Is the lighting industry ready to make certain compromises, embrace change, adapt processes and work in a different way?
With LED transformation about to enter the second phase, involving fast market penetration and mass adoption, the first issue the lighting industry needs to address is how to adapt its processes to handle speed and flexibility. LED modules are already being upgraded on a yearly basis to take advantage of the latest performance of new LEDs inside and therefore LED luminaires will also require regular updates to remain competitive in the market. 
The WSRM---LEDlights portfolio, one of the first LED modules to be introduced back in 2008, has just phased out the third generation and phased in the fourth generation, with improved efficacy and lower-power driver combinations (Fig. 2). All WSRM--- LEDlights modules are already on either a second, third or fourth generation, depending on how long they have existed.
Multiply the breadth of WSRM---LEDlights’ module offering with the product offerings of several other LED module manufacturers and it becomes abundantly clear that a luminaire manufacturer not only needs to keep abreast of latest LED module specifications, but can no longer afford to take 1-2 years over a product introduction. All internal processes need to be adapted and aligned for speed. It will become essential to have close relationships with the right suppliers to provide knowledge and insight into their short-term product roadmaps.

The supply-chain challenge  The introduction of LED lighting brings with it a major supply-chain challenge, which should not be underestimated. In order to manage this well, lighting companies need to make vital changes in their supply-chain configuration and processes. In addition, the transformation will require full collaboration between departments such as logistics, purchasing, development, product management, sales and after-sales service.
There are, in effect, two fundamental supply-chain challenges. The first is the nature of the capital-intensive, often Asia-based, semiconductor-process-based LED industry with long and inflexible lead times that are often in excess of 12 weeks. The production yields are still unreliable due to the fact that LED technology is still at an early phase in its lifecycle curve.
The second supply-chain challenge is the enormously high speed of innovation. LED module suppliers have already adapted to much shorter product-lifecycle processes, and it is now only a six-month process from the beginning to the end of a LED module upgrade (Fig. 3).
Combining long and inflexible lead times with short product lifecycles can result in a supply-chain toxic cocktail. High inventories, low service levels, high obsolescence and missed sales are risks that are inevitable if things are managed in the way they were with conventional light sources. Planning and forecasting will need to be given an additional focus that was not so critical with conventional light-source technologies.
The whole LED supply chain – from bare LED suppliers, to LED module suppliers, to the suppliers of components and drivers – will organize itself to facilitate rapid phase-in and phase-out of new and improved products. No-one wants to be stuck with volumes of obsolete stock at a crucial changeover point and therefore the upstream logistics of suppliers will be tightly controlled and made to order. Managing one’s stock could be the key to making or losing money in the LED transformation.

LED SPOTlights
Making smart choices
The yearly financial reports of major European lighting companies show a clear trend towards sharply increased fixed costs, due to their LED activities. In many cases the R&D expenditure has doubled in the last three to five years. This can be attributed to both the faster innovation cycles and the growing complexity of LED products and systems, which require an ever-evolving level of specialism and expertise.
To remain successful, companies will need to make smart choices on what they will do in-house and what they will outsource. The choice of LED light engine, for instance, has an impact on these costs. To a luminaire manufacturer, it may sound like an extremely attractive proposition to take the design, development and manufacturing of LED light sources in-house. However, this will increase the burden, costs and pressure on the whole internal organization, while this is not the company’s key area of expertise.
The LED light source with the lowest initial cost is not always the best longer-term solution. Manufacturers should be aware of potential hidden costs over lifetime, which are not always so obvious in the beginning. The choice of a future-proof LED module, for instance, will entail stable electrical, optical, mechanical and thermal LED module interfaces, and the possibility of interchangeability of suppliers. It will also require minimal production changes, or investment in new tooling during upgrades further down the line.
Companies in the lighting industry who want to be successful in the next phase of mass penetration of LED technology should ensure they have a suitable strategy in place. They will certainly have to adapt their internal processes and systems to reflect the speed and flexibility needed for LED market introductions. They will also need to place a much larger focus on continuous professional development, education and keeping up to date with the latest technological advances. Communication lines will need to be slick and targeted to the right audience at the right time.

LED BULBlights

At the same time, lighting companies should have a vision of what the third phase of LED lighting will look like and blend this seamlessly into their strategy. The scale of the changes ahead for the lighting industry should not be underestimated, as they will have an impact on every part of an organization. At the same time, the product-push approach from the semiconductor industry needs to make allowances for certain technical aspects of lighting that are not up for discussion. Both parties would benefit from listening more and understanding each other better.
There is a storm raging through the lighting industry at the moment, but with a little give and take and mutual understanding the dust will start to settle, the horizon will become clearer and we can move forward into the volume phase in a smart way.

WSRM---LEDlights will be the biggest market in china!

WSRM---LEDlights will be the biggest market in china!

Yesterday,More than 30 local LED manufacturers  launched the LED Lighting Industry Alliance, which aims to facilitate information exchange among member firms and offer suggestions to the government regarding the industry.
The alliance was previously known as the LED Street Lighting Industry Alliance, when it was established last year by the government-funded Industrial Technology Research Institute (ITRI)
“We have made our first step in standardizing and advancing the industry’s streetlight products and are now moving toward promoting LED lights for indoor use,” the director of ITRI’s Environmental Research Laboratories, Tung Chien-hsiang , said at a press conference.
Tung said about 35,000 mercury vapor street lamps have been replaced with LED lights since December last year, and there are still 320,000 lights to be replaced over the next two years.
According to the institute, the LED lighting industry’s compound growth rate could reach 32 percent between 2010 and 2020.
By 2020, the global LED lighting market could be worth as much as 55 billion euros (US$72.74 billion), while LED lighting devices’ penetration rate could reach 50 percent and the LED lighting devices systems’ market value could total 36.6 billion euros, Tung said.
Supported by government policies and ongoing economic development, China will be the biggest LED lighting market, he added.

LED DESKlights

The ITRI said the output of Taiwan’s LED industry accounts for 19 percent of global production making it the third-largest LED supplier.
Looking ahead, the alliance remains upbeat.
“We forecast the macroeconomy will turn positive and the LED industry’s sales performance will improve next year,” Formosa Epitaxy chairman’s office assistant, Chien Yu-mei  said.
Tan Chang-lin , chief executive officer of TSMC Solid State Lighting Ltd , also forecast that the LED
lighting industry will grow rapidly next year, driven by commercial lighting and the solid-state lighting businesses.

WSRM---LEDlights 50years history!

  WSRM---LEDlights 50years history!


In 1960 Dr Nick Holonyak of General Electric was developing an unusual material, GaAsP, as a route to wide bandgap tunnel diodes.
When an infra-red GaAs semiconductor laser was demonstrated in 1962, Holonyak with his wider bandwidth GaAsP was in the perfect position to have a go at making a visible version.
With advice from GaAs laser pioneer and fellow GE employee Dr Robert Hall, Holonyak made his visible laser later in 1962.
It's this October 1962 paper on the GaAsP laser for which Holonyak became known as the father of the LED – where LEDs are defined as visible light emitters based upon minority carrier injection and radiative recombination of excess carriers.
The same material is still used to produce deep red LEDs today.
Holonyak had another connection with early light emitters.
He had been John Bardeen’s first graduate student, the same Bardeen that invented the transistor at Bell Labs in 1947 with Walter Brattain and William Shockley.
Shockley, along with Howard Briggs and James Haynes, applied for a patent on infrared LEDs in both silicon (1.1µm) and germanium (800nm) as early as 1951.
The silicon device only appears to have worked at liquid nitrogen temperatures, but the germanium LED worked cryogenically and at room temperature.
1951 is an early year for LEDs, but it not the first.

LED PARlights

Marconi’s assistant Henry Round ­reported light emission from carborundum (raw silicon carbide) “and other substances” in a 1907 letter to Electrical World when he was working on cat’s whisker detectors (diodes) for radio.
From SiC, he saw a yellowish light at low voltage, then yellow, light green, orange and blue at higher voltages on different points of different crystals. “In all cases tested, the glow appears to come from the negative pole, a bright blue-green spark ­appearing at the positive pole”, he wrote. Round noted a possible link between the voltage across the carborundum junction and the light emission. 
No other records of semiconductor light emission are known until the mid-1920s when self-educated Russian scientist Oleg Losov also noticed light emission from SiC, as well as zinc oxide radio detectors.
No one knows if Losov had heard of Rounds observation. Light from SiC detectors could have been common knowledge.
What is known is that Losov looked deep into the subject, publishing multiple scientific papers in Russia, England and Germany between 1924 and 1930 describing the spectrum of light emission in relation to the current-voltage characteristics of SiC cat’s whisker diodes.
Losov’s discoveries include establishing the v=eV/h formula that links diode voltage drop to emission frequency and, in 1927, he patented a ‘light relay’: probably the first reference to LED-based optical comms.

LED AR111lights

In a possible prelude to Brattain, Bardeen and Shockley’s transistor work, Losov was working on an amplifying three-terminal semiconductor device during the siege of Leningrad in 1941, in which his paper on the subject was lost when he later died of starvation.
Surprisingly, this is not the first know reference to transistor-like devices as Edgar Liliendfeld filed a Canadian patent in 1925 on a FET-like device using copper sulphide, including a radio receiver design in which to use it.
Back with cold light emission, the impressively named Zoltan Bay together with Gyorgy Szigeti pre-empted LED lighting in Hungry in 1939 by patented a lighting device based on SiC, with an option on boron carbide, that emitted white, yellowish white, or greenish white depending on impurities present.
The patent does not mention junctions, and light emission is said to be related to applied voltage, rather than at a fixed voltage that even Round postulated, so this may have only been non-junction electroluminescence.
Another early character to have touched LEDs is Kurt Lehovec, who is best known for inventing junction isolation for integrated circuits when he worked for Sprague, patenting it in 1959.
Less well known is that in 1952 he applied for a patent on SiC visible light LEDs.
He appears to have grown n-type SiC doped with arsenic, then locally introducing boron with an electron beam to make p-SiC for the junction.


In the patent he speaks of ‘activator’ impurities including silver, lead, manganese, bismuth, thallium, tin, copper, zinc, cerium, europium and samarium which are proposed to control the colour of light, noting blue, greenish-yellow and pale yellow emission.
Lehovec seems to have made a manganese activated SiC LED, measuring operation to over 200kHz, and proposes it be used to record the audio track down the edge of movie film.
Also worth a mention are Rubin Braunstein and Egon Loebner, working at RCA, who in 1958 patented a green LED made from a lead antimonide dot alloyed to p-type Ge.
First infrared LEDs
There followed the blossoming of II-VI, III-V and IV-IV research out of which Holonyak’s first GaAsP red LED sprang.
John von Neumann had theoretically considered the essential elements of a semiconductor laser in 1953, and in 1961 it had been known for some years that GaAs p-n junctions could emit photons. Research groups in the US, UK, Russia and France were all attempting to turn semiconductor laser theory into practice.
In mid-1962 Robert Keyes and Theodor Quist at MIT, and a group led by Jacques Pankove at RCA, revealed high efficiency infra-red emissions from GaAs p-n junctions – ­infrared LEDs, and combining this with a GaAs photodiode transmitted TV signals optically from a mountain into the MIT laboratory.


That August, James Biard and Gary Pittman of Texas Instruments filed a patent on GaAs infrared LEDs. 
Following on from the MIT work, and still in 1962, Gunther Fenner under Robert Hall at GE used GaAs to make the first semiconductor diode laser.
A visible LED
This first laser kicked off a month of activity in which Robert Rediker at MIT, Holonyak at a different GE lab, and Marshall Nathan at IBM all made lasers.
All but Holonyak’s were infrared, using Zn diffusion into n-type GaAs, whereas Holonyak’s was his red-emitting GaAsP device – also credited with being the first alloy compound semiconductor device demonstrated.
Holonyak had been working on GaAsP on GaAs substrates, as well as GaAsP on GaAsP (with a different As/P ratio) substrates since 1960 for his tunnel diodes – possibly making the first hetero-junction semiconductor devices in the process.
He went on to join the University of Illinois where he became the supervisor of aspiring GaAsP LED ­researcher George Craford.
With his PhD from Illinois and inspiration from Holonyak, Craford moved to Monsanto in 1967 and with a team of researchers invented ­orange, yellow and green LEDs using GaAsP on GaAs substrates.
The key was nitrogen doping, the idea for which Craford credits a presentation by a Bell Labs researcher – Bell Labs was working with GaP LEDs, trying both ZnO and N as dopants.


Monsanto was probably the first firm to make affordable LEDs.
Craford moved on to HP in 1969, heading a group that pioneered AlGaAs for bright red LEDs and AlInGaP for bright orange and green.
LED as bulb replacement
By 1987 AlGaAs LEDs from HP were bright enough to replace light bulbs in vehicle brake lights and traffic lights, the first time LEDs displaced incandescent bulbs in a lighting application. AlInGaP followed in 1990, offering at least double the brightness of AlGaAs.
"High-brightness red AlGaAs LEDs were pioneered by Stanley Electric in Japan," Craford told Electronics Weekly. "At HP we developed our own version that were quite popular until replaced by AlInGaP."
HP also made a success of GaP materials, initially as bright green LEDs in 1993, then the next year as a transparent substrate that got a further 4x improvement in reddish-orange AlInGaP LEDs for car turn indicators.
Craford is now CTO at white LED maker Lumileds which, with Avago, is one of the two descendants of HP’s LED business.
As the 1980s became the 90s, the spectrum of LEDs was completed when blue LEDs, albeit dim blue LEDs, based in SiC finally went into production from the likes of Siemens, Sanyo and later Cree.
The story now moves across the Pacific where in 1988 researchers at Nichia, a chemical company little-know outside Japan, start studying GaN as an LED material.


Just like US-based Pankove had in 1971, many could see GaN’s emissive potential if only route to p-GaN could be established so a p-n junction could be made.
The best minds at the best labs in Japan were on the case when, at Nichia in 1991, researcher Masayuki Senoh succeeded where all others had failed and produced p-type GaN.
His technique was electron irradiation on a magnesium-doped substrate – not suitable for production, but enough to allow Nichia III-V growth expert Shuji Nakamura make the first p-n junction GaN LED – a homo-structured blue-violet device on a sapphire substrate.
"Akasaki was a key link in the GaN work between the early RCA work and Nichia," said Lumiled's George Craford. "Over a decade of work he developed MOCVD growth on sapphire, and made key breakthroughs such as buffer layer growth and demonstration of p-type GaN, amongst others. that Nichia later built upon and improved."
White LEDs
By the end of September 1991, Nichia researcher Naruhito Iwasa discovered a production compatible way to make p-GaN – annealing Mg-doped GaN above 600°C. With the added development of Zn+Si doping by 1993 the firm was shipping blue GaN LEDs that were 100x brighter than Cree’s SiC types.


Iwasa also found a way to get enough indium into InGaN to pull the wavelength down to blue-green for traffic lights, and by added quantum wells the firm finally had a pure green InGaN device by the end of 1995.
Like HP before it, Nichia was a hotbed of innovation which finally led it to opened the door to white LEDs, and ultimately lighting class LEDs.
Nichia researcher Yoshinori Shimizu – initially as part of a programme to make blue die emit green - identified YAG phosphors as materials tough enough to survive in an LED. Yasunobu Noguchi then developed a gadolinium YAG phosphor that could convert blue light to ­yellow, and Kensho Sakano combined Noguchi’s phosphor with a blue LED die to make a white LED.
This is necessarily a condensed history, skipping several companies that made contributions, particularly in getting LED inventions into production. Many of the people formerly credited as inventors are quick to share that credit with their colleagues.

WSRM---LEDlighting market Perspectives in the future!

WSRM---LEDlighting market Perspectives in the future!


The Global lighting market is on a clear transition path from traditional lighting technologies
to LED. However, world events over the past year have given clearer contours to the light- ing industry’s development, and some market parameters have shifted or accelerated.
On the one hand, the world’s ongoing financial turbulence and Europe’s debt crisis have inevitably had a negative impact on global and regional economic growth, both actual and projected. This has also adversely affected the lighting market.
On the other, regulation across the globe has become more stringent, fueling the penetration of more energy- efficient light sources, such as LEDs.


 For example, China has now passed legislation to ban incandescent lightbulbs. Governments have also reacted to the disaster in Fukushima(JAPAN)by debating(and in some cases deciding on) a nuclear phaseout. This is expected to boost the uptake of low-energy light sources that help to close the looming energy gap.
Another vital metric has altered. LED prices have eroded more aggressively, pulling forward the payback time of LED lighting. The inflection point for LED retrofit bulbs in the residential segment, for example, is now likely to be around 2015.  LED share in general lighting at 45 percent in 2016 and almost 70 percent in 2020 – 2 and 5 percentage points higher,respectively, than predicted in 2011.


Both the shifting macroeconomic context as well as the accelerating LED price erosion
have affected long-term forecasts of the size of the lighting market. According repport of  revenues of around EUR 100 billion for the global market in 2020 – a decline of over 5 percent versus last year’s forecast. The total market is expected to grow annually by 5 percent through to 2016, and by 3 percent thereafter until 2020.
A breakdown by sector shows that general lighting has been impacted the most. The forecast of market size for this segment in 2020 is around EUR 83 billion – some EUR 5 billion lower than last year’s projection.
The figures for automotive lighting (represent- ing around 20 percent of the total market) have changed only slightly. Adjustments to vehicle unit production and sales forecasts due to macroeconomic volatility have partially been offset by a modified methodology.
In addition, lower exposure to LED price erosion given the smaller LED share in this segment has further reduced the impact of market changes. The revenue outlook has remained stable, at around EUR 18 billion by 2020. Backlighting, by contrast, is antici- pated to shrink faster than previously estimated. Lower sales forecasts for LCD TVs and monitors, accelerated penetration of OLED (organic light-emitting diode) products, as well as higher LED price erosion are key contributors to a swift decline in market size, falling to EUR 1.0 - 1.5 billion by 2016.

LED DOWNlights

As last year, general lighting was divided into seven applications: residential, office,shop, hospitality, industrial, outdoor, and architectural lighting. The faster LED price erosion has raised forecasts for LED penetration in many of the segments – office, shop, and hospitality, for example, while decreasing the size of the lighting market overall by value. Forecasts for LED uptake in the residential segment remain high, at almost 50 percent in 2016 and over 70 percent in 2020. Architectural lighting remains the early adopter, and its LED market share is expected to reach close to 90 percent by 2020.
In terms of the regional split, Asia is expected to account for approximately 45 percent of the global general lighting market by 2020. Asia currently leads the market transi- tion to LED in general lighting, driven especially by swift penetration in Japan and
China. A new analysis this year – market segment by product grade for global general light- ing – reveals that the fastest growth is in the commodity segment, forecasting an increase of EUR 10 billion by 2020. Again, it is mainly Asia driving growth in this market segment.

LED TUBElights

Meanwhile, disruption of the industry structure is becoming more apparent. Value in the LED chip and package market is set to shift from backlighting to general lighting, and players are beginning to expand downstream along the value chain. The evolving LED market is impacting industry dynamics along the entire general lighting value chain, with effects on light engine standardization, the fixtures market, replacement versus new instal- lation, and channel mix.
New business opportunities are also emerging as the industry landscape is redrawn.
The lighting control system market is already mushrooming, with a growth rate antici- pated at almost 20 percent p.a. through to 2020. While office is currently the largest segment in this area, expansion is expected in residential and outdoor. Service-related businesses in the fields of maintenance, technical solutions, and financial servicesrepresent merely the beginning of what promises to be a new era of business models in the lighting arena.The transition of the global lighting market towards LED is triggering and accelerating ever more pronounced discontinuity in industry structures. Players will be well advised to analyze the coming repercussions in their segment of the value chain, and position themselves for change.

Overall,LEDlights is a unreversed trend to replace all of the traditional lights in the world!
