LED Lighting Market in Japan in 2010 Surged by 95%

Abstract:

The Japanese institutions Yano Economic Research Institute published a report in December 2010 that benefit from the measures taken by the Japanese government to increase public utilities, the overall lighting market in Japan this year (2010) was stimulated. It’s estimated the growth rate will be 2.7% which leads to a market of 7,420 billion yen in total. The growth rate in 2009 was 5.4% declined, the situation will be reversed in 2010.

The Japanese institutions Yano Economic Research Institute published a report in December 2010 that benefit from the measures taken by the Japanese government to increase public utilities, the overall lighting market in Japan this year (2010) was stimulated. It’s estimated the growth rate will be 2.7% which leads to a market of 7,420 billion yen in total. The growth rate in 2009 was 5.4% declined, the situation will be reversed in 2010. Since Japan has revised the energy saving regulations, the demand of LED lighting products has been driven dramatically. It is expected that LED lighting market in Japan will be surged by 95.2% (2010 to 2009).

Yano said, globe-type LED light bulbs, as the major LED-based lighting product, are mainly used to replace traditional incandescent light bulbs. But entering 2010, LED lighting products which are claimed to replace fluoresent lamps are starting to appear on the market (fluorescents dominates approximately 70% of Japan’s current market of overall lighting). Moreover, some large local enterprises start to undertake LED light tube market which was undertaken mainly by oversea enterprises in the past. Therefore, the LED lighting market in Japan is forecasted to be further expanded in the future.

Comparison of Several Typical Stuctures of LED T8 Tubes / T10 Tubes (Diagrams)

Probably, we’ve seen a lot of LED T8 Tubes in the market now or some of us may have carried out some projects that involved LED Tubes practically. So how about we take some time to look into some typical LED tubes by using some structure diagrams of LED tubes? I’d doubt that you have seen all of them before…

Take figure 01 and figure 03 for example, the typical structure of LED Tubes is: PC cover, LEDs, PCB, Heat sink and Driver(drivers do not show in these pictures).

PC cover: can be water-clear (transparent) and diffuse (milky).

LEDs: common LED type is SMD3528, some would be SMD5050, SMD3012 or SMD3014 etc.

Heat sink: typically aluminum but some may adopt PC (plastic) instead. Aluminum is good at rigidity and heat sinking while it significantly increases the weight of the tube.

Cree demonstrates 60W-equivalent LED retrofit lamp

Cree demonstrates 60W-equivalent LED retrofit lamp

LED-based A-lamp achieves Energy Star requirements for 60W replacement lamps, but Cree hasn't formalized plans to bring a product to market.

Cree has developed an LED-based retrofit A-lamp that it claims is the first design that can meet Energy Star requirements for 60W-equivalent products. The company is having the performance of the design validated by a third-party testing lab, but has not decided how or when the technology will come to market.

The demonstration lamp outputs more than 800 lm with a color temperature of 2700K, CRI of 90 or better, and power consumption less than 10W. Cree expects third-party testing to validate lumen maintenance to L70 of 25,000 hours. Energy Star specifies 25,000 hours, and Vice President of Corporate Marketing Greg Merritt said, "We want to at least achieve that."

Cree has not provided details on the light-engine design, but Merritt stated that the performance is enabled by Cree's XLamp LEDs, TrueWhite Technology and patented remote-phosphor technology. TrueWhite Technology mixes light from yellow and red LEDS to offer warm white light.

Dual-dome remote phosphor

Cree hasn't previously announced remote phosphor technology. Merritt describes the retrofit bulb as a dual-dome design with the remote phosphor deployed in the inner dome.

The design uses a passive cooling scheme enabled in part by the increasing efficiency of LEDs according to Merritt. In the nearby photo you can see the cooling fins. Merritt said, "It looks more like a traditional bulb" when asked about more radical designs such as Philips' products that leveraged air channels between portions of the lens. Merritt asserts that consumers have voiced a strong preference for replacement lamps that look like traditional bulbs.

Merritt made the point repeatedly that the development of the retrofit lamp was not simply an engineering exercise. He also acknowledged that Cree hasn't decided how to proceed with the product. Merritt said, "We haven't decided if, how, or when we will bring it to market."

Merritt did hint at a strategy saying, "We have a strong track record of making our innovations available to our customers." When asked if that meant customers of Cree LED components, Merritt added, "All of our customers, customers who want to make similar products." That comment implies that the demonstration is essentially a reference design.

Cree CEO Chuck Swoboda made similar comments about Cree's lighting business in the keynote speech he delivered at a recent LED developers' conference presented by Cree and Arrow (see links at the right for full details). Swoboda had indicated that Cree's system business was largely dedicated to system development that can help customers solve problems thereby ramping component sales.

At the launch of the A-Lamp demonstration, Swoboda said, "We are committed to leading the market and showing the industry what's possible with recent innovations in our LED products and technology. We are excited to show the world what it should expect in an LED light bulb and enable our customers' products with these innovations."

Low cost and high performance

Both Swoboda and Merritt emphasized that the A-Lamp design was designed to be cost-effective and to yield quality light. "In the race to commercialize low-cost, energy-efficient LED bulbs, the industry has forgotten that LED lighting is supposed to look as good as the technology it is replacing," said Swoboda. "This is the first no compromise replacement for a 60 watt incandescent bulb."

When asked about the goals of the project, Merritt said, "We wanted to demonstrate that you could do this with a product that was designed for mass production at an attractive market price." When reminded that the product price was still an unknown, Merritt added, "Obviously you have to take me at my word for this because I'm not telling you how much it costs."

Given the specifications of the retrofit lamp, we wondered if the design might be entered in the US . The DOE has temporarily suspended the PAR 38 portion of the competition while the Philips lamp remains the only entry in the A-Lamp competition. According to Merritt, however, the Cree design was optimized for cost. It doesn't produce the 900 lm required for the L-Prize.

The Cree lamp is designed to meet all of the elements of Energy Star for retrofit lamps. That includes the requirement for uniform light distribution below the equator of the bulb according to Merritt. Merritt asserted that no 60W-equivalent SSL product has complied with Energy Star requirements to date.

Cree chose the anniversary of Edison's patent issue date for the A-Lamp as the date to launch the retrofit demonstration. It was 131 years ago that the patent office recognized what became known as the Edison socket.

Taiwan LED Industry May Keep on Steady Growth in 2011

Taiwan Photonics Industry and Technology Development Association (PIDA) has recently predicted that the local LED industry will grow at a moderate pace in 2011.

According to PIDA , the output value of the global LED industry grew an increase of 68 percent from US$9 billion in 2009 to US$15.1 billion in 2010, and the number will further increase by 38 percent to US$20.8 billion in 2011.

Lu Shao-hsu, a PIDA analyst ,pointed out that Taiwan's output value of LED packaging and modules, which rose nearly 60 percent in 2010, is expected to increase only 24 percent in 2011 due to a higher base period comparison.

Deaphne Kuo, another PIDA analyst, also estimated that the global output value of large backlights, including applications for televisions and notebooks may approach US$7.3 billion in 2012 from an estimated US$2.98 billion in 2010.

Furthermore, based on technological improvements and the support of governments, LED lighting will become another factor driving the entire LED industry around the world, Kuo added.

City of Foley Considers Retrofitting LED Lights

It's reported that City of Foley is thinking about updating some new light throughout the city by experimenting with Led technology.

On Monday, Bravo Zulu, a technology company specializing in communications and monitoring technology have given a presentation focused on the benefits led light technology could have for the city, and ways the technology could be implemented to the city council.

According to Bravo Zulu , one of the main benefits of its LED technology is an included sensor system, which detects motion to turn the lights on when cars or people are nearby and dims the lights, using less power when no one is nearby.
So far, no decision has been made regarding the placement of LED lights in Foley, but the council is considering the possibility.

LED Light Underware, Would You Put That ON？

If I asked you, what can led lights be used for? I’m sure you’ll know the “standard answer”, which would be “led lights can be used for lighting”. Yes, I can not say that you are wrong, but I’m afraid with this answer, you could probably get an B (maybe B+, if you are lucky enough), but you would not get an A from me. Wondering why?

I always believe that, imagination is the greatest gift for mankind. Great imagination creates great things.

In this article, let our brilliant designers lead you into a dream world. These talented designers would let you know that lights are not only for decoration of buildings but are also capable of decorating human bodies, lights are not only lights, they can be clothes too. The following are some LED light clothes.

China May Come out the Restrictions to Phase out Incandescent Light Bulbs

After the EU, the US, Australia and others have imposed restrictions to phase out incandescent light bulbs, it's reported that China is in the process of making the road map for banning the use of these bulbs. The restriction is expected to be unveiled in March.

According to Wang Jinsui, director general of China Illuminating Engineering Society, said in China Business News," The National Development and Reform Commission has been drafting the map."

Wang said the initial plan is to stop producing 100-watt incandescent bulbs after 2015 and ban them completely from 2018. China has provided subsidies for using energy-saving light bulbs since 2008, prompting many incandescent bulb producers to cut their output.

Diagrams of Typical LED Spotlights: GU10

Continuing with our last post” Diagrams of Typical LED Light Bulbs: E26,E27” regarding globe E27 LED light bulbs, in this post, we will talk about GU10 LED spotlights.

 GU10 LED Spotlights

GU10 spotlights have been commonly used in spotlighting applications. Traditional GU10 spotlights are halogen lamps. Typically, under current light efficiency of LEDs, 3W LEDs is equivalent to 20W halogen lamps, and 5W or 6W LEDs is equivalent to 40W halogen lamps in terms of lux. Here the picture shows a 4*1W GU10 LED spotlights. See Fg. GU10 LED Spotlights.

From the appearance point of view,  GU10 LED spotlights and halogen spotlights look very similar. However, in fact, the difference between them is tremendous.

GU10 LED Spotlights Dimension

Light Source: light source is the essential difference between LED spotlights and halogen lamps, and that’s the reason why LED lights are much more efficient than halogen lamps. halogen lamps generate light by heating tungsten that covered by halogen gas, while for LEDs, simply describing, when current goes through LEDs, compounded particles in P-N junctions will then release photons (energy). LEDs generate less heat when emitting light, that’s the reason why LEDs are much more efficient than halogen lamps and incandescent bulbs.

Materials: materials are different, LED spotlights usually need aluminum heatsink for  heat dissipation while halogen spotlights do not – their lamp bodies are usually made of plastic.

Driver: furthermore, LED spotlights need drivers (or transformers) in order to be running in existing GU10 fittings, normally 110V or 240V high-voltage fittings.
The picture below illustrates a typical GU10 LED spotlight exploded view. The spotlight is decomposed into 7 components as can be seen from the diagram. The following are the corresponding annotations.

GU10 LED Spotlights Components

2. Screws
3. LEDs
4. MC PCB
5. Heatsink
6. Plug holder
7. Replacable plug: GU5.3,E26,E27,B22

I’ve been thinking to show people some interesting stuffs about LED lights, eg. LED light source, LED lighting fixtures, LED light components etc. In a series of articles (this one would be the first post, and there will be some other followed up), I will demonstrate some typical LED light bulbs by using some diagrams and annotations. Now just let’s start by one of the most commonly seen globe LED light bulbs: E27.  See Fg.: LED Light Bulbs E27

 

LED E27 Light Bulbs

From the appearance point of view,  globe LED light bulbs and traditional incandescent bulbs look very similar. However, in fact, the difference between them is tremendous.

Globe LED Light Bulbs E27

Light Source: light source is the essential difference between LED light bulbs and traditional incandescent bulbs, and that’s the reason why LED lights are much more efficient than incandescents. Rather than using tungsten wires, LED light bulbs adopt LEDs (Lighting-emitting Diode) as light source.

Materials: materials are different, LED Light bulbs usually adopt mist glass and aluminum, while incandecents usually adopt transparent glass and plastic. Reasons for that: LEDs emit very strong directional light (spot light), with transparent glass, the light would be too harsh to make people feel uncomfortable.  Therefore, it needs diffusion treatment – defused lens.

Driver: furthermore, LED light bulbs need drivers (or transformers) in order to be running in 110V or 240V high-voltage fittings, while the traditional incandescent light bulbs do not.

The picture below illustrates a typical globe LED light bulb exploded view. The light bulb is decomposed into 9 parts as can be seen from the diagram. The following are the corresponding annotations.

Do you know broken energy-saving lamps harms?

Nowadays, energy-saving lamps are increasingly replacing the traditional incandescent light bulbs, and become the most environmentally friendly lighting choice. To achieve their emission reduction targets, the EU is to phase out traditional incandescent that has been used for 120 years. People are mandatory  to replace their low-efficiency light bulbs with energy-saving lamps. In the UK, compact fluorescent (CFL) is the most common energy-saving lamps. Germany, however, warns the public based on a new study: the mercury released by broken energy saving lamps will be a risk to health, especially for infants and young children and pregnant women. While, LED lights, traditional incandescents, and halogen light bulbs will not cause such problems when broken, because they do not contain mercury.

German Federal Environment Agency claimed that, according to the new research, the mercury toxity of broken energy-saving lamps can be 20 times excess of interior safty guidelines’ standards. GFEA’s Board Secretary said that the presence of mercury in CFL energy-saving lamps is a major defect, therefore, new technologies are need to be adopted as soon as possible to prevent mercury pollution.  The advantage of 80% energy saving and safty of CFLs ought to be synchronous development. A council spokesman said that children and pregnant women should stay away from broken CFLs. In those places with children and pregnant women activities, protection lampshades are suggested to be installed to prevent mercury release by broken energy-saving lamps.

However, the British government insisted that the mercury risks of energy-saving lamps is over-concerned. Broken CFL bulb mercury hazard in fact is some occasional cases, not a big deal. UK Department for Environment, Food and Rural Affairs spokesman claimed that, the mercury containing in the CFL energy saving light bulbs is insufficient of harming the surrounding populations.

LED Lighting Facades

To illuminate the facades of buildings use special spotlights that are mounted on special brackets on the roof, walls, buildings and land.

In Russia and abroad produced many types of floodlights to illuminate the facades of buildings ranging from 35 to 2000 Watts. In the latest generation of projectors are commonly used halogen lamps and LEDs.

If you compare LED and halogen floodlights to illuminate building facades on the main characteristics, in many LEDs are absolute leaders. By quantity of light emitted by LEDs in the lead direction of the light radiation - halogen lamps lose up to 60% luminous flux. LEDs win for color purity and wide range of colors - up to 16 million colors (light filters halogen bulbs burn out quickly), ease of operation and energy savings (up to 6 times compared with halogen lamps). In addition, LEDs improve reliability and service life of lamps, as well as reduce maintenance costs (lifetime in continuous operation - 100 thousand hours).

With the help of a certain number of elements and various optical lenses LEDs allow you to create different projectors and lighting with the power required to illuminate the building. Modern control systems use light-emitting diode searchlights dynamic effects that are not available halogen lamps. The only drawback of LEDs - the high price and low unit capacity, ie for obtaining high luminous flux is required to use a large number of LEDs.

Over the past year or two, were first successful installation of LEDs in architectural lighting cities in Europe and the U.S. made the first attempts to use them in Moscow. In the city the use of LED lighting effectively, experts say that for private homes in the next few years this type of lighting would be dominant.

Cree's CEO suggests quicker LED move into general lighting (part 2)

Cree's CEO suggests quicker LED move into general lighting (part 2)
In part 2 of our review of the keynote at the recent Arrow LED event, Cree’s CEO notes a challenge in marketing and positioning that is hampering SSL uptake while describing how LED technology has progressed and is succeeding in general lighting.
Cree’s Chuck Swoboda delivered the keynote address at Arrow’s recent LED Lighting Design Seminar and focused the talk on LEDs in general-lighting applications. Part 1 of our article on the keynote described Cree’s general-lighting focus. In the letter part of Swoboda’s talk he focused on obstacles to success for solid-state-lighting (SSL) from a marketing and positioning perspective while chronicling how LED technology has progressed to the point that the technology will no longer gate success in general lighting. Indeed Cree is confident that LEDs are no longer an obstacle to cost-effective SSL. The industry does need to continue to drive the cost out of the system design. But Swoboda suggested that branding and marketing are as significant roadblocks to success as is the technology. Cree CEO Chuck Swoboda Swoboda pointed out a common mistake people in the SSL segment are making. He said “They either want it to be really expensive as a super-premium product or they want to make it as cheap as what it’s replacing. It’s neither. It’s a value sell.” To make his point, Swoboda discussed the widely-publicized partnership between Cree and Home Deport in selling the CR6 down light. Cree approached the move as an awareness campaign and Swoboda said, “Our only objective was to get them to put the demo in the store.” Cree hoped to test what would move the SSL market. And while he didn’t share details on product sales, Swoboda asserted that the product has done very well at a price ($50) that was broadly considered too high. He suggested that once people can see and touch SSL technology, they understand the value. “I think there is much more demand for LED lighting in the near term than anyone has thought about,” Swoboda said. “If the customer is comparing [LED lighting] to CFL it’s an even easier sell.” Earlier he had noted that the CFL had taught consumers that energy-efficient lighting was equivalent to a compromise in quality but that LEDs will change that perception. Efficiency and applications The Q&A session following the presentation was dominated by a discussion of LED efficiency, applications where LEDs are winning, and the challenges for luminaire makers. Swoboda affirmed that Cree is shipping the XLamp XM-L family of LEDs that he believes offers an industry-best 160 lm/W. He added that the company is doing better in the lab with prototypes operating in excess of 200 lm/W. Asked when Cree would ship such products, Swoboda would not commit but noted that the company has a track record of delivering production components 18 months to three years after lab demonstrations. The inevitable next questions centered on what would deliver the gains in brightness. One questioner suggested that bigger die would be the answer. While acknowledging that Cree has some LEDs based on larger die including current versions of the XM-L, Swoboda suggested that “die size is a short term solution.” In a separate presentation, Cree applications engineer Yuming Chen detailed the fact that larger die size creates the need for much larger secondary optics to prevent the light losses associated with the etendue effect. Instead, Swoboda believes that there will be advancements in chip design, phosphor technology and packing that deliver better efficiency. He stressed that by chip design he does not mean the actual epitaxy process. He believes that the industry is nearing peak efficiency in semiconductor devices. But he believes that there are other elements of chip design that can improve light extraction. Swoboda predicted that Cree will deliver LEDs with efficiency in the 220 to 230 lm/W range while noting that the company will be nearing the theoretical limit of converting energy into light at that point. The stress on efficiency is as much about thermal issues as it is brightness per se. As discussed in our prior article on the keynote, brighter LEDs simplify system design. Swoboda said, “When that thermal load comes down, everything gets easier.” Swoboda was also asked about a number of applications and when a “tipping point” might be reached. He believes that street lights tipped when LEDs hit 100 lm/W. The same level has allowed “a segment” of the retrofit bulb market to tip. But he noted that “converting a category of lighting is a really long process.” Swoboda was quick to highlight a potential market for SSL that has not been viewed favorably of late. He boldly predicted that LEDs would succeed sooner than expected in linear-fluorescent retrofit applications. Fast design cycles An audience member, clearly representing a luminaire maker, expressed frustration at the fact that the LED market is moving so quickly with new products and packages coming to market constantly. The questioner noted that before the luminaire maker can get a product to market and into volume manufacturing that the LED maker invariably had a new brighter product – perhaps in a new package – that was replacing the old one. Swoboda sympathized with the plight of the luminaire maker while opining that companies should go ahead and complete each design rather than stopping and changing light sources in the middle of a project. He used an LED street light manufacturer as an example of why. He noted that the company is on its fifth generation of its street light design, and that much more than the LED components were changed in each generation. He said, “They had to change [LED] platforms but they changed everything else each time too. Their product today is three to four times brighter, twice as efficient, and one fifth the cost as in gen one.” Swoboda made a bold statement that applies both to luminaire makers and to the LED component makers. To succeed he said, “You’ve got to want to obsolete your own products.” Swoboda said, “I don’t think there’s any doubt that the world is going to LED-based lighting technology.” And he succinctly summed up the reasoning behind Cree’s general-lighting focus saying, “If you get there early it works out a lot better than if you get there late.” About the author: Maury Wright is the Senior Technical Editor of LEDs Magazine.

China new energy efficiency standard will bring more non-compliant products to cut price

On December 1,  China new flat-panel TV energy efficiency standards was carried out, which contained three level standards: level one for most efficient products; level two for products that meet the lowest requirements for being labeled energy-efficiency products; and level three for products meeting the minimum requirements for being allowed on the market. It’s estimated that would stimulate more price-cut promotion on products that did not meet the standard.

When the new standards were first reported in the end of June, venders started cleaning their inventories in the next five months. So until recently, venders should have clean out their most inventories. Also, this meant that a higher threshold in terms of cost and technology, and small- to medium-size players would not have advantage from their low prices, with the first-tier vendors focusing on higher efficiency products.

At present, First-tier vendors focused on 46- and 47-inch models, while local vendors focused on 32-, 40- and 42-inch models. Local brands had seen prices of their 32-inch LED-backlit TVs drop below CNY2, 500, and prices of popular LED-backlit models had dropped by around 20%. Prices for 40- and 42-inch models had dropped below CNY5,000, and some models from China vendors had dropped to as low as CNY4,000.

SETI makes breakthrough in single chip germicidal UV LED

Tue, 09/21/2010 - 08:56 — jasminezhuang

Sensor Electronic Technology, Inc. (SETI) has shifted the power of UV LEDs operating in the germicidal wavelength range from 30 mW up to 100 mW.

At present, this level of single chip performance is not yet available in SETI's production LEDs, high power UV LED lamps are available under the UVCLEAN® trademark with germicidal powers up to 50 mW.

SETI demonstrated disinfection in an "on demand" drinking water system using 30mW LED lamps . As Remis Gaska, President and CEO of SETI noted, "High power UV LEDs are essential to achieve the level of disinfection required in point-of-use and point-of-entry water treatment systems. This ongoing development of large area high power UV LEDs will help to reduce the price per milliwatt and allow UV LEDs to enter cost sensitive disinfection markets."

It's reported that SETI will be presenting all the latest data on its high power single chip LEDs at the International Workshop on Nitrides (IWN) in Tampa, Florida, USA on September 19th – 24th.
