100lm/W white LED come out to embrace a wider range of applications

Long white light-emitting diode (LED) to the topic of people is when can achieve the luminous efficiency of 100lm/W? In terms of power consumption than fluorescent lamp? This concern has finally come to the solution time, but in fact, the luminous efficiency of 100lm/W on LED manufacturers is an important milepost, originally estimated in the 2008 to 2010 years are likely to reach this goal.

However, according to Japanese media reports, Nichia chemical industries (NICHIA) will begin to provide 100lm/W luminous efficiency of white LED samples in mid 2006, and is expected to start mass production before the end of the year.

"Luminous efficiency up to 100lm/W"! This makes LED industry how excited, white LED luminous efficiency can compete with the traditional light emitting component, in the past LED studies published by circles, had made a research report 100lm/W white LED, but can achieve true 100lm/W LED products, is the first time to see in the city on the surface.

Time back to 1 years ago, said high luminous efficiency white LED products, was only about 60lm/W, although the actual brightness, have be roughly the same and fluorescent lamps, but because the LED with a fluorescent lamp with a full range of emission light source, white LED only to the front of the launch. Today, the white LED to further achieve the luminous efficiency of 100lm/W, in fact, the brightness should be beyond the fluorescent lamp.

All the sales in the market of white LED chip products although many, but the power consumption of these products is large, and the luminous efficiency is low, a method for lifting module or light emitting device efficiency is the simultaneous use of multiple chips, but in this case, each a white light LED chip can output larger LM, power required to maintain high efficiency but less.

Therefore, Nichia chemical industry for the white LED chip which shows the prototype chandelier in the 45W input up to 4536lm/W, but the spotlight is used 80 chip, in 4.5W input up to 480lm/W.

^ luminous efficiency of 100lm/W on LED manufacturers is an important milepost.

In addition to Nichia, has the ability to 100lm/W manufacturers, including CITIZEN electronics in Japan (Citizen Electronics), its internal product planning, in 2006 will develop 90lm/W white LED lighting display products, is expected to come out in 2007 will be 100lm/W.

Because the technology of white LED industry competition is intense, other LED manufacturers must also will follow up the launch of 100lm/W products, but the white LED manufacturers development blueprint, Nichia chemical industries accelerated the evolution of the product schedule, and the opportunity in 2006 and set a new goal to achieve 150lm/W white LED; therefore, it is foreseeable "high efficiency white LED competition in a short period of time will not stop. "

In the past, the general LED can only serve as the indicator light, display light, but with today's technology development, production yield, enhance the brightness enhancement, high brightness LED step by step into the lighting market with great potential.

In other words, from the pure white LED used in the "display" extended to "lighting", set in place, from the most simple to the development of public space, close to the personal, for example, in the lighting, the use of various types of Matsushita color LED as Design Apartments (Designers Mansion) lighting equipment Japan won the praise of the market.

Also in the vehicle equipment, but also can be used as a dashboard backlight source, and indoor lighting to see many applications. In addition, TOYOTA in early 2006 New York Auto Show (New York International Auto Show), on display in a white light LED as the front lamp of automobile, in addition, high order car Lexus also plans in early 2007 to develop white LED as application of near light headlamp of automobile.

In 2006, LED industry are generally of the view that the market began to appear white LED products 100lm/W also need to wait, but the actual situation is ahead of the 2 to 3 years or so, some people think that the reason is not only the competition among manufacturers as a result, the price is the main reason to decline sharply.

Also, to enter the market in South Korea manufacturers and manufacturers in Taiwan brought a sharp decline in prices, the future can be predicted, manufacturers of varieties will further increase, likely in the low-cost white LED at top speed on the road. Many of the white LED manufacturers, only by improving the luminous efficiency, achieve high value-added products, to suppress the price decline, but also for lighting equipment, vehicle equipment and expand new markets, and these factors are of high luminous efficiency of white LED plays an important effect.
