White light-emitting diode (LED) when it can achieve 100lm / W luminous efficiency and power consumption than fluorescent lamps in it? Matter of concern since a long time has come to solve the moment. For Nichia Chemical Industries in June 2006 will soon start sample shipments of luminous efficiency of 100lm / W white LED. It is reported that in December will be mass production.
100lm / W, which is light with high efficiency fluorescent species in comparable indicators. Although there had been higher than in Society 100lm / W white LED of the report, but 100lm / W products available is the first time.
Ability to achieve 100lm / W is not only a Nichia Chemical Industries. Estimated that in 2006 as the start to 2007, 100lm / W products are listed one after another. For instance, Citizen Electronics (Citizen Electronics) product planning, 06 years to produce 90lm / W products, 07 100lm / W products will appear. White LED technology as the highly competitive industry, and other LED manufacturers will surely follow up the launch of 100lm / W products. One step ahead than other companies launch products Nichia Chemical Industries announced that after 07 years to complete 150lm / W product development, therefore, high efficiency, competition will not cease for some time.
A year ago, said a white LED with high luminous efficiency of the species, there are only 60lm / W or so. But in the actual brightness, and fluorescent lamps have been similar. This is because, with the full range of fluorescent light emission is different only to the front of the white LED emission. Now, thanks to a white LED to achieve a 100lm / W, it should be said in the luminous efficiency of more than a fluorescent lamp.
Luminous efficiency white LED With the increase in use is also increasing. From for the "display" white extension for "light" objects in the set venues, from public space to become more and more personal space. Such as lighting, the Matsushita Electric designs using LED as the apartment (Designers Mansion) lighting products have been well received. Equipment in the car, you can backlight the instrument panel and interior lighting on to see examples of many applications. LED headlamp with white listed vehicle will be in 2007, Toyota held in April 2006 New York Auto Show (New York International Auto Show) on display, and plans listed in spring 2007 Lexus brand premium sedan "LS600hL "on the use of a white LED as a headlight beam.
In 2005, people's general view is, the market began to 100lm / W white LED products are the earliest in 2007 ~ 2008. The reality is that more than 1 year earlier, it was considered one of the reasons for its technology development is not only a hot competition, but also a sharp decline in prices should cause this area. Small Power (0.1W-class) white LED's price terms in 2003 Q1 is about 65 yen. To about 54 yen over the same period in 2004, in 2005 about 40 yen in 2006 and then fell to less than 30 yen. 3 years, prices dropped to below half.
South Korean and Taiwanese manufacturers enter the market vendors have brought prices fell sharply in the future to predict the varieties of Chinese manufacturers to increase further in the low-cost white LED may be on the road at full speed. On the old white LED makers, can only improve luminous efficiency, achieve high value-added products, to curb the price down, and get on-board equipment, lighting equipment and new market development tools. These factors also high luminous efficiency white LED technology has played a large turnout.
Both the white LED, the average unit price continued to decline, or part of the introduction of powerful companies luminous efficiency 100lm / W for high-end products, for as the user's equipment manufacturers are welcome to do. Because both cases, the unit price per 1lm beam (lm / yen) are on the decline. To reduce the white LED lighting uses the existing fluorescent and incandescent lamps above the more than 10 times higher than the previous uses tungsten lamp and HID light nearly 2 times the price, it is necessary to further reduce prices and improve the luminous efficiency.
However, some people feel, to use and vehicle use in the lighting so widely used in white LED, only the prices are not enough. For example, there must be inhibited to drive a white LED power supply circuit measures the power loss. Backlight for cell phones and other low-power white LED power supply circuit in the power conversion efficiency of 90%, while for the intended use of the high-power white light LED current can only reach 80%. In fluorescent lamps, the power supply circuit in the power conversion efficiency of more than 90%. That is, the loss of power supply circuits are still 2-fold difference. Using high-power white LED, need to invest a large current, also need a high heat printed circuit boards. Install the device easy to operate when the white LED is also critical.
