Influenced by the world Energy Policy, to increase the demand for LED lighting, LED lighting manufacturers are rushing to develop lighting products, the luminous efficiency of a single high-power LED light has been increasing. Pei Xin, from LED lighting applications, said that LED luminous efficiency is developing at the speed of increasing by 20 lm / w each year. It is expected that high power LED commercial light-emitting efficiency may increase to 100 lm / w in March or April in 2008.
LED, with the characteristics of power-saving, long life and low heat, is considered as the new light source of the next generation. The light-emitting efficiency gains speed rapidly, from 1996 the commercialization of 5 lm / w began to advance rapidly, Nichia, the market leader of LED, enhance the luminous efficiency of 100 lm / w in 2006, which brings LED luminous efficiency in a new milestone, the other international companies such as Cree, Philips (Lumleds), Ou Silang (Osram), Seoul Semiconductor also struggle to catch up, the luminous efficiency competition has increased from 80 l / w upgrade all the way to 100 lm / W.
When the luminous efficiency of the LED chip breakthrough the threshold of 100lm / w, it means a big step forward towards the luminous efficiency of lighting that applications required. LED industry estimates that the compound annual growth rate of the high power LED lighting applications will reach up to 75.2% from 2006 to 2010 and the high-power market will be 3.8 billion U.S. dollars (25.46 billion RMB) in 2008.
Taiwan LED industry commonly lagged behind the development of Japanese, American and European manufacturers. According to industry, if combine Cree's LED chips with Nichia’s phosphor, the light-emitting efficiency is expected to increase to 130 lm / w, but the cost is too high and it is difficult to achieve commercialization stage. Hence, the luminous efficiency of LED lighting products is mainly 70 ~ 80 lm / w at present.
But Taiwan's industry pointed out that in terms of the development of LED lamps, before the lighting standards are formulated by the country, the products with luminous efficiency about 60 ~ 75 lm / w is sufficient to replace the existing high pressure sodium lamp, what’s important is how to solve the LED heat problem and avoid light decay.
The lighting market is still in start-up stage, many Taiwan LED industry think that although business opportunity is formidable (wholesale LED lights), it is still in the "with sound, no shadow" stage. But Pei Xin Semiconductor point out that it plans to introduce the commercial product of 100lm / w in 2008. Because of the LED luminous efficiency will increase to 150 lm / w in 2010, with the condition of upgrade in the light-emitting efficiency, the cost of LED lamp is expected to reduce to twice less than high pressure sodium lamps (wholesale LED christmas lights). Then it will be entering the outbreak of growth of LED lighting applications.from: cheap LED lights
