LED hot for what?

The Institute of semiconductors have the well-known semiconductor lighting R & D center, LED hot fill latent heat, make this country want to build LED industrial base city to visit and study.

The LED not only in Shenzhen, Yangzhou hot Chinese, Jiuzhou and other small city, including Micron, TSMC and other global semiconductor bosses are also in the recent rush to announce to enter the LED market, and the global leader in EMS Taiwan's Hon Hai Group also announced a foot LED upstream of sapphire crystal industry.

How much the LED market? The topology Research Institute estimates that in 2010 the global LED output value of $8 billion, the annual compound growth rate of 13% to 20% to 2012, the global output value will reach $10 billion 800 million. At present, the main application market is the display, backlight, automotive and other fields. According to the foreign authority predicts that future LED market the largest application field is the general lighting market, if you can completely replace the fluorescent lamp, believe that there may be more than $300 billion of the potential market size. This figure will exceed the global IC sales of $250 billion in 2008.

Faced with such a large future market, who can resist the temptation and not to be tempted? But when it can reach $300 billion, it seems that no one can answer this question.

If Moore's law can be extended to the same category of LED in the field of semiconductors, then the improvement of efficiency and power, as well as the reduction of costs should be the goal of LED Moore's law. When the price of LED can compete with fluorescent lamps, incandescent lamps, the market will naturally favor this energy-efficient lighting star".

At present, the Chinese Academy of Sciences Institute of independent development of the second generation of high-power 80lm/w LED has been successfully applied in the main trunk of the Institute, in terms of energy efficiency and service life has withstood the test.

The Google type "LED price", a Taiwan LED free agents, online 3W-120-140LM high power LED lamp price is 16.5 yuan, 140-160LM high power LED lamp price is 19 yuan. Although the LED lamp compared with incandescent lamp can save a lot of energy, life expectancy is 10 times longer than incandescent lamp, 20~30 times longer than fluorescent lamp, but compared with one to two yuan an incandescent lamp, the initial investment seems a bit too high.

I believe many big names and semiconductor scientists to pursue the way in the way the LED Moore's law, but the price may not achieve rapid decrease in a short duration of time. After China became the world's solar energy manufacturing base, because of LED, China and the world have a chance to start at the same time, which may be lucky for China's semiconductor.
