LED has been most people know, it was the most optimistic, that is a new generation of lighting source in twenty-first Century. According to the current forecast to around 2010, may be close to 50lm/W light efficiency, so the hype was seething. However, after all, a single power of about 0.1W, so the luminous flux is very limited. At present, it is necessary to integrate a lot of LED in order to make a new light source to replace the incandescent or compact fluorescent lamps, lamps, wall lamps and other lamps, these examples have been a lot of. But the high price, it is difficult to promote, to achieve a reasonable price of the era seems to have to wait for some time.

The United States LD+A 7 this year published a message: the advantages of using the LED control voltage is very low and simple control method, it will be installed in the indoor ceiling or made large lighting, through the computer output signal directly switching triode to control it. Due to the use of the computer, the number of LED can also be more convenient to control, to get a variable color when the variable color colorful lighting effects, and has been successful cases. For example, in the United States, "Rainforest Cafe" made a color changing color ceiling, in the Hollyword casino made a color spot rotten large art chandelier.
