The LED (Light Emitting Diode), referred to as LED, are solid-state semiconductor devices that convert electrical energy into visible light. They convert electricity directly into light without carbon dioxide emissions and light radiation contamination.

Known as the fourth-generation lighting source or green light, the LED has features of highly efficacy, energy-saving, environmental protection, long life, small size and easy maintenance. 

Its lifespan can reach 50000~100000 hours, 10 times longer than that of traditional light source. 

Power conversion is close to 100%, and the same lighting effects can save over 80% energy than traditional lighting sources.
