LED as a new light source, is increasingly being integrated into people's daily lives, it is inseparable from the development of the demand for lighting. Compared to traditional light sources (such as fluorescent and incandescent), LED at close to the theoretical conversion efficiency than conventional light source efficiency 5-20 times higher. Even at this stage of mass production light effects, its level is between 2-15 times, combined with the advantages of its directivity, this gap will be even greater. Due to changes in light principle, the life will be much higher than traditional light sources.
