It has the advantages of high efficiency, long life, easy breakage, high switching speed, high reliability and other traditional light sources. The luminous efficiency of white LED has obviously been improved in recent years, and at the same time, the purchase price of each lumen is also due to the impact of competition among the manufacturers in the market. Although more and more people use LED lighting for office, furniture, decoration, signs and even street lights use, but in technology, led in photoelectric conversion efficiency (effective illuminance on the ratio of electricity consumption) is still lower than the new fluorescent lamp, is the country's future development of civilian.
