First of all, in the local online public resources trading center to declare. LED lights factory it is a solid cold light source, green pollution-free, less power consumption, high photosynthetic efficiency, long life, therefore, LED lights will be a road lighting energy-saving renovation of choice. 

The LED street lamp which is a kind based on semiconductor PN junction formation with weak electricity can glow efficient solid-state light source, in certain positive bias voltage and the electrical flow injection, injection of holes and injection P N the electronic after spread to have source area by the radiative recombination and emit photons, convert electrical energy directly into light energy. After completion of online information will be considered the original company.
