Solar street lamps to parse, from the perspective of a simple is that it converts light into electricity directly use the street lamp, do not need to use electricity costs, solar street light price is not expensive believe everyone will like to use. Although we know the solar street light is in using light energy into electrical energy use, but we don't know how it works, and what is the advantages of it to run. Solar street light energy conversion device is a basic solar panels, it is a kind of by Yu Guangsheng v effect and will transfer sunlight into electricity system, is when the sun light to the photodiode, photoelectric diode will convert the sun's radiation to electricity and generate an electric current, after accumulation, you could have passed the battery until dusk can light in implementation. Because of the existence of renewable solar energy resources, solar street light can be said to be an investment and long-term use, long service life, compared with the dynamic power and nuclear power, solar street lights will not cause environmental pollution, and permanent, clean, and the advantages of flexibility, is also a kind of promising new solar lights.
