Led solar street lamps are basically by the solar panels or batteries, and the controller and of all the accessories of solar panels or batteries, are all on the controller, so in this case, what goes on when it will go out, when charging panels or storage battery charging and discharging are done through the controller, which means the controller can now be integrated, can be set arbitrary time according to the actual situation. When there is light in the daytime, the solar street light panels can convert light energy into electricity, and stored in existing storage battery, and in the evening battery can supply LED light source, and can be used for lighting, solar LED street lamp luminous power generation system is an independent, don't need to worry about the problem of power outage. Cold light power led solar street light itself is relatively small, the source of life is long, can reach 5000 hours, to minimize maintenance of the circuit, and can replace the light source anytime and anywhere.
