Install solar LED street lamp is slowly took over in the night street lighting, solar LED street lamp is not to use electricity from the grid and produce each own endurance, allow zero electricity bills for the life of the system, absorb the light energy to solar panels during the day, and then converted into electricity to light at night. Rational allocation of solar LED street light, solar system, means they produce enough electricity during the day, to offset the lights in the night at the use of electricity. Make solar LED street lamp can be normal use is in designing the lights, take into account the solar energy conversion rate, the required illuminance and power of lamps and lanterns. If it's a traditional street lamps don't without considering the distance between street lights, light level and the power consumption of these requirements, using only a few light source, rely on the use of power supply, make traditional lighting effect greatly discount, service life and reduce a lot. With the progress of our solar technology, the installation of solar LED street light, the optical system can be used to provide specific lighting on the ground, let the light shine in all directions, provide to use the power of a higher power.
