We all know that outdoor solar-led street lights are powered by solar energy so even if there is no electricity at night that will not be able to affect it. Now, outdoor solar-led street lights have been installed in rural and urban areas. We all know that outdoor solar led street light system is made up of a lithium battery pack, a solar panel, a solar charge controller, a led source, etc. its working principle is that solar energy is received by a solar panel and then stored on a lithium battery by the solar charge controller. in the evening, the solar charge controller will automatically turn on the outdoor solar led street lights. Do you know why solar street lights must use LED sources?
First: the combination of LED light sources can achieve a variety of dynamic effects and various images.
Second: LED resource is easy to install.
Thirdly: because the LED light source is a low consumption product, its energy consumption is one-ninth of the incandescent lamp. It needs to consume little energy but has a long life.
Fourthly: The S-W(Staebler Wronski) Effect of high-voltage sodium light is more serious than the led source, so the service light of high-voltage sodium light is shortening than LED light.
Fifth: High luminous efficiency. The LED source is unidirectional irradiation and the light efficiency is better than an ordinary incandescent bulb. The diffuse phenomenon can not occur.
In addition, a led source has a lot of advantages, such as environmental protection, no radiation, small volume, lightweight, etc. So LED source has become the necessary light source of outdoor solar led street lights.
