Solar street light is belong to the intelligent manipulation of the outdoor lighting, its constant current drive, power can complete intelligent control based on the requirements. Combined with the traditional power supply converter, MCU to complete the LED light source integration control light-control + control + active power control, and even can automatically adjust the light. Which also reflects this solar LED street light is a combination of solar energy and LED light source is used, their combination is the outdoor lamp energy saving and environmental protection, make the service life of the LED solar street lamps and environmental security can be very good guarantee, so they bring more evident advantage is obvious, can go to reflect from different aspects. Solar street lamps low voltage operation and not black chimney caused by high pressure adsorption dust, safe and reliable. Low operating temperature, cold light, LED light source to heat dissipation, the operation temperature is lower than 60 degrees, will not lead to aging yellow lampshade. Can be dramatically reduced glare and light pollution, but also greatly improve the effective utilization of solar street lights.
