The development of LED street lights is a progress of the times, allowing urban roads to accelerate into the ranks of energy saving and environmental protection. The use of LED street lights can reach 80% perfection, and there are still some problems that need to be solved at present. The problems with the power supply of LED street lights have always been the biggest headache for manufacturers. It can be said that the LED street light power system is very unstable. LED street lights are installed outdoors, the working environment of the power supply is relatively harsh, some components of the power supply are easily damaged, and the use of the power supply is unstable during use, which will affect the lighting effect of the LED street light, and if it is serious, it will cause the LED street light The service life is reduced. The wattage requirement of the LED street light source cannot meet the market demand. Unlike high-pressure sodium lamps and metal halide lamps, the wattage of the light source can reach 300w or 400w, and the brightness of the lighting can meet the needs of the market. I believe that the LED street lamp solves these two problems, its development will be further, the scope of application will also be expanded, and better market promotion.
