Outdoor LED street lights are usually powered by a power supply that converts alternating current to direct current.
The power supply voltage required by LED semiconductor is relatively small. This is different from the instantaneous high voltage withstanding ability that the traditional high voltage street lamp owns. The led street lights themselves don’t have the ability to withstand the peak current and overvoltage from outside.so it is necessary to hold the surge protection device for led street lights.
