Lightning induction problems used in LED street lights

my country's road lamps and lanterns basically adopt the mode of HID light source plus trigger and inductive ballast, although this mode has the problems of low energy efficiency and stroboscopic. An important aspect that threatens the plasticity of LED street lamps with electronic drive circuits when used in outdoor lighting places is the lightning induction problem.　To solve this problem, it is necessary to connect a fast-response varistor at the input end of the outdoor LED street lamp driving circuit to ensure the leakage of differential mode interference. Since the induced interference of lightning is repeated many times, when the interference voltage is high, the instantaneous conduction and discharge current of the varistor may be large. Therefore, the varistor used should not only have a fast response capability, but also have an instantaneous conductivity. The discharge capacity of dozens of amperes is not damaged. When designing LED street lights, it is necessary to emphasize the remuneration, to provide people not only with elegant and comfortable lighting environment, but also to provide a safe light environment. In the design, the position of the lighting LED street lamp can be set reasonably and the light can be selected. The lighting design effect can be achieved by adding light-shielding plates and grilles, and avoiding light pollution and safety hazards of LED street lamps.
