Today, LED street lamps have been developed in China for nearly ten years, involving power supply, power supply, heat dissipation technology, optical technology, etc., and each year is a new improvement. Some basic technical problems of LED street lamps have not been solved in China. For example, the lightning protection problem of LED street lamps is one of the problems to be solved. So why should we do a good job in lightning protection of LED street lights? How can we do it?

1、 The importance of lightning protection for LED street lamps

Lightning is an electrostatic discharge, which usually sends millions of volts of voltage from the cloud to the ground or another cloud. In the transmission link, lightning forms an electromagnetic field in the gas, forms thousands of volts (surge) to the power line, and forms an induced current hundreds of miles away. These indirect attacks usually occur on outdoor exposed wires, such as street lamps. Traffic signal lights, communication base stations and other equipment send out surges. The surge protection module directly faces the surge interference from the front power line of the power circuit. It transmits or absorbs surge energy to minimize the harm of surge to other working power circuits, such as AC/DC power supply units in LED lighting.

For LED street lamps, lightning induces surges on power lines. This current of electric energy forms a shock wave, or a shock wave, on the wire. The surge is transmitted according to this induction. The outside world is proliferating. This wave will form a tip on the sine wave of the 220 volt transmission line. When the tip enters the street lamp, it will destroy the power circuit of LED street lamp.

Therefore, lightning protection of LED street lamps will be beneficial to their service life, which is necessary at present.

2、 Specific lightning protection measures for LED street lamps

LED street lamps require very low power supply voltage. Normally, the power supply is used to convert the AC power supply to the DC power supply. This makes the LED street lamp itself without lightning protection. Therefore, to solve the problem of LED street lighting lightning protection, it is necessary to add a street lighting lightning protection module, which can effectively help LED street lighting lightning protection.
