Solar Street Lamp: an Important Measure and Analysis of Street Lamp Lightning Protection

Today, the development of solar street lamps in rural China has a history of nearly ten years, including power supply, power supply, heat dissipation technology, optical technology, etc., and there are new breakthroughs every year. Some basic technical problems of LED street lamps have not been solved in China. Lightning protection 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 lamps? What should we do?1 Necessity of lightning protection of LED rural solar street lamps

Solar Street Lamp: an Important Measure and Analysis of Street Lamp Lightning Protection 1

Lightning strikes are electrostatic discharges that usually transmit millions of volts from one cloud to the ground or another. During transmission, lightning generates electromagnetic fields in the air, thousands of volts (i.e. surges) on power lines, and induces currents hundreds of miles away. These indirect attacks usually occur on outdoor exposed wires, such as street lamps. Equipment such as traffic lights and base stations send out surges. The surge protection module directly faces the surge interference from the power line at the front end of the circuit. It transmits or absorbs surge energy to minimize the threat of surge to other working circuits, such as AC / DC power supply unit in LED lighting equipment.

For LED rural solar street lamps, lightning will produce induced surge on the power line. This surge of energy produces a shock wave on the wire, that is, a shock wave. Surge is transmitted through this induction. The outside world is proliferating. The wave will produce a tip on the sine wave on the 220 volt transmission line. When the tip enters the street lamp, the LED street lamp circuit will be damaged.Therefore, the lightning protection of LED street lamp will be conducive to its service life, which is necessary at present.Lightning protection measures for LED rural solar street lamps

Rural solar street lamps need smaller power supply voltage. Generally, the power supply is used to convert AC to DC. This makes the LED street lamp itself without lightning protection. Therefore, in order to solve the lightning protection problem of LED street lamps, it is necessary to add street lamp lightning protection module to effectively help LED street lamps.
