what should attention of Lightning Protect of LED Street Light ?
Today, LED street light have developed in China for nearly ten years, including power supply, heat dissipation technology, optical technology and so on.
Some basic technical problems of LED street lamps have not been solved in our country. For example, the lightning protection problem of LED street lamp is one of the problems to be solved. So why should we do a good job in LED street lamp lightning protection? What do we do?
I. Necessity of LED the lightning protection of street lights,
Lightning strikes are electrostatic discharges, usually bringing tens of millions of volts of voltage from the cloud to the ground or another cloud. During transmission, lightning generates electromagnetic fields in the air, produces several kilovolts (i.e. surges) of power lines, and produces inductive currents hundreds of miles away. These indirect attacks usually occur on outdoor exposed wires, such as street lamps. Traffic lights and base stations and other equipment emit surges. The surge protection module directly faces the surge interference from the front power line of the circuit. which transmits or absorbs surge energy and minimizes the threat of surge to other working circuits, such as LED AC/DC power supply units in lighting devices, for led street light, led outdoor lighting.
For LED street lamps, lightning generates inductive surges on the power cord. This surge of energy creates a shock wave on the wire, that is, a shock wave. surge is transmitted through this induction. The outside world is booming. the wave will generate a tip on a sine wave on a 220 v transmission line. As the tip enters the street lamp, it will damage LED street lamp circuit.
II. Lightning protection measures for LED street lamps
LED streetlights require a small supply voltage. Usually, the power supply is used to convert AC power to DC power. which makes the LED street lamp itself without lightning protection. Therefore, to solve the problem of LED street lamp lightning protection, it is necessary to add a street lamp lightning protection module, which can effectively help LED street lamp lightning protection.
