How much is the wholesale price of solar street lamps

Today, LED street lamp has been development in China has a history of nearly ten years, including power supply, power supply and cooling technology, optical technology, every year has the new breakthrough. Some LED street lamp based technical problems in our country has not yet been solved. Lightningproof of the column, such as the LED street lamp is

today, LED lights in China has developed for nearly 10 years, including power supply, power supply, cooling technology, optical technology, etc. , every year has the new breakthrough. In China, some basic technical issues led street light have not solved. LED lights of the lightning protection is one of the problems that need to be solved. So why do we want to do a good job of lightning protection of LED street lights? How are we going to do it again? A, LED street light the necessity of the lightning protection lightning is electrostatic discharge, and usually will be millions of volts from cloud to ground or another piece of cloud. In the process of transmission, the lightning in the air to generate electromagnetic fields in the body, produce a few kv on transmission line ( The surge) , and the induced current in hundreds of miles away. These indirect attack occurred often in outdoor exposed wires, such as street lamps. A surge of traffic lights and the base station. Surge protection module directly to front end circuit transient interference of power supply cord. Transmitted or absorb the surge of energy, it will surge of other work to minimize the threat of circuit, such as led lighting equipment in ac/DC power supply unit. For led street lamp, electrical wiring on the lightning induced transient. This energy surge in wires produced shock wave, the shock wave. Surge through the induction. The outside world is spreading. The wave will tip in 220 v on the sine wave of a transmission line. When the suction head into the street lamp, can damage the led lamp circuit. Therefore, at present it is necessary for the LED street lamp for lightning protection, in order to prolong its service life. Second, led street lamp led street lamp need a lightning protection small power supply voltage. Usually, the power supply is used to convert ac power to DC power supply. This makes the led street light itself has no lightning protection. Therefore, in order to solve the problem of led street lamp of lightning protection, lightning protection module, it is necessary to add a street lamp effectively contribute to the led street lamp of lightning protection.
