It is reported that LED street lights need to be driven by the power supply to turn the high voltage of the mains into low voltage, and this part has a large test of the power supply performance, such as poor heat dissipation, use in extremely cold areas with low temperature environment, or long When the time is running, etc., the power supply may malfunction, so the stability of the power supply needs to be improved. Xiao Zhiyong, vice president of sales at BYD, said.
However, some insiders pointed out that compared with light source devices, domestic enterprises actually have the ability to do a good job of power supply. The key is that the cost cannot be compressed too much. It is necessary to use good quality devices.
Usually, if a street lamp fails, the enterprise needs to first detect it and check various faults. If the drive power fails, the power supply needs to be removed and sent back to the power supply company.It is reported that the budget for the cost of LED street lamp repair is about 2, but for some products with poor quality, the cost of repairing may reach 5. This installation and disassembly cost is very high, which will cause a heavy burden on street lamps. If the quantity is large, even a company will be dragged down, so the quality of the power supply is critical. An engineer with years of experience in driving power development said frankly.
