The LED solar street light industry is not only affected by the global environment, but also has its industry specificity. The LED solar street light power supply is the top priority of the current LED development. For the technical design of the LED solar street light power supply, there are already a variety of solutions and unique design methods. So let's take a look at the selection of LED solar street light power supply. 1Why does the power supply of LED solar street light have to be constant current? The characteristics of LED solar street light material determine that it is greatly affected by the environment. Exceeding the rated current for a long time will greatly shorten the service life of the LED lamp beads. The constant current output of the LED power supply can ensure that the LED light source works stably when environmental factors such as temperature and voltage change. 2 About the constant current accuracy of the LED solar street light power supply In addition to the heat dissipation performance of the lamp itself, the constant current accuracy of the LED power supply output plays a certain leading role in the working life of the LED solar street light. At present, the constant current accuracy of most LED power supplies on the market is plus or minus 8%. We can adjust the constant current accuracy to plus or minus 3% by fine-tuning and selecting high-precision devices, which can greatly improve the stability and performance of LED solar street light. life. Why should the 3LED solar street light power board adopt the design of wide voltage input? Because street lamps belong to the category of outdoor lighting, the environment will be relatively harsh. In order to ensure the long-term and reliable operation of lamps, it is recommended to use a design with a wide voltage input. 4 Which isolated power supply solution should be used? The isolated power supply is to use a transformer to reduce the 220V voltage to a lower voltage through the transformer, and then rectify it into a DC output for power supply. The advantages of the isolated power supply are that it will not pose a threat to the human body, the wide voltage performance is good, and the reliability is high. The non-isolated module has a simple structure and high efficiency, but has poor safety performance. Based on safety requirements, it is recommended to use an isolation scheme for street lamps. 5LED solar street light power supply heat dissipation and waterproofing Because the LED solar street light power supply is affected by its own electrical conversion efficiency during operation, it will generate a large amount of heat, and if it is not dissipated in time, its life and stability will be greatly reduced. Therefore, good LED solar street light power supplies are made of aluminum alloy shells and potted with high-efficiency thermal conductive glue for electronic components, which is easy for power supply to dissipate heat and waterproof performance. We mainly produce and sell outdoor road, square, station, wharf, courtyard and indoor industrial and mining lighting fixtures. Varieties are: solar street light,
