LED street lamp power supply is a key part of the LED street light, when we choose the LED street light, the power supply must conform to the standard? Light pole manufacturers to introduce the below: first, the LED street lamp power supply must be a constant current power supply LED street lamp lighting the characteristics of raw materials determines its impact on regional environment. For example, if the temperature changes, the LED current will increase. In addition, the LED voltage will increase. If long-term operation exceeds the current, the use of the LED lamp bead period will shorten. LED street lamp power supply, constant current and changes in environmental factors such as temperature and voltage ensure its work in the current. Two sales, LED street lamp power supply constant current power supply precision constant current precision of some power supply on the market, plus or minus 8% deviation is likely to arrive, and the constant current deviation is too large. Standard is plus or minus 3%. According to the design of 3%. Face the production power be fine-tuning, to keep the deviation of plus or minus 3%. Three, LED street lamp power supply working voltage of common LED recommend the working voltage of 3. 0 - 3. 5V。 After testing, the vast majority of the work in 3. 2 v, and therefore on the basis of 3. 2 v calculation is reasonable. N the total voltage series lamp bead = 3. 2*N. Of the four, LED street lamp power supply suitable work, for example, in the current work in the current rating of the LED street lamp is 350 mah. Some LED street lamp manufacturers use it at the beginning, the design of 350 ma. In fact, the electricity work flow quantity of heat is very serious. After multiple comparison test, the design of 320 ma is more appropriate, to minimize the heat and more electrical energy can be converted to visible light.
