Why does the Led street lights Manufacturers(CLASSIC) power supply have a constant flow? The characteristics of the LED lighting material determine its environmental impact, such as temperature changes, LED current will increase, the voltage will increase, and LED current will increase. Exceeding the rated current will greatly shorten the service life of the LED lamp bead.
The LED constant flow changes in environmental factors such as temperature and voltage to ensure that the operating current value does not change. Constant current accuracy on the LED street light power supply market Some power supply constant current accuracy is poor, just like the popular recommended scheme on the market, such as constant current scheme, the error reaches ±8%, and the constant current error is too large. The general requirement is ±3%. According to the 3% design. Fine-tuning of production power, achieving ±3% error.
LED street light power supply operating voltage general LED recommended operating voltage is 3. $. 5V, after testing, most of the work is at 3.2V, so it is more reasonable to calculate by 3.2V. The total voltage of the n-Lamp beads is $liter. $ N.LED Street Light Power Board Series - How wide is the parallel and wide voltage? In order to operate the LED street light power over a wide range of input voltage ranges ac85-265v, the LED series-parallel method is very important.
In order to obtain a larger power factor, the series of lamp beads should not be too small, otherwise, the optimal working condition will not be achieved. The number of series and the number of secondary winding turns on the isolated power supply must meet the power output power. The smaller the operating current of the electronic component in the rated voltage operating current range, the longer the life and the shorter the life. LED street light power beads are sensitive to exchange weight, the higher the traffic, the worse the light comfort.
