led street lighting manufacturers to introduce you Hengyuan current
led street lighting manufacturers To make the LED driver circuit presents constant current characteristics, look from the output end of the driver circuit, the output impedance must be high. Work, the load current is also passed through this output impedance, if the drive circuit from the buck, rectifier and filter plus DC current source circuit or a common switching power supply and resistance circuit, it must also consume a lot of active power Power, so the two types of drive circuit to meet the basic premise of the constant current output, the efficiency is not high. The correct design is the use of active electronic switching circuit or the use of high-frequency current to drive the LED, the use of these two programs can make the drive circuit to maintain a good constant current output characteristics of the premise, still has a high conversion efficiency
