In order to make the LED drive circuit exhibit constant current characteristics, the output internal impedance must be high when viewed from the output end of the drive circuit. During operation, the load current also passes through the output internal impedance. If the drive circuit consists of buck, rectification and filtering, plus DC constant current source circuit or general-purpose switching power supply plus resistance circuit, it must consume a lot of active power. Power, so the two types of drive circuits under the premise of basically meeting the constant current output, the efficiency is impossible. The correct design scheme is to use an active electronic switching circuit or to use high-frequency current to drive the LED. The above two schemes can make the driving circuit still have high conversion efficiency while maintaining good constant current output characteristics.
