Light-emitting diode (LED) is an ideal energy-efficient lighting source. Because of its unique light-emitting principle, LED needs constant current power source driver. The drive circuit to a large extent determines the efficiency of the energy efficiency of LED lighting. This paper analyses the efficiency of PCC BUCK circuit of LED lighting driver using simulation and experimental method, as well as compares the energy consumption of the various parts of the circuit. Following analysis, this paper gives specific measures to improve the drive efficiency.
