    摘要： The application discloses a power supply circuit for control circuit of LED lighting, the LED lighting comprising a plurality of LED light sources connected in series and a control switch for controlling on and off of current path of the LED light sources. The power supply circuit is characterized in that it comprises a first PNP transistor whose collector is coupled to power input of the control circuit, emitter is coupled to a first node between a first group of LED light sources and a second group of LED light sources upstream the control switch, and base is coupled to a second node between the control switch and the second group of LED light sources, such that when the control switch controls the current path to close, the first PNP transistor is on and when the control switch controls the current path to open, the first PNP transistor is off; a second NPN transistor whose base is coupled to emitter of the first PNP transistor, emitter is coupled to the power input of the control circuit, and collector is coupled to power input of the plurality of LED light sources. The application further relates to LED lighting comprising the power supply circuit.
