Lighting circuit and synchronization method thereof

The present invention relates to a lighting circuit. The lighting circuit comprises: an AC power supply; a first LED light emitting assembly and a second LED light emitting assembly; a first driving circuit connected between the alternating current power supply and the first LED light-emitting assembly; a second driving circuit connected between the alternating current power supply and the second LED light-emitting assembly; and a control signal generating device which can detect the time difference of starting currents of the first LED light-emitting assembly and the second LED light-emitting assembly correspondingly obtained by the first driving circuit and the second driving circuit, and supplying power to the first driving circuit/the second driving circuit which obtains the starting current in advance in a delaying manner so as to realize synchronous lightening of the first LED light-emitting assembly and the second LED light-emitting assembly. 本发明涉及一种照明电路，包括：交流电源；第一LED发光组件和第二LED发光组件；第一驱动电路，连接于所述交流电源和所述第
