The utility model discloses an electric lamp control circuit. The circuit comprises a live wire end, a zero wire end, a first diode, a second diode, a third diode, a fourth diode, a fifth diode, a first capacitor, a silicon controlled rectifier, a first resistor, a second resistor, a third resistor, a fourth resistor, a photoelectric coupler, a PWM module and a wireless module. The PWM module is in communication connection with the wireless module; the output end of the PWM module is connected with the cathode of the photoelectric coupler through a fourth resistor, the anode of the photoelectric coupler is connected with the direct-current power supply end, the lower end of the second resistor is connected with the cathode of the fifth diode, the upper end of the first capacitor and the control end of the silicon controlled rectifier, and the PWM module is used for generating PWM waves to control the conduction angle of the silicon controlled rectifier. The brightness of the electric lamp is changed by changi
