Abstract

Provided is an LED lamp circuit, comprising an LED luminous component circuit, a rectifier circuit, and an output control circuit coupled between the LED luminous component circuit and the rectifier circuit. The LED luminous component circuit comprises at least one light-emitting diode. The rectifier circuit is configured to output a rectified voltage to the LED luminous component circuit. The output control circuit comprises a voltage regulator circuit and a control switch circuit. The voltage regulator circuit comprises a thermosensitive device and a voltage divider connected in series. The thermosensitive device can regulate the control voltage at both ends of the control switch circuit. To protect the LED lamp, the control switch circuit disconnects when the control voltage is less than the threshold voltage of the control switch circuit.
