Claim 6:
7. The dummy load control circuit according to claim 6, wherein the voltage of the first control end is controlled by the first switch control module, so that the voltage of the first control end is less than the first turn-on voltage when the power supply input end is connected to the triac dimmer, and the voltage of the first control end is greater than the first turn-on voltage when the power supply input end is not connected to the triac dimmer comprises:
controlling, using the input voltage of the power input end, the voltage of the charge/discharge control end through the charge/discharge control module, so as to control on/off of the third switch, thereby controlling a charge/discharge time of the capacitor, so that the voltage at the one end of the capacitor is less than the first turn-on voltage when the power supply input end is connected to the triac dimmer, and is greater than the first turn-on voltage when the power supply input end is not connected to the triac dimmer, and
wherein the capacitor is charged when the third switch is turned off, and discharges when the third switch is turned on.
