Claim 3:
4. The dummy load control circuit according to claim 1, wherein the first switch comprises a first control end, the first switch is connected to the dummy load control end, and the first switch control module is connected between the power supply input end and the first control end,
wherein the first switch is controlled by the first switch control module, so that the first switch is turned off when the power supply input end is connected to a triac dimmer, and is turned on when the power supply input end is not connected to the triac dimmer comprises:
a 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 a first turn-on voltage of the first switch when the power supply input end is connected to the triac dimmer, and thus the first switch is turned off; and so that 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, and thus the first switch is turned on.
