Classification: CPC H | IPC H

Claim 20:
21. The dummy load control method according to claim 20, wherein
the voltage at one end of the capacitor being less than a first turn-on voltage when the power supply input end is connected to the triac dimmer, thereby enabling the dummy load module to be turned on when the power supply input end is connected to the triac dimmer and the input voltage of the power supply input end is between the zero voltage and a predetermined first power supply voltage comprises:
the voltage at the one end of the capacitor being less than the first turn-on voltage of the first switch when the power supply input end is connected to the triac dimmer, so that the first switch is turned off,
the second switch being turned off when the input voltage of the power supply input end is between the zero voltage and the first power supply voltage, and
the first switch and the second switch being both turned off, so that the dummy load module is turned on; and
the voltage at the one end of the capacitor is greater than the first turn-on voltage when the power supply input end is not connected to the triac dimmer, thereby enabling the dummy load module to be turned off when the power supply input end is not connected to the triac dimmer comprises:
the voltage at the one end of the capacitor being greater than the first turn-on voltage of the first switch when the power supply input end is not connected to the triac dimmer, so that the first switch is turned on, and
the first switch being turned on, so that the dummy load module is turned off.
