Abstract
The present disclosure provides a dummy load control circuit and a lighting device. The dummy load control circuit and a dummy load module are connected in parallel with a power supply input end and the dummy load control circuit includes a first switch circuit having a first switch control module so the first switch is controlled to be turned off when the power supply input end is connected to a triac dimmer, and turned on when the power supply input end is not connected to the triac dimmer, a second switch circuit having a second switch control module controlling on/off of the second switch, and a constant voltage source providing a constant voltage so the dummy load module is turned on when the first switch and the second switch are turned off, and turned off when the first switch and/or the second switch are turned on.
