description The present disclosure provides a dimmer control circuit, a dimmer control method and a lighting device. The dimmer control circuit includes: a dimming output end configured to connect to a dimmer, a load terminal configured to connect to a load, a detection-control module, and a current holding module. An input end of the detection-control module is connected to an output end of the dimmer. An output end of the detection-control module is configured to: control the current holding module to connect to the load terminal when the dimming output end is connected to a SCR-based leading-edge phase cut dimmer, and control the current holding module to disconnect from the load terminal when the dimming output end is not connected to the SCR-based leading-edge phase cut dimmer. The current holding module is configured to supply a holding current to the SCR-based leading-edge phase cut dimmer connected to the dimming output end.
