Abstract
The present application discloses a lighting control circuit, a lighting control method, and a lighting circuit. The lighting control circuit includes at least a protocol conversion circuit, and a driving signal generation circuit. The dimming selection circuit stores an input data signal as multi-channel digital signals. The driving signal generation circuit controls an off time of a main power transistor according to a first dimming signal derived from the multi-channel digital signals in a first dimming mode, and controls an off time of the main power transistor according to a reference signal derived from the multi-channel digital signals and an output feedback signal in a second dimming mode. The lighting control circuit according to the present disclosure stores the input data signal as multi-channel digital signals, and the circuit can be configured with different dimming modes according to the protocol alone to improve the circuit flexibility.
