Abstract
A lighting control system, including a TRIAC dimmer, a wireless control apparatus, and a lighting apparatus. The lighting apparatus includes a rectifier circuit, a TRIAC dimming detection circuit, a dimming constant-current circuit, and a controller connected to the TRIAC dimming detection circuit and the dimming constant-current circuit. The controller is configured to, control the dimming constant-current circuit to perform dimming on the lighting load based on a brightness control signal, in response to receiving the brightness control signal sent by the wireless control apparatus, and control the dimming constant-current circuit to restore a default state to stop the wireless control apparatus from limiting the dimming constant-current circuit, in response to the TRIAC dimming detection circuit determining that a first preset operation is performed on the TRIAC dimmer.
