LIGHTING APPARATUS

Abstract: a lighting apparatus includes a rectifier bridge circuit, a light source, a led controller, a dimmer detector circuit and a bleeder circuit. the rectifier bridge circuit converts an ac power to a dc power. the led controller for generates a plurality of driving currents based on the dc power to respectively control plurality of led modules of different types. the dimmer detector circuit detects whether a dimmer is coupled to the lighting apparatus. the bleeder circuit is coupled to the dimmer detector circuit. the bleeder circuit is configured to be turned on when the dimmer detector circuit detects that the dimmer is coupled to the lighting apparatus for fixing a signal distortion for power input to the led controller. the signal distortion is caused by the dimmer.
