Abstract
A lighting apparatus includes a light source, a bridge circuit, a voltage node, a filter circuit, a dimmer check circuit and a control circuit. The light source includes a LED module. The bridge circuit generates a DC power at a voltage node by converting an AC power. The filter circuit is connected to the voltage node for converting the DC power to a driving current to the LED module. The dimmer check circuit is coupled to the voltage node for generating a dimmer check signal by detecting whether a wall dimmer is electrically coupled to the lighting apparatus. The control circuit adjusts a setting of the filter circuit according to the dimmer check signal.
