Abstract:
A controller that monitors a rectified voltage and detects whether the rectified voltage comes from a TRIAC dimmer or an on/off switch dimmer is disclosed. The controller controls dimming of a light source according to the rectified voltage if the rectified voltage comes from the TRIAC dimmer. The controller controls dimming of the light source according to an operation of the on/off switch dimmer if the rectified voltage comes from the on/off switch dimmer.
