LIGHT DRIVING SYSTEM AND METHOD

摘要

A light driving system is provided that includes a light dimmer that receives an AC input signal and provides a dimmer output signal that includes a fast rising leading edge, a rectifier that receives the dimmer output signal and provide a rectified dimmer output signal and an AC/DC converter that filters the rectified dimmer output signal to provide a DC input signal that is employed to drive a light. The light driving system also comprises a protection circuit that limits current to the AC/DC converter during the fast rising leading edge of the dimmer output signal.
