摘要

system for implementing dimming based on the signal from the solid state lighting module, and method for providing dimming based on the signal from a LED module a system for implementing dimming based on the Mains voltage of a solid-state lighting module includes a transformer, a mains sensing circuit, and a processing circuit. The transformer includes a primary side connected to a primary side circuit and a secondary side connected to a secondary side circuit, the primary and secondary side circuits being separated by an isolation barrier. the mains sensing circuit receives a rectified mains voltage from the primary side circuit and generates a mains sensory signal indicating the amplitude of the rectified mains voltage. the processing circuit receives the mains sensory signal from the mains sensory circuit through the isolation barrier, and outputs a dimming reference signal to the secondary side circuit in response to the mains sensory signal. The light emitted by the solid state lighting module connected to the secondary side circuit is adjusted in response to the dimming reference signal emitted by the processing circuit. 1/1
