Abstract
A light dimming system is disclosed. The system includes an alternating current (AC) power source having a main line carrying an AC mains voltage and a neutral line, a lighting control module connected to the main line and the neutral line of the AC power source, wherein the control module provides a mixed output signal that combines the AC mains voltage with an encoded dimming control signal, and an LED lighting fixture (“luminaire”) that is connected to the mixed output signal of the lighting control module and is under control of a line decoder module, wherein the line decoder module decodes the mixed output signal into the AC mains voltage and a dimming control signal for consumption by the luminaire.
