Abstract

A powerline communication control system for controlling a lighting unit, such as an LED lighting unit, including a master controller for receiving lighting unit control inputs from a lighting controller and generating corresponding lighting unit command outputs in a lighting system command format and transmission mode and superimposing the lighting unit command outputs onto the power distribution system and at least one lighting slave unit for receiving the lighting command signal, separating the lighting command signal from the power signal and for providing lighting unit control commands to the at least one lighting unit to control illumination thereof.

Claims

1. A slave controller for controlling a light emitting diode (LED) lighting unit via the LED lighting unit'"'"'s power distribution system for supplying operational power to the LED lighting unit, the slave controller comprising:

a command receiving interface connected to the power distribution system configured to receive a lighting command signal generated by a master controller corresponding lighting unit command outputs in a lighting system command format in response to an indication of a user-adjusted setting of any one of a plurality of different conventional dimmer lighting controllers, separate the lighting command signal from the power signal, and generate corresponding slave control commands;

a slave control processor configured to covert the received slave control commands into lighting unit control commands; and

a lighting unit interface configured to provide the lighting unit control commands to the at least one LED lighting unit to control the at least one LED lighting unit in response to a user-adjusted setting of any one of different conventional dimmers.
