Powerline communication control of light emitting diode (LED) lighting fixtures
First Claim
1. A master 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 master controller comprising:
- a lighting control command processor configured to receive a lighting unit control input from any one of a plurality of different conventional dimmer lighting controllers and configured to generate 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 the plurality of different conventional dimmer lighting controllers; and
a power distribution system interface configured to superimpose the lighting unit command outputs onto the power distribution system and a power signal present thereon as a lighting command signal according to a lighting unit command transmission mode.

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.
