Powerline communication control of light emitting diode (LED) lighting fixtures
First Claim
1. A powerline communication control system for controlling a lighting fixture, comprising:
- a master controller, comprising;
a conventional dimmer interface configured to interconnect with a plurality of different conventional dimmer controllers;
a lighting control processor in communication with the dimmer interface, the lighting control processor generates a lighting unit command output in a lighting unit system command format in response to an indication of a user-adjusted setting of any interconnected plurality of different conventional dimmer controllers received from the conventional dimmer interface; and
a power distribution system interface in communication with the lighting control processor and configured to interconnect with a power distribution system, the power distribution system interface superimposes the lighting unit system command output onto the power distribution system when connected thereto; and
a plurality of lighting fixture controllers, each controller comprising;
a command receiving interface configured to interconnect with the power distribution system, the command receiving interface separates the lighting unit system command output from the power distribution system when connected thereto;
a slave control processor in communication with the command receiving interface and converts the received lighting unit system command output into a corresponding lighting unit control command; and
a lighting unit interface for providing the lighting unit control command to its respective lighting unit to control the respective lighting unit in response to the user-adjusted setting of any one of the interconnected conventional dimmers.

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.
