Claim of US Patent No. 10,462,879

1. A method for controlling a light emitting diode (LED) lighting unit via an LED lighting unit's power distribution system, the method comprising:supplying operational power to the LED lighting unit via the LED lighting unit's power distribution system;
a user adjusting at least one conventional LED dimmer associated with the LED lighting unit;
at least one master controller coupled to the power distribution system and the at least one conventional LED dimmer, the master controller:
receiving, at a lighting control command processor, a lighting unit control input from the at least one conventional LED dimmer and generating corresponding lighting unit command outputs in a lighting system command format in response to an indication of the user-adjusted setting of the at least one conventional LED dimmer; and
superimposing, at a power distribution system interface, 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, and
at least one device controller coupled to the at least one master controller and the LED lighting unit, each device controller:
receiving at a command receiving interface, the lighting command signal, separating the lighting command signal from the power signal, and generating corresponding lighting control commands,
converting, at a lighting control processor, the received lighting control commands into lighting unit control commands; and
providing, at a lighting unit interface, the lighting unit control commands to the LED lighting unit to control the LED lighting unit in response to the user-adjusted setting of the at least one conventional LED dimmer.
