Wireless controlled lighting system with shared signal path on output wires
First Claim
1. A lighting system comprising:
- first and second sets of power terminals;
a power stage comprising a power converter configured to provide power across the first set of power terminals, and a controller configured to regulate the power provided by the power converter;
a load stage coupled to the second set of power terminals, wherein the power provided across the first set of power terminals is received by the load stage and deliverable to a load comprising one or more lighting devices;
the load stage further comprising a dimming control signal receiver coupled across the second set of power terminals and configured to receive an encoded dimming control signal; and
the power stage further comprising a dimming control signal decoder coupled across the first set of power terminals, and effective to deliver a decoded dimming control signal to the controller.

Abstract
A lighting system includes circuitry to provide wireless LED driver or fluorescent ballast control without requiring changes to existing wiring setups. A power stage includes a power converter coupled across a first set of power terminals. The first power terminals are coupled to a second set of terminals via the wiring. A load stage is coupled to the second power terminals, wherein power provided across the first set of terminals is received by the load stage and deliverable to lighting devices. The load stage further includes a dimming control signal receiver coupled across the second set of power terminals and configured to receive an encoded dimming control signal. The encoded signal is transmitted across the wiring setup, wherein the power stage further includes a dimming control signal decoder coupled across the first set of power terminals and effective to deliver a decoded dimming control signal to the controller.

20. A method of providing wireless dimming control in a lighting system, the method comprising:
-
receiving an encoded wireless dimming control signal in an isolated receiver circuit associated with a load stage for the lighting system; transmitting the encoded control signal across a first set of power terminals to a decoder associated with a power stage for the lighting system; decoding the encoded dimming control signal; generating a power output for a load comprising one or more lighting devices based on a level of the decoded dimming control signal; and transmitting the power output for the load across the first set of power terminals and to the load stage.
