Abstract: An AC circuit PLC injection module of a PLC-enabled power and data distribution system (300) includes: an AC power input (307) to receive an AC power signal; a PLC transceiver circuit (430/440) to couple a PLC signal onto the AC power signal; an AC circuit (411) to supply the AC power and the PLC signal; and a PLC blocking line filter (450) to filter the PLC signal from passing to the AC power input. An associated method for a system having plural PLC transmitters connected to plural PLC enabled devices via plural AC circuits each associated with one of the PLC transmitters, includes: setting PLC network IDs for each of the PLC enabled devices to a default PLC network ID, and then assigning each of the PLC enabled devices connected to each of the PLC transmitters to a PLC network ID uniquely assigned that PLC transmitter.

Abstract: A method and system are provided for smoothly dimming a solid state light (SSL) source. The method includes measuring a dimming angle (S322) of a voltage received from a dimmer, determining a target brightness (S323) of light to be output by the SSL source corresponding to the dimming angle, determining a current brightness (S324) of light currently output by the SSL source, and determining a slew rate (S325) based on the current brightness and the target brightness. The current brightness of the light currently output by the SSL source is adjusted (S326) to the target brightness using the nonlinear slew rate.
