Abstract
Managing solid-state luminary (SSL) fixtures over power line carrier (PLC) networks is described herein. Devices provided in this description include SSL arrays, and converter circuitry coupled to drive the SSL arrays. More specifically, the converter circuitry is adapted to convert input voltage received from a power distribution network into a level suitable for driving the SSL arrays. The devices also include (PLC) modems for coupling to PLC networks, and coupled to the converter circuitry. In particular, the PLC modems interface the converter circuitry to the PLC networks.
Claims20
A device comprising:
- a solid-state luminary (SSL) array;
- converter circuitry coupled to the SSL array and adapted to convert input voltage received from a power distribution network into output power for driving the SSL array;
- and
- a power line carrier (PLC) modem coupled to the power distribution network and configured to receive a control signal over a PLC network on the power distribution network, determine if the control signal is addressed to the device, and upon determining that the control signal is addressed to the device, decode the control signal and configure the converter circuitry to drive the SSL array to an illumination level based on the control signal, wherein the PLC modem is further configured to receive feedback from the converter circuitry, encode the feedback for transmission on the PLC network, and inject the feedback onto the PLC network.
