Managing SSL fixtures over PLC networks

摘要

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.

1. A power line carrier network system for controlling a solid-state luminary fixture using a power distribution network that distributes electrical power, comprising:
a local controller comprising
a processor configured to receive and process a control signal to control the solid-state luminary (SSL) fixture, an SSL lighting node comprising
a power converter to receive input power from a PLC network, andreceive the control signal to control a power convertor to modulate the input power to provide a level of illumination specified by the control signal, a power line carrier (PLC) modem coupled to the PLC network configured to
extract the control signal from the PLC network;decode the control signal;route the control signal to an SSL lighting node interfaced with the PLC network;receive feedback from the power converter;encode the feedback for transmission on the PLC network; andinject the feedback onto the PLC network.
