ABSTRACT:
A method and apparatus are described for a networked lighting system that may be controlled either remotely or locally by a power line communication (PLC) link. The components of the system, addressable lamp ballasts and addressable wall switches, replace their conventional counterparts. The resulting networked lighting system implemented with these components is controlled remotely from a centralized building control center. A particular room may be controlled by the building control center or locally by a wall switch. The invention requires no rewiring of the building's wiring plant, because the addressable components are direct electrical replacements, and installation of the system, therefore, takes a minimum amount of time.
