MODULAR WIRELESS LIGHTING CONTROL SYSTEM USING A COMMON BALLAST CONTROL INTERFACE

摘要

Disclosed is a modular lighting system that incorporates wireless technology and a standard interface. The lighting system may be installed in new buildings or retrofitted into existing buildings in such a way that provides many lighting configurations and programmability options while minimizing the amount of new wiring. The system includes a transceiver that controls one or more lamps using a dimming ballast or a relay and a low cost ballast. The dimming ballast, and the relay (if used) provide low voltage power to the transceiver over a cable having a standard interface, such as an RJl 1 telephone jack. The transceiver provides on/off switching control and dimmer control, through the same cable, to the relay or dimming ballast. The transceiver can be located in the same room as the lamps it controls, or remotely located. A central computer or controller can control multiple transceivers over a wireless link.
