ABSTRACT:
A remotely controlled dimming solid state ballast system for gas discharge lamps adapted to respond to external control signals is disclosed which includes the ballast itself along with integral controls for interfacing with an external addressing control system, which may be a powerline carrier system. The external control system includes a signal receiver for receiving, and recognizing remotely transmitted control signals addressed to said ballast. An output device is provided for generating an output control signal modulated in response to the control signals to provide the desired control setpoint of the lamps controlled by the ballast or to turn the lamps on or off.
