ABSTRACT:
A sign board lighting control system for remotely controlling the lighting of a plurality of sign boards includes a radio transmitting device at a central location, and a radio receiving device and a lighting control unit at each sign board location. During set-up of a sign board, programming signals designating the mode of operation and the location of the sign board are transmitted by radio to the control unit associated with each sign board. Subsequently, timing signals containing a multiple-digit computer generated code designating the time of day and the time of sunrise and sunset on a particular day within particular latitudinal zones are transmitted by radio to the control units of all sign boards. Each lighting control unit interprets and responds to the timing signals in accordance with previously received programming signals to control the illumination of the sign board in accordance with a predetermined lighting protocol.
