ABSTRACT:
A plurality of spaced ceiling mounted fixtures or other controllable electrical appliances have wide angle radiation detectors mounted within each fixture and wired internally of the fixture to a dimming circuit or to a ballast. The radiation detectors have sensitivity over a wide angle and are fixed over a small opening in the fixture. A narrow beam radiation transmitter selectively illuminates one of the radiation detectors without illuminating the others. The dimming circuits or ballasts within the fixtures can be further controlled by external dimmers, occupancy sensors, timeclocks, photosensors and other types of input devices.
