ABSTRACT:
A plurality of spaced ceiling mounted fixtures or other controllable electrical appliances have 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 have elongated plastic radiation conduction rods which extend to or beyond the plane of the lens of the fixture to be located free of shadow effects of reflections of the fixture lens. A flexible end light fiber optics can be used in place of the acrylic rods. A narrow beam radiation transmitter selectively illuminates one of the rods or end light fiber optics 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. The radiation detector and ballast can occupy a common housing and share the same power supply and circuit board. The microcontroller for the radiation detector operates with a 4 of 4 voting mode until a valid signal is detected to switch the system to a 3 of 4 voting mode. A novel mounting adaptor for mounting a visible light fiber optic cable is disclosed with the visible light fiber optic cable conducting infrared radiation for up to 24 inches.
