ABSTRACT:
A field-of-operation illuminating fixture with a video camera in the vicinity of a lamp housing for displaying the field. The video signals emitted by the camera are forwarded along with signals for controlling the camera over the same cable that transmits power to the lamps. The cable extends through the mechanism that the housing is suspended from, such as being extended from a ceiling. The cable is in sections connected by rotating contacts in the form of slip rings at the articulations between a suspension boom and arms. Video signals and camera-control signals are modulated before entering the cable by a module in the ceiling-mounted base of the fixture and are demodulated in another module after leaving the cable. The video signals are processed in a separate accessory. The present invention provides a cost-effective design for a field-of-operation illuminating fixture equipped for video and simple modification of fixtures already equipped therewith.
