Abstract: A projection illumination fixture includes luminescent light tubes lined with an emulsion coating of titanium dioxide and phosphors for producing an appropriate mixture of highly scattered red, blue and green wavelengths of sustained luminescent light emission, a reflector housing for reflecting scattered rays of emitted luminescent light toward an aperture, a catadioptric lens for collecting and redirecting luminescent light rays reaching the aperture into and through a light snoot or barrel and a large area projection (magnifying) Fresnel lens at the end of the light snoot or barrel for directing and spreading the emitted light to fill an illumination field with directional divergent light ideal for dimensionally ‘painting’ talent and objects positioned and moving within the illumination field.

Abstract: A luminaire for luminescent light sources includes: (i) an extruded tubular `U`-shaped housing having a longitudinal external male dovetail shoulder on one side, a longitudinal external female dovetail channel on its other side, a longitudinal external female dovetail channel on the bottom, two terminating longitudinal `C`-channel tracks one along the edge of each side leg, and two diametrically opposing interior longitudinal `C`-channels; (ii) a mounting plate secured by screws received within the internal `C`-channels at each end of the housing; (iii) electrical power mounting sockets secured to the end plates; (iv) luminescent light tubes mounted in the sockets extending longitudinally within the housing; (v) a reflector surface curling around the luminescent light tubes within the housing; (vi) retractable endcaps resiliently secured by spring biased screws to each endplate closing each end of the housing; and a longitudinal curved transparent lens element having beaded side edges shaped for capture by an

Abstract: A luminescent fixture for providing sustained illumination suitable for television, video and film production includes a plurality of parallel mercury vapor luminescent lamp tubes aligned in close proximity in a common plane bisecting an acute concave angle defined by high reflectivity facing surfaces of a pair of longitudinal reflector panels. A plurality of separate electronic ballasts located at the base of the extending reflector panels provide a plurality of unsynchronized electrical current pulse trains each for exciting pulsed ultraviolet light emissions from Hg vapor within a particular set of lamp tubes at a rate sufficient to excite/stimulate sustained luminescent light emission from the phosphors in the emulsion coating lining the interior of the light tubes, i.e.
