Abstract: A line of recessed low-glare lighting fixtures, known as HITC (hole-in-the-ceiling), provide an authentic architectural built-in appearance. A mounting unit is cast in plaster material with a vertical duct extending upwardly from a light-exit opening in a horizontal face flange that becomes plastered in place in the ceiling. The duct supports a light source and associated components above, producing a light beam of designated beam width, typically +/?45 degrees. From any room viewpoint outside the light beam, the only component of the fixture that is visible is the mounting unit, of which all visible regions, both internal and external, are made to have finish, appearance and texture that match and blend in harmoniously with the surface of the surrounding ceiling.

Abstract: A line of recessed low-glare lighting fixtures provides a totally built-in architectural recessed appearance: a special cast mounting unit has a recessed duct portion formed integrally with a flat face flange portion defining a light-exit opening. The face flange portion becomes plastered in place in a wall or ceiling with the duct portion supporting the light source and associated components. In a main embodiment for ceiling deployment, the face flange portion is made square, the light-exit opening and the duct portion can be made circular or rectangular, typically square, In an offset hidden source embodiment, usually wall-mounted with a rectangular light-exit opening to “wash” either a ceiling or a floor region, the recessed duct portion is curved and shaped to serve as a reflector surface for desired illumination distribution. The light source can be incandescent, fluorescent or metal halide, in a selection of wattage ratings. The mounting unit can be cast in different sizes according to wattage ratings.

Abstract: An indirect fluorescent lighting fixture with a self-contained curved reflector is enclosed in a square housing that fits into an inverted T-bar grid cell of a suspended ceiling in place of 2'.times.2' ceiling tile, or it can be permanently mounted in a wall or ceiling. A centrally located fluorescent tube, extending between two opposite sides of the enclosure, is enclosed from view by a U shaped shield. The reflector, disposed above the tube directing light downwardly into a targeted room region, can be made with a single concave curvature for narrower "spotlight" applications or with a dual concave curvature for wider field applications. The reflector is held in place in a self-stressed condition between a pair of end channels such that its shape can be controlled by varying its length. The illumination pattern can be controlled and modified by a combination of shaping the reflector's curvature and selection of its reflective surface properties.

Abstract: For recessed lighting fixtures, particularly those mounted in ceilings, the present invention provides an easily attached removable accessory device for deflecting a portion of the light path in a selected direction that differs from the original direction, e.g. deflecting downwardly directed light to a substantially horizontal direction. A mirror assembly, typically having two round flat reflecting surfaces, one on each side, is supported by a wire hanger element via an axle portion passing diametrically through the mirror; the hanger element has a pair of hooks at the upper ends of two side wires that engage the recessed light fixture at any desired orientation around the axis of the fixture. The mirror can be tilted to any angle, and is retained at the selected tilt angle by friction of the wire axle being clamped between of a pair of resilient pads.

Abstract: A fluorescent indirect lighting fixture of the hidden source offset reflector type incorporates a novel reflector mounting system which provides advantages of extended uniform "wash" illumination with unusual concealment of the light source from direct view, along with extremenly easy reflector installation and replacement. The reflector, formed to the required special curvature from a thin sheet of suitable metal such as high purity aluminum, is sprung into place between two opposite edges of a window opening in the metal fixture housing in a tongue-and-groove type engagement along the two edges where it is retained in place by the resilience of the reflector with no need for adhesives, screws or other fastenings. Illumination coverage and lamp concealment are both maximized by configuring the reflector and its mounting system uncompromisingly such that both of the straight end regions of the curved reflector extend smoothly and fully to a plane flush with the surrounding ceiling or wall surface.

Abstract: An improved fluorescent indirect lighting fixture has its light source concealed from normal view by locating the lamps in a partially wrapped-around region to one side of an offset reflector, which is shaped in a special concave curvature to produce uniform "wall wash" illumination. A producible high quality reflective surface with required curvature maintained by a rigid, accurate reflector assembly is achieved by utilzing a thin flexible reflective lining of high purity aluminum conformally laminated against a rigid extruded aluminum reflector body of required curvature. Two-piece end plates provide lamp socket mountings, integral wiring conduits, reflective inner end surfaces, decorative trim at light-exit window ends and reflector body reinforcement.
