Abstract: A wall-washer lighting fixture is installed flush with a ceiling surface and directs light horizontally and vertically along adjacent wall surfaces, closely adjacent to the intersection between the ceiling and the wall surfaces in order to reduce to a minimum any shaded area along wall surfaces adjacent the intersection. The lighting fixture includes first lens elements oriented, located and configured for directing light toward first areas of the wall surface, spaced vertically downwardly from the intersection, and a second lens element located vertically lower than the first lens elements and oriented and configured for directing light toward second areas of the wall surface, located between the first areas and the intersection between the ceiling surface and the wall surface, so as to illuminate the wall surface more uniformly while reducing to a minimum any shaded area along the wall surface adjacent the intersection.

Abstract: A multifunctional recessed lighting fixture which offers a unique combination of modular parts and unit components which can be assembled in a plurality of possible variations resulting in distinctive appearance of the variants assembled, yet maintaining an appearance of continuity among the recessed lights.

Abstract: An improved optics, recessed lighting fixture specially designed for easy installation into sloped ceilings is described. The improved optics are provided by a novel asymmetrical dome reflector which adapts the fixture to sloped ceilings for directing reflected light to within the natural cone of illumination emitted by a lamp in the absence of a reflector.

Abstract: A lighting fixture having a simplified structure is provided with such benefits as a junction box attached either permanently or releasably to the housing, a full reflector for improved optics, and support means for installation in different ceiling structures. The reflector is positionable within the housing, whereby inexact or inaccurate mounting of the housing to the ceiling structure can be corrected by changing the orientation of the reflector. Also provided are novel junction boxes. In various embodiments, the junction box may contain an L-shaped door, to cover an L-shaped opening which allows the interior of the junction box to be inspected from the bottom after installation. Another embodiment of junction box includes side walls flexibly joined to permit installation and removal of the junction box. Preferably, this latter embodiment is installed in a fixture through the bottom opening through which the reflector, socket, bulb, and the like are installed.

Abstract: A lighting fixture having a simplified structure is provided with such benefits as a junction box attached directly to the housing, a full reflector for improved optics, and support means for installation in different ceiling structures. A bulb or lamp is disposed in a socket which is attached to the reflector such that the lamp is disposed entirely within the volume of the reflector. Additionally, the reflector is positionable within the housing, whereby inexact or inaccurate mounting of the housing to the ceiling structure can be corrected by changing the orientation of the reflector. Accordingly, lighting of the environment is not compromised by imprecise mounting of the housing and can be redressed by positioning the reflector as required. The invention also allows the fixture to be moved easily along the support bars connected to the joists even after the bars have been connected.

Abstract: A self locking mounting bar having a notch near one end, which notch fits onto the upper edge of a main runner of a suspended ceiling. The other end of the bar slides into one end of a lighting fixture frame. The bars are generally used in pairs to provide an adjustable mounting apparatus for recessed lighting fixtures; a pair of bars mounted at the same end of the fixture frame, but on opposite sides thereof, may slide toward or away from each other to accomodate variable ceiling runner spacings. Preferably, two pairs of self locking adjustable mounting bars are used to mount a fixture, one pair at each end of the fixture frame. The bar is mounted by placing the notched portion of the bar onto the upper edge of a ceiling runner. The bar then may be locked in place by bending a tab at the end thereof underneath the upper edge of the runner.

Abstract: An adjustable mounting frame, and a kit including this frame, for mounting recessed lighting fixtures, and a method therefor. The mounting frame includes a mounting ring and spring members which can hold a lighting fixture trim in place. In addition to the mounting frame, the kit may also include fastening means for mounting the frame onto the ceiling, a junction box, an electrical conduit and/or a socket cup. The mounting method generally involves the steps of installing the mounting frame in the ceiling, and mounting the trim in the frame by inserting the trim into the spring members.

Abstract: A recessed incandescent ceiling light fixture is provided with a heat sensing device for interrupting current flow to an incandescent bulb mounted in the fixture. The top wall of the fixture is encompassed within a cover member which is spaced from the top wall, the cover member including a depending skirt which outwardly laps the sidewalls of the fixture and defines a circumferential slot between the fixture walls and cover member. A heat sensor is mounted on the surface of the cover member in the area between the top wall of the housing and cover member. The cover member is mounted to the housing at spaced points whereby heat transfer from the housing to the cover member is minimized.

Abstract: The present invention is directed to a fixture which is characterized by its ability readily to be lamped and relamped, notwithstanding the fixture is located at a position which is accessible only with difficulty. The fixture includes a socket which coacts with the terminals of a bulb of particular design to center the terminals and to enable electrical and mechanical contact to be effected by a simple inward movement of the bulb relative to the socket.

Abstract: The present invention relates to an attachment clamp adapted to be mounted to a ceiling, such as a dry wall or acoustical tile ceiling, for structurally supporting a lighting fixture to the ceiling. The attachment clamp, which is formed of an integral resilient metal blank and a threaded adjustment member includes a foot portion adapted to be braced against the upper surface of the ceiling and a locking finger adapted to underlie the ceiling in spaced parallel relation to the foot portion, the threaded adjustment member being operable variably to space the foot and finger to clamp a thickness of ceiling between the two noted components.

Abstract: The present invention is directed to a light track device of the type which mechanically and electrically supports fixtures such as spotlights or the like at any selected position along the length thereof, the device being characterized by an improved attachment module facilitating the formation of electrical connections between the conduits in the light track and the mains conduits. The module incorporates clamps or connector fixtures within which the mains conduits may be placed, secure mechanical and electrical interlock between the mains conduits and the fixtures being effected by the exertion of a lateral force against the mains conduits.
