Abstract: An emergency lighting system comprises a wall unit housing that may readily be located and secured between wall studs in a conventional structure. The housing includes a rotatable door to which an emergency lamp is secured, said door being in a closed position when main electrical power is on such that the lamp is hidden within the housing. The rotatable door is coupled to a motor that is supplied battery power when main electrical power loss is detected, thereby rotating the door to an open position and exposing the emergency lamps. The emergency lamps are also illuminated by battery power.

Abstract: A T-bar mounting bracket assembly for a luminaire fixture frame having a bracket, a clip vertically adjustable relative to the bracket, the clip extending through an opening in the bracket, a fastener extending through the bracket and the clip and, the fastener spaced from a location where the clip passes through the opening.

Abstract: A luminaire system having an elongated throughway utilizing a thermal chimney effect. The thermal chimney effect within the throughway circulates air to remove heat generated from the electrical components of the system. Dissipating heat into the throughway from the electrical components can increase the life expectancy of the lamp and the output of the lamp. The electrical components of the system being entirely sealed and isolated from the throughway results in a permanent air, dust, and water tight seal. The seal can minimize damage to the electrical components of the system as well as prevent the build up of moisture and dust within these sealed components.

Abstract: The invention comprises a completely recessed wall-wash lighting fixture capable of being installed within a ceiling. The lighting fixture comprises a housing, which contains a lamp. The invention may comprise a lighting fixture further comprises a reflector disposed within the housing and adjacent to the first end of the housing. The invention may also comprise a flared lamp shield attached to the housing, which is capable of protecting the lighting fixture from damage. The lamp shield extends below the ceiling when the lighting fixture is installed.

Abstract: A luminaire and mounting bracket combination is disclosed which allows the luminaire to be readily installed and retained by the bracket while the installer permanently affixes the luminaire directly to the bracket. Single installer capability is therefore allowed due to the construction of the support bracket and luminaire combination described. The bracket incorporates the use of a plurality of support arms and possibly a lower support bracket which correspondingly fit into apertures formed in the luminaire support frame formed on the mounting face of the luminaire. The design allows the luminaire to be vertically lowered on the support bracket and retained thereby while the installer fastens the luminaire directly to the bracket without need for additional support mechanism or aid.

Abstract: The present invention provides a luminaire comprising a lamp housing having an upper surface and at least one opposed pair of lamp holders extending downwardly from opposing ends of said housing. The housing includes a plurality of apertures in the upper surface thereof to permit transmission of light therethrough and a reversible reflector capable of being secured to said housing in a plurality of positions having a plurality of apertures therein wherein in a first position the apertures in said reflector are aligned with the apertures in said housing to permit light transmission therethrough and wherein in a second position the apertures in said housing are covered by said reflector to prohibit light transmission therethrough.

Abstract: The present invention is an adjustable hanger bar assembly for a light fixture. The assembly maintains structural integrity between first and second bars to support a recessed light fixture while being extended to distances where typical mounting assemblies fail. The hanger bar assembly comprises first and second bars which slidably engage one another. One of the first and second bars comprises a foldable foot which may be extended to increase the length of the hanger bar assembly.

Abstract: An recessed luminaire trim assembly, comprises an outer trim, an inner reflector portion having a polygon shaped cross-section defined by a plurality of reflectors and a plurality of seams defined between each of the plurality of reflectors, a flange extending outwardly from a peripheral edge of the inner reflector, a spring connected to the outer trim, the spring having at least one leg engaging the inner reflector portion and tightening the plurality of seams.

Abstract: A gasket for a vandal resistant luminaire, the gasket is constructed to be disposed between an electrical component housing and a lens wherein the lens is held to the electrical component housing with a front trim ring surrounding an outer portion thereof. The gasket is designed to form a seal between the lens and electrical component housing and absorb physical shock placed on the lens and/or the electrical component housing.

Abstract: A recessed light fixture having a rotation ring allowing rotation of a lamp mounted over the fixture frame aperture, the rotation ring easily rotatable on the frame and held in place by a ring clamp. The recessed light fixture rotation ring has a mechanical brake for locking the ring in place after positioning of the lamp. The ring also has a slip disc positioned between the surface of the frame and the ring to allow easy rotation. The housing of the fixture has junction boxes mounted on side walls which are hinged to the sidewalls of the housing and which swivel into the interior of the housing for ready access after installation through the aperture of the frame. The lamp of the fixture movable about a horizontal adjustment and vertical adjustment axis while also maintaining position with respect to the reflector.

Abstract: A luminaire comprised generally of a mounting plate including a plurality of mounting blocks secured to the mounting plate; and a plurality of LEDs, wherein at least one of the LEDs is positioned upon each of the mounting blocks. The mounting blocks include face portions and may be arranged in a plurality of configurations on the mounting plate.

Abstract: A zoomable light beam spreader comprising first and second multiple-lens arrays includes a plurality of plano-convex lenses in correspondence with a plurality of plano-concave lenses having matched, curved optical surfaces. In a zero-power state, the two multiple-lens arrays are very closely spaced so that the matched convex and concave surfaces effectively cancel each other optically but, as the two arrays are separated coaxially along the axis of a light beam, beam divergence angle increases as a function of the distance of separation. A large amount of beam divergence is obtained when the curved surfaces of the plano-concave lenses of the second array are positioned beyond the focus points of the plano-convex lenses of the first array.
