Abstract: The invention generally comprises a compact luminaire enclosure that preferably contains about 14 to 18 cubic inches of air volume and can be used safely with a 50 watt luminaire. The luminaire enclosure comprises a housing and a shroud that is removably attached to the housing. The shroud has a non-planar face that prevents the shroud from laying flat and trapping heat if the enclosure is placed on or falls on a flat surface. The housing can comprise polyetherimide, which has very good heat dissipation properties. The shroud may also comprise polyetherimide. The compact luminaire enclosure of the invention further comprises an internal thermal lamp shield recessed within the housing. The internal thermal lamp shield comprises highly specular material so that it is able to reflect much of the heat coming from an enclosed luminaire. In one embodiment of the invention, the luminaire comprises anodized aluminum.

Abstract: A micro porous gas breather/filter assembly can be coupled to a housing of an electrical enclosure. The filter assembly has a two portion housing with the filter disposed between them. An adhesive on the filter attaches the filter to one or both portions of the housing. The filter allows gas to pass from the enclosure through the filter and to the atmosphere, but prohibits liquid from passing into the enclosure device. By filtering gases and liquids in this manner, the filter vents explosive and/or flammable gases from an electrical enclosure, while preventing liquid and other contaminants from entering the enclosure and damaging the electrical device or its wiring.

Abstract: An optical housing is formed from a blank and a reflector mounting plate. The blank is scored to allow it to be folded into a box with a base and four walls. The box has a circular hole in the base and two wall tabs at the end of each of the four walls. The reflector mounting plate has wall tab slots that receive the wall tabs from the four walls and couples the two parts of the housing together. A set of reflectors is mounted to the reflector mounting plate in a predetermined reflector pattern. Another set of reflectors is mounted to the base of the box in a circular pattern. A third reflector fits into the circular hole in the base of the box and is mounted to the base. A light source is attached to the base of the box and extends vertically through a hole in the third reflector and partially beyond the first set of reflectors.

Abstract: A lighting fixture for lighting a large area such as a sporting field. The lighting fixture has a bowl-shaped reflector with an internal glare and spill control assembly for aiming and controlling the light emitted therefrom. The glare and spill control assembly is located within the bowl-shaped reflector and behind the lens cover of the lighting fixture so that the glare and spill control assembly is substantially isolated from the effects of weather. The glare and spill control assembly preferably has a plurality of arc-shaped louvers located substantially in the upper half of the reflector for controlling glare and spill of the light from the lamp. The lower half of the reflector preferably has either a reflector insert for redirecting light more parallel to the central aiming axis, or a light absorbing baffle for reducing glare.

Abstract: A light fixture is disclosed for lighting a large area such as sporting fields. The lighting fixture has a bowl-shaped reflector with a central aiming axis and a side-mounted lamp mounting socket for a transversely supporting a single-ended lamp with the reflector. The light fixture also has a mounting arm for coupling the reflector to a support member and for supporting the lamp substantially perpendicular to the central aiming axis of the reflector. More specifically, the mounting arm has a first end coupled to the exterior of the reflector and a second end located substantially adjacent the central aiming axis of the reflector. The mounting arm also has a wiring channel extending between its first and second ends and a socket recess located at its first end for mounting the lamp mounting socket therein.

Abstract: A lighting fixture with a lamp end support is disclosed for supporting the free end of a transversely mounted, single-ended lamp. The lighting fixture preferably has a bowl-shaped reflector with a side mounted lamp mounting socket, which supports the base end of the single-ended lamp substantially perpendicular to the central aiming axis of the lighting fixture. The free end of the lamp is supported by the lamp end support, which is fixedly coupled to the interior surface of reflector. The lamp end support has a wire clip member for engaging and supporting the free end of the single-ended lamp and an angled bracket for securing the wire clip member to the interior surface of the reflector.

Abstract: A recessed lighting fixture or downlight is disclosed for mounting in a wide range of sloped ceilings. The recessed lighting fixture has a lamp adjustably coupled to a housing via an adjustable socket assembly having three degrees of movement for aiming the lamp in a particular direction, preferably perpendicular to the floor. The adjustable socket assembly has an upstanding bracket and a socket strap for aiming the lamp. In particular, the upstanding bracket has one end pivotally coupled to the trim collar of the housing for rotational movement of the lamp about a first pivot axis, and its other end pivotally coupled to the socket strap for rotational movement of the lamp about a second pivot axis. Also, the bracket and socket strap are coupled for linear movement of the lamp relative to the housing. In a preferred embodiment, the lighting fixture is provided with a reflector having baffles such that the lighting fixture has substantially the same appearance regardless of the slope of the ceiling.

Abstract: An electric lighting support assembly includes an elongated hollow tubular arm having a plurality of circumferentially and axially spaced wall portions, an electric light supported on the arm, wiring connected to the electric light and running through the arm, an entry aperture for receiving an electric power supply line into the arm at a first of the wall portions, an access opening for gaining access to an electrical connection between the electric power supply line and the wiring in the tubular arm at a second of the wall portions spaced from the first wall portion, and a cover removably attached to the arm at the second wall portion thereof so as to overlie and close the access opening in the arm such that the cover can be removed and reattached without affecting the electrical connection between the electric power supply line and the wiring. The tubular arm has opposing top and bottom sides and opposing lateral sides.

Abstract: A pole top cover assembly includes a generally flat cover plate adapted to overlie an open top end of a tubular hollow pole, an elongated arcuate-shaped bracket formed of yieldably resilient, semi-rigid, semi-flexible deformable material and being disposable along one side of the cover plate, and an elongated fastener rotatably mounted through both an aperture in the cover plate and a hole in the bracket and having external threads threadably engaged with portions of the plate and bracket which form the respective aperture and hole thereof. Rotation of the fastener in one direction relative to the cover plate and bracket causes the arcuate-shaped bracket to engage the plate and to deform and draw toward the one side of the cover plate and thereby expand in length and forcibly engage at opposite ends with portions of an interior surface of the hollow tubular pole so as to retain the cover plate on the pole top end.
