Abstract: This invention provides a vapor-tight luminaire that maintains a moisture-proof, sealed lower housing for the light-producing lamps (fluorescent lights, LED arrays, etc.) while isolating the electronic components in a separate, upper housing that is spaced apart from, and largely thermally isolated from, the lamps. The lamp housing comprises a unitary non-penetrated tubular lens with one or more removable end caps, sealed by gaskets. The lamp assembly is slidably mounted within the lower housing so that it is readily removable and replaceable with another assembly of the same or different type. The electronics in the upper housing is readily accessible and replaceable by removing a top cover that encloses a three sided channel member. The upper housing is metal and desirably enhances heat exchange with the environment. The two housings are held together by a pair of opposing end cap structures that include a housing end and a removable end cap.

Abstract: This invention provides a lighting fixture for use in low-ceiling applications and/or outdoor environments, such as parking garages that allows for the use of more-efficient lighting sources, such as fluorescent lamps, with more-even distribution of light along the sides of the fixture so that the surrounding space is fully and efficiently illuminated. Two elongated light sources are mounted upon opposing sides, and surrounded by a pair of respective side reflectors. The side reflectors direct the light of the two light sources in a generally sideward and somewhat-downward direction. The lower portion of the side reflectors collectively define an overall wide angle and each lower portion completely overlies a respective one of the side light sources mounted above. A third light source can be located centrally, beneath the lower portions to provide downward light, which is further reflected generally downwardly by the wide angled lower portions.

Abstract: This invention provides a high-output industrial light fixture that employs a plurality of commercially available fluorescent light sources in an array of adjustable arm assemblies each housing one or more light sources (fluorescent bulbs) in an associated reflector box or other source housing structure. By adjusting the arm assemblies, a more-precise spread of light onto the target surface can be achieved. Arm mounting brackets can be provided with one or more locking positions to facilitate multi-position angular placement of each individual arm. A plurality of arm assemblies can be provided around a center housing or hub, each directed outwardly in a radial direction from a central point or axis of the center housing/hub. Each arm's source reflector box/source housing structure can be located to project light either downwardly or upwardly and can be angled at a plurality of angular adjustment positions with respect to the center housing in each of the upward and/or downward positions.

Abstract: A bracket system for fluorescent lighting fixtures using tubular bulbs and a ballast assembly for mounting on such brackets is provided. Each of a pair of opposing brackets includes a main bracket section and at least two bulb-mounting/connecting ends that receive tubular fluorescent light bulbs therein and that electrically connect the light bulbs with the ballast-generated, high-frequency driving current. The ballast housing is adapted for quick-connection to and disconnection from the main bracket section. Contact pads are provided to each of the main bracket section and the ballast housing. Conventional AC power is received through some of the contact pads for input to the ballast, and high-frequency driving current is transmitted from the ballast back to other contact pads for distribution to the underlying bracket bulb-mounting/connecting ends and to those of the opposing bracket.

Abstract: A fluorescent fixture having high efficiency and a low profile is provided. The fixture includes a housing having a central well with a pair of tubular fluorescent bulbs mounted therein and extending in a lengthwise direction. Each bulb is surrounded by a double-trough specular reflector with a local peak that extends from the base of the well, toward the bulb. The local peak is positioned generally along a centerline through the bulb. A pair of maximum trough bottoms are positioned on each of opposing sides of the centerline. The reflector configuration reflects a substantial amount of incident light away from the bulb surface and out from the fixture opening where it is needed. The housing includes a pair of sloped outer sides that extend in a widthwise direction away from the reflector outwardly to opposing widthwise edges of the housing to enable light reflected from the reflector to be transmitted toward the widthwise edges of the housing free of obstruction thereto.
