Abstract: This invention provides a vapor-tight luminaire with a housing that defines a continuous and unbroken sealed tubular lens extending in a longitudinal direction. The housing includes a pair of end cap structures removably and sealably mounted on each of opposing respective housing ends. The housing removably supports a lamp assembly that can include various reflector arrangements. The lamp assembly can include fluorescent tubular lamps and can include electronics, such as a ballast circuit. Illustratively, a supporting rail suspended from each of the opposing housing ends by respective posts slidably supports the lamp assembly. In this manner each of the housing and the lamp assembly are constructed and arranged to allow the lamp assembly to be passed into and out of the housing along the supporting rail when at least one of the end cap structures is removed from the respective one of the housing ends.

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.
