Abstract: A luminaire assembly which is adapted for easy cleanability. The luminaire assembly includes a housing portion having a substantially smooth outer surface and which is further adapted to receive and enclose a ballast assembly. An optical assembly is further adapted to be affixed to the housing portion in a substantially sealed, water-tight relationship to define an internal chamber to receive and enclose a lamp. The optical assembly has an inner surface and an outer surface contiguous with the housing portion outer surface and has an opening defined therein. A removable door has an inner surface and an outer surface adapted to be affixed in a sealed relationship with the optical assembly opening when in a closed position. The door is further provided with a breathing aperture of a predetermined lateral dimension for permitting ambient air to enter and leave the internal chamber.

Abstract: An apparatus for allowing pivotal movement between a reflector of a lighting fixture and a refractor which extends across an opening in the reflector is disclosed. The apparatus comprises a body portion, a leg portion attached to the body portion, and a retention portion attached to the body portion. The leg portion includes a pair of legs spaced apart from each other, which are closable against an inner surface of the reflector to secure the apparatus to the reflector. The retention portion includes a pair of retainers, each of which is closable around a bolt of the refractor to retain the bolt and allow pivotal movement of the refractor with respect to the reflector.
