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.
