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. The outer surfaces of the optical assembly and removable door have the characteristic of shutting water and accumulated contaminants without leaving residue thereon so as to provide easy cleanability. The optical assembly further incorporates specially designed inner and external optics necessary to compensate for the reduced uplight which is dictated by the three-dimensional design of the optical assembly.
