ABSTRACT:
FIELD OF THE INVENTION
This invention relates to an outdoor luminaire, in particular an outdoor luminaire having a housing adaptable to a plurality of interchangeable tops and a plurality of interchangeable light transmissive doors.
BACKGROUND OF THE INVENTION
Architects prefer to have the ability to ‘mix and match’ elements when designing so that the selection available is maximized and the lighting scheme can be coordinated throughout the structure and/or surrounding area. It is therefore desirable to have an interchangeable outdoor luminaire having a plurality of interchangeable tops and a plurality of interchangeable light transmissive doors.
SUMMARY OF THE INVENTION
An interchangeable outdoor luminaire includes a housing that has an open top and an open bottom to form a circular top rim and a circular bottom rim, respectively, a plurality of interchangeable tops each with an open top that forms a circular rim that matches the top rim of the housing, and a plurality of interchangeable light transmissive doors each with an open bottom that forms a circular rim that matches the bottom rim of the housing. The circular top rim of the housing has a stepped top edge. The circular bottom rim forms a circumferential recess with a stepped bottom edge. Each of the tops have the same circular rim with an annular flange having the same diameter. The annular flange of the tops has a slightly larger diameter than the circular top rim of the housing. The flange fits over the circular top rim of the housing to form an interface between the housing and the top.
The plurality of interchangeable light transmissive doors are each capable of being received into the circumferential recess of the bottom of the housing and each have the same circular rim with a circular outer edge. The circular outer edge of the door is spaced close to the bottom stepped edge of the housing to provide two closely spaced surfaces that facilitate joining the housing and the door. The circular outer edge has a slightly smaller diameter than the stepped bottom edge, thereby enabling the transmissive door to fit into the circumferential recess.
The plurality of interchangeable tops include a pyramidal top, a dome top, an up-light dome top with a decorative cast guard, and an up-light dome top. The plurality of interchangeable transmissive doors include a flat tempered glass, a round drop glass, a flat drop glass, and a tear drop acrylic. Any of the tops for the housing can be used with in conjunction with any of the light transmissive doors.
