Freestanding luminaire having floor-supported frame integrated with light fixture

摘要

A freestanding luminaire includes a floor-supported frame having a base adapted to rest on the floor, an overhead beam arrangement and an upright member connected at its lower end to the base and at its upper end to the beam arrangement so as to support it in a cantilevered fashion over a work surface. The beam arrangement includes a central longitudinally extending beam and a plurality of cross beams attached to the central beam at spaced locations therealong and extending in transverse relationship to the longitudinal extent of the central beam. The central beam is attached at one end to the upper end of the upright member of the frame and extends in transverse relationship outwardly therefrom. The luminaire also includes a plurality of lamps being preferably of the type which use fluorescent tubes, mounted to and extending between the cross beams. Further, the luminaire has a light enclosure formed by a plurality of interconnected wall members which are attached about the central and cross beams to define a housing encompassing the beams and the lamps mounted thereto and having upper and lower openings therein. A pair of lens plates are disposed in the housing across the openings. In such manner, the overhead beams, the lamps and the light enclosure together integrally define a cantilevered light fixture which directs the light produced by the lamps upwardly toward the ceiling and downwardly toward the work surface.
