Abstract

A luminaire having a frame that includes opposite first and second ends with a connecting member extending therebetween. The frame has an opening remote from the connecting member. First and second lamps are supported by the frame adjacent the first and second ends, respectively. A main reflector extends between the first and second ends of the frame and has a reflecting surface directed towards the opening of the frame. First and second reflecting members are disposed adjacent the first and second ends, respectively, of the frame and between the first and second lamps, respectively, and the opening of the frame. Each of the first and second reflecting members includes first and second curved reflectors and a plurality of baffles extending between the first and second curved reflectors. The first and second reflecting members direct light from the first and second lamps, respectively, through the opening in the frame.

Claims (26)

1. A luminaire, comprising:
a frame including opposite first and second ends with a connecting member extending therebetween, said frame having an opening remote from said connecting member;
