Abstract
An integrated suspension ceiling and recessed lighting fixture system is disclosed in which a fixture is supported primarily on arched bridging members which extend between parallel runs of the grid of the suspension ceiling. The bridging members lock at their ends in the runs and maintain a predetermined spacing between the runs thus permitting relatively long uninterrupted fixtures to be installed in the suspension ceiling. The bridging members also support a continuous channel or raceway which permits the fixture to be wired as a unit regardless of its total length. A reflector is supported by flanges of the inverted tees constituting the runs along the sides of the fixture so separate framing is not required. With the invention recessed lighting fixtures of substantially any desired length may be installed in a suspension ceiling system.
