发明名称 INTEGRATED LIGHTING SYSTEMS FOR SUSPENDED CEILINGS OR THE LIKE
摘要 In an integrated suspension ceiling it is disclosed in which a fluorescent tube type lighting fixture is supported from and directly over a runner forming a part of the grid of the ceiling system. The runner is provided with a central web and oppositely extending flanges extending from the sides of the web. The web is formed with an opening above which the lighting fixture is supported. The lighting fixture includes a ballast frame separately supported on the runner above the opening, a reflector positioned in the opening below the ballast frame supported directly on the rubber and a louver mounted within the opening flush with a plane of the ceiling. Each of the frame, reflector and louver are separately supported and removable from the runner for installation and service. Because the lighting fixture is supported directly on the runner and is removably attached thereto, the lighting fixture can be installed after the grid is installed. The fixture does not provide an interruption in the ceiling system. Therefore, fixtures can be conveniently located where relatively high levels of light intensity are required without requirying excessive lighting in areas where lower lighting levels are acceptable.
