Abstract
An improved fluorescent troffer lighting fixture particularly intended for recessed mounting to a suspended ceiling grid, the fixture of the invention having a housing frame configured with spaced end plates which secure to a top plate and side flanges without the need for separate fasteners. The end plates, top plate and side flanges of the fixture housing snap-fit together through the use of cooperating fastening elements formed integrally with said end plates inter alia. The fixture housing mounts a louver and a channel with fastening structure integrally formed with the fixture housing, the channel mounting at least one fluorescent lamp and having reflective surfaces opposing said lamp for increasing efficiency of the fixture.
