A ceiling frame is provided for a lighting fixture. The ceiling is of the type made of plaster panels commonly known as dry wall, wallboard, plaster board, or gypsum board. A rectangular opening is made in the plaster panels between rafters and the lighting fixture is suitably mounted on the ceiling above the panels. The ceiling frame includes side frame members having vertical flanges positioned adjacent the edges of the ceiling panels at the rectangular opening and horizontal flanges extending outwardly from the opening along the lower surfaces of the panels. The horizontal flanges are affixed to the panels by pop rivets or the like which also extend through upper horizontal flanges or brackets adjacent the upper surfaces of the panels. The ceiling frame also includes two end frame members of similar design but affixed to the ceiling panels adjacent the end edges of the opening by rivets and brackets. When the frame members are in place, joint compound is spread over them and feathered outwardly to the ceiling surface to provide a smooth, rimless frame for the light fixture.
