Abstract: The housing for a light fixture includes a plaster frame with an opening. The can light, having opened ends along the top and bottom, is positioned through the opening. A trim assembly and lamp assembly are connected to the bottom side of the can. An outer housing, having dimensions suitable for placing the housing between joists having sixteen inch centers, is connect to the plaster frame and about the top portion of the can. The outer housing includes a doubler panel positioned within the inner walls of the outer housing and having a geometry and size to match with and fit snugly into the upper portion of the outer housing. The open can allows for convection to draw the heat away from the lamp assembly and into the outer housing. The doubler panel evenly distributes the heat along the exterior surfaces of the housing.

Abstract: Preventing air leakage in a recessed lighting fixture. A plaster frame extends between hanger bars fastened to ceiling supports or joists. The plaster frame includes an aperture sized to receive a can. The can includes a pair of slots. A pair of retention springs are coupled to the plaster frame, on opposite sides of the aperture. Each retention spring is associated with one of the slots of the can. Each retention spring includes a base member and an elongated engaging member extending from an end of the base member. The elongated engaging member has a surface that has a contour corresponding to an outer profile of the can, proximate the slot. For example, a radius of curvature of the surface can correspond to a radius of curvature of the can. Thus, the retention springs engage the can in a substantially air-tight manner.
