This invention relates to an improved lighting fixture of the type which may use a trim-ring connected to the bottom of a lighting fixture housing can and is applicable to lighting fixtures of either the recessed variety or of the track variety. In most of such housings, portions of the sheet metal walls are punched out and deflected inwardly forming lugs, or auxiliary brackets are welded to the inside of the housing, to support such baffles, trim-ring means or other assembly means. Such lugs, or brackets, generally have extremely sharp burr edges. The means used for fastening the trim rings or other means to such lugs generally are well known and are usually either torsion springs or tension springs. In each instance, it is necessary for the installer to insert his hands into the interior of the can to install the secondary retaining spring members and thereby expose his hands to the sharp burrs on the edges of the sheet metal lugs used to support the retaining spring members. The present invention provides an improved trim-ring and baffle mounting system for a simplified assembly and retention system for aesthetic auxiliary items. There is provided an internal support system for the housing of a can-type lighting fixture that is simple in construction and can be assembled rapidly at the point of installation. This can be adjusted axially to a plurality of positions in a simple and effective manner without the use of external fastening means such as screws and without the problem of confronting sharp burr-like edges of sheet metal projecting into the interior of the can-like housing.
