Abstract
A recessed lamp fixture having a minimal plaster frame and a lamp housing. The plaster frame comprising a mounting bracket is adapted to receive a variety of differently sized and shaped lamp housings. The housing comprises an integrated lamp and trim assembly that is retained within the housing by a biased retaining spring. The housing is designed with minimal openings for reduced heat loss and air flow. The frame further comprises an integrated junction box and hanger bar system adapted to mount the fixture behind a panel. The junction box and the lamp housing also comprise an electrical power line retaining means to securely fasten the line to the box and housing. The hanger bar is slideably attached to the frame with ends that are designed to engage ceiling and wall supporting structures without the need for additional fasteners. Another feature of the invention resulting from the design of the frame and housing is a unique method of manufacture, whereby a minimal number of steps is required to assemble the fixture.
