A lighting fixture having a simplified structure is provided with such benefits as a junction box attached either permanently or releasably to the housing, a full reflector for improved optics, and support means for installation in different ceiling structures. The reflector is positionable within the housing, whereby inexact or inaccurate mounting of the housing to the ceiling structure can be corrected by changing the orientation of the reflector. Also provided are novel junction boxes. In various embodiments, the junction box may contain an L-shaped door, to cover an L-shaped opening which allows the interior of the junction box to be inspected from the bottom after installation. Another embodiment of junction box includes side walls flexibly joined to permit installation and removal of the junction box. Preferably, this latter embodiment is installed in a fixture through the bottom opening through which the reflector, socket, bulb, and the like are installed.read more

Patent
Plaster frame for recessed lighting
Abstract: A plaster frame for mounting a lighting fixture in recessed fashion in a ceiling comprises a main body portion including a rectangular, planar member defining an aperture therein, the aperture being similarly dimensioned to the ceiling aperture in which the lighting fixture is to be mounted Hanger bar brackets are integrally formed with the planar member at breakaway junctions along opposite, first sides of the planar member The hanger bar brackets are adapted to receive hanger bars for mounting the plaster frame between spaced joists supporting the ceiling Each hanger bar bracket is removable from the planar member by bending at the breakaway junctions The hanger bar brackets are reattachable to the planar member along opposite, second sides thereof by means of bendable, spaced tabs formed on the brackets receivable in similarly spaced apertures defined in the planar member The ability to relocate the hanger bar brackets permits the plaster frame to be oriented in two ways between the spaced ceiling joists Complete removal of the hanger bar brackets permits insertion of the plaster frame through an aperture defined in an existing ceiling to provide support for a lighting fixture on the interior surface of the ceiling
