Abstract: A lighting fixture having a simplified structure is provided with such benefits as a junction box attached directly to the housing, a full reflector for improved optics, and support means for installation in different ceiling structures. A bulb or lamp is disposed in a socket which is attached to the reflector such that the lamp is disposed entirely within the volume of the reflector. Additionally, 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. Accordingly, lighting of the environment is not compromised by imprecise mounting of the housing and can be redressed by positioning the reflector as required. The invention also allows the fixture to be moved easily along the support bars connected to the joists even after the bars have been connected.

Abstract: A self locking mounting bar having a notch near one end, which notch fits onto the upper edge of a main runner of a suspended ceiling. The other end of the bar slides into one end of a lighting fixture frame. The bars are generally used in pairs to provide an adjustable mounting apparatus for recessed lighting fixtures; a pair of bars mounted at the same end of the fixture frame, but on opposite sides thereof, may slide toward or away from each other to accomodate variable ceiling runner spacings. Preferably, two pairs of self locking adjustable mounting bars are used to mount a fixture, one pair at each end of the fixture frame. The bar is mounted by placing the notched portion of the bar onto the upper edge of a ceiling runner. The bar then may be locked in place by bending a tab at the end thereof underneath the upper edge of the runner.

Abstract: An adjustable mounting frame, and a kit including this frame, for mounting recessed lighting fixtures, and a method therefor. The mounting frame includes a mounting ring and spring members which can hold a lighting fixture trim in place. In addition to the mounting frame, the kit may also include fastening means for mounting the frame onto the ceiling, a junction box, an electrical conduit and/or a socket cup. The mounting method generally involves the steps of installing the mounting frame in the ceiling, and mounting the trim in the frame by inserting the trim into the spring members.

Abstract: A recessed incandescent ceiling light fixture is provided with a heat sensing device for interrupting current flow to an incandescent bulb mounted in the fixture. The top wall of the fixture is encompassed within a cover member which is spaced from the top wall, the cover member including a depending skirt which outwardly laps the sidewalls of the fixture and defines a circumferential slot between the fixture walls and cover member. A heat sensor is mounted on the surface of the cover member in the area between the top wall of the housing and cover member. The cover member is mounted to the housing at spaced points whereby heat transfer from the housing to the cover member is minimized.

Abstract: A connector mechanism for linking the ends of successive fluorescent fixtures includes a pair of plates defining the ends of the fixtures, one said plate including a projecting hook portion which extends through the other said plate. The hook poriton includes a cam surface inclined toward the first plate, the second plate including a slide having a locking shoulder positioned to engage the cam surface. A threaded connection to the slide enables the slide to be drawn along the cam surface and accordingly to clamp the end plates tightly against each other.

Abstract: An aligning and joining mechanism for coupling and forcing the abutting ends of fluorescent luminaires into intimate engagement comprises a spanning member extending from one luminaire slidably into a receiver on the other luminaire. The spanner member includes a cam surface disposed adjacent a threaded component on the receiver. When the threaded component is driven against the cam portion, the inclination of the cam causes the abutting ends of the luminaires to be tightly compressed one against the other.
