Abstract: A lighting assembly configured to provide a cove lighting effect includes a housing configured to releasably couple a light apparatus comprising a light source coupled to a heat sink. The housing comprises an apparatus portion configured to accommodate the light apparatus, and a wireway configured to accommodate supply wiring for the light apparatus. The housing further includes a trough configured for mounting the housing and for coupling a first housing to a second housing. A light apparatus can include a releasably coupled lens. A light apparatus can releasably engage the housing, and can be removed from the housing when a light source is replaced. A housing front plate can conceal a housing back plate so that only the front plate need be embedded at a wall.

Abstract: A plaster collar assembly having a first ring, a second ring secured to the first ring, and a mechanism arranged at an outer periphery of at least one of the rings for axially displacing the first and second rings during rotation of the secured rings relative to each other.

Abstract: An adjustable recessed light fixture comprises a lamp positionable in orientations wherein the light beam is inclined obliquely relative to a vertical axis, and wherein the inclined light beam can be rotated about the vertical axis. A movable stop is provided which enables the lamp to be rotated in a complete 360.degree. range of rotation. A housing which covers the light fixture includes a removable top wall which provides an effective thermal insulation for the housing. A trim ring is installable such that torsion springs of the trim ring are effectively held within a rotatable spin disc of the light fixture. The lamp can be rotated about a horizontal axis in a manner wherein only a minimal portion of a light beam is cut off by a reflector. A bar hanger for hanging a light fixture frame to a ceiling joist includes relatively slidable rails, wherein ends of the rails can be broken off to shorten the bar hanger without having to disconnect the rails from one another.

Abstract: A lamp assembly for a recessed ceiling fixture includes a support, a lens retainer removably mounted to the support and carrying a lens, a heat shield removably mounted on the lens retainer above the lens, an electric socket supported by an upper end of the heat shield, and a lamp disposed within and supported by the heat shield and electrically coupled to the socket. The lamp includes a reflecting surface that reflects visible light forwardly and transmits heat rearwardly toward a dome shaped reflector surface of the heat shield which reflects that heat forwardly. The heat shield, lamp, and socket can be removed as a unit from the lens retainer in order to be able to replace the lamp while leaving the lens in place. When re-mounting the unit, the lamp engages centering surfaces carried by the lens retainer to center the lamp relative to the lens.
