  • Patent number: 6082878
    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.

  • Patent number: 5951151
    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.
