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.
