  • Patent number: 6095669
    Abstract: A recessed lighting fixture for installation in a sloped ceiling which defines an opening therein for communicating light from the fixture to a space below the surface of the ceiling, in which a cylindrical housing having a closed end and an open end is secured to a frame at an oblique angle relative to the frame in order to position a lower edge of the housing in a plane defined by the sloped ceiling. Screws extend through slots in the housing, which screws guide the movement of the housing along the slots, whereby the housing is selectively moveable from a first position relative to the frame to a second position to position the lower edge of the housing in the plane of the ceiling in order to accommodate the thickness of the ceiling in which the fixture is installed.
