Patents Assigned to Cordelia Lighting Inc.
  • Publication number: 20130163254
    Abstract: A recessed lighting fixture providing illumination from a light source including a plurality of light emitting diodes (LEDs) wherein the fixture is placed within the ceiling space above a ceiling panel or wall. The fixture has a low aspect ratio heat sink. An interchangeable trim ring has an integrated light reflector and attaches to the bottom of the heat sink via rare earth or super magnets. A flange of the heat sink and a flat annular surface of the trim ring engage each other, providing a large contact surface to enable conductive heat transfer. The flange and flat annular surface are located below the ceiling panel, which is at room temperature to help cool the recessed LED lighting fixture through radiation and air convection.

  • Patent number: 8308322
    Abstract: A recessed ceiling light fixture with spring biased retainer clips that retract flush or are biased away from the side of the can housing for installation is disclosed. The fixture includes a housing having a side wall, a top wall, and an open bottom. Two rigid retainer clips are mounted diametrically opposed on the housing. Each retainer clip has a mounting tab inside the housing extending into a leg that passes out of the housing, which leg is bent to form an elbow, which elbow extends to a strut passing back into the housing, wherein the mounting tab selectively engages the side wall to limit movement of the spring clip. A bolt and coiled spring create compliance and bias in the spring clip by passing loosely through a slotted opening in the top wall at one end and joining the mounting tab at the other end.

  • Publication number: 20120182744
    Abstract: A recessed LED ceiling light fixture kit for installation to a ceiling panel or plaster frame in residential homes or commercial buildings is disclosed. The kit includes an LED engine with at least one LED facing downward, an LED driver, and an annular shaped, finned heat sink that receives the LED driver therein and the LED underneath. The fixture includes a tubular-shaped can having an open bottom and a top engaging the heat sink. Detachable can retainer springs or threaded fasteners engage the can at its circumference, wherein the springs mount the can to the ceiling panel, or alternatively, the fasteners attach the can to the plaster frame. A trim ring is snapped onto the can at its open bottom, and an electrical junction box sits on top of the heat sink.

  • Patent number: 8182116
    Abstract: A recessed lighting fixture providing illumination from a light source including a plurality of light emitting diodes (LEDs) placed within a cavity of a planar surface, such as a ceiling, wall, or shower. The fixture comprises a baffle integrated with a low profile heat sink that is used to draw heat out of the fixture and communicate that heat to a trim ring of the fixture for dissipation of the heat in the room so that higher intensity light sources can be used. Improved grounding of the recessed trim unit to the recessed housing is provided with combination support and grounding springs. One embodiment of the light source is fixed in position while a second embodiment is gimbal mounted for aiming the light produced by the fixture.

  • Patent number: 8177176
    Abstract: A hanger bar for supporting a recessed light fixture is attachable to ceiling joists or a T-bar grid of a drop down ceiling. First and second bars of the hanger bar slide and telescope. First and second spring clips are detachably coupled to the brackets at the ends of the first and second bars, respectively. Each of the first and second clips has a pair of downwardly extending arms bent inwardly toward one another, a first leg extending from a first arm, a second leg extending from a second arm, and an outwardly-extending foot on the second leg. The spring clips snap on to the T-bar grid. Each bracket includes a nail that is angled away from the hanger bar and downward so that the nail head is below the level of the hanger bar. The angled nails enable easy hammer strikes to attach the hanger bar to ceiling joists without accidental hammer blows to the hanger bar. The bracket may be discrete from the hanger bar but attached via tox clinching or a tab pass-through attachment.

  • Patent number: 8138418
    Abstract: A junction box having a sheathed cable retainer structure is disclosed. The junction box contains pry outs that cover openings at corners of the junction box wherein the pry outs are removed and a sheathed cable or like electrical wiring can pass therethrough. A strain relief bracket having segmented distal bends at opposite ends thereof engages the cable and under bias pushes the cable against an indent formed on a wall inside the junction box opposite the cable.
