  • Patent number: 8083369
    Abstract: An adapter bracket which enables the installation of a door frame or louver into a recessed fixture that sits on a T-bar supported by a ceiling without having to custom design a hinge and latch system to match the original fixture or require the installation of a false frame that lifts the fixture. The brackets slide between the T-bar and the existing fixture. The bracket is also slightly wider than the T-bar opening. The door frame will keep the brackets spaced wide enough to ensure that the assembly would not fall out of the opening. The hinge and latch mechanism for the door frame is built into its end rails and latches onto the bracket to ensure the door frame is supported and held in position.

  • Patent number: 7261436
    Abstract: A method for implementing lighting utilizes a lighting fixture having a plurality of lateral reflector positions, including selectively installing a first type reflector panel or a second type reflector panel in individual ones of the plurality of lateral reflector positions, the first type reflector panel having a greater uplighting capacity compared to the second type reflector panel, whereby the selectively installing determines, for the lighting fixture, a proportion of uplight versus downlight. For a plurality of tube positions disposed in a plane, a method may include vertically positioning a reflector assembly with respect to the plane. Individual reflector panels may be replaced by flexing the panel. A method may include providing a sensor switch operative to detect an occupant and connect an electrical path when the occupant is detected, and providing a selector for selecting ones of the ballasts to be connected to the electrical path by the sensor switch.

  • Patent number: 7207690
    Abstract: A method, for implementing lighting by utilizing a lighting fixture having a plurality of laterally-spaced light source locations and corresponding lateral reflector positions, may include selectively installing a reflector of a first type or a second type in respective ones of the plurality of lateral reflector positions, the first type reflector having greater uplighting capacity compared to the second type reflector, whereby the selectively installing determines a proportion of uplight versus downlight. For a plurality of tube positions disposed in a plane, a method may include vertically positioning a reflector assembly with respect to the plane. Individual reflector panels may be replaced by flexing the panel. A method may include providing a sensor switch operative to detect an occupant and connect an electrical path when the occupant is detected, and providing a selector for selecting ones of the ballasts to be connected to the electrical path by the sensor switch.
