  • Patent number: 8360599
    Abstract: A LED-based replacement light for a fluorescent socket is constructed such that an entirety of a radially outer portion of a tubular housing at least partially defined by a high-dielectric light transmitting portion is formed of a high-dielectric material. Forming a radially outer portion of the tubular housing of a high-dielectric material prevents a person handling the light from being shocked as a result of capacitive coupling occurring when the LED-based replacement light is installed one end at a time. A circuit board is in thermally conductive relation with the tubular housing, allowing for conduction of heat generated by the LEDs from a side of circuit board opposite the LEDs to the tubular housing for dissipation to the ambient environment.

    Abstract: A lighting source comprises a plurality of LED tubular lighting fixtures having upper and lower ends. Upper and lower mounting caps positioned at the ends of the fixtures have cups for receipt of the fixture ends that locate the fixtures within the caps in a pattern and allow for rotation of the fixtures within the cups. A locking bar extends between the mounting caps, for sealing the ends of the fixtures within the cups against the mounting caps and prevents further rotation of the fixtures. A circuit board located on the upper mounting cap is connected electrically to the LED fixtures. Wires extending from the upper ends of the tubular fixtures pass through apertures in the cups of the upper mounting caps to push connectors on the circuit board for connection to an external DC power source.

  • Patent number: 8201965
    Abstract: A modular light fixture having a construction that enables the same fixture to be used for standard on/off operation under control of a wall-mounted switch in a circuit by itself and/or with other fixtures and to be upgraded in “plug and play” fashion to operate independently of other fixtures in the same circuit and/or for stepped dimming. The modular construction of the fixture also allows for safety and ease of maintenance in that ballasts can be replaced without quickly and conveniently without exposing an electrician or maintenance worker to the internal wires of the fixture. The construction of the fixture also provides temperature management by isolating the temperature-sensitive components of the fixture from high temperatures while placing the lamps of the fixture in an enclosure, or shroud, in which temperature is contained so that the lamps operate efficiently.

  • Publication number: 20120140461
    Abstract: A troffer-style fixture. The fixture is particularly well-suited for use with solid state light sources. The troffer comprises a light engine unit surrounded by a reflective pan. An elongated heat sink comprises a mount surface for light sources. An elongated lens is mounted on or above the heat sink. The mount surface is designed to accommodate the light emitters which may come on prefabricated a light strip. One or more reflectors extend out away from the heat sink on the mount surface side. A lens plate is mounted to proximate to the heat sink and extends out to the edge of the reflector(s). An interior cavity is at least partially defined by the reflector(s), the lens plates, and the heat sink. One or more light sources disposed along the heat sink mount surface emit light into the interior cavity where it can be mixed and/or shaped before it is emitted.
