  • Patent number: 8220957
    Abstract: Retrofit systems for replacing the outdated components of an existing light fixture. The retrofit systems may utilize the previously installed housing of the existing light fixture. The retrofit systems include brackets that are positioned on the ends of the housing. The positioning of the brackets is based off of the ceiling, t-grid, or the bottom of the housing. Lamp sockets with associated lamps, an optional ballast tray with associated ballast, reflector(s), lamps, and a shielding mechanism are all mounted on, and their position in the housing dictated by, the mounting brackets. Thus, regardless of the depth of the housing, the lamps are positioned a uniform distance from the ceiling opening to create consistent light distribution. Moreover, because these components are not directly attached to the housing, their dimensions need not precisely match those of the housing. Rather, the retrofit system can be installed in housings of varying sizes and shapes.

    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.

  • Patent number: 7887216
    Abstract: A lighting system comprises a row of light emitting diodes (“LEDs”) receiving electricity and producing light and heat. The row of LEDs can be located in a channel or a groove of a piece of material, such as an aluminum extrusion or a bent piece of metal. The channel can have an optically reflective lining, for example, providing either diffuse or specular reflection. Accordingly, the channel can reflect light emitted by the LEDs. The piece of material can also include a heat sink for transferring heat from the LEDs to air via convection or air flow. The heat sink can comprise fins or protrusions that facilitate convection.

  • Patent number: 7862202
    Abstract: A method and apparatus for motion sensor installation includes an apparatus for installing a lighting accessory to a first luminaire having a luminaire housing. The bracket includes a coupling member operative to couple the bracket to one of the luminaire housings. A support member extends from the coupling member, and is operative to support the lighting accessory a first distance from the luminaire housing. An attachment member that is operative to attach the lighting accessory to the lighting accessory extends from the support member. The bracket couples the lighting accessory to the luminaire housing without extending the length of the luminaire or creating a substantial gap between two luminaires in a linear configuration. In one aspect, the lighting accessory can be a motion sensor that is operative to control the power to one or more of the luminaires.

    Abstract: A discharge tube 17 of the present invention includes a glass tube 30, a ferrule 40 attached to an end of the glass tube 30, and lead wires 32a and 32b provided at an end of the glass tube 30. The lead wires 32a and 32b are bent and inserted in the ferrule 40 such that they are in contact with the ferrule 40. They can receive external power supply via the ferrule 40. The lead wires 32a and 32b that are non-light-emitting portions of the discharge tube 17 are bent and thus the apparent lengths of the lead wires 32a and 32b can be reduced. The light emitting area of the discharge tube 17 with respect to the whole length is increased.

  • Patent number: 7819548
    Abstract: A safety sleeve apparatus comprises a safety sleeve encapsulating a fluorescent tube for protecting the fluorescent tube from physical damage and for preventing the tube from sliding out of the sleeve and breaking if the sleeve is tilted from the horizontal during installation of the tube into a pair of lamp sockets. The sleeve protects the tube from damage if the sleeve is struck by a hard object, and creates an airspace around the tube to protect the tube from cold and prevent the escape of fragments from a broken tube. The sleeve has a greater inside diameter than the outside diameter of the tube. An end cap is mounted on each end of the sleeve, and the end cap includes a cylindrical ring extending upright from the edges of a flat end wall. Projections are included in the cylindrical ring and the projections attach to the slots in the ends of the sleeve.
