  • Patent number: 9010972
    Abstract: An organic light emitting display device is disclosed which includes a magnet inserted into a bottom cover. The magnet is used to combine an organic light emitting display panel with a support means which is used to support the organic light emitting display panel and includes an upper cover, the bottom cover and a side cover. A sealing member included in the organic light emitting display panel is fastened to the bottom cover by a magnetic force of the magnet. As such, it is easy to separate the organic light emitting display panel and the support means from each other when a fault is generated in any component. In accordance therewith, the manufacturing process can be simplified and the faulty component can be easily replaced with a normal component. As a result, the manufacturing costs of the organic light emitting display device can be reduced.

  • Patent number: 9010959
    Abstract: A system and method for generating artificial light for interior or exterior illumination are provided to illuminate interior and exterior underground, underwater, ground level, and above ground structures and spaces by employing various combinations of solar photovoltaic-generated power and conventional power to directly power LED or other light sources to provide interior or exterior illumination of a desired optimal intensity. One embodiment of this system provides a virtual skylight that illuminates interior structures and spaces with the benefits of illumination provided by a conventional skylight but without the disadvantages. A direct connection between a solar photovoltaic cell and the LED or other light-producing source eliminates complex and costly circuitry in both interior and exterior applications. The system is configured to provide, alternatively, solar PV power and/or conventional power as required to maintain artificial illumination at a desired optimum threshold intensify.

  • Patent number: 8992038
    Abstract: An illumination system is housed in a footwear, the footwear including a sole and an upper. A structure and a liner form inner layers connected to the upper. A plurality of illumination sources are electrically connected to a power source and positioned adjacent to the liner. The illumination sources are positioned between the liner and upper. A batting is designed to be light diffusing, while the upper has a light diffusing section. The light emitted from the plurality of illumination sources is diffused as it passes through the batting and light diffusing section. Aesthetic designs can be creating, either through the arrangement of the plurality of illumination sources or the provision of a light impermeable section on the upper. The light impermeable section, in combination with the light diffusion section, can be used to form or outline an aesthetic design. The result is an internally illuminated footwear with diffused light.

This allows the cable to conduct a low voltage feed across the conductive strand, and allows the strength strands cable to mostly support the tension load particularly of a hanging luminaire fixture as well as resisting lateral compressive forces from a cable gripping device.

  • Patent number: 8783919
    Abstract: A lighting apparatus and method of use provides for increasing the visibility of a cyclist. The lighting apparatus includes a plurality of lights that may be arranged in a linear array to facilitate attachment to elongate members of a bicycle. The plurality of lights can be mounted on a substrate that is received in a mounting member, which in turn can be attached to a bicycle. Alternatively, the lighting apparatus may be formed integrally as part of a bicycle. Attachment of one or more lighting apparatuses to a bicycle can provide for increased visibility of a cyclist from the front, the rear, or the side, and may be configured to provide increased visibility when it is either dark or light outside.

  • Patent number: 8783908
    Abstract: A flashlight with light emitting diode (LED) sources that produce at least two different colors and at least two other activatable components. The colored LEDs and activatable components cycle on and off using two or three separate switches. One switch cycles preferably white LEDs on and off. Another switch preferably cycles between a non-white LEDs and two other activatable components and combinations thereof. The activatable components include strobes, sirens, GPS tracking, emergency calling, radio, weather notification, laser light, and light not visible to humans. A third switch disposed on the exterior surface(s) of the body that is operable to asynchronously cycle through the functions of the white light source, wherein the functions include blinking, strobe, pre-programmed varying visible intensity, and Morse code messages.

  • Patent number: 8764219
    Abstract: A light fixture having a ā€œUā€-shaped frame inside a sealed cylindrical housing. Mounted along the center of the face of the frame are one or more LED lamp panels, which include a number of LEDs, some of which may be powered by a back-up source such as an optionally supplied battery for emergency egress lighting. The lamp panels are mounted using a thermal interface material to promote heat transfer from the LED lamp panels to the frame, which in turn radiates the heat into the volume of the housing to enhance cooling. To each side of the LED lamp panels, a highly polished reflector is attached to the frame to focus and concentrate the light while simultaneously shielding the LEDs from heat radiated from the frame. Attached to the obverse side of the frame is a ā€œUā€-shaped back cover that forms an electrical enclosure. An optional diffuser may be supplied.
