  • Patent number: 8915001
    Abstract: The invention relates to a decorative element (10) for a motor vehicle and to a method for producing the same. The decorative element (10) thereby comprises an at least partially transparent decorative film (12) applied to a flat carrier element (30) and back injection molded with two plastic layers (14, 16). At least the first plastic layer (14) is thereby at least partially transparent. The use of the first plastic layer (14) as an optical conductor is thereby made possible, allowing particularly optically attractive light coupling into the decorative element, and opening particularly extensive latitude in design.

  • Patent number: 8884786
    Abstract: The invention relates to a light sign (10) for displaying an instruction and/or guidance for ground airplane traffic at an airport, comprising a casing (20) with a transparent display panel (21) for representing an instruction and/or guidance symbol (Z), and a light source arranged inside the casing (20) with at least one luminescent diode (32) for illuminating the display panel (21). A diffusion panel (22) is made for scattering and/or back-scattering incident light, wherein the light source is arranged between the display panel and the diffusion panel. The at least one luminescent diode (32) is aligned on the diffusion panel (22) so that the display panel (21) is not illuminated directly, but indirectly by back-scattering of the light emitted from the at least one luminescent diode by the diffusion panel (22).

  • Patent number: 8878666
    Abstract: An emergency exit sign having a beacon module for indoor positioning and an indoor positioning system using the same are provided. The emergency exit sign includes a power supply unit, an AC/DC converter, an indoor positioning beacon module, an LED lamp, and a charger. The power supply unit receives an input of a power source and supplies the power source. The AC/DC converter converts the power source supplied and supplies a driving power source. The indoor positioning beacon module periodically wireless transmits a beacon signal including a beacon ID through a built-in antenna. The LED lamp is installed within the housing such that the lamp is positioned in rear of the display. When a power source is not supplied from the power supply unit, the charger supplies a driving power source.

  • Patent number: 8832979
    Abstract: The present invention discloses a backlight module and an LCD having a positioning structure for fixing an optical film and a frame. The frame includes a side frame having an assembling hole. The optical film is placed on the side frame and includes a protruded ear having a positioning hole. The positioning structure includes: a magnetic member installed inside the assembling hole; an attracted member including a compression part and a positioning pillar, wherein the positioning pillar is connected to the compression part and gets inside the assembling hole through the positioning hole such that the positioning pillar is connected to an attraction hole due to a magnetic effect to make the compression part compress and fix the optical film on the side frame. The positioning structure can fix the optical film in X, Y, and Z directions to raise the positioning reliability, assembling speed, and capacity.

  • Patent number: 8826572
    Abstract: An illuminated sign having a housing unit with a frame and one or more light emitting arrays to provide visible indicia and a backlight module for mounting a transparent backlight panel which is held in close contact with a reflection panel and optically positions a light emitting unit to emit light through the backlight panel for emission from the front of the sign. The replaceable sign member accommodates the display of visible indicia and is backlit by the light emitting unit. A light sensor is mounted on the backlight module for measuring ambient light. The light emitting unit can be driven by a signal from the light sensor to automatically set a contrast level of illumination to optimize the information presented by the illuminated sign.
