  • Patent number: 9677722
    Abstract: Lighting assembly comprises an optical fiber light guide panel member having a light conducting core cladded on opposite sides by cladding made of optically transparent material having a lower index of refraction than the light conducting core to cause total internal reflection of conducted light within the light conducting core at the core-cladding interface. Disruptions at one or more areas of the cladding cause conducted light within the light conducting core to be emitted from one or more areas of the panel member. Electrical circuitry is bonded to one or both sides of the cladding. One or more LEDs embedded in the panel member are in electrical conduct with the electrical circuitry and optically coupled to the light conducting core.

  • Publication number: 20140022812
    Abstract: A display front lighting device comprises an optically transmissive sheet member that provides reflective means to evenly distribute light for the illumination of the text and/or graphics of display modules while permitting the text and/or graphics to visibly pass through the sheet member for viewing. The transmissive sheet member has LEDs offset mounted at an angle relative to one side of the sheet member such that a portion of the light emitted by the LEDs is reflected by the one side onto the adjacent dis play. The LEDs are mounted on a flexible printed circuit board, or alternatively on the conductive traces bonded to the sheet member.
