  • Patent number: 7922374
    Abstract: The present invention provides various lamp assembly configurations for motorized vehicles. In one embodiment, the lamp assembly includes a light source, such as a light emitting diode (LED) module, that is operable to generate light. The light source is attached to the vehicle structure, located on the interior of the vehicle adjacent to the aperture. A light guide is operatively connected to the light source. The light guide is configured to transmit light generated by the light source to preselected locations along the exterior of the vehicle structure, and diffuse the light. The light guide is attached to the vehicle structure, located on the exterior of the vehicle adjacent to the aperture in opposing relation to the light source. The cross-sectional area of the aperture formed through the vehicle structure is less than the cross-sectional areas of the LED module body and the light emitting segment of the light guide.

  • Publication number: 20080198617
    Abstract: An LED adaptive forward lighting system for an automotive vehicle comprises a headlamp housing fixed to the vehicle for mounting LED lamp units having fixed light beam directions. The LED lamp units each have mounting pivots and link pivots that are spaced from one another to provide lever arms. The mounting pivots mount the LED lamp units on a bezel within the housing. A link is provided both to the link pivots on the LED lamp units and to an axially translational shaft driven by a motor that is restrained with respect to the vehicle. When the drive shaft reciprocates, the LED lamp units rotate and shift the direction of the light beams thereof with respect to the longitudinal axis of the vehicle.
