  • Bright pointer for instrument cluster
    Patent number: 6974220
    Abstract: An instrument display for a vehicle dash includes a unique light source and light guide assembly. The light source is incorporated directly into the light guide. A non-contact magnetic coupling transfers power from a circuit board to the light source. A textured surface is formed on one portion of the external surface of the light guide to evenly illuminate the light guide. Also, surface roughness on an opposing external surface portion of the light guide is varied depending on the length of the light guide to provide similar luminance for light guides having different lengths.
    Type: Grant

    Date of Patent: December 13, 2005
    Assignee: Siemens VDO Automotive Corporation
