Abstract: A pointer assembly includes the pointer and hub that are both illuminatable. The hub includes a main portion with a concave surface. A reflector is partially received within a slot through the concave surface and is supported on top of the hub. The reflector includes a reflective surface that directs light onto the concave surface. Light from a light source is directed by separate reflective surfaces on the pointer and the reflector to illuminate both the hub and the pointer.

Abstract: An example light guide assembly for illuminating a display of an instrument cluster includes a light receiving portion, a light propagating portion and a reflective surface between the light receiving portion and the light propagating portion. The light receiving portion extends along a first axis, and the light propagating portion extends along a second axis which is transverse to the first axis. The reflective surface includes a stepped surface transverse to the reflective surface.

Abstract: An instrument cluster assembly includes a first instrument cluster graphic and a second instrument cluster graphic. The second instrument cluster graphic is superimposed on the first instrument cluster graphic.

Abstract: An example light guide assembly for illuminating a display of an instrument cluster includes a light receiving portion, a light propagating portion and a conical surface positioned between the light receiving portion and the light propagating portion. An exterior surface of the light propagating portion includes a plurality of lobes that uniformly illuminate the display as light propagates from the light receiving portion to the conical surface and through the light propagating portion.

Abstract: An instrument gauge display for a vehicle dash includes a transparent dial having an upper surface partially covered by black paint and a lower surface covered with white paint. Uncovered areas on the upper surface define a plurality of graphical images that indicate a vehicle operating condition. A light guide, supported within a light housing, is positioned underneath the dial. The light housing and at least one light source is mounted to a printed circuit board, which is supported underneath the light guide by a vehicle structure. The light guide includes a plurality of scattering elements that are positioned generally underneath each of the graphical areas on the dial. The light source cooperates with the light guide and scattering elements to improve the light efficiency.

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.
