发明名称 Tip to tail to center pointer
摘要 A pointer includes a diffuser that receives light from a single light source and reflects light toward a tip and a tail of the pointer uniformly regardless of radial position. Transmission of light toward a tip and a tail of the pointer is accomplished by a reflective surfaces within the pointer. A diffuser is disposed adjacent the reflective surfaces to provide an even luminance throughout the pointer. The light source produces light that is transferred through a translucent shaft toward the diffuser. The diffuser is aligned with light transmitted through the shaft. The light source is disposed along the axis such that rotation of the pointer does not change the relative orientation between the light source and the reflective surfaces. The consistent relative orientation between the light source and the pointer substantially eliminates differences in illumination levels produced during rotation about the axis.
