  • Patent number: 8616147
    Abstract: A disclosed instrument cluster includes dial gauges with an illuminated pointer including light reflecting features for uniformly distributing light within the pointer. The light deflecting structure directs light toward tip of the pointer by reflecting the light of each of the first and second sides. The light deflecting structure provides the desired distribution of luminescence by directing light toward the sides surfaces of the pointer.

  • Patent number: 8365680
    Abstract: Provided is a pointer illumination structure which is simple, and in which a rotary part including a pointer body can be made lightweight. A containing cover 20 of a pointer movement 1 contains a rotation driving mechanism including a rotor 32 and an intermediate gear 33, an output gear 34, and so on. The rotation driving mechanism transmits rotation based on a measured amount to the output gear 34, and rotates a pointer body 10 supported by a bearing 22c, by way of the output gear 34. The bearing 22c rotatably supports a shaft 11 of the pointer body 10. A pointer 12 of the pointer body 10 indicates a measuring value according to rotation of the pointer body 10 around the shaft 11. A light source 13 is provided for illuminating the pointer 12 of the pointer body 10.
