摘要： An optical reading device for a pointer instrument which has a pointer and a scale face or dial with different degrees of reflectance in each case, includes an illumination device for illuminating the scale face or dial and a plurality of light sensor elements which are arranged in a circular arc about the rotational axis of the pointer in order to detect the light of the illumination device reflected back by the scale face or dial, wherein the illumination device is configured to uniformly illuminate the scale face or dial and each light sensor element is configured with an isosceles triangle outline, where each light sensor element is offset with respect to one another by half of the base width in the circumferential direction of the circular arc.

摘要： Light emitted from laser light source is divided by prism into two light flux and light flux corresponding to light emitted from slope and slope. Light flux and light flux are diffused by diffusion plate and diffusion plate to become light flux and light flux. By overlapping light flux and light flux, a radiation distribution with a wide angle and high light intensity can be obtained.

摘要： Systems and methods are disclosed and include a needle control module that includes a processor configured to execute instructions stored in a nontransitory computer-readable medium, a motor driver circuit in communication with the needle control module, the motor driver circuit controlling a stepper motor attached to a needle, and a housing enclosing the needle control module, the motor driver circuit, and the stepper motor, the housing being physically attached to a display of a vehicle. In response to the needle control module receiving a signal representing vehicle state information, the needle control module is configured to instruct the motor driver circuit to control movement of the stepper motor and adjust a position of the needle based on the signal.

摘要： A pointer device has a light-guiding body, including a shaft, a hub coaxial with the shaft and having a rear surface covered by a shield, and a pointer, which projects radially from the hub. A cap is defined by at least one piece separate from the light-guiding body and is mounted on the hub in a fixed position. The hub has an emitting surface, a first reflecting surface configured to reflect and direct a first light flow from the shaft to the pointer, and at least a second reflecting surface, which is configured to reflect and direct a second light flow from the shaft to the emitting surface and is, at least in part, set apart from the first reflecting surface. The cap has at least one light-permeable area, aligned with the emitting surface, and a barrier arranged radially between the emitting surface and the first reflecting surface.

摘要： An information display portion indicates vehicular information relevant to a vehicle. A display plate being translucent is located on a viewing side relative to the information display portion. A reflective portion formed in the display plate is configured to be illuminated in a predetermined shape by light emitted from a light source unit. The reflective portion being illuminated is overlapped on the vehicular information indicated by the information display portion and viewable on the viewing side.

摘要： A pointer to indicate gradations formed in a dial of a vehicle instrument cluster includes: a pointer blade to receive and emit light received from the lower portion of the dial when a blade body formed integrally with a blade arm is rotatably supported above the dial; a pointer weight disposed adjacent to a rear surface of the blade body and having a light through-hole to allow light received from the lower portion of the dial to pass through the pointer weight; a light pin part extending to the rear surface of the blade body from one end of the blade arm and inserted into the light through-hole; and a weight supporter, fit between the pointer blade and the pointer weight and below the light through-hole to receive light from the lower portion of the dial and transfer the light to the pointer blade.

摘要： A vehicle instrument panel assembly includes a light source, a pointer, and a sensor. The light source is configured to emit light from a display surface of the assembly. The pointer overlies the display surface and is movable about an axis to an angle to point to indicia on the display surface. The pointer defines a hub portion and a needle portion that extends from the hub portion. The hub portion overlies the light source and includes a light-guide that guides light from the light source into the needle portion whereby the needle portion is illuminated. The sensor is located proximate to the hub portion. The sensor is configured to detect that the pointer is present regardless of the angle of the pointer.
