A laser point projecting device including a light source assembly that projects first and second positioning points respectively along two directions of a straight line. The laser point projecting device includes a housing part forming a sleeve around a body part. The body part and the housing part are displaceable relative to each other. The light source assembly is switched off when the body part is displaced to a first position along the direction of projecting the first positioning point; and the light source assembly is activated when the body part is displaced to a second position along the direction of projecting the second positioning point. The housing part has at least one opening at the end along the direction of projecting the first positioning point, and a hollow space formed between the end of the housing part close to the first positioning point and the body part.

A pointer device for an indicator instrument, in particular for a vehicle, is provided with a light-guide body defined by a single piece, which, in use, receives light from a light source and has a hub and a pointer radially protruding from the hub; the hub has a surface covered by a shield and a light transmission portion, which, on the opposite side, ends with at least one light emission area; the device is provided with a cap defined by a single piece, which is separate from said light-guide body and has an intermediate portion and a lateral portion arranged in an inner and outer radial position, respectively, relative to the light transmission portion; the cap has at least one through opening aligned with the light emission area and connection portions extending radially and joining the intermediate portion to the lateral portion.

A resin molded article is applied to a vehicle display device for displaying information on a vehicle, and a high gloss region having a relatively high surface glossiness and a low gloss region having a relatively low surface glossiness are integrally molded. As a result, since the high gloss region and the low gloss region having different surface glossiness are integrally formed in a single resin molded article 1, the resin molded article and the vehicle display device obtain an effect such that various appearances are created with a simple structure.

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.

A light guide pointer and a light emitting pointer device which can reduce luminance unevenness at a light emitting face are provided. A lower face of a main pointer portion includes a separating face extending away from a light emitting face, thus light reflected by a front inclined portion of a light control space, that is not likely to travel in a direction away from the light emitting face, is not likely to reach to a corner which is a boundary between the separating face and a recessed portion. Consequently, light is not likely to be reflected by the corner between the separating face and the recessed portion, thereby preventing luminance to be partially high at the light emitting face and thereby reducing luminance unevenness.

A pointer for a gauge or an instrument cluster assembly is provided. The pointer is formed of a light conducting material. In one form, indicia are disposed about the axis of rotation and/or on a surface, the plurality of indicia configured to be selectively illuminated by the pointer. A second end of the pointer may be configured to be selectively rotated adjacent to each indicium of the plurality of indicia and to illuminate the indicia when the light guide pointer is disposed adjacent to the indicia. The second end may be wider than a first end of the pointer. In some variations, the pointer may have a fan shape, and the indicia may be configured as tick marks defining a bar graph. In some forms, opaque material may be disposed on the pointer, the opaque material defining a plurality of indicia on the pointer.

An illuminated pointer for a vehicle instrument cluster provides a more uniform light by propagating light from a source, through an elongate, light-transmitting prism formed to have multiple, inclined light-reflecting surfaces. Each surface being at a different angle, reflects light at a slightly different angle producing a corresponding number of refracted light maxima along the length of the prism. A more uniform refracted light is produced.

A light guide pointer and a light emitting pointer device which can reduce luminance unevenness at a light emitting face are provided. A lower face of a main pointer portion includes a separating face extending away from a light emitting face, thus light reflected by a front inclined portion of a light control space, that is not likely to travel in a direction away from the light emitting face, is not likely to reach to a corner which is a boundary between the separating face and a recessed portion. Consequently, light is not likely to be reflected by the corner between the separating face and the recessed portion, thereby preventing luminance to be partially high at the light emitting face and thereby reducing luminance unevenness.

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.

An illuminable pointer assembly for an instrument panel includes a transparent or translucent base, a transparent or translucent pointer blade, and a hub mounted on the base and supporting the pointer blade. The assembly is miniaturized or capable of being miniaturized by integrating reflectors into a lower surface of the pointer blade to internally reflect light propagated upwardly through the base in a lateral direction to uniformly illuminate the pointer blade.
