摘要： An illumination device for a motor vehicle having a printed circuit board with a plurality of light emitting diodes disposed thereon. An optical pane and a reflector element are provided, whereby the reflector element is disposed between the printed circuit board and the optical pane. The reflector element has a plurality of segments into which the reflector element is divided. Each light emitting diode is assigned a segment so that light emitted from the light emitting diodes is reflected by the segments of the reflector element and passes through the optical pane.

摘要： The object is to improve degree of freedom in design for the cross-sectional shape of a region of light guided by the lens structure. A lens structure for a vehicle light body guides at least part of the light in the Z+ direction to both sides of the X direction, and then guides in the Y+ direction. The first reflective surface includes a first reflective surface sub part projecting from the first reflective surface main part to the X+ direction. The second reflective surface includes a second reflective surface sub part projecting from the second reflective surface main part to the X− direction. The first reflective surface sub part and the second reflective surface sub part are arranged in the Y direction in a plan view seen in the Z direction, and intersect in a plan view seen in the Y direction.

摘要： The purpose is to facilitate the adjustment of the size of a light emitting region of a lens structure. A lens structure for a vehicle light body includes a light emitting part and a base. The light emitting part includes an introduction reflective surface which causes light from the base to completely reflect as parallel light to the Z− direction, and a back-side reflective surface arranged to the Z direction in the light emitting back surface. Each back-side reflective surface has a normal direction sloping relative to the Z direction, and causes the parallel light from the introduction reflective surface to completely reflect to the Y+ direction. The light emitting surface emits light from the back-side reflective surface.

摘要： An optical element, comprising a light guide body. The light guide body comprises a plurality of light-incident parts arranged along a length extension direction of the light guide body, a light guide part and a light-emitting part; each light-incident part is provided with at least one light-incident unit; the light guide part is configured to guide light received by each light-incident unit to be emitted toward the light-emitting part; the shape of a forward projection plane of the light-emitting part is of a strip shape. The optical element can reduce the occupied space and improve the space utilization rate, facilitates reducing positioning mounting errors, has an appearance with a narrow and elongated shape, and can be applied in vehicle lamp modules, vehicle lamps and vehicles.

摘要： A light guide is provided having an elongate body extending in a longitudinal direction having a light transmission portion with a forward light exit surface and a reflective track extending opposite the light exit surface. A plurality of reflective elements are formed along the reflective track and spaced apart in the longitudinal direction. Each reflective element has a center segment and a pair of edge segments each oriented at a spread angle from the center segment toward the light transmission portion, thereby increasing a spread of light output in a horizontal direction from the light transmission portion.

摘要： A lamp for a vehicle using micromirrors includes a variable beam forming part that generates light and forms a variable beam pattern. In particular, the variable beam forming part includes a first optical part that irradiates the light; a beam pattern forming part that reflects the light of the first optical part to form the variable beam pattern; and a second optical part that transmits the light reflected from the beam pattern forming part. The beam pattern forming part includes a reflection part including a plurality of micromirrors; and a housing that accommodates the reflection part. The housing includes an anti-reflection member to prevent secondary reflection of the light having been reflected by the reflection part.

摘要： A configurable vehicle lighting module system includes a shared lens that provides a first light pattern for a first vehicle lighting function and a second light pattern for a second vehicle lighting function. The shared lens includes a mounting axis as a reference for mounting on a vehicle. First internal optics direct light toward the shared lens to provide the first light pattern; second internal optics direct light toward the shared lens to provide the second light pattern. A coupling system joins the shared lens with either the first internal optics to form a first module configuration for the first vehicle lighting function or with the second internal optics to form a second module configuration for the second vehicle lighting function. The shared lens conceals physical differences between internal optics configurations such that the first and second light module configurations appear the same when viewed along the shared lens.

摘要： A headlight for vehicles, with a light source, a reflector arrangement containing at least one reflector module, a first reflector, which has a reflector surface having a first focal point and a second focal point, the light source being arranged at the first focal point, and a second reflector, which has a reflector surface having a focal point that coincides with the second focal point of the first reflector. The first reflector is arranged in front of the light source in the main radiation direction, the reflector surface of the first reflector being curved, with a first opening portion arranged counter to the main radiation direction and with a second opening portion arranged in a manner offset by 90° in relation to the first opening portion and facing towards the second reflector. The reflector surface of the second reflector has free-form parts such that light striking the reflector surface of the second reflector is reflected in such a way that a light distribution having a predetermined light/dark boundary is produced.

摘要： The present invention relates to a vehicle lamp module comprising a lens, a shading plate with a cut-off line structure, a low beam module, and a high beam module. Light emitted by the low beam module is suitable for interception by the shading plate and then emission to the lens to form a low beam type. Light emitted by the high beam module is suitable for interception by the shading plate and then emission to the lens to form a main high beam type located above a light and shade cut-off line. The vehicle lamp module further comprises an auxiliary high beam module. Light emitted by the auxiliary high beam module is suitable for interception by the shading plate and then emission to the lens to form an auxiliary high beam type located below the light and shade cut-off. The vehicle lamp module provides high beam with more uniform brightness.
