摘要： A vehicle headlamp includes a reflector having plural reflecting surfaces arranged in a left-right direction, and n light sources which are arranged in the left-right direction and emit light toward any one of the reflecting surfaces. At least two adjacent light sources are provided as a common light source which emits light toward a same reflecting surface. n illumination patterns which illuminate different regions in the left-right direction are formed by light emitted from the n light sources, respectively, and are taken as a first to n-th illumination patterns in this order in the left-right direction. At least half of areas of illumination patterns of an immediately-following number and an immediately-preceding number overlap each other in the left-right direction. Focal lengths of the plural reflecting surfaces are set such that adjacent illumination patterns which do not overlap each other are formed by light emitted from the common light source.

摘要： Provided is a vehicular lamp that forms a light distribution pattern for traveling having a lower end portion overlapping an upper end portion of a light distribution pattern for passing and is downsized with a simple configuration. The vehicular lamp includes a projection lens that projects light emitted from a first light source to form the light distribution pattern for passing and projects light emitted from a second light source to form the light distribution pattern for traveling. A lower lens part and an upper lens part are set in the projection lens about a lens axis as a center, a lower focus is set on the lens axis in the lower lens part, and an upper focus shorter in focal length than the lower focus is set on the lens axis in the upper lens part.

摘要： The invention relates to a lighting device (1) for a motor vehicle headlight for generating a light pattern with a light-shadow line, wherein the lighting device comprises a light source (10), a light-permeable body (100), a light injection element (101) for injecting light which the at least one light source (10) emits, and a projection device (500). The light-permeable body (100) has an aperture device (103) with an aperture edge region (104). A light beam (S2) spreading in the optical element (110) is displayed by the projection device (500) as a light pattern (LV) with a light-shadow line (HD), with the light-shadow line (HD) being determined by the aperture edge region (104) of the aperture device (103). At least one light guide element (200, 300) is arranged on the optical element (110), which light guide element has a light guide element light incoupling face (201, 301) and a light guide element light outcoupling face (202, 302), the at least one light guide element (200, 300) being arranged on the optical element (110) in such a manner that light (S3) is injected from the light injection element (101) via the light guide element light incoupling face (201, 301) into the at least one light guide element (200, 300), spreads within this, and enters the optical element (110) again via the light guide element light outcoupling face (202, 302), the light guide element light outcoupling face (202, 302) of the at least one light guide element (200, 300) issuing into the optical element (110) in such a manner that the at least one light guide element light outcoupling face (200, 300) lies beneath the aperture edge region (104) as considered in the vertical direction (Z), so that the light rays (S5) re-entering the optical element (110) from the projection optical assembly (200) are projected as a sign-light light beam (SL) into a region (B) of the light pattern located above the light-shadow line, and are displayed in the light pattern as a sign-light light pattern (SV), for instance.

摘要： A lighting device includes: a light source having a light-emitting surface; a reflector having a reflective surface configured to reflect light emitted from the light source; and a lens on which light reflected by the reflective surface is incident. The reflective surface is composed of a portion of a spheroidal surface that includes a first focal point located on the light-emitting surface and a second focal point located between the reflective surface and the lens. The reflective surface intersects a major axis of the spheroidal surface. A value obtained by dividing a first distance, which is a distance between the first focal point and the second focal point, by a second distance, which is a distance between the first focal point and an intersection point of the reflective surface and the major axis, is 7 or greater.

摘要： A vehicle lighting unit includes: a heat sink (12); a light emitting element disposed in the heat sink (12); and a reflector that is disposed above the light emitting element, and reflects emitted light emitted forward from the light emitting element. The heat sink (12) includes a base portion (22) for disposing the light emitting element on a pedestal portion (21); and a fin portion (23) that is disposed on a back surface of the base portion (22), and radiates heat generated by the light emitting element. The back surface of the base portion (22) is inclined with respect to the pedestal portion (21). In the heat sink (12), a thickness of the base portion (22) is thicker on a lower side of the light emitting element than on a rear side of the base portion (22).

摘要： An optical unit includes: a light source; a rotating reflector configured to be rotated in a single direction with the rotational axis as the center of rotation while reflecting light emitted from the light source; and a projector lens configured to project light reflected by the rotating reflector in the light irradiation direction. The projector lens has a first lens region LR1 that defines the first focal plane and a second lens region that defines the second focal plane that differs from the first focal plane. The light source is arranged such that, when the rotating reflector is set to the first rotational position, its virtual position is in the vicinity of the focal plane, and such that, when the rotating reflector is set to the second rotational position, its virtual position is in the vicinity of the focal plane.
