The projection lens has a joint surface and is transparently formed. The lens holder has a welding surface that is joined to the joint surface and is transparently formed. The welding surface is irradiated with laser light having a wavelength of 1,550 nm to 1,640 nm transmitted through the projection lens to join the projection lens and the lens holder with each other.

A light module of a light unit of a vehicle, having a light generating unit, an optical system, a cover plate, a cover frame and a carrier, wherein in an assembled state of the light module, the light generating unit, the optical system and the cover plate are arranged in the aforementioned order between the carrier and the cover frame, and wherein the cover frame has a plurality of positioner for positioning the light generating unit, the optical system and the cover plate relative to the cover frame.

A vehicle lamp includes a light source and a compound optical lens that emits light forward. The compound optical lens has an incidence surface, an emission surface, and a shade part. The emission surface emits the light received by the incidence surface forward. The shade part is disposed between the incidence surface and the emission surface. The compound optical lens has first and second reflector surfaces. The first reflector surface reflects light forming a first light distribution pattern toward the emission surface. The second reflector surface reflects light forming a condensed-light distribution pattern toward the emission surface. The width of the first reflector surface is larger than the width of the second reflector surface in a vehicle width direction at a position where the first reflector surface and the second reflector surface are adjacent to each other.

Lighting device of a motor vehicle headlamp comprising a projection optics system (1) and a light source unit (2), wherein the light source unit comprises a surface (20), wherein the light source unit (2) can generate a lighting pattern on the surface (20), wherein the lighting pattern which can be generated on the surface (20) can be projected in front of the lighting device in the form of a light distribution by means of the projection optics system (1), wherein the light source unit (2) comprises a support structure (3), wherein the support structure (3) has an opening (30), wherein the opening (30) is arranged and designed to match the surface (20) and the lighting pattern can be generated at least on one side (201) of the surface (20) facing the projection optics system (1), wherein the projection optics system (1) has guiding elements (10) and the support structure (3) has elongated guides (31) corresponding to the guiding elements (10), wherein the guiding elements (10) are arranged in such a way that they can be guided in the elongated guides (31) along a longitudinal direction (X) of the elongated guides (31), wherein the projection optics system (1) rests on the support structure (3) and is movable along the longitudinal direction (X).

An assembly for projecting a light beam includes a first sub-assembly for generating light rays, and a second sub-assembly comprising a converging lens. The first sub-assembly is arranged upstream of the second sub-assembly such that the light rays coming from the first sub-assembly are sent to the converging lens and such that the light rays emerging from the converging lens form the light beam. According to the invention, the projection assembly includes at least one connection system connecting the first sub-assembly to the second sub-assembly and allowing at least one translational movement of the first sub-assembly and the second sub-assembly relative to each other in a first longitudinal direction (X). Moreover, the connection system comprises a locking member that is movable between a first position in which the first sub-assembly and the second sub-assembly are motionless with respect to each other and a second position enabling the translational movement.

A light source unit provided with a light-emitting element as a light source is attached to a rear wall section of a housing. The light source unit is attached to the housing, in the state where a socket is inserted in an opening formed in the rear wall section and an elastic seal member attached to the front end of the socket is pressed against the rear wall section. A rib extending toward a lamp rear side so as to surround at least the upper half section of the opening is formed on the rear wall section of the housing.
