A headlamp () for a vehicle, comprising at least one light source (), a primary optical system () for generating a lighting image, and an optical imaging system (), wherein the lighting image can be projected onto the roadway as a light image by means of the optical imaging system (), and the primary optical system () has a plurality of light guiding elements () and a support layer (), wherein the light guiding elements () are arranged on a rear face () of the support layer (), and the lighting image can be generated on a front face () of the support layer (), the light guiding elements () are arranged adjacently to one another or in an overlapping manner in a row in an axis direction (y) and form at least one line (), wherein each light guiding element () has a light inlet surface () for coupling in light from at least one light source () and a light outlet surface () for coupling out light, wherein the totality of the light guiding elements () of the at least one line () have a common border () which is constantly curved on at least one face oriented substantially along the axis direction (y) and together with the support layer () forms a section curve with a curved curve course ().

Headlight for a vehicle

The invention relates to a light guide unit () for a light-emitting unit () for a projector lamp, in particular a motor vehicle headlamp, wherein the light-emitting unit () comprises a plurality of light sources (), the light guide unit (), and a downstream projection lens (), wherein the light guide unit () has a plurality of light guides (), wherein each light guide () has a light exit surface (), and wherein each light source () couples light precisely into a light guide () assigned thereto, and wherein adjacent light guides () are separated from one another by separating walls (). In accordance with the invention the light guide unit () comprises an accommodating element (), which accommodating element () has an accommodating opening () which passes completely through the accommodating element () in the light exit direction, and furthermore comprises at least one light guide body (), which at least one light guide body () is in the form of a component formed separately from the accommodating element (), in which at least one light guide body () at least some of the light guides () of the light guide unit () are formed, and wherein the at least one light guide body () is inserted into the accommodating opening () of the accommodating element ().

Light-emitting unit comprising a light guide unit for a projector lamp

The invention relates to an illuminating device () for a motor vehicle, comprising two or more light modules (), which light modules () are provided to generate a common light distribution, and a common supporting body (), on which the at least two light modules () are fastened, wherein at least one of the light modules () is mounted on the supporting body () so as to be pivotable about at least one axis (H, V) with respect to the supporting body (), and wherein the at least one pivotable light module () is mounted on the supporting body () in an articulated manner by means of an articulation () so as to be pivotable about the at least one axis (V, H), wherein at least one prestressing device () is also provided, by means of which the at least one adjustable light module () is held in a prestressed manner on the supporting body () pivotably about the articulation ().

Lighting device for a motor vehicle

The invention relates to a lighting device () for a motor vehicle headlight, comprising a number of light sources (), at least one attachment optical unit (), having a light entrance surface () and a light exit surface (), wherein the at least one attachment optical unit () comprises a plurality of light-guiding bodies (), and wherein each light-guiding body () has a light entrance surface (), into which in each case at least one light source () feeds light, and wherein the light-guiding bodies () lead into the common light exit surface (). According to the invention, at least one, preferably exactly one, position holder () is provided, by means of which the light entrance surfaces () of the light-guiding bodies () of the at least one attachment optical unit () are held in position in relation to the light sources (). Alternatively or additionally, provision can be made for the light exit surface () of the at least one attachment optical unit () to be provided with a transparent light plate () for the dimensional stabilization of the at least one attachment optical unit ().

Lighting device for a motor vehicle headlight

The invention relates to a lighting device () for a motor vehicle, comprising at least one light unit (), for example two or more light units (), wherein each light unit () comprises:

A vehicle headlight includes at least one stationary reflector and at least one reflector adjustable with respect to the at least one stationary reflector. The headlight includes at least two light sources including at least one LED, wherein each of the reflectors is assigned at least one of the light sources, and an assembly body for fastening the at least one stationary reflector and the at least two light sources. The assembly body includes a main body, on which the at least one stationary reflector is assembled. and an exchange body, on which the at least two light sources are fastened. The main body has a through-opening for insertion of a light source support element from the side facing away from the reflectors. Referencing or positioning means are provided on the exchange body in order to fasten the two bodies to one another in a positionally accurate manner.
