摘要:
A headlight for a motor vehicle having a housing, a semiconductor light source, a cooling body, an optical system which collects and directs light of the semiconductor source, a securing frame which is mechanically connected to the housing and which holds the semiconductor light source with the cooling body and the optical system in the housing, and having an interface between the first part which forms a complex light source and comprises at least the semiconductor light source and the cooling body, and a second part which comprises at least the holder, wherein the first part is connected to the second part at the interface so that it can be separated without destruction. The headlight is defined by the fact that the first part which forms the complex light source has, in addition to the semiconductor light source and the cooling body, at least one optical system which collects and directs a light of the semiconductor light source.

The invention relates to a light module for motor vehicle headlamps (10), comprising a laser light source (12) for emitting a primary light bundle (14) in a primary spatial angle sector about a primary beam axis (16), a photoluminescent element (18), which is arranged in such a way that the primary light bundle (14) that can be emitted by means of the laser light source (12) hits the photoluminescent element (18) and which is designed in such a way that a secondary light distribution (20) can be emitted as a result of the incident primary light bundle (14) by utilizing photoluminescence. The light module also comprises an emission optical device (22), which is designed in such a way that the secondary light distribution (20) can be converted into an emission light distribution of the light module (10). A detecting device (34) is provided, which is designed and arranged in such a way that the detecting device can detect when the radiation intensity of light bundles that extend in the beam path downstream of the photoluminescent element (18) in the primary spatial angle sector about the primary beam axis (16) exceeds a safety limit.

The invention relates to a motor vehicle headlight (12) comprising a multifunctional projection module (14) that is equipped to convert light from a first light source (16) in a first optical path into a first light distribution that lies in the area in front of the projection module (14) and to convert light from a second light source (22) in a second optical path into a second light distribution that lies in the area in front of the projection module (14). An aperture 26 that has an aperture edge (40) consists of a composite structure made up of a transparent supporting body (30) and a layer (32) that is made of a different material than the transparent supporting body (30), said transparent supporting body (30) having a light emergence face (36) and an aperture surface (38) which is delimited by the light emergence face (36) and to which the layer (32) adheres.

The invention relates to a motor vehicle headlamp (10), comprising a multi-function projection module (14), which is designed to convert light from a first light source (16) into a first light distribution (34) by means of a first primary lens system (18) in a first beam path bounded by an aperture edge (26), and to focus light from a second light source (20) into a beam waist (44) and convert said light into a second light distribution by means of a second primary lens system (22) in a second beam path, the second light distribution having a predetermined central point (56). The projection module is characterized by a mirror (30), which is arranged in the second beam path between the beam waist (44) and the projection lens (28) in such a way that the mirror produces a virtual mirror image of the beam waist (44) at the focal point of the projection lens.
