    Standard light source Laser diode
    The invention relates to a light source module for a Fahrzeu gscheinwerfer, wherein the light source module at least one laser light source and at least one excitable by illumination with laser light for the emission of visible light luminous element which is irradiated by the laser light source comprises. The invention further relates to a vehicle headlamp with at least one such light source module.
    In the prior art, various types of vehicle headlamps are known in which light source modules with, for example, discharge lamps or halogen light sources can be inserted and fastened. For this purpose, usually appropriate recordings are provided in the reflectors or reflector adapters.
    The usual today light source modules each contain a light source and an igniter, which form a common assembly and therefore easily and reproducibly mounted or can be easily replaced in case of malfunction. It is ensured that when inserting a new light source module, the light source again in the right place -. with regard to the reflector - is located
    For energy saving reasons and to reduce the space requirement of vehicle headlamps, the use of laser light sources such as semiconductor lasers is increasingly being tested, since they are advantageous in this regard. In order to make the laser light usable for a vehicle headlight, a light source, a so-called phosphor, is irradiated with a laser light source, which is thereby excited to emit visible light. Such solutions show US 2011/0157865 A1, US 2011/0194302 A1 and US 2011/0280033 A1.
    The common light module solutions can not be operated with such light sources. It is therefore an object of the invention to provide a light source module that can be operated with a laser light source.
    This object is achieved with an aforementioned light source module according to the invention that the laser light source and the luminous element spaced from each other are arranged on a support element. -2- P12417
    The light source module according to the invention enables a standardized laser light source for vehicle headlights, the positioning accuracy between the laser light source and the light element being ensured by the common arrangement of the laser light source and the light element on a carrier element. The light source module can be inserted like conventional modules in the direction of the optical axis of a vehicle headlight or its reflector from behind. As a result, an easy installation or replacement is possible, while the reproducible positioning, in particular of the lighting element is ensured within the vehicle headlamp.
    For example, semiconductor lasers or laser diodes of known type can be used as the laser light source, the wavelength of the emitted light being in the range from 200 nm to 450 nm. For example, it can also be a light source array with a plurality of light sources, in particular laser diodes. In this case, a color match between the different light sources can be provided. By way of example, the light element is an arbitrary phosphorus converter, with all these materials having in common that they can be excited with laser light for emitting visible light, in particular white color.
    The carrier element can be designed as desired, for example made of plastic. Conveniently, the carrier element is made of a thermally conductive material and / or at least partially made of a transparent material Various conventional materials can be used, for example, the support element in "aluminum die casting " or realized as a heat pipe comprising a heat sink of known type. Also possible are various metals, metallic alloys or anthracite-hzw. graphitic polymers. The material or the embodiment is to be chosen such that a heat dissipation away from the light-emitting element is ensured. The heat generated during operation of the laser light source or the light-emitting element can thus be dissipated via the carrier element. The waste heat can be quite considerable, since laser light sources are used with powers of currently up to 3 W, with some of the power is delivered in the form of heat. The heat dissipation is advantageous because the radiation characteristic of a laser diode, as used here, unlike LEDs is highly dependent on the temperature. -3- PI2417
    When the support element is at least partially made of a transparent material, the incident laser light or the light originating from the luminous element can be deflected and thus made visible in combination with irregularities (microstructures, material inclusions, or the like) carried out in the support element or on its surface. Laser light, which leaves the laser light source uncollimated, is scattered and mirrored in the transparent part of the carrier element, so that the light can be perceived outside the vehicle headlight. For example, when using a blue laser light source, an eye-endangering blue glow can be generated that can be used as a design element.
    Advantageously, the light source module has means for releasable mounting in a vehicle headlight, wherein the means are arranged in particular on the carrier element. In this case, latching elements can be used, for example, which interact with corresponding latching receptacles, the latching elements respectively being able to be arranged on the light source module and the latching receptacles on the vehicle headlight (for example in the reflector or reflector adapter) or vice versa. Also possible are tongue and groove combinations over which the light source module can be inserted into a vehicle headlight. Such means for releasable assembly are known in the art and therefore will not be further elaborated here. Thus, the light source module according to the invention can be mounted like conventional modules in a vehicle headlight or its reflector or reflector adapter.
    In a variant of the invention, the luminous element is arranged on the carrier element such that it can be arranged in the mounted state in a focal point of a reflector of the vehicle headlamp. This ensures optimum utilization of the light emitted by the luminous element
    Advantageously, the light source module and / or the laser light source have reference means for referencing the light source module and / or the laser light source in a vehicle headlight, in particular a reflector of a vehicle headlight. This ensures that the optimum positioning of the module or its luminous element is reproducible when installing the light source module in a headlight. In a variant of the invention, the reference means are as with corresponding guide receiving devices of a vehicle headlamp, in particular a reflector of a vehicle headlamp , cooperating guide devices executed In a further variant of the invention, the reference means are designed as executed on the laser light source and / or the support element reference plane with at least three support surfaces which cooperate with corresponding support surface recordings on the vehicle headlamp, especially on the reflector of a vehicle headlamp. In yet another variant of the invention, the reference means are designed as at least one dowel pin and at least one dowel hole, wherein the dowel pin are arranged on the laser light source and / or the carrier element and the dowel hole is arranged on a vehicle headlamp, or vice versa
    Advantageously, on the side facing away from the laser light source side of the light emitting element disposed on the support element concentrator optical element is provided which shields the light element in the mounted state in Hauptabstrahlrichtung the vehicle headlamp and / or on its side facing the luminous element has a reflective layer. The concentrator optical element can be made of glass, for example, which is provided on its side facing away from the laser light source side with an opaque coating.
    The Konzentratoroptikelement may further be made of plastic or metal, which are preferably opaque. This prevents the light emitted by the light-emitting element from leaving the vehicle headlight in an uncontrolled manner in the main emission direction and thus impairing the light image. In addition, the concentrator optical element according to this variant serves as a safety precaution: It shields the laser light as a cap against the environment and prevents its escape and thus the risk of uninvolved road users. When providing a reflection layer facing the luminous element, the light emitted by the luminous element on all sides (in particular in the direction away from the laser light source) is utilized and at the same time optically preformed - the concentrator optic element thus acts as a reflector.
    In a variant of the invention, the luminous element is arranged in an optical element arranged on the carrier element, preferably in a blind hole or in a cavity, wherein the optical element has at least one reflection layer reflecting light in the direction of the laser light source at least on a side remote from the laser light source. or at least associated with an opaque absorption layer. The -5- P12417
    Reflection layer and / or the opaque absorption layer are preferably mounted directly on the optical element · The optical element thus has a receptacle for the luminous element and a reflection layer and / or absorption layer in a common component.
    In addition to the execution as a blind hole, the recess can also be designed as a cavity, that is enclosed on all sides by the optical element. As a result, the light-emitting element is protected against environmental influences. The optical element may be made of glass or transparent plastic, for example, so that the light of the laser light source can strike the luminous element. When providing an opaque coating, the optic element (as well as the concentrator optic element) acts as a cap for the laser light and the light emitted by the luminous element. This opaque coating may also be used, for example, for design purposes, e.g. to place manufacturer logos.
    The optical element or the concentrator optical element can be embodied as a free-form surface with at least one focal point. Thus, the reflective layers or the reflection layer applied thereto also have the form of a free-form surface with the corresponding reflection behavior. The converted light is preformed. Thus, the light of the luminous element, which is emitted in the direction of the main emission direction of the vehicle headlight, can be made even better usable.
    In a further variant of the invention, the side of the optical element facing the laser light source is covered at least partially, but in particular in a region below a horizontal plane passing through the luminous element, by an opaque diaphragm device, for example in the form of an opaque coating.
    The diaphragm device allows the generation of a light-dark transition, whereby various light functions such as low beam, fog light, etc. can be realized. In the case of a dimming light, it is necessary, for example, that the luminous element is sharply demarcated geometrically and photometrically. This purpose is served by the abovementioned diaphragm device, which is embodied, for example, as a coating, vapor deposition or separate component. The diaphragm device, together with correspondingly designed reflection regions, causes the light emission reflected in the optical element to exit above the illuminated element and thus be usable for the vehicle headlight.
    Basically, the said invention is implemented as a free-jet concept, the laser light source therefore radiates directly onto the luminous element. In a variant of the invention, at least one light-guiding element is arranged between the laser light source and the luminous element. In this case, this light-conducting element consists of a light-conducting material, for example plastic (for example Plexiglas), and can be of any shape, for example tubular, conical or cylindrical. An embodiment as a funnel-shaped concentrator element, for example made of glass, is possible. The light-guiding element can also be provided with irregularities (microstructures, roughening on the surface, scattering elements in the interior, etc.) which deflect the laser light and thus cause the light-conducting element to shine, which can be used as a design element. For example, when using a blue laser light source such a blue glow can be generated.
    In a variant of the invention, the carrier element has at least one carrier base with at least one laser light source and at least one carrier arm emanating from the carrier base with at least one luminous element. Conveniently, the support arm is designed starting from the support base U-shaped, wherein the at least one luminous element arranged at the furthest from the support base on the laser light source side facing the support arm. This makes it possible to realize a particularly compact light source module - the area in which the laser light beam passes is shielded by the U-shaped design
    In order to dissipate the waste heat arising during operation of the laser light source, the laser light source is advantageously connected to at least one cooling element, which is embodied in particular as a heat sink and / or aeration device. Conveniently, the cooling element connected to the laser light source is arranged on the carrier element. The cooling element can be, for example, water cooling, fan unit or heat pipe is possible, but is also an embodiment, for example, with cooling fins, in a variant, the carrier element is designed to conduct heat as described above, so that in combination with the cooling element just described a particularly efficient dissipation of the heat produced by the light source module is ensured -7 - P12417
    Malfunctions of the light source module, such as the laser light source, in addition to disadvantages for the operation also lead to a risk to other road users. Therefore, in a variant of the invention, at least one sensor element for detecting a malfunction of the laser light source and / or the carrier element is disordered on the carrier element. The sensor element is at least one of the following sensor devices: optical sensor for detecting a deviation of the laser light emitted by the laser light source from the proper beam direction; optical sensor for detecting malfunction of the luminous element; mechanical sensor for detecting damage to the carrier element and / or the luminous element and / or the optical element and / or the concentrator optical element.
    Advantageously, the carrier element has an absorbent surface in the area around the luminous element. Thus, an additional safety function can be realized because in a malfunction - if, for example, the orientation of the laser light source due to an adjustment of the source or possibly a break of the support element changes - when the laser beam hits the light element off the light absorbing and not reflected uncontrollably. Such an absorbing or non-reflecting surface is favorably realized in the region in which the laser light can strike in the event of malfunctions or in the vicinity of the luminous element.
    In a variant of the invention, the light source module has at least one safety switching device which prevents activation of the light source module or the laser light source of the light source module prior to installation of the light source module in a vehicle headlight. This may, for example, be a contact switch which releases the startup of the laser light source only in the correct position in the vehicle headlight or in the reflector of a vehicle headlight. Another possibility is a coding resistor or a bridge which can be integrated in the cable harness or in the lighting unit (mechanical and / or electronic) and the commissioning releases only when the headlamp or the light module are installed in the vehicle.
    The object of the invention is further solved by a vehicle headlamp mentioned above with at least one light source module according to one of the variants described above. In a variant of the invention, at least one reflector or reflector adapter -8- P12417 is provided with at least one receptacle for the light source module. The vehicle headlamp designed in this way is suitable for meeting the legal requirements of ECE, SAE, CCC, etc.
    As mentioned above, the receptacle may have means for releasably mounting the light source module, that is, for example, be provided with latching elements which interact with latching receptacles on the light source module, or vice versa Other solutions known in the art for detachable mounting are possible.
    In the following the invention will be explained in more detail with reference to a non-limiting embodiment, which is illustrated in the drawing. In this shows schematically:

    6 shows a side sectional view of a vehicle headlight with a light source module according to FIG. 1; and
    7 is a perspective view obliquely from the front of a vehicle headlamp with a light source module according to FIG. 4.
    For reasons of clarity, the same elements in the various figures are designated by the same reference numerals
    Fig. 1 shows a first variant of a light source module 1 according to the invention, wherein a laser light source 3 and a spaced-apart light-emitting element 4, which is held in an optical element 9, are arranged on a carrier element 5. The laser light source 3 is, for example, a semiconductor laser in the form of a laser diode or a light source array with a plurality of laser diodes, including the necessary control electronics and cabling. When providing a plurality of laser light sources, these may be color-coordinated, for example.
    The carrier element 5 is made of a heat-conducting material of known type (for example as a heat sink, comprising a heat pipe), thus dissipating the heat produced during operation of the laser light source 3 and the light element 4. For example, the support member 5 may be in " aluminum " or realized as a heat pipe comprehensive heat sink known type. Also possible are various metals, metallic alloys or anthracite or. graphitic polymers. Also possible is a variant in which the carrier element 5 is formed from glass material and contains embedded metal strips (for example copper) for heat conduction.
    To support 4 cooling fins 17 are provided on the underside of the support member 5 in the vicinity of the luminous element. The support element 5 can be made in part of transparent material having irregularities such as microstructures, roughening or scattering body in its interior. As a result, light which leaves the laser light source 3 or the luminous element 4 is mirrored and scattered and thus made visible from the outside, which can be used as a design element.
    For heat dissipation, the laser light source 3 is connected to a cooling element 15. The cooling element 15 serves to additionally dissipate the heat generated during operation of the laser light source 3. The cooling element 15 is arranged on the carrier element 5, or connected thereto. Due to the one-piece design of the cooling element 15 and carrier element 5 optimum heat transfer is given. The cooling element 15 is designed as a heat sink or ventilation device, so either purely for the removal of heat, for example by increasing the surface area by means of cooling fins, or the laser light source 3 is actively fed to a cooling medium, for example by water cooling or a fan.
    The luminous element 4 is designed spherical; It is a phosphorus converter, which is excited by irradiation with laser light for the emission of visible, preferably -10- PI 2417 white light. The luminous element 4 thus donates functionally white light. The spherical design is only one of several variants to make the light-emitting element 4.
    The optical element 9 is made of a predominantly transparent material such as glass or plastic and has a receptacle for the light-emitting element 4, for example a blind hole 10 or a cavity enclosed on all sides by the optical element 9. As a result, the light-emitting element 4 is protected against environmental influences.
    At least one reflecting reflection layer 8 is assigned to the luminous element 4 on a side facing away from the laser light source 3. The reflection layer 8 is designed on the side facing away from the laser light source 3 side of the optical element 9 as a coating. The coating is carried out, for example, by vapor deposition, painting or attaching a separate reflection element. The reflection layer 8 reflects light in the direction of the laser light source 3. Thus, light emitted by the light-emitting element 4 in the direction away from the laser light source is utilized and simultaneously preformed optically. An opaque absorption layer 12 is furthermore applied to the reflection layer 8. This absorption layer 12 serves as a protection to prevent leakage of laser radiation or white light when the reflection layer 8 is irradiated (for example, if it is too thin in some places due to production). In one variant of the invention, only one absorption layer 12 can be provided - in this case, the light is not preformed optically and reflected in the direction of the laser light source 3, but only shielded.
    Depending on the design of the side facing away from the laser light source 3 of the optical element 9 and the reflection layer 8 different light functions can be realized. For example, the side of the optical element 9 facing away from the laser light source 3 (ie, the outer surface) may be designed such that it has at least one focal point and the receptacle configured as a blind hole 10 is arranged so that the luminous element 4 is inserted into the receptacle in one of these Focal points or to be in the vicinity. For this purpose, said outer surface of the optical element 9 (and thus also the reflection layer 8) is preferably designed as a free-form surface. The implementation of a free-form surface is known to the person skilled in the art. -11- PI2417
    In a variant, the outer surface and thus the reflection layer 9 applied thereon are designed such that light above, below and laterally in the vicinity of the luminous element 4 is reflected and thus contributes quasi to an enlargement of the light source or the luminous element 4 - the luminous element 4 is in This variant is virtually surrounded by a ring of light reflected light. The reflection layer 8 thus directs the light reflected by it predominantly on the luminous element.
    A variant of the invention is shown in dashed lines in Fig. 1: On the side of the optical element 9 facing the laser light source 3, an opaque diaphragm device 13 is arranged. This diaphragm device 13 is shown by dashed lines in Fig. 1. In the exemplary embodiment shown, the diaphragm device 13 is arranged in a region below a horizontal plane 200 extending through the luminous element 4. The horizontal plane 200 extends in Fig. 1 normal to the plane and is shown as a dashed line. Of course, other versions are possible depending on the desired light function.
    The diaphragm device 13 can be designed as desired, for example as an opaque coating or as a separate diaphragm, which is adhesively bonded or otherwise applied to the optical element 9 or held mechanically thereon. The diaphragm device 13 allows the generation of a light-dark transition, whereby various light functions such as dipped beam, fog light, etc. can be realized.
    A further variant of the light source module 1 according to the invention is shown in FIG. Therein, instead of the optical element 9 from FIG. 1, a concentrator optical element 7 arranged on the carrier element 5 and connected thereto is provided, which is arranged on the side of the luminous element 4 facing away from the laser light source 3. The light-emitting element 4 is positioned over an unspecified holder, possibly surrounded by an encapsulation that protects the light-emitting element 4 against environmental influences.
    On the one hand, the concentrator optical element 7 serves to shield the luminous element in the mounted state when the light source module 1 is installed, for example, in a vehicle headlight 2, in the main emission direction 100 of the vehicle headlight 2 (see FIGS. 6 or 7). On the side of the concentrator optical element 7 facing the luminous element 4, a reflection layer 8 is further arranged, which directs the light in the direction of the P12417
    Throws back laser light source 3 and preformed optically. For optical preforming, the surface of the concentrator optical element 7 can likewise be embodied such that it has at least one focal point, wherein the luminous element 4 is preferably arranged in this focal point. For this purpose, the surface can be designed as a free-form surface of known type.
    The concentrator optical element 7 can be made, for example, of glass or plastic - possibly then, in addition to the reflective layer 8, an absorption layer 12 is provided in order to prevent radiation through the concentrator optical element 7. Conveniently, the concentrator optical element 7 is made of an opaque material such as metal or plastic, but may also be made in one piece with the carrier element 5 in one embodiment. This variant is shown in FIG. 2.
    FIG. 3 shows a variant of the invention in which a light-guiding element 14 is arranged between the laser light source 3 and the luminous element 4, which is likewise arranged here in an optical element 9. This represents an alternative to the free-jet concept of FIGS. 1 and 2 - the laser light is guided in the light guide element 14 from the laser light source 3 to the light element 4. The light-guiding element 14 consists of a light-conducting material, for example plastic or Plexiglas, and can be shaped as desired, for example tubular, half-tube (in the form of a half-pipe), conical or cylindrical. An embodiment as a funnel-shaped concentrator element, for example made of glass, is possible.
    In or on the light-guiding element 14, irregularities such as microstructures or disruptive bodies can be provided in the element interior, which scatter the laser light and thus make it visible from the outside. By way of example, FIG. 3 shows wave structures 21 on the upper side of the light-guiding element 14. Depending on the intended field of application, the light source module can be used as a design element or as a design element. For example, when using an additional colored, for example, blue, laser light source or LED, which is directed to the microstructures, a blue glow can be generated.
    The Fign. FIGS. 4 and 5 show a perspective view of further variants of the light source module 1 according to the invention. This likewise shows again a luminous element 4 with a laser light source 3 directed thereon. The laser beam 19 between the laser light source 3 and the luminous element 4 is sketched. -13- P12417
    In this variant, the carrier element 5 consists of a support base 50, in which the laser light source 3 is arranged, and an outgoing from the support base 50 support arm 51 with the luminous element 4. The support arm is carried out according to the illustrated embodiment, starting from the support base 50 U-shaped , The light-emitting element 4 is located at the furthest point from the support base 50 on the side of the support arm 51 facing the laser light source 3.
    The luminous element 4 is arranged in a concentrator optical element 7 similar to FIG. 2. In the region around the luminous element 4 (not visible in FIG. 4), the carrier element 5 has an absorber region 18 which has an absorbing or non-reflecting surface. This absorber area 18 serves for safety: If, for reasons not specifically defined, the light source module 1 malfunctions - for example if the luminous element 4 is destroyed or removed or the concentrator element 7 breaks - the laser beam 19 from the laser light source 3 does not strike a reflective one Area or is deflected directly into the environment of the light source module 1 and the vehicle headlamp 2 (see FIGS. 6 and 7), but strikes the absorber area 18 and is absorbed there.
    In addition, further safety precautions are possible: Sensor elements for detecting a malfunction of the laser light source 3 and / or of the carrier element 5 can be arranged on the carrier element 5. Malfunctions are, for example, defects of the laser light source 3 or of the luminous element 4 described above or a fracture of the carrier element 5 due to mechanical action. In the case of a detected malfunction then a shutdown of the laser light source 3 can take place. Marriage records of the sensor elements must therefore be evaluated accordingly or fed into the vehicle safety system.
    Accordingly, said sensor elements may be, for example, an optical sensor for detecting a deviation of the laser light emitted by the laser light source 3 from the proper beam direction about an optical sensor for detecting malfunction of the luminous element 4 or a mechanical sensor for detecting a damage of the carrier element 5 and / or of the luminous element 4 and / or of the optical element 9 or of the concentrator optical element 7. By way of example, in FIGS. 4 and 5, an optical sensor 16 for monitoring the laser beam 19 located. The optical sensor 16 may be, for example, a photocell. The optical sensor 16 is positioned behind the concentrator optical element 7 in the embodiment shown so that it is then hit by the laser beam 19 when the concentrator optical element 7 breaks. As mentioned above, a variety of other designs is possible.
    As an additional safety precaution, the light source module 1 can have at least one safety switching device which prevents activation of the light source module 1 or the laser light source 3 of the light source module 1 prior to installation of the light source module 1 in a vehicle headlight 2 or a reflector 6 or reflector adapter of a vehicle headlight 2 , This may be, for example, a contact switch, which releases the commissioning of the laser light source 3 only in the correct position in the vehicle headlight 2 or in the reflector 6 of a vehicle headlight Another possibility is a coding resistor or a bridge which in the harness or in the lighting unit can be integrated (mechanical and / or electronic) and the commissioning releases only when the vehicle headlight 2 or the light module 1 are installed in the vehicle. Such safety switching devices are not shown in the figures.
    6 shows a sectional view of a light source module 1 according to the invention, which is arranged in a vehicle headlight 2. This is the light source module 1 according to FIG. 1. The vehicle headlight 2 has a reflector 6, into which the light source module 1 can be introduced. The light source module 1 is designed so that in the mounted state, the luminous element 4 is arranged in a focal point of the reflector 6. This makes it possible to ensure optimal utilization of the light emitted by the luminous element 4. In the illustrated embodiment, the light source module 1 is mounted so that the laser light source 3 associated cooling element 15 is disposed outside of the reflector 6. Since the cooling element 15 is thermally conductively connected to the carrier element 5, thereby ensuring optimum dissipation of heat from the reflector 6 out.
    As can be seen in FIG. 6, the light-impermeable reflection layer 8 of the optical element 9 ensures that no light is emitted in the main emission direction 100 of the vehicle headlight 2 and that the laser light can not escape in this direction either. This is also ensured if the light-emitting element 4 is no longer in place. In FIG. 6 it can be seen that in the main emission direction 100 of the vehicle headlight 2 light P12417 is emitted both directly from the light-emitting element 4 via the reflector 6 ("A" in FIG. 6) and light emitted by the light-emitting element 4 via the reflection layer 8 of the optical element 9 to the reflector 6 of the vehicle headlamp he s 2 is deflected ("B" in Fig. 6).
    Another variant of a built in a vehicle headlamp 2 LichtqueUenmo-module 1 according to the embodiment in Fig. 4 is shown in a perspective view in Fig. 7. Therein, the light source module 1 is arranged in a reflector 6, wherein next to the light source module 1 design elements 20 are provided.
    The light source module 1 is introduced in both illustrated variants along the main axis 300 (shown only in FIG. 6) of the reflector 6 and anchored with means for releasable mounting - this may be, for example, locking elements, which cooperate with corresponding locking receptacles in the reflector 6. The means for detachable mounting of the light source module 1 are preferably arranged on the carrier element 5. From the prior art, a variety of such solutions are known, which are therefore not detailed here.
    In order to ensure that the optimum positioning of the module or its luminous element 4 is ensured during installation or when changing the light source module 1, the light source module 1 and / or the laser light source 3 reference means for referencing the light source module 1 and / or the laser light source 3 in Vehicle headlight 2 and in the reflector 6 on.
    The reference means can be designed differently - for example, according to a first variant, they can be guide devices which interact with corresponding guide receiving devices in the vehicle headlight 2 or in its reflector 6 or reflector adapter. For this purpose, in the opening through which the light source module 1 is introduced into the vehicle headlight 2, rails may be provided which cooperate with corresponding slots on the light source module 1 and this until e.g. lead to a stop. Such solutions are known in the art and therefore not elaborated here
    In one variant, the reference means are embodied as a reference plane embodied on the laser light source 3 and / or the support element 4 with at least three support surfaces which interact with corresponding support surface receptacles on the vehicle headlight 1, in particular on the reflector 6 of a vehicle headlight 1. In another variant, the reference means are designed as at least one dowel pin and at least one dowel hole, the dowel pin being arranged on the laser light source 3 and / or the carrier element 5 and the dowel hole being located on the vehicle headlamp 2, or vice versa Pass holes and pins are provided on the vehicle headlight, which interact with corresponding complementary holes and pins on the laser light source 3 and / or the carrier element 5.
