    Lighting device for a vehicle headlight
    The invention relates to a lighting device for a vehicle headlight, the lighting device comprising: at least one LED light source, at least one light-shaping optical body associated with the at least one LED light source, at least one LED light source support on which the at least one LED light source is mounted is.
    Furthermore, the invention relates to a vehicle headlight with at least one such lighting device.
    In vehicle headlamp design, LED light sources consisting of one or more light-emitting diodes are increasingly used to produce one (or more) main light distribution (s), such as high beam distribution, dimmed light distributions, e.g. Dipped beam, etc. used. Usually, the light from one or more LED light sources is transmitted via one or more optical bodies, e.g. via one or more reflectors, attachment optics in the form of light-guiding bodies, etc., directly or via further optic bodies, into an area in front of the motor vehicle into which the vehicle headlamp is installed, and these illuminate / illuminate the area in front of the vehicle.
    In order to be able to realize a law-compliant light distribution, it is important that the optical body and associated light source (s) are correctly positioned relative to each other. Especially with the use of LED light sources, this topic is even more important, since relatively small deviations from the desired position can already lead to unwanted and / or impermissible effects in the photograph. 2/31 -2- P13158 Usually, the LED light source (s) is / are located on a heat sink. The LED light source (s) sits or sit on a support, which is usually in the form of an LED board, and the support in turn is arranged on the heat sink, for example glued to it. The associated optical body is positioned accordingly and then fixed to the heat sink or with respect to the heat sink, usually screwed with this or with another fixed component of the lighting device.
    However, it has frequently been shown that it can come to a distortion of the optic body by the fastening process, in particular by tightening the optic body and the forces occurring or it comes generally in the attachment process to an unintentional adjustment of the optic body from the optimum position. This has a detrimental effect on the photograph obtained, partly with the result that the photograph no longer meets the legal requirements.
    In particular, this raises the problem of warping the optic body when the optic body is designed as a reflector, which are often made thin-walled and are correspondingly prone to distortion.
    It is an object to provide a lighting device for motor vehicle headlights, in which the above-mentioned problems are eliminated and an exact adjustment of the position of the at least one LED light source with respect to the at least one optical body can be realized.
    This object is achieved with an illumination device mentioned in the introduction in that, according to the invention, positioning means for positioning the at least one LED light source carrier are provided on the optical body, further positioning means are provided for the subsequent positioning of a heat sink on the optical body, and further wherein a fixing element is provided, which is fastened to the optical body such that in the fastened state, the fixing member presses the heat sink against the LED light source carrier so that it is fixed in position on the optical body.
    With the fixing of the heat sink according to the invention is clamped attached to the optical body. The clamping force presses the heat sink against the LED light source carrier and this against the optical body, so that the carrier is permanently fixed in its set position.
    By clamping fixing with the fixing screwing the carrier and / or heat sink can be avoided on the optical body, so that the optical body, in particular a reflector, such as a free-form reflector, can be entzugsweise connected to the or the LED light sources.
    The LED light source carrier is to equip before the installation of the lighting device according to exactly the or the LED light sources, as well as the optical body is to be manufactured according to accurate. As a result, however, the lighting device presented according to the invention can also be easily manufactured on the assembly line, since adjusting the optical body with respect to the LED light source (s) on the assembly line is no longer necessary and therefore the lighting device can be manufactured quickly and efficiently.
    Another advantage is that the heat sink falls out of the tolerance chain in the lighting device according to the invention.
    In an advantageous embodiment of the invention it is provided that at least two, preferably exactly two domes are arranged on the optical body, it being particularly advantageous if the dome extending parallel to each other extending from the optical body. 4/31 -4- P13158

    Preferably, this is the positioning between the two retaining springs, most conveniently located in the middle between the positioning pins.
    With this pin, the carrier in the Y direction, i. horizontally and normally in the X direction.
    Subsequently, the heat sink is arranged on the optical body with prepositioned LED light source carrier.
    Preferably, the positioning means for the heat sink comprise at least one, preferably two Positionierausnehmungen and / or positioning ribs, which are arranged on the optical body, preferably formed integrally with this / are.

It is advantageous if the heat sink on a side facing the optical body at least one, preferably exactly two corresponding to the positioning recesses and / or positioning ribs Positionierausrippen and / or Positionierausnehmungen.
    The heat sink is inserted with its ribs in the Positionierausnehmungen so that they surround the ribs laterally, and so the position of the heat sink is defined transversely to the longitudinal extent of the ribs.
    Alternatively or additionally, it can also be provided that the positioning means for the heat sink are formed by the dome arranged on the optical body.
    In any case, regardless of whether or not the domes serve as positioning means for the heat sink, the fixing means has one of the number of domes corresponding, preferably exactly two elastic clip portions.
    The elastic clip portions are in particular or in any case in the direction of the longitudinal extent of the dome, that is formed elastically deformable in the Z direction. 6/31 -6- PI3158

    Furthermore, it is advantageous that the heat sink has at least one, preferably exactly two stop pins, which at least one stop pin is preferably formed integrally with the heat sink, wherein the at least one stop pin limits the Aufschiebbewegung the fixing on the heat sink.
    Finally, it is also still favorable if the heat sink and the fixing element have holding means which prevent a release of the fixing element from the heat sink in the pushed-on state.

    In a specific embodiment, it is provided that the holding means have at least one, preferably beveled pin and at least one corresponding recess.
    The recess is preferably provided on the heat sink, the pin on the fixing means; due to the bevel, the pin can be pushed into the recess, then hooked there 7/31 -7- P13158, so that the fixing element against the Aufschieberichtung can not be pulled down from the heat sink.

    FIG. 12 shows a section along the line A-A from FIG. 11.
    Figure 1 shows the invention relevant components of a lighting device 1 for a vehicle headlight. In the illustrated embodiment, the lighting device 1 comprises an LED light source 2 which, in the embodiment shown, consists of a plurality of LEDs (light-emitting diodes). Furthermore, the lighting device 1 comprises a light-shaping optical body 3, which is associated with the LED light source 2. The LED light source 2 couples light via a coupling point 3d in the optical body 3 a.
    In the specific example, the optical body 3 is a reflector 3, the coupling point 3d is formed as an opening in the reflector, via which the LED light source 2 can emit their light on the reflective surface of the reflector.
    In general, that is, irrespective of the type of optical body, one or more LED light sources can be provided, wherein each LED light source can have one or more LEDs. Preferably, some or all of the LED light sources are independently controllable, i. can be switched on and off and possibly also dimmed. Likewise, it may also be advantageous if individual or each LED of an LED light source can be controlled independently. 9/31 -9- P13158
    Furthermore, the lighting device comprises an LED light source carrier 4, on which the LED light source 2 is mounted. The carrier 4 is usually an LED board.
    Finally, the lighting device 1 summarizes still a heat sink 5 for dissipating the heat generated by the LED light source 2 and a fixing means 6, whose function will be described in more detail below.
    In an assembly of the lighting device 1, the LED board 4 is initially positioned on the optical body 3 and temporarily fixed and then the heat sink 5 is positioned on the optical body 3 and the LED platinum 4 and fixed with the fixing means 6.
    In the embodiment shown, the optic body 3 has two preferably parallel webs or ribs 60, on which the carrier 4 rests.
    For this purpose, positioning means 3a, 3b, 3c for positioning the LED light source carrier 4 are initially provided on the optical body 3.
    The positioning means on the optical body 3 in this case comprise two domes 3a, which are integrally formed with the optical body 3 and projecting from this parallel to each other. The domes 3a are in this case-generally, that is to say independent of the specific embodiment of the optic body-preferably in the region of the "coupling-in point". arranged, in the specific example, ie in the region of the opening 3d of the reflector 3. It is optimal if the dome 3a are arranged symmetrically about the coupling point.
    Furthermore, the positioning means comprise two retaining springs 3b, which in turn are preferably formed integrally with the optical body 3.
    Figures 2 and 3 show the carrier 4 before placing, this is placed along the dome 3a in the direction of the optical body 3 on this. FIG. 4 shows the carrier 4 in the state already placed and positioned on the optical body 3. In this case, after placing the LED light source carrier 4 on the optical body 3, the carrier 4 is pressed by the retaining springs 3b in the direction of the dome 3a and thus temporarily positioned. 10/31 -10- P13158
    In order to set the carrier 4 on the optical body 3, it is provided that the LED light source carrier 4 has two - on one side preferably open - recesses 4a, which surround the associated dome 3a - in the example shown on three sides. Via the recesses 4a, the LED light source carrier 4 can be positioned in the X direction normal to the orientation Z of the domes 3a.
    The recesses 4a are thus arranged and configured in principle such that the LED light source carrier 4 can be threaded with the recesses 4a in the domes 3a and subsequently moved in the direction of the optic body 3, where the support 4 is finally pressed into the retaining springs 3b , so that they press the carrier with the recesses 4a against the dome 3a (see for example Figure 3).
    The carrier 4 is thus in the X-direction (for the coordinates see Figure 1), i. is at least temporarily positioned and held in the light exit direction in its position on the optical body.
    Furthermore, the positioning means further comprise a positioning pin 3c, which is arranged on the optical body 3, preferably formed integrally with the optical body 3, and the LED light source carrier 4 has a corresponding recess 4b, by means of which the LED light source carrier 4 in the Y-direction can be positioned on the optical body 3. "Positioned " means in each case that in the respective direction (X, Y, ...), the position of the carrier, etc. with the respective component (dome, pin, retaining spring) is set.
    Preferably, the positioning pin 3c between the two retaining springs 3b, most conveniently located in the middle between the positioning pin 3c.
    With this pin, the carrier 4 can thus be in the Y direction, i. horizontally and normally in the X direction.
    In a next step, the heat sink 5 is positioned on the optical body 3, for which purpose positioning means 31 for the heat sink 5 are provided on the optical body 3. 11/31 -11- PI3158
    The positioning means for the heat sink 5 are formed in the embodiment shown as two positioning recesses 31 (see, for example, Figures 1 and 2), which positioning recesses 31 are arranged on the optical body 3, preferably formed integrally therewith. Advantageously, the two Positionierausnehmungen 31 parallel to each other.
    The cooling body 5 has, on a side facing the optical body 5, two positioning ribs 30 corresponding to the positioning recesses 31, see e.g. FIG. 1
    The heat sink is inserted with its positioning ribs 30 in the Positionierausnehmungen 31 so that they surround the ribs 30 laterally, and so the position of the heat sink is defined transversely to the longitudinal extent of the ribs.
    In addition, the heat sink 5 has two dome openings 5 a, through which the dome 3 a are inserted during the application of the heat sink 5. In this case, the dome 3a on two casserole portions 3a ', whose function will be discussed below, and the dome openings 5a are sufficiently large dimensions, so that the dome 3a together with their casserole portions 3a' can be pushed through them. The casserole portions 3a 'are preferably integrally formed with their respective dome 3a.
    In particular, it is favorable if, in the completely pushed-through state of the dome 3a, the run-on portions 3a 'are at a distance above the respective dome opening 5a.
    For fixing the heat sink 5 and thus the LED light source carrier 4 to the optical body 3, a fixing element 6 is finally provided. This fixing element 6 can be fastened to the optical body 3 such that in the fastened state, the fixing element 6 presses the heat sink 5 against the LED light source carrier 4, so that it is fixed in its position on the optical body 3.
    In this case, the fixing element 6 holds the heat sink 5 by clamping on the optical body 3. For this purpose, the fixing element 6 has one or more return areas, which exert a clamping force when applied, in particular a sliding of the fixing element 6 on the optical body 3 and heat sink 5. This clamping force presses the heat sink 5 against the LED light source carrier 4 and this against the optical body 3, so that the 12/31 -12- P13158
    Carrier 4 is permanently fixed in its set as described above, temporary position.
    By clamping fixing with the fixing element 6 screwing the carrier and / or heat sink to the optical body can be avoided, so that the optical body, in particular a reflector, such as a free-form reflector, can be preferably connected to the or the LED light sources.
    In this case, the LED light source carrier 4 is to be equipped correspondingly exactly with the LED light source or sources 2 prior to the assembly of the lighting device 1, and the optical body 3 is to be manufactured correspondingly accurately. As a result, however, the lighting device presented according to the invention can also be easily manufactured on the assembly line, since adjusting the optical body with respect to the LED light source (s) on the assembly line is no longer necessary and therefore the lighting device can be manufactured quickly and efficiently.
    Another advantage is that the heat sink falls out of the tolerance chain in the lighting device according to the invention.
    The above-mentioned return areas of the fixing element 6 - which are one, two or more return areas, the number preferably corresponds to the number of domes 3a - are formed in the embodiment shown as (corresponding to the number of 2 domes) exactly two elastic clip portions 6a Each clip section 6a represents a reset area.
    The elastic clip portion 6a are in particular or in any case in the direction of the longitudinal extent of the dome, that is formed elastically deformable in the Z direction.
    As already mentioned above, each dome 3 a has, in a region facing away from the optical body 3, a run-on section 3 a 'for in each case one elastic clip section 6 a of the fixing element 6.
    Figure 6 and 8 shows the fixing element 6 in a patch on the heat sink 5, but not yet pushed on state. As can be seen in FIG. 7, the fixing element 13/31 -13-P13158 has 6 openings 6a 'for pushing through the dome 3 together with run-on surfaces 3a. The clip portions 6a are slotted so as to allow the fixation member 6 to be displaced onto the heat sink 5 with the domes 3a inserted into the corresponding slots 6a " (Figure 6) are pushed.
    When pushed (Figure 7 and 9) of the fixing member 6 on the optical body 3 and the heat sink 5 in a direction normal to the orientation Z of the dome 3a - specifically in the negative X direction - the elastic clip portions 6a in the direction of the optical body 3 pressed.
    In this way, the LED light source carrier 4 and the heat sink are permanently fixed to the optical body by simply pushing the fixing element 6 from the front onto the optical body 3 with exposed heat sink 5.
    When pushing the fixing element 6, preferably from the front as shown, opposite to the light exit direction, as shown in FIGS. 7 and 9, the elastic portions 6a of the fixing element 6 come under the casserole portions 3a, i. between casserole portion 3a and heat sink, wherein the elastic portions 6a are pressed against the heat sink 5 by the casserole portions 3a '.
    By the restoring force of the elastic portions 6a thus the components optics body 3 (via the dome 3a), heat sink 5 and LED light source carrier 4 are pressed together and thus fixed without screws must be mounted in the optical body 3.
    FIG. 10 shows once again the situation in the region of an elastic section 6a after the fixing element 6 has been pushed onto the heat sink 5.
    The heat sink 5 additionally has two stop pins 5b, which are preferably formed integrally with the heat sink 5b, wherein the stop pin 5b delimit the sliding movement of the fixing element 6 onto the heat sink 5.
    With the stop pin 5b further movement of the fixing element 6verhindert, the stop pin 5b thus forms a stop for the fixing element 6 so that it remains in a defined X position to the other components. 14/31 -14- P13158
    Reference will now be made to FIGS. 11 and 12, wherein, in particular in FIG. 12, which shows a section along the line A - A through the lighting device 1, it can be seen that the heat sink 5 and the fixing element 6 hold means 5 ', 6'. have, which prevents loosening of the fixing element 6 of the heat sink 5 in the pushed-NEM state.
    Thus, it can be ensured that a manual release of the fixing element 6 from the heat sink 5 is no longer possible and possibly only possible with a tool.
    In the specific embodiment of the figures, it is provided that the holding means have at least one, preferably bevelled pin 6 'and at least one corresponding recess 5'.
    The recess 5 'is preferably provided on the heat sink 5, the pin 6' on the fixing means; by the bevel, the pin 6 'in the recess 5' push, then hooked there, so that the fixing against the Aufschieberichtung can not be pulled down by the heat sink.
    In a particularly advantageous embodiment, as shown in the figures, the fixing means 6 is designed as a design panel, which is formed for example of plastic or sheet metal.
    On the one hand serves in this case, the fixing means for fixing the heat sink and the LED light source carrier, on the other hand can be shielded with the fixing then also areas of the lighting device, which are not visually accessible.
    For example, can be covered with the design panel 6 of the heat sink 5, so that it is not visible from the outside in the installed state of the lighting device.
    With the present invention, it is thus possible to attach an LED light source carrier to an optical body, in particular a reflector, for example a free-form reflector without screws, so that no torque acts on the optical body. It is only 15/31 -15- P13158 applied a tensile force in the region of the dome, i. it is only introduced via the dome, a tensile force in the optic body. 16/31
