    description
    The invention relates to an LED light source module for a LED motor vehicle headlight, in particular for an LED motor vehicle headlight for generating a dynamic light distribution, wherein the LED light source module has at least one LED light source, wherein the at least one LED light source of at least one light emitting diode and wherein the at least one light-emitting diode of the at least one LED light source couples light into an associated primary optic element, the injected light emerges at least partially from a light exit surface of the primary optic element, and wherein the LED light source module has a secondary optic the light emerging from the at least one light exit surface of the at least one primary optic element - in the state of the headlamp installed in a vehicle - is imaged as a light image in a region located in front of the vehicle.
    The invention further relates to a headlamp with such an LED light source module and a corresponding headlamp system.
    In motor vehicle construction, light-emitting diodes are increasingly being used for the realization of main headlamp functions, such as e.g. for generating low beam and / or high beam but also of other light functions, such as motorway light, bad weather and daytime running lights.
    Furthermore, headlight LED light sources are also particularly well suited for special applications, such as object lighting, where only certain LED light sources are visible or emit light, while the remaining LED light sources emit no light. In object lighting, for example, objects on the roadside, such as pedestrians, but also traffic signs, may be illuminated with light, e.g. with infrared light, illuminated, and these objects can then be captured with an infrared camera. Of course, visible light, such as traffic sign lighting can be used.
    Conversely, of course, it may also be possible to change precisely from light distribution, such as a far-light distribution in the event of oncoming traffic, those areas of light distribution, PI2038
    which would lead to dazzling oncoming traffic, hide, so that no glare occurs.
    The above tasks can be realized by selective activation or in the latter case by selectively deactivating certain LED light sources.
    For the selection of certain LED light sources, cs currently provides electronic solutions in which only certain LED light sources are activated or deactivated so that only the desired LED light sources emit light onto the street. This solution offers a high degree of flexibility, as basically any LED light sources are activated.
    Other solutions show apertures, which can be brought to Lichtabschattung certain LED light sources in a corresponding position.
    From the Austrian application AT 508604 of the Applicant a headlight with the aforementioned LED light source modules is known, with which a dynamic light distribution can be generated, which can be adapted to different traffic situations, etc. in ferry operation.
    In particular, such a headlamp can be realized with conventionally available LED light sources.
    With such a headlamp, individual light functions, such as low beam, high beam, cornering light, etc., can be implemented without moving parts by means of static light technology by dividing the luminous area into segments which can be switched separately. The light originating from the LEDs is projected onto the roadway via the individual primary optics elements which form the individual segments of the light exit surfaces and the associated secondary optics as segmented light distribution.
    However, as the distance between the luminous segments of the primary optics from the optical axis of the associated secondary optics becomes problematic, the distortion error of the secondary optics (projection lens) becomes such that it is in an outer portion of the light image which is from the segment farthest from the optical axis (s) of the primary optic elements is formed, to a distortion of the
    Photograph comes, in particular to a pillow-shaped distortion, which is primarily above the cut-off.
    An optical correction of the secondary optics is technically feasible, but not economically viable.
    It is an object of the invention to the above problem in an economically meaningful way.
    This object is achieved with an LED light source module mentioned in the introduction in that, according to the invention, a diaphragm arrangement is provided between the at least one light exit surface of the at least one primary optic element and the secondary optics, which diaphragm arrangement has at least one optically effective diaphragm edge, which is arranged and / or extends in such a way in that unwanted distortions occurring in an upper and / or lower region of the light image are at least partially hidden in the light image.
    By using a diaphragm arrangement distortions that occur anyway at the edge of the light image can be hidden in a simple and cost-effective manner without adversely affecting the remaining light image.
    The above-mentioned problem occurs in particular, as already discussed above, when the LED light source module has two or more LED light sources, wherein an LED light source consists of at least one light emitting diode, and wherein the light emitting diodes of each LED light source light in one coupled in each case the light source associated primary optic element, wherein the coupled light at least partially exits the light exit surface of the associated primary optics element again, and wherein the secondary optics generated by the light exit surfaces of the primary optics elements light segments installed in a vehicle state of the headlamp - lying in front of the vehicle Area pictures.
    By using a diaphragm arrangement, the problems occurring can be optimally eliminated, in particular in such an arrangement.
    All primary optics elements associated with a secondary optics form the so-called "primary optics", the primary optic elements are preferably connected to one another, and as a rule even formed in one piece. This primary optic has an overall light exit surface formed by the individual light exit segments of the primary optic elements.
    In a specific variant of the invention, it is provided that the total light exit surface formed by the light surface (s) of the one or more primary optic elements has a defined height and width extension, for example in the form of a rectangle, and wherein the focal point of the secondary optic element is in a lateral edge region Total light exit surface is located, and wherein the at least one edge has a profile / contour in which the edge to the focal point has a greater normal distance than to a horizontal plane through the focal point of the Sekundäroptikelementes in the focal point opposite edge region of the total light exit surface.
    In the edge further away from the focal point, the diaphragm edge therefore has a smaller (normal) distance than in the region of the focal point (which is in the other edge region); for different modules, the focal point may be at different locations, but always in an edge area.
    The focal point of the secondary optics lies in the plane of the light exit surfaces of the primary optics element or T. primary optics, where the optical axis of secondary optics pierces the plane "."
    It is expedient if the normal distance of the diaphragm edge to the focal point of the secondary optical element represents the greatest distance of the diaphragm edge to the horizontal plane, and that the distance to the horizontal plane decreases towards the edge region remote from the focal point W 'further.
    The measures described above ensure that light is adequately isolated in the areas from which the distortions originate, while light from the areas with little or no distortion in the photograph is little or no shielding. PI 2038
    In particular, it is advantageous if the normal distance of the diaphragm edge to the focal point of the secondary optical element represents the greatest distance of the diaphragm edge to the horizontal plane, and that preferably above the edge region having the focal point the normal distance to the horizontal plane remains the same as the normal distance of the diaphragm edge to the focus.
    In order to be able to seal off distortions in the photograph both above and below the bright-dark boundary, it is further provided with advantage that the diaphragm arrangement has two optically effective diaphragm edges, an upper diaphragm edge and a lower diaphragm edge, wherein the upper diaphragm edge above a horizontal plane through the optical axis of the secondary optics runs, and the lower edge below this level.
    The diaphragm arrangement consists of a diaphragm or two diaphragms which have or have at least one optically effective diaphragm edge, but preferably only one diaphragm component, ie exactly one diaphragm, with one or two diaphragm edges, is provided.
    A compact and stable arrangement results when the shutter assembly, e.g. the one or both panels, integrally formed with a holder for the primary optics or attached to this holder.
    Furthermore, it can also be provided that the diaphragm arrangement, e.g. the one or both diaphragms, is formed from an at least partially transparent material in the optical region, wherein, for example, the diaphragm arrangement or the at least one diaphragm is coated with the semi-transparent material.
    The diaphragm arrangement or the at least one diaphragm is not complete in this case, i. not designed to be 100% light-shielding, but allows some of the light to pass through. In this way, softer spills in the light distribution, primarily at the cut-off line, can be realized.
    For example, an aperture formed of a transparent material on the surface is coated with e.g. Metal coated. Depending on the thickness of the layer seems this is more or less translucent, so partially translucent. For example, this coating can be designed in such a way that in the region of the diaphragm edge it is completely translucent

    In an embodiment which is simple to realize and which requires little space and gives optically very good results, it is provided that the at least one diaphragm is planar or that the at least one diaphragm edge extends in a vertical plane which is preferably parallel to the total light exit surface of the primary optical elements. lies.
    The at least one aperture is flat and is normal to the light exit direction in the beam path.
    Visually even slightly better results can usually be achieved if the at least one diaphragm or the at least one diaphragm edge is curved in the horizontal direction, wherein the curvature preferably corresponds substantially to the field curvature of the secondary optical element or this image field follows curvature.
    The curvature of the at least one diaphragm edge (in a horizontal plane) follows the field curvature of the secondary optics, or the diaphragm (at least one blade edge) is curved away from the light exit surface of the primary optic element.
    However, this variant is more complex in production and requires more space.
    In addition, it is advantageously provided that the Blcndenkante or the projection of the at least one aperture edge in a vertical plane has a curved course.
    An aperture edge thus consists of a projection in the vertical plane of one or more curved curve sections.
    However, it can also be provided that the diaphragm edge or the projection of the at least one diaphragm edge into a vertical plane consists of one or more rectilinear Ab-section (s).
    It can be provided that the transition between two rectilinear sections or between two curved curve sections discontinuously, e.g. in the form of an edge.

    Likewise, it can be provided that the diaphragm edge or the projection of the at least one diaphragm edge has a continuous or a discontinuous course.
    It has been found that optimal results are usually obtained by placing the beam stop at a short distance before the primary optic, e.g. in a specific variant between about 10mm to 20 mm away from the primary optics. If it is necessary due to space constraints to arrange the radiation diaphragm directly on the primary optics (that is to say, on the light exit surface thereof), disruptive spikes occur in the light distribution. With a discontinuous, "ragged " the iris edge (s) can be minimized these peaks in the photograph.
    Furthermore, it is provided that, if exactly two diaphragm edges are present, the upper edge has a smaller normal distance, preferably along the entire horizontal extension, to a horizontal plane through the focal point of the secondary optical element than the lower edge.
    In this way, for example, a high beam or a Teilfem light can be optimally generated. The position of the plane EH basically depends on which light distribution is to be generated, so the invention is not limited to the fact that the plane EH is above the plane of symmetry. Usually, the light exit surface of a primary optics in the vertical and horizontal directions is symmetrical. The upper and the lower diaphragm edge have a horizontal plane that halves this light exit surface at approximately the same distance (at the same position along the plane in the horizontal direction); in some variants, the upper and lower edges are even mirrored around this plane, ie have identical distances.
    To produce a desired light image, the horizontal plane lies through the focal point of the secondary optics above this plane of symmetry, which is why the different distances of the two diaphragm edges to the horizontal plane result from the focal point of the secondary optics. Γ12 (138 «« «ft« »» ♦ • · • »
    The light image is trimmed correspondingly less in the lower area than in the upper area (the lower area results from projection of the upper area of the light exit area by means of secondary optics and vice versa).
    In principle, the upper and lower edges can have any desired shape, in particular any desired shape, with respect to the specific profile, i. Any symmetries between the upper and lower edge are not absolutely necessary.
    However, it may be advantageous if it is provided with exactly two aperture edges that the upper edge and the lower edge have a mirrored with respect to a horizontal plane of symmetry. That the top edge, mirrored around the plane of symmetry, gives the bottom edge.
    The horizontal plane through the focal point of secondary optics lies above this horizontal plane of symmetry through the total light exit surface (see above).
    Due to the segmentation of the total light exit surface, inhomogeneities, such as, for example, in the light distribution, especially in the apron area, occur. Fraying, banding, or staining that interfere with the projection on the ground / road surface. To avoid this or to reduce these effects, it can be provided that the light exit surfaces of the primary optics elements of an LED light source module are connected to each other by means of a translucent material such that light coupled into the primary optics elements enter the translucent material and via a light exit surface of the translucent material Material can escape from this again.
    Through the connection of the individual primary optics elements, whose light exit surfaces indeed produce the segments in the light image, with a light-transmissive material, it is achieved that the inhomogeneities in the light image as a result of the banding blurred into each other, so that the disturbing effects are reduced or completely eliminated in the photograph. PI2038 * * • «« «t ·« · · 9 · .. ·· .. ·· .. ·:
    In a specific variant of the invention, it is provided that the light exit surfaces of the primary optic elements lie in a common area, and that the light exit surface of the translucent material also lies in the common area of the light exit surfaces of the primary optic elements.
    This common surface is formed either as a plane or curved according to the field curvature of the secondary optics.
    Part of the light entering a primary optic element is no longer emitted via the light exit surface of the primary optic element itself, but enters the light-transmissive material and exits via its light exit surface. As a result, a part of the light which enters the primary optics element mixes and reduces or eliminates the inhomogeneities in the light image. The light emerging from the translucent material thus contributes to the distribution of light.
    To be particularly favorable in order to reduce / eliminate the inhomogeneities, it has been found that the light exit surfaces of the primary optic elements are connected to one another in an upper and / or lower region.
    Preferably, the primary optic elements are in any case connected to one another in the upper region. The terms "top" and "below" refer to the installed state of the module / headlamp.
    This upper area is imaged via the secondary optics in the light image below the cut-off line, where the unwanted inhomogeneities occur first or most.
    The compound in the lower region is of less importance optically and has advantages, especially in mechanical terms, in order to increase the stability of the entire element formed by the individual primary optic elements.
    In a specific variant of an LED light source module, it is provided that at least one substantially horizontally extending connecting web, which differs from the light transmission Γ12038 • · • »Γ12038 • · •»
    Is formed, is provided, which connects the primary optic elements in the upper and / or lower region of their light exit surfaces together.
    In particular, exactly two substantially horizontally extending connecting webs, which are formed from the translucent material, are provided which connect the primary optics elements in the upper and lower regions of their light exit surfaces, the upper web being of optical and mechanical importance on the one hand. while the lower bridge is mainly of mechanical importance.
    Preferably, the at least one connecting web is formed cinstückig with the light exit surfaces of the primary optic elements or with the primary optic elements, i. the individual primary optic elements and the connecting bridge or links form a single element, the so-called primary optic.
    Irrespective of whether or not the webs and primary optic elements are integrally connected to each other, it is advantageous if the light exit surfaces of the primary optic elements and those of the at least one connecting web form a common light exit surface, i. that they lie in a common plane and preferably also without interruption, i. without a gap, etc., are interconnected.
    In order to achieve optimum optical effects, it is provided that the at least one connecting web extends in the vertical direction upwards / downwards in each case beyond a certain, defined height beyond the light exit surfaces of the primary optics elements.
    In the above sense, it is also when the at least one connecting web in the horizontal direction, extends laterally over a certain length beyond the light exit surfaces of the primary optics addition.
    Furthermore, it is expedient if the at least one connecting web extends in the horizontal direction to the rear in the direction of the light sources and is connected to the primary optics over a certain extent. -11 - PI2038 • * * *
    Diu interpretation of the or the connecting webs, in particular the extension of the / the Verbindungsstcge (s) to the rear has on the one hand effects on the homogeneity of the light image, which on the other hand with a reduction of the maximum in the light distribution is received, that is, the more homogeneous the light image is selected more strongly the maximum is reduced.
    Depending on the desired effects, it is therefore provided that the extension of the at least one connecting web downwards / upwards and / or the outward extension of the at least one connecting web laterally beyond the light exit surfaces of the primary optics and / or the extension of the at least one connecting web in the horizontal direction to the rear, in particular, the extension, via which the at least one connecting web is connected to the primary optical elements, is / are selected such that the desired degree with respect to the homogeneity of the photoimage and the desired degree of reduction of the maximum in the light distribution result.
    As described below, several LED light source modules are used in a headlight. Basically, it is provided that they have, as far as possible, an identical structure, in particular also that they have identical primary optic elements or primary optics (= primary optics connected to one or two webs). In principle, however, it can also be provided for optical reasons that the modules, in particular the primary optics, and in particular the design of the at least one connecting webs, differ from one another, so that an optimal adaptation of the desired photograph can take place.
    Light from the LEDs propagates in the primary optic elements as a result of total internal reflection. To allow a sufficient amount of light to enter the translucent areas, i. into which or the connecting webs can occur, it is therefore advantageous, as described above, if they are connected to the primary optics over a certain extent - in the sense of contacting one another, preferably being connected to one another, in particular cin-piece.
    It may also be optically favorable if the at least one, in particular the upper, connecting web in the direction of the light coupling points of the primary optic elements is formed, for example wedge-shaped, in a tapering manner. PI2038 • * I · · · I * · · · · · · ··· I fl · · -12-:
    This embodiment brings significant improvements in optical terms in comparison with a cuboid, so not tapered embodiment of the connecting web. This applies in particular, the farther the connecting bridge extends to the rear. In addition, material can be saved by the wedge shape, which leads to a cost reduction.
    In particular, it may be favorable if the primary optic elements widen from their light coupling points to the light exit surfaces, with the primary optic elements expanding more towards the bottom than towards the top.
    The primary optic elements have e.g. a wedge-shaped shape, wherein the element rises more towards the bottom.
    In principle, relatively arbitrary shapes can be used for the light exit surfaces of the primary optic elements. As low it has been found when the light exit surfaces of the primary optic elements are rectangular. Corresponding primary optics are easy to produce and have good optical properties with regard to the superposition of the light distribution segments generated by the primary optics via the secondary optics. With such light exit surfaces can also be generated over the entire height of the light distribution in the horizontal direction, a homogeneous light distribution without gaps in the light image For most applications, it is sufficient if all the light exit surfaces have an identical shape. This has the advantage of simply calculating and manufacturing the headlamp and significantly reduces the cost of the headlamp.
    However, it can also be provided that light exit surfaces of different shapes, e.g. be used with different widths (horizontal extent). For example, certain areas of the light distribution can be generated with narrower light exit surfaces, which results in a finer segmentation of the light image there and smaller or narrower areas can be hidden.
    Furthermore, cs is favorable if the light exit surfaces of the primary optic elements are arranged parallel to one another and with identical orientation. 38 2038 · · · · · · · · · · · · · · · ·. · · · · · · · · · ·

    Due to the parallel and identical alignment can be easily generated in the vertical direction and in a simple manner a law-compliant light image.
    It is particularly advantageous if the light exit surfaces of the primary optic elements of an LED light source module are arranged next to one another horizontally.
    On the one hand, such an arrangement can be realized in practice without particular difficulty, on the other hand so form the light exit surfaces on the secondary optics sharply defined segments in the light image, the superposition then results in the entire light image. By switching off one or more LED light sources, it is possible to optimally hide defined areas in the light image in such an arrangement.
    As already mentioned above, each LED light source module is associated with secondary optics, which image the light segments generated by the light exit surfaces of the primary optics elements-in the vehicle-mounted state of the headlight-in a region located in front of the vehicle.
    The inventive arrangement of the LED light sources in two or more LED light source modules allows a homogeneous light distribution, e.g. a high beam distribution, be generated by corresponding horizontal juxtaposition and / or superimposition of the individual light segments, from which light distribution by switching off one or more LED light sources quite specific areas of the light distribution "hidden", ie. can not be illuminated, for example, to avoid dazzling oncoming traffic.
    For example, the individual light segments can be arranged directly adjacent to one another in the horizontal direction. In order to avoid too abrupt transitions or to see edges in the light distribution, one or more other light segments can additionally be superimposed in such regions of abutting light segments. This also has the advantage that, as discussed later in detail, by fading out e.g. two light segments areas of the light distribution "hidden" or can not be illuminated, which are narrower than a light segment.
    In a concrete form, the light exit surfaces are standing in the vertical direction, with a height greater than the width, are formed, e.g. in the form of rectangles or ellipses etc.
    By this standing shape with greater height and smaller width is illuminated with a light exit surface, a narrow angle range in the horizontal direction, in vertical terms, the entire area for this horizontal angle range can be illuminated with this one light exit surface.
    It is particularly advantageous if adjacent light exit surfaces of the primary optic elements of an LED light source module have a normal distance from one another, which corresponds to the width of a light exit surface, and if preferably a first overall arrangement of the light exit surfaces occupies a first defined position with respect to the optical axis of their secondary optics , and wherein a second / third / fourth-nth overall arrangement with respect to the optical axis of their secondary optics compared to the first overall arrangement by half / single / double / quadruple / ((nl) / 2) times the normal distance is displaced between two adjacent light exit surfaces of an LED light source module.
    This results in an arrangement in which - apart from the horizontal edge regions - by Ausblcnden of zwTei light sources of the entire headlight, a sharp area which corresponds to half the width of a light exit surface, can be hidden.
    In a concrete, proven embodiment of the invention, the distances between light exit surfaces of adjacent primary optics elements are the same for three or more primary optics elements, and preferably all distances between the light exit surfaces of adjacent LED light sources are identical over the entire headlamp.
    This results in a simple structure with identical modules, with which a homogeneous light distribution can be achieved.
    An inventive LED automotive headlamp for generating a dynamic light distribution comprises two or more LED light source modules as described above, wherein preferably the secondary optical elements of the LED light source modules and the PI2038 PI2038
    -15-
    Arrangement of the light exit surfaces of the primary optic elements are matched to one another such that the light segments from the individual LED light source modules are shown offset in the horizontal direction to each other, and wherein the individual LED light sources are controlled separately.
    It is particularly advantageous in such a headlamp if the course of the at least one diaphragm edge is identical in all LED light source modules, in particular that with two diaphragm edges per LED light source module, the upper diaphragm edges have an identical course and / or the lower Aperture edges have an identical course.
    This brings great advantages, in particular with regard to a simple manufacture of the panels, the assembly of the modules and the storage.
    In a specific version, it is provided that the respective at least one diaphragm edge are arranged differently in relation to the total light exit surfaces in the different LED light source module.
    In a variant, it is provided that the LED light source modules are arranged in a horizontal row.
    In this way, the individual segments of the primary optics can be imaged side by side and overlapping to form the desired light distribution in front of the vehicle.
    In addition, it is provided that the focal points of the secondary optics elements of the LED light source modules lie in a common vertical plane, which is spanned by the total light exit surfaces of the primary optics of the LED light source modules, as well as in a common horizontal plane.
    Finally, it is envisaged that, with respect to the respective total light exit surface of the primary optics, the focal points of the secondary optics of the individual LED light source modules will be laterally, i. are arranged offset in the horizontal direction to each other.
    Specifically, it is provided that the foci of the secondary optical elements lie in a lateral edge region of the total light exit surface of the respectively associated primary optics, wherein in a first outer LED light source module, the focal point is closest to the edge of the total light exit surface, and with progression in the direction of the second outer LED light source module the focal point moves away from the edge.
    The foci thus move away from the one edge, but only to the extent that they are still in the "edge area". remain. That the two outer foci are approximately in the range of the width of a segment, i. the width of the light exit surface of a primary optic element apart.
    Advantageously, it is also provided that in the vehicle-internal LED light source module, the focal point comes closest to the edge of the total light exit surface of the primary optics, and in the vehicle outer LED light source module, the focal point furthest from the edge of the total light exit surface of the associated primary optics is removed.
    In terms of a simple low-cost construction of the headlamp, it is when the individual LED light source modules have identical Sekundäroptikelemente.
    Preferably, all distances between light exit surfaces of adjacent LED light sources over the entire headlight are identical, resulting in a simple structure with identical modules, with which a basically homogeneous possible light distribution can be achieved.
    It should be briefly mentioned here that under "homogeneous". It is not understood that across the illuminated area, the light image is the same everywhere bright, but that in the light image, the transitions between areas of different brightness are continuous and no sharp transitions occur. The overall light image should not be "spotty". but have smooth transitions from lighter to darker areas.
    By the present invention, the photograph can be further improved significantly. P12038 * * * * »# #« «« «« »» · · * * ι »» · · * * * * * * I # * *
    Specifically, it is further provided that the overall arrangement of the light exit surfaces of an LED light source module with respect to the optical axis of Sekundäroptikelementes occupies a defined position in the horizontal direction, and wherein the different overall arrangements of the individual LED light source modules from each other different defined position in have horizontal direction with respect to the optical axis of their respective associated Sekundäroptikelementes.
    It can be provided that the light exit surfaces of all LED light source modules of the headlamp are each arranged on one side of a vertical plane through the optical axis of their respective associated secondary optics.
    In addition, it can be provided that exactly one light exit surface of all light exit surfaces of a headlight intersects the optical axis of the secondary optics associated therewith.
    In this case, it is provided that an LED light source comprises at least two LEDs arranged horizontally one above the other, which light emitting diodes are independently controllable, and wherein each of the at least two light emitting diodes on the light exit surface of the primary optic as horizontal Lichtsegmentc - within the vertical of the primary opticsememememned light segment - imaged become.
    Preferably, each LED of an LED light source can be controlled separately.
    In a vehicle headlamp system according to the invention with two headlamps as described above, wherein the left-hand headlamp on the roadway generates the left-hand part of the light distribution and the right-hand headlamp the right-hand part of the light distribution in a vehicle-mounted state, it is provided that preferably at least each LED headlamp Light source, preferably each LED of the two headlights can be controlled separately.
    In particular, it is provided that the left and the right headlamps have a mirror-image construction with respect to the arrangement of the focal points of the secondary optics with respect to the associated primary optics and with regard to the course of the diaphragm edges. -18 PI2038 -18 PI2038 • · · · * * * ·· ··· * • * * * * #

    FIG. 1 shows an LED driving light SW1 for generating a dynamic light distribution, in this case a left-hand headlight, with four LED light source modules M1-M4 arranged in a row. Each LED light source module Ml - M4 has a secondary optics Sl, S2, S3, S4, which the light emerging from the total light exit surface GLF primary optics PG - installed in a vehicle state of the headlamp SWI - as a light image in front of the vehicle lying area.
    FIG. 2 shows such a LED light source module M1 (M2, M3, M4), without secondary optics, in a detailed representation. The LED light source module Ml comprises a plurality of LED light sources LEQ, specifically four such LED light sources, which in turn each consist of at least one light-emitting diode. In Figure 2, the individual LEDs are not visible, Figure 10 shows, for example, LED light sources LEQ with exactly two LEDs LED1, LED2.
    Figures 4 and 5 show the LED light source module of Figure 2 still in a view from above and in a perspective view obliquely from behind.
    Each LED light source LEQ couples light into an associated primary optic element PI-P4, which exits via the respective light exit surface LI-L4 of the primary optic element PI-P4. These light exit surface segments LI - L4 are depicted as light segments in the light image, the superposition of the segments of the individual modules Ml - M4 of the (left) headlamp and those of the right headlamp then give the total light distribution.
    The light exit surface LI-L4 form the total light exit surface GLF, wherein in this variant of the invention the primary optic elements PI-P4 are advantageously connected in an upper region to a connecting web VS1 and preferably also in a lower region to such a web VS2. In these webs VS1, VS2 can also light from the LED light sources LEQ enter, which then exits via the light exit surfaces LF1, LF2 of the webs VS1, VS2 again and contributes to the light distribution and homogenized.

    The light exit surfaces LF1, LF2 of the two webs are thus part of the total light exit surface GLF, and the primary optics PI - P4 and the two webs VSL, VS2, which are preferably integrally formed from the same material, form the so-called primary optics.
    Between the (total) Lichtaustrittsflächeo GLF of the primary optics PG and secondary optics according to the invention is a diaphragm assembly BAO, which in the example shown two optically effective diaphragm edge BK1, BK2, which are arranged and / or extend that in an upper and / or lower portion of the light image occurring, unwanted distortions are at least partially hidden in the photograph.
    In the schematic variant according to FIG. 2, the two diaphragm edges BK1, BK2 are designed as edges of two planar shutters BLEI, BLE2.
    The diaphragm edges BK1, BK2 or their projection into a vertical plane has, for example, a curved course. An aperture edge thus consists of a projection in the vertical plane of one or more curved curve sections.
    FIG. 3 schematically shows a vehicle headlamp system comprising a right-hand headlamp SWr, which is shown at the top in FIG. 3, and a left-hand headlamp SW1, which is shown below. In reality, these two headlights are naturally left and right, preferably in the corner regions of the vehicle front of a vehicle angeord-net and not, as dargesteilt, one above the other.
    In the variant shown, the modules Ml - M4 (ΜΓ - M4 ') of a headlamp have almost the same structure, i. E. identical primary optics PG and identical aperture arrangements will be used, i. identical diaphragm edges BK1, BK2 used.
    The difference between the individual modules Ml-M4 (Ml '-M4') consists in the position of the diaphragm edges BK1, BK2 with respect to the light exit surfaces GLF of the primary optics PG, as will be discussed in more detail below.

    The secondary optics are generally identical in principle, but differ within a headlight and between the headlamps by different Designbeschnitt.
    The Gesamtüchtaustrittsfläche GLF of the primary optics PG, formed from the light exit surfaces LI - L4 of the primary optic elements PI - P4 and the light exit surfaces LF1, LF2 of the connecting webs VF1, VF2 has a defined height and width extension, for example in the form of a rectangle on. The total light exit surface GLF is then this rectangle, minus those areas in which there is no light exit surface, ie in particular those areas between the Primäroptikelementcn and laterally next to the two outer primary optic elements.
    If one considers the left-hand headlight SW1 (for the right-hand headlight SWr, these considerations apply analogously), it can be seen that the focal points FS1, FS2, FS3, FS4 (right headlight SWr: FS1 '- FS4') of the secondary endoscope (not shown) in FIG a lateral edge region RB1 of the total light exit surface GLF lie. The edges BK1, BK2 have a course / contour in which the edges BK1, BK2 have a larger normal distance to the focal point FS1, FS2, FS3, FS4 (ie to a horizontal plane EH through the focal point in the focal point) than to the horizontal plane EH through the focal point in a the edge region RB1, in which the focal point FS1, FS2, FS3, FS4 is located, opposite edge region RB2 the Gesamtlkhtaustrittsfläche GLF.
    In the edge region RB2 farther from the focal point, the diaphragm edge thus has a smaller (normal) distance to this horizontal plane than in the region RB1 of the focal point. For different modules M1-M4, the focal point lies, as can be seen in FIG. 3, at different locations, but always in the edge area RB1.
    The focal point of a secondary optic lies in the (vertical) plane of the light exit surfaces of the primary optics, where the optical axis of the secondary optics penetrates the plane "."
    The normal distance of the diaphragm edge BK1, BK2 to the focal point FS1, FS2, FS3, FS4 of the secondary optical element S1-S4 sets the maximum distance of the diaphragm edge BK1, BK2 to PI 2038. + -. * · ·····················································································································································································: of the horizontal plane EH the normal distance to the horizontal plane EH from.
    The measures described above ensure that in the areas from which the distortions originate, light is correspondingly isolated, while light from the areas with little or no distortion in the photograph is little or not shielded.
    As can also be seen, it is advantageous if the normal distance of the diaphragm edges BK1, BK2 to the focal points FS1, FS2, FS3, FS4 represents the greatest distance between the respective diaphragm edge BK1, BK2 to the horizontal plane EH, and that preferably via the Focal point FSl, FS2, FS3, FS4 having edge region RB1 addition to the normal distance to the horizontal plane EH then remains the same.
    The course of the diaphragm edges BX1, BK2 can be "independent" of each other. However, the diaphragm edges of a module can also, as shown in FIG. 3, have a profile mirrored with respect to a horizontal plane of symmetry (which lies below the plane EH). That is, the top edge, mirrored about the plane of symmetry, yields the bottom edge.
    The horizontal plane through the focal point of the secondary optics is in the example shown, in which a high beam and / or partial high beam is generated, above this horizontal plane of symmetry through the total light exit surface (see above).
    In the case of a headlamp a little for low beam, the plane EH lies in the symmetry plane of the primary optics.
    Thus, in the example shown, the upper edge BK1 has a smaller normal distance, preferably along the entire horizontal extent, to a horizontal plane EH through the focal point FS1, FS2, FS3, FS4 of the secondary optic element S1-S4 than the lower edge BK2 (in each case with respect to FIG a defined point along the horizontal plane).
    To produce a desired light image (high beam, partial high beam), the horizontal plane lies through the focal point of the secondary optics above this plane of symmetry, which is why the different distances of the two diaphragm edges to the horizontal plane result from the focal point of the secondary optics.
    The light image is trimmed correspondingly less in the lower area than in the upper area (the lower area results from projection of the upper area of the light exit area by means of secondary optics and vice versa).
    In principle, the upper and lower edges can have any desired shape, in particular any desired shape, with respect to the specific profile, i. Any symmetries between the upper and lower edge are not absolutely necessary.
    The secondary optics elements of the LED light source modules Ml, M2, M3, M4; Ml /, M2 ', M3', M4 'and the arrangement of the light exit surfaces GLF of the primary optics PG are coordinated such that the light segments from the individual LED light source modules Ml, M2, M3, M4; Ml ', M2', M3 ', M4' are shown offset in the horizontal direction to each other. The individual LED light sources can be controlled separately.
    The LED light source modules Ml - M4; Ml - M4 'of a headlamp are each arranged in a horizontal row, so that the individual segments of the primary optics lie next to one another and are overlapped to form the desired light distribution in front of the vehicle.
    The focal points FS1-FS4, FS1-FS4 'of the secondary optical elements of the LED light source modules lie in a common vertical plane, which is spanned by the total light exit surfaces GLF of the primary optics PG of the LED light source modules, and in a common horizontal plane EH.
    With respect to the respective total light exit surface GLF of the primary optics PG, the foci FSl-FS4, FSl'-FS4 'of the secondary optics of the individual LED light source modules are laterally, i. arranged offset in the horizontal direction to each other.
    In this way, an optimal overlap of the individual segments of the individual primary optic elements is achieved.
    Specifically, it is provided that the foci FS1 - FS4, FSI '- FS4' of the secondary optics each lie in a lateral edge region RB1 of the total light exit surface GLF of the respectively associated primary optics PG, wherein in a first outer LED light source module Ml, Ml '( the vehicle-inner module), the focus FSl, FSl 'is closest to the edge of the total light exit surface GLF, and with advancement toward the opposite outer LED light source module M4, M4' (vehicle exterior) of the headlamp, the focus FS2-FS4 'FS2' - FS4 'moves away from the edge.
    The foci therefore move away from the one edge, but only to the extent that they remain in the "edge region". RB1 remain. That the two outer foci (FIG. 3: FS1, FS4 and FS1 ', FS4') are approximately in the region of the width of a segment, ie. the width of the light exit surface of a primary optic element apart.
    The displacement of the individual focal points with respect to the edge depends on the width of the segments (width of the light exit surfaces of the primary optics elements) and is selected such that a desired flomogeneity and resolution of the light distribution results. For example, in the variant shown, it is provided that the distance from the focal point FS1 to FS3 (if the four modules were superimposed on one another) is the same as the width of the light exit surface of the attachment optics. Thus, it is ensured that module M1 and module M3 provide full light distribution (i.e., module M3 illuminates into the gaps of module M1). The foci of FS2 and FS4 also have the same distance to each other and also give a full light distribution. However, the distance between FSl and FS2 or FS3 and FS4 is not a whole, but only half a segment width. These overlays give a better resolution and the homogeneity of the (far) light also gets better.
    It is thus provided that in the vehicle-internal LED light source module Ml Ml 'the focal point FSl, FSl' comes closest to the edge of the total light exit surface GLF of the primary optics PG, and in the vehicle outer LED light source module M4, M4 'the focal point FS4, FS4' farthest from the edge of the total light exit surface GLF of the associated primary optics PG is removed.
    As can be seen, if the diaphragm or the diaphragm edges are fixed relative to the focal point of the secondary optics, i. in a specific embodiment, the aperture can be fixed to the projection lens (secondary optics).
    The primary optics are thus displaced horizontally laterally relative to the projection lenses and diaphragms. The projection lens can thus preferably form a structural unit with the diaphragm, for example the diaphragm can be fastened on the lens holder.
    FIG. 6 shows an exemplary, schematic light distribution generated with a single LED light source module without a diaphragm arrangement according to the invention. As you can see, the light image is increasingly distorted with increasing distance from the vertical 0 ° line.
    FIG. 7 shows an exemplary, schematic light distribution of a module as used in FIG. 6, but now with the interposition of an aperture arrangement according to the invention. As can be clearly seen in the figure, here the light image no longer has any appreciable distortions.
    Figure 8 shows again - analogous to Figure 1 - a vehicle headlight with four LED light source modules Ml - M4 in a row. The diaphragm arrangement BAO here includes - see also in detail also FIG. 9 - two optically effective diaphragm edges BK1, BK2, which are formed in a single diaphragm BLE.
    As can be clearly seen in FIG. 10, the diaphragm edges BK1, BK2 or the projections of the two diaphragm edges BK1, BK2 consist of a vertical plane comprising a plurality of straight-line sections All, A1, A13, A14, A15, A16, A21, A22, A23, A24, A25, A26. For example, the transition between two rectilinear sections is discontinuous, e.g. as shown in the form of an edge.
    Figures 11 and 12 show the module of Figure 8 further still in a view from the side or obliquely from behind.
    FIGS. 13 and 14 also show an LED light source module with a diaphragm arrangement BAO as in FIG. 8, with the difference that the diaphragm arrangement BAO is formed integrally with P12U38. * at * · * «· · · · * * * ♦
    a holder HAL is designed for the primary optics PG. In other words, the diaphragm edges BK1, BK2 are formed in the holder HAL for the primary optics PG. The holder HAL basically consists - not only if the panel edges are formed on it - of a non-translucent material, otherwise light could also propagate in the holder, whereby the optical function would be impaired - even to non-functioning. The holder attaches the primary optics PG to the LED-Print PRI.
    In the embodiments described above, which require little space and provide visually very good results, it is provided in each case that the diaphragm is planar or that the diaphragm edges BK1, BK2 in a vertical plane, which is parallel to the total light exit surface PG of the primary optic element , lie. The aperture is flat and is normal to the light exit direction in the beam path.
    FIG. 15 shows a further variant in a view from above, in which the diaphragm BLE (and thus the one or both diaphragm edges) is curved in the horizontal direction, the curvature preferably corresponding substantially to the field curvature of the secondary optical element or following this field curvature , The diaphragm BLE is curved away from the light exit surface of the primary optic element.
    The curvature of the at least one diaphragm edge (in a horizontal plane) follows the field curvature of secondary optics, or
