Definitions
- the invention relates to an LED light source module for an LED motor vehicle headlight, in particular for an LED motor vehicle headlight for generating a dynamic light distribution, wherein the LED light source module comprises two or more LED light sources, wherein an LED light source respectively from at least one light emitting diode, and wherein the light-emitting diodes of each LED light source couple light into an associated primary optic element, wherein the coupled-in light exits at least partially from a light exit surface of the primary optic element.
- the invention further relates to a headlamp with such an LED light source module and a corresponding headlamp system.
- 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.
- 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.
- object lighting for example, objects on the roadside, such as pedestrians, but also traffic signs, with light, e.g. with infrared light, illuminated, and these objects can then be captured with an infrared camera.
- visible light such as traffic sign lighting can be used.
- the above tasks can be realized by selective activation or in the latter case by selectively deactivating certain LED light sources.
- certain LED light sources there are currently electronic solutions in which only certain LED light sources are activated or deactivated, so that only the desired LED light sources emit light on the street. This solution offers a high degree of flexibility, as basically any LED light sources are activated.
- such a headlamp can be realized with conventionally available LED light sources.
- individual light functions such as low beam, high beam, cornering light, etc.
- the luminous area is divided into segments which can be switched separately.
- the light originating from the LEDs is projected onto the roadway as a segmented light distribution via the individual primary optics, which form the individual segments of the light exit surfaces, and the associated secondary optics.
- 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 Lichtaustrittsflä- 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.
- a 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.
- 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.
- the light exit surfaces of the primary optic elements are connected to one another in an upper and / or lower region.
- the primary optic elements are in any case connected to one another in the upper region.
- the terms “top” and “bottom” refer to the state of the module / headlamp installed in the vehicle. This upper area is displayed 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.
- At least one substantially horizontally extending connecting web which is formed from the translucent material, is provided, which connects the primary optics elements in the upper and / or lower region of their light exit surfaces.
- the at least one connecting web is formed integrally 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.
- 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.
- 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.
- 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.
- the design of the one or more connecting webs in particular the extension of the / the connecting web (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, ie, the more homogeneous the light image is selected more strongly the maximum is reduced.
- 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 chosen such that the desired degree with respect to the homogeneity of the photograph and the desired degree of reduction of the maximum in the light distribution result.
- the at least one, in particular the upper, connecting web in the direction of the light coupling points of the primary optic elements is designed to be, for example, wedge-shaped, tapered.
- the wedge shape can save material, which leads to a cost reduction. This applies in particular, the farther the connecting bridge extends to the rear.
- a cuboid, that is, not tapered configuration of the connecting web brings in optical terms no advantages over the tapered shape, so that the latter is chosen with advantage.
- the primary optic elements expand 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.
- 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.
- light exit surfaces of different shape for example, with different widths (horizontal extent) are used. For example, certain areas of the light distribution can be generated with narrower light exit surfaces, resulting in a finer segmentation of the light image there and smaller or narrower areas can be hidden.

- the light exit surfaces of the primary optic elements of an LED light source module are arranged at a horizontal distance next to each other.
- 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.
- a homogeneous light distribution such as a high beam distribution can 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 very specific areas of light distribution "hidden", ie can not be illuminated, for example, to avoid dazzling oncoming traffic.
- the individual light segments can be arranged directly adjacent to one another in the horizontal direction.
- 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 in detail later, by hiding, for example, two light segments, areas from the light distribution can be "hidden" or not illuminated, which are narrower than a light segment.
- the light exit surfaces are vertically standing, of greater height than width, e.g. in the form of rectangles or ellipses etc.
- adjacent light exit surfaces of the primary optics elements of an LED light source module have a normal distance from each other, which corresponds to the width of a light exit surface, and 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 its secondary optics by half / single / double / quadruple / ((n-1) / 2) compared to the first overall arrangement f a normal distance between two adjacent light exit surfaces of an LED light source module is shifted.
- the distances between light exit surfaces of adjacent primary artefacts elements and the same are preferably all distances between the light exit surfaces of adjacent LED light sources over the entire headlight identical.

- the secondary optics elements of the LED light source modules and the arrangement of the light exit surfaces of the primary optics elements are matched to one another in such a way that the light segments from the individual LED light source modules are offset from one another in the horizontal direction, and the individual LED - Light sources are controlled separately.
- 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.
- the term “homogeneous” does not mean that the light image is the same everywhere over the illuminated area, but that the transitions between areas of different brightness are continuous in the light image and no sharp transitions occur not be “spotty” but have smooth transitions from lighter to darker areas.
- the photograph can be further improved significantly.
- the overall arrangement of the light exit surfaces of an LED light source module with respect to the optical axis of Sekundäroptikiatas 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 Sekundäroptikimplantations.

- 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.
- the primary optic elements are preferably connected to one another in the upper region.
- the terms “top” and “bottom” refer to the state of the module / headlamp installed in the vehicle.
- This upper area is displayed via the secondary optics in the photograph below the cut-off line, where the unwanted inhomogeneities are most disturbing.

- FIG. 8 shows a variant in which the web VS1 extends backward over an even larger area ES, and the upper connecting web VSl is also designed to taper in the direction of the light coupling points of the primary optics elements.
- the connecting web or its extent ES backwards reduces the maximum of the illuminance. Therefore, the extent of extension ES backwards represents a compromise between maximum and homogeneity. The more homogeneous the light distribution should be, the greater are the losses at the maximum (Hmax) of the light distribution.
- the homogenization effects achieved by the connecting web thus depend on the extent of the extent ES to the rear.
- the tapered shape has no visual impact, but saves material. From a purely optical point of view but would also be a cuboid shape of the connecting web possible.

- FIG. 11 shows the light exit surface of a primary optic element PG according to FIGS. 4-7, and
- FIG. 12 shows a primary optic PG according to FIGS. 8 and 9.
- the light emerging from these light exit surfaces is projected onto the carriageway via the secondary optics elements.
- asymmetrical feeding means that the light is coupled in at the top and not exactly in the geometric center of the light coupling point of the primary optics elements.
- the Hmax region is located on the decoupling surface in the upper region and not in the center.
- the secondary optics projection lens
- the occurring light distribution at the decoupling surface of the primary optics is reproduced exactly.
- the illustrated primary optics so exactly 4 light fingers (4 segments) are generated and filled the spaces with the light fingers of another module. At the edges below (and also above) there are strong inhomogeneities in the overlay, which leads to fraying of the light image.
- the upper / lower region between primary optic elements PI-P4 is illuminated even more strongly than in the variant in FIG. 11.
- the HI areas almost touch each other.
- the overlapping of the gaps with the light fingers of another module results in a homogeneous light distribution.
- HI areas of adjacent light modules overlap almost completely.
