Description

The invention relates to a lighting device for a motor vehicle headlamp, which comprises a lighting unit with at least one light source and at least one attachment optics, wherein the at least one attachment optics has a plurality of light guide elements and a light exit surface, wherein each light guide element has a light input surface for feeding light at least one light source , and wherein light outcoupling surfaces of the light guide elements open in the common light exit surface of the attachment optics.

A lighting device of this kind is for example from the document WO 2013/166535 A2 known. Essential for a practicable light image is in such a lighting device for a motor vehicle headlight, the formation of the optical attachment with appropriate light-guiding elements, in which the light is guided by total reflection at the boundary walls.

A disadvantage of such known from the prior art lighting devices is usually that forms undesirable scattered light around the individual matrix segments in particular in versions of the primary optics as a matrix system. This scattered light formation adversely reduces the imaging quality of the individual matrix segments. In addition, due to the scattered light - depending on the respective legal regulation - problems in the homologation of motor vehicle headlights due to the norms and limits to be observed come.

One of the objects of the invention is to optimize the shape of the attachment optics, in particular with regard to an even better homogeneity and maximum brightness of the generated photo, in a lighting device of the subject type. Moreover, a generic lighting device is to be specified, which overcomes the disadvantages known from the prior art.

These objects are achieved with a lighting device of the type mentioned, in which the light exit surface of the optical attachment at least partially has a Lichtauskoppeloptik with convex curvature and Auskoppelrillen at the edges of the Lichtauskoppeloptik, each having a plurality Lichtleitelemente associated with their Lichtauskoppelflächen a Lichtauskoppeloptik.

Thanks to the invention results for each inventively designed lighting device, a light distribution with less disturbing areas, less scattered light component, and a higher maximum light intensity at the light exit surface of the attachment optics or in the generated photograph. Through the use of one or more light extraction optics, which are arranged in the light exit direction on the light exit surface of the optical attachment, the light image generated by the light guide elements can be improved, the imaging quality of individual light sources or individual light guide can be increased and the formation of unwanted scattered light can be reduced. The light exit surface has for this at least in sections or over its entire surface distributed on one or more Lichtauskoppeloptiken, each Lichtauskoppeloptik having a convex curvature and has Auskoppelrillen at their edges. In each case a plurality of light-guiding elements are associated with their light outcoupling surfaces of a light extraction optics. With this embodiment of a lighting device according to the invention, moreover, further advantages can be achieved: For example, the homologation of newly developed motor vehicle headlights can be made simpler, since the person skilled in the art has at his disposal a suitable means to reduce or avoid unwanted stray light formation. In addition, advantageous lighting effects can be achieved with a lighting device according to the invention. For example, by using suitable light extraction optics, a cornering light can be drawn further outwards.

Advantageously, a plurality of light-guiding elements may be integrally connected to one another in their front region, that is to say that region which comprises the light outcoupling surfaces of the light-guiding elements in the light exit direction, since this facilitates the manufacture and leads to a compact and stable optical attachment. It may be useful if the light outcoupling surfaces of the light guide coincide with the light exit surface of the attachment optics.

In a lighting device according to the invention, a plurality of light-guiding elements may expediently be arranged in a matrix arrangement in at least one matrix row and in a plurality of matrix columns. For example, the light-guiding elements can be arranged in a matrix arrangement in two or three lines and in numerous matrix columns next to one another. In the following, the matrix arrangement will also be described on the basis of directional information for easier representation. Accordingly, matrix lines are arranged essentially in the horizontal direction, while matrix columns run essentially in the vertical direction. This association of the terms with respect to a location or orientation, such as "horizontal", "vertical", "horizontal direction", "vertical direction", "top", "bottom", "front", "below", "above" etc. are chosen in the description for convenience only and may refer to the illustration in the drawings, but not necessarily to a use or mounting position of the lighting device or the motor vehicle headlight.

The term matrix arrangement should also apply in the context of the subject application in the extreme case in which the matrix is a single line, thus only a number of light-guiding elements is present, which makes sense in the automotive lighting technology.

Experience has shown that the construction of a lighting device for a motor vehicle headlight or a light module with a matrix-like arrangement is particularly efficient when the light guide elements are arranged in exactly three superimposed matrix rows or rows, which together form a high beam distribution. In such an arrangement, the upper matrix row may be formed as a front row row, the middle matrix row as an asymmetry row, and the lower matrix row as a high beam row, wherein the high beam row may be configured with high-beam light-guiding elements with corresponding constrictions.

Each light-guiding element is preferably assigned a light source, in particular an LED or a plurality of LEDs. In the context of the invention, however, a plurality of light sources can also be assigned to a light-guiding element or vice versa, depending on the design, a single light source can also be assigned to a plurality of light-guiding elements. Likewise, other light sources can be used as LEDs. The light-guiding elements can be produced, for example, from highly transparent, photoconductive and moldable plastics which are well suited for the production of complex geometries. Silicone materials are particularly preferred. However, it is also the use of glasses possible. In the case of integrally interconnected light-guiding elements or a one-piece lighting unit, the use of plastics for producing the lighting unit and / or the light-guiding elements is preferred.

It can be particularly advantageous if, in the case of a lighting device according to the invention, a plurality of light-conducting elements which are arranged next to one another line-by-line in a matrix line are assigned to a light-extraction optical system. Suitably, in this embodiment, a plurality of light-guiding elements are assigned line by line to a common light-extraction optical system. Thus, the image quality of several light-guiding elements can be improved line by line very efficiently. Optionally, all light guide elements, the are arranged side by side in a matrix row, be associated with a single light extraction optics.

In other cases, it may be advisable if, in the case of a lighting device according to the invention, the light-guiding elements arranged in at least two spaced-apart matrix lines are assigned line by line to different lines of light-extraction optics which are also spaced apart from one another. Thus, the imaging quality of the matrix-like arranged light guide elements can be improved line by line by the use of line-wise associated Lichtauskoppeloptiken.

Particularly advantageously, in a lighting device according to the invention, light-guiding elements arranged line by line in two directly adjoining matrix lines can be assigned light extraction optics line by line, directly adjacent lines of the light extraction optics having an intermediate coupling-out groove. The one or more Auskoppelrillen may extend on the light exit surface of the attachment optics in the longitudinal direction or in the row direction of the light extraction optics along a plurality of light guide elements. Likewise, one or more Auskoppelrillen may extend in the longitudinal direction or in the row direction along the entire length of the light exit surface.

In a further preferred embodiment of the invention, one line of the light extraction optics can be assigned to each matrix row of light-guiding elements in a lighting device.

According to a further preferred embodiment of the invention, in an illumination device, a contour shape of the convex curvature of a light extraction optical system can be selected from a group comprising: circular segment, ellipse segment, freeform curve segment. Advantageously, differently contoured light extraction optics can be used in this embodiment. For example, it is possible to use a lighting device in which a three-row matrix arrangement of light-guiding elements with an optical attachment, which is equipped with differently shaped light-extraction optics line by line on the light exit surface, is improved in its light image. By way of example, the first of three matrix rows of light-guiding elements can be assigned a first light-extraction optical system which has a convex curvature with the contour of a circle segment with a radius of 10 mm. By way of example, the middle of three matrix rows of light-guiding elements can be assigned a second light-extraction optical system which has a convex curvature with the contour of a circle segment with a radius of 5 mm. For example, the lower of be associated with three matrix lines of light guide a third light extraction optics, which has a convex curvature with the contour of a free-form surface.

Likewise, the light exit surface of the attachment optics can be structured in such a way that a planar section or a planar line of the light exit surface is provided adjacent to a section or a line of a light extraction optical system with a contoured convex curvature. Such planar sections of the light exit surface can also be provided between two attachment optics.

In a further development of the invention, the contour shape of the curvature of a plurality of lines of the light extraction optics can each be designed the same in a lighting device. In this expedient embodiment, which can be produced cost-effectively, the light exit surface of the attachment optics is coated with lines of light extraction optics of equal contour. Expediently, in a preferred variant, the same number of lines are provided on light extraction optics as matrix lines on light-guiding elements.

In an alternative development of the invention, in the case of an illumination device, the contour shapes of the curvature of at least two lines of the light extraction optics may be different. In this embodiment, the imaging quality of individual light sources or individual light-guiding elements can be increased in a particularly flexible manner.

In a lighting device, each row of the light extraction optics can particularly advantageously have a constant width and a uniform contour shape of the curvature in the row direction. In this embodiment, the Lichtauskoppeloptiken line by line or in the row direction are respectively homogeneous, which is advantageous for cost-effective production.

In an alternative embodiment of the invention, at least one row of the light extraction optics in the row direction may have different widths and / or different heights and / or different contour shapes of the curvature at least in sections in the case of a lighting device. In this embodiment, individual or even a plurality of light extraction optics in the longitudinal direction or in the row direction along the length of the light exit surface of the optical attachment sections may have different dimensions. For example, it may be expedient if a row-wise arranged light extraction optics in their middle section a greater width and / or a greater height and a convex curvature with a larger Radius of curvature - and thus a greater material height - than at their lateral edge portions in each case to the narrow sides of the attachment optics.

In a further preferred embodiment of the invention, in the case of an illumination device, at least one light extraction optical system can have a surface section with microstructures of a roughened surface. Such microstructures in the area of the light extraction optics can for example offer the advantage that a particularly homogeneous light image is generated by the illumination device. By way of example, such microstructures may be embodied as scar-like roughness on the surface of the light-extraction optical system, the characteristic lengths of which may have an order of magnitude of, for example, 5 μm (micrometers). Advantageously, this graining can be applied at least in sections to the light extraction optics associated with the front row row.

It may be advantageous if, in the case of an illumination device, the light exit surface of the attachment optics is a surface bent kink-free in the longitudinal direction or in the row direction, preferably a Petzval surface bent without kinking. The light exit surface thus advantageously has no creasing edges in the direction of the matrix columns, that is to say substantially in the vertical direction, in particular in the case of a matrix arrangement of the light guide elements. Thus, the light extraction optics in the row direction and in the longitudinal direction no disturbing kinks or interruptions. The Lichtauskoppeloptiken be limited only by the Auskoppelrillen, which run in the direction of the matrix lines, ie in a substantially horizontal direction.
The common light exit surface is typically a curved surface, which usually follows the Petzval surface of the imaging optics, for example an imaging lens. For certain applications, however, deliberate deviations in the curvature can also be used in order to use aberrations for light homogenization in the edge region.

In the context of the invention, a light module can also be specified with at least one illumination device according to the invention. If the term "headlight" is used in connection with the invention, then this term should also include individual light modules or projection modules, which may also be included in combination in a higher-level headlight.

In the context of the invention, however, it is also possible to use a vehicle headlight with at least one illumination device and / or with at least one light module with at least one illumination device according to the invention. For example such a vehicle headlamp may further comprise a projection optics disposed downstream of the light unit in the light exit direction.

Fig. 2 shows a lighting unit 2 with an optical attachment 4 obliquely seen from the rear in the direction of light coupling surfaces 61 of the light guide 6. Each light coupling surface 61 of the light-guiding elements 6 here is assigned an LED as the light source 3. The light-guiding elements 6 open with their light outcoupling surfaces 62 in each case in the common light exit surface 5 of the attachment optics 4. The light-guiding elements 6 are arranged in matrix arrangement 7 here in three matrix rows 71 and in a multiplicity of matrix columns 72. The matrix lines 71 are according to Fig. 2 oriented substantially in the horizontal direction, while the matrix columns 72 are aligned substantially in the vertical direction.

Fig. 3 shows a first embodiment of a front optical system 4 according to the invention seen from the side. Here, too, the light-guiding elements 6 in matrix arrangement 7 are arranged here in three matrix rows 71. As can be seen here in the side view, the optical attachment 4 is without curvature in the longitudinal direction and thus flat. At the light exit surface 5 of the optical attachment 4 three Lichtauskoppeloptiken 50 are arranged here line by line, each matrix line 71 is assigned to light-guiding elements 6 of a Lichtauskoppeloptik 50.

The lower line 51 of the light extraction optical system 50 here has, for example, a convex curvature 56 with a contour shape 57 of the curvature, which corresponds to a circular segment. The middle row 51 of the light extraction optical system 50 here has, for example, a convex curvature 56 'with a contour shape 58 of the curvature that corresponds to an ellipse segment equivalent.

According to this embodiment, it can be seen that light extraction optics 50, which have a uniform height 54 in the longitudinal direction 52 or line direction of the light extraction optics 50, are arranged on the light exit surface of the optical attachment 4.

Fig. 5 shows the in Fig. 4 shown second embodiment of a front lens 4 according to the invention seen in an isometric view obliquely from the front. The lower line 51 of the light extraction optical system 50 here has, for example, a convex curvature 56 with a contour shape 57 of the curvature, which corresponds to a circular segment. The middle row 51 of the light extraction optics 50 here has, for example, a convex curvature 56 'with a contour shape 58 of the curvature, which corresponds to an elliptical segment. The upper line 51 of the light extraction optical system 50 here has, for example, a convex curvature 56 "with a curvature contour shape 59, which is formed as a free-form curve segment.From the individual lines 51 of the light extraction optics 50, outcoupling grooves 55 for delimiting the light extraction optics 50 are provided at their edges In the longitudinal direction 52 or in the row direction of the light extraction optics 50, these each have constant widths 53 and constant heights 54. The convex curvatures 56, 56 ', 56 "or the respective contour shapes 57, 58, 59 of the light extraction optics 50 are therefore in the longitudinal direction 52 and in the row direction in each case uniformly designed.

Fig. 6 shows a third embodiment of a front lens 4 according to the invention seen from above. The attachment optics 4 is designed here as a kink-free curved Petzval surface 41. In contrast to the execution according to Fig. 4 is at the in Fig. 6 shown embodiment, that at the light exit surface 5 of the optical attachment 4, a Lichtauskoppeloptik 50 is arranged, which in the longitudinal direction 52 and line direction of the light extraction optics 50 different heights 54, 54 'have. Here, the upper Lichtauskoppeloptik 50 approximately in the middle of its longitudinal direction 52 has a height 54 ', which is greater than the material thickness with a height 54 at the two lateral edge portions of the upper Lichtauskoppeloptik 50th

Fig. 7 shows the in Fig. 6 illustrated third embodiment of a front lens 4 according to the invention seen in an isometric view obliquely from the front. The lower line 51 of the light extraction optical system 50 here has, for example, a convex curvature 56 with a contour shape 57 of the curvature, which corresponds to a circular segment. The middle row 51 of the light extraction optics 50 here has, for example, a convex curvature 56 'with a contour shape 58 of the curvature, which corresponds to an elliptical segment. The upper line 51 of the light extraction optical system 50 here has, for example, a convex curvature 56 "with a curvature contour shape 59, which is formed as a free-form curve segment. Between the individual lines 51 of the light extraction optics 50, outcoupling grooves 50 for delimiting the light extraction optics 50 are again arranged at their edges The lower two light extraction optics 50 each have constant widths 53 and constant heights 54 in the longitudinal direction 52 or in the row direction of the light extraction optics 50. The upper light extraction optics 50, which by way of example has an outline shape 59 of the curvature, which is designed as a freeform curve segment 5 has different widths 53, 53 'and different heights 54, 54' in the longitudinal direction 52 or in the row direction of the light extraction optical system 50. Here, the upper light extraction optical unit 50 has a width 53 'approximately midway in its longitudinal direction 52 which is smaller than its width 53 ever The upper light extraction optics 50 are further equipped with a roughened surface 9 having microstructures 90 with characteristic lengths on the order of about 5 μm (microns) here.

The following explanation of the comparison of FIGS. 8 to 11 makes the advantages of the invention even clearer.

Fig. 8 shows, for example, a light distribution of a single light-guiding element of a lighting unit, which is formed according to the invention with a light extraction optics on the light exit surface of the optical attachment, with drawn lines of the same intensity.

Fig. 9 shows a diagram of the course of the light intensity Iv along the plotted center line z of Fig. 8 , where the left side of the diagram is the lower part of the diagram Fig. 8 equivalent.

Fig. 10 corresponds to the representation of the Fig. 8 However, here was measured a light guide of a light unit according to the prior art, which has a planar light exit surface of the optical attachment without a light extraction optics. It can be seen undesirable stray light regions on both sides of the desired light image, which are less pronounced in the light guide according to the invention, as opposed to the Fig. 8 shows. In addition, a less steeply sloping intensity curve in the lower and in the upper region of the light intensity profile in comparison to a light guide with coupling optics according to the invention can be seen, which is represented by the vertically spaced further lines of the same light intensity.

In Fig. 11 , which in itself the diagram of the Fig. 9 corresponds, but was determined for a light guide according to the prior art without a light extraction optics at the light exit surface of the optical attachment, it can be seen that the light intensity curve Iv has a lower maximum light intensity, than that of a light guide according to the invention, as the comparison with the opposite Fig. 9 shows. Also, the disadvantageously less steep drop in the left and right of the light intensity profile can be seen.

With a motor vehicle headlight of the type shown, for example, a dipped beam or a high beam can be generated, for example, the left headlight and the right headlights are each designed as inventive headlights, with which each of the left and right part of the light distribution of a correspondingly equipped motor vehicle are generated. On the other hand, or alternatively, the left and right headlamps of a motor vehicle equipped with headlamps according to the invention can also each produce identical photographs, which overlap in advance on the road.
