Description

The present invention relates to a projection light module for a motor vehicle headlight according to the preamble of claim 1.

Such a light module is known per se and has a light source, a light of the light source to an intermediate light distribution bundling primary optics, a the intermediate light distribution with a diaphragm edge delimiting mirror aperture, a limited light distribution in a front projection of the light module projecting projection lens and a light source with the primary optics, the mirror aperture and the projection lens retaining first holding structure. The first support structure has a lens carrier having a light source side end and a projection lens side end. The projection lens side end has a lens mount , which is adapted to receive the projection lens and hold by positive engagement and / or traction.

Numerous types of projection light modules for motor vehicle headlights are known from the prior art. Classic poly-ellipsoidal headlamp modules (PES modules), whose name is derived from the shape of the reflectors used as primary optics, usually have reflectors with internal light source as well as lying in the light flux of the light source and lens elements. Also known are modules with semiconductor light sources, in particular with light-emitting diodes or laser diodes, which are attached in thermal contact with a heat sink at this. At this usually massive heat sink and the aperture and lenses are attached.

The projection lenses of known light modules are mounted in lens carriers by springs, retaining rings, clamps, welding, overmolding and so on. If the known light modules have heat sinks and a lens carrier, this does not contribute to the cooling.

For almost all light modules, a mechanical color fringe adjustment is required. The undesired color fringe produced by a projection light module results from the different refractive power of the projection lens for different wavelengths. Whereas the light beams of different wavelengths / colors refracted at different parts of the projection lens overlap in the bright area of the light distribution to white light, a fringing color appears at the light-dark boundary of the light distribution produced by the mirror aperture. With what intensity such a fringe of color appears ultimately depends on Bauteilmaßtoleranzen and mounting tolerances, which affect the distance of the diaphragm edge of the projection lens and the aperture-side cutting width of the projection lens. Under the intersection is the distance from the outer surface apex of the projection lens to the object surface to understand. In the object surface, the diaphragm edge is preferably arranged.

With the mechanical color fringe adjustment, the distance in the light module assembly is adjusted so that the color fringe minimizes, i. appears with the least possible intensity. Without such a color fringe adjustment, the color of the light, depending on the size of the tolerances, would constantly fluctuate at the roadside cut-off, which is annoying.

From the above-mentioned prior art, the present invention differs by the characterizing features of claim 1. The invention is characterized in that the lens carrier is divided into a first component and a second component, wherein a separating surface lying between the two components Lens receptacle intersects that the mirror aperture between the first component and the second component is clamped, wherein the position of the mirror aperture relative to the two components of the lens carrier is defined by interlocking positive locking elements, and that the mirror aperture in the direction of the projection lens facing spacers, which touch the projection lens.

Characterized in that the lens carrier in a parting surface in a first component and a second component divided, which dividing surface intersects the lens mount, the assembly of the projection light module is first simplified. The projection lens can be easily inserted into the lens receptacle of the one component, the holder being completed by adding the second component. Flanging or otherwise reshaping an edge of a lens mount that reduces the diameter of an undivided lens mount after insertion of the projection lens, which is required in undivided lens shots to hold the projection lens used, can be dispensed with.

The fact that the position of the mirror aperture is fixed relative to the two components of the lens carrier by interlocking positive locking elements, results in a very simple installation of the mirror aperture in conjunction with a very high accuracy of the position of the diaphragm edge with respect to the lens carrier. The clamping attachment also contributes in conjunction with the positive positional fixation to a very low installation costs. The fact that the mirror aperture has spacers pointing in the direction of the projection lens, which contacts the projection lens, results in a very high degree of accuracy in determining the distance between the diaphragm edge and the light entry surface of the projection lens in conjunction with a very low installation effort.

As a result, the intensity with which a fringe appears will be dominated by device manufacturing tolerances. The mounting tolerances can be neglected on the other hand. A Farbsaumeinstellung is then unnecessary if the remaining inaccuracy of said distance is not greater +/- 0.2 mm, which is achievable with a common manufacturing accuracy of the parts.

The omission of Farbsaumeinstellung possible without loss of quality in the low beam reduces the manufacturing cost and production costs, which is an essential development goal. Low cost also contributes to lens attachment without additional parts for standard lens edge geometries. In addition, the invention allows a waiver or at least a use of smaller heat sink than in the prior art. Overall, there is a simplified production in conjunction with lower tolerances and a reduction of space, weight and cost. The object of the invention can therefore be seen in the specification of a projection light module, which has these advantages and in particular is very inexpensive to produce with acceptable lighting properties.

A preferred embodiment is characterized in that the separating surface intersects the light source side end and the projection lens side end of the lens carrier.

It is also preferred that the separating surface extends where the projection lens has its largest diameter and extends in such a way that the projection of the separating surface onto the main plane of the projection lens is a straight line.

In one embodiment, the mirror cover has local matting. In a further refinement, the mirror aperture is arranged horizontally so that its diaphragm edge is imaged by the projection lens as a cut-off line of a dimming beam distribution that complies with the regulations.

Further, it is preferred that the spacers be so long as to contact the projection lens with a slight bias.

It is understood that the features mentioned above and those yet to be explained can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention.

In this case, the same reference numerals designate the same or at least functionally comparable elements in different figures.

In detail, the shows FIG. 1 an embodiment of a projection light module 10 according to the invention for a motor vehicle headlight with a light source 12, a primary optics 14 and a projection lens 16. In addition, the projection light module 10 has a mirror aperture 18, which can be seen even more clearly in other figures. The projection light module 10 has a first holding structure 17, which holds the light source 12, the primary optics 14, the mirror aperture 18 and the projection lens 16.

FIG. 2 shows the projection light module 10 from the FIG. 1 in an exploded view. The first holding structure 17, which holds the light source, the primary optics, the mirror aperture 18 and the projection lens 16, has in particular a lens carrier 20 which has a light source side end 22 and a projection lens side end 24. The projection-lens-side end 24 has a lens mount, which is adapted to receive the projection lens 16 and to hold it by positive engagement and / or frictional connection.

The lens holder has, for example, groove-shaped receptacles 25 which, by their dimensions and arrangement, are set up to embrace projections 27 which project in a coronary manner out of an edge of the projection lens 16.

In another embodiment, the projection lens has recesses at its edge, which are set up by their dimensions and arrangement directed outward projecting projections to fit the edge of the lens holder and the interior of the projection lens.

Between its two ends 22 and 24, the lens carrier 20 is divided into a first component 26 and a second component 28. The division runs in such a way that a separating surface lying between its two constituents 24 and 26 intersects the light source-side end 22 and the projection-lens-side end 24. The separation surface preferably extends through the projection-lens-side end 24, where the projection lens 16 has its largest diameter, and the separation surface extends beyond that in such a way that its projection onto the main plane of the projection lens 16 is a straight line. It is essential that the separating surface cuts the lens holder so that the projection lens 16 can be received in the split lens holder without plastic deformation of the components of the lens carrier 20. The separation surface must therefore intersect the projection lens-side end 24 with the lens holder. However, it is not absolutely necessary that the separating surface also intersects the light source-side end 22 of the lens carrier 20. The separating surface may also have one or more angles, run in several planes and / or have one or more steps as further form-fitting elements.

The FIG. 3 shows an embodiment of the first component 26 of the lens carrier 20 as a half-shell. The separation surface is in the illustrated case a flat separation surface. The half-shell has in its parting surface a first flange 26.1 and a second flange 26.2. Each flange has n = 2 form-locking elements, which are realized in the example shown as bores 30. The number n of form-fitting elements can also be larger be as two. The bores 30 are each located in the vicinity of opposite flange ends of a flange, so that their distance from each other along an imaginary connecting line of the bores 30 is greater than their lying in an extension of the connecting line distance from the nearest flange end of the flange. Between the two bores 30, the flange has a recess 31 which is open outwards in the flange plane, that is to say in the separating surface, and which constitutes a further positive-locking element.

The FIG. 4 shows the subject of the FIG. 3 with additional fastening elements 32.1, 32.2. One side of the fastening element 32. 1 is realized as a counter flange to the flange 26. 1 of the first component 26. On this page, the fastener 32.1 n carries form-fitting elements 34, which are perfectly complementary to the n form-fitting elements 30 of the flange 26. In the present case, the interlocking elements of the mating flange 32.1 are cylindrical dowel pins 34, which fill the clear width of the holes 30 accurately. The position of the dowel pins is precisely defined in the separating surface, ie in the flange plane, and is subject only to manufacturing tolerances, but not to assembly tolerances. The fastening element 32.1 has, in the direction perpendicular to the flange plane, a material thickness which is greater than the material thickness of the flange 26.1 of the half shell or of the first component 26.1. The fastening element 32.1 represents a stable support for the half-shell-shaped first component 26.1. The accuracy of fit, with which the fastening element 32.1 and the half-shell-shaped first component are joined, is further increased by the fact that the fastening element 32.1 has a projection 33 has, which protrudes from its flange plane in the same direction as the dowel pins and which is designed such that it fills the outwardly open recess 31 in the flange of the half-shell-shaped first component 26.1. The projection 33 and the dowel pins 34 project out of the flange plane so far that they also penetrate holes and recesses in a flange of the mirror cover 18 and a flange of the second component 28. The material thickness of the projection 33 is preferably greater than the material thickness of the fastening element outside the projection.

This applies analogously to a second flange connection, which is opposite to the first flange connection described so far in the separating surface and which in particular has the second fastening element 32.2. The second flange connection is preferred, but not mandatory, constructed in mirror image to the first flange connection.

The FIG. 5 shows the subject of the FIG. 4 with additionally fitted mirror aperture 18. The mirror aperture 18 has a diaphragm section with an aperture edge 18.1 and two fastening sections 18.2, 18.3 and two spacers 18.4, 18.5 and is preferably rigid in itself. Preferably, the mirror panel 18 is a one-piece sheet metal part or plastic part. The fastening sections 18.2, 18.3 have a shape which is adapted to the flanges 26.1, 26.2 and are arranged on the mirror cover 18 such that in each case one fastening section 18.2 / 18.3 rests against one of the flanges 26.1 / 26.2 and covers the respective flange. In this case, the mounting portions have 18.2, 18.3 holes, which are arranged congruent to the holes 30 in the flanges 26.1, 26.2 and are the same size as these and have the same shape. The clear width of the holes is therefore also by the dowel pins 34 accurately filled.

By these features, the mirror aperture 18 is positioned on the first component 26 with a positional inaccuracy dominated by the manufacturing tolerance of the flanges, bores and dowel pins.

The fastening sections 18.2, 18.3 project beyond the flanges 26.1, 26.2 in the direction of the lens receptacle. These thus no longer the attachment of the mirror panel 18 serving parts of the mounting portions 18.2, 18.3 form spacers 18.4, 18.5, which improve the positional accuracy of the later used in the lens mount projection lens 16.

The FIG. 6 shows the subject of the FIG. 5 together with a projection lens 16 inserted into the lens receptacle of the first component 26. The lens receptacle 26 arranged on the lens-side end 24 of the first component 26 consists of channel sections 30 formed in the lens-side end 24. These are characterized by the shape and the dimension of their channel cross-section arranged to receive a coronary out of the edge of the projection lens 16 projecting projection 27 encompassing. As has been explained above, this can also be carried out in reverse, so that the projection lens has 16 recesses and the lens receptacle has complementary projections which fit precisely with it.

The spacers 18.4, 18.5 of the mirror panel 18 are so long that they touch the projection lens 16 inserted into the lens holder. The spacers are particularly preferably so long that they the projection lens 16 with a slight bias touch. A possibly without such spacers possibly existing game or possibly without such spacers possible positioning inaccuracy of the projection lens in the lens mount is limited by the touch. As a result, the inaccuracy of the color fringe influencing variables (distance projection lens - mirror aperture, focal length of the projection lens) is also dominated by manufacturing inaccuracies and still depends only to a minor extent on the assembly even in the touching contact.

The following again refers to those already described above FIG. 2 Reference is made, in particular, the second component 28 of the lens carrier 20 shows.

The second component 28 has two flanges 28.1, 28.2 with form-locking elements, which are dimensioned and arranged in mirror image to the flanges 26.1, 26.2 and form-locking elements of the first component 26. When assembling the first component 26 with the mirror panel 18, the fastening elements 32.1, 32.2 and the second half-shell-shaped component 28 thus stack of adjacent and formed by interlocking positive locking elements connected components are formed.

In the embodiment shown there, the second component 28 has at its end opposite the lens-side end 24 a base structure 29 for fastening a printed circuit board with semiconductor light sources and primary optics. The base structure 29 is here a part of the one-piece second component 28. The second component 28 and preferably also the first component preferably consists in each case of a good heat-conducting Material, in particular of metal. Such a part can be inexpensively manufactured by forming a sheet metal stamped part, which contributes to the manufacturing cost being as low as possible.

The semiconductor light sources are preferably arranged on a circuit board in thermal contact with the base structure. The base structure has a loose end 31, which is preferably designed so that it can be firmly connected by screws, rivet embossing or a cohesive connection technology with the light source side end of the first component 26. By means of this connection, a very high rigidity and mechanical strength of the lens carrier 20 serving as the central first holding structure 17 are achieved. It is understood that the base structure may also be a component of the first half-shell / of the first component 26 of the lens carrier. In one embodiment, the light source assembly, which in particular has at least the circuit board in addition to the light sources, is designed to be exchangeable. If a plurality of light source assemblies are used, for example for a low-beam component and a supplementary high-beam component, at least one of the two assemblies is preferably made replaceable.

Another great advantage of using a good heat conductor such as metal as the material of the lens carrier 20 is that the lens carrier 20 with its two half-shells 26, 28 itself can be used as a heat sink, since it by the thermal contact with the board heat from the chips of the Semiconductor light sources absorbs the heat well and can be discharged through its large surface to the ambient air. The life of semiconductor light sources is very much determined by their operating temperatures. By the in This design presented by means of half-shell-shaped components of the lens carrier, which are preferably made of sheet metal, the lens carrier 20 can either directly record the board with the semiconductor light sources or simply heat-conductively connected to a separate heat sink. The lens carrier 20 is thereby the heat sink and contributes in any case with the cooling. This has the advantage that the light module 10 either does not require a separate heat sink or that such a heat sink, if it should still be needed, can be smaller, lighter and thus more cost effective than in the prior art.

The following is again on the already partially described earlier FIG. 1 Referenced.

The FIG. 1 shows in particular the subject of the FIG. 2 together with light sources 12 and primary optics 14 in an assembled state. In particular, the dowel pins of the fastening elements also accurately fill the clear width of the bores of the second component 28 of the lens carrier. In addition, the second component 28 has, analogously to the first component 26, at least one positive-locking element which interacts with a complementary positive-locking element of the projection lens 16 in a precisely fitting manner.

The spacers of the mirror aperture 18 are dimensioned so that their length is sufficient to press the lens 18 with slight tension against the wall of the channel, so that the position of the projection lens in the direction of its optical axis with respect to the diaphragm edge of the mirror aperture 18 by the only dominated by manufacturing inaccuracies and by Mounting inaccuracies largely independent distance between the projection lens touching the leading edge of the spacers 18.4, 18.5 and the holes 30 and the dowel pins 34 is set.

After joining the first component 26, the second component 28, the fasteners 32.1, 32.2, the mirror aperture 18 and the projection lens 19, in which the projection lens 16 and the mirror aperture 18 between the half-shells, respectively components 28, 28 of the lens carrier 20 be, the components are firmly connected. The solid connection is preferably carried out by riveting, embossing, in particular hot stamping, or screwing the two components 26 and 28 or by a cohesive bonding method such as gluing. The dowel pins could serve as fasteners, for example, as rivets or studded studs.

The light source 12 preferably consists of an array of semiconductor light sources, which are attached together with associated primary optics 14 and a board 15 to one of the two components. When the light module is used as intended, the light source 12 is above the mirror aperture. As already mentioned, one (or more) supplementary light source (s) may also be located underneath the mirror cover when used as intended. FIG. 1 shows how the board 15 and the primary optics 14 are arranged on different sides of the also used as a heat sink material of the base structure 29, which protects the primary optics from undesired exposure to heat from the chips of the semiconductor light sources. The semiconductor light sources are arranged in recesses 29.1 of the basic structure. comparisons FIG. 2 , which square recesses 29.1 shows.

The FIG. 1 shows in particular the subject of the FIG. 6 together with the second component 28 of the lens carrier 20 and the board with semiconductor light sources and primary optics. The primary optics are preferably catadioptric transparent solids which collect the light emanating from the semiconductor light sources, focus them and direct them to the diaphragm edge of the mirror diaphragm. The resulting from the diaphragm edge intermediate light distribution is imaged by the projection lens in the apron of the projection light module.

FIG. 1 also shows that the fastening elements have a ball head, with which the entire projection light module is pivotable about an imaginary by the two ball heads pivot axis. In the FIG. 1 only one ball head 32.1 is visible, as the other is covered by the light module. In the example shown, the pivot axis runs parallel to a plane in which the diaphragm edge lies. It is therefore a pivot axis for a headlight range adjustment or headlight range control.

The ball heads represent an embodiment of second support structures that are set up to hold the light module in the headlight. The ball heads are preferably attached to the projections 33 or a cohesive component of the projections. 3
