Definitions
- the invention relates to a lighting module for a motor vehicle, in particular projection module for a motor vehicle, comprising at least one lighting unit and a lens, preferably a projection lens, wherein the radiated from the at least one lighting unit to the lens light from the lens - in the installed state of the lighting module - in a projected in front of the motor vehicle area is projected.
- the invention relates to a vehicle headlamp with at least one such lighting module.
- illumination module With such an illumination module, light from the at least one illumination unit is deflected by a lens arranged at the front of the illumination module in the forward direction of the illumination module and emitted to the roadway, where there is a defined light distribution pattern, such as a low beam distribution or a high beam distribution, a daytime driving etc. forms.
- the light distribution is significantly influenced by the design of the lens used in such projection systems.
- aberrations are inevitable with spherical lenses. Accordingly, in order to at least partially correct such lens aberrations, aspheric lenses are used. As a rule, a compromise must always be found on which aberrations are (more) corrected in favor of other aberrations.
- the lens is subdivided into two or more lens areas, and in each lens area light is radiated only from a defined area of the at least one illumination unit assigned to the lens area and / or into each Lens area only light, which exits at certain angles of radiation from the illumination unit, is irradiated, and / or light is irradiated only from at least one of the lens area associated lighting unit.
- each lens area is designed according to a calculation rule, and wherein at least two lens areas of the lens differ from one another with regard to their calculation rule.
- the lens By dividing the lens into two or more lens areas which differ from one another as described above, it becomes possible, for example, to correct one aberration, such as a color aberration, with one lens area, while controlling the sharpness of the image over another lens area.
- one aberration such as a color aberration
- a specific lens area assumes a specific task; but of course it can also be provided that two or more lens areas are provided for a specific task, such as the correction of a color aberration.
- Headlamps are usually designed, for example, according to the ECE regulation for image removal (distance of the image plane) of 25 meters.
- Other regulations for example in the USA (SAE regulation), however, for example, provide a width of 10 meters, for which a headlight has to be designed.
- SAE regulation for example, provide a width of 10 meters, for which a headlight has to be designed.
- At least two lens areas differ with regard to the calculation rules on which they are based in at least one of the above-mentioned parameters, which flows into the respective calculation rule.
- the division into lens areas can be effected on the light entry surface of the lens, or the division into lens areas takes place on the light exit surface of the lens.
- the light entry surface is flat over all regions, while the light exit surface has a different curvature, depending on the lens region, etc.
- the individual lens regions of the lens differ from one another both on the light entry surface and the light exit surface.
- transition between two adjacent regions at the light entry surface and / or the light exit surface is continuous. This results in a flowing, smooth transition, which is aesthetically pleasing, which can be particularly advantageous for the lens outside. In addition, such a surface is easy to manufacture.
- transition between two adjacent regions at the light entry surface and / or the light exit surface is unsteady, for example in the shape of a staircase.
- Such transitions are easier to calculate and the individual lens areas are practically completely decoupled from each other, ie each lens area contributes clearly and exclusively to a particular design goal.
- the range limits are obviously recognizable in such a case, but may occur at the stages unwanted stray light or the steps can be perceived as visually less appealing.
- any combinations e.g. continuous transition (continuous transitions) on one side, unsteady transition or unsteady transitions on the other side or even continuous transition between two areas on one side and unsteady transition between two other areas on the same side etc. possible.
- the lens is divided into two, three or four lens areas.
- the individual parameters that are included in a calculation rule can be constant for each lens area. However, it can also be provided that one, several or all parameters of a calculation rule for a lens area vary as a function of the considered position of the lens area.
- the considered lens area is computationally composed of a multiplicity of smaller lens subareas, for example of several hundred such subregions, which then form the lens area when combined.
- variable over a lens area variable parameters change continuously, for example, linear, square, sigmoid, etc.
- a lens according to the invention can be exploited if it is further provided that defined light emission regions of a lighting unit emit light only in a defined, assigned lens region or in two or more defined, assigned lens regions of the lens. In this way, the lighting unit and the lens or the mutually associated areas can be optimally matched to one another.
- each illumination unit emitting light only in at least one, two or more lens areas, preferably exactly one defined lens area of the lens. In any case, it is favorable if the light emission regions of a lighting unit and / or the various lighting units can be controlled separately.
- the at least one illumination unit comprises at least one reflector and at least one light source associated with the at least one reflector.
- the (different) light emission regions are formed by the reflective surface (s) of the one or more reflectors, and / or by two or more such lighting units.
- the lighting unit comprises at least one light source, which feeds light into at least one light guide.
- the light emission surface of the at least one light guide is subdivided into two or more emission regions, and light from an emission region is emitted in each case only into one or more defined, assigned lens regions.

- FIG. 6 shows light distributions generated by a lighting device according to FIG. 3, FIG.
- FIG. 7 shows a further illumination device according to the invention in a horizontal section
- Fig. 8 shows the lens of Figure 7 in a perspective view from the front
- FIG. 9 shows a lens according to the invention with different object planes.
- FIG. 1 shows a lighting module, specifically an LED bi-function projection module 1, which comprises a lighting device 2 and a lens 3.
- the lighting device 2 consists of an upper reflector 20 which is associated with a light source 22 in the form of one or more LEDs (reflector 20 and light source 22 form the upper illumination unit 2a), and from a lower reflector 21 with a light source 23, also in shape of one or more LEDs (reflector 21 and light source 23 form a second, lower illumination unit).
- the two light sources 22, 23 are preferably controlled separately.
- the light sources 22, 23 lie substantially at a focal point of the associated reflector 20, 21.
- the focal plane of the lens 3 extends approximately or exactly through the second focal points of the two reflectors 20, 21.
- a (in this case, rigid) horizontal aperture 24 is provided, the optically effective edge of which faces the lens 3 in order to produce a light-dark boundary.
- a low-beam light distribution LVb can thus be generated as shown in FIG. 1a, a lower illumination unit 2b generates a part LVa of a high-beam distribution, the total light distribution (FIG. overall high beam distribution) with activated upper and lower illumination unit is designated LV.
- a lens 30 modified with respect to the lens 3 is used.
- the lens 30 has two lens portions 30a, 30b, the lower lens portion 30b corresponding to the lower portion of the lens 3 (the portion underlying the optical axis X of the module) of FIG.
- the upper lens area 30a is tilted in the direction of the illumination units 2 in relation to the "original" lens contour of the lens 3.
- the light entrance surface 30a 'also tilted against the optical axis X is "parallelized" to the plane light entrance surface of the lens area 30b. ie, that the light entry surface is a continuous plane which is preferably normal to the axis X.
- the upper half of the lens thus looks purely formal, as if its axis were shifted parallel downwards and its center thickness would have been slightly increased.
- the lens regions differ in only at the light exit surface, wherein the two lens regions 30a, 30b at the light exit surface, for example, as shown, discontinuously merge into one another.
- a discontinuous transition provides the best land use, but is more difficult to produce.
- a "rounded", steady transition, however, is better producible, but may lead to stray light.
- the lens 30 corresponds to an asphere as the lens 3 of Figure 1, these form a light distribution LVb 'as shown in Figure 2a, which corresponds in shape and position of the light distribution LVb of Figure la.
- the lens area 30a is optimized such that the further up a light beam passes through the lens area 30a, the more the light rays are refracted downward. Thereby, the light distribution LVa 'generated via the upper lens area 30a becomes shifted down, whereby the gap S of Figure la closes, as shown in Figure 2a, so that there is a closed (far) light distribution LV.
- the lower illumination unit 2b uses only a specific area of the lens 30 for generating the high beam distribution, preferably only the upper area 30a.
- Light from the upper illumination unit 2a can in principle pass through the entire lens 30, but preferably the dipped beam passes through other regions of the lens (namely through the lower portion 30b) than the high beam.
- the two lens regions 30a, 30b are thus preferably illuminated in each case by their own illumination unit 2a, 2b assigned to the respective lens region 30a, 30b, wherein preferably each illumination unit 2a, 2b radiates light precisely only in the lens region 30a, 30b assigned to it.
- the lens 30 from FIG. 2 thus has two different lens areas 30a, 30b, which have different imaging properties and are based, for example, on different calculation rules, that is to say were determined, for example, by means of different calculation rules.
- the two calculation rules differ in the parameter that the "optical axis" of the region 30a was tilted relative to the module axis X (see FIG. 2b, tilting by angle ot), while the optical axis of the lower region 30b remains parallel to the axis X. Accordingly, the resulting lens 30 no longer has a unique optical axis.
- the optical axis of the region 30a is tilted by approximately 1.3 [deg.] Relative to the module axis X, as sketched in FIG. 2b.
- FIG. 2 b illustrates the process of how the upper region 30 a of the lens 30 is calculated / generated. It starts from a lens 3 of Figure 1 (left lens in Figure 2b) and tilts them by the angle ot. This results in the right-hand tilted lens in FIG. 2b, whose region lying above the axis X forms the contour of the light exit surface of the lens 30.
- the light entrance surface of the upper area is tilted against the axis X at an angle not equal to 90 °. This light entry surface is "straightened" (computationally or in the future).
- the resulting lens 30 results in a continuous plane light entry surface as already described above.
- this is equivalent to a displacement of the lens axis parallel to the bottom and a slight increase in the center thickness.
- FIG. 3 shows a further illumination module 1 according to the invention with a lighting unit 2 comprising a reflector 200 and a light source 201.
- the optical axis of the module 1 is designated by X.
- Light from the illumination unit 2 is projected by a lens 300 on the roadway in front of the vehicle.
- Aperture 202 is provided to form a cut-off line, the upper edge of which is imaged in the light image as a cut-off line.
- the lens 300 has two partial areas 300a, 300b which follow different calculation rules, the two partial areas 300a, 300b having different focal lengths as different parameters.
- the lens area 300b has a magnification of approximately 0.85 ° / mm, while in the area 300a a magnification of approximately 1.05 ° / mm is achieved.
- the position of the focal point F coincides for the two partial areas 300a, 300b, and the light source 201 is arranged approximately at this focal point.
- the sub-area 300b (rays Sb), which has the larger focal length BWb, provides, for example, a sharp high beam maximum (narrow light beam, bright maximum) in the area HV and a good mapping in the area of asymmetry.
- the partial area 300a with a smaller focal length BWa provides a uniform apron illumination and a large width of the light distribution LV1 (rays Sa).
- a further subarea 300c can be provided, with which an additional light function can be realized, for example for generating an overhead light distribution LV2, as shown in FIG.
- the light exit surface is tilted more towards the light source so that the exiting light rays are refracted more strongly upwards (light rays Sc).
- the lens region 300c differs from the other two lens regions 300a, 300b by a different focal length, a changed position of the axis, which may be inclined to the axis X of the system, and it is also possible or may be advantageous if these parameters via the lens area 300c, as described above.
- the individual subregions continuously merge into one another.
- the lens region 300b', 300b" with a larger focal length is also at the light exit surface of FIG each lens by a gradation, which, however, is generally much smaller than those at the light entrance surface, separated from the other sub-areas.
- an illumination module as shown in FIG. 3, it is particularly advantageous if certain areas of the illumination unit 2 emit light only in specific subareas 300a, 300b, 300c of the lens 300.
- the upper region 200a of the reflector 200 radiates light only onto the partial regions 300a, 300b of the lens 300, while the lower region 200b of the reflector 200 emits light only in the partial region 300c of the lens 300 for producing an additional light function (for example as shown below the shutter assembly).
- the light source 201 is preferably a light source which can be switched on and off in segments or regions, preferably also dimmable. Particularly suitable for this purpose is a light source which consists of a plurality of light emitting diodes (LEDs), which can each be controlled individually or in groups. In this way, each of the lighting functions can be activated or deactivated independently of the others.
- LEDs light emitting diodes
- Figure 7 shows a still further variant, this time in a horizontal section.
- the illumination unit 2000 consists of a light source 2001, which feeds light into a light guide 2002, from which the light exits via the light exit surface 2002a and is emitted to a lens 3000, from which the light in the form of a desired light distribution an area is projected in front of the vehicle.
- a lighting unit 2000 is a surface radiator, of which an exemplary embodiment is shown in FIG.
- a light source as shown in Figure 7 is also suitable, if appropriately adapted for use in one of the previously described variants, and likewise a light source as in the previously described variants can be used for the module of Figure 7.
- the light sources respectively shown in the figures represent the respectively optimal variant of a lighting unit for the lighting module shown there.
- the lens used in Figure 7 and shown in a perspective view in Figure 8 is based on a so-called torus lens.
- torus lens When using pure torus lenses compact lighting modules can be realized, which can produce light distribution with large width.
- toroidal surfaces are poorly suited for imaging the asymmetry in a low-beam distribution, since horizontal and vertical edges are imaged differently sharply.
- a central subregion 3000b which consists of a rotationally symmetric asphere, is supplemented by toroidal subregions 3000a at the edge. Both on the inside of the lens and on the outside of the lens, this results in stepped transitions between the subregions 3000a and 3000b.
- the lens has similar parameters (e.g., magnification) in both areas 3000a and 3000b, in order to minimize the height of the steps between the areas.
- magnification e.g., magnification
- the imaging scale in the region 3000b of the asphere is approximately 1.6 ° / mm in both the horizontal and vertical directions.
- magnification is also approximately 1.6 ° / mm.
- the magnification is larger in the torus areas 3000a than in the area 3000b and, in the above example, the magnification (horizontal) is> 3 ° / mm.
- the light entry surface is illuminated almost evenly.
- the light is "blurred” laterally in the regions 3000a, ie in the horizontal direction (as shown in FIG. 7 by means of the light rays St, St '), that is, with the regions 3000a
- the exact passage point of the light rays through the object plane of the lens is of subordinate importance.
- Light projected onto the road surface by the central area 3000b maps the asymmetrical bend of the light exit surface 2002a of the light guide 2002 or an aperture (not shown) in the beam path in a known manner for this purpose.
- the lens 3000 shown here a (very) wide light distribution can be generated while at the same time providing a good image of the light-dark boundary in the HV range in the light image, wherein the lens has only a small thickness and small dimensions.
- the illumination unit 2000 is preferably matched to the lens, in particular to the toroidal areas 3000a, so that the light distribution generated by the individual areas 3000a, 3000b of the lens 3000 in the far field is as seamless as possible, so that a homogeneous light pattern results .
- the tuning takes place in such a way that light rays which pass through the toroidal region 3000a in the vicinity of the central region 3000b (ray St ') run approximately or exactly parallel to the neighboring rays (Sr') through central region 3000b.
- rays from any point of the light exit surface 2002a of the area radiator 2000 impinge on all lens areas 3000a, 3000b of the lens 3000.
- the distance of the light exit surface 2002a to the lens 3000 and / or the geometry of the lens 3000 are, however, chosen such that in the central lens region 3000b only light which emerges from the light exit surface 2002a under a main emission direction enters this lens region 3000b, while in FIG the lens areas 3000a only passes light which is emitted in a secondary emission direction.
- the central area 3000b is thus supplied with significantly more light than the edge areas 3000a.
- the angle range for the secondary beam direction moves from a lower limit (40 °, 10 °, 30 °) up to an upper limit, which is typically between 45 ° and 65 °, preferably about 50 °.
- the light exit surface 2002a has a normal distance to the rear, facing surface of the lens region 3000b of approximately 13 mm.
- the width of this lens region 3000b, in particular the surface facing the light exit surface 2002a, i. the horizontal extension of this lens region (measured in a horizontal section in which the optical axis X lies) is approximately 9.7 mm-9.8 mm, specifically approximately 9.74 mm.
- the height of the lens is about 18.3 mm and the two lens sections 3000a have a width of about 5 mm - 5.1 mm.
- the main emission direction extends in this example on both sides of the optical axis X from 0 ° - about 20.35 ° and the Mauabstrahlutter thereon on both sides then from about 20.35 ° - about 43.6 °.
- FIG. 9 shows yet another example in which one lens 4000 has two regions 4000a, 4000b which, with regard to the position of the object plane (object-side focal plane), i. the distance of the object plane of the respective lens area 4000a, 4000b differ.
- the lens 4000 has in its lying below the axis of symmetry X area 4000b at the light exit surface less curvature than a symmetrical to the axis X lens 4000 '.
- the object-side focal plane Bu for rays passing through the lower region 4000b through the lens 4000 has a greater distance from the region 4000b than the object-side focal plane Bo for rays passing through the upper region 4000a through the lens 4000 occur.
- the actual object somewhat an aperture BL with a top edge, which is depicted as a light-dark boundary, then lies between these two object planes Bo, Bu.
- the invention makes it possible to realize a lighting module or a vehicle headlight with at least one such module, with which legal regulations, such as ECE, SAE, CCC, etc. can be met.
