Description

[0001] The invention relates to a light module, a method for operating a light module and a motor vehicle. State of the art

[0002] US 2020 / 0378576 A1 has disclosed a light module with a projection lens of special shape. A deflection optic is arranged at the side of the projection lens for forming a side light distribution.

[0003] EP2620697B1 discloses a module with laterally arranged light sources and refractive optics for a side light distribution.

[0004] According to US 2023 / 0093629 A1 a reflective component is used for the optics of a side illumination.

[0005] DE10140277A1 discloses two separate light modules for a main light distribution and a side light distribution. Summary

[0006] It is an object of the invention to provide a cheap light module with a main light distribution and a side light distribution.

[0007] This object is achieved by the features of claim 1.

[0008] According to the invention, a light module for a motor vehicle comprises:

[0009] at least one first semiconductor light source, at least one first auxiliary optic and at least one first projection optic for emitting a main light distribution, in particular a low beam distribution and / or a high beam distribution, which is emitted by the light module along an optical axis; and

[0010] at least one second semiconductor light source, at least one second auxiliary optic and at least one second projection optic for emitting a side light distribution, which is emitted by the light module offset from the optical axis.

[0011] The light module according to the invention allows to provide an extended side illumination when cornering and cornering driving of a motor vehicle. According to the invention, for realizing a side illumination in a headlight, it is not necessary to provide an additional light module which is only responsible for the side illumination.

[0012] In an advantageous manner, recourse can be had to the experience of existing light modules, which can be expanded by side lighting for cornering without the need for a separate light module to be newly developed and without the need for integration in other locations, for example in the bumper. This already existing light module expanded by side lighting can in particular be a single-function, dual-function or ADB dual-function light module. These light modules can be equipped with only very few additional components with a wider side lighting, for example for implementing or integrating additional functions, for example static cornering lights, cornering lights or fog lights. By expanding the functional scope of an existing module while keeping the number of components as identical as possible, an economically efficient functional expansion can be achieved. Depending on the design, the light module can be expanded to side lighting on both sides, i.e. on the left and on the right. Alternatively, one of the two sides, i.e. the left or the right, can be expanded by side lighting.

[0013] Furthermore, the manufacturing costs of the light module according to the application can be very low, since a separate light module for side lighting can be dispensed with. Since the "side light" function is integrated in the light module for the main light distribution, in particular the low beam, only a small number of components is required, so that a low cost can be maintained.

[0014] It can be provided in an advantageous manner that the main reflector foil portion is arranged at least sectionally between the at least one first auxiliary optics and the first projection optics. With this main reflector foil portion, different semiconductor light sources can be advantageously separated from one another to produce different light functions. For example, the main beam and / or the low beam can be separated from the cornering light. Furthermore, the matrix light function can be optically separated by means of the main reflector foil portion in order not to obscure standing persons and oncoming vehicles.

[0015] It can also be provided that the side reflector foil portion is arranged at least sectionally between the at least one second auxiliary optics and the second projection optics. Thus, the light of the "side light" can also be separated from the cornering light or other light functions.

[0016] In a cost-effective and compact manner, the main reflector foil portion and the side reflector foil portion can be provided by a common reflector foil member.

[0017] The second projection optics can advantageously be a deflection optics, which

[0018] is arranged laterally offset with respect to the optical axis, and

[0019] deflects the side light distribution in a direction transverse to the optical axis.

[0020] In this case, it can be provided that the main light distribution is coupled out at the exit surface of the first projection optics and the side light distribution intersects the main light distribution on one side of the exit surface.

[0021] Simple geometries can be created by using side reflector diaphragm sections.

[0022] -Located in a common plane with the diaphragm portion of the primary reflector, or

[0023] - Offset parallel to the diaphragm portion of the primary reflector.

[0024] It can be advantageously provided that the main light distribution is coupled out at the exit surface of the first projection optics, and the side light distribution intersects with the main light distribution on one side of the exit surface.

[0025] It can be advantageously provided that two semiconductor light sources are mounted on a common printed circuit board.

[0026] It can be advantageously provided that the printed circuit board is coupled to a heat sink extending along the direction of the printed circuit board, thereby overlapping with and dissipating heat from the two semiconductor light sources.

[0027] Advantageously, the first auxiliary optics has patterned repeating shaped elements connected together and each having its own semiconductor light source and its own optical axis, and the second auxiliary optics includes at least one other shaped element having a second semiconductor light source, wherein the optical axis of the shaped element of the second auxiliary optics is not parallel to the optical axis of the shaped element of the first auxiliary optics.

[0028] It can be advantageously provided that another forming element having a second semiconductor light source is separate from the forming element of the first auxiliary optics.

[0029] It can be advantageously provided that the deflecting optics are reflective optics made of a different material than the first projection optics and are arranged laterally, particularly on both sides of the first projection optics.

[0030] Alternatively, the deflecting optics can be integrated with the first projection optics. The deflecting optics can also be arranged laterally, particularly on both sides of the first projection optics.

[0031] This invention also relates to a method for operating an optical module. The method comprises the following steps:

[0032] -The main light distribution is coupled out from the first auxiliary optics.

[0033] - Planar collimated light distribution parallel to the primary reflector diaphragm portion

[0034] - The main light distribution is coupled into and out of the first projection optics respectively.

[0035] - The side light distribution is coupled out from the second auxiliary optics, and

[0036] - Deflect the side light distribution in a direction transverse to the optical axis.

[0037] The present invention also relates to a motor vehicle having two optical modules. The first optical module is disposed on the left side of the front of the motor vehicle, while the second optical module is disposed on the right side of the front of the motor vehicle.

[0038] In the attached diagram:

[0049] Figure 10b Detailed information from Figure 10a The side lighting distribution, where possible focal lengths are shown, and

[0050] Figure 11 It shows Figure 10a and 10b Side light distribution;

[0051] Figure 12 The figure shows components within one of the optical modules in the fourth embodiment, wherein a side light distribution is provided.

[0052] Figure 1 A motor vehicle 2 with two optical modules 4 and 6 is shown. The first optical module 4 is located on the left side of the front of the motor vehicle 2. The second optical module 6 is located on the right side of the front of the motor vehicle 2. The two optical modules 4 and 6 each have an optical cone 8 or 10, which each has a main light distribution 12.

[0053] Motor vehicle 2 can turn right or left via its steerable wheels. In this respect, motor vehicle 2 can turn right or left. Before and during the turn, the two light modules 4 and 6 illuminate the road and adjacent areas, such as sidewalks, houses, trees, and grass, respectively, using sidelight distributions 14a, 14b or 16a, 16b. The brightness of the sidelight distributions 14a, 14b, 16a, 16b is lower than that of the main light distribution 12. In the horizontal plane of motor vehicle 2 and light modules 4 and 6, the two portions of the sidelight distributions 14a, 14b or the same two portions of the sidelight distributions 16a, 16b are opened at an angle much larger than the light cone 8 or 10 of the main light distribution 12 or 10. In this respect, each of the two light modules 4 and 6 is extended on both sides—that is, the left and right sides—by side lighting 14a or 14b or 16a or 16b.

[0054] However, in an alternative embodiment not shown in the figure, each optical module 4 or 6 can only illuminate the outside through side light distributions 14a or 16a. That is, in this case, only the side light distribution 16a of the right optical module 6 emits to the right. Conversely, in the case of the left optical module 4, only its side light distribution 14a emits to the left.

[0055] The two optical modules 4 and 6 have the same design. That is, the two optical modules 4 and 6 are mirror images of each other with respect to the vertical longitudinal plane of the vehicle.

[0056] Optical modules 4 and 6 each have a housing 18, which is enclosed on the outside of the motor vehicle 2 by a transparent cover 20. The main light distribution 12 and the side light distributions 14a, 14b or 16a, 16b pass through the cover 20 respectively.

[0057] The following reference Figures 2 to 8 Explain one of the two optical modules 4 and 6, optical module 4. This optical module 4 is shown in both embodiments.

[0058] Figure 2 and Figure 3 The diagram shows the arrangement of the two structures respectively. Figure 1 or Figure 12 A component of a first embodiment of an optical module 4 within a housing 18.

[0059] The components within the housing 18 of the optical module 4 include:

[0060] - A first auxiliary optical device 22 from which a main light distribution 12 of a plurality of first semiconductor light sources 26 emits light;

[0061] -Reflector diaphragm component 28, which extends substantially in a plane located in the drawing plane;

[0062] - A first projection optics 30, wherein a main light distribution 12 is coupled into and out of the first projection optics 30; wherein the optical axis 32 of the projection optics 30 is parallel to the plane of the reflector diaphragm member 28.

[0063] - Two second auxiliary optical devices 34 having two second semiconductor light sources 36, from which side light distributions 14a, 14b are emitted;

[0064] - The second projection optics 37 includes two deflection optics 38.

[0065] -Adjusted laterally relative to the optical axis 32, and

[0066] -It deflects the side light distribution 14a, 14b in the direction transverse to the optical axis 32.

[0067] The first semiconductor light source 26 and the second semiconductor light source 36 are preferably surface-mount light-emitting diodes (LEDs). The first semiconductor light source 26 with main light distribution 12 and the second semiconductor light source 36 with side light distributions 14a, 14b are mounted only on the surface-mount ... Figure 3 The front side of the common printed circuit board 40 shown in the diagram. The front side is also called the PCBA layer, where "PCB" stands for the technical term "printed circuit board".

[0068] A heat sink 41 is coupled to the back of the printed circuit board 40, which extends in the direction of the printed circuit board 40 and overlaps with the first semiconductor light source 26 and the second semiconductor light source 36, thereby removing heat generated during the operation of all these semiconductor light sources 26, 36.

[0069] Figure 1 The main light distribution 12 and side light distributions 14a, 14b shown are generated in the intermediate image plane by means of semiconductor light sources 26, 36 via first and second auxiliary optics 22, 34 (also referred to as main optics 24). The main optics 24 are specifically reflective optics, designed as TIR optics. TIR is an abbreviation for the term "total internal reflection," meaning that light is completely reflected at the interface between two media. In this respect, contrary to the accompanying drawings, the semiconductor light sources 26, 36 may also...

[0070] Arranged above the attached drawing plane, and

[0071] It emits in the direction of the reflector diaphragm member 28, and

[0072] The prism-shaped main optical device 24 preferably reflects the light distribution emitted by the semiconductor light sources 26 and 36 at a 90° angle, so that the collimated light distribution parallel to the reflector diaphragm member 28 is then emitted and coupled into the first projection optical device 30 in the direction toward it.

[0073] The main light distribution 12 generated by the auxiliary optics 22 is guided by the auxiliary optics 22 along the reflector diaphragm member 28, which is designed as a mirror diaphragm and arranged between the first auxiliary optics 22 and the first projection optics 30 for this purpose.

[0074] The reflector diaphragm member 28 has a main reflector diaphragm portion 27 with a concave edge 48. The main reflector diaphragm portion 27 forms the central portion of the reflector diaphragm member 28. However, the main reflector diaphragm portion 27 does not necessarily have to be located in the center. In particular, if, contrary to the embodiment, only the right or left side light distribution 14a or 14b is provided, the main reflector diaphragm portion 27 does not necessarily need to be located in the center, but may also form the side portion of the reflector diaphragm member 28.

[0075] The main light distribution 12 is coupled into the projection lens 44 of the projection optics 30. The light coupled therein is refracted by the projection lens 44. The maximum possible angle of the light cone 8 or 10 of the corresponding projection lens 44 is technically limited by the total internal reflection effect. Therefore, it is physically impossible to simultaneously generate low beam headlights and turn signals with a single projection lens 44. However, this disadvantageously prevents side illumination when turning.

[0076] The first auxiliary optical device 22 is a single unit and has multiple shaped elements that are transparent to visible light and repeat in a pattern. Each of these patterned shaped elements has its own light source 26 and its own optical axis 50. These optical axes 50 are slightly tilted in the direction toward the optical axis 32 of the projection lens 44.

[0077] Each of the two second auxiliary optics 34 also has multiple shaping elements that are transparent to visible light. In this case, each of the two second auxiliary optics 34 has fewer shaping elements than the first auxiliary optics 22.

[0078] Each forming element of the two second auxiliary optics 34 has its own second semiconductor light source 36. In the mounting position, one second auxiliary optics 34 is arranged to the left of the first auxiliary optics 22, while the other second auxiliary optics 34 is arranged to the right of the first auxiliary optics 22. The forming elements of the second auxiliary optics 34 also have an optical axis 52 that is slightly tilted in the direction of the optical axis 32 of the projection lens 44, such that each of the two side light distributions 14a, 14b points to one of the two deflecting optics 38.

[0079] The forming element of the second auxiliary optical device 34 can be separated from the forming element of the first auxiliary optical device 22. However, alternatively, the forming element of the second auxiliary optical device 34 can also be formed integrally with the forming element of the first auxiliary optical device 22.

[0080] Side reflector diaphragm portions 54 are arranged on both sides and sides of the main reflector diaphragm portion 27, and together with the main reflector diaphragm portion 27, they provide reflector diaphragm components 28.

[0081] The deflecting optics 38 is a reflective optics made of a different material than the projection optics 30. The reflective optics consists of two parts, arranged laterally on the left and right sides of the projection optics 30.

[0082] Compared to optical modules without side light distribution, or compared to the optical modules of the second embodiment explained below, this reflective optics is indeed an additional component. However, a projection lens holder that also holds the projection lens 44 can be used in a cost-effective manner to position the reflective optics.

[0083] The side light distributions 14a and 14b are not coupled into the projection lens 44, but are deflected by the deflecting optics 38 and guided through the projection lens 44. In this case, the side light distributions 14a and 14b intersect with the main light distribution 12 on one side of the exit surface 42. In this case, the side light distributions 14a and 14b are spaced apart from the exit surface 42.

[0084] Conversely, for clarity, the principal light distribution 12 is not in... Figure 3 As shown in the text, but in Figure 4 As shown in the figure, the main light distribution 12 is coupled out at the exit surface 42 of the projection lens 44.

[0085] Figure 5 The side light distributions 14a and 14b shown extend the main light distribution 12. Figure 6 The overall light distribution shown is wider (58).

[0086] Figure 7 and Figure 8A second embodiment of an optical module 4 is shown, showing components arranged within the housing 18 of the optical module 4. The differences from the first embodiment are discussed below. Otherwise, the interpretation of the first embodiment applies, including the alternatives mentioned in the first embodiment.

[0087] In the second embodiment, the deflection optics 138 and the projection lens 144 are integrated.

[0088] To allow for this monolithic or use-of-the-material approach, the deflecting optics 138 comprises a refractive surface. This refractive surface refracts light and can be configured with microstructures. The refractive surface is mathematically independent of the central projection lens 144.

[0089] Figures 9 to 12 Third and fourth embodiments of the optical module 4 are shown. In both embodiments, cost and design advantages relative to a single module are achieved by using a common PCB for all functions. The side light distribution and main light distribution are cooled by a common heat sink disposed on the rear side of the PCB and overlapping both the first semiconductor light source 226 and the second semiconductor light source 236. Furthermore, in the optical module of the third and fourth embodiments, in each case, a...

[0093] (Not shown in more detail in the figure).

[0094] Figure 9 Figures 10 and 10 show components for a third embodiment of an optical module, arranged within the housing of the optical module.

[0095] The additional semiconductor light source 236 required for the side light distribution is placed on the front side of the common printed circuit board together with the first auxiliary optics 222 for the high beam and / or low beam.

[0096] The first auxiliary optical device 222 is extended by the side light distribution.

[0097] In this third embodiment, the optical module features a remarkably thin and cost-effective design. The optical module is designed as a low-profile module because the first auxiliary optics 222 is designed as a solid-body optics device. In this "solid-body optics" design, the TIR collimator is integrally connected by a transparent flat light guide 253, whose exit surface 255 is convex. In an alternative embodiment, a prism that deflects the light from the semiconductor light source by 90° can be integrated into the solid body.

[0098] Light emitted by the first semiconductor light source 226 is guided by the TIR collimator of the first auxiliary optics 222 into its light guide 253. A light distribution to be imaged is generated in the region at the edge of the mirror film located within the light guide 253. This light distribution is imaged as the main light distribution on the road ahead of the vehicle by the lenticular exit surface 255 of the projection optics 230 and the projection lens 244. For this purpose, the projection lens 244 has a curved or flat incident surface 256 and a convex curved exit surface 257. In this respect, the main light distribution, i.e., particularly the low beam distribution and / or high beam distribution, is emitted by the light module along the optical axis 232 via the projection lens 244.

[0099] A second auxiliary optics 237, with a side-light distribution, is arranged on the side of the first auxiliary optics 222. This second auxiliary optics 237 is also implemented as a TIR collimator, which is physically separate from the TIR collimator of the first auxiliary optics 222. In an alternative embodiment not shown in the figures, the two auxiliary optics 222 and 237 are connected to each other as a single unit.

[0100] An array is arranged on the side of the optical guide 253.

[0101] -Optical surface 264 or mirror film 258 and

[0102] -Optical surface 265 or first lens 259

[0103] The first lens 259 and its associated optical surface 265 are part of the auxiliary optics 237. The second lens 260 has an incident surface 261 and an exit surface 262. The incident surface 261 and exit surface 262 of the second lens 260 are connected to the projection lens 244. This connection can be a single unit or achieved through separately prefabricated components that are bonded, welded, solvent-welded, etc., to each other. The second lens 260 may overlap with the edge of the first projection optics 230.

[0104] In this respect, the projection lens 244 is provided with optical surfaces. These optical surfaces are the incident surface 261 and the exit surface 262 of the second lens 260. Therefore, the incident surface 261 and the exit surface 262 are firmly attached to the projection lens 244 to form a component. This component may preferably be made of polymethyl methacrylate (PMMA).

[0106] -First lens 259 or optical surface 265

[0107] - Mirror film 258 or optical surface 264 and

[0108] -TIR Collimator 263

[0109] Preferably, it is integrally manufactured with or fixedly connected to the first auxiliary optics 222 to form a component. This component may preferably be made of polycarbonate (PC). Therefore, on this component,

[0110] -First lens 259 or optical surface 265

[0111] - Mirror film 258 or optical surface 264 and

[0112] -TIR collimator 263 of the second auxiliary optical device 237

[0113] Represented by optical surfaces 263, 264, and 265 on the component.

[0114] Figure 10a The resulting beam path 270 for the light distribution of a turn signal or side lighting distribution is shown. Furthermore, the optical functions of the various optical surfaces 261, 262, 263, 264, 265, 237, 258, and 259 for side lighting distribution to achieve the turn signal are shown. Surface 265 of the first lens 259 images the real focal point F1 located in the diaphragm plane of the mirror diaphragm 264 onto a virtual focal point F2 located on the optical axis 266, which is tilted relative to the optical axis 232 or the main emission direction 200 in the direction of travel. Then, the incident surface 261 of the second lens 260 images the virtual focal point F2 onto another virtual intermediate focal point F3 located on the optical axis 267, which is also tilted relative to the optical axis 232 or the main emission direction 200 in the direction of travel. However, the optical axis 267 is more inclined towards the optical axis 232 than the optical axis 266. In this case, the term "more inclined" means that the angle β between axes 267 and 232 is greater than the angle α between axes 266 and 232. The resulting image is produced by the exit surface 262 of the second lens 260, which images the virtual focal point F3 onto a focal point F4 located at a distance of 25 m. This focal point F4 is located on the optical axis 268, forming an angle δ of at least 25°, preferably about 30°, with the optical axis 232. In this regard, the following formula applies to angles: δ > β > α.

[0115] Figure 10b The focal lengths |F1|, |F2|, |F3|, and |F4| that are advantageous for the focal points F1, F2, F3, and F4 are shown. Regions where angles α, β, and δ can be advantageously presented are also described. Angles α, β, and δ describe the position of the optical axis relative to the principal emission direction. Furthermore, preferred angular dimensions are shown.

[0116] The focal length |F1| of a real focal point F1 is advantageously located at approximately 25mm. Twice the focal length |F1| is less than or equal to the focal length |F2|. The focal length |F2| is less than or equal to the focal length |F3|.

[0117] The focal length |F3| is much smaller than the focal length |F4|, with a focal length of approximately 25 m.

[0118] The angle α is in the range of 5° and 15°. The preferred angle α is 10°.

[0119] The angle β is in the range of 15° and 25°. The preferred angle β is 20°.

[0120] The angle δ is greater than 25°. The preferred angle δ is 30°.

[0121] Figure 11 The side light distribution 100 of the turn signal generated by the light module of the third embodiment is shown. In the third embodiment of the light module mounted on the left side of the vehicle, the 1 lux line 100a is horizontally below -70°.

[0122] Figure 12 The housing 18 of the left-side optical module 4 in the fourth embodiment is shown, which itself does not have a side light distribution. Furthermore, the housing extension portion 300 is shown in dashed lines, through which the housing 18 is extended by the side light distribution. Within the housing extension portion 300, the side light distribution 101 is divided into two light distributions 101a and 101b.

[0123] The optical module 4 is shown in a vertical cross-section. In this vertical cross-section, the outline of the exit surface 362 of the second lens 360 is shown.

[0124] The exit surface 357 of the projection lens 344 is seamlessly adjacent to it. In addition to the auxiliary optics 470 provided for the side light distribution 101, another auxiliary optics 471 is provided. Both auxiliary optics 470 and 471 are each designed as TIR collimators. Figure 12 As can be seen from the lower part, compared with the first to third embodiments, the entire side light distribution 101 is extended in the width of the horizontal illumination. Therefore, compared with the first to third embodiments, in addition to the light distribution 101a, an additional light distribution 101b is provided, which can be turned on or off as needed, so that the horizontal illumination can be extended in two stages by the turn signal.
