Description

Technical Field

[0001] The invention relates to a lighting device for a vehicle, in particular a motor vehicle. Background Art

[0002] Illuminating devices with a plurality of light sources and a primary optical element for guiding the individual light distributions emitted by the light sources are known from the prior art. Thus, for example, DE 10 2016 124 800 A1 discloses such an illuminating device.

[0003] A disadvantage here is that the primary optical element can deform, in particular due to temperature fluctuations, thereby negatively affecting the coupling-in or coupling-out properties and / or parameters of the primary optical element, such as the distance between the light source and the primary optical element or its coupling-in surface. Summary of the invention

[0004] It is therefore an object of the present invention to provide a lighting device in which the above-mentioned disadvantages are eliminated or at least reduced.

[0005] This object is achieved by a lighting device for a vehicle, in particular a motor vehicle, having the features of the invention.

[0006] The lighting device comprises a plurality of light sources for generating respective single light distributions and at least one primary optical element having a body. The body comprises a plurality of light incident surfaces for coupling the single light distributions generated by the light sources into the body. The body comprises a light exit surface for coupling the coupled single light distributions out of the body along a main emission direction. The lighting device comprises at least one carrier element for receiving the primary optical element and at least one fastening element for fastening the primary optical element to the carrier element.

[0007] The carrier element has at least one fastening continuation. The primary optical element has a fastening section. The fastening section is designed to receive the fastening continuation. It is also conceivable that the fastening continuation can be designed to receive the fastening section. The fastening section of the primary optical element is arranged, in particular clamped, between the fastening element and the fastening continuation of the carrier element. The fastening section of the primary optical element can be pressed onto the fastening continuation of the carrier element by means of the fastening element.

[0008] The fastening section is used in particular for fastening the primary optical element. In other words, the primary optical element can be fastened or fixed by means of the fastening section. The primary optical element can be fastened or fixed by clamping or tensioning the fastening section of the primary optical element between the fastening element and the fastening continuation of the carrier element. In this case, the fastening section of the primary optical element is in particular contacted by the fastening element (on the one hand) and by the fastening continuation of the carrier element (on the other hand).

[0009] In this way, a secure fastening of the primary optical element on the carrier element can be achieved, wherein deformations of the primary optical element or its body, in particular deformations due to temperature fluctuations, are avoided or at least reduced. Thus, the smallest possible distance between the light entry surface of the body and the light source can be set and kept constant. In this way, the light efficiency of the individual light sources can be optimally utilized.

[0010] The light sources may be arranged in at least one row, in particular in a plurality of rows (matrix-like). Each light entry surface may be designed to couple a single light distribution of the light source into the body.

[0011] In the sense of the present application, a deformation is in particular a change in the geometry of the primary optical element or the body. A deformation can also mean a mere dimensional change of the primary optical element (when the proportions remain constant).

[0012] According to a further development, the fastening extension can be configured in a U-shape or a V-shape. The fastening extension can mechanically contact the primary optical element from two or three sides. Therefore, the primary optical element can be fastened or fixed on the carrier element on two or three sides thereof.

[0013] As a result, the primary optical element can be accommodated as evenly as possible by means of the carrier element, so that deformations of the primary optical element can be avoided or at least reduced.

[0014] According to a further development, the cross section of the fastening section can be configured to be U-shaped or V-shaped. In particular, the fastening continuation can be received in a U-shaped or V-shaped recess (groove) of the fastening section.

[0015] As a result, the fastening extension can be received in the best possible manner and the primary optical element can be fastened in the best possible manner by means of the fastening section.

[0016] According to one improvement, the primary optical element may have at least one support continuation for spacing the light incident surface of the main body from the light source. The support continuation may be arranged spaced apart from the light incident surface. A plurality of support continuations may be provided.

[0017] As a result, a distance between the light entry surface of the body and the light source that is as constant as possible can be set by simple means. As a result, the light entry surface can be arranged as close as possible to the light source. As a result, the entire individual light distribution of the individual light sources can be used as much as possible or coupled into the primary optical element.

[0018] According to a further development, the carrier element can have at least one opening through which the support continuation can protrude. The carrier element can in particular have a plurality of openings through which a plurality of support continuations protrude.

[0019] The arrangement of the support continuation or the support continuation and the carrier element can thereby be realized with simple means. Furthermore, the arrangement of a support continuation in an opening and / or the arrangement of a plurality of support continuations in a plurality of openings can have a stabilizing effect on the primary optical element.

[0020] According to an improved solution, the lighting device may include a carrier plate. The light source may be arranged on the carrier plate. The support continuation may mechanically contact the carrier plate. The support continuation may be supported on the carrier plate. The support continuation may extend from the primary optical element in the direction of the carrier plate. The carrier plate may be configured as a printed circuit board (e.g., a PCB (printed circuit board) or a PCBA (printed circuit board assembly)).

[0021] As a result, a lighting device that is as compact as possible and has a distance between the light source and the light entrance surface of the primary optical element that is as small and as constant as possible can be realized. Therefore, the entire single light distribution of each light source can be used as much as possible in a lighting device that is as compact as possible or can be coupled into the primary optical element.

[0022] According to one refinement, the primary optical element may include a compensation section for compensating deformations of the primary optical element, in particular deformations caused by temperature. The compensation section may be arranged between the fastening section and the body. The cross section of the compensation section may be configured as a U-shape or a V-shape. It is also conceivable that the cross section of the compensation section may be configured as a straight line.

[0023] The compensating section serves in particular to compensate for (temperature-induced) deformations of the primary optical element and preferably of its body. The compensating section can counteract deformations of the primary optical element, in particular of the body, by its own deformation and at least partially, in particular completely, compensate for these deformations. The compensating section can adjoin the fastening section (on the one hand) and the body (on the other hand). The compensating section can represent a mechanical decoupling between the fixedly clamped or tensioned fastening section and the body of the primary optical element.

[0024] Thus, deformations of the main body and / or the fastening section can be compensated or at least reduced by the compensation section. Thus, deformations of the primary optical element can be avoided or reduced overall.

[0025] According to a further development, the compensating section may be adjacent to the fastening section. The compensating section and the fastening section may be arranged adjacent to each other. The common cross section of the fastening section and the compensating section may be configured in an S-shape, in particular an accordion shape.

[0026] As a result, the compensating section and / or the fastening section can be realized by simple means.

[0027] According to a further development, the primary optical element can have at least one contact section for contacting the carrier element. The contact section can be designed in a stepped manner. The contact section is especially arranged at a distance from the light entrance surface of the main body.

[0028] This allows the primary optical element or its body to be positioned relative to the carrier element. This allows a distance between the light entry surface of the body and the light source that is as constant as possible and thus as small as possible to be achieved.

[0029] According to one refinement, the primary optical element can be made of a flexible material, in particular silicone. The lighting device can include an aperture element for generating a light-dark boundary. The aperture element can mechanically contact the primary optical element, in particular the body. The space or gap arranged between the aperture element and the primary optical element, in particular the body of the primary optical element, can be designed without components, elements and / or fasteners.

[0030] In this way, a lighting device that is as compact as possible and has a light-dark boundary that is as clear as possible can be realized.

[0031] According to a development, the fastening element can be fastened to the carrier element by means of at least one latching connection.

[0032] As a result, a connection between the fastening element and the carrier element can be achieved by simple means.

[0033] Each of the light entry surfaces may be arranged on a continuation of the primary optical element. The carrier element may have a plurality of through-openings. Each continuation may protrude through one through-opening of the carrier element.

[0034] As a result, the primary optical element can be accommodated in the carrier element by simple means and the light entry surface can be placed in a targeted manner in front of the corresponding light source. Furthermore, the continuation arranged in the through-opening can have a stabilizing effect on the primary optical element.

[0035] According to one development, the carrier element can be designed to be transparent (see-through), in particular for the human eye.

[0036] Thereby, absorption of a single light distribution of the light source can be prevented or at least reduced.

[0037] The above-mentioned object is achieved by a lighting device for a vehicle, in particular a motor vehicle, having the features of the present invention.

[0038] The lighting device comprises a plurality of light sources for generating respective single light distributions and at least one primary optical element having a body.

The body comprises a light exit surface for coupling the coupled single light distributions out of the body along a main emission direction. The lighting device comprises at least one carrier element for receiving the primary optical element and at least one fastening element for fastening the primary optical element to the carrier element.

[0039] The primary optical element has at least one support continuation for spacing the light incident surface of the body from the light source. The support continuation may be arranged spaced apart from the light incident surface. A plurality of support continuations may be provided.

[0040] The light sources may be arranged in at least one row, in particular in a plurality of rows (matrix-like). Each light entry surface may be designed to couple a single light distribution of the light source into the body.

[0041] As a result, a distance between the light entry surface of the body and the light source that is as constant as possible can be set by simple means. As a result, the light entry surface can be arranged as close as possible to the light source. As a result, the entire individual light distribution of the individual light sources can be used as much as possible or coupled into the primary optical element.

[0042] According to a further development, the carrier element can have at least one opening through which the support continuation can protrude. The carrier element can in particular have a plurality of openings through which a plurality of support continuations protrude.

[0043] The arrangement of the support continuation or the support continuation and the carrier element can thereby be realized with simple means. Furthermore, the arrangement of a support continuation in an opening and / or the arrangement of a plurality of support continuations in a plurality of openings can have a stabilizing effect on the primary optical element.

The support continuation may mechanically contact the carrier plate. The support continuation may be supported on the carrier plate. The support continuation may extend from the primary optical element in the direction of the carrier plate. The carrier plate may be configured as a printed circuit board (e.g., a PCB (printed circuit board) or a PCBA (printed circuit board assembly)).

[0045] As a result, a lighting device that is as compact as possible and has a distance between the light source and the light entrance surface of the primary optical element that is as small and as constant as possible can be realized.

[0112] As a result, a distance between the light entry surface of the body and the light source that is as constant as possible can be set by simple means. As a result, the light entry surface can be arranged as close as possible to the light source. As a result, the entire individual light distribution of the individual light sources can be used as much as possible or coupled into the primary optical element.

[0113] According to a further development, the carrier element can have at least one opening through which the support continuation can protrude. The carrier element can in particular have a plurality of openings through which a plurality of support continuations protrude.

[0114] The arrangement of the support continuation or of the support continuation and the carrier element can thereby be realized with simple means. Furthermore, the arrangement of a support continuation in one opening or of a plurality of support continuations in a plurality of openings can have a stabilizing effect on the primary optical element.

[0115] According to an improved solution, the lighting device may include a carrier plate. The light source may be arranged on the carrier plate. The support continuation may mechanically contact the carrier plate. The support continuation may be supported on the carrier plate. The support continuation may extend from the primary optical element in the direction of the carrier plate. The carrier plate may be configured as a printed circuit board (e.g., a PCB (printed circuit board) or a PCBA (printed circuit board assembly)).

[0116] As a result, a lighting device that is as compact as possible and has a distance between the light source and the light entrance surface of the primary optical element that is as small and as constant as possible can be realized. Therefore, the entire single light distribution of each light source can be used as much as possible in a lighting device that is as compact as possible or can be coupled into the primary optical element.

[0117] According to one refinement, the primary optical element may include a compensation section for compensating deformations of the primary optical element, in particular deformations caused by temperature. The compensation section may be arranged between the fastening section and the body. The cross section of the compensation section may be configured as a U-shape or a V-shape. It is also conceivable that the cross section of the compensation section may be configured as a straight line.

[0118] The compensating section serves in particular to compensate for (temperature-induced) deformations of the primary optical element and preferably of its body. The compensating section can counteract deformations of the primary optical element, in particular of the body, by its own deformation and at least partially, in particular completely, compensate for these deformations. The compensating section can adjoin the fastening section (on the one hand) and the body (on the other hand). The compensating section can represent a mechanical decoupling between the fixedly clamped or tensioned fastening section and the body of the primary optical element.

[0119] Thus, deformations of the main body and / or the fastening section can be compensated or at least reduced by the compensation section. Thus, deformations of the primary optical element can be avoided or reduced overall.

[0120] According to a further development, the compensating section may be adjacent to the fastening section. The compensating section and the fastening section may be arranged adjacent to each other. The common cross section of the fastening section and the compensating section may be configured in an S-shape, in particular an accordion shape.

[0121] As a result, the compensating section and / or the fastening section can be realized by simple means.

[0122] According to a further development, the primary optical element can have at least one contact section for contacting the carrier element. The contact section can be designed in a stepped manner. The contact section is especially arranged at a distance from the light entrance surface of the main body.

[0123] This allows the primary optical element or its body to be positioned relative to the carrier element. This allows a distance between the light entry surface of the body and the light source that is as constant as possible and thus as small as possible to be achieved.

[0124] According to a development, the fastening element can be fastened to the carrier element by means of at least one latching connection.

[0125] As a result, a connection between the fastening element and the carrier element can be achieved by simple means.

[0126] Each of the light entry surfaces may be arranged on a continuation of the primary optical element. The carrier element may have a plurality of through-openings. Each continuation may protrude through one through-opening of the carrier element.

[0127] As a result, the primary optical element can be accommodated in the carrier element by simple means and the light entry surface can be placed in a targeted manner in front of the corresponding light source. Furthermore, the continuation arranged in the through-opening can have a stabilizing effect on the primary optical element.

[0128] According to one development, the carrier element can be designed to be transparent (see-through), in particular for the human eye.

[0129] Thereby, absorption of a single light distribution of the light source can be prevented or at least reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0143] In the following description and in the accompanying drawings, corresponding components and elements are marked with the same reference numerals. For the sake of clarity, not all reference numerals are reproduced in all drawings.

[0144] Figure 1 shows a perspective exploded view of the lighting device according to the first embodiment, and Figure 2 A perspective view of a lighting device 10 according to a first embodiment is shown. The lighting device 10 may be a lighting device 10 for a vehicle, in particular a motor vehicle.

[0145] In the present case, the lighting device 10 comprises a primary optical element 16, a carrier element 22 for receiving the primary optical element 16, and a fastening element 24 for fastening the primary optical element 16 to the carrier element 22. In the present case, the lighting device 10 is configured to emit a light distribution along a main emission direction 15. The main emission direction is indicated in the figure by means of an arrow.

[0146] The fastening element 24 can be fastened to the carrier element 22 by means of a latching connection 41. For this purpose, in the present case, the carrier element 22 has a latching nose 43 on its two opposite sides, and the fastening element 24 has a latching opening 45 on its two opposite sides. The latching nose 43 and the latching opening 45 are designed so that the latching nose 43 snaps into the latching opening 45 or engages back into the latching opening 45 and thus forms a latching connection 41 for fixing or fastening the fastening element 24 to the carrier element 22.

[0147] The carrier element 22 can be designed to be transparent, in particular for the human eye. In other words, the carrier element 22 can be designed to be see-through.

[0148] The lighting device 10 may include an aperture element 40 for generating a light-dark boundary (HDG) on the road.

[0149] The lighting device 10 may include a lighting unit having a light source (LED) and a primary optical device (not shown). The lighting unit may be configured to generate a low beam of the vehicle. Figure 5 and / or Fig.11 The lighting unit may be arranged above the aperture element 40. The lighting unit may be configured to generate a light distribution below the HDG (low beam).

[0150] The light distribution generated by the primary optical element 16 can represent a high beam and / or be configured to generate a high beam of the vehicle. The primary optical element 16 can be configured to generate a light distribution above and below the HDG (high beam). In other words, the primary optical element 16 distributes the high beam, in particular, above and below the HDG.

[0151] Figure 3 Shown according to Figure 1A perspective view of the primary optical element 16 of the lighting device 10, and Figure 4 Shown according to Figure 1 A perspective view of an illumination device 10 having an aperture element 40 is shown.

[0152] The aperture element 40 is designed as a plate with a sharp edge aligned in the main emission direction 15 .

[0153] Figure 5 Shown according to Figure 1 A cross-sectional view of the lighting device 10, and Figure 6 Shown according to Figure 1 1 is a longitudinal sectional view of the lighting device 10. In the present case, the cross section and the longitudinal section are two cross sections of the lighting device 10 which are arranged orthogonally to each other.

[0154] The lighting device comprises a plurality of light sources 14 for generating corresponding single light distributions. The light sources 14 can be configured as LEDs (light emitting diodes). The light sources 14 can be switched on and / or off collectively, individually or in groups. The primary optical element 16 has a body 13 .

[0155] The body 13 has a plurality of light incident surfaces 18 for coupling a single light distribution generated by the light source 14 into the body 13 (see Figure 3 The body 13 has at least one light exit surface 20 for coupling the coupled-in single light distribution out of the body 13 along the main emission direction 15. The body 13 is used in particular to further guide the coupled-in light and to couple the light out along the main emission direction 15.

[0156] In the present case, the carrier element 22 has a fastening continuation 26 . The primary optical element 16 has a fastening section 28 . The fastening section 28 is designed to receive the fastening continuation 26 . The fastening section 28 of the primary optical element 16 is arranged, in particular clamped, between the fastening element 24 and the fastening continuation 26 of the carrier element 22 .

[0157] The fastening element 24 can be flexibly designed and, in particular due to the fastening to the carrier element 22 (by means of the latching connection 41 ), exert a force on the fastening section 28 which is directed in the direction of the fastening extension 26 and thus tensions the fastening section 28 .

[0158] In the present case, the fastening extension 26 and the fastening section 28 are each designed to be U-shaped (see Figure 1 and Figure 3 ). The fastening continuation 26 and the fastening section 28 therefore each extend on three adjacent sides of the primary optical element 16 .

[0159] In the present case, the cross section of the fastening section 28 is designed to be U-shaped. In other words, in the present case, the fastening section 28 is designed in the form of a U-shaped groove. Therefore, the fastening continuation 26 can be accommodated in the fastening section 28. In particular, the fastening section 28 can surround or surround the fastening continuation 26 at least in the area facing the fastening section 28.

[0160] It is also conceivable that the fastening extension 26 , the fastening section 28 and / or the cross section of the fastening section 28 can be of V-shaped design.

[0161] In the present case, the primary optical element 16 has, by way of example, a compensation section 36 for compensating deformations of the primary optical element 16, in particular deformations caused by temperature. In the present case, the compensation section 36 is arranged between the fastening section 28 and the body 13. In the present case, the cross section of the compensation section 36 is designed as a straight line. It is also conceivable that the cross section of the compensation section 36 can be designed as a U-shape or a V-shape. Mechanical vibrations and / or deformations can be compensated by the compensation section 36. The compensation section 36 in particular forms a mechanical decoupling between the body 13 and the fastening section 28.

[0162] In the present case, the compensation section 36 exemplarily adjoins the fastening section 28 . The compensation section 36 is arranged between the body 13 and the fastening section 28 , which is determined relative to the rest of the lighting device 10 , in order to compensate for deformations of the primary optical element 16 .

[0163] In the present case, the lighting device comprises a carrier plate 34. The light source 14 is arranged on the carrier plate 34. In the present case, the carrier plate 34 is formed in the form of a printed circuit board (for example a PCB or PCBA). In the present case, the carrier element 22 contacts the carrier plate 34. The carrier element 22 is supported on the carrier plate 34.

[0164] In the present case, each of the light entrance surfaces 18 is arranged on a continuation 42 of the primary optical element 16 (or the body 13). The carrier element 22 has a plurality of through openings 44. In the present case, each continuation 42 protrudes through a through opening 44 of the carrier element 22. Thus, the light entrance surface 18 can be placed in a targeted manner in front of the corresponding light source 14.

[0165] In the present case, the light entrance surface 18 or the continuation 42 and the light sources 14 are each arranged in a row.

[0166] In the present case, the primary optical element 16 has a contact section 38 for contacting the carrier element 22. In the present case, the contact section 38 is formed in the form of a step on each of the continuations 42 of the primary optical element 16 or its body 13 (see Figure 3). The primary optical element 16 can rest together with the contact section 38 on the carrier element 22 or be tensioned against the carrier element 22. This tensioning can be achieved, for example, by pressing the fastening element 24 against the fastening section 28. In other words, a force can be exerted on the fastening section 28 in the direction of the carrier element 22 by means of the fastening element 24, wherein the force presses the primary optical element 16 and in particular its body 13 (with the corresponding continuation 42) with the contact section 38 against the carrier element 22 or onto the carrier element 22. This force can be generated, for example, by fastening the (flexible) fastening element 24 to the carrier element 22 (by means of the latching connection 41).

[0167] The primary optical element 16 can be made of a flexible material, in particular silicone. The aperture element 40 can mechanically contact the primary optical element 16 and in particular its body 13. The aperture element 40 can be arranged in the immediate vicinity of the primary optical element 16 or its body 13. In particular, no fasteners and / or other elements or components are provided between the aperture element 40 and the primary optical element 16 or its body 13.

[0168] Figure 7 shows a perspective exploded view of the lighting device 10 according to the second embodiment, and Figure 8 A perspective view of the lighting device 10 according to the second embodiment is shown. The second embodiment of the lighting device 10 may have one, more or all of the above features of the lighting device 10 according to the first embodiment.

[0169] Fig. 9 Shown according to Figure 7 A perspective view of the primary optical element 16 of the lighting device 10, and Fig.10 Shown according to Figure 7 A perspective view of an illumination device 10 having an aperture element 40 is shown.

[0170] Fig.11 Shown according to Figure 7 A cross-sectional view of the lighting device 10, and Fig.12 Shown according to Figure 7 1 is a longitudinal sectional view of the lighting device 10. In the present case, the cross section and the longitudinal section are two cross sections of the lighting device 10 which are arranged orthogonally to each other.

[0171] The lighting device 10 according to the second embodiment is different from the first embodiment in the following aspects:

[0172] In the present case, the light entrance surface 18 or the continuation 42 and the light sources 14 are each arranged in two rows (matrix-like). The light sources 14 can be switched on and / or off jointly, individually or in groups.

[0173] In the present case, the primary optical element 16 has four support continuations 30 for spacing the light entrance surface 18 of the body 13 from the light source 14 (see Fig. 9 The support continuation 30 is arranged spaced apart from the light incident surface 18 .

[0174] In the present case, the carrier element 22 has four openings 32, wherein the support continuations 30 (in the direction of the carrier plate 34) protrude through these openings 32. The support continuations 30 each contact the carrier plate 34 and are supported on the carrier plate 34. With the aid of the support continuations 30, a constant distance between the primary optical element 16 or its body 13 and thus the light entrance surface 18 and the light source 14 arranged on the carrier plate 34 can be achieved. Thus, the desired distance between the light entrance surface 18 and the light source 14 can be set by selecting the length of the support continuation 30.

[0175] Thus, at least one of the support continuations 30 is supported on the carrier plate 34. The support continuation 30 is connected, in particular connected in one piece, to the body 13 of the primary optical element 16 on the side of the support continuation 30 facing away from the carrier plate 34, in which the light generated by the light source 18 is focused. The individual continuations 42 project from the body 13 of the primary optical element 16 in the direction of the respectively assigned light source 14.

[0176] The temperature-induced length change of the at least one support continuation 30, the body 13 and the continuation 42 ensures that the distance between the light entry surfaces 18 of the light sources 14 changes as little as possible in relation to the light coupling-in. In other words, the primary optical element 16 has at least one support continuation 30 for spacing the light entry surface 18 of the body 13 from the light source 14, in particular its light exit surface.

[0177] Since the primary optical element 16 rests on or is tensioned against the carrier plate 34 with the support continuation 30, the contact section 38 according to the first embodiment is not required. However, it is conceivable that the lighting device 10 according to the second embodiment can have a contact section 38 according to the first embodiment. The tensioning of the primary optical element 16 can be achieved similarly to the first embodiment (as described above) by pressing the fastening element 24 against the fastening section 28. The force acting on the fastening section 28 and thus on the primary optical element 16 in this way presses the primary optical element 16 with its support continuation 30 onto the carrier plate 34.

[0178] In the present case, the cross section of the compensation section 36 of the primary optical element 16 is designed to be V-shaped. It is also conceivable that the cross section of the compensation section 36 can be designed to be U-shaped or straight. Mechanical vibrations and / or deformations can be compensated by the compensation section 36. The compensation section 36 in particular forms a mechanical decoupling between the body 13 and the fastening section 28.

[0179] In the present case, the compensating section 36 adjoins the fastening section 28 by way of example. In the present case, the common cross section of the fastening section 28 and the compensating section 36 is designed as an S. In other words, the common cross section of the fastening section 28 and the compensating section 36 is designed as an accordion.

[0180] The compensation section 36 is arranged between the body 13 and the fastening section 28 which is determined relative to the rest of the lighting device 10 in order to compensate for deformations of the primary optical element 16 .
