Description

[0001] The invention is based on an optical arrangement for a vehicle and a vehicle.

[0002] In the automotive sector, lighting design, such as the design of lighting functions, for example signal light functions, is becoming increasingly important, and elements on the vehicle that were previously unlit are increasingly being illuminated, i.e., provided with active lighting elements.

[0003] US Patent 2018 / 0 272 927 A1 discloses the use of a circumferential light guide to illuminate the radiator grille. Another solution for illuminating the radiator grille is known from US Patent 2005 / 0 236 870 A1, in which the individual radiator fins are illuminated. An illuminated gearshift indicator is known from German Patent DE 10 2009 011 948 A1, in which a screen with translucent symbols is illuminated by means of a light guide on the back of the indicator. Furthermore, illuminated buttons are disclosed in WO 2013 / 168651 A1, the function symbols of which are illuminated by means of a light source, the light emitted by the light source being guided to the individual buttons by branched light guides.

[0004] To achieve a lighting design similar to that of existing luminaires, such as existing signal lights, in the automotive sector, reflectors, diffusers, diffusers, OLEDs (organic light-emitting diodes), light guides or other refractive optical elements are primarily used.

[0005] With electric vehicles, it is now possible, for example, to use certain areas of the vehicle that were previously unlit, such as a section of the radiator grille (i.e., the area between the headlights), for extensive or at least largely illuminating purposes, since the cooling function provided by airflow through the grille is no longer necessary. Displays or other full-surface lighting arrangements can be used for this purpose. However, this is not possible, or only possible to a lesser extent, with vehicles powered by combustion engines, as the cooling effect of airflow through the radiator grille must still be ensured.

[0006] One object of the invention is to create a technically simple and cost-effective optical arrangement for illuminating a vehicle component that has a high aesthetic appeal. A further object of the invention is to create a vehicle that has a vehicle component illuminated with a high aesthetic appeal.

[0007] The problem with regard to the optical arrangement is solved according to the features of claim 1 or according to the features of claim 3. Furthermore, the problem with regard to the vehicle is solved according to the features of claim 11.

[0008] Particularly advantageous features can be found in the dependent claims.

[0009] According to the invention, an arrangement for a vehicle is provided according to a (first) independent embodiment, wherein the arrangement comprises a vehicle component, such as a fender or a radiator grille. The vehicle component has at least one visible surface. This surface can be perceived from the interior of the vehicle and / or by an observer when viewing the vehicle from the outside. The visible surface of the vehicle component has a plurality or a multiplicity of light-emitting areas, which in particular form a light pattern. A respective output surface of at least some of the output surfaces, or a respective output surface of all output surfaces, is each assigned to a light-emitting area, such that light can be emitted from the light-emitting area to which an output surface is assigned in order to emit at least one sign.

[0010] The arrangement described above makes it possible to illuminate a vehicle component with a visible surface, particularly one of any shape, such as a grid structure, and / or to emit light from the component. For example, bumpers, fenders, trim panels, A-, B-, C-, or D-pillars, doors, trunk lids, or hoods (etc.) can be equipped with light-emitting areas to illuminate the component with a high degree of aesthetic appeal. The light guide, which has multiple output surfaces assigned to a specific light-emitting area, can be flexibly designed. This allows even vehicle components that are not fully formed, such as a radiator grille or a ventilation grille, but have cutouts, for example, for air ducts, to be illuminated.Another advantage is that the coupling surfaces of the light guide, each assigned to a light-emitting area, can be flexibly positioned on the vehicle component depending on the application, allowing for free design.

[0011] In a further independent (second) embodiment, an arrangement comprises a vehicle component, such as a fender, a radiator grille, or a bumper (etc.). The vehicle component has at least one visible surface. The visible surface of the vehicle component has a plurality or a multitude of light-emitting areas, which in particular form a light pattern. The arrangement comprises a plurality or a multitude of light sources, such as LEDs (light-emitting diodes). A respective output surface of each light source, at least some of the light sources, or all of the light sources, is assigned to one of the light-emitting areas. Thus, light can be emitted from the light-emitting area. Furthermore, the arrangement comprises an image mask for one, at least some, or all of the light-emitting areas.Alternatively, a plurality or multiplicity of image masks can be provided, wherein a respective image mask can be provided for a respective light-emitting area, at least a part of the light-emitting areas, or all light-emitting areas.

[0012] One advantage of the arrangement described above for a vehicle with multiple light sources is that the light sources, whose output surfaces are assigned to a respective light-emitting area, can be flexibly positioned on the vehicle component. The light sources can be wired together (e.g., in specific chains) or separately (individually), so that there are no restrictions on their positioning with regard to power supply. The light-emitting areas can be positioned anywhere on the visible surface of the vehicle component, regardless of the component's shape. In other words, the arrangement according to the second embodiment offers maximum flexibility with regard to the design and number of light sources. Furthermore, illumination of, for example, comb-like or grid-like vehicle components, such as a radiator grille, can be easily achieved.Another advantage is that, due to the multitude of light sources, a very low light output is sufficient for each light source to illuminate the vehicle component. Therefore, simple and inexpensive light sources can be used, and, for example, the low power consumption of these low-power light sources eliminates the need for cooling. This saves costs, weight, and installation space. Thus, compact, lightweight, and cost-effective illumination of a vehicle component is achievable. The image mask allows for the emission of a light image, particularly one containing information, which can be easily and cost-effectively customized. For example, the image mask can be used to emit a light image in the form of a symbol, such as a logo, especially a brand logo.

[0013] The arrangement according to the second embodiment can include at least one optical element. This optical element can be located downstream of a light source in the optical arrangement. It is also possible for a separate optical element to be provided for at least some or all of the light sources. The optical element is preferably a light guide. In particular, the optical element can be located between at least one of the light sources and the image mask. The light coupled out from a single output surface of the plurality of light sources can be additionally directed by the light guide. This is also advantageous because the light guide can have a suitable shape so that the image mask can be easily attached to it.

[0014] According to the invention, the arrangement according to the first embodiment has an image mask for at least a portion of the light-emitting areas or for all light-emitting areas. Additionally or alternatively, a plurality or multiplicity of image masks can also be provided, wherein a respective image mask can be provided for a respective light-emitting area of ​​at least a portion of the light-emitting areas or for all light-emitting areas. The at least one image mask can preferably be arranged on at least one of the output surfaces of the optical fiber.

[0015] The at least one image mask, described below, can be arranged on at least one of the output surfaces of the optical fiber of the arrangement according to the first embodiment, or on the output surface of at least one of the light sources of the arrangement according to the second embodiment, and / or on the output surface of a respective optical element of at least one of the light sources of the arrangement according to the second embodiment. Furthermore, the optical fiber of the arrangement according to the first embodiment, or one of the light sources of the arrangement according to the second embodiment, and / or the optical element of the arrangement according to the second embodiment are referred to below as components.

[0016] The at least one image mask of the arrangement according to the first or second embodiment can, for example, be cap-shaped. That is, the image mask can be designed in the shape of a socket or a can. In other words, the at least one image mask is hollow and cylindrical and has a base that closes one side of the hollow cylinder. This is advantageous because each cap-shaped image mask can simply be placed or attached to a respective output surface and / or to the component. In particular, a recess, especially a continuous one, can be provided in the base of the image mask through which light emitted from the output surface can shine. The recess can, for example, be shaped like a symbol or logo. Thus, the light-emitting area to which the at least one image mask is assigned can emit this logo as a light image. However, the recess can also be purely optically functional, i.e.,Optically transparent (e.g., through two-component injection molding) although mechanically sealed. It is also possible that the image mask does not have a continuous opening, but rather at least one area with a comparatively thinner material through which light can pass. It is also possible that the image mask has at least two areas of different material thicknesses through which light can pass with varying intensity, so that these areas appear differently bright to the viewer. In this way, a symbol, such as a logo, can be formed by varying the material thickness of the image mask. It is also possible to perforate the image mask and thus emit a symbol, especially a brand logo, as a light image through its arrangement.

[0017] If a specific image mask is provided for a specific output surface of the component, these masks can be configured differently. It is also possible that at least some of the image masks are identical.

[0018] If a common image mask is provided for at least some of the light-emitting areas, it can, for example, have a plurality or multiple of cap-shaped, socket-shaped, or can-shaped individual image masks, and these can be connected, for example, via one or more bridges (e.g., even up to a grid). This makes the image masks easy to handle.

[0019] The at least one image mask can be designed, for example, as a slide and / or as a gobo (graphic optical blackout). If the image mask, or at least one of the respective image masks, is designed as a slide, it is possible for the light-emitting areas to emit light with different colors, shades of gray, and / or intensities. The at least one image mask allows the arrangement according to the first or second embodiment to emit a photographic image that displays at least one symbol, such as a brand logo. Thus, the photographic image of the arrangement according to the first or second embodiment can be individualized, particularly retrospectively, by applying the image mask and / or the respective image masks.For example, a customer, such as an OEM (Original Equipment Manufacturer) or vehicle manufacturer, or an end customer purchasing the vehicle, may be able to configure the shape and color of the photographic arrangement according to their own design preferences. In the tuning sector, it is also possible to easily customize the appearance of a vehicle by replacing the image masks.

[0020] According to the invention, the image mask, or a specific image mask, is arranged on at least one of the output surfaces. A portion of the output surface not covered by the image mask projects out through the recess and / or into the recess of the image mask. This has the advantage that the portion projecting beyond the image mask is visible even when viewing the light-emitting area from the side, thus creating a 3D effect. It is particularly advantageous if the portion of the output surface projecting from the image mask has the same shape and size as the recess of the image mask. This design is advantageous because the light image of the arrangement is visible not only when viewing the visible surface from a near-frontal angle, but also from the side. Furthermore, this opens up a wide range of design possibilities.It is also possible that the entire area not covered by the image mask protrudes beyond the image mask and / or at least partially projects into the recess. In other words, the area of ​​the output surface not covered by the image mask at least partially penetrates the image mask.

[0021] In another embodiment, the image mask, or the respective image mask, can be positively connected to at least one of the coupling surfaces or to the component, so that they can be connected, for example, like two puzzle pieces. In other words, as described above, the coupling surface can project at least partially beyond the at least one image mask or project into the recess of the image mask, and the recess of the image mask can be designed such that it has a negative form of the part of the coupling surface that projects beyond the image mask. This is advantageous because the at least one image mask can then be positively attached simply by placing or snapping the image mask onto the coupling surface, and no further fastening means are necessary. Furthermore, it is possible for the at least one image mask to be designed such that it forms an interference fit or transition fit with the component.In other words, the image mask can, for example, have a slightly smaller inner diameter than the component.

[0022] The image mask can also be mechanically attached to the component. For example, it can be fixed in place using a clip mechanism. Alternatively, the image mask can also be glued to the component. Attachment via a clip mechanism is advantageous because the image mask can then be easily replaced, for example, in case of a defect.

[0023] Furthermore, the arrangement according to the first embodiment, and according to the second embodiment, may have at least one further element and / or at least one further respective element for at least a portion of the light-emitting areas. The element or elements may, for example, be an optical element into which light coupled out from at least one output surface of the component is further shaped. This is advantageous because the light coupled out from at least one output surface can then be shaped again. For example, the element or elements may be an aperture or a scattering geometry that scatters light coupled into it.Furthermore, the element or elements in question make it possible to broaden the viewing angle of the light exiting the at least one output coupling surface and coupling into the element or elements in question, so that the light emitted by the arrangement is visible from a wider viewing angle. Additionally or alternatively, the element or elements in question can, for example, be a lens and / or a refractive optical element to influence the light exiting at least one of the output coupling surfaces, thus enabling a variety of lighting design options. In the arrangement according to the first or second embodiment, the element can be positioned upstream or downstream of the image mask.

[0024] In a further embodiment, the optical element and / or the image mask itself can be, for example, at least partially semi-transparent and / or tinted. This means that the element and / or the image mask can be, for example, a diffuser and / or a lacquer and / or a perforated / textured lacquer, such that at least part of the light-emitting areas are optically positioned in front of the element, either entirely or partially, so that they are not visible to an observer when the element is not switched on—that is, they are "hidden" and not immediately apparent. This means that the light sources of the arrangement according to the second embodiment or the light guide of the arrangement according to the first embodiment are concealed and not visible, and the light-emitting areas only become visible when the arrangement is switched on. This allows for a further lighting design option.

[0025] To create further lighting effects, it is also possible to frost at least one of the output surfaces. This allows at least that output surface to emit diffuse light. For example, some of the output surfaces can emit light diffusely, while others do not. This allows for the creation of various lighting design effects.

[0026] Furthermore, each output surface can have any geometric shape. For example, the output surface can be circular, rectangular, or free-form. This is another way to customize the lighting through its arrangement.

[0027] Preferably, the vehicle component has a comb-like or grid structure or grid pattern, or is designed as a grid or grid structure. For example, the vehicle component can be a radiator grille or a ventilation grille. The grid pattern or grid shape of the vehicle component can be, for example, a rectangular grid and / or a honeycomb grid and / or a triangular grid and / or a combination thereof. In particular, the light-emitting areas can be arranged at the intersections of grid struts, in other words, at grid points, and / or on the grid struts themselves. The outer basic shape of the vehicle component is preferably also free-form.

[0028] Depending on the design requirements, the light-emitting areas can be freely arranged, but are particularly suitable for use at the intersections of grid struts and / or grid bars of the grid-shaped vehicle component and / or the vehicle component with a grid pattern. These light-emitting areas can be located, for example, on a portion of the visible surface or distributed across the entire visible surface of the vehicle component. The arrangement of the light-emitting areas can be symmetrical, periodic, asymmetrical, or aperiodic. Therefore, there are a wide variety of ways to illuminate the vehicle component through its arrangement.

[0029] The light source of the arrangement according to the first embodiment and / or at least some of the light sources of the arrangement according to the second embodiment is / are preferably integrated into the vehicle component. For example, the vehicle component can be manufactured by injection molding, and the light source of the arrangement according to the first embodiment or the light sources of the arrangement according to the second embodiment can be overmolded with a material, in particular a plastic, during the manufacturing process of the vehicle component. In particular, power supply lines, for example cables configured for power supply and / or control of the light source(s), can also be integrated into the vehicle component, in particular overmolded. This is advantageous because it makes attaching the light source(s) simple and cost-effective.A further advantage is that the light source(s) and / or the cable are thus easily protected from external influences such as moisture and / or dirt. The light guide of the arrangement according to the first embodiment can also be at least partially integrated into the vehicle component. For example, the vehicle component with the light guide according to the arrangement of the first embodiment can be manufactured using a two-component injection molding process, thus saving costs and time in the production of the arrangement.

[0030] Preferably, at least one control unit can be provided that controls the light source for the light guide of the arrangement according to the first embodiment and / or at least some of the light sources of the arrangement according to the second embodiment. Depending on its capabilities, the control unit can range from "power supply only" to "power supply plus LIN or CAN". In particular, the control unit can be connected to an app and / or other input device, allowing an end user and / or a vehicle manufacturer to control the arrangement. For example, it is possible to dim the light source(s), change the light intensity and / or color, and / or switch the arrangement on and off. Various, including dynamic, personalized sequences can be stored in non-volatile memory and, if necessary, assigned to different actions, such as ignition on, flashing, etc.

[0031] Light can be emitted from at least one of the coupling surfaces of the at least one component of the arrangement according to the first or second embodiment, partially and / or at least temporarily, with a different brightness and / or color than from another coupling surface. If the component is, for example, the optical fiber according to the first embodiment, it is possible that the arrangement has at least two light sources that emit light of different colors. By coupling the light from the light sources via, for example, two different coupling surfaces, light of a different color can be emitted from at least one coupling surface that is located closer to the first coupling surface than from the at least one coupling surface of the optical fiber that is located closer to the other coupling surface.The arrangement of the second embodiment can, for example, include at least two different light sources that emit light of different colors and / or light of different brightness. This allows for further design possibilities. If the arrangement according to the first or second embodiment includes multiple light sources, these can, for example, be RGB LEDs (red-green-blue LEDs). This makes it possible, for example, to create further patterns. It is possible for several LEDs to be arranged in one housing. It is also possible for each LED to be arranged in its own housing.

[0032] The optical fiber of the arrangement according to the first embodiment preferably comprises a base optical fiber, which has at least one coupling surface, and a plurality of branch optical fibers. These each have at least one coupling surface. The branch optical fibers preferably branch off from the base optical fiber. For example, the optical fiber as a whole can be comb-shaped, with the prongs being the branch optical fibers. That is, the branch optical fibers can each project from the base optical fiber at right angles in the same direction, i.e., parallel, at regular intervals from one another. It is also possible for the branch optical fibers to project from the base optical fiber at right angles but in different directions. For example, the branch optical fibers can have an angle of 5°, 10°, or even 20° to each other.In another embodiment, it is also possible for the branch optical fibers to extend from the base optical fiber in a branch-like manner. This means that the branch optical fibers can each extend from the base optical fiber in any direction, and the direction of extension can, for example, be at an angle other than 90° to the direction of extension of the base optical fiber. The branch optical fibers can also branch off from each other. This means that at least one branch optical fiber can branch off from the base optical fiber, and at least one further branch optical fiber can branch off from this branch optical fiber.

[0033] In a further embodiment, the optical fiber of the arrangement according to the first embodiment can have a plurality of base optical fibers, each of which has a plurality of branch optical fibers. The base optical fibers can, for example, be connected to form a grid-like base optical fiber, or the base optical fibers can be arranged at a distance from each other, for example, in a row with a parallel spacing. Furthermore, the arrangement can have a light source whose light couples into the plurality of base optical fibers through the coupling surface of a single base optical fiber, and / or the arrangement can have a plurality of light sources, wherein, for example, each light source can be assigned to a specific base optical fiber. However, it is also possible that one optical fiber is assigned to a plurality of light sources and / or that one light source is assigned to a plurality of optical fibers.

[0034] It is also advantageous if the optical fiber of the arrangement of the first embodiment has at least one or a respective coupling structure for each branch optical fiber of at least a portion of the branch optical fibers. The coupling structure is preferably designed such that at least a portion of the light in the base optical fiber can be coupled into at least one branch optical fiber. In particular, each branch optical fiber is associated with a coupling structure. The coupling structure(s) can be designed such that the brightness of the light coupled out from each coupling surface is uniform. It is also possible for the brightness of the light coupled out from the coupling surfaces to be different.For example, the brightness of the light can gradually decrease from one light-emitting area to an adjacent one if the light-emitting areas are arranged in a row. A variety of different effects can be created by configuring the output coupling structure. Furthermore, the specific output coupling structure allows light to be directed precisely to the output surfaces.

[0035] The output coupling structure can, for example, be prism-like. If the output coupling structure is prism-like, the base optical fiber can have a corresponding prism-like output coupling structure at each branch optical fiber. In particular, the prism-like output coupling structure is a reflecting prism that is incorporated as a recess in the base optical fiber or applied as an additional volume to the base optical fiber. The at least one prism-like output coupling structure is preferably formed on a longitudinal side of the base optical fiber that faces away from the side from which the associated branch optical fiber projects. If the output coupling structure is designed as a recess, it can penetrate at least a portion of the cross-section of the base optical fiber.In particular, light propagating in the main optical fiber is at least partially coupled from the output structure, which is designed as an optical prism, into the corresponding optical fiber. An advantage of the prism-like output structure is that the direction and amount of light coupled out by the prism and coupled into the respective branch optical fiber can be adjusted by the prism's shape and / or size. It is also possible for the output structures of the branch optical fibers to differ from one another. For example, they can have different configurations to achieve homogeneous illumination.

[0036] The output structure can also be introduced into the base optical fiber using a laser. In other words, a surface can be created using a laser. This surface can, for example, be an internal engraving formed from gas bubbles. In other words, the surface introduced by the laser is a surface formed within the base optical fiber, which can be created from gas bubbles, particularly air bubbles, introduced into the material of the base optical fiber by the laser. Due to the material transition and the difference in refractive index between the base optical fiber and the gas present in the gas bubbles, the air bubbles scatter the light, for example diffusely, and couple the light into the branch optical fiber. The surface introduced into the base optical fiber can be created in a completely freeform or 3D geometry.Depending on the position, number, and density of the air bubbles in the surface, the proportion of light coupled into the branching optical fiber can be adjusted. This means there are various ways to implement the coupling structure, and the implementation method may depend, for example, on the intended application of the arrangement. One advantage of laser-applied coupling structures is that they can be designed very precisely, and no costly tool changes are necessary for adjustments. The laser can be used to create various coupling structures.

[0037] Other coupling structures (especially when processed by a laser) can include, for example (but are not limited to): spherical segments, freeform shapes, and irregular roughening. The spherical segments can, for instance, be periodically embedded in the base optical fiber. Furthermore, coupling structures, such as the spherical segments, can be introduced into the base optical fiber using a die or directly generated during the manufacturing process of the optical fiber, for example, by injection molding.

[0038] Furthermore, it is possible, particularly with a laser, to roughen a prism surface of the prism-like output coupling structure. This allows the light reflected from the roughened prism surface to reflect diffusely and couple into the branching optical fiber.

[0039] The optical fiber according to the first embodiment can be assigned at least one light source. However, it is also possible for the light from at least two light sources to be coupled into the optical fiber via individual and / or a common coupling surface. If the light sources have a common coupling surface, it is advantageous if this surface is large enough that preferably a large proportion of the light from the light sources can be coupled into the coupling surface. If at least two light sources are provided whose light couples into a common coupling surface, they can be arranged in a common housing. It is also possible for the light sources to each have their own housing. The light sources can, for example, be controlled differently, so that different patterns can be created depending on whether the light source is switched on or off.

[0040] It is also possible, for example, to arrange a light source directly at at least one branch optical fiber to generate further light patterns. For instance, light from a light source can be coupled directly into an output coupling structure. Preferably, the light from the light source can be coupled into the base optical fiber on a side facing away from the side from which the branch optical fiber projects.

[0041] The number of branch optical fibers can be arbitrary. Furthermore, the shape of the main optical fiber and / or the shape of the individual branch optical fibers can be freely selected. In this way, at least one branch optical fiber can have a cross-section that differs from another branch optical fiber. Additionally, a cross-section that changes in a longitudinal direction of the branch optical fiber or the main optical fiber is possible. For example, the main optical fiber and / or the branch optical fibers can have a circular cross-section, particularly with a flattened side, and / or an elliptical cross-section, or a rectangular cross-section, and / or a square cross-section, and / or a keyhole-shaped cross-section.The "keyhole-shaped" cross-section preferably has two sections, a first section being rectangular, square, or trapezoidal, and a second section being round. However, other polygons or freeform shapes are also conceivable as cross-sections.

[0042] Furthermore, the arrangement of the first embodiment can include a collimator for coupling the light from the light source(s) into the optical fiber, and / or the optical fiber can have various and / or one optically active surface(s) through which the light from the light source(s) can be effectively coupled into the optical fiber. The design of the coupling surface can depend on the application of the arrangement.

[0043] The light sources of the arrangement according to the second embodiment can, for example, be wired via a network-like structure and / or be individually wired, meaning that each light source has its own power supply extending from a power source to the respective light source, and / or be wired in series. The wiring of the light sources can be adapted to the shape of the vehicle component, so that the wiring is, for example, not visible and can be easily integrated into the vehicle component.

[0044] Preferably, the arrangement according to the first or second embodiment fulfills a signal light function of a vehicle on which it may be mounted. Preferably, the signal light function(s) provided are a turn signal function, a brake light function, a taillight function, a daytime running light function, a position light function, a rear fog light function, a combination of the aforementioned, and / or other functions. This is advantageous because, in addition to a design effect, a function, such as the position light function, can thus be fulfilled.

[0045] In particular, the vehicle component can be made, at least partially, from a plastic, especially a thermally conductive one, such as ABS (acrylonitrile butadiene styrene copolymer), in one embodiment of the arrangement according to the first or second embodiment. If the vehicle component is made of plastic, it is particularly advantageous if it is manufactured by injection molding, since the light source(s) and / or the wiring can then be easily integrated into the vehicle component during the molding process. However, it is also possible for the vehicle component to be made, at least partially, of glass, PC (polycarbonate), PMMA (polymethyl methacrylate), GRP (glass fiber reinforced plastic), metal (e.g., chromium), wood, or carbon fiber.

[0046] The vehicle component is preferably a body panel or part of an interior trim panel of a vehicle. Preferably, the vehicle component is a radiator grille, in particular a radiator grille of a vehicle with an internal combustion engine.

[0047] The light sources of the arrangement according to the second embodiment, or the at least one light source of the arrangement according to the first embodiment, can each be configured as a light-emitting diode (LED), and / or as an organic LED (OLED), and / or as a laser diode, and / or as a light source operating on the Laser Activated Remote Phosphor (LARP) principle, and / or as a halogen lamp, and / or as a high-intensity discharge (HID) lamp, and / or in conjunction with a projector operating on the Digital Light Processing (DLP) principle. Each light source of the arrangement according to the second embodiment, or the light source of the arrangement according to the first embodiment, can be a matrix LED, i.e., a single component that has several emitting surfaces which can be individually controlled. This can be an RGB LED, but also a pixelated white light source with, for example, 320 pixels.Thus, a large number of alternatives are available as a light source for the lighting device according to the invention.

[0048] Furthermore, a vehicle with the arrangement according to the first or second embodiment is provided. The vehicle can be an aircraft, a watercraft, or a land-based vehicle. The land-based vehicle can be a motor vehicle, a rail vehicle, or a bicycle. A truck, a passenger car, or a motorcycle is particularly preferred. The vehicle can also be configured as a non-autonomous, semi-autonomous, or autonomous vehicle.

[0049] An arrangement for a vehicle is provided. This arrangement includes a vehicle component with a visible surface. The surface has a plurality of light-emitting areas that are spaced apart from one another. Furthermore, according to a first embodiment, the arrangement includes a light guide that has at least one simple surface and a plurality of coupling surfaces, wherein each coupling surface of at least a portion of the coupling surface of the light guide is assigned to one of the light-emitting areas. Alternatively, according to a second embodiment, the arrangement includes a plurality of light sources, wherein each coupling surface of each light source is assigned to one of the light-emitting areas of at least a portion of the light sources. A vehicle is also provided.

[0050] The invention will now be explained in more detail using exemplary embodiments. The figures show: Fig. 1 a top view of an arrangement according to a first or second embodiment, Fig. 2 a perspective view of a light guide of the arrangement according to the first embodiment, Fig. 3 a perspective view of a light guide according to a further embodiment, Fig. 4a a perspective view of an output coupling structure of the optical fiber, Fig. 4b a perspective semi-transparent view of an output coupling structure according to a further embodiment of the light guide, Fig. 5a an exploded view of the arrangement according to the second embodiment, Fig. 5b an arrangement of Fig. 5a in assembled state, Fig. 6 a perspective view of a light guide according to a further embodiment with an image mask, and Fig. 7 a photograph emitted by an arrangement according to the first or second embodiment.

[0051] Fig. Figure 1 shows an arrangement 1 according to the first or second embodiment, which is arranged on a vehicle 2, indicated here by a dashed line. The arrangement 1 includes a vehicle component 4, which in this embodiment is a radiator grille. The vehicle component 4 has a surface 6 visible to an observer when viewing the vehicle 2 from the outside.

[0052] Vehicle component 4 has a lattice structure. Vehicle component 4 has a central recess 8 for, for example, a brand logo and / or other markings. Lattice struts 10, extending in a first direction, are adapted to the curvature of the recess 8. That is, they are curved so that lattice struts 10 located near the recess 8 partially enclose it and are arched. The further away from the recess 8 the respective lattice struts 10 are arranged, the less curved they are. Lattice struts 12, extending perpendicular to the lattice struts 10, are approximately parallel to each other and aligned straight. Preferably, the lattice struts 10 extend approximately vertically and the lattice struts 12 approximately horizontally. For clarity, only one lattice strut of each of the lattice struts 10 and 12 is provided with a reference numeral.

[0053] Where the grid struts 10 and 12 intersect, intersection areas 14 are provided, each with a light-emitting area 16. For clarity, only one intersection area 14 and one light-emitting area 16 are each labeled with a reference symbol.

[0054] Each of the light-emitting areas 16 shown here can be associated with a respective coupling surface of a light guide, which is not shown here, and / or a respective light source, which are also not shown here.

[0055] Fig. Figure 2 shows an optical fiber 18 comprising a base optical fiber 20 and, in this example, three branch optical fibers 22. The base optical fiber 20 is cylindrical, in particular with a circular cross-section, and extends in a straight line. The branch optical fibers 22 are also each cylindrical, in particular with a circular cross-section, and extend from the base optical fiber 20 in a common direction at regular intervals. The branch optical fibers 22 extend at an angle of 90° from the base optical fiber 20 and are arranged parallel to each other.

[0056] The base optical fiber 20 has a coupling surface 24 into which light from a light source (not shown) can be coupled. The coupling surface 24 is located on one of the base faces of the cylindrical base optical fiber 20. The base optical fiber 20 also has another coupling surface 26 located on the other base face. Therefore, the coupling surface 26 could be closed (e.g., as a mirror to "recycle" the light) or used as an output coupling surface.

[0057] The branch optical fibers 22 each have a respective coupling surface 28, which in this embodiment are arranged in a common plane and are each located on a base surface of the respective cylindrical branch optical fibers 22. In this embodiment, the branch optical fibers 22 are uniformly designed. However, it is also possible for the branch optical fibers 22 to project, for example, in different directions and / or have different shapes and / or project to different distances from the base optical fiber.

[0058] In Fig. Figure 3 shows another embodiment of an optical fiber 30. This has a grid-shaped base optical fiber 32, with branch optical fibers 36 formed at the respective intersection regions 34 of the grid-shaped base optical fiber 32, projecting perpendicularly from the base optical fiber 32 in the same direction. The grid structure of the base optical fiber 32 is square and symmetrical. That is, the base optical fiber 32 has several, here five, grid struts that are arranged parallel to each other and extend at regular intervals in an X-direction. Several, here five, further grid struts extend perpendicular to the other grid struts. They also have regular intervals in a Y-direction and are arranged parallel to each other. Each grid strut of the base optical fiber 32 is, as in the embodiment shown in Figure 3, Fig. 2, cylindrical, in particular with a circular cross-section. That is, each lattice strut of the lattice-shaped base light guide 32 has a round cross-section. The branch light guides 36 are designed accordingly, like the branch light guides 22 of the Fig. 2 formed. That is, these collars extend cylindrically from the base light guide 32 at the intersection areas.

[0059] At each end of a lattice strut of the lattice-shaped base light guide 32, a coupling surface 38 can be arranged; however, only one coupling surface 38 is designated with a reference numeral here. It is also possible that only some of the ends of the lattice struts and / or only one end of a lattice strut of the base light guide constitutes a coupling surface 36. The branch light guides 36 each have an output coupling surface 40 at their end. For clarity, only one output coupling surface 40 is designated with a reference numeral.

[0060] In this embodiment according to Fig. 3 the light guide 30 is designed such that the brightness of the light coupled out from the respective coupling surfaces 40 gradually decreases in the Y direction and is constant in the X direction.

[0061] Fig. Figure 4a shows a part of a basic optical fiber, for example the basic optical fiber 20 of the Fig. 2, and a branch optical fiber, for example the branch optical fiber 22 of the Fig. 2. The base optical fiber 20 has a round cross-sectional shape with a flattened side, the flattened side being a longitudinal side facing away from the side from which the branch optical fiber 22 couples out. A coupling structure 41 is formed in the flattened side of the base optical fiber 20. This is advantageous because the coupling structure 41 can thus be easily inserted.

[0062] The output coupling structure 41 is a prism-like, wedge-shaped, or ramp-shaped recess configured as an optical prism or reflection prism. The output coupling structure is formed in the base optical fiber 20 on a longitudinal side facing away from the side from which the branch optical fiber 22 projects. The output coupling structure 41 has at least one prism surface from which the light, which couples in via the input surface 24 (not shown here), is at least partially reflected, so that it couples at least partially into the branch optical fiber 22. This prism surface extends from the flattened side of the base optical fiber 20 into the base optical fiber 20 in the direction of the branch optical fiber 22. The output coupling structure 41 is specifically configured such that light coupling into the input surface 24 partially strikes the prism surface.Therefore, the coupling structure 41 can only penetrate a portion of the cross-section of the base optical fiber 20. This means that the coupling structure 41 enables light to be coupled from the base optical fiber 20 into the branch optical fiber 22. Depending on the configuration of the coupling structure 41—that is, how far the prism surface projects towards the branch optical fiber 22 and what angle the prism surface has with the flattened side of the base optical fiber 20—a varying amount of light can be coupled into the branch optical fiber 22.

[0063] Fig. Figure 4b also shows the base optical fiber 20, from which the branch optical fiber 22 projects. In this embodiment, the base optical fiber 20 has a coupling structure 42. The coupling structure has a surface 46 from which the light in the base optical fiber 20 is partially reflected. The surface 46 extends from a side of the base optical fiber 20 that faces away from the longitudinal side from which the branch optical fiber 22 projects, towards the branch optical fiber 22. The surface 46 is generated, in particular by a laser. The laser can, for example, create the surface 46 as an internal engraving in the base optical fiber 20. The internal engraving can, for example, consist of a multitude of gas bubbles and thus form a scattering center. Due to the material transition and the difference in refractive index between the base optical fiber and the gas bubbles, light can be reflected by them.This means that light striking surface 46 is diffusely reflected from it and coupled into the branch optical fiber 22. Surface 46 does not extend through the entire cross-section of the base optical fiber 20 to the branch optical fiber 22, so that not all the light strikes surface 46.

[0064] Fig. Figure 5a shows a light source 50, which is part of the arrangement 1, which is in Fig. Figure 1 is shown. In this embodiment, the light source 50 is an LED on a circuit board 54. The light source 50 has a coupling area 56 which corresponds to one of the light-emitting areas 16 shown in Figure 1. Fig. Figure 1 shows the following: The light emitted from the output coupling surface 56 couples into an optical fiber 58, which is an optical element. The optical fiber 58 is cylindrical and extends straight and perpendicular to the output coupling surface 56 of the light source 50. The light coupling into the cylindrical optical fiber 58 is guided through it to an output coupling surface 60 of the optical fiber 58. The light coupling out from the output coupling surface 60 can couple into an element, which is optically active and in this case is a diffuser 62. The cylindrical diffuser 62 has a circular cross-sectional area and the same diameter as the cylindrical optical fiber 58 and is arranged on the output coupling surface 60. The diffuser and the optical fiber 58 are arranged coaxially with each other.

[0065] Furthermore, in the Fig. 5a An image mask 64, which in this embodiment is designed as a cap, is arranged. That is, the image mask 64 is hollow cylindrical with a base and can be placed or inserted over the light guide 58 and the diffuser 62. A recess 66 is provided in the image mask 64 through which the light exits. The recess 66 is formed in the base of the image mask 64. In other words, the image mask 64 is lid-shaped, with the recess 66 provided in a lid base.

[0066] In Fig. 5b is a further embodiment in contrast to the Fig. 5a of an image mask 67 shown. As in Fig. As shown in Figure 1, a plurality of light-emitting areas 16 are preferably located on the visible surface 6, which are in Fig. As shown in Figure 1, the image mask 67 is arranged side by side. Each light-emitting area 16 can be assigned a light source 50. To facilitate and speed up the assembly of the image mask 67, the image mask 67 can have a plurality of caps, which are designed as shown in Figure 1. Fig. 5a. The caps are connected by bridges so that they have a predetermined and suitable distance to be easily attached to the light guides 58, which are arranged next to each other, or to hold the light guides (e.g., if the grid 4 or 14 already contains the caps 67, or if the caps 67 are part of component 4). Fig. 5b shows only a light source 50 with a light guide 58 for the sake of simplicity.

[0067] In Fig. Figure 6 shows a further embodiment of an optical fiber 68, which has a base optical fiber 70 and a branch optical fiber 72. The base optical fiber 70, which essentially has a cylindrical shape with a circular cross-section, is flattened on its longitudinal side facing away from the branch optical fiber 72. The branch optical fiber 72 is cylindrical. A coupling surface 74 of the branch optical fiber 72 has a projection 76, which in this embodiment is star-shaped. Furthermore, an image mask 78 is provided, which, like the image mask 66 of the Fig. 5a is formed. That is, the image mask 78 also has a recess 80. This is star-shaped. The image mask 78, which is cap-shaped, can be placed or inserted over the coupling surface 74 of the light guide 72, and the star-shaped protrusion 76 then projects through the star-shaped recess 80 over the image mask 78.

[0068] In Fig. Figure 7 is an example of a photographic image that can be emitted by an arrangement which, for example, includes the optical fiber 30 of the Fig. 3, wherein coupling surfaces 40 of the branch optical fibers 36 in this example each have an image mask 64 which are located in the Fig. 5a and Fig. 5b are shown, are equipped to emit the respective star-shaped light patterns.
