Description

Technical Field

[0001] This invention relates to a lighting device for motor vehicles. Background Technology

[0002] A lighting device configured as a headlight for a motor vehicle is known from DE102021122953B3. The lighting device described therein includes: a plurality of light sources from which light is emitted during operation of the lighting device; a collimating optics comprising a plurality of collimating lenses, each having an incident surface and an exit surface, through which light emitted by the light sources passes; and a secondary optics comprising a plurality of arrays of cylindrical lenses, wherein light emitted by the collimating optics passes through the arrays of cylindrical lenses, wherein the collimating lenses are arranged in at least two rows, wherein in each row, at least two collimating lenses are arranged side-by-side along a first direction, and wherein the rows are arranged side-by-side along a second direction preferably perpendicular to the first direction. By using the three overlapping rows disclosed in DE102021122953B3, high beam, front portion of low beam, and range portion of low beam can be generated as different primary beam functions.

[0003] For the signaling functions of motor vehicles, such as taillights, brake lights, directional indicators, or daytime running lights in taillight assemblies or headlights, design has long been a decisive factor. Since the introduction of LED technology, the design of these lighting devices has become even more important because small light-emitting diodes, often used in larger quantities, can be used much more flexibly as signaling lighting devices than large incandescent bulbs, thus offering a wide range of design possibilities when combined with the chosen optical system.

[0004] A variant of LED technology exists in the form of OLED technology, in which the lighting device is not small like a dot in a light-emitting diode, but is constructed in a larger, planar shape to form a desired light-emitting surface that can be illuminated very uniformly. In OLED technology, the significantly higher cost compared to LED technology proves to be a disadvantage. This high cost is due to the complex manufacturing process, the different molding processes predetermined by the design, and the small part quantity. This presents particularly high requirements in the automotive field, such as durability under UV loads and forces like vibration, shock, and sway, as well as heat resistance in the range of -40°C to +85°C or +100°C. These requirements are significantly more difficult to meet for organic light-emitting diodes than for standard light-emitting diodes.

[0005] This leads to the search for alternative possibilities to achieve a similar structure as that using organic light-emitting diodes (OLEDs), i.e., especially a surface that is uniformly illuminated. This is achieved by using light-emitting diodes (LEDs) comprising a planar light conductor and a front-mounted optical system in the form of a microstructured film or thin optical sheet to scatter light emitted from the light conductor. Overall, this provides a flat-light-moduloid that offers high performance when uniformly illuminating the entire surface.

[0006] Just as in organic light-emitting diodes, multiple flat light modules can be staggered and positioned side by side and sequentially when integrated into taillights to produce the desired personalized appearance for signal functions, such as taillights or tail brake lights.

[0007] A lighting device of the type described at the beginning, configured as a flat light module, is known from DE102021122264A1. The lighting device described therein has multiple light sources configured as light-emitting diodes (LEDs) and a planar light conductor including an incident surface and at least one exiting surface, wherein the incident surface is configured as the end face of the light conductor. The lighting device further has two optical plates, each having at least one structured portion, through which light emitted from the exiting surface passes sequentially. Here, the structured portion of the second optical plate along the light propagation direction is formed by an array of roof prisms, which are arranged side-by-side along a first direction and extend parallel to each other along a second direction perpendicular to the first direction. Each of the roof prisms has two inclined side faces, the ends of which form connecting edges extending along the second direction, wherein the side faces form 90° ridge angles with each other in the connecting edges.

[0008] An exemplary lighting device according to the prior art, which is composed of a flat light module, consists of... Figure 10 and Figure 11 As can be seen, the flat optical module has a light source 1, which has multiple light-emitting diodes (LEDs). The flat optical module also has a housing 2 comprising front and rear housing components 2a and 2b, which are interconnected by locking mechanisms. Between the housing components 2a and 2b, a plate-shaped light conductor 3 including micro-optical devices, a white diffuse-reflecting film 4 behind the light conductor 3, and two or three optical components 5a and 5b, which are composed of micro-optical films, are introduced in front of the light conductor 3. These micro-optical components coordinate with each other, and together they are responsible for the light distribution and efficiency of the system. The principle of this basic construction is to provide a light-emitting element comprising a surface uniformly illuminated. For this purpose, the lighting device has a shielding cover 6, which serves as the illuminated exit surface of the lighting device.

[0009] Here, the optical component 5a adjacent to the light conductor 3 is configured as a diffuser, while the second optical component 5b is configured as a so-called BEF optics device. BEF here stands for "Brightness Enhancement Film." That is, the BEF optics device is used to increase the brightness of light passing through the optical component 5b. The BEF optics device can be implemented on a film or as a thin injection-molded optical sheet. A system comprising two BEF optics orthogonally oriented to each other can also be provided, where the diffuser optics are sometimes omitted.

[0010] Today's primary beam functions, such as low beam and / or high beam, are mostly fixed, modular configurations that can only be slightly modified. These include large, visible optics with predetermined curvature and external reflections. Furthermore, these modules must be adjusted vertically, laterally, and typically relative to each other. This movement is difficult to reconcile with current design trends.

[0011] Because signal light functions are significantly more flexible in their construction within lighting installations that combine main and signal light functions, modules for main functions such as low beams and / or high beams are often placed in a separate and more concealed area. Therefore, in most cases, the flexible and constructible area for signal light functions can dominate. However, in situations involving shady driveways or darkness, the main light function must be forced into use. The resulting warm-toned appearance strongly and disruptively deviates from the original design concept. For this reason, it is desirable to adapt the daytime and nighttime appearances of lighting installations with both main and signal light functions to each other. Several different approaches exist behind the idea of ​​identical daytime and nighttime appearances. An optimized approach would be a 100% identical daytime and nighttime appearance without deviation, but the primary desire is the possibility of integrating the main light function. Summary of the Invention

[0012] Therefore, the problem upon which this invention is based is to provide a lighting device of the type described at the beginning, which can produce at least one main light function and at least one signal light function, wherein the daytime appearance and the nighttime appearance are adapted to each other, and in particular, identical to each other.

[0013] This is achieved according to the invention by a lighting device of the type described at the beginning having the features of claim 1. The dependent claims relate to preferred designs of the invention.

[0014] According to claim 1, the lighting device comprises:

[0015] - At least one main optical module for generating at least a portion of low beam and / or high beam, wherein the at least one main optical module has at least one light source, a main optics element, and a secondary optics element, wherein the at least one main optical module is designed to allow light emitted by the at least one light source to pass through the main optics element and through the secondary optics element.

[0016] - At least one signal light module for generating at least one signal light function, wherein the at least one signal light module has at least one light source, a planar light conductor including an incident surface and at least one exit surface, and at least one optical component, wherein the at least one optical component is configured as an optical sheet or optical film, wherein the at least one signal light module is designed such that light emitted from the at least one light source is incident on the incident surface of the planar light conductor, exits from the at least one exit surface of the planar light conductor, and at least partially penetrates through the at least one optical component and / or is reflected by the at least one optical component, and

[0017] - An additional optical component, the optical component being configured as an optical sheet or optical film and having an incident surface and an exit surface, wherein a structure is provided on the incident surface and / or exit surface of the additional optical component, and wherein the additional optical component is arranged in the illumination device such that, during operation of the illumination device, light generated by the at least one main optical module and the at least one signal optical module penetrates through the additional optical component.

[0018] The daytime appearance of the lighting device can be matched with its nighttime appearance through the at least partially structured additional optical components, because not only light from at least one primary light function but also light from at least one signal function penetrates through the structured additional optical components. Here, the structured additional optical components form, in particular, a continuous, seamless output coupling optics. Furthermore, the structured additional optical components, serving as the output coupling optics, prevent adjustment movements of the module from being visible from the outside.

[0019] Furthermore, the structured additional optical components used as output coupling optics create a uniform appearance in the region where the main light function is generated and the region where the signal light function is generated, even when the lighting device is off. Moreover, by providing these structured additional optical components, the size, profile, profile, and tilt of the output coupling optics can be selected with considerable freedom. In particular, these structured additional optical components used as output coupling optics can extend across the entire front of the vehicle. Furthermore, the structured additional optical components used as output coupling optics allow for flexible feature markings, as individual areas can be further connected or disconnected behind them. Additionally, the additional optical components provide the possibility of generating a complete black panel appearance when needed.

[0020] The structure disposed on the incident and / or exit surfaces of the additional optical component can be strip-shaped, particularly wherein the strip-shaped structure is designed to allow light passing through the strip-shaped structure to propagate horizontally in the state where the lighting device is installed in the vehicle. For example, the strip-shaped structure of the additional optical component can be formed by cylindrical lenses arranged side-by-side along a first direction corresponding to the horizontal direction in the state where the lighting device is installed in the vehicle, wherein the cylindrical axis of the cylindrical lenses extends along a second direction corresponding to the vertical direction in the state where the lighting device is installed in the vehicle. By propagating light passing through the additional optical component horizontally, the optical component assists in the horizontal propagation required by the lighting function. Thus, for example, the main beam module generating high beams no longer needs components for horizontal propagation.

[0021] It is possible that the at least one main optical module has multiple light sources and the main optical device of the at least one main optical module is configured as a collimating optical device including multiple collimating lenses, each of which has an incident surface and an exit surface, and the light emitted by the light source passes through the incident surface and the exit surface in sequence.

[0022] The at least one primary optical module's secondary optics can be configured such that it has a transparent first substrate comprising an incident surface and an exit surface, wherein a structure is provided on the incident and / or exit surface of the first substrate, the structure being designed to shape light passing through the structure vertically in the state where the lighting device is installed in the vehicle, particularly wherein the first substrate is designed to generate horizontal light-dark boundaries and / or a gradient vertical light distribution. Here, the transparent first substrate of the at least one primary optical module's secondary optics can have at least one irregularly shaped array of cylindrical lenses, particularly wherein the incident surface of the first substrate has multiple input facets of different sizes and wherein the exit surface of the first substrate has multiple output facets of equal size. Such a configuration can effectively generate horizontal light-dark boundaries and / or a gradient vertical light distribution.

[0023] Furthermore, the secondary optics of the at least one primary optical module can be configured such that they have a transparent second substrate comprising an incident surface and an exit surface, wherein a strip-shaped structure is provided on the incident surface and / or exit surface of the second substrate, particularly wherein the strip-shaped structure is formed by cylindrical lenses arranged side-by-side along a first direction, wherein the cylindrical axis of the cylindrical lenses extends along a second direction, so that light passing through the strip-shaped structure is horizontally extended in the state of the illumination device installed in the vehicle. Here, the second substrate can be provided for the primary optical module used to generate the front portion of the low beam, while in the primary optical module used to generate the high beam distribution, the second substrate is preferably omitted, because sufficient horizontal extension can be achieved by using additional optical components as output coupling optics.

[0024] The signal optical module can be configured as a flat optical module. It is possible that the at least one signal optical module has first and second optical components, which are respectively configured as microstructured optical films and / or microstructured optical sheets, wherein the at least one signal optical module is designed to allow light emitted from at least one exit surface of the planar light conductor to sequentially pass through the first and second optical components. Here, one of the optical components of the at least one signal optical module, especially the first optical component, may have a diffuser optics and / or one of the optical components, especially the second optical component, may have an array of roof prisms. The diffuser optics can appropriately scatter light to improve the uniformity of illumination. The BEF optics can increase the brightness of light passing through the optical components. The two surfaces or optical components can jointly ensure efficient illumination of the exit surface of the illumination device, such as a shield.

[0025] The at least one signal optical module can be configured such that its planar optical conductor has two opposing exit surfaces, and the at least one signal optical module has a third optical member configured as a surface that is at least partially reflective, the at least partially reflective surface being disposed on the side of the planar optical conductor facing away from the first two optical members. The illumination device is designed to cause light emitted from the exit surface of the optical conductor facing away from the first two optical members to be incident on the reflective surface, reflected back from the reflective surface to the exit surface, and at least partially re-incidentally into the optical conductor, after which the light exits from the exit surface facing towards the first two optical members. By allowing light reflected back from the reflective surface to re-incidentally enter the optical conductor, the effectiveness of the signal optical module is improved.

[0026] It is possible that the illumination device is designed to allow light emitted by the at least one main optical module to travel at least partially through the at least one signal optical module before it incident on the additional optical component. Alternatively or additionally, the illumination device may be designed to allow light emitted by the at least one main optical module to penetrate at least partially through the at least one signal optical module before it illuminates the additional optical component. Here, the at least one optical component of the at least one signal optical module may be designed to allow light emitted by the at least one main optical module to pass through substantially unimpeded, particularly wherein the at least one optical component of the at least one signal optical module has at least one gap and / or at least one unstructured transparent segment to allow light emitted by the main optical module to pass through.

[0027] Furthermore, the planar optical conductor of the at least one signal optical module can be configured to allow light emitted from the at least one main optical module to pass through substantially unimpeded. Here, at least one exiting surface, or at least one of the exiting surfaces, of the planar optical conductor of the at least one signal optical module may be provided with a structured portion, particularly wherein the structured portion is not disposed in at least one segment of the at least one exiting surface, so as to allow light emitted from the at least one main optical module to pass through.

The optical component is configured as an optical sheet or optical film and has an incident surface and an exit surface. The additional optical component 13 is arranged such that, during operation of the lighting device, light generated by the main light modules 10, 11 and the signal light module 12 passes through the additional optical component 13. In its installed state, the additional optical component 13 extends along the lateral direction of the vehicle, particularly substantially across the entire width of the front of the vehicle.

[0042] A strip-shaped structure formed by cylindrical lenses is provided on the incident and / or exit surfaces of the additional optical component 13. The cylindrical lenses are arranged side-by-side along a first direction corresponding to the horizontal direction when the lighting device is installed in the vehicle, wherein the cylindrical axis of the cylindrical lenses extends along a second direction corresponding to the vertical direction when the lighting device is installed in the vehicle. The strip-shaped structure is designed to cause light passing through it to spread horizontally when the lighting device is installed in the vehicle. The spread caused by the strip-shaped structure can be approximately ±15°.

[0043] exist Figures 1 to 3 Only the two main light modules 10 and 11 on the left side of the vehicle are depicted. Two other main light modules 10 and 11 are correspondingly arranged on the right side of the vehicle. Here, on both sides, the second main light module 11 is further outward than the first main light module 10.

[0044] exist Figure 4 and Figure 5 The image depicts a first main beam module 10. This first main beam module 10 is used to generate high beam. The first main beam module 10 has a plurality of light sources 14 arranged spaced apart from each other along a second direction or along a vertical direction, the light sources being configured as light-emitting diodes (LEDs) (see [link]). Figure 5 The first main optical module 10 further includes a collimating optical device comprising a plurality of collimating lenses 15, each having an incident surface and an exit surface, which serve as the main optical device. The collimating lenses 15 are also spaced apart from each other along a second direction or along a vertical direction. Here, one of the collimating lenses 15 is configured for each of the light sources 14, such that light emitted from one of the light sources 14 sequentially passes through the incident surface and exit surface of the configured collimating lens 15.

[0045] The first primary optical module 10 further includes secondary optics, which have a transparent first substrate 16 including an incident surface 17 and an exit surface 18, wherein structures are respectively provided on the incident surface 17 and the exit surface 18 of the first substrate 16. Here, the first substrate 16 has at least one array of irregularly shaped cylindrical lenses, wherein the incident surface 17 of the first substrate 16 has a plurality of input facets 19 of different sizes and wherein the exit surface 18 of the first substrate 16 has a plurality of output facets 20 of the same size (see...). Figure 8 and Figure 9 ).

[0046] The first substrate 16 is designed to shape transmitted light vertically in the state of the lighting device installed in the vehicle, and in particular, the first substrate 16 of the first main light module 10 is designed to generate a gradient vertical light distribution. The horizontal shaping of the light emitted by the first main light module 10 is achieved by an additional optical component 13, which causes horizontal expansion in the state of the lighting device installed in the vehicle.

[0047] exist Figure 6 and Figure 7 The image depicts a second main optical module 11. This second main optical module 11 is used to generate at least a portion of the near light distribution, wherein the second main optical module 11 is particularly used to generate the front portion of the near light distribution.

[0048] As in the first main optical module 10, the second main optical module 11 also has multiple light sources 14 and collimating optics including multiple collimating lenses 15, which serve as main optics. The light sources 14 and collimating optics are constructed similarly to those in the first main optical module 10.

[0049] The second main optical module 11 further includes secondary optics comprising a transparent first substrate 16 and a transparent second substrate 21, through which light emitted by the collimating optics can sequentially pass. Here, the first substrate 16 is constructed similarly to that in the first main optical module 10, wherein the first substrate 16 of the second main optical module 11 is specifically designed to generate horizontal light and dark boundaries.

[0050] A strip-shaped structure formed by cylindrical lenses is provided on the incident and / or exit surfaces of the second substrate 21. The cylindrical lenses are arranged side-by-side along a first direction, with their cylindrical axes extending along a second direction, so that light passing through the strip-shaped structure is horizontally propagated when the illumination device is installed in the vehicle. Here, an additional optical component 13 achieves a final propagation of the light emitted from the second main optical module 11 to approximately ±40°.

[0051] The signal optical module 12 has at least one light source (not depicted) and a planar light conductor 22 including one incident surface and two exit surfaces. Here, the incident surface is located on the light conductor 22... Figure 1 On the lower end side. Figure 1 The front face and in Figure 1 The face behind the middle is used as a projecting surface. Here, in Figure 1 The rear exit surface can be structured at least locally so as to achieve preferred output coupling of light moving through the optical conductor 22 via the front exit surface.

[0052] Multiple light sources, configured as light-emitting diodes (LEDs), can be arranged side-by-side along the lateral direction of the vehicle. These LEDs can also have different colors, for example, to achieve dual or triple functions. For example, LEDs with red and yellow, white and yellow, or white and cyan colors, or dual-color LEDs or RGB LEDs, are possible. The functions could be, for example, position lights, daytime running lights, and driving direction indicators, or position lights, daytime running lights, and an autonomous driving function, wherein the autonomous driving function requires cyan.

[0053] The signal optical module 12 further includes first and second optical components 23 and 24, which are respectively configured as microstructured optical films and / or microstructured optical sheets. Here, the signal optical module 12 is designed to allow light emitted from at least one exit surface of the planar light conductor 22 to sequentially pass through the first and second optical components 23 and 24. The first optical component 23 has a diffusion optics element. The second optical component 24 has an array of at least one roof prism. The array of roof prisms serves as a BEF optics element.

[0054] The signal optical module 12 further includes a third optical component 25, which is configured as a surface that is at least partially reflective. This surface is disposed on the side of the planar light conductor 22 opposite to the first two optical components 23 and 24. Here, the illumination device is designed so that light emitted from the exit surface of the light conductor 22 opposite to the first two optical components 23 and 24 is incident on the reflective surface of the third optical component 25, reflected back to the exit surface, and at least partially incident again into the light conductor 22. Thereafter, the light exits from the exit surface facing the first two optical components 23 and 24.

[0055] The illumination device is designed such that light emitted by the second main optical module 11 travels through the signal optical module 12 before it is incident on the additional optical component 13 (see for details). Figure 2 ).

[0056] The illumination device is further designed to allow light emitted by the first main optical module 10 to pass through the signal optical module 12 before it is incident on the additional optical component 13 (see for details). Figures 1 to 3 In order to enable light to pass through the signal optical module 12 as unobstructed as possible, the optical components 23, 24, and 25 of the signal optical module 12 each have a gap 26 (see...). Figure 1 Furthermore, no optical conductor is provided in the section aligned with the gap 26.
