Description

Technical Field

[0001] This invention relates to a lighting module for use in a lighting device for vehicles. Furthermore, this invention relates to a method for manufacturing the lighting module and a lighting device for vehicles. Background Technology

[0002] Manufacturing and assembly tolerances in the manufacture of lighting devices for vehicles (e.g., automotive headlights) necessitate providing sufficient structural space for orienting the different components and / or structural assemblies relative to each other. This can be configured such that optical units, which may contain light-forming elements (e.g., lenses), must be positioned in a predefined orientation relative to one or more light sources to produce a desired light pattern or achieve desired light incidence into one or more optical units. Alternatively, the light source and / or optical unit can be positioned in a predetermined orientation relative to a light shield or other component, thereby enabling light emission from a predetermined gap (light emission opening) in the light shield with desired quality. In assembling the lighting device or subsequent structural assemblies, each assembly step or each component or structural assembly is subject to specific manufacturing and / or assembly tolerances. These tolerances can accumulate into a total tolerance (tolerance chain) during assembly as tolerances are passed from subsequent or preceding work steps, which must ultimately be considered when designing the corresponding lighting device.

[0003] Correspondingly, it is necessary to provide the possibility of adjusting the corresponding positioning and / or orientation in the various components and / or structural assemblies of the vehicle's lighting device during assembly, so that an acceptable quality product can always be achieved despite the corresponding manufacturing and / or assembly tolerances. Providing this possibility of adjusting the various components and / or structural assemblies ultimately requires providing structural space reserves, which can adversely affect the size, weight, material requirements, and operability of the lighting device for the vehicle.

[0004] It is also known regarding lighting devices for vehicles that multiple light-forming optical units must be oriented relative to each other in a defined manner to produce a predetermined overall light pattern (e.g., high beam or low beam). Tolerances in the assembly or relative positioning of the optical units can ultimately lead to relative shifts in the light field generated by the respective optical units and unintentionally alter the overall light pattern produced by the lighting module. Summary of the Invention

[0005] Therefore, the objective of this invention is to at least partially overcome at least one of the aforementioned disadvantages. In particular, the objective is to at least partially disrupt the tolerance chain in the manufacture and / or assembly of lighting devices, thereby reducing the total tolerances and required structural space of the lighting equipment. Furthermore, the objective is to at least partially simplify the construction of the lighting equipment while simultaneously enabling flexible construction of the light pattern of the lighting equipment.

[0006] The aforementioned task is solved by the lighting module, lighting device, and method of manufacturing the lighting module of the present invention for use in a lighting device for a vehicle. The features and details described herein in connection with the lighting module according to the invention are also applicable to the lighting device and / or the method according to the invention, and thus, the disclosures regarding various aspects of the invention are always mutually referenced or can be mutually referenced.

[0007] According to the present invention, a lighting module for use in a lighting device for vehicles, particularly automobiles, is provided, comprising a light source unit, at least one first optical unit, particularly a shaping light unit, and at least one second optical unit, particularly a shaping light unit, and at least one support element. The light source unit has at least one light source, and at least the first and second optical units are fixedly positioned on the support element. Furthermore, according to the present invention, at least one first reference mark is provided on the first optical unit, and at least one second reference mark is provided on the second optical unit. The first and second reference marks are configured such that the relative positional movement between the first and second optical units can be determined by detecting at least the first and second reference marks.

[0008] In other words, the relative positional movement between the first and second reference marks can be determined by detecting the position and orientation of the first reference mark on the first optical unit and the position and orientation of the second reference mark on the second optical unit, wherein the relative positional movement between the first and second reference marks represents the relative positional movement between the first and second optical units. It is conceivable that the relative positional movement includes translational and / or rotational misalignments between the first and second reference marks, or that the reference marks are configured such that not only translational misalignments but also rotational misalignments can be detected between the first and second reference marks.

[0009] The detected relative positional movement between the first and second reference marks can be subsequently compensated for by a misalignment of rotation and / or translation between the first and second reference marks with a corresponding theoretical or reference value (theoretical positional movement). The deviation between the detected positional movement and the theoretical positional movement can then be used to determine the machining position on at least one optical unit.

[0010] The processing location here refers to the location where the surface of the component and / or the coating applied to the component is processed. The processing can be laser processing and / or cutting. The processing location can be described as a point or coordinate system, and processing is then performed at least at that point, particularly in a locally defined area surrounding that point. The processing location on the optical unit is preferably a location on the optical unit where free laser processing should be performed on the opaque coating of the optical unit. In other words, the processing location can be a position on the surface of the optical unit where the opaque coating on the optical unit should be removed by laser processing in a locally defined area surrounding the processing location, so that light input to the optical unit can be achieved at that location, thus providing a light incident opening on the optical unit.

[0011] The present invention generally offers the advantage that the location of localized light incident within the optical units can be determined by the relative positioning of at least two optical units relative to each other. This allows the locations of light incident in individual or all optical units mounted in the illumination module to be adapted after the optical units are arranged on one or more support elements, such that the superposition of the light fields generated by the optical units ultimately results in the desired overall light pattern of the illumination module. Whereas, if the location of light incident within the optical units is determined before the optical units are positioned on the support elements, deviations caused by tolerances in the relative positioning of the optical units relative to each other will inevitably lead to variations in the overall light pattern of the illumination module. Therefore, it generally offers the advantage that tolerances in the relative positioning of multiple optical units relative to each other can be at least partially compensated, because the tolerance chain is broken and the tolerances to be considered in the positioning of the optical units are not or substantially not further propagated.

[0012] Within the scope of this invention, it is conceivable that at least one light source unit, and in particular all light source units, are fixedly disposed on at least one support element. It is also conceivable that at least one light source of at least one light source unit is an LED.

[0013] Within the scope of this invention, the optical unit has one or more lens elements and functions to shape light. The optical unit has one, in particular exactly one, light-incident side (or coupling side) and one, in particular exactly one, light-outceasing side (or coupling side) with respect to its orientation in the application of the arrangement. That is, the light-incident side is the side of the optical unit on which light enters the optical unit corresponding to the application of the arrangement, and the light-outceasing side of the optical unit is the side on which light exits the optical unit corresponding to the application of the arrangement. The light beam entering on the light-incident side is at least partially altered in direction by the optical unit, so that at least a portion of the light beam entering the optical unit on the light-incident side has a changed direction relative to the light-incident side on the light-outceasing side. For this purpose, the optical unit has at least one lens element or multiple lens elements, in particular those with identical structures. The corresponding light-incident side of the lens element forms the light-incident side of the optical unit, and the corresponding light-outceasing side of the lens element forms the light-outceasing side of the optical unit.

[0014] A fixed-position arrangement here refers to an assembly or arrangement where relative movement between the relevant components (e.g., optical units) and the support elements is no longer possible. The relevant components, immediately following the fixed-position arrangement, can therefore only move indirectly through the movement of the support elements, excluding relative movement between the components and the support elements, and between the components and other components (e.g., other optical units) fixedly mounted on the support elements. This results in the advantage that accidental movement of the optical units and the resulting changes in the light image of the illumination module can be avoided.

[0015] Within the scope of this invention, it is also conceivable that the illumination module according to the invention has three, particularly four, preferably five, or preferably more than five, particularly shaping light optical units, wherein at least one reference mark is provided on each of the optical units and the optical units are, in particular, fixedly positioned on at least one, particularly exactly one, support element, thereby preventing relative movement between the optical units. Here, it is conceivable that by detecting at least one reference mark of each optical unit, the relative positional movement between all the optical units can be determined. Therefore, at least one processing position on at least one optical unit can be determined based on the determined positional movement.

[0016] Furthermore, it is conceivable that at least two optical units, and in particular all optical units, of the illumination module are preferably arranged in a common plane with respect to their respective light incident surfaces. In other words, it can be configured such that the light incident surfaces of at least two optical units of the illumination module are not misaligned with respect to the main emission direction of the illumination module. This results in the advantage of a simpler determination of the relative positional movement between the individual optical units. The relative positional movement between two optical units can therefore be described by a misalignment of translation in the common plane and a misalignment of rotation in the common plane, wherein, in particular with respect to rotational misalignment, the corresponding rotational axes of the reference numerals are commonly perpendicular to the plane.

[0017] Within the scope of this invention, it is conceivable that the support element be implemented in multiple parts. The components of this support element can preferably be interconnected in such a way that relative movement between the components is impossible. In other words, it can be configured such that the support element forms a fixed structure, and other components, particularly one or more optical units, can be fixedly mounted on said structure. The support element can be at least partially constructed as a profile, frame, or tie rod. It is also conceivable that the support element is constructed as a monolithic, particularly uniform, component.

[0018] Within the scope of this invention, at least one optical unit, and in particular all optical units, can be configured to be form-locked and / or force-locked and / or reversibly connected to at least one support element. In other words, at least one optical unit can be connected to at least one support element such that the connection between the optical unit and the support element can preferably be disengaged without damage. In particular, the connection between the optical element of at least one optical unit and the at least one support element can be formed by a threaded connection or a clip connection. This results in the advantage that faulty or defective optical units can be easily and flexibly replaced without damaging other components.

[0019] Furthermore, within the scope of the invention, at least one reference mark of at least one optical unit can be configured such that the at least one reference mark is detectable by optical and / or tactile measurements of the optical unit. It is conceivable that at least one reference mark of at least one optical unit protrudes at least partially from and / or is at least partially incorporated into the surface of the optical unit, i.e., forming a recess. It is also conceivable that at least one reference mark of at least one optical unit is at least partially stained such that it is optically distinguishable from the surface of the optical unit. It is also conceivable that the reference mark has at least partially reflective properties that deviate from the surface of the optical unit surrounding the reference mark. This achieves the advantage that the reference mark of the optical unit can be reliably and definitively detected within the scope of a preferably automated optical and / or tactile measurement process.

[0020] It is also conceivable within the scope of this invention that all reference marks on an optical unit and / or all reference marks on all optical units are implemented identically. This results in the advantage that the standardized detection of the reference marks is simplified within the scope of preferred automated measurements of one or more optical units.

[0021] It is also possible, within the scope of this invention, that the orientation of at least one reference mark of an optical unit is associated with the orientation of at least one optical axis of the optical unit or with at least one optical axis of the lens element of the optical unit. In other words, it is conceivable that the position and / or orientation of at least one optical axis of the optical unit, or that the reference mark has a defined orientation and orientation relative to at least one optical axis, can be directly derived by detecting the position and / or orientation of the reference mark. This results in the advantage that the orientation of the optical axes of multiple optical units relative to each other can be determined based on the relative positional movement between the reference marks of the respective optical units, and the determination of the desired processing positions on the respective optical units is simplified for this reason.

[0022] Within the scope of this invention, at least one lens element of at least one optical unit preferably has a surface with at least a partially convex shape on the light-emitting side, wherein the focal point of the convex surface is located within the lens element. This achieves the advantage that, through the lens element, imaging is not of a light source that may be positioned behind the lens element, but rather of a light-incident opening (e.g., a gap in an opaque coating) provided on the lens element or optical unit.

[0023] Furthermore, it is conceivable that at least one lens element of at least one optical unit is a rotationally symmetric, preferably spherical or aspherical, collimator lens element. This achieves the advantage that the light beam incident from the light source into the optical unit is at least partially parallel to the main emission direction of the illumination module and, if necessary, simplifies the light shaping downstream (e.g., via a projection module). The rotationally symmetric implementation of the lens provides the advantage of producing a symmetrical light image.

[0024] Similarly, it is conceivable that at least one lens element of the optical unit is implemented non-rotationally symmetrically. This results in the advantage that at least one edge of the light incident opening on the optical unit (e.g., a gap in an opaque coating) can be imaged or imaged through the lens element.

[0025] Within the scope of this invention, it is also conceivable that at least one lens element of at least one optical unit is at least partially made of glass and / or polymer and / or silicone. The use of glass offers the advantage of high resistance to surface damage (e.g., scratches). The use of polymers offers the advantage of particularly low manufacturing cost. The use of silicone offers the advantage of particularly low weight.

[0026] According to the present invention, at least one optical unit may have at least one first and one second lens element. It is conceivable that at least the first and one second lens elements, and especially all lens elements, of the optical unit are identically configured. This results in the advantage of uniform light shaping with respect to the respective light segments generated by the optical unit.

[0027] It is also conceivable that at least two, preferably all, lens elements of at least one optical unit are at least partially interlocked and / or irreversibly connected to each other and / or form an integral, especially at least locally material-consistent, component. This achieves the advantage that multiple lens elements of the optical unit are combined into a common structural assembly, reducing the susceptibility to errors in the positioning of individual lens elements within the optical unit and simplifying the operation of the lens elements.

[0028] Also within the scope of the invention, it is conceivable that at least one lens element of at least one optical unit, and in particular multiple or all lens elements of at least one optical unit, form at least partially, preferably completely planar, light incident surface of the optical unit. It is also possible, according to the invention, to provide at least one reference mark on at least one optical unit, particularly on the planar light incident side. This results in the advantage that, in the case of desired processing on the light incident side of the optical unit, the optical unit can be processed directly and without changes in its positioning after detecting the reference mark or other reference marks of other optical units, thereby producing an efficient manufacturing or assembly process.

[0029] Furthermore, according to the invention, an opaque coating can be provided at least partially on at least one optical unit, particularly on the light-incident side of a plane. It is conceivable that the opaque coating is deposited onto the light-incident side of the optical unit. Furthermore, it is conceivable that at least one, particularly multiple, light-incident openings or gaps are provided in the opaque coating of at least one optical unit, particularly all optical units, to enable particularly locally defined light incidence into said optical unit, particularly into at least one lens element of said optical unit. This achieves the advantage that, through a targeted arrangement of the light-incident openings or gaps in the opaque coating, localized light incidence into the optical unit can be defined, thus affecting the light image generated by the optical unit. The position of the light-incident opening can here be adapted based on the relative positional movement between at least two optical units to compensate for tolerances in the positioning of the optical units.

[0030] Within the scope of this invention, it is conceivable that the light source unit has at least one circuit board and / or at least one cooling body. It is conceivable that at least one, especially multiple, light sources, preferably LEDs, are disposed on a circuit board, wherein a material-locked connection, especially a (brazing) connection, is preferably formed between the light source and the circuit board. This is advantageous due to the efficient operation of the lighting module by using LEDs to generate energy. Furthermore, it is conceivable that the cooling body is disposed on the circuit board. The use of a cooling body provides the advantage that heat emitted by the light source can be effectively dissipated. At least one cooling rib can be formed on the cooling body. This increases the efficiency of heat dissipation by increasing the surface area. It can be configured that the light source and the cooling body are disposed on opposite sides of the circuit board. Also within the scope of this invention, it is conceivable that one of the circuit boards, especially in the immediate vicinity of at least one light source or under at least one light source, has at least one through-contact connection that functions as a thermal bridge. This improves the efficiency of heat transfer from the light source to the cooling body.

[0031] Furthermore, it is conceivable that at least one optical unit and at least one light source, or at least one light source unit, are positioned relative to each other such that at least one light source is disposed on the light incident opening of the optical unit. The arrangement on the light incident opening or gap here refers to, with respect to the observation direction along the main emission direction of the illumination module, the projection surface of the LED at least partially, especially substantially, and preferably completely, covers the surface of the light incident opening or gap. This results in the advantage that a majority of the light emitted by the light source is incident into the light incident opening of the optical unit.

[0032] It can be configured such that at least one edge of at least one light-incident opening or gap in the opaque coating of the optical unit is at least partially, and in particular completely, outside the plane of the projection of a light source disposed on said gap. This results in the advantage that the light distribution emitted with respect to that edge can be produced by the aberrations of said optical unit or at least one lens element of said optical unit with respect to the beam remote from the axis.

[0033] Furthermore, within the scope of this invention, at least one light source can be configured such that, with respect to the main emission direction of the illumination module, it is positioned at a distance between 0 mm and 10 mm, preferably between 0 mm and 8 mm, and particularly preferably between 0 mm and 5 mm relative to the light incident surface or light incident opening of the optical unit. At a distance of 0 mm, the light source contacts the surface of the optical unit. Thus, the effect of achieving or enhancing the distribution of emitted light can be similarly achieved with respect to the respective edges of the light incident opening.

[0034] Alternatively, according to the present invention, at least one light source, especially exactly one light source, is provided in the opaque coating of at least one optical unit, especially all optical units, in each light incident opening or gap.

[0035] Within the scope of this invention, it is conceivable to provide at least one projection module, wherein the projection module has at least one lens element and wherein the projection module is positioned on the light-emitting side of at least one optical unit. Furthermore, it is conceivable that the at least one lens element of the projection module is configured as a vertical or horizontal cylindrical lens. By using an additional projection module, there is the advantage of a flexible configuration for producing, for example, light images generated by a lighting module on a road, as well as the possibility of varying the size of the resulting light segments.

[0036] Also within the scope of this invention, it is conceivable that the projection module includes at least one first lens element having a negative focal length and a second lens element having a positive focal length, wherein, in particular, the first lens element is at least partially opposed to the second lens element, and preferably the first and second lens elements are positioned relative to each other such that the focal points of the first lens element and the second lens element coincide. This construction of the projection module provides the advantage that, depending on the dimensional ratio between the focal lengths of the opposing lenses, the size of the section illuminated by the lighting module, for example on a road, can be individually adapted.

[0037] Furthermore, the aforementioned task is solved by a lighting device for a vehicle, wherein the lighting device has at least one lighting module according to the invention. It can be configured such that different light modules of the lighting device each have at least one lighting module according to the invention. Thus, the lighting device can be configured to include a high beam module and / or a low beam module and / or a front zone module, and at least one of the light modules has a lighting module according to the invention.

[0038] Furthermore, the aforementioned task is solved by a method for manufacturing a lighting module for use in a lighting device for vehicles, the lighting device having at least one light source unit, at least one first optical unit and a second optical unit, and a support element, wherein the light source unit has at least one light source. Furthermore, according to the invention, at least one first reference mark is provided on the first optical unit and a second reference mark is provided on the second optical unit, and the following steps are performed, preferably in the given order, within the scope of the method according to the invention:

[0039] The first optical unit is fixed on the support element;

[0040] The second optical unit is fixed to the support element;

[0041] Detecting the first reference mark on the first optical unit;

[0042] Detect the second reference mark on the second optical unit;

[0043] Determine the relative positional movement between the first reference mark and the second reference mark;

[0044] Determine at least one processing position on at least one optical unit;

[0045] At least one optical unit is processed at at least one processing location.

[0046] Within the scope of this invention, it is conceivable that the various steps be repeated and / or performed simultaneously. In particular, it is conceivable that the detection of multiple reference marks on one or more optical units is performed simultaneously, or that at least two, and especially all, detection processes intersect at least partially in time. The method according to the invention produces the same advantages as already described with respect to the illumination module according to the invention.

[0047] The detection of the reference mark can be configured to be performed by optical and / or tactile measurements of at least one optical unit. Alternatively, according to the invention, at least one optical unit can be laser-processed in step g) of the method according to the invention. The laser processing can particularly involve removing an opaque coating on the light-incident side of the optical unit in a locally defined area, thereby creating a light-incident opening on the optical unit.

[0057] Figure 1 A schematic front view of the illumination module 1 according to the invention is shown. The viewing direction is opposite to the main emission direction H of the illumination module and points towards the light emitting side 3.4 of the optical unit 3. The illumination module has a first optical unit 3 and a second optical unit 3, wherein both the first and second optical units 3 have three lens elements 3.2 respectively. The two optical units 3 are fixedly mounted on a support element 4. Here, the support element 4 is implemented as a frame, particularly a surrounding frame. The lens elements 3.2 are implemented with at least partial rotational symmetry. The lens elements 3.2 of the first optical unit 3 and the second optical unit 3 are identical and implemented as non-spherical collimator lens elements. The lens elements 3.2 are partially material-locked together and form an integral component.

[0058] Figure 2 A schematic side view of the illumination module 1 according to the invention is shown. The viewing direction is orthogonal to the main emission direction H of the illumination module 1. The optical unit 3 has a light incident side 3.3 and a light emitting side 3.4, wherein the light incident side 3.3 is positioned in front of the light emitting side 3.4 with respect to the main emission direction H of the illumination module 1. The lens element 3.2 has at least a partially convex surface on the light emitting side 3.4, wherein the focal point F of the convex surface is located in the lens element 3.2. A light source unit 2 is provided on the light incident side 3.3 of the optical unit 3, the light source unit having a light source 2.1, a circuit board 2.2, and a cooling body 2.3. The cooling body 2.3 is provided on the side of the circuit board 2.2 facing away from the lens element 3.2 and has a plurality of (not shown) cooling ribs for efficient heat dissipation. The light source 2.1 is configured as an LED and is provided on the side of the circuit board 2.2 facing the lens element 3.2.

[0059] The lens elements 3.2 of the optical unit 3 each have at least partially convex surfaces on the light-emitting side 3.4, wherein the focal point F of the respective convex surface is located in the respective lens element 3.2. Here, the lens element 3.2 is implemented as a rotationally symmetric collimator lens element. The lens elements 3.2 are implemented with a planar orientation toward the light source unit 2, thereby creating a planar light-incident surface 3.3 of the optical unit 3.

[0060] Figure 3A schematic rear view of the illumination module 1 according to the invention is shown. The viewing direction is along the main emission direction H of the illumination module and points to the light incident side 3.3 of the optical unit 3. The light emitting side 3.4 of the optical unit 3 is provided with an opaque coating 3.5, wherein a plurality of light incident openings 3.6 are respectively provided in the opaque coating 3.5. In other words, a plurality of gaps are provided in the opaque coating 3.5, through which light can enter the optical unit 3. A reference mark 3.1 is provided on the light incident side 3.3 of each of the two optical units 3, wherein the reference mark 3.1 is implemented identically on both optical units 3. A light source 2.1 is provided on each of the light incident openings 3.6, wherein the light source 2.1 is shown by dashed lines for clarity. The dashed lines correspond to the surface of the light source 2.1 projected along the main emission direction. The surface of the projection of the light source 2.1 at least partially overlaps with the corresponding light incident opening 3.6. Here, at least one edge of the corresponding light emission opening is positioned outside the projection plane of the corresponding light source 2.1. The light incident side 3.3 of the optical unit 3 is planarly implemented and disposed in a common plane orthogonal to the main emission direction H.

[0061] Figure 4 The diagram schematically illustrates the relative positional movement between two reference markers in a Cartesian coordinate system with Cartesian coordinate directions X, Y, and Z. Each reference marker 3.1 is disposed on a separate optical unit, which is not shown for clarity. The light incident side 3.3 of the optical unit 3 (not shown) is planarly implemented and disposed in the XY plane. The reference markers 3.1 are disposed on the corresponding light incident side 3.3 of the optical unit 3 and are therefore also in the same plane. The relative positional movement between the first and second positional movements can be determined by detecting the orientation and rotation of the two reference markers in the common plane. The relative positional movement currently has a misalignment DX of translation along the X direction, a misalignment DY of translation along the Y direction, and a misalignment DR of rotation between the reference markers (which may be given, for example, in angles). The rotation of the reference markers 3.1 currently involves rotation about a rotation axis oriented perpendicular to the XY plane (along the Z direction). The determined relative positional movement between at least two reference markers 3.1 can now be compensated for with a theoretical value of the positional movement. Based on the deviation between the actual position movement and the theoretical position movement, at least one processing position on at least one optical unit can then be determined. Thus, for example, a light incident opening can be positioned on at least one optical unit 3 depending on the relative position movement between at least two optical units 3, such that the combined action of all optical units 3 creates the desired light pattern.

[0062] Figure 5A schematic side view of an embodiment of the illumination module 1 according to the present invention is shown. The viewing direction is orthogonal to the main emission direction H of the illumination module 1. The illumination module additionally includes a projection module 5, wherein the projection module has a first lens element 5.1 and a second lens element 5.1. Here, the lens element 5.1 positioned closer to the optical unit 3 with respect to the main emission direction H has a positive focal length, and the lens element 5.1 positioned farther from the optical unit 3 with respect to the main emission direction H has a negative focal length. The two lens elements 5.1 are arranged opposite each other and positioned such that the focal point F of the first lens element 5.1 coincides with the focal point F of the second lens element 5.1.
