[0002] METHOD FOR MANUFACTURING A COMPONENT, IN PARTICULAR A VEHICLE COMPONENT
[0003] The invention relates to a method for manufacturing a component, in particular a vehicle component, which provides for arranging an object made of plastic onto a support body.
[0004] Corresponding methods for manufacturing a component, in particular a vehicle component, are known in principle from the prior art. For example, it is known to attach an object manufactured using an additive manufacturing process to a load-bearing component by means of an adhesive bond in a subsequent step. The use of objects manufactured using additive manufacturing processes as vehicle components is also fundamentally known.
[0005] The invention is based on the objective of providing a method for manufacturing a component, in particular a vehicle component, which makes it possible to produce a component that is easily customizable and meets high quality requirements with reasonable effort and costs.
[0006] The problem is solved by a method for manufacturing a component according to claim 1. The dependent claims relate to possible embodiments of the method. Furthermore, the problem is solved by a component according to claims 11 and 12.
[0007] The invention relates to a method for manufacturing a component, in particular a vehicle component, wherein the method comprises the process step of providing a support component on which at least a planar textile layer is attached. The support component can, for example, have a mechanical interface by means of which the support component can be attached or fastened to a vehicle base structure, e.g., a component of the vehicle body. For example, the support component is equipped with a locking lug and / or a threaded bolt and / or a threaded hole and / or another interface element enabling a force-fit and / or form-fit and / or material-fit connection with a vehicle base structure. Preferably, this at least one interface element is located on a first page 24-1871
[0008] and / or main extension surface of the supporting component and at least a predominant area section of the textile layer on a second side facing away from this first side or on the main extension surface of the supporting component facing away from this first main extension surface.
[0009] In a further process step, an object is created on the surface of the planar textile layer using an additive manufacturing process. This additive manufacturing process is characterized by the fact that a building material, consisting at least partially of plastic, is applied layer by layer to form the object. The building material can be applied to a build layer as a strand and / or as a powder and / or droplets, where it undergoes at least partial or complete solidification.The additive manufacturing process used can be, for example, a fused filament fabrication (FFF) process, and / or a selective laser sintering (SLS, especially powder-based) process, and / or a fused granular fabrication (FGF) process, and / or a stereolithography (SLA) process, and / or a digital light processing (DLP) process, and / or a multi-jet modeling (MJM) process, also known as poly-jet modeling (PJM), and / or, more generally, a material jetting process. In this process, for example, a liquid or paste-like resin is applied layer by layer and cured by means of a thermal energy source, such as a UV lamp and / or an IR emitter. For example, a liquid and / or powdered and / or droplet-shaped build material can be dispensed via an dispensing device or application unit to form a layer of material and then solidified by a solidification unit.The hardening device can, for example, be an energy source emitting thermal energy. Alternatively or additionally, the hardening device can be designed as a radiation device emitting UV radiation, which acts on the applied building material and hardens it. Optionally, the thermal energy can be applied to specific areas of a layer of the building material with UV radiation, depending on the area being treated, to achieve hardening and form the object. For example, a hard wax or a thermoplastic, particularly a wax-like one, is used as the building material. Alternatively or additionally, the building material can consist of a thermoset or thermosets and / or from 24-1871.
[0010] The material consists of or at least partially comprises elastomers. Alternatively or additionally, a UV-sensitive photopolymer can be used as the building material, so that this material experiences an increase in strength through exposure to UV radiation. Optionally, the pre-hardened building material can undergo further hardening or a further increase in strength in a post-hardening step, e.g., by applying thermal energy. For example, a photopolymerizable resin is used as the building material in the additive manufacturing process. The thermal energy source used to harden the building material can be configured, for example, to apply thermal energy to the material at specific points or over a large area. For example, localized thermal energy application can be achieved by means of a thermal energy source emitting at least one laser beam.
[0011] By building the object onto the textile layer already bonded to the support structure, the advantage is achieved that a defined position and / or orientation of the object relative to the support structure and textile layer can be easily established. In contrast, printing the object onto the textile layer and subsequently stretching the printed textile layer onto the support structure would have the disadvantage of increasing the risk of cracking and / or deviations in the object's actual position and / or orientation relative to the support structure during the stretching process. Finally, the object or the building material would be subjected to tension during the stretching of the printed textile layer onto the support structure, which could lead to distortion of the printed geometry.
[0012] The method described herein allows an object to be additively built up on a curved surface of the textile layer. For this purpose, the supporting body can, for example, have a curved surface, in particular a surface that is at least partially convex or concave, onto which the building material is applied during the additive manufacturing process.
[0013] In a preferred embodiment, a pretreatment of the textile layer and / or the support body can be carried out before and / or during the creation of the object on the surface of the textile layer, which leads to an influence of 24-1871
[0014] This leads to adhesive properties that bond the building material to the textile layer or to the supporting structure. For example, during pretreatment, a pretreatment medium (e.g., a pretreatment liquid) is applied to the textile layer or the supporting structure and / or the textile layer or the supporting structure is subjected to mechanical stress. This allows for manipulation of a location on the surface of the textile layer before or during the additive manufacturing of the object. For example, mechanical contact, such as rubbing and / or grinding, and / or the application of a substance, e.g., in liquid form, can be applied to achieve an adhesion-enhancing or adhesion-reducing effect on the surface of the textile layer, particularly depending on the area. This allows for targeted control of the degree of adhesion of the building material forming the object to the textile layer.Optionally, pretreatment can be carried out by vaporizing the textile layer and / or the support body and / or by passing over the textile layer and / or the support body with a thermal energy source, e.g. a UV lamp.
[0015] The object built on top of the textile layer can, for example, fulfill an anti-slip function during the intended use of the component, thus preventing accidental slippage. The object built on top of the textile layer can, for example, have a height above the textile layer of at least 1.0 mm, preferably at least 2.0 mm, particularly preferably at least 4.0 mm, and more preferably at least 10.0 mm, and / or a maximum height of 20 mm, preferably a maximum of 10 mm, particularly preferably a maximum of 5.0 mm, and more preferably a maximum of 3.0 mm.
[0016] It is possible that the constructed object is made of a colored and / or transparent building material. In the case of a transparent building material, this can be used as a light guiding and / or light modifier. Thus, an object constructed of a transparent building material can, in its intended operation, be illuminated by a light source, and the light emitted by the light source can be guided and / or modified, at least partially, through the object. For example, the object functions as an optical lens and / or an optical light guide. It is possible that a light source is arranged or formed on, in particular in or on, the supporting body, the emitted light of which
[0017] Light is directed onto the object. This allows a lighting effect of the component to be created.
[0018] For example, the textile layer may have a surface impregnation which is altered, particularly weakened, at least in certain areas through manipulation, so that a normally poorer degree of bonding between the textile layer and the object can be prevented in these areas, or a better bond can be achieved in these areas. A liquid, such as a mild acid, can be used to achieve a pretreatment of the textile layer, particularly one that is area-dependent. Alternatively or additionally, an oxidizing agent, such as one containing at least some ozone, can be used. Alternatively or additionally, pretreatment or preparation of the textile layer can be achieved by treating it, at least in sections, mechanically and / or chemically (e.g., etching) and / or with UV light.
[0019] A photopolymer used as a building material for additive manufacturing is a polymer that changes its properties when irradiated with light from the UV or UV-VIS range of the electromagnetic spectrum. This can result in a structural change in the building material, such as photochemical curing through cross-linking. For example, the building material can be composed of a mixture of monomers, oligomers, and photoinitiators that transform into a cured material during photopolymerization.
[0020] It is possible that a sheet-like textile layer is used, which is formed at least partially, preferably predominantly, particularly preferably entirely, from or consists of a textile raw material, in particular natural fiber and / or synthetic fiber, and / or at least partially from a non-textile raw material, in particular leather and / or artificial leather and / or nonwoven fabric and / or feathers. The sheet-like textile layer can, for example, be formed at least partially, preferably predominantly, particularly preferably entirely, as a metal mesh. 24-1871
[0021] The textile layer can be attached to the supporting structure by means of force, fabric connection, and / or form-fitting. For example, the textile layer is attached to the supporting structure by means of adhesive bonding and / or by means of at least one fastening device, e.g., a clamp or rivet, and / or by clamping.
[0022] The sheet-like textile layer can, for example, be formed at least partially, preferably predominantly, and particularly preferably entirely, from a woven and / or knitted and / or braided and / or stitched and / or nonwoven fabric and / or felt. Thus, the textile layer can, for example, consist of at least two yarn systems, comprising warp and weft, which intersect in a pattern at an angle, particularly of exactly or approximately 90°, when viewed from the fabric surface. Preferably, the warp system and / or the weft system can be composed of one or more types of warp or weft (e.g., ground, pile, and filler warp; ground, binding, and filler weft). The sheet-like textile layer can, for example, have a number of stitches per 100 mm (stitches and / or rows of stitches) in the range of 40 to 80, preferably 50 to 70.In a preferred embodiment, the planar textile layer can have mesh rods (n / 100 mm) in the range of 40 to 85, preferably 50 to 75, particularly preferably 60 to 65, alternatively or additionally, the planar textile layer can have rows of meshes (n / 100 mm) in the range of 60 to 180, preferably 90 to 150, particularly preferably 110 to 130.
[0023] The sheet-like textile layer may, for example, have been produced using a flat knitting process. Alternatively or additionally, the sheet-like textile layer may have a basis weight of 600 g / m². 2 up to 1000 g / m² 2 , preferably 700 g / m² 2 up to 900 g / m² 2 , exhibit. The sheet-like textile layer can, for example, have a thickness (especially at a measuring pressure of 0.02 N / cm²). 2 ) of 1.0 mm to 5.0 mm, preferably of 1.5 mm to 4.5 mm, particularly preferably of 2.0 mm to 3.5 mm, most preferably of 2.2 mm to 3.0 mm.
[0024] The building material can, for example, be introduced at least sectionally into at least one recess of the planar textile layer during the object's production. For example, at least one recess of the textile layer is predominantly, and in particular completely, filled by the building material. The recess of the textile layer can, for example, be formed by a 24-1871
[0025] The at least one opening may have been created in the textile layer by a separating process. For this purpose, the opening may have been created in the textile layer, for example, by means of a mechanical and / or thermal and / or electrical and / or chemical separating process, in particular by punching, shearing, drilling, punching, burning, laser, electron beam, or etching. The opening may be, for example, a blind hole, i.e., without a recess completely penetrating the thickness of the textile layer, or a through hole, i.e., a recess completely penetrating the thickness of the textile layer.
[0026] It is possible that, during the object's production, the building material penetrates at least one recess in the planar textile layer, at least in certain sections, and comes into contact with the supporting structure and / or with at least one intermediate body arranged between the textile layer and the supporting structure. For example, the building material penetrating the textile layer forms a material-bonded connection with the supporting structure and / or with the intermediate body arranged between the textile layer and the supporting structure. In other words, the object built up on the textile layer in an additive manufacturing process can, at least in certain sections, directly form a force-fit, material-bonded, and / or form-fit connection with the supporting structure and / or with an intermediate body arranged between the textile layer and the supporting structure.To improve the connection of the object to the supporting body and / or the intermediate body, the supporting body and / or the intermediate body may be provided with an adhesion-enhancing measure, at least in sections, preferably on the surface areas where contact with the object is planned. For example, the corresponding surface area of the supporting body and / or the intermediate body has an increased surface roughness and / or has been coated and / or treated with an adhesion-enhancing agent.
[0027] For example, at least one intermediate body, in particular at least one intermediate layer, can be arranged between the supporting body and the textile layer. The intermediate body can, for example, have a higher elasticity than the supporting body. The intermediate body can, for example, be a padding material, i.e., a material used as padding or elastic filling for a [material type 24-1871].
[0028] The intermediate layer serves as a cavity formed by the textile layer and the supporting structure. For example, the intermediate layer is made of an open- or closed-cell elastic foam. This allows the textile layer to form a top layer of a component that includes a cushioning area or padding. The manufactured component can thus incorporate a suspension, insulation, and / or wadding function. Alternatively or additionally, the intermediate layer can include at least a heating and / or cooling element (e.g., a heating wire) and / or at least a light source and / or at least a light-conducting or light-modifying element. The heating element, for example, can be used to temperature-control a contact point between the component and a vehicle occupant in the case of a component installed on a steering wheel or vehicle seat.
[0029] For example, during the build-up process on the textile layer, the first layer of material, facing the textile layer, may have a lower viscosity (more fluid) than a subsequent layer applied on the opposite side of the first layer, particularly on top of the first layer. This allows, for instance, a layer of the building material applied directly onto the textile layer to be more fluid or have a lower viscosity than a layer applied later and / or at a location further away from the textile layer. Due to the lower viscosity of the first applied layer, the building material can more easily penetrate and fill gaps or recesses in the textile layer.The subsequent material layer applied to a first material layer or group of material layers can exhibit a higher viscosity or even a very high viscosity compared to the first material layer or group of material layers. This means that any indentations or gaps that form in the material layers due to the recesses or spaces of the textile layer become increasingly less pronounced or disappear altogether as the layers are applied. For example, the different viscosities can be achieved through targeted temperature control of the material. A higher processing temperature can be maintained in the first layers to achieve a lower viscosity. [24-1871.]
[0030] The viscosity can be increased. Alternatively or additionally, a multi-material printhead can be used to apply or dispense build materials with different viscosities. For example, a first nozzle can dispense a build material with a lower viscosity, and a second nozzle can dispense a build material with a higher viscosity for the printing process of the object, particularly within a single build job.
[0031] The component produced by the method described herein can, for example, form a vehicle interior component. For example, the component forms a trim part, preferably a pillar trim part, and / or a vehicle door part, and / or a dashboard part, and / or a steering wheel part, and / or a vehicle seat part, and / or an armrest part, and / or a sun visor part, and / or a vehicle key part, and / or an exterior component.
[0032] It is possible that the object built upon the textile layer forms an information carrier, at least in sections. For example, the information carrier can form at least a pictogram and / or an alphanumeric character, at least in sections. Thus, it is possible to use the textile layer as at least a partial covering or textile covering for a steering wheel, where the object built upon this textile layer forms a symbol, e.g., a horn symbol with the contour shape of a horn.
[0033] In addition to the method for manufacturing a component, the invention also relates to a component, in particular a vehicle component, comprising a load-bearing component on which at least a planar textile layer is attached. The component is formed from at least one load-bearing component, at least one textile layer, and an object. The object is built up layer by layer on the surface of the textile layer using an additive manufacturing process with a build material that at least contains plastic.
[0034] Optionally, the object can be made at least partially, preferably predominantly, and particularly preferably completely, of a transparent material. This at least partially transparent object can preferably be used to guide or allow light to pass through. For example, see an,24-1871
[0035] This includes, for example, a light source arranged, formed, or arrangable in or on the supporting structure. The light source can be positioned and / or aligned with the object in such a way that a light beam emitted by the light source passes through the object. For example, the object can function as an optical lens and / or a light guide, such that a light beam, particularly one emitted by the light source, undergoes a predefined modification and / or guidance / direction as it passes through the object. A modification of the light beam can, for example, include beam expansion and / or beam narrowing and / or a change in color. Thus, for example, a light beam striking the object as a white light beam can be modified by the object to achieve a defined color effect, in particular by filtering.
[0036] The support body can be made of plastic, preferably a thermoplastic or thermosetting plastic. For example, the support body can be made of ABS plastic (acrylonitrile butadiene styrene copolymer). Alternatively, the support body can be made of plastic, at least in sections.
[0037] All advantages, details, designs and / or features of the method according to the invention are transferable or applicable to the molded body according to the invention.
[0038] The invention is explained in more detail with reference to exemplary embodiments in the drawings. These show:

[0040] Fig. 2 shows a schematic representation of a component comprising a support body, an intermediate body and a planar textile insert according to a second embodiment; 24-1871
[0041] Fig. 3 shows a schematic representation of a component comprising a support body, an intermediate body and a planar textile insert according to a third embodiment;
[0042] Fig. 4 shows a schematic representation of an object designed as a horn symbol on a flat textile insert according to a fourth embodiment;
[0043] Fig. 5 shows a schematic representation of process steps for manufacturing a component according to an exemplary embodiment.
[0044] The figures show a component 1 that was manufactured using a method shown in Figure 5. This component 1 can, for example, be a vehicle component. The method involves providing a support body 2 on which at least a planar textile layer 3 is attached. The planar textile layer 3 can be attached to the support body 2 by means of a force-fit, form-fit, and / or material-fit connection. In a further process step, an object 4 is created on a surface 5 of the textile layer 3 using an additive manufacturing process. The additive manufacturing process used here employs a plastic building material that builds up or shapes the object 4 layer by layer, forming the component 1, which is composed at least of the support body 2 and the object 4.In other words, the object 4 produced in the additive manufacturing process is built up directly onto the upward-facing or exposed surface of the textile layer 3 in a layer-by-layer process. For this purpose, the building material can be applied directly to the surface 5 of the textile layer 3 by an application unit (not shown) of an additive manufacturing device and cured there actively (e.g., due to UV radiation) or passively (e.g., due to room temperature). It is also possible to insert at least one support body 2 provided with the textile layer 3 into a manufacturing device and to carry out the additive build-up of the at least one object 4 there. It is therefore possible for several support bodies 2 to be inserted into an additive manufacturing device simultaneously and for several objects 4 to be built up in one build job, preferably on the support bodies 2 assigned to the respective objects 4. 24-1871.
[0045] For example, a planar textile layer 3 can be a textile layer 3 formed at least partially, preferably predominantly, and particularly preferably completely, from a textile raw material, in particular natural fiber and / or synthetic fiber, and / or at least partially from a non-textile raw material, in particular leather and / or feathers. A planar textile layer 3 can, for example, be formed at least partially, preferably predominantly, and particularly preferably completely, from a woven and / or knitted and / or braided and / or stitched and / or nonwoven and / or felt.
[0046] The building material can, for example, be introduced at least partially into at least one recess 6 of the planar textile layer 3 during the production of object 4. For example, at least one recess 6 of the textile layer 3 is predominantly, and in particular completely, filled by the building material, see Figure 3. The recess 6 of the textile layer 3 can be designed as a blind hole and / or as a through hole. As can be seen, for example, in Figure 4, the at least one recess 6 can be formed by a space or spaces between intersecting thread elements 12, 12' of the textile layer 3. In the case of a through hole, the building material forming object 4 can come into contact with the supporting body 2, at least partially, see Figure 3.Figure 3 schematically shows cross-sectional views of thread elements 12, 12' running perpendicular to the plane of the drawing, illustrating that the building material comes into contact with the supporting body 2 via the spaces between the thread elements 12, 12' or extends through these spaces. Optionally, a force-fit, material-fit, and / or form-fit connection between the object 4 and the supporting body 2 can be established, at least partially.
[0047] As shown in Figure 2, at least one intermediate body 8, in particular an intermediate body 8 designed as a planar intermediate layer, can be arranged between the planar textile layer 3 and the support body 2. For example, an intermediate body 8 can first be arranged on a surface of the support body 2, and the textile layer 3 can then be placed on this intermediate body 8, or the textile layer 3 can cover the intermediate body 8. The intermediate body 8 can, for example, be made of foam or of a 24-1871
[0048] The textile layer 3 may be made of padding material or an elastic material, or may exhibit elastic properties. Optionally, the textile layer 3 can shield and / or cover the intermediate body 8 at least partially, preferably predominantly, and particularly preferably completely. In other words, the textile layer 3 and the support body 2 can form an externally closed cavity in which the at least one intermediate body 8 is arranged. Optionally, the at least one intermediate body 8 can be arranged on a surface of the textile layer 3, in particular glued or stapled, and arranged as an assembly, i.e., the textile layer 3 with the intermediate body 8, on the support body 2 and fixed there. For example, the fixing of the textile layer 3 and the intermediate body 8 to each other and / or to the support body 2 can be achieved at least partially by means of the additively constructed object or the building material applied for this purpose.
[0049] For example, during the production of object 4, the building material can, at least partially, penetrate at least one recess 6 of the planar textile layer 3 and come into contact 7 with the support body 2 and / or with at least one intermediate body 8 arranged between the textile layer 3 and the support body 2. Optionally, the building material penetrating the textile layer 3 can form a material-bonded connection with the support body 2 and / or with the intermediate body 8 arranged between the textile layer 3 and the support body 2. Alternatively or additionally, a force-fit and / or form-fit connection can result between object 4 and the support body 2 and / or between object 4 and the intermediate body 8.
[0050] The textile layer 3 can, for example, be attached to the supporting body 2 as a covering, i.e. by creating a pretension in the textile layer 3.
[0051] Preferably, the assembly of object 4 onto the support body 2 can take place while the support body 2 is attached to a higher-level assembly structure. For example, the support body 2 can be attached to a vehicle base structure as a vehicle component, and in this attached state, an additive manufacturing device can assemble object 4 onto the surface 5 of the textile layer 3. 24-1871
[0052] In an optional process step, at least one intermediate body 8 can be arranged. The intermediate body 8 can be designed as at least one intermediate layer which, in the applied or arranged state, has a direction essentially parallel to the textile layer. It is possible that the intermediate body 8 has a higher elasticity and / or flexibility than the support body 2. The intermediate body 8 can, for example, be a cushioning material, i.e., a material used as padding or elastic filling for a cavity formed by the textile layer 3 and the support body 2. For example, the intermediate body 8 is made of an open- or closed-cell elastic foam.
[0053] For example, the build material can have a lower viscosity during build-up on the textile layer 3 in a first material layer 9 facing the textile layer 3 than in a subsequent material layer 10 built up on a side of the first material layer 9 facing away from the textile layer 3, or during build-up on a previous material layer, particularly on the first material layer 9. In other words, a build material applied close to the textile layer can have a lower viscosity than a build material applied farther away from the textile layer. Thus, the additive manufacturing device can be configured to use different operating parameters during the build-up of an object 4.Thus, the traverse speed and / or the temperature of the applied building material or the building material to be applied can vary, at least depending on the number of layers and / or on whether the building material forms a material layer of object 4 close to or farther from the textile layer. Basically, object 4 is built up by successively applying layers of material 9, 10 to the surface 5 of the textile layer 3, so that first an initial material layer, e.g., the first material layer 9, is applied directly to the surface 5 of the textile layer 3. Then, another material layer, e.g., another material layer 10, is built up directly onto the side of the initial material layer facing away from the textile layer. Then, a subsequent material layer is built up onto the surface of the subsequent material layer facing away from the textile layer. This can be continued indefinitely until a target height of object 4 is reached. 24-1871.
[0054] Optionally, a pretreatment 103 of the textile layer 3 can be carried out before and / or during the production 101 of the object 4 on the surface 5 of the textile layer 3, which influences the adhesive properties for bonding the building material and the textile layer 3. For example, during the pretreatment 103, a pretreatment medium is applied to the textile layer 3 and / or the textile layer 3 is mechanically subjected. The pretreatment 103 can be carried out before, during, or after the placement 102 of an intermediate body 8 on the textile layer 3 and / or on the support body 2.
[0055] Figures 1 to 3 illustrate that, in the additive manufacturing process, the building material for forming the object 4 can be applied to both a flat surface section of the textile layer 3 and a curved surface section 13 of the textile layer 3. For example, the building material can be applied to a concave or convex curved section of the curved surface section 13. Preferably, the application of several material layers 9, 10 can level or flatten the building plane for the applied building material. The curved surface section 13 of the textile layer 3 can be achieved, for example, by supporting or fastening the, in particular flexible, textile layer 3 to a, preferably correspondingly, curved surface section of the supporting body 2.
[0056] Preferably, a vehicle interior component is manufactured as component 1. Such a component can, for example, be a trim part, preferably a pillar trim part and / or a door trim part, and / or a dashboard part and / or a steering wheel part and / or a vehicle seat part and / or an armrest part and / or a sun visor part and / or a vehicle key part and / or an exterior component.
[0057] The object 4, built on the textile layer 3, can, for example, form an information carrier 11, at least in part. The information carrier 11 can, for example, be at least in part a pictogram and / or an alphanumeric character. In the third embodiment shown in Figure 4, the object 4 can form the symbol of a horn. For example, the object 4 designed as a horn symbol can be built on a textile layer 3 of a support body 2 and form a component 1 of a steering wheel.In addition to the method, the invention relates to a component 1, in particular a vehicle component, comprising a support body 2 on which at least partially a planar textile layer 3 is attached, wherein the component 1 consists of the support body 2 and the textile layer 3 and an object 4, wherein the object 4 was built up layer by layer on a surface 5 of the textile layer 3 in an additive manufacturing process by means of which a building material comprising at least plastic was applied to the surface 5 of the textile layer 3.
[0058] Figure 1 illustrates by way of example that the object 4 can be made of a transparent material, at least partially, preferably predominantly, and particularly preferably completely. For example, a light source 14, e.g., an LED device, is arranged or formed, or can be arranged, on, i.e., in or on, the support body 2. The light source 14 can be arranged and / or oriented relative to the object 4 such that a light beam 15 emitted by the light source 14 passes through or penetrates the object 4. For example, the object 4 can function as an optical lens and / or a light guide, such that a light beam 15, particularly one emitted by the light source 14, undergoes a predefined modification and / or guidance / direction as it passes through the object 4.According to the embodiment shown in Figure 1, the light beam 15 emerging from the lighting device 14, which is designed in particular as an LED, can be widened by passing through the object 4. For this purpose, the object 4 can, for example, be constructed at least partially like a diverging lens and / or have a convex surface at least partially. Optionally, the object 4 can be constructed at least partially like a focusing lens and / or have a concave surface at least partially.
[0059] As can be seen from a comparison of Figures 1 and 2, the constructed object 4 can have any surface geometry (raised areas and / or recesses and / or shapes) along all spatial directions. Reference symbol list
