Definitions
- the presented invention relates to a light-emitting element for a vehicle, a production method for the light-emitting element and a vehicle with the light-emitting element.
- Luminous elements are of particular importance in a vehicle interior of a vehicle, as their lighting function enables them to both illuminate the interior of the vehicle and to mark functional elements such as buttons or slide controls. Accordingly, luminous elements should be suitable for marking respective functional elements both during the day or when there is strong incidence of light and at night or when there is weak incidence of light.
- lighting elements can have a so-called “day design” in which, for example, strong light is only emitted in response to a user input, and a so-called “night design” in which, for example, weak light is continuously emitted.
- cladding elements are increasingly used in vehicles, which have special optical and / or haptic properties in order to design the vehicle interior.
- cladding elements can also be used to mark functional elements, for example in that a characteristic structure, such as a circuit symbol, is formed in the area of a functional element.
- Such cladding elements are usually made of plastic and are produced, for example, in an injection molding process.
- the cladding elements can be covered with a coating or a seal, such as, for example, a lacquer or a film.
- a cladding element can be produced in a so-called “one-shot process”, ie an injection molding process in which no subsequent coating or sealing takes place, but rather the optical and / or haptic properties of the cladding element during an injection molding process , for example, can be generated by a correspondingly selected injection mold and / or corresponding pressure during the injection molding process.
- WO 2015/124328 A1 describes a method for producing a trim part for an interior of a motor vehicle through which light can shine.
- WO 2018/059862 A1 describes a trim part for a motor vehicle which, in the assembled state, has a visible surface formed by a decorative film that is transparent to light at least in some areas.
- DE 102017209581 A1 describes a cladding element for the interior of a motor vehicle with a decorative layer and at least one fastening means and a light guide for backlighting the decorative layer.
- a lighting element for a vehicle is presented to solve the above-mentioned object.
- the lighting element comprises a one-piece, at least regionally injection-molded cladding element and at least one light element.
- the at least one light element is arranged on an inside of the cladding element and is configured to guide light beams through an outside of the cladding element opposite the inside into an area surrounding the lighting element.
- an injection-molded cladding element is to be understood as an uncoated plastic component, the outside of which, ie a side that is visible in the installed state, is at least partially formed by a corresponding mold during an injection molding process.
- an injection-molded cladding element is what is known as a “one-shot decor”, ie a cladding element that was at least partially produced in a “one-shot process”.
- a spray-finished cladding element therefore remains unpainted or unsealed even in the installed state or in the final state. This means that an injection-molded cladding element does not experience any additional material input after it has been manufactured.
- the at least regionally injection-molded cladding element provided according to the invention is designed in one piece and stands with a Environment in direct contact, since no protective layer, such as a so-called “In-Mold Decoration layer” (IMD) or a so-called “In-Mold Labeling” (IML) is provided.
- the at least regionally injection-molded cladding element provided according to the invention is monochrome, since only a plastic is used to produce the cladding element, the surface of which is designed in such a way that it has the desired properties with regard to light reflection and scratch resistance.
- a light element is to be understood as meaning an element that can be radiated through with light rays from a light source.
- a light element can be a light guide which is connected to a light source or which itself comprises a light source.
- a radiation characteristic is to be understood as a collection of properties of light rays, in particular a radiation geometry and / or a radiation intensity.
- the lighting element presented is based on the combination of an at least regionally injection-molded cladding element and a light element for illuminating, i.e. for backlighting and / or transilluminating the cladding element.
- the combination of the at least partially injection-molded cladding element and the light element allows properties of the cladding element and the light element to be coordinated particularly precisely so that, for example, light beams provided by the light element are precisely coupled into a predetermined area of the cladding element.
- the light beams shine through or backlight the specified area and generate a particularly precise luminous pattern on a surface of the luminous element that is visible from an environment, i.e. a visible surface.
- the properties of the light rays radiating through or backlit by the cladding element are determined directly by the cladding element itself and not by a seal, such as a lacquer or a coating, such as for example a film, definitely.

- a radiation characteristic of the light beams radiating through the recesses can be specified.
- the cladding element has at least one second region, the surface of which has a structure which deflects light beams with a predetermined radiation characteristic that strike the cladding element from an environment.
- the cladding element provided according to the invention can comprise areas that interact with light rays incident from outside, ie from an environment, and deflect them with a predetermined radiation characteristic.
- such areas can, for example, have a structured, in particular grained surface, which deflects the incident light rays and thereby for example appear at least partially matt and / or glossy.
- the cladding element can comprise an area which, when illuminated from an environment, appears matt in relation to a further area of the cladding element and below Illumination by the light element shines particularly strongly in relation to the further area of the cladding element.
- the at least one light element comprises at least one coupling interface for introducing or coupling light beams into at least one counter-coupling interface of the cladding element, the at least one coupling interface having a surface structure that allows light beams radiating through the at least one light element in the direction of the counter-coupling interface distracts.
- a lighting characteristic of the cladding element can be specified very precisely by only coupling light beams selectively into those areas of the cladding element that are supposed to light up according to a specified lighting characteristic or a specified lighting pattern .
- the occurrence of so-called “scattered light”, i.e. lighting up of the cladding element in areas that should not light up according to the specified lighting characteristics, in particular using only one light source, is minimized.
- the presented invention relates to a production method for a luminous element.
- the manufacturing method comprises a generation step for generating an at least regionally injection-molded cladding element in an injection molding process, an arrangement step for arranging at least one light element on the cladding element and an overmolding step for backmolding the at least one light element with plastic in order to attach the at least one light element to the cladding element.
- the production method presented serves in particular to produce the luminous element presented, so that mutual reference can be made or referred to with regard to the advantages of the luminous element and the advantages of the production method.
- the manufacturing method presented is based on a two-stage process, in which initially, in a first step, an at least regionally injection-molded cladding element is produced.
- the cladding element is produced exclusively or completely in one production step, ie in a “one-shot process” and no additional material input for producing the cladding element, such as sealing with a lacquer or a coating takes place through a film.
- the light element provided according to the invention is arranged on the cladding element and finally back-molded with plastic.
- a radiation characteristic of light beams coupled into the cladding element and / or incident on the cladding element can be specified, so that a specified light pattern is created.

- a respective counter-coupling interface can be formed precisely to a respective coupling interface of a corresponding light element, so that the coupling interface and the counter-coupling interface precisely specify a guiding path for light beams provided by the light element, for example by interlocking with one another in a form-fitting manner and minimizing the occurrence of so-called "stray light”.
- the cladding element is produced as a “one-shot decor” in a single production step.
- a “one-shot decoration, which is produced in a single production step, is particularly inexpensive to produce and, due to minimal sources of error, shows a particularly low production tolerance, so that particularly precise luminous patterns can be implemented. It can furthermore be provided that the production method is carried out by means of a single injection molding tool.
- a cladding element By using a single injection molding tool or a single injection mold, a cladding element can be produced and combined directly with a lighting element to form the lighting element presented.

- the luminous element 100 is shown in a detailed representation. It can be seen here that the luminous element 100 comprises first regions 200 in which light beams 201 coupled into the cladding element 101 by the light element 103 are emitted into the environment in a predetermined radiation pattern.
- a first grain 203 on a side of the cladding element 101 facing the light element 103 acts together with a second grain 205 on a side of the cladding element 101 facing the environment, ie facing away from the light element 103, in order to emit the light rays 201 into the environment with the specified radiation characteristics .
- first grain elements 209 of the first grain 203 closest to a negative feedback interface 207 of the cladding element 101 have the effect that scattered radiation from light rays 201 coupled into the cladding element 101 through the light element 103 via its coupling interface 211 is minimized
