    [0026] FIG. 1B shows a schematic illustration of the motor vehicle component from FIG. 1A in a further view.

    [0027] FIG. 2A shows a schematic illustration of a motor vehicle component with a lighting function in accordance with a second exemplary embodiment.

    [0028] FIG. 2B shows a schematic illustration of the motor vehicle component from FIG. 2A in a further view.

    DETAILED DESCRIPTION OF THE DRAWINGS

    [0029] In the exemplary embodiments and figures, identical or identically acting constituent parts may be provided with the same reference signs in each case. The elements illustrated and their size relationships among one another should not be regarded as true to scale, in principle. Rather, individual elements may be illustrated with exaggerated thickness or size dimensions in order to enable better illustration and/or in order to afford a better understanding.

    [0030] FIG. 1A shows a motor vehicle component 100 with a lighting function comprising a laminate component comprising a first fiber composite material 1, a second fiber composite material 2, and a further second fiber composite material 2, wherein the first fiber composite material 1 is electrically insulating and the second fiber composite material 2 and the further second fiber composite material 2 are electrically conductive. The first fiber composite material 1 is arranged between the second fiber composite material 2 and the further second fiber composite material 2.

    [0031] Furthermore, the laminate component comprises a plurality of light sources, only one light source 3 of which is illustrated, which is embedded in the first fiber composite material 1. The light source 3 is embodied as an LED and is electrically conductively connected to the second fiber composite material 2. The second fiber composite material has a light exit region 4, from which light emitted by the light source 3 can exit directly so that it is perceptible from outside the motor vehicle component 100. Overall at least one light exit region in each case can be provided per light source.

    [0032] Furthermore, the motor vehicle component 100 comprises a contact 5 and a further contact 5, which electrically conductively connect the light source 3 to the second fiber composite material 2 and the further second fiber composite material 2, respectively.

    [0033] On the surfaces respectively facing away from the first fiber composite material 1, the second fiber composite 2 material and the further second fiber composite material 2 each comprise a transparent, electrically insulating layer 6, which electrically insulating the motor vehicle component 100 toward the outside.

    [0034] FIG. 1B illustrates the motor vehicle component 100 from FIG. 1A in a further view, in which a plan view of the second fiber composite material 2 or of the transparent, electrically insulating layer 6 is shown. The light 8 emitted by the light sources 3 directly from the light exit regions 4, which light generates direct lighting, is able to be discerned well here.

    [0035] FIG. 2A shows a schematic illustration of a motor vehicle component 100 with lighting function in accordance with a second exemplary embodiment. In contrast to the example illustrated in FIG. 1A, a reflection layer 7 is arranged between the first fiber composite material 1 and the further second fiber composite material 2 and is configured to reflect light emitted by the light source 3 in such a way that the reflected light can exit from the light exit region 4. The reflection layer 7 provides indirect coupling out of light.

    [0036] FIG. 2B illustrates the motor vehicle component 100 from FIG. 2A in a further view, in which a plan view of the second fiber composite material 2 or of the transparent, electrically insulating layer 6 is shown. The light 8 emitted by the light sources 3 from the light exit regions 4 indirectly via the reflection layer 7 provides indirect lighting that is more diffuse in comparison with the exemplary embodiment in accordance with FIG. 1A.

    [0037] Alternatively or additionally, the exemplary embodiments shown in the figures can have further features in accordance with the embodiments of the general description.
