  • the layer structure of the cover cap comprises a plastic support layer, a light guide layer arranged directly on the same and designed to guide light, in particular light in the spectrum visible to the human eye, and a multi-layer decorative layer arranged directly on the light guide layer, which is at least partially translucent and which can also be used as Decorative layer can be referred to and can be realized by a decoration, a pattern or the like.
  • the cover cap is designed to be removable, in such a way that it can be removed from the recess without causing any damage.
  • the vehicle component has a layer structure with various layers and a light source for providing light, in particular light in the spectrum visible to the human eye.

  • the cover cap decorative lighting device thus provides a cover cap that can be inserted into a recess in a vehicle component and then removed again, with a multi-layer decorative layer that is implemented by means of a decoration, a pattern or the like to increase the value of the vehicle and is designed to be backlit or translucent to further enhance the vehicle and to increase the comfort of a user of the vehicle.
  • Electrical components for providing and, if necessary, controlling the light used to backlight or translucent the multi-layer decorative layer are installed in the vehicle component and not in the cover cap, which makes the cover cap relatively compact and lightweight.
  • the multilayer decorative layer has individual layers.
  • a first individual layer of these individual layers can be opaque to the light provided by the light source. Further individual layers of these individual layers can be transparent and/or translucent to the light provided by the light source.
  • the multilayer decorative layer can be freely designed using the individual layers. Decoration, patterns or the like can thus be provided relatively easily and in a wide variety.
  • the individual layer with opaque properties is completely impermeable to light and is realized, for example, by masking.
  • An individual layer of the further individual layer with transparent properties is completely permeable to light.
  • An individual layer of the further individual layer with translucent properties is for Designed to allow light to pass through in part, whereby the corresponding individual layers can be made from coloured layered material, for example.
  • the said cover cap has at least one reflector embedded in the light guide layer and/or the multi-layer decorative layer, which is designed to reflect the light provided by the light source.
  • the at least one reflector With the help of the at least one reflector, light provided by the light source and coupled into the light guide layer can be reflected in a targeted manner, for example in such a way that selected sections of the multi-layer decorative layer are illuminated and/or a predetermined light path can be realized.
  • the cover cap can have a frame arranged on the light guide layer and/or the multi-layer decorative layer, which encloses the light guide layer and/or the multi-layer decorative layer and/or the plastic support layer at least in sections.
  • the frame can expediently form a type of border that runs around the layer structure of the cover cap and, if necessary, simplifies the assembly of the cover cap in the recess.
  • the said recess in the vehicle component is positioned on the vehicle component in such a way that the cover cap inserted into the recess in the assembled state of the cover cap decorative lighting device is completely enclosed by the vehicle component.
  • This can be achieved, for example, by the recess being formed in the vehicle component at a sufficient distance from an edge of the vehicle component.
  • the said recess in the vehicle component is formed on an edge of the vehicle component in the vehicle component.
  • the invention relates to a cover cap decorative lighting device which has a vehicle component with a recess and a cover cap which has a layer structure which has a plastic support layer, a light guide layer arranged on the same and a multi-layer decorative layer arranged directly on the light guide layer and which can be illuminated at least partially.
  • the cover cap is inserted into the recess with the multi-layer decorative layer pointing away from the recess.

  • the plastic support layer 6 has a first plastic layer 6a and a second plastic layer 6b arranged flat on the first plastic layer 6a.
  • the plastic layers 6a, 6b in particular provide a special load-bearing capacity for the plastic support layer 6, as a result of which the cover cap 4 is, for example, relatively stiff and robust.
  • the said multi-layer decorative layer 8 of the cover cap 4 has multiple individual layers 12, 13, 14, 15.
  • the first individual layer 12 is designed to be opaque to light, so that it is completely impermeable to light and provides a type of masking for generating patterns or the like.
  • the other individual layers 13, 14, 15 are designed to be transparent or translucent to light. The latter can be achieved, for example, by producing them from a colored layer material.

With the help of the reflector 16, light coupled into the light guide layer 7 can be reflected in such a way that predetermined sections of the multi-layer decorative layer 8 are illuminated and other sections of the multi-layer decorative layer 8 can be illuminated to a lesser extent.
  • the cover cap 4 also has a frame 17, which is arranged from the outside on the light guide layer 7 and on the multi-layer decorative layer 8, and realizes a type of enclosure by means of which the light guide layer 7 and the multi-layer decorative layer 8 are framed.
