Polymeric vehicle window having an LED assembly

1. A polymeric vehicle window pane, comprising:

a composite component having an inner opaque polymeric layer and an outer transparent polymeric layer,

wherein the inner opaque polymeric layer and the outer transparent polymeric layer are areally bonded,

wherein the inner opaque polymeric layer has at least one at least partially penetrating recess, and an LED assembly, having one LED, one printed circuit board, and electrical contacting, is arranged in the recess, and

wherein the LED assembly is placed such that the LED is aimed in the direction of the outer transparent polymeric layer.

2. The vehicle window pane according to claim 1 , which is a side window pane, preferably a stationary rear side window pane, or a rear window pane.

3. The vehicle window pane according to claim 1 , wherein the outer transparent polymeric layer has an elevation or depression in the region of the recess of the inner opaque polymeric layer.

4. The vehicle window pane according to claim 1 , wherein the recess has a cover.

5. The vehicle window pane according claim 1 , wherein the outer transparent polymeric layer has an additional recess in the region of the recess of the opaque polymeric layer.

6. The vehicle window pane according to claim 5 , wherein the recess and/or additional recess has angular preferably circular, slit-shaped and/or rounded reflective surfaces.

7. The vehicle window pane according to claim 1 , wherein the inner opaque polymeric layer and the outer transparent polymeric layer contain polyethylene (PE), polycarbonates (PC), polypropylene (PP), polystyrene, polybutadiene, polynitriles, polyesters, polyurethanes, polymethyl methacrylates, polyacrylates, polyesters, polyamides, polyethylene terephthalate, preferably acrylonitrile-butadiene-styrene (ABS), acrylester-styrene-acrylonitrile (ASA), acrylonitrile-butadiene-styrene-polycarbonate (ABS/PC), polyethylene terephthalate-polycarbonate (PET/PC), and/or copolymers or mixtures thereof.

8. The vehicle window pane according to claim 1 , wherein the outer transparent polymeric layer contains polycarbonates, polymethyl methacrylate, styrene-acrylonitrile, and/or copolymers or mixtures thereof.

9. The vehicle window pane according to claim 1 , wherein the outer transparent polymeric layer includes a hardcoat, preferably heat-curing or UV-curing lacquer, particularly preferably polysiloxanes, polyacrylates, polymethacrylates, and/or mixtures or copolymers thereof.

10. The vehicle window pane according to claim 1 , wherein the inner opaque polymeric layer includes inorganic or organic fillers, preferably SiO 2 , Al 2 O 3 , TiO 2 , clay minerals, silicates, zeolites, glass fibers, carbon fibers, glass beads, organic fibers, and/or mixtures thereof.

11. The vehicle window pane according to claim 1 , wherein the inner opaque polymeric layer has a large window opening, preferably in the range from 20 vol.-% to 80 vol.-%.

12. The vehicle window pane according to claim 1 , wherein the LED assembly is connected to light guides.

13. A method for producing a polymeric vehicle window pane, wherein

a composite component comprising an inner opaque polymeric layer and an outer transparent polymeric layer is obtained in a two-component injection molding process or a two-component injection-compression molding process, wherein the inner opaque polymeric layer has at least one at least partially penetrating recess,

an LED assembly is arranged in the recess and contacted, and

the recess is closed with a cover.

14. The method according to claim 13 , wherein the outer transparent polymeric layer is provided with a hardcoat.

15. Use of a polymeric vehicle window pane according to claim 1 as a side window pane, preferably a stationary rear side window pane, or a rear window pane of a motor vehicle, preferably a car, truck, or bus.
