Abstract

A glazing assembly includes a light source for generating light which can be coupled into a first pane, an edge region which extends from a pane edge of the first pane over at least 1 mm up to at most 500 mm on one of the surfaces, and to an absorption device for absorbing light which is coupled into the first pane and is arranged in the edge region, wherein the absorption device includes a light-impermeable thermoplastic intermediate layer.

Claims (27)

1. A glazing assembly comprising:

a first pane having a first surface and a second surface, wherein the first pane is provided to at least partially transmit coupled-in light,

a light source for generating light that can be coupled into the first pane,

a light outcoupling means for outcoupling light from the first pane via one of the first and second surfaces,

wherein the first pane is joined to a second pane via an intermediate layer to form a laminated pane,

an edge region which extends from a pane edge of the first pane over at least 1 mm up to at most 500 mm on one of the first and second surfaces, and

an absorption means for absorbing light coupled into the first pane and arranged in the edge region,

wherein the absorption means comprises a light-impermeable thermoplastic intermediate layer.

2. The glazing assembly according to claim 1 , wherein the light-impermeable thermoplastic intermediate layer is colored black.

3. The glazing assembly according to claim 1 , wherein the intermediate layer comprises a transparent thermoplastic intermediate layer and the light-impermeable thermoplastic intermediate layer.

4. The glazing assembly according to claim 3 , wherein the transparent thermoplastic intermediate layer is formed by a first thermoplastic laminated film, and the light-impermeable thermoplastic intermediate layer is formed by a second thermoplastic laminated film, wherein the first thermoplastic laminated film is transparent, and the second thermoplastic laminated film is opaque.

5. The glazing assembly according to claim 4 , wherein the first thermoplastic laminated film extends over the entire surface of the laminated pane with the exception of the edge region, and the second thermoplastic laminated film extends at least; over the edge region of the laminated pane.

6. The glazing assembly according to claim 4 , wherein the opaque thermoplastic intermediate layer extends from the pane edge to a recess in which the light source is arranged.

7. The glazing assembly according to claim 1 , wherein the light-impermeable thermoplastic intermediate layer and the light source do not overlap in the viewing direction through the laminated pane.

8. The glazing assembly according to claim 1 , wherein the absorption means comprises a first cover layer which is arranged on the first surface of the first pane.

9. The glazing assembly according to claim 8 , wherein the second pane has a second cover layer.

10. The glazing assembly according to claim 9 , wherein the first cover layer and/or the second cover layer are/is opaque.

11. The glazing assembly according to claim 8 , wherein the first cover layer extends from a pane edge of the first pane over 1 mm up to 500 mm.

12. The glazing assembly according to claim 1 , wherein the absorption means is arranged at least sectionally along a peripheral pane edge of the laminated pane, or the absorption means extends peripherally along the entire peripheral pane edge.

13. The glazing assembly according to claim 9 , wherein the first cover layer and/or the second cover layer is an opaque enamel.

14. The glazing assembly according to claim 9 , wherein the light-impermeable thermoplastic intermediate layer overlaps the first cover layer and the second cover layer at least partially in the viewing direction through the laminated pane.

15. The glazing assembly according to claim 1 , wherein the laminated pane is a roof pane of a motor vehicle, and the first pane is the inner pane, and the second pane is the outer pane.

16. A vehicle comprising the glazing assembly according to claim 1 .

17. The glazing assembly according to claim 5 , wherein the second thermoplastic laminated film extends exclusively over the edge region of the laminated pane.

18. The glazing assembly according to claim 11 , wherein the first cover layer extends from a pane edge of the first pane over 10 mm up to 150 mm.

19. The glazing assembly according to claim 18 , wherein the first cover layer extends from a pane edge of the first pane over 10 mm to 15 mm.

20. The glazing assembly according to claim 13 , wherein the opaque enamel is applied as a screen print or as a digital print.
