Composite pane with illumination
Composite pane, in particular a laminated side pane for a side window of a vehicle. The composite pane includes an outer pane and an inner pane that are bonded to one another via a thermoplastic intermediate layer. The intermediate layer has, at least in some sections, a cutback relative to a pane edge, and at least one light-diffusing optical fiber. The optical fiber is at least partially arranged in the region of the cutback, between the outer pane and the inner pane.
1. A composite pane, being a laminated side pane for a side window of a vehicle, comprising:
an outer pane and an inner pane that are bonded to one another via an intermediate layer, wherein the intermediate layer has, at least in sections, a cutback relative to a side edge; and
at least one light-diffusing glass fiber, wherein the light-diffusing glass fiber is arranged at least partially in a region of the cutback, between the outer pane and the inner pane.
2. The composite pane according to claim 1 , wherein a width of the cutback is from 0.1 μm to 2 mm.
3. The composite pane according to claim 1 , wherein a width of the cutback is from 10% to 400% of a diameter of the glass fiber.
4. The composite pane according to claim 1 , wherein the glass fiber is glued into a region of the cutback by an adhesive means.
5. The composite pane according to claim 4 , wherein the adhesive means contains an adhesive.
6. The composite pane according to claim 1 , wherein the glass fiber is fastened in the region of the cutback by clamping.
7. The composite pane according to claim 1 , wherein the composite pane has at least one heating means for the electrical heating of the composite pane.
8. The composite pane according to claim 7 , wherein the heating means comprises at least one electrically conductive wire and/or at least one electrically heatable, transparent, electrically conductive layer.
9. A composite pane arrangement, comprising:
a composite pane according to claim 1 ; and
a lighting means for coupling light into the glass fiber.
10. The composite pane arrangement according to claim 9 , wherein the lighting means contains at least one laser diode or at least one light-emitting diode.
11. A method for producing a composite pane, comprising:
(a) arranging a thermoplastic intermediate layer between an outer pane and an inner pane;
(b) bonding the outer pane to the inner pane via the intermediate layer by lamination;
(c) cutting back the thermoplastic intermediate layer at least in sections between the outer pane and the inner pane with a cutting tool; and
(d) gluing at least one light-diffusing glass fiber into a region of the cutback with an adhesive means.
12. The method according to claim 11 , wherein the cutting tool is a blade of a knife or a V-shaped blade.
13. A method, comprising:
providing the composite pane according to claim 1 ; and
using the the composite pane in means of transportation for travel on land, in the air, or on water, in trains, watercraft, and motor vehicles, as a windshield, rear window, side window, and/or roof panel.
14. A method for using a lighting means in a composite pane arrangement, comprising:
providing a lighting means; and
using the lighting means in a composite pane arrangement according to claim 9 for the identification of an electrical function.
15. A method for using a lighting means in a composite pane arrangement, comprising:
providing a lighting means; and
using the lighting means in a composite pane arrangement according to claim 9 as a warning function.
16. The composite pane according to claim 1 , wherein a width of the cutback is from 0.1 mm to 1 mm.
17. The composite pane according to claim 1 , wherein a width of the cutback is from 50% to 200% of a diameter of the glass fiber.
18. The composite pane according to claim 1 , wherein a width of the cutback is from 70% to 150% of a diameter of the glass fiber.
19. The composite according to claim 4 , wherein the adhesive means contains an acrylate adhesive, a methyl methylacrylate adhesive, a cyanoacrylate adhesive, a polyepoxide, a silicone adhesive, and/or a silane cross-linking polymeric adhesive, mixtures, and/or copolymers thereof.
20. A method comprising using a lighting means in a composite pane arrangement according to claim 9 for the identification of a heating function and/or a movement of the composite pane.
21. The method according to claim 20 , wherein the composite pane is an opening or closing side window.
22. A method, comprising using the lighting means in the composite pane arrangement according to claim 9 , as a warning function, in an at least partially frameless side pane, in an opened vehicle door.
23. A method, comprising using the composite pane according to claim 1 in buildings, including in the access area, window area, roof area, façade area, or as a built-in component in furniture and appliances.
