Abstract

A glass panel assembly is provided intended for use in a roof assembly of a vehicle. It has a layered glass panel comprising a first glass panel with a first glass panel upper face and an opposite first glass panel lower face and a second glass panel with a second glass panel upper face and an opposite second glass panel lower face. The first glass panel and second glass panel by means of a laminating layer are laminated to each other at the first glass panel lower face and the second glass panel upper face. At least one light incoupling assembly is provided on the second glass panel lower face, which light incoupling assembly comprises at least one light source with light incoupling element. The light incoupling element comprises a rectangular prism.

Claims (30)

1 . A glass panel assembly for use in a roof assembly of a vehicle, the glass panel assembly having a layered glass panel comprising:

a first glass panel with a first glass panel upper face and an opposite first glass panel lower face;

a second glass panel with a second glass panel upper face and an opposite second glass panel lower face;

a laminating layer laminated to each other at the first glass panel lower face and the second glass panel upper face; and

at least one light incoupling assembly provided on the second glass panel lower face, which light incoupling assembly comprises at least one light source with light incoupling element and wherein the light incoupling element comprises a rectangular prism.

2 . The glass panel assembly according to claim 1 , wherein the rectangular prism mainly is made of ultra clear glass.

3 . The glass panel assembly according to claim 2 , wherein the rectangular prism is connected to the second glass panel lower face by a layer of an optic adhesive.

4 . The glass panel assembly according to claim 3 , wherein the layer of an optic adhesive is an ultra-thin layer.

5 . The glass panel assembly according to claim 1 , wherein the layered glass panel is a fixed panel and wherein near to a perimeter of the second glass panel lower face a glue bead is provided configured to connect the layered glass panel with, and configured to provide a watertight seal relative to, a part of the vehicle.

6 . The glass panel assembly according to claim 1 , wherein the layered glass panel is a movable panel and wherein a perimeter of the second glass panel lower face is configured to directly or indirectly cooperate with a seal provided on a part of the vehicle.

7 . The glass panel assembly according to claim 1 , wherein the first glass panel and second glass panel, as viewed in a top plan view, are provided with identical or substantially identical outlines.

8 . The glass panel assembly according to claim 1 , wherein the first glass panel and the second glass panel have identical or substantially identical thicknesses.

9 . The glass panel assembly according to claim 8 , wherein the first glass panel and the second glass panel have a thickness of about 2.1 mm.

10 . The glass panel assembly according to claim 1 , wherein light outcoupling provisions are provided in a desired pattern at an interface between the second glass panel upper face and the laminating layer.

11 . A roof assembly of a vehicle, comprising:

a frame part surrounding a roof opening in a roof part of the vehicle; and

a glass panel assembly having a layered glass panel comprising:

a first glass panel with a first glass panel upper face and an opposite first glass panel lower face;

a second glass panel with a second glass panel upper face and an opposite second glass panel lower face;

a laminating layer laminated to each other at the first glass panel lower face and the second glass panel upper face; and

at least one light incoupling assembly provided on the second glass panel lower face, which light incoupling assembly comprises at least one light source with light incoupling element and wherein the light incoupling element comprises a rectangular prism.

12 . The roof assembly according to claim 11 , wherein the rectangular prism mainly is made of ultra clear glass.

13 . The roof assembly according to claim 12 , wherein the rectangular prism is connected to the second glass panel lower face by a layer of an optic adhesive.

14 . The roof assembly according to claim 11 , wherein the layered glass panel is a fixed panel and wherein near to a perimeter of the second glass panel lower face a glue bead is provided configured to connect the layered glass panel with, and configured to provide a watertight seal relative to, a part of the vehicle.

15 . The roof assembly according to claim 14 , wherein the said part of the vehicle is a body-in-white of the vehicle.

16 . The roof assembly according to claim 11 , wherein the layered glass panel is a movable panel and wherein a perimeter of the second glass panel lower face is configured to directly or indirectly cooperate with a seal provided on a part of the vehicle.

17 . The roof assembly according to claim 16 , wherein the said part of the vehicle is a body-in-white of the vehicle.

18 . The roof assembly according to claim 11 , wherein the first glass panel and second glass panel, as viewed in a top plan view, are provided with identical or substantially identical outlines.

19 . The roof assembly according to claim 11 , wherein the first glass panel and the second glass panel have identical or substantially identical thicknesses.

20 . The roof assembly according to claim 19 , wherein the first glass panel and the second glass panel have a thickness of about 2.1 mm.
