Abstract

A glass assembly includes a first glass layer including a first surface facing an exterior of a vehicle and a second surface opposite to the first surface; a second glass layer including a third surface and a fourth surface opposite to the third surface, the fourth surface facing an interior of the vehicle, and a light-adjusting layer between the first glass layer and the second glass layer, wherein the glass assembly further includes a light-emitting structure on the third surface or the fourth surface of the second glass layer, and wherein the second glass layer is used for reflecting incident light emitted by a light source and emitting the light into the interior of the vehicle through the light-emitting structure.

Claims (19)

1 . A glass assembly comprising:

a first glass layer comprising a first surface facing an exterior of a vehicle and a second surface opposite to the first surface;

a second glass layer comprising a third surface and a fourth surface opposite to the third surface, the fourth surface facing an interior of the vehicle, and

a light-adjusting layer between the first glass layer and the second glass layer,

wherein the glass assembly further comprises a light-emitting structure on the third surface or the fourth surface of the second glass layer,

and wherein the second glass layer is used for reflecting incident light emitted by a light source and emitting the light into the interior of the vehicle through the light-emitting structure.

2 . The glass assembly according to claim 1 , wherein an intermediate layer is arranged between the first glass layer and the second glass layer, and the light-adjusting layer is arranged in the intermediate layer.

3 . The glass assembly according to claim 1 , wherein the light source is adapted to emit the light on the first glass layer and/or the second glass layer from an edge of the first glass layer and/or the second glass layer or vertical to the first glass layer and/or the second glass layer.

4 . The glass assembly according to claim 1 , wherein the light-adjusting layer comprises at least one of a polymer dispersed liquid crystal, a suspended particle device, an electrochromic layer, a thermochromic layer, a photochromic layer or a liquid crystal layer.

5 . The glass assembly according to claim 1 , wherein the light-adjusting layer comprises a coating layer.

6 . The glass assembly according to claim 1 , wherein the light-emitting structure comprises an ink part, a micro-structure, particles and/or a film.

7 . The glass assembly according to claim 6 , wherein the ink part has an L* value greater than 58 in the chromaticity space LAB.

8 . The glass assembly according to claim 6 , wherein the ink part comprises titanium oxide.

9 . The glass assembly according to claim 1 , wherein the first glass layer and/or the second glass layer are provided with a light source hole for receiving at least a part of the light source.

10 . The glass assembly according to claim 9 , wherein the light source hole is formed such that the light source received in the light source hole is arranged in an invisible area of the glass assembly.

11 . The glass assembly according to claim 1 , further comprising an infrared reflection layer between the first glass layer and the light-adjusting layer.

12 . The glass assembly according to claim 1 , further comprising a low radiation layer arranged on the fourth surface of the second glass layer.

13 . The glass assembly according to claim 1 , further comprising a frame structure.

14 . The glass assembly according to claim 1 , further comprising an edge-sealing material arranged at an edge of the light-adjusting layer for sealing the light-adjusting layer.
