Abstract

A light guide module capable of illuminating and being applied in a device for decoration is provided. The light guide module includes a reflective layer, a light guide with a plurality of diffusing particles, and a light source. The light guide has a side surface, a reflective surface and a light-exiting surface, thereby allowing a light from the light source to enter and reflect and exit the light guide respectively. The reflective layer is disposed on the reflective surface of the light guide for reflecting the light to the light-exiting surface. The light guide forms a portion of an outer surface of the device.

Claims (27)

1. A decoration panel comprising:

a light guide with a plurality of diffusing particles distributed therein, the light guide having a side surface, a reflective surface, and a light-exiting surface, wherein a light enters the light guide through the side surface;

a reflective layer disposed on the reflective surface, for reflecting the light to the light-exiting surface; and

a light shielding pattern layer disposed on the light-exiting surface, wherein the light shielding pattern layer has at least one opening;

wherein the light-exiting surface is uneven and forms a portion of an outer surface of a housing.

2. The decoration panel according to claim 1 , wherein the reflective surface is substantially flat.

3. The decoration panel according to claim 1 , wherein the light guide has at least one protrusion located at the opening of the light shielding pattern layer.

4. The decoration panel according to claim 1 , wherein the light shielding pattern layer is an ink pattern layer and is printed on the light guide.

5. The decoration panel according to claim 1 , further comprising a film layer, wherein the light shielding pattern layer is disposed on the film layer.

6. The decoration panel according to claim 5 , further comprising an adhesion disposed between the light guide and the film layer and located at a periphery of the film layer so that an air gap is formed between the film layer and the light guide.

7. The decoration panel according to claim 1 , wherein the light guide comprises a first portion and a second portion connected to the first portion, wherein a first refractive index of the first portion is greater than a second refractive index of the second portion, and the diffusing particles are distributed within the second portion.

8. The decoration panel according to claim 7 , wherein a thickness of the second portion of the light guide is gradually increased from a first side of the light guide toward a second side opposite to the first side and a distance from the reflective surface to the second portion of the light guide is gradually decreased with the increase of the thickness of the second portion of the light guide, and one of the first side and the second side contains the side surface.

9. A light guide module capable of illuminating and being applied in a device for decoration, the light guide module comprising:

a light source;

a light guide with a plurality of diffusing particles distributed therein, the light guide having a side surface, a reflective surface, and a light-exiting surface, wherein a light provided by the light source enters the light guide through the side surface;

a reflective layer disposed on the reflective surface, for reflecting the light to the light-exiting surface; and

a light shielding pattern layer, disposed on the light-exiting surface, wherein the light shielding pattern layer has at least one opening;

wherein the light guide forms a portion of an outer surface of the device.

10. The light guide module according to claim 9 , further comprising a film layer, wherein the light shielding pattern layer is disposed on the film layer.

11. The light guide module according to claim 10 , further comprising an adhesion disposed between the light guide and the film layer and located at a periphery of the film layer so that an air gap is formed between the film layer and the light guide.

12. The light guide module according to claim 9 , wherein the light guide has at least one protrusion located at the opening of the light shielding pattern layer.

13. The light guide module according to claim 9 , wherein the light shielding pattern layer is an ink pattern layer and is printed on the light guide.

14. The light guide module according to claim 9 , wherein the light guide comprises a first portion and a second portion connected to the first portion, wherein a first refractive index of the first portion is greater than a second refractive index of the second portion, and the diffusing particles are distributed within the second portion.

15. The light guide module according to claim 14 , wherein a thickness of the second portion of the light guide is gradually increased from a first side of the light guide toward a second side opposite to the first side and a distance from the reflective surface to the second portion of the light guide is gradually decreased with the increase of the thickness of the second portion of the light guide, and one of the first side and the second side contains the side surface.

16. The light guide module according to claim 15 , wherein the light source is disposed beside the light guide on the first side or the second side.

17. The light guide module according to claim 9 , wherein the reflective surface is substantially flat.

18. The decoration panel according to claim 9 , wherein the light-exiting surface is uneven.
