Abstract

In order to provide a light emitting decoration, a method for laying a light emitting decoration, a laying object, and a method for forming a light emitting design, each which provides a light emitting design having excellent visibility with less light emission source and energy consumed, the light emitting decoration includes: a woven fabric having a side emission optical fiber woven in a line shape over one end side and the other end side, and the woven fabric is visually recognized in a state where the other end side is located on the front side and the one end side is located on the back side; and a light source which introduces light to advance from the one end side toward the other end side in the optical fiber. The laying object includes the light emitting decoration laid thereon.

Claims

1. A light emitting decoration comprising:

a woven fabric having a side emission optical fiber woven in a line shape over one end side and the other end side, and the woven fabric is visually recognized in a state where the other end side is located on the front side and the one end side is located on the back side; and

a light source that introduces light to advance from the one end side toward the other end side in the optical fiber.

2. The light emitting decoration according to claim 1, wherein the optical fiber is a weft in the woven fabric.

3. The light emitting decoration according to claim 1,

wherein the woven fabric is laid on a design surface of a door trim for a vehicle, and

wherein the one end side is located on a front side of a vehicle and the other end side is located on a rear side of the vehicle.

4. The light emitting decoration according to claim 1,

wherein the woven fabric is laid on a design surface of a ceiling for a vehicle, and

wherein the one end side is located on a front side of a vehicle and the other end side is located on a rear side of the vehicle.

5. A laying object comprising a light emitting decoration laid thereon, the light emitting decoration comprising:

a woven fabric having a side emission optical fiber woven in a line shape over one end side and the other end side; and

a light source that introduces light to advance from the one end side toward the other end side in the optical fiber,

wherein the woven fabric is laid so that the woven fabric is visually recognized in a state where the other end side of the woven fabric is located on the front side and the one end side is located on the back side.

6. The laying object according to claim 5, wherein the optical fiber is a weft in the woven fabric.

7. The laying object according to claim 5,

wherein the woven fabric is laid on a design surface of a door trim for a vehicle, and

wherein the one end side is located on a front side of a vehicle and the other end side is located on a rear side of the vehicle.

8. The laying object according to claim 5,

wherein the woven fabric is laid on a design surface of a ceiling for a vehicle, and

wherein the one end side is located on a front side of a vehicle and the other end side is located on a rear side of the vehicle.

9. A method for laying a light emitting decoration, the light emitting decoration comprising:

a woven fabric having a side emission optical fiber woven in a line shape over one end side and the other end side; and

a light source that introduces light to advance from the one end side toward the other end side in the optical fiber,

the method comprising laying the woven fabric so that the woven fabric is visually recognized in a state where the other end side of the woven fabric is located on the front side and the one end side is located on the back side.

10. The method for laying a light emitting decoration according to claim 9, wherein the optical fiber is a weft in the woven fabric.

11. The method for laying a light emitting decoration according to claim 9, wherein the woven fabric is laid on a design surface of a door trim for a vehicle so that the one end side is located on a front side of a vehicle, and that the other end side is located on a rear side of the vehicle.

12. The method for laying a light emitting decoration according to claim 9, wherein the woven fabric is laid on a design surface of a ceiling for a vehicle so that the one end side is located on a front side of a vehicle, and that the other end side is located on a rear side of the vehicle.

13. A method for forming a light emitting design for forming a light emitting design using a woven fabric having a side emission optical fiber woven in a line shape over one end side and the other end side,

the method comprising introducing light in the optical fiber so that the light advances from the one end side toward the other end side when the light emitting design is visually recognized in a state where the other end side of the woven fabric is located on the front side and the one end side thereof is located on the back side.

14. The method for forming a light emitting design according to claim 13, wherein the optical fiber is a weft in the woven fabric.

15. The method for forming a light emitting design according to claim 13,

wherein the woven fabric is laid on a design surface of a door trim for a vehicle, and

wherein the one end side is located on a front side of a vehicle and the other end side is located on a rear side of the vehicle.

16. The method for forming a light emitting design according to claim 13,

wherein the woven fabric is laid on a design surface of a ceiling for a vehicle, and

wherein the one end side is located on a front side of a vehicle and the other end side is located on a rear side of the vehicle.
