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.

First claim

What is claimed is:

1. A light emitting decoration comprising:
a woven fabric having a side emission optical fiber woven in a line from one end side to 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 in a light advancing direction from the one end side toward the other end side in the optical fiber,
wherein when a luminance of the optical fiber observed at a position substantially perpendicular to the light advancing direction is L 0 , a luminance of the side emission optical fiber observed from a position at an angle of 30 degrees from a line substantially perpendicular to the light advancing direction toward the other end side is L 30 , a luminance of the side emission optical fiber observed from a position at an angle of 60 degrees from the line substantially perpendicular to the light advancing direction toward the other end side is L 60 , a luminance of the side emission optical fiber observed from a position at an angle of 60 degrees from the line substantially perpendicular to the light advancing direction toward the one end side is L −60 , the optical fiber satisfies L −60 <L 30 and L 30 /L 0 <L 60 /L 30 .

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 from one end side to the other end side; and
a light source that introduces light to advance in an advancing direction 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,
wherein when a luminance of the optical fiber observed at a position substantially perpendicular to the light advancing direction is L 0 , a luminance of the side emission optical fiber observed from a position at an angle of 30 degrees from a line substantially perpendicular to the light advancing direction toward the other end side is L 30 , a luminance of the side emission optical fiber observed from a position at an angle of 60 degrees from the line substantially perpendicular to the light advancing direction toward the other end side is L 60 , a luminance of the side emission optical fiber observed from a position at an angle of 60 degrees from the line substantially perpendicular to the light advancing direction toward the one end side is L −60 , the optical fiber satisfies L −60 <L 30 and L 30 /L 0 <L 60 /L 30 .

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 from one end side to the other end side; and
a light source that introduces light to advance in an advancing direction 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,
wherein when a luminance of the optical fiber observed at a position substantially perpendicular to the light advancing direction is L 0 , a luminance of the side emission optical fiber observed from a position at an angle of 30 degrees from a line substantially perpendicular to the light advancing direction toward the other end side is L 30 , a luminance of the side emission optical fiber observed from a position at an angle of 60 degrees from the line substantially perpendicular to the light advancing direction toward the other end side is L 60 , a luminance of the side emission optical fiber observed from a position at an angle of 60 degrees from the line substantially perpendicular to the light advancing direction toward the one end side is L −60 , the optical fiber satisfies L −60 <L 30 and L 30 /L 0 <L 60 /L 30 .
