Abstract

An illumination apparatus includes a woven fabric in which optical fibers are woven as a constituent yarn and a light source. The illumination apparatus makes light delivered from the light source incident upon the end surfaces on one end side of the optical fibers and emits the light at least from the end surfaces on the other end side of the optical fibers for illumination. The other end side of the optical fibers is exposed from the woven fabric to constitute exposed parts, and the end parts of a plurality of the exposed parts on the other end side are supported by an end part support to form emitting parts which emit light from the light source. On the end part support, the end parts of the exposed parts on the other end side are individually supported such that their respective end surfaces are aligned on the same plane.

First claim

What is claimed is:

1. An illumination apparatus comprising a woven fabric in which optical fibers are woven as a constituent yarn and a light source, the illumination apparatus making light delivered from the light source incident upon end surfaces on one end side of the optical fibers and emitting the light at least from end surfaces on an other end side of the optical fibers for illumination,
wherein the other end side of the optical fibers is exposed from the woven fabric to define exposed parts on the other end side;
wherein the end parts of the plurality of the exposed parts on the other end side are supported by at least one end part support to form emitting parts which emit light delivered from the light source;
wherein, on the end part support, the end parts of the plurality of the exposed parts on the other end side are individually supported in a state where their respective end surfaces are aligned on the same plane, and wherein
the at least one end part support is separate from the woven fabric.

2. The illumination apparatus according to claim 1 , wherein
side-emitting optical fibers are used as the optical fibers.

3. The illumination apparatus according to claim 1 , wherein
the at least one end part support comprises a plurality of end part supports each supporting allocated ones of the end parts of the plurality of the exposed parts on the other end side.

4. The illumination apparatus according to claim 1 , wherein
a plurality of groove parts are formed, along the length direction of the optical fibers, in the at least one end part support, and the end parts of the exposed parts on the other end side are engaged with and supported by the plurality of groove parts.

5. The illumination apparatus according to claim 2 , wherein
the at least one end part support comprises a plurality of end part supports each supporting allocated ones of the end parts of the plurality of the exposed parts on the other end side.

6. The illumination apparatus according to claim 2 , wherein
a plurality of groove parts are formed, along the length direction of the optical fibers, in the at least one end part support, and the end parts of the exposed parts on the other end side are engaged with and supported by the plurality of groove parts.

7. The illumination apparatus according to 3 , wherein
a plurality of groove parts are formed, along the length direction of the optical fibers, in the at least one end part support, and the end parts of the exposed parts on the other end side are engaged with and supported by the plurality of groove parts.

8. The illumination apparatus according to claim 5 , wherein
a plurality of groove parts are formed, along the length direction of the optical fibers, in the at least one end part support, and the end parts of the exposed parts on the other end side are engaged with and supported by the plurality of groove parts.

9. The illumination apparatus according to claim 1 , wherein the exposed parts on the other end side extend from the woven fabric such that the emitting parts are configured to be freely arranged around the woven fabric.

10. The illumination apparatus according to claim 2 , wherein the exposed parts on the other end side extend from the woven fabric such that the emitting parts are configured to be freely arranged around the woven fabric.

11. The illumination apparatus according to claim 3 , wherein the exposed parts on the other end side extend from the woven fabric such that the emitting parts are configured to be freely arranged around the woven fabric.

12. The illumination apparatus according to claim 4 , wherein the exposed parts on the other end side extend from the woven fabric such that the emitting parts are configured to be freely arranged around the woven fabric.

13. The illumination apparatus according to claim 1 , wherein the exposed parts have an un-supported intermediate portion defined between an outer side edge of the woven fabric and a side edge of the at least one end part support that is nearest the one support.

14. The illumination apparatus according to claim 2 , wherein the exposed parts have an un-supported intermediate portion defined between an outer side edge of the woven fabric and a side edge of the at least one end part support that is nearest the one support.

15. The illumination apparatus according to claim 3 , wherein the exposed parts have an un-supported intermediate portion defined between an outer side edge of the woven fabric and a side edge of the at least one end part support that is nearest the one support.

16. The illumination apparatus according to claim 4 , wherein the exposed parts have an un-supported intermediate portion defined between an outer side edge of the woven fabric and a side edge of the at least one end part support that is nearest the one support.

17. The illumination apparatus according to claim 4 , wherein the plurality of groove parts are defined by a plurality of linear channels extending in a longitudinal direction of the optical fibers and receiving the end parts of the plurality of the exposed parts.

18. The illumination apparatus according to claim 6 , wherein the plurality of groove parts are defined by a plurality of linear channels extending in a longitudinal direction of the optical fibers and receiving the end parts of the plurality of the exposed parts.

19. The illumination apparatus according to claim 7 , wherein the plurality of groove parts are defined by a plurality of linear channels extending in a longitudinal direction of the optical fibers and receiving the end parts of the plurality of the exposed parts.

20. The illumination apparatus according to claim 8 , wherein the plurality of groove parts are defined by a plurality of linear channels extending in a longitudinal direction of the optical fibers and receiving the end parts of the plurality of the exposed parts.
