Abstract

A light emitting fabric (10) in which optical fibers (12, 28, 46, 48) are part of the weave, replacing some of the threaded fibers (27), whereby the fabric is uniformly illuminated and, accordingly, decorated. The individual optical fibers are gathered into a bundle (15) at one end of the fabric and illuminated by a light source (17). Light traveling through the fibers is emitted in small amounts throughout the lengths thereof through small scratches (14) that pierce the outer coating. Uniformity and intensity of light are enhanced by providing a reflective coating (13) on the non-illuminated ends of the optical fibers. This fabric is usable in clothing; such as costumes, high visibility safety clothing, suntan suits (21); rugs, draperies, theater curtains, architectural panels (23), fiberglass boat hulls, and the like.

Claims

1. A light emitting fabric comprising a woven plurality of optical fibers, each of which fibers is deformed at discrete intervals along the length thereof to allow light to radiate therefrom.

2. A light emitting fabric as set forth in claim 1, including a source of illumination and a means for connecting said source of illumination to said woven plurality of optical fibers.

3. A light emitting fabric as set forth in claim 1, wherein said optical fibers comprise the warp fibers of said fabric.

4. A light emitting fabric as set forth in claim 1, wherein said optical fibers comprise the woof fibers of said fabric.

5. A light emitting fabric as set forth in claim 1, wherein said optical fibers are used as both warp and woof fibers in said fabric.

6. A light emitting fabric as set forth in claim 1, wherein the deformaties located at discrete intervals along the length of said optical fibers consist of notches cut into said fibers.

7. A light emitting fabric as set forth in claim 6, wherein the distances between successive notches along the length of each said optical fiber progressively decrease in proportion to the distances between the source of illumination and the notches to provide for uniform emission of light along the length of each said fiber.

8. A light emitting fabric as set forth in claim 6, wherein the distances between successive notches along the length of each said optical fiber vary in a predetermined manner to cause said light emitting fabric to radiate light in a predetermined visual pattern.

9. A light emitting fabric as set forth in claim 6, wherein the depth of the notches along the length of each said optical fiber is varied in a predetermined manner to cause said light emitting fabric to radiate light in a predetermined visual pattern.

10. A light emitting fabric as set forth in claim 2, wherein said connecting means connects said source of illumination to one end of each of the optical fibers comprising said woven plurality of optical fibers.

11. A light emitting fabric as set forth in claim 10, wherein all of the adjacent optical fiber ends along a first edge of said light emitting fabric extend beyond said edge and are bundled together for connection to said source of illumination.

12. A light emitting fabric as set forth in claim 11, wherein the optical fiber ends opposite the ends connected to said source of illumination are coated with a reflective substance to redirect light from the coated ends back into the optical fibers.

13. A light emitting fabric as set forth in claim 11, wherein each successive pair of optical fibers is formed from a single optical fiber element, which element is connected at both of its ends to said source of illumination and is looped at the edge of the fabric opposite said first edge to create adjacent optical fibers.

14. A light emitting fabric as set forth in claim 11, wherein said connecting means includes an optical coupler which connects said bundled optical fiber ends to said source of illumination.

15. A light emitting fabric as set forth in claim 2, wherein said connecting means includes a color filtering means which causes colored light to enter said woven plurality of optical fibers.

16. A light emitting fabric as set forth in claim 15, wherein said color filtering means is capable of varying the color of the light in said optical fibers as a function of time.

17. A light emitting fabric as set forth in claim 1, wherein the core of said optical fibers consists of a colored translucent material which causes colored light to be emitted from said fibers.

18. A light emitting fabric as set forth in claim 1, wherein said fabric is coated with a protective coating means to prevent damage thereto from the effects of weather and corrosive chemicals.

19. An article of clothing constructed from a light emitting fabric as defined in claim 1.

20. A light emitting fabric as set forth in claim 1 including a fiberglass panel of predetermined shape, said light emitting fabric being embedded within said fiberglass panel.

21. A light emitting fabric as set forth in claim 20, wherein said fiberglass panel includes a source of illumination and a means for connecting said source of illumination to said woven plurality of optical fibers.

22. Wallpaper comprised of light emitting fabric as defined in claim 1.

23. A light emitting fabric as set forth in claim 1, wherein said fabric is mounted upon a rigid backing means of predetermined shape to provide support for said fabric.

24. A light emitting fabric as set forth in claim 23, wherein said rigid backing means includes a source of illumination and a means for connecting said source of illumination to said woven plurality of optical fibers.

25. A light emitting fabric as set forth in claim 23, wherein said rigid backing means is formed from metal.

26. A light emitting fabric as set forth in claim 23, wherein said rigid backing means is formed from a cellulose substance.

27. A light emitting fabric as set forth in claim 1, wherein said fabric is mounted between two sheets of glass.

28. A light emitting fabric as set forth in claim 1, wherein said light emitting fabric is embedded within a translucent glass panel.

29. A heat emitting fabric comprising a woven plurality of optical fibers, each of which fibers is deformed at discrete intervals along the length thereof to allow infrared radiation to radiate therefrom.

30. A heat emitting fabric as set forth in claim 29, including a source of infrared radiation and a means for connecting said source of infrared radiation to said woven plurality of optical fibers.

31. A garment constructed from a heat emitting fabric as defined in claim 29, wherein all of the discrete intervals at which each said optical fiber is deformed are arranged to radiate infrared radiation toward the interior of said garment.

32. A heat emitting fabric as set forth in claim 29, wherein said heat emitting fabric is mounted upon a rigid backing means of predetermined shape to provide support for said fabric.

33. A garment woven from a plurality of optical fibers, each of which fibers is deformed at discrete intervals along the length thereof to allow ultraviolet radiation to radiate therefrom in a direction toward the interior of said garment.

34. A garment as set forth in claim 33, including a source of ultraviolet radiation and a means for connecting said source of ultraviolet radiation to said woven plurality of optical fibers.

35. A garment as set forth in claim 34, including a timing means to regulate the amount of ultraviolet radiation radiating from said optical fibers as a function of time.
