초록 ▼

A flexible and optionally highly elastic waveguide capable of propagating and emitting light is disclosed. The flexible waveguide comprises a flexible material having a surface and an end, wherein a first portion of the light is emitted through at least a portion of the surface of the flexible waveguide, and a second portion of the light is emitted through the end. The flexible waveguide can be used, for example as an area illuminator for many applications. Additionally disclosed is a clothing device for providing illumination. The clothing device comprises clothing (or even optionally a sheet) and a light source for providing light. In one embodiment the clothing device comprises the flexible waveguide.

The device of claim 1, wherein said waveguide material is designed and constructed to allow propagation of a portion of said light therein by total internal reflection. 15. The device of claim 1, wherein said ambient electromagnetic field is other than any light. 16. The device of claim 1, wherein said ambient electromagnetic field is in the visible range. 17. The device of claim 1, wherein said ambient electromagnetic field is in the non-visible range. 18. The device of claim 1, wherein said ambient electromagnetic field is in the infrared range. 19. The device of claim 1, wherein said ambient electromagnetic field is in the ultraviolet range. 20. The device of claim 1, wherein said plurality of particles comprises a plurality of chromogenes. 21. The device of claim 1, wherein said plurality of particles comprises a plurality of discrete quantum dots. 22. The device of claim 1, wherein said plurality of particles comprises a plurality of nanocrystals. 23. The device of claim 1, wherein said waveguide material is a layered structure and wherein said particles are distributed in at least one layer of said layered structure. 24. The device of claim 1, wherein said waveguide material comprises at least three layers and wherein said particles are distributed in an intermediate layer of said at least three layers. 25. The device of claim 1, wherein said waveguide material is a layered structure and wherein said particles are distributed in an outer layer of said layered structure.
