Abstract: 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.

Abstract: An optical coupling apparatus for coupling a waveguide to a light source, when the light source emits light at a divergence angle that is larger than the critical angle of the waveguide. The optical coupler comprises a plurality of light-guides, preferably cut from the edge of the waveguide. The light-guides are arranged to connect the waveguide to the light source via a plurality of orientations so that the entire divergence angle is covered within the critical angle of the light-guides.

Abstract: An illumination apparatus, comprising at least one light emitting source embedded in a waveguide material is disclosed. The waveguide material is capable of propagating light generated by light emitting source(s), such that at least a portion of the light is diffused within the waveguide material and exits through at least a portion of its surface.
