| 摘要 |
The present invention relates to an optical surface device especially usefully integrated into multi layer optical laminations for the diffusing of light as illumination or for the concentrating of light. The device of the present invention is comprised of (a) at least one side emitting optical fiber and the fiber is convoluted to effectively cover a surface area, and (b) means for holding the fiber in the surface area covering convolution. Furthermore, at least one of each of the fibers' end portions either is accessible for receiving light from at least one light source unit (for the illuminator embodiments) or is accessible for transferring light to at least one light emitting unit (for the concentrator embodiments).
