<P>PROBLEM TO BE SOLVED: To provide a flexible light-transmitting body capable of switching a light source to a desired lighting direction at a fixed state without moving the light source, a multilayer flexible light-transmitting body made by a multilayer structure, a lighting device compactly structured by using the flexible light-transmitting body, and a solar panel light-receiving device capable of simply forming a solar light-receiving system which can effectively receive light by following movement of sunlight. <P>SOLUTION: The flexible light-transmitting body 1 has diffraction gratings 2 formed on front and back surfaces of a PC resin plate 3 having flexibility and light permeability, and forms a light-transmitting medium where both end surfaces of the PC resin plate 3 are set up to be an incident end surface 4 and an emitting end surface 5, respectively. The light introduced to the incident end surface 4 of the resin plate 3 can be emitted from the emitting end surface 5 by transmitting it through the resin plate 3 while the introduced light is diffracted by the diffraction grating 2 at a state that the resin plate 3 is deformed at a desired bending shape. <P>COPYRIGHT: (C)2010,JPO&INPIT |
