PROBLEM TO BE SOLVED: To provide a light guide system and a ceiling structure capable of irradiating the surface of a table within a space main body (a room, for example) like a perpendicular form with solar light and effectively increasing illumination intensity at the table surface.SOLUTION: This invention relates to a light guide system and a ceiling structure. The light guide system includes each of a first light guide element and a second light guide element provided at each of a first plane and a second plane of a space main body. The second light guide element includes a plurality of light guide structures, each of the light guide structures is provided with a first surface and a second surface, after a light beam from the first light guide element is inflected at the first surface, it enters the light guide structures and further it is reflected toward the second surface and after inflected at the second surface, it is emitted. |
