DAYLIGHTING SHEET AND DAYLIGHTING DEVICE
To provide a daylighting sheet capable of changing a direction of light from an outdoor side into a desired direction and suppressing dew condensation in the inside, and daylighting device using the daylighting sheet.SOLUTION: The daylighting sheet includes: a light transmissive base material 11; a plurality of unit prisms 12 extending in a first direction parallel to a first principal surface in a first principal surface 11a side of the light transmissive base material and disposed along a second direction parallel to the first principal surface and orthogonal to the first direction; and first partition parts 17 lie between a first unit prism and an adjacent second unit prism, out of the plurality of disposed unit prisms. The first partition part comes into contact with both of a part of a first inclined plane forming one of first groove portion and a part of a second inclined plane forming the other of the first groove portion so as to partially block the first groove portion 18 formed by the first unit prism and the second unit prism.SELECTED DRAWING: Figure 1
【課題】室外側からの光を所望の向きに方向転換させることができ、かつ、内部の結露を抑制できる採光シート、およびそれを用いた採光具を提供する。【解決手段】採光シートは、光透過性基材１１と、光透過性基材の第１主面１１ａ側の第１主面に平行な第１方向に延在し、かつ、第１主面と平行で第１方向と交差する第２方向に沿って複数配置された単位プリズム１２と、を備え、複数配置された単位プリズムのうち、第１単位プリズムおよび隣接する第２単位プリズムに跨る第１仕切部１７を備え、第１仕切部は第１単位プリズムおよび第２単位プリズムによって形成される第１溝部１８を部分的に塞ぐように、第１溝部の一方を形成する第１斜面の一部と、第１溝部の他方を形成する第２斜面の一部と、の両方に当接している。【選択図】図１
