LIGHTING SHEET AND LIGHTING TOOL
To provide a lighting sheet that can change the direction of light from the outdoors to a desired direction and prevent dew condensation therein, and to provide a lighting tool using the lighting sheet.SOLUTION: A lighting sheet comprises: a light transmissive substrate 11; and unit prisms 12 that extend in a first direction parallel to a first principal surface 11a of the light transmissive substrate 11 and are arranged in plurality along a second direction parallel to the first principal surface and intersecting the first direction. The unit prisms 12 each have a first inclined surface 12a and a second inclined surface 12b extending in the first direction, which form a part of an outer face; one end of the first inclined surface 12a intersects the first principal surface 11a, and the other end extends in a direction separating from the first principal surface 11a; one end of the second inclined surface 12b intersects the first principal surface 11a at a position separated from one end of the first inclined surface 12a along the second direction, and the other end extends in the direction separating from the first principal surface 11a; the unit prisms 12 each include a water-repellent layer 71 having water repellency at least on the first inclined surface 12a or the second inclined surface 12b.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、内部の結露を抑制できる採光シートを提供する。また、当該採光シートを用いた採光具を提供する。【解決手段】光透過性基材１１と、光透過性基材１１の第１主面１１ａに平行な第１方向に延在し、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とを備えた採光シートであって、単位プリズム１２は外面の一部を形成する、第１方向に延在する第１斜面１２ａおよび第２斜面１２ｂを有し、第１斜面１２ａの一端は第１主面１１ａと交差し、他端は第１主面１１ａから離れる方向に延びており、第２斜面１２ｂの一端は第１斜面１２ａの一端とは第２方向に沿って離隔した位置で第１主面１１ａと交差し、他端は第１主面１１ａから離れる方向に延びており、単位プリズム１２は、少なくとも第１斜面１２ａまたは第２斜面１２ｂにおいて、撥水性を有する撥水層７１を備えている。【選択図】図１
