DAYLIGHTING SHEET AND DAYLIGHTING DEVICE
PROBLEM TO BE SOLVED: To provide a daylighting sheet which allows for directing sunlight entering through windows to a ceiling inside a building which is not directly irradiated when the sunlight enters at usual incident angles, converting the sunlight into diffusion light that is uniformly diffused in an opening direction, and efficiently irradiating a ceiling surface, innermost wall surfaces furthest from the windows and the like inside the building while suppressing color separation.SOLUTION: A daylighting film comprises a first base material 2 and a second base material 4 laminated together. The first base material 2 has therein a crazed region consisting of molecular bundles and micropores and extending in stripes along a first direction D1. The second base material 4 has protrusions and recesses repeatedly arranged along the first direction D1, forming a concavo-convex pattern that irregularly meanders about a second direction D2 crossing the first direction D1 such that inter-ridge distance varies among ridge lines comprising apexes of the protrusions of the concavo-convex pattern.SELECTED DRAWING: Figure 2
【課題】窓に入射した太陽光を通常の入射角度では直接照射されない建物内の天井に導き、且つ、間口方向に均斉化された拡散光とすることができ、建物内の天井面及び窓側から最も離れた最奥部壁面等を効率よく、色の分離を抑えて照らすことができる採光シートを提供する。【解決手段】第一基材２と、第二基材４が重ねて配される採光シートであって、第一基材２の内部には、分子束と微細孔からなり、第一方向Ｄ１に沿って縞状に延びるクレーズ領域が形成され、第二基材４には、第一方向Ｄ１に沿って凹凸が繰り返され、且つ前記凹凸の凸部の頂点からなる複数の稜線同士の間隔がばらつくように各々不規則に、第一方向Ｄ１に交差する第二方向Ｄ２を中心に蛇行した波状の凹凸パターンが形成されている採光シート１。【選択図】図２
