DAYLIGHTING MEMBER, DAYLIGHTING DEVICE, AND INSTALLATION METHOD FOR DAYLIGHTING MEMBER
Document Type and Number:
WIPO Patent Application WO/2017/022792
Kind Code:
A1
Abstract:
A daylighting film (1) according to an aspect of the present invention is provided with: a first substrate (2); a plurality of daylighting parts (3) formed of a plurality of polygonal pillar structures; and gaps (9) provided between the plurality of daylighting parts (3). The cross sections, of the daylighting parts (3), orthogonal to the longitudinal direction each have a polygonal shape having four vertexes and having the internal angles all of which are less than 180°. The cross sections each include: a first side, which is one side of the polygonal shape, corresponding to the surface in contact with the first substrate (2); a first vertex and a second vertex which are both ends of the first side; and a plurality of vertices including a third vertex which is not positioned on the first side. A line which is perpendicular to the first side and which extends through the third vertex is longer than a line which is perpendicular to the first side and which extends through a vertex of the plurality of vertices excluding the third vertex. The shapes of the daylighting parts (3) are each asymmetric about the line which is perpendicular to the first side and which extends through the third vertex.
