Title: DAYLIGHTING DEVICE
Abstract:
A daylighting device according to one mode of the present invention is provided with: a daylighting member that has a base material in which at least a part thereof is light-transmissive, a plurality of light-transmissive first daylighting parts provided on a first surface of the base material, and light-transmissive gaps provided between the plurality of daylighting parts; and a support member that supports the daylighting member. Portions of lateral surfaces of the daylighting parts in contact with the gaps serve as reflection surfaces that reflect light incident on the daylighting parts. The daylighting parts have characteristics of dispersing and emitting light reflected on the reflection surfaces in directions crossing a direction in which the daylighting parts extend. The plurality of daylighting parts extend at an angle of -45 to +45° with respect to an end edge of the base material along the vertical direction.
