Abstract: A wavelength conversion element includes a plate, a wavelength conversion layer, and a macromolecular layer. The wavelength conversion layer has a facing surface facing the plate. The wavelength conversion layer contains an inorganic wavelength conversion material that emits light of a wavelength different from the wavelength of incident light. The macromolecular layer is disposed between the plate and the wavelength conversion layer. A part of the facing surface is in contact with the plate. At least a part of another portion of the facing surface is joined to the plate with the macromolecular aver interposed.

Abstract: A daylighting device according to an aspect of the invention includes at least a daylighting film that includes a base having optical transparency and daylighting portions having optical transparency and provided on one surface of the base. Each of the daylighting portions has a reflective surface by which light incident on the daylighting portion is reflected and the light reflected by the reflective surface and output from a second surface of the base has a characteristic that the light travels toward a space on a side where the light is incident on the reflective surface, the space being one of two spaces divided by a virtual plane as a boundary which is vertical to the second surface of the first substrate and parallel to a direction of the daylighting portion extending, and intervals s between adjacent daylighting portions are set to various values.

Abstract: A daylighting blind according to an aspect of the invention includes: a plurality of slats; and a support mechanism that interconnects the plurality of slats, a longitudinal direction of which is oriented in a horizontal direction, and supports the plurality of slats suspended in a vertical direction. At a boundary between a daylighting slat group composed of a plurality of daylighting slats in an upper position in the vertical direction and a light-shielding slat group composed of a plurality of light-shielding slats in a lower position in the vertical direction, the daylighting slats and the light-shielding slats are arranged consecutively. The support mechanism includes a lifting/lowering member that causes the daylighting slat group to be stored or extend independently.
