Abstract: A daylighting system (1) according to one aspect of the invention includes a daylighting apparatus (2) and an artificial light source apparatus (3) that emits light toward the daylighting apparatus (2). The daylighting apparatus (2) includes a base material (4) having light transmission property, and a plurality of daylighting portions (5) that are provided on a first surface of the base material (4), have light transmission properties and reflect light incident from a light incident end surface on a reflection surface. The artificial light source apparatus (3) emits at least light that enters the daylighting portions (5) from the light incident end surface and travels toward the reflection surface.

Abstract: A light control system includes a daylighting unit that takes in outside light, a lighting unit that is able to adjust an output of light, an acquisition unit that acquires brightness information representing brightness, including at least brightness of the outside light taken in from the daylighting unit, and a control unit that controls the output of light toward a target value. The control unit changes the target value based on the brightness information.

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.
