Abstract
A daylighting apparatus of the present invention includes: a daylighting sheet (13) that has first and second surfaces opposite to each other and that lets light in through the first surface and lets the light out through the second surface at a predetermined distribution of angles; and a visible light-reflecting sheet (15) that reflects part of visible light falling on the first surface of the daylighting sheet (13).
Claims18
A daylighting apparatus comprising:
- a daylighting member that allows transmittance of external visible light from an incident surface through an emitting surface at a predetermined distribution of angles, the daylighting member comprising:
- a first substrate;
- a plurality of daylighting portions arrayed, in one direction, on an incident surface of the first substrate;
- and
- a void part provided between the plurality of daylighting portions;
- and
- a reflecting member comprising a predetermined pattern that reflects part of the visible light and transmits another part of the visible light falling on the incident surface of the daylighting member;
- wherein
- the reflecting member is provided to oppose at least part of the incident surface of the daylighting member.

A daylighting apparatus comprising:
- a daylighting member that has first and second surfaces opposite to each other and that lets light in through the first surface and lets the light out through the second surface at a predetermined distribution of angles, the daylighting member comprising:
- a first substrate having third and fourth surfaces opposite to each other, the third surface being at a side of the first surface, the fourth surface being at a side of the second surface;
- a plurality of daylighting portions arrayed, in one direction, on the third surface;
- and a void part provided between the plurality of daylighting portions;
- and
- a reflecting member that reflects part of visible light so as to be recognized by an observer as a predetermined pattern, and transmits another part of the visible light falling on the first surface, wherein
- the reflecting member further has a function of transmitting the visible light, wherein
- the reflecting member has a reflectance that varies, in one in-plane direction, the reflectance varying in a period which is from 20 mm to 40 mm, and
- there is a coincidence between a first direction in which the reflectance varies in the period and a second direction in which the plurality of daylighting portions are arrayed.

- and
- a reflecting member that reflects part of visible light so as to be recognized by an observer as a predetermined pattern, and transmits another part of the visible light falling on the first surface, wherein
- the reflecting member comprises a plurality of patterns having different areas such that the observer recognizes the predetermined pattern by reflecting, by the plurality of patterns, the part of the visible light, wherein
- each shape of the plurality of patterns is one of circular or quadrangular.
