Description

  The present invention relates to a daylighting system that is used for taking light such as sunlight into a veranda of a building to ensure brightness.

  It is well known that the window glass is used to form a bright and comfortable indoor space by taking in outside light such as sunlight inside the building. However, on the other hand, if the outside light incident on the window glass is taken into the room as it is, problems such as feeling dazzling or being limited to a part of the room where the light hits may occur. On the other hand, a technique has been proposed in which sunlight is directly controlled and light is taken indoors in a more comfortable manner.

For example, in Patent Document 1 (Japanese Patent Laid-Open No. 2012-255951), a concave groove extending in one direction is repeatedly produced, and incident light to the transparent sheet material is reflected by filling the concave groove with the filler. A light control member (lighting sheet) is disclosed in which a reflecting surface extending in one direction is formed on at least one slope of a concave groove, and direct sunlight transmitted through a window is introduced indoors by reflection by the reflecting surface.
JP 2012-255951 A

  Even if the lighting effect to the room by the light control member (lighting sheet) as described above is sufficient, the depth of the veranda is limited, so that the sun does not reach the ceiling of the veranda and the veranda is sufficient. There was a problem that it was not possible to ensure a sufficient brightness.

  In recent years, verandas have been used not only as clothes drying and gardening areas, but also as part of living spaces, and it has been necessary to improve the brightness by daylighting as well as indoors. Daylighting was not considered enough and was a problem.

The present invention is for solving the above-described problems, and a daylighting system according to the present invention is a daylighting system provided on a veranda of a building, wherein the first main surface on which light is incident, and the first A first light control member that has a second main surface that faces one main surface and emits light, and that deflects light incident from the first main surface toward the second main surface; And a second light control member for deflecting light emitted from the light control member toward the first light control member.

  The daylighting system according to the present invention is characterized in that the veranda has a roof portion, and the light deflected by the second light control member is irradiated to the roof portion.

  The daylighting system according to the present invention is characterized in that the first light control member is disposed between a floor portion of a veranda and a fall prevention handrail portion.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Hereinafter, first, the outline of the configuration of the first light control member 10 used in the present invention will be described.

  FIG. 1 is a diagram for explaining the effect of the first light control member 10. FIG. 1 (A) shows the intake of sunlight from a normal window, and FIG. 1 (B) shows the case where the first light control member 10 is attached to the window and the sunlight is introduced. Show. By providing the first light control member 10 in the window, it is possible to achieve daylighting that brightens the entire interior as uniformly as possible.

  Here, in the following description, coordinates for clarifying the direction and positional relationship of each component are defined. A right-handed system coordinate is defined in which the direction parallel to the horizontal side and direction of the window portion is the x direction and the vertically upward direction is the z direction, and is used for the following description. In the drawings attached to the present specification, such right-handed system coordinates are described for reference as necessary.

  An example of the first light control member 10 used in the present invention will be described. FIG. 2 is a diagram schematically illustrating the cross-sectional structure of the first light control member 10. Note that in the drawings attached to the present specification, for the sake of illustration and ease of understanding, the scale, vertical and horizontal dimensional ratios, and the like may be appropriately changed or exaggerated from those of the actual product. In addition, from the viewpoint of easy viewing of the drawings, reference numerals are omitted for configurations that repeat periodically.

  As shown in FIG. 2, the first light control member 10 has a first main surface 11 on which light is incident and a second main surface 12 that faces the first main surface 11 and emits light, A plurality of low-refractive index medium portions 16 that exist between the first main surface 11 and the second main surface 12 and deflect light incident from the first main surface 11 toward the second main surface 12. And comprising.

  The first light control member 10 typically includes a plurality of low refractive index medium portions 16 that extend in the vertical direction (x direction) on the paper surface and are periodically provided in the vertical direction (z direction) on the paper surface. And a high refractive index medium portion 15 that separates the refractive index medium portions 16. In this case, the interface between the low refractive index medium portion 16 and the high refractive index medium portion 15 is a reflective surface. The low refractive index medium section 16 is configured by a medium having a refractive index lower than that of the high refractive index medium section 15. For example, when the high refractive index medium portion 15 is a resin, the low refractive index medium portion 16 can be made of air or a resin having a lower refractive index than the resin constituting the high refractive index medium portion 15.

  The light L1 incident on the first main surface 11 proceeds to the first light control member 10 and is reflected and deflected by the reflecting surface. Thereafter, the deflected light L1 is emitted from the second main surface 12 facing the first main surface 11 and travels outside the first light control member 10.

  In addition, like the light L2 incident on the first main surface 11, the light proceeds to the first light control member 10, and is deflected by being refracted at the interface between the low refractive index medium portion 16 and the high refractive index medium portion 15. There is also light that exits from the second major surface 12 and travels out of the first light control member 10.

  The first light control member 10 having the above functions may be a light control film manufactured from an organic polymer resin material, or may be a light control glass manufactured from an inorganic glass material. .

  Moreover, although the example of the structure which distribute | arranges the some low refractive index medium part 16 in the high refractive index medium part 15 as the 1st light control member 10 was demonstrated, it replaced with the some low refractive index medium part 16 For example, a plurality of highly reflective materials such as metals may be arranged in the first light control member 10.
