（採光スクリーン１１）
　採光スクリーン１１は、図２Ａ，図２Ｂに示すように、光入射面（第１面）１１ａ側に配置された採光機能部１５と、採光機能部１５と光の透過方向で対向する光射出面（第２面）１１ｂ側に配置された光拡散機能部１６と、採光機能部１５と光拡散機能部１６との間に配置された遮光機能部１７とを備えている。
　遮光機能部１７は、複数の遮光スラット（スラット）７を有している。
　光入射面１１ａ側の採光機能部１５と、光射出面１１ｂ側の光拡散機能部１６は、複数の遮光スラット７の短手方向を介して対向する。 (Daylighting screen 11)
As shown in FIGS. 2A and 2B, the daylighting screen 11 includes a daylighting function unit 15 disposed on the light incident surface (first surface) 11a side, and a light emission surface that faces the daylighting function unit 15 in the light transmission direction. (2nd surface) The light diffusion function part 16 arrange | positioned at the 11b side and the light-shielding function part 17 arrange | positioned between the daylighting function part 15 and the light diffusion function part 16 are provided.
The light shielding function unit 17 includes a plurality of light shielding slats (slats) 7.
The lighting function unit 15 on the light incident surface 11 a side and the light diffusion function unit 16 on the light emission surface 11 b side face each other through the short direction of the plurality of light shielding slats 7.
　採光機能部１５は、図３に示すように、採光フィルム１５Ａと、採光フィルム１５Ａの一面側に貼り合わされる透過性部材１５Ｂとを備え、これらが一体化されて構成されている。
　採光フィルム１５Ａは、可視光透過性を有する基材１５ａと、遮光スラット７側の基材１５ａの一面側に設けられた可視光透過性を有する複数の採光部１５ｂと、複数の採光部１５ｂの間に設けられた空隙部１５ｃと、を有する。基材１５ａと複数の採光部１５ｂの構成材料は、互いに異なっていてもよいが、同じ材料であることが好ましい。基材１５ａは、複数の採光部１５ｂを支持する支持部材として機能する。採光フィルム１５Ａは、ＵＶ硬化樹脂もしくは熱硬化性樹脂を加工した採光フィルムからなる。 As shown in FIG. 3, the daylighting function unit 15 includes a daylighting film 15A and a transmissive member 15B bonded to one side of the daylighting film 15A, and these are integrated.
The daylighting film 15A includes a base material 15a having visible light permeability, a plurality of daylighting parts 15b having visible light permeability provided on one surface side of the base material 15a on the light shielding slat 7 side, and a plurality of daylighting parts 15b. And a gap 15c provided therebetween. The constituent materials of the base material 15a and the plurality of daylighting portions 15b may be different from each other, but are preferably the same material. The base material 15a functions as a support member that supports the plurality of daylighting portions 15b. The daylighting film 15A is a daylighting film obtained by processing a UV curable resin or a thermosetting resin.
　複数の採光部１５ｂは、基材１５ａの一面側に設けられている。複数の採光部１５ｂが設けられる面は、基材１５ａの遮光スラット７側の内面５ａであってもよいし、遮光スラット７とは反対側の外面５ｂであってもよい。 The plurality of daylighting portions 15b are provided on one side of the base material 15a. The surface on which the plurality of daylighting portions 15 b are provided may be the inner surface 5 a on the light shielding slat 7 side of the base material 15 a or the outer surface 5 b on the opposite side to the light shielding slat 7.
　各採光部１５ｂは、基材１５ａの一辺に沿って延在し、且つ、各々の延在方向に交差する方向に並んで設けられている。採光部１５ｂは、長手方向に交差する断面形状が、三角形状のプリズム体から構成されている。採光スクリーン１１の使用の際には、各採光部１５ｂの延在方向が水平方向に沿った状態で使用されることが望ましい。 Each of the daylighting portions 15b extends along one side of the base material 15a and is provided side by side in a direction intersecting with each extending direction. The daylighting portion 15b is configured by a prism body having a triangular cross section that intersects the longitudinal direction. When the daylighting screen 11 is used, it is desirable to use the daylighting unit 15b in a state where the extending direction of each daylighting portion 15b is along the horizontal direction.
　なお、採光部１５ｂの形状は、断面三角形状に限られず、断面五角形状、断面六角形状あるいはマルチテーパー形状であってもよく、特に限定されない。図３では、４個の採光部１５ｂのみを示しているが、実際にはより多数の採光部１５ｂが基材に設けられている。多数の採光部１５ｂを設けることにより、窓ガラス１００３を透過した太陽光が採光部１５ｂに入射すると、採光部１５ｂ内で反射して、斜め上方側に向かって出射する。 The shape of the daylighting portion 15b is not limited to a triangular cross section, and may be a pentagonal cross section, a hexagonal cross section, or a multitaper shape, and is not particularly limited. In FIG. 3, only four daylighting parts 15b are shown, but in reality, a larger number of daylighting parts 15b are provided on the base material. By providing a large number of daylighting parts 15b, when sunlight transmitted through the window glass 1003 enters the daylighting part 15b, it is reflected in the daylighting part 15b and emitted obliquely upward.
　複数の採光部１５ｂの間には、空隙部１５ｃが介在している。そのため、スネル（Ｓｎｅｌｌ）の法則より、採光部１５ｂに入射した光のうち、採光部１５ｂの反射面（不図示）で反射する光の臨界角が最も小さくなる。これにより、反射面で全反射する光の臨界角が最も小さくなる。よって、反射面で全反射される光の入射角の範囲が最も広くなることから、採光部１５ｂに入射した光を基材１５ａの光射出面１１ｂ側へと効率良く導くことができる。結果として、採光部１５ｂに入射した光の損失が抑えられ、基材１５ａの他面から出射される光の輝度を高めることができる。 Between the plurality of daylighting parts 15b, gaps 15c are interposed. Therefore, according to Snell's law, the critical angle of light reflected by the reflecting surface (not shown) of the daylighting unit 15b among the light incident on the daylighting unit 15b is the smallest. As a result, the critical angle of light totally reflected by the reflecting surface is minimized. Therefore, since the range of the incident angle of the light totally reflected by the reflecting surface becomes the widest, the light incident on the daylighting portion 15b can be efficiently guided to the light emitting surface 11b side of the base material 15a. As a result, the loss of light incident on the daylighting unit 15b is suppressed, and the luminance of light emitted from the other surface of the base material 15a can be increased.
　基材１５ａの屈折率と採光部１５ｂの屈折率とは、略同等であることが望ましい。すなわち、基材１５ａと採光部１５ｂとは、一体に形成されていることが望ましい。例えば、基材１５ａの屈折率と採光部１５ｂの屈折率とが大きく異なる場合、光が採光部１５ｂから基材１５ａに入射したときに、採光部１５ｂと基材１５ａとの界面で不要な光の屈折もしくは反射が生じることがある。この場合、所望の採光特性が得られない、輝度が低下する、などの不具合が生じるおそれがあるからである。 Desirably, the refractive index of the base material 15a and the refractive index of the daylighting portion 15b are substantially equal. That is, it is desirable that the base material 15a and the daylighting portion 15b are integrally formed. For example, when the refractive index of the base material 15a and the refractive index of the daylighting unit 15b are significantly different, unnecessary light is generated at the interface between the daylighting unit 15b and the base material 15a when light enters the base material 15a from the daylighting unit 15b. Refraction or reflection may occur. In this case, there is a possibility that problems such as failure to obtain desired lighting characteristics and a decrease in luminance may occur.
　基材１５ａは、熱可塑性ポリマーや熱硬化性樹脂、光重合性樹脂等の光透過性樹脂からなる。また、光透過性樹脂としては、アクリル系ポリマー、オレフィン系ポリマー、ビニル系ポリマー、セルロース系ポリマー、アミド系ポリマー、フッ素系ポリマー、ウレタン系ポリマー、シリコーン系ポリマー、イミド系ポリマー等からなるものを用いることができる。その中でも、例えば、ポリメタクリル酸メチル樹脂（ＰＭＭＡ）、トリアセチルセルロース（ＴＡＣ）、ポリエチレンテレフタレート（ＰＥＴ）、シクロオレフィンポリマー（ＣＯＰ）、ポリカーボネート（ＰＣ）、ポリエチレンナフタレート（ＰＥＮ）、ポリエーテルサルホン（ＰＥＳ）、ポリイミド（ＰＩ）等を好適に用いることができる。基材１５Ａの全光線透過率は、ＪＩＳ　Ｋ７３６１－１の規定で９０％以上が好ましい。これにより、十分な透明性を得ることができる。 The base material 15a is made of a light transmissive resin such as a thermoplastic polymer, a thermosetting resin, or a photopolymerizable resin. Further, as the light transmissive resin, those made of acrylic polymer, olefin polymer, vinyl polymer, cellulose polymer, amide polymer, fluorine polymer, urethane polymer, silicone polymer, imide polymer, etc. are used. be able to. Among them, for example, polymethyl methacrylate resin (PMMA), triacetyl cellulose (TAC), polyethylene terephthalate (PET), cycloolefin polymer (COP), polycarbonate (PC), polyethylene naphthalate (PEN), polyethersulfone (PES), polyimide (PI), etc. can be used suitably. The total light transmittance of the base material 15A is preferably 90% or more in accordance with JIS K7361-1. Thereby, sufficient transparency can be obtained.
　採光部１５ｂは、例えば、アクリル樹脂やエポキシ樹脂、シリコーン樹脂等の光透過性及び感光性を有する有機材料で構成されている。また、これらの有機材料に、重合開始剤やカップリング剤、モノマー、有機溶媒等を混合したものを用いることができる。さらに、重合開始剤は、安定剤、禁止剤、可塑剤、蛍光増白剤、離型剤、連鎖移動剤、他の光重合性単量体等のように、各種の添加成分を含んでいてもよい。その他、特許第４１２９９９１号公報に記載の材料を用いることができる。採光部２５ｂの全光線透過率は、ＪＩＳ
　Ｋ７３６１－１の規定で９０％以上が好ましい。これにより、十分な透明性を得ることができる。 The daylighting part 15b is comprised with the organic material which has light transmittance and photosensitivity, such as an acrylic resin, an epoxy resin, and a silicone resin, for example. Moreover, what mixed the polymerization initiator, the coupling agent, the monomer, the organic solvent, etc. can be used for these organic materials. Furthermore, the polymerization initiator contains various additive components such as a stabilizer, an inhibitor, a plasticizer, a fluorescent brightening agent, a release agent, a chain transfer agent, and other photopolymerizable monomers. Also good. In addition, materials described in Japanese Patent No. 41299991 can be used. The total light transmittance of the daylighting unit 25b is JIS
90% or more is preferable according to the regulation of K7361-1. Thereby, sufficient transparency can be obtained.
　遮光スラット７は、一方向に長さを有する長尺板状の遮光性基材からなる。遮光性基材は、遮光性を有する生地等によって構成されている。遮光スラット７としては、光を完全に遮光させるものに限られず、例えば、綿、木綿、麻等の透過率の低い材料を用いてもよい。また、遮光性基材として、いわゆるブラインド用のスラットとして一般的に使用されているものを利用してもよく、例えば、アルミニウム等の金属製や木製、樹脂製のものを挙げることができる。また、遮光性基材の表面に塗装等を施したものを挙げることができる。複数の遮光スラット７は、短手方向の一端側が光入射面１１ａを構成する採光機能部１５に接続され、他端側が光射出面１１ｂを構成する光拡散機能部１６に接続されている。 The light shielding slat 7 is made of a long plate-shaped light shielding base material having a length in one direction. The light-shielding substrate is made of a cloth having light-shielding properties. The light shielding slat 7 is not limited to a material that completely shields light, and for example, a material with low transmittance such as cotton, cotton, hemp or the like may be used. Moreover, what is generally used as what is called a blind slat as a light-shielding base material may be utilized, for example, the thing made from metals, such as aluminum, wooden, and resin can be mentioned. Moreover, what coated the surface of the light-shielding base material etc. can be mentioned. The light shielding slats 7 have one end side in the short direction connected to the daylighting function unit 15 constituting the light incident surface 11a and the other end side connected to the light diffusion function unit 16 constituting the light emitting surface 11b.
　光拡散機能部１６は、採光機能部１５を透過するとともに遮光スラット７間を通過した光を、等方的に拡散させる機能を有していてもよいし、光を異方的に拡散させる機能を有していてもよい。等方的光拡散機能を有する光拡散機能部１６として、例えば、透光性フィルムの片面に微細構造を有したフィルム、もしくは透過率の高い（透け感のある）オーガンジー、チュール、シフォン、ジョーゼット、レースなどの生地、一般的なレースカーテンや、シースルーのロールスクリーンに用いられている生地などを使用することが望ましい。また、バインダー樹脂内に多数の拡散ビーズ等が分散された光拡散シート等を用いてもよい。異方的光拡散機能を有する光拡散機能部１６として、例えば、光透過性を有する基材の一面側に、一方向に延在するストライプ状の突起部が延在方向に交差する方向に並ぶ、いわゆる疑似ストライプ構造の異方性光拡散シートを用いてもよい。 The light diffusion function unit 16 may have a function of isotropically diffusing light that has passed through the daylighting function unit 15 and passed between the light shielding slats 7, or a function of anisotropically diffusing light. You may have. As the light diffusing function part 16 having an isotropic light diffusing function, for example, a film having a fine structure on one side of a translucent film, or organdy, tulle, chiffon, georgette having a high transmittance (with a sense of transparency) It is desirable to use fabrics such as lace, general lace curtains, and fabrics used for see-through roll screens. A light diffusion sheet in which a large number of diffusion beads are dispersed in a binder resin may also be used. As the light diffusion function part 16 having an anisotropic light diffusion function, for example, stripe-shaped protrusions extending in one direction are arranged in a direction intersecting the extension direction on one surface side of a light-transmitting substrate. Alternatively, an anisotropic light diffusion sheet having a so-called pseudo stripe structure may be used.
　光拡散機能部１６に入射した光は等方的あるいは異方的に拡散された状態で、光拡散機能部１６を透過する。これにより、窓ガラス１００３に対して入射する太陽光の緯度、方位によって、室内に居る人が感じる眩しさが抑制される。 The light incident on the light diffusion function unit 16 is transmitted through the light diffusion function unit 16 in an isotropically or anisotropically diffused state. Thereby, the glare which the person who exists indoors senses by the latitude and the azimuth | direction of the sunlight which injects with respect to the window glass 1003 is suppressed.
　以上述べた採光装置１０は、図４Ａ，図４Ｂに示すように、採光機能部１５が屋外側、光拡散機能部１６が室内側に向くように設置される。採光装置１０は、光の透過方向に、採光機能部１５、遮光スラット７及び光拡散機能部１６が並んでおり、各々の重なり具合を調整できる構成となっている。 4A and 4B, the daylighting apparatus 10 described above is installed such that the daylighting function unit 15 faces the outdoor side and the light diffusion function unit 16 faces the indoor side. The daylighting device 10 includes a daylighting function unit 15, a light shielding slat 7, and a light diffusion function unit 16 arranged in the light transmission direction, and is configured to be able to adjust the degree of overlap of each.

FIG. 4B is a diagram illustrating a daylighting state of the daylighting screen 11 according to the first embodiment.
FIG. 5 is a diagram illustrating a state in the room where the daylighting apparatus 10 according to the first embodiment is installed, and illustrates a state during light shielding.
　遮光状態の場合、図１に示した操作コード１９を操作して回転軸１８を、採光時とは反対に正転させて、図４Ａに示すように複数の遮光スラット７をその傾斜が垂直に近づくように起立させる。これにより、複数の遮光スラット７が閉じて上下方向で隣り合う遮光スラット７どうしの間の隙間が殆どなくなって、採光スクリーン１１が全閉状態となる。 In the light-shielding state, the operation code 19 shown in FIG. 1 is operated to rotate the rotating shaft 18 in the normal direction opposite to that at the time of daylighting, so that the plurality of light-shielding slats 7 are vertically inclined as shown in FIG. 4A. Stand up to get closer. As a result, the plurality of light shielding slats 7 are closed, and there are almost no gaps between the light shielding slats 7 adjacent in the vertical direction, and the daylighting screen 11 is fully closed.
　この状態で採光装置１０に太陽光が入射すると、光入射面１１ａの採光機能部１５において上方へ屈折された光は、複数の遮光スラット７において遮光されるため、図５に示す室内に太陽光が射出されることはない。 When sunlight enters the daylighting apparatus 10 in this state, the light refracted upward in the daylighting function unit 15 of the light incident surface 11a is blocked by the plurality of light blocking slats 7, so that the sunlight enters the room shown in FIG. Is never ejected.

　図６は、第１実施形態の採光装置１０が設置された室内の様子を示す図であって、採光時の様子を示す図である。
　採光状態の場合、図１に示した操作コード１９を操作して回転軸１８を逆転させて、図４Ｂに示すように複数の遮光スラット７の傾斜が水平に近づくように傾倒させる。各遮光スラット７が太陽光と略平行となり、上下方向で隣り合う遮光スラット７どうしの間に隙間ができて採光スクリーン１１が全開状態となる。 (Lighting state: fully open)
FIG. 6 is a diagram illustrating a state in the room where the daylighting apparatus 10 according to the first embodiment is installed, and illustrates a state during the daylighting.
In the daylighting state, the operation cord 19 shown in FIG. 1 is operated to reverse the rotation shaft 18 so that the plurality of light shielding slats 7 are inclined so that the inclination of the light shielding slats 7 approaches the horizontal as shown in FIG. 4B. Each light shielding slat 7 is substantially parallel to sunlight, and a gap is formed between the light shielding slats 7 adjacent in the vertical direction, so that the daylighting screen 11 is fully opened.
　この状態で採光装置１０に太陽光が入射すると、まず、光入射面１１ａにおける採光機能部１５の各採光部１５ｂにより光が上方に向けて屈折される。採光機能部１５により上方に向けて屈折された光は、鉛直方向に並ぶ遮光スラット７の間を通過して、光拡散機能部１６に入射する。光拡散機能部１６に入射した光は、等方的あるいは異方的に拡散されて、図６に示す光射出面１１ｂから室内の天井１００１側へ向けて射出される。 When sunlight enters the daylighting apparatus 10 in this state, the light is first refracted upward by the daylighting units 15b of the daylighting function unit 15 on the light incident surface 11a. The light refracted upward by the daylighting function unit 15 passes between the light shielding slats 7 arranged in the vertical direction and enters the light diffusion function unit 16. The light that has entered the light diffusion function unit 16 is diffused isotropically or anisotropically and is emitted toward the indoor ceiling 1001 side from the light emission surface 11b shown in FIG.
　また、操作コード１９を操作することにより、採光スクリーン１１の遮光状態と採光状態とを切り替えることができるとともに、遮光状態と採光状態との間の状態を適宜調整することが可能である。太陽光の透過方向において、採光スクリーン１１の採光機能部１５、各遮光スラット７及び光拡散機能部１６の重なり具合を調整することにより、所望の明るさを得ることができる。 Further, by operating the operation code 19, it is possible to switch between the light shielding state and the daylighting state of the daylighting screen 11, and it is possible to appropriately adjust the state between the light shielding state and the daylighting state. In the sunlight transmission direction, desired brightness can be obtained by adjusting the overlapping state of the daylighting function unit 15 of the daylighting screen 11, the light shielding slats 7, and the light diffusion function unit 16.
　図５及び図６では、窓の全面に採光装置１０が設置されているが、これに限られず、一部に設置してもよい。太陽光は窓の上方に入射するため、窓の上部に採光装置１０を設置することが望ましい。 5 and 6, the daylighting apparatus 10 is installed on the entire surface of the window, but the present invention is not limited to this, and it may be installed in a part. Since sunlight is incident on the upper side of the window, it is desirable to install the daylighting device 10 on the upper part of the window.
　本実施形態の採光装置１０では、採光機能部１５から射出された光を光拡散機能部１６において拡散する構成になっているため、グレアを抑えることができる。
　採光装置１０から射出された光は、室内の天井１００１において反射されるため、照明として利用することができる。これによって、省エネ照明を実現することができる。また、採光装置１０により室内に自然光を多く採り入れることで、室内に居ながら太陽光を浴びることができ、セロトニン及びビタミンＤの生成等が促進されて、健康増進にもつながる。 In the daylighting apparatus 10 according to the present embodiment, since the light emitted from the daylighting function unit 15 is configured to diffuse in the light diffusion function unit 16, glare can be suppressed.
Since the light emitted from the daylighting apparatus 10 is reflected on the ceiling 1001 in the room, it can be used as illumination. Thereby, energy-saving lighting can be realized. Moreover, by taking in a lot of natural light indoors by the daylighting apparatus 10, it is possible to be exposed to sunlight while staying indoors, and the production of serotonin and vitamin D is promoted, leading to health promotion.
　窓ガラス１００３に入射した太陽光を採光装置１０において略遮光することが可能である一方で、太陽光の眩しさを抑えつつ室内の明るさを確保したいような場合には、操作コード１９を操作して複数の遮光スラット７の傾斜姿勢を調整することによって、光量の調整が可能である。 When the sunlight entering the window glass 1003 can be substantially shielded by the daylighting apparatus 10, the operation code 19 is operated when it is desired to secure the brightness of the room while suppressing the glare of sunlight. The light quantity can be adjusted by adjusting the inclination postures of the plurality of light shielding slats 7.
　また、本実施形態では、採光機能部１５として、採光フィルム１５Ａの室外側に透過率の高い透過性部材１５Ｂを貼り合わせて一体化されていてもよい。特に、透過性部材１５Ｂとして、例えば、透過率の高い生地を利用することで、採光フィルム１５Ａを構成する樹脂特有の光沢を抑えることができるとともに、採光装置１０の外観のインテリア性を向上させることができる。 Further, in the present embodiment, as the daylighting function unit 15, a transmissive member 15B having a high transmittance may be bonded to the outdoor side of the daylighting film 15A and integrated. In particular, by using, for example, a highly transparent fabric as the transmissive member 15B, the gloss unique to the resin constituting the daylighting film 15A can be suppressed, and the interior of the exterior of the daylighting apparatus 10 can be improved. Can do.
　採光機能部１５及び光拡散機能部１６のそれぞれに用いられる材質によって、採光装置１０の外観の色、柄の選択性が向上する。 Depending on the material used for each of the daylighting function section 15 and the light diffusion function section 16, the color of the appearance of the daylighting apparatus 10 and the selectivity of the pattern are improved.
　また、採光機能部１５と光拡散機能部１６との間に複数の遮光スラット７を配置する構成としたことで、各遮光スラット７上に埃や塵等が溜まるのを防ぐことができる。 In addition, since a plurality of light shielding slats 7 are arranged between the daylighting function unit 15 and the light diffusion function unit 16, it is possible to prevent dust, dust, and the like from accumulating on each light shielding slat 7.
　また、遮光はしたくないが室内のプライバシーを確保したい場合は、採光スクリーン１１を展開した状態（巻き上げられていない状態）で上述した採光状態とすることにより、室内の明るさを確保しつつプライバシーを確保することができる。 If the user wants to ensure indoor privacy but does not want to be shielded from light, the daylighting screen 11 is in the unfolded state (not rolled up) to achieve the above-described daylighting state, thereby ensuring privacy while ensuring indoor brightness. Can be secured.
　また、屋外の眺望性を確保したい場合には、操作コード１９を操作して採光スクリーン１１を上方へ巻き上げることで屋外を眺めることが可能である。採光スクリーン１１の巻上げ具合を調整することで、遮光性と眺望性の両方を確保することができる。 In addition, when it is desired to ensure the outdoor viewability, it is possible to view the outdoors by operating the operation cord 19 and winding up the daylighting screen 11 upward. By adjusting the winding condition of the daylighting screen 11, it is possible to ensure both the light shielding property and the viewability.
　また、遮熱シート等を用いることで遮熱効果が得られ、室内の温度上昇が抑えられる。 Also, by using a heat shield sheet or the like, a heat shield effect can be obtained, and the temperature rise in the room can be suppressed.

　図１０は、第２実施形態の採光装置２０が設置された室内の様子を示す図であって、採光時の様子を示す図である。
　採光状態の場合、図７に示した操作コード１９を操作して、図８Ａに示すように、複数の採光スラット２５をその傾斜が垂直に近づくように起立させる。これにより、複数の採光スラット２５が閉じた状態となり、採光スクリーン２１が全閉状態となる。各採光スラット２５は、一面側が窓ガラス１００３に対向する姿勢となっているため、採光スラット全面で太陽光を受けることができる。 (Lighting state: fully closed)
FIG. 10 is a diagram illustrating a state in the room where the daylighting device 20 of the second embodiment is installed, and illustrates a state during the daylighting.
In the daylighting state, the operation cord 19 shown in FIG. 7 is operated, and as shown in FIG. 8A, the plurality of daylighting slats 25 are erected so that their inclinations approach vertical. As a result, the plurality of daylighting slats 25 are closed, and the daylighting screen 21 is fully closed. Since each daylighting slat 25 has a posture in which one side faces the window glass 1003, it can receive sunlight on the entire surface of the daylighting slat.
　この状態で採光装置２０に太陽光が入射すると、まず、光透過機能部２２を透過し、その後、各採光スラット２５に入射する。採光スラット２５に入射した光は、各採光部２５ｂにより上方に向けて屈折される。採光スラット２５から射出された光は、光拡散機能部１６に入射し、等方的あるいは異方的に拡散されて光射出面１１ｂから、図１０に示す室内の天井１００１へ向けて射出される。 In this state, when sunlight enters the daylighting device 20, the light first passes through the light transmission function unit 22 and then enters each daylighting slat 25. The light incident on the daylighting slats 25 is refracted upward by each daylighting unit 25b. The light emitted from the daylighting slat 25 enters the light diffusion function unit 16, isotropically or anisotropically diffused, and is emitted from the light emission surface 11b toward the indoor ceiling 1001 shown in FIG. .
（透過状態：全開状態）
　図１１は、第２実施形態の採光装置が設置された室内の様子を示す図であって、透過時の様子を示す図である。
　透過状態の場合、図７に示した操作コード１９を操作して、図８Ｂに示すように、複数の採光スラット２５の傾斜が水平に近づくように傾倒させる。各採光スラット２５が太陽光と略平行となり、上下方向で隣り合う採光スラット２５どうしの間に隙間ができて採光スクリーン２１が全開状態となる。 (Transmission state: fully open state)
FIG. 11 is a diagram illustrating a state in the room where the daylighting apparatus according to the second embodiment is installed, and illustrates a state during transmission.
In the transmission state, the operation cord 19 shown in FIG. 7 is operated, and the plurality of daylighting slats 25 are tilted so that the inclination of the plurality of daylighting slats 25 becomes horizontal as shown in FIG. The daylighting slats 25 are substantially parallel to the sunlight, and a gap is formed between the daylighting slats 25 adjacent in the vertical direction, so that the daylighting screen 21 is fully opened.
　この状態で採光装置２０に太陽光が入射すると、光透過機能部２２を透過した光は、上下方向で隣り合う採光スラット２５の間を透過して、光拡散機能部１６に入射する。光拡散機能部１６に入射した光は等方的あるいは異方的に拡散されて、図１１に示す光射出面１１ｂから室内の床１００２へ向けて射出される。 When sunlight enters the daylighting device 20 in this state, the light transmitted through the light transmission function unit 22 passes between the daylighting slats 25 adjacent in the vertical direction and enters the light diffusion function unit 16. The light incident on the light diffusion function unit 16 is diffused isotropically or anisotropically and is emitted toward the indoor floor 1002 from the light emission surface 11b shown in FIG.
　採光装置２０では、操作コード１９を操作することにより、採光スクリーン２１の採光状態と透過状態とを切り替えることができるとともに、光透過機能部２２、各採光スラット２５及び光拡散機能部１６の透過方向での重なり具合を調整することにより、所望の明るさを得ることができる。 In the daylighting device 20, by operating the operation code 19, the daylighting state and the transmission state of the daylighting screen 21 can be switched. The desired brightness can be obtained by adjusting the degree of overlap.
　本実施形態の採光装置２０によれば、採光スラット２５から射出された光を光拡散機能部１６において拡散した後に室内へ射出する構成となっているため、グレアを抑えることができる。採光装置２０から射出され光は、室内の天井１００１において反射されるため、照明として利用することができる。これによって、省エネ照明を実現することができる。また、採光装置２０により、室内に自然光を多く採り入れることで、室内に居ながら太陽光を浴びることができ、セロトニン及びビタミンＤの生成等が促進されて、健康増進にもつながる。 According to the daylighting device 20 of the present embodiment, since the light emitted from the daylighting slat 25 is diffused in the light diffusion function unit 16 and then emitted into the room, glare can be suppressed. Since the light emitted from the daylighting device 20 is reflected by the ceiling 1001 in the room, it can be used as illumination. Thereby, energy-saving lighting can be realized. In addition, the daylighting apparatus 20 allows a large amount of natural light to be taken into the room so that it can be exposed to sunlight while in the room, and the production of serotonin and vitamin D is promoted, leading to health promotion.
　本実施形態の採光装置２０は、遮光機能を有していないため、室内の明るさを常に確保することができる。また、透過状態と採光状態を切り替えることができるとともに、透過状態と採光状態との間で室内に採り入れる光を調光することができるため、窓ガラスだけの場合よりも、室内のプライバシーを確保することができ、眩しさを抑えながら室内の明るさも調整することができる。 Since the daylighting apparatus 20 of the present embodiment does not have a light shielding function, the brightness of the room can always be ensured. In addition, it is possible to switch between the transmissive state and the daylighting state, and it is possible to adjust the light taken into the room between the transmissive state and the daylighting state, thereby ensuring indoor privacy rather than the case of only the window glass. The brightness of the room can be adjusted while suppressing glare.
　また、屋外の眺望性を確保したい場合には、操作コード１９を操作して採光スクリーン２１を上方へ巻き上げることで屋外を眺めることが可能である。採光スクリーン２１の巻上げ具合を調整することで、採光性と眺望性の両方を確保することができる。 In addition, when it is desired to ensure the outdoor viewability, it is possible to view the outdoors by operating the operation cord 19 and winding up the daylighting screen 21 upward. By adjusting the winding condition of the daylighting screen 21, both daylighting and viewability can be ensured.
（変形例）
　図１２は、第２実施形態における採光スクリーンの変形例を示す斜視図である。
　図１２に示すように、光透過機能部２２が、採光スラット２５の長手方向を水平方向に向けて複数の採光スラット２５を鉛直方向に連結する帯状部材２２Ａであってもよい。そのため、採光スクリーン２１Ａの光入射面１１ａ側は開放されている。光透過機能部２２として、例えば、光透過性を有する紐のようなものを採用できる。ここでは、一対の光透過機能部２２，２２が設けられており、複数の採光スラット２５の両端側にそれぞれ１つずつ設けられている。 (Modification)
FIG. 12 is a perspective view showing a modification of the daylighting screen in the second embodiment.
As illustrated in FIG. 12, the light transmission function unit 22 may be a band-shaped member 22 </ b> A that connects the plurality of daylighting slats 25 in the vertical direction with the longitudinal direction of the daylighting slats 25 oriented in the horizontal direction. Therefore, the light incident surface 11a side of the daylighting screen 21A is open. As the light transmission function part 22, a thing like the string which has a light transmittance is employable, for example. Here, a pair of light transmission function portions 22 and 22 are provided, and one light transmission function portion 22 is provided on each of both end sides of the plurality of daylighting slats 25.
　これにより、鉛直方向に並ぶ採光スラット２５の一端側同士、他端側同士を連結することができる。図１２では、一対の光透過機能部２２，２２が採光スラット２５の長手方向に間隔をおいて配置されているが、光透過機能部２２の数や配置間隔は、図示したものに限られない。 Thus, one end side and the other end side of the daylighting slats 25 arranged in the vertical direction can be connected. In FIG. 12, the pair of light transmission function units 22, 22 are arranged at intervals in the longitudinal direction of the daylighting slat 25, but the number and arrangement interval of the light transmission function units 22 are not limited to those illustrated. .
　このような構成によれば、材料にかかる費用を抑えることができるとともに、窓ガラス１００３を透過した太陽光をダイレクトに採光スラット２５へ入射させることができるため、より多くの光を室内へ採り入れることができる。 According to such a configuration, the cost of the material can be suppressed, and the sunlight transmitted through the window glass 1003 can be directly incident on the daylighting slat 25, so that more light can be taken into the room. Can do.

　図１６は、第３実施形態の採光装置３０が設置された室内の様子を示す図であって、透過時の様子を示す図である。
　透過状態の場合、図１３に示した操作コード１９を操作して、図１４Ａ、図１４Ｂに示すように、複数の採光スラット２５及び複数の遮光スラット７の傾斜が水平に近づくように傾倒させる。各採光スラット２５及び各遮光スラット７が太陽光と略平行隣り、上下方向で隣り合う採光スラット２５どうしの間に隙間ができて採光スクリーン２１が全開状態となる。 (Transmission state: fully open state)
FIG. 16 is a diagram illustrating a state in the room where the daylighting device 30 according to the third embodiment is installed, and illustrates a state during transmission.
In the transmissive state, the operation cord 19 shown in FIG. 13 is operated to tilt the plurality of daylighting slats 25 and the plurality of light shielding slats 7 so as to approach the horizontal, as shown in FIGS. 14A and 14B. Each daylighting slat 25 and each light-shielding slat 7 are substantially parallel to sunlight and adjacent to each other in the vertical direction, a gap is formed between the daylighting slats 25, and the daylighting screen 21 is fully opened.
　この状態で採光装置３０に太陽光が入射すると、光透過機能部２２を透過した光は、上下方向で隣り合う採光スラット２５及び遮光スラット７の間を透過して、光拡散機能部１６に入射する。光拡散機能部１６に入射した光は等方的あるいは異方的に拡散されて、図１６に示す光射出面１１ｂから室内の床１００２へ向けて射出される。 When sunlight enters the daylighting device 30 in this state, the light transmitted through the light transmission function unit 22 is transmitted between the daylighting slats 25 and the light shielding slats 7 adjacent in the vertical direction and enters the light diffusion function unit 16.

The light incident on the light diffusion function unit 16 is diffused isotropically or anisotropically and emitted toward the indoor floor 1002 from the light emission surface 11b shown in FIG.
　本実施形態の採光装置３０では、操作コード１９を操作することにより、採光スクリーン３１における上位採光及び下位遮光の状態と、全透過状態と、を適宜切り替えることができる。また、光透過機能部２２、各採光スラット２５及び各遮光スラット７、光拡散機能部１６の透過方向での重なりの具合を適宜調整することにより、所望の明るさを得ることができる。 In the daylighting apparatus 30 of the present embodiment, by operating the operation code 19, it is possible to appropriately switch between the upper lighting and lower light shielding states on the lighting screen 31 and the total transmission state. Moreover, desired brightness can be obtained by appropriately adjusting the degree of overlap in the transmission direction of the light transmission function unit 22, each daylighting slat 25, each light shielding slat 7, and the light diffusion function unit 16.
　本実施形態の採光装置３０によれば、採光スクリーン３１を全閉状態とすることで、採光スクリーン３１の上位に入射した太陽光を採光スラット２５において屈折し、天井へ向けて射出することができるとともに、採光スクリーン３１の下位に入射した太陽光を遮光スラット７において遮光することができる。これにより、室内に居る人に太陽光が直接当たらないようにすることができる。このように、室内に入射する光を抑えつつ、室内に採り入れられた光を照明として利用することができ、室内環境を整えながら省エネ照明を実現することができる。 According to the daylighting device 30 of this embodiment, the sunlight that has entered the upper part of the daylighting screen 31 is refracted by the daylighting slats 25 and can be emitted toward the ceiling by making the daylighting screen 31 fully closed. At the same time, sunlight incident on the lower side of the daylighting screen 31 can be shielded by the light shielding slat 7. Thereby, it is possible to prevent sunlight from directly hitting a person in the room. As described above, the light introduced into the room can be used as illumination while suppressing light incident on the room, and energy-saving illumination can be realized while adjusting the indoor environment.
　また、採光スクリーン３１を全開状態とすることで、室内に自然光を多く採り入れることができ、室内に居ながら太陽光を浴びることが可能である。また、室内に入射する光は、光拡散機能部１６において拡散された状態のため、グレアが抑えられる。 In addition, by making the daylighting screen 31 fully open, a large amount of natural light can be taken into the room, and sunlight can be taken while in the room. Further, since the light incident on the room is diffused in the light diffusion function unit 16, glare is suppressed.

The basic configuration of the daylighting device 40 of the present embodiment described below is substantially the same as that of the first embodiment, but differs in that it has four functions of a daylighting function, a light diffusion function, a light transmission function, and a light blocking function.
Therefore, in the following description, different configurations will be described in detail, and descriptions of common parts will be omitted. In each drawing used for the description, the same reference numerals are given to the same components as those in FIGS.

FIG. 18B is a diagram illustrating a state of upper daylighting and lower order transmission of the daylighting screen 41 of the fourth embodiment.
　本実施形態の採光装置４０は、４つの光学特性が付与された採光スクリーン４１（採光構造体）４１を備えている。図１７及び図１８Ａ，図１８Ｂに示すように、採光スクリーン４１は、光入射面１１ａの上位側に設けられた採光機能部１５と、光射出面１１ｂの下位に設けられた光透過機能部２２と、光射出面１１ｂ側に配置された光拡散機能部１６と、を有している。さらに、採光機能部１５及び光透過機能部２２と、光拡散機能部１６との間に配置された遮光機能部１７を有し、スクリーン全体で４つの光学機能を備えている。
　遮光機能部１７は、複数の遮光スラット（スラット）７を有している。採光機能及び光透過機能を有する光入射面１１ａと、光拡散機能を有する光射出面１１ｂとは、複数の遮光スラット７を介して対向している。 The daylighting device 40 of this embodiment includes a daylighting screen 41 (daylighting structure) 41 to which four optical characteristics are given. As shown in FIGS. 17, 18A, and 18B, the daylighting screen 41 includes a daylighting function unit 15 provided on the upper side of the light incident surface 11a and a light transmission function unit 22 provided on the lower side of the light emission surface 11b. And a light diffusion function unit 16 disposed on the light exit surface 11b side. Furthermore, it has the light-shielding function part 17 arrange | positioned between the daylighting function part 15 and the light transmission function part 22, and the light-diffusion function part 16, and is provided with four optical functions in the whole screen.
The light shielding function unit 17 includes a plurality of light shielding slats (slats) 7. The light incident surface 11 a having a daylighting function and a light transmission function and the light emitting surface 11 b having a light diffusion function are opposed to each other with a plurality of light shielding slats 7 interposed therebetween.
　以上述べた採光装置４０は、図１８Ａ，図１８Ｂに示すように、採光機能部１５及び光透過機能部２２が屋外側、光拡散機能部１６側が室内側に向くように設置される。採光装置４０は、光透過方向に、採光機能部１５及び光透過機能部２２、遮光スラット７、光拡散機能部１６が並んでおり、各々の重なり具合を調整できる構成となっている。本実施形態では、採光スクリーン４１のうち、上位側に採光機能部１５、下位側に光透過機能部２２が設けられているため、採光機能と透過機能との両方を同時に得ることができる。 18A and 18B, the daylighting device 40 described above is installed such that the daylighting function unit 15 and the light transmission function unit 22 face the outdoor side, and the light diffusion function unit 16 side faces the indoor side. The daylighting device 40 is configured such that the daylighting function unit 15, the light transmission function unit 22, the light shielding slat 7, and the light diffusion function unit 16 are arranged in the light transmission direction, and the degree of overlap of each can be adjusted. In the present embodiment, the daylighting screen 41 is provided with the daylighting function unit 15 on the upper side and the light transmission function unit 22 on the lower side, so that both the daylighting function and the transmission function can be obtained simultaneously.
（遮光状態：全閉状態）
　図１９は、第４実施形態の採光装置４０が設置された室内の様子を示す図であって、遮光時の様子を示す図である。
　遮光状態の場合、図１７に示した操作コード１９を操作して、図１８Ａに示すように、複数の遮光スラットの傾斜が垂直に近づくように起立させる。これにより、複数の遮光スラット７が閉じた状態となり、採光スクリーン４１が全閉状態となる。 (Light-shielding state: Fully closed state)
FIG. 19 is a diagram illustrating a state in the room where the daylighting device 40 according to the fourth embodiment is installed, and illustrates a state when light is blocked.
In the light-shielding state, the operation code 19 shown in FIG. 17 is operated, and as shown in FIG. 18A, the plurality of light-shielding slats are erected so as to approach the vertical. Accordingly, the plurality of light shielding slats 7 are closed, and the daylighting screen 41 is fully closed.
　この状態の採光装置４０に太陽光が入射すると、採光機能部１５及び光透過機能部２２に入射した光は、複数の遮光スラット７において遮光されるため、図１９に示す室内に太陽光が射出されることはない。 When sunlight enters the daylighting device 40 in this state, the light incident on the daylighting function unit 15 and the light transmission function unit 22 is shielded by the plurality of light shielding slats 7, so that the sunlight is emitted into the room shown in FIG. It will never be done.
（上位採光及び下位透過の状態：全開状態）
　図２０は、第４実施形態の採光装置４０が設置された室内の様子を示す図であって、上位採光及び下位透過のときの様子を示す図である。
　部分採光状態の場合、操作コード１９を操作して、図１８Ｂに示すように複数の遮光スラット７の傾斜が水平に近づくように傾斜させる。各遮光スラット７が太陽光と略平行となり、上下方向で隣り合う遮光スラット７どうしの間に隙間ができて、採光スクリーン４１が全開状態となる。 (Upper lighting and lower transmission state: fully open)
FIG. 20 is a diagram illustrating a state of the room in which the daylighting device 40 of the fourth embodiment is installed, and is a diagram illustrating a state in the upper daylighting and lower order transmission.
In the partial lighting state, the operation cord 19 is operated to tilt the plurality of light shielding slats 7 so as to approach the horizontal as shown in FIG. 18B. Each light shielding slat 7 is substantially parallel to sunlight, a gap is formed between the light shielding slats 7 adjacent in the vertical direction, and the daylighting screen 41 is fully opened.
　この状態の採光装置４０に入射した太陽光のうち、光入射面１１ａの上位側に入射した光は、採光機能部１５により上方へ向けて屈折される。採光機能部１５において上方へ屈折された光は、鉛直方向に並ぶ遮光スラット７どうし間を通過して、光拡散機能部１６に入射する。光拡散機能部１６に入射した光は、等方的あるいは異方的に拡散されて、図２０に示す光射出面１１ｂから室内の天井１００１へ向けて射出される。 Of the sunlight incident on the daylighting device 40 in this state, the light incident on the upper side of the light incident surface 11a is refracted upward by the daylighting function unit 15. The light refracted upward in the daylighting function unit 15 passes between the light shielding slats 7 arranged in the vertical direction and enters the light diffusion function unit 16. The light incident on the light diffusion function unit 16 is diffused isotropically or anisotropically and is emitted from the light emission surface 11b shown in FIG. 20 toward the indoor ceiling 1001.
　一方、光入射面１１ａの下位側に入射した光は、光透過機能部２２を透過し、鉛直方向に並ぶ遮光スラット７どうしの間を透過して、光拡散機能部１６に入射する。光拡散機能部１６に入射した光は、等方的あるいは異方的に拡散されて、図２０に示す光射出面１１ｂから室内の床１００２へ向けて射出される。 On the other hand, the light incident on the lower side of the light incident surface 11a passes through the light transmission function unit 22, passes through the light shielding slats 7 arranged in the vertical direction, and enters the light diffusion function unit 16. The light that has entered the light diffusion function unit 16 is diffused isotropically or anisotropically and is emitted from the light emission surface 11b shown in FIG. 20 toward the indoor floor 1002.
　本実施形態の採光装置４０では、採光スクリーン４１の上位側において採光した光を室内の天井１００１へ向けて採り入れることができるとともに、採光スクリーン４１の下位側を透過した光を室内の床１００２へ向けて採り入れることができる。室内に入射する光は、光拡散機能部１６において拡散された状態のため、グレアが抑えられる。 In the lighting device 40 of this embodiment, the light collected on the upper side of the daylighting screen 41 can be introduced toward the indoor ceiling 1001, and the light transmitted through the lower side of the daylighting screen 41 is directed to the indoor floor 1002. Can be adopted. Since the light incident on the room is diffused in the light diffusion function unit 16, glare is suppressed.
　本実施形態の採光装置４０では、操作コード１９を操作することにより、採光スクリーン４１の上位採光及び下位透過の状態と、全遮光状態と、を適宜切り替えることができる。また、採光機能部１５及び光透過機能部２２と、遮光スラット７と、光拡散機能部１６の透過方向での重なりの具合を適宜調整することにより、所望の明るさを得ることができる。 In the lighting device 40 of the present embodiment, by operating the operation code 19, it is possible to appropriately switch between the upper lighting and lower transmission states of the lighting screen 41 and the total light blocking state. Moreover, desired brightness can be obtained by appropriately adjusting the overlapping of the daylighting function unit 15 and the light transmission function unit 22, the light shielding slat 7, and the light diffusion function unit 16 in the transmission direction.
　本実施形態の採光装置４０によれば、採光スクリーン４１を全閉状態とすることで、室内に入射する太陽光を遮光することができるとともに、採光スクリーン４１を全開状態とすることで、一部の光を室内照明として利用することができる。これにより、省エネ照明を実現しつつ室内をより明るくすることができるので、快適な室内環境を作り出すことが可能である。 According to the daylighting device 40 of the present embodiment, the daylight incident on the room can be shielded by setting the daylighting screen 41 to the fully closed state, and partly by setting the daylighting screen 41 to the fully open state. Can be used as room lighting. As a result, it is possible to brighten the room while realizing energy-saving lighting, so that a comfortable indoor environment can be created.
　次に、本発明に係る採光装置の一例であるロールスクリーン構造の実施形態についていくつか説明する。 Next, some embodiments of a roll screen structure which is an example of a daylighting apparatus according to the present invention will be described.
［第５実施形態］
　次に、本発明の第５実施形態の採光装置５０について説明する。
　以下に示す本実施形態の採光装置５０の基本構成は上記第１実施形態と略同様であるが、採光機能、光拡散機能、遮光機能の３機能を備えた構成となっている。よって、以下の説明では、異なる構成について詳しく説明し、共通な箇所の説明は省略する。また、説明に用いる各図面において、図１～図６と共通の構成要素には同一の符号を付すものとする。 [Fifth Embodiment]
Next, a daylighting device 50 according to a fifth embodiment of the present invention will be described.
The basic configuration of the daylighting device 50 of the present embodiment shown below is substantially the same as that of the first embodiment, but has a configuration including three functions of a daylighting function, a light diffusion function, and a light blocking function. Therefore, in the following description, different configurations will be described in detail, and descriptions of common parts will be omitted. In each drawing used for the description, the same reference numerals are given to the same components as those in FIGS.
　図２１は、第５実施形態の採光装置５０の全体構成を示す斜視図である。図２２は、第５実施形態の採光装置５０の全体構成を示す側面図である。図２３は、第５実施形態における巻き取り部５３の構成を中心に示す図である。図２４は、第５実施形態における採光ロールスクリーン５１の収納状態を示す図である。 FIG. 21 is a perspective view showing the overall configuration of the daylighting device 50 of the fifth embodiment. FIG. 22 is a side view showing the overall configuration of the daylighting device 50 of the fifth embodiment. FIG. 23 is a diagram mainly showing the configuration of the winding unit 53 in the fifth embodiment. FIG. 24 is a diagram illustrating a storage state of the daylighting roll screen 51 according to the fifth embodiment.
　図２１に示すように、本実施形態の採光装置５０は、環状の採光ロールスクリーン（採光構造体）５１と、採光ロールスクリーン５１を支持する支持機構５２と、を備えて構成されている。 As shown in FIG. 21, the daylighting device 50 of the present embodiment includes an annular daylighting roll screen (daylighting structure) 51 and a support mechanism 52 that supports the daylighting roll screen 51.
　採光ロールスクリーン５１は、周方向に、採光機能領域（第１の光学機能領域）５７、光拡散機能領域（第２の光学機能領域）５８及び遮光機能領域（第３の光学機能領域）５９を有している。これら３つの光学機能領域のうち遮光機能領域５９が採光ロールスクリーン５１の全体に占める割合は、他の光学機能領域がスクリーン全体で占める割合よりも多い。具体的には、採光ロールスクリーン５１の１／２の領域を遮光機能領域５９が占める。残り１／２の領域を採光機能部１５及び光拡散機能部１６が占める。採光機能部１５及び光拡散機能部１６は互いに等しい１：１の割合とされており、スクリーン全体の１／４の領域をそれぞれが占めている。 The daylighting roll screen 51 includes a daylighting function area (first optical function area) 57, a light diffusion function area (second optical function area) 58, and a light shielding function area (third optical function area) 59 in the circumferential direction. Have. Of these three optical function areas, the ratio of the light shielding function area 59 to the entire daylighting roll screen 51 is larger than the ratio of the other optical function areas to the entire screen. Specifically, the light shielding function area 59 occupies a half area of the daylighting roll screen 51. The daylighting function unit 15 and the light diffusion function unit 16 occupy the remaining half of the area. The daylighting function unit 15 and the light diffusing function unit 16 have the same ratio of 1: 1, and each occupies a quarter of the entire screen.
　支持機構５２は、図２１及び図２２に示すように、上下に離間するとともに互いに平行に配置された一対の支持ローラー５２Ａ、５２Ｂと、上位の支持ローラー５２Ａとともに採光ロールスクリーン５１を巻き取り可能な巻き取り部５３と、を有している。一対の支持ローラー５２Ａ，５２Ｂに採光ロールスクリーン５１が巻回されている。 As shown in FIGS. 21 and 22, the support mechanism 52 can wind up the daylighting roll screen 51 together with a pair of support rollers 52 </ b> A and 52 </ b> B that are spaced apart in the vertical direction and arranged in parallel with each other, and the upper support roller 52 </ b> A. And a winding unit 53. A daylighting roll screen 51 is wound around the pair of support rollers 52A and 52B.
　巻き取り部５３は、図２２及び図２３に示すように、一対の支持ローラー５２Ａ，５２Ｂと平行に配置される巻き取り軸５４と、巻き取り軸５４に接続された操作コード５５及びプルコード５６と、巻き取り軸５４に採光ロールスクリーン５１を接続するための接続部４９と、を有している。 As shown in FIGS. 22 and 23, the winding unit 53 includes a winding shaft 54 disposed in parallel with the pair of support rollers 52A and 52B, and an operation cord 55 and a pull cord 56 connected to the winding shaft 54. And a connecting portion 49 for connecting the daylighting roll screen 51 to the winding shaft 54.
　巻き取り軸５４には、図２３に示すように、当該巻き取り軸５４とは個別に回転可能な中心軸５４ａが設けられている。中心軸５４ａには、操作コード５５が接続されているともに、接続部４９を介して採光ロールスクリーン５１が接続されている。中心軸５４ａは、巻き取り軸とは別回転する構成とされ、操作コード５５の操作に伴って中心軸５４ａが回転すると、接続部４９が周方向に送り出されて上位側の支持ローラー５２Ａ及び下位側の支持ローラー５２Ｂが同時に回転する。これら一対の支持ローラー５２Ａ，５２Ｂの回転により、採光ロールスクリーン５１がその周方向へ送り出される。本実施形態においては、下位側の支持ローラー５２Ｂが採光ロールスクリーン５１の送り出しのストッパーとしても機能する。 As shown in FIG. 23, the take-up shaft 54 is provided with a central shaft 54 a that can be rotated separately from the take-up shaft 54. An operation cord 55 is connected to the central shaft 54 a and a daylighting roll screen 51 is connected via a connection portion 49. The central shaft 54a is configured to rotate separately from the winding shaft. When the central shaft 54a rotates in accordance with the operation of the operation cord 55, the connecting portion 49 is sent out in the circumferential direction, and the upper support roller 52A and the lower The side support roller 52B rotates simultaneously. By the rotation of the pair of support rollers 52A and 52B, the daylighting roll screen 51 is sent out in the circumferential direction. In the present embodiment, the lower support roller 52 </ b> B also functions as a feeding stopper for the daylighting roll screen 51.
　本実施形態の巻き取り部５３は、一般的なプリコード式ロールスクリーンの構成と同様の機構であり、巻き取り軸５４にスプリングが内蔵されている。このため、プルコードを引くことにより巻き取り軸５４が回転し、図２４に示すように、図２３に示した上位側の支持ローラー５２Ａとともに採光ロールスクリーン５１が巻き取り軸５４の外周に沿って巻き取られる。 The winding unit 53 of the present embodiment has the same mechanism as that of a general pre-coded roll screen, and a spring is built in the winding shaft 54. For this reason, the take-up shaft 54 rotates by pulling the pull cord, and as shown in FIG. 24, the daylighting roll screen 51 is wound along the outer periphery of the take-up shaft 54 together with the upper support roller 52A shown in FIG. Taken.
　ここで、上位側の支持ローラー５２Ａの直径が、下位側の支持ローラー５２Ｂの直径よりも小さいことが望ましい。これにより、採光ロールスクリーン５１を収納する際に、上位側の支持ローラー５２Ａとともに採光ロールスクリーン５１をスムーズに巻き上げることができる。 Here, it is desirable that the diameter of the upper support roller 52A is smaller than the diameter of the lower support roller 52B. Thereby, when accommodating the daylighting roll screen 51, the daylighting roll screen 51 can be smoothly wound up with the upper support roller 52A.
　以上述べた採光装置５０は、図２５Ａ，図２５Ｂ，図２６Ａ，図２６Ｂに示すように、採光ロールスクリーン５１をその周方向へ回転させることによって、採光機能領域５７、光拡散機能領域５８及び遮光機能領域５９のうち、光の透過方向に並ぶ各領域の重なり具合を調整できる構成となっている。本実施形態では、各領域が採光ロールスクリーン５１の周方向に連続して設けられているため、採光ロールスクリーン５１の回転位置をどの位置で停止させるかによって、光の透過方向に並ぶ各領域の重なり具合を調整でき、室内に入射する光を調光することが可能となっている。 25A, 25B, 26A, and 26B, the daylighting device 50 described above rotates the daylighting roll screen 51 in the circumferential direction thereof, thereby causing the daylighting function area 57, the light diffusion function area 58, and the light shielding function. In the functional area 59, the overlapping state of the areas arranged in the light transmission direction can be adjusted. In the present embodiment, since each region is continuously provided in the circumferential direction of the daylighting roll screen 51, the region of each region arranged in the light transmission direction depends on which position the rotation position of the daylighting roll screen 51 is stopped. The degree of overlap can be adjusted, and light incident on the room can be dimmed.
（上位採光及び下位遮光の状態）
　図２５Ａは、第５実施形態の採光装置５０の全体構成を示す斜視図である。図２５Ｂは、第５実施形態の採光装置５０の全体構成を示す断面図である。
　一部採光、一部遮光の状態では、図２５Ａに示すように、図２１に示した操作コード５５を操作することにより、採光ロールスクリーン５１の上位側において採光機能領域５７の略全面と光拡散機能領域５８の略全面とが光の透過方向で重なるとともに、下位側において遮光機能領域５９の１／２の領域どうしが光の透過方向で互いに重なるように、採光ロールスクリーン５１を回転させる。具体的には、採光ロールスクリーン５１の光入射面５１ａのうち、上位側に採光機能領域５７が位置するとともに下位側に遮光機能領域５９が位置する。一方、光射出面５１ｂのうち、上位側に光拡散機能部１６が位置するとともに下位側に遮光機能領域５９が位置する。 (Upper lighting and lower shading)
FIG. 25A is a perspective view showing the overall configuration of the daylighting device 50 of the fifth embodiment. FIG. 25B is a cross-sectional view showing the overall configuration of the daylighting device 50 of the fifth embodiment.
In the partially-lighted and partially-light-blocked state, as shown in FIG. 25A, by operating the operation code 55 shown in FIG. The daylighting roll screen 51 is rotated so that the substantially entire surface of the functional area 58 overlaps in the light transmission direction and half of the light shielding functional area 59 overlaps in the light transmission direction on the lower side. Specifically, among the light incident surfaces 51a of the daylighting roll screen 51, the daylighting function area 57 is located on the upper side and the light shielding function area 59 is located on the lower side. On the other hand, in the light exit surface 51b, the light diffusion function unit 16 is located on the upper side and the light shielding function region 59 is located on the lower side.
　この状態の採光装置５０に入射した太陽光のうち、採光ロールスクリーン５１の上位側に入射した光は、図２５Ｂに示すように、採光機能領域５７において上方に屈折された後、光拡散機能領域５８において拡散されて、室内の天井へ向けて射出される。一方、採光ロールスクリーン５１の下位側に入射した光は、遮光機能領域５９において遮光される。このため、室内の床へ向かって太陽光が射出されることはない。 Of the sunlight incident on the daylighting device 50 in this state, the light incident on the upper side of the daylighting roll screen 51 is refracted upward in the daylighting function area 57 as shown in FIG. It is diffused at 58 and injected toward the ceiling of the room. On the other hand, the light incident on the lower side of the daylighting roll screen 51 is blocked by the light blocking function area 59. For this reason, sunlight is not emitted toward the indoor floor.
　本実施形態の採光装置５０では、採光ロールスクリーン５１の上位側において採光した光のみを室内へ採り入れることができるとともに、採光ロールスクリーン５１の下位側において太陽光を遮光することができる。 In the daylighting apparatus 50 of this embodiment, only the light collected on the upper side of the daylighting roll screen 51 can be taken into the room, and sunlight can be shielded on the lower side of the daylighting roll screen 51.
（全遮光状態）
　図２６Ａは、第５実施形態の採光装置５０の全体構成を示す斜視図である。図２６Ｂは、第５実施形態の採光装置５０の全体構成を示す断面図である。
　全遮光状態では、図２６Ａに示すように、図２１に示した操作コード５５を操作することにより、採光ロールスクリーン５１の光射出面５１ｂの全体が遮光機能領域５９となるように、採光ロールスクリーン５１を回転させる。光入射面５１ａには、採光機能領域５７及び光拡散機能領域５８が位置する。 (All shaded)
FIG. 26A is a perspective view showing the overall configuration of the daylighting device 50 of the fifth embodiment. FIG. 26B is a cross-sectional view showing the overall configuration of the daylighting device 50 of the fifth embodiment.
In the total light shielding state, as shown in FIG. 26A, the daylighting roll screen is configured so that the entire light exit surface 51b of the daylighting roll screen 51 becomes the light shielding function area 59 by operating the operation code 55 shown in FIG. Rotate 51. The daylighting functional area 57 and the light diffusion functional area 58 are located on the light incident surface 51a.
　この場合、採光ロールスクリーン５１の光入射面５１ａに入射した光は、光拡散機能領域５８及び採光機能領域５７のいずれかを透過した後、遮光機能領域５９において略全て遮光される。このため、室内に太陽光が射出されることはない。 In this case, the light incident on the light incident surface 51 a of the daylighting roll screen 51 passes through either the light diffusion function area 58 or the daylighting function area 57 and is then substantially shielded from light in the light shielding function area 59. For this reason, sunlight is not emitted indoors.
　本実施形態の採光装置５０では、操作コード５５を操作して採光ロールスクリーン５１を回転させることによって、採光ロールスクリーン５１における上位採光及び下位遮光の状態と、全透過状態と、を適宜切り替えることができる。また、採光機能領域５７、光拡散機能領域５８及び遮光機能領域５９の透過方向での重なり具合を適宜調整することにより、所望の明るさを得ることができる。 In the daylighting apparatus 50 of this embodiment, by operating the operation code 55 and rotating the daylighting roll screen 51, the upper daylighting and lower light shielding states in the daylighting roll screen 51 and the total transmission state can be appropriately switched. it can. Moreover, desired brightness can be obtained by appropriately adjusting the overlapping state of the daylighting function area 57, the light diffusion function area 58, and the light shielding function area 59 in the transmission direction.
　本実施形態においては、採光ロールスクリーン５１の全体の１／２の領域が遮光機能領域５９となっているが、１／２以上の領域を占める構成であってもよい。この場合も、採光機能領域５７及び光拡散機能領域５８は、１：１の割合とする。 In the present embodiment, a half area of the entire daylighting roll screen 51 is the light shielding function area 59, but may be configured to occupy a half or more area. Also in this case, the daylighting function area 57 and the light diffusion function area 58 have a ratio of 1: 1.
＜変形例１＞
　次に、第５実施形態の採光装置５０の変形例について説明する。
　図２７Ａ及び図２７Ｂは、第５実施形態の採光装置５０の全体構成を示す図であって、図２７Ａは、部分採光状態を示し、図２７Ｂは全遮光状態を示す。
　図２７Ａに示すように、採光ロールスクリーン５１Ａでは、採光ロールスクリーン５１の全体のうち、遮光機能領域５９が１／２以上３／４以下の領域を占めている。残りの領域に、採光機能領域５７及び光拡散機能領域５８が１：１の割合で存在する。 <Modification 1>
Next, a modification of the daylighting device 50 according to the fifth embodiment will be described.
FIGS. 27A and 27B are diagrams showing the overall configuration of the daylighting device 50 according to the fifth embodiment. FIG. 27A shows a partial daylighting state, and FIG. 27B shows a total light blocking state.
As shown in FIG. 27A, in the daylighting roll screen 51A, the light shielding functional area 59 occupies an area of 1/2 or more and 3/4 or less in the entire daylighting roll screen 51. In the remaining area, the daylighting function area 57 and the light diffusion function area 58 exist at a ratio of 1: 1.
　本実施形態の構成によれば、遮光機能領域５９が占める割合が多いので、室内を遮光したい場合には、採光ロールスクリーン５１Ａを少し回転させるだけで遮光状態へ切り替えることができる。 According to the configuration of the present embodiment, since the light shielding function area 59 occupies a large proportion, when it is desired to shield the room, it is possible to switch to the light shielding state by slightly rotating the daylighting roll screen 51A.
［第６実施形態］
　次に、本発明の第６実施形態の採光装置６０について説明する。
　以下に示す本実施形態の採光装置６０の基本構成は上記第１実施形態と略同様であるが、採光機能、光拡散機能、遮光機能の３機能を備え、光拡散機能を有する領域が他の機能を有する領域よりも大きい点において、先の実施形態と異なる。よって、以下の説明では、異なる構成について詳しく説明し、共通な箇所の説明は省略する。また、説明に用いる各図面において、図２１～図２６Ｂと共通の構成要素には同一の符号を付すものとする。 [Sixth Embodiment]
Next, a daylighting device 60 according to a sixth embodiment of the present invention will be described.
The basic configuration of the daylighting device 60 of the present embodiment shown below is substantially the same as that of the first embodiment, but has three functions of a daylighting function, a light diffusion function, and a light blocking function, and the region having the light diffusion function is the other It differs from the previous embodiment in that it is larger than the area having the function. Therefore, in the following description, different configurations will be described in detail, and descriptions of common parts will be omitted.

　図２８は、第６実施形態の採光装置６０を示す断面図である。
　図２８に示すように、本実施形態の採光装置６０は、採光機能領域５７、光拡散機能領域５８および遮光機能領域５９の３つの光学機能を有する採光ロールスクリーン（採光構造体）６１を備えている。本実施形態の採光ロールスクリーン６１は、採光機能領域５７、光拡散機能領域５８および遮光機能領域５９のうち、光拡散機能領域５８が他の機能を有する領域よりも大きい構成となっている。 FIG. 28 is a cross-sectional view showing the daylighting device 60 of the sixth embodiment.
As shown in FIG. 28, the daylighting device 60 of the present embodiment includes a daylighting roll screen (daylighting structure) 61 having three optical functions: a daylighting function area 57, a light diffusion function area 58, and a light shielding function area 59. Yes. The daylighting roll screen 61 of this embodiment has a configuration in which the light diffusion function region 58 is larger than the region having other functions among the daylighting function region 57, the light diffusion function region 58, and the light shielding function region 59.
　採光ロールスクリーン６１では、光拡散機能領域５８がスクリーン全体の１／２の領域を占めており、残り１／２の領域を採光機能領域５７及び遮光機能領域５９が占める構成となっている。採光機能領域５７及び遮光機能領域５９は互いに等しい１：１の割合とされており、スクリーン全体の１／４の領域をそれぞれが占めている。 In the daylighting roll screen 61, the light diffusion function area 58 occupies a half area of the entire screen, and the daylighting function area 57 and the light shielding function area 59 occupy the remaining half area. The daylighting functional area 57 and the light shielding functional area 59 are set to have an equal ratio of 1: 1, and each occupies a quarter of the entire screen.
（上位遮光及び下位透過の状態）
　図２８に示すように、採光ロールスクリーン６１を回転して窓の上位側に遮光機能領域５９、窓の下位側に光拡散機能領域５８を配置させ、採光ロールスクリーン６１の下側で光拡散機能領域５８の半分の領域どうしが光の透過方向で重なり合う状態にする。 (Upper light shielding and lower transmission state)
As shown in FIG. 28, the daylighting roll screen 61 is rotated to dispose the light shielding function area 59 on the upper side of the window and the light diffusion function area 58 on the lower side of the window. Half of the region 58 is overlapped in the light transmission direction.
　この状態にすることで、窓の上位側から入射する太陽光を遮光するとともに、下位側から入射する光を透過させることができる。この場合、採光ロールスクリーン６１の下位側では光拡散機能領域５８が光の透過方向で重なり合う状態のため、入射する太陽光を透過させる際に拡散し、室内の床を明るく照らすことができる。 In this state, sunlight incident from the upper side of the window can be shielded and light incident from the lower side can be transmitted. In this case, since the light diffusion functional region 58 overlaps in the light transmission direction on the lower side of the daylighting roll screen 61, it diffuses when transmitting the incident sunlight and can brightly illuminate the indoor floor.

FIG. 29 is a cross-sectional view showing the daylighting device 60 of the sixth embodiment, and shows a state of upper daylighting and lower order light shielding.
As shown in FIG. 29, the daylighting roll screen 61 is rotated to arrange the daylighting function area 57 on the upper side of the window and the light shielding function area 59 on the lower side of the window. The diffusion function regions 58 are opposed to each other in the light transmission direction.
　この状態の採光ロールスクリーン６１に入射した太陽光のうち、窓の上位側から入射した光は、採光機能領域５７において上側へ屈折された後、光拡散機能領域５８により拡散された状態で室内の天井へ向けて射出される。また、窓の下位側から入射した光は、遮光機能領域５９において遮られ、室内の床側を日陰にすることができる。
　これにより、室内に居る人が眩しさを感じることなく、外光を室内に採り入れて、天井を明るく照らすことができる。また、室内のプライバシーを確保することもできる。 Of the sunlight incident on the daylighting roll screen 61 in this state, the light incident from the upper side of the window is refracted upward in the daylighting function area 57 and then diffused by the light diffusion function area 58 in the room. It is injected towards the ceiling. Further, light incident from the lower side of the window is blocked by the light blocking function region 59, and the indoor floor side can be shaded.
Thereby, a person in the room can take outside light into the room and illuminate the ceiling without feeling dazzling. Also, indoor privacy can be secured.

FIG. 30 is a cross-sectional view showing the daylighting device 60 of the sixth embodiment, and shows a state of upper transmission and lower light shielding.
As shown in FIG. 30, the daylighting roll screen 61 is rotated so that the light diffusion function area 58 is disposed on the upper side of the window, and the light shielding function area 59 is disposed on the lower side. The two are overlapped in the light transmission direction.
　この状態の採光ロールスクリーン６１に入射した太陽光のうち、窓の上位側から入射した光は、光の透過方向で重なり合う光拡散機能領域５８において拡散された状態で、室内の床へ向けて射出される。また、窓の下位側から入射した光は、採光機能領域５７を透過するものの遮光機能領域５９において遮光される。
　これにより、窓の上位側から光を入射させることができるため、室内のプライバシーを確保しつつ、窓から少し離れた領域を明るく照らすことができる。 Of the sunlight incident on the daylighting roll screen 61 in this state, the light incident from the upper side of the window is emitted toward the indoor floor while being diffused in the light diffusion function region 58 overlapping in the light transmission direction. Is done. Light incident from the lower side of the window passes through the daylighting function area 57 but is shielded in the light shielding function area 59.
Thereby, since light can be incident from the upper side of the window, it is possible to brightly illuminate a region slightly away from the window while ensuring indoor privacy.
（変形例）
　次に、第６実施形態における採光装置６０の変形例について述べる。
　図３１は、採光ロールスクリーン６２の変形例の構成を示す断面図である。

Next, a modification of the daylighting device 60 in the sixth embodiment will be described.
FIG. 31 is a cross-sectional view showing a configuration of a modified example of the daylighting roll screen 62.
In the daylighting roll screen (daylighting structure) 62 shown in FIG. 31, the ratio of the daylighting function area 57, the light diffusion function area 58, and the light shielding function area 59 to the entire daylighting roll screen 62 is different.
　ここでは、採光ロールスクリーン６２の全体で、採光機能領域５７＜遮光機能領域５９＜光拡散機能領域５８の順に占める割合が大きくなっている。具体的に、光拡散機能領域５８はスクリーン全体の１／２の領域を占める。遮光機能領域５９は、スクリーン全体の１／４以上１／２以下の領域を占める。 Here, the ratio of the entire daylighting roll screen 62 in the order of the daylighting function area 57 <light shielding function area 59 <light diffusion function area 58 is increased. Specifically, the light diffusion function area 58 occupies a half area of the entire screen. The light shielding function area 59 occupies an area of 1/4 to 1/2 of the entire screen.
（上位遮光及び下位透過の状態）
　図３１に示すように、採光ロールスクリーン６２を回転して窓の上位側に遮光機能領域５９を配置させるとともに、下位側に光拡散機能領域５８を配置させ、光拡散機能領域５８の一部の領域どうしが光の透過方向で重なり合う状態にする。 (Upper light shielding and lower transmission state)
As shown in FIG. 31, the daylighting roll screen 62 is rotated so that the light shielding function area 59 is disposed on the upper side of the window, and the light diffusion function area 58 is disposed on the lower side, and a part of the light diffusion function area 58 is disposed. The regions are overlapped in the light transmission direction.
　この状態の採光ロールスクリーン６１に入射した太陽光のうち、窓の上位側から入射した光は、遮光機能領域５９において遮光される。窓の下位側から入射した光は、光の透過方向で重なり合う光拡散機能領域５８において拡散されて、室内の床へ向けて射出される。
　これにより、窓の半分以上を遮光したとしても、室内の床が照らされて足元を明るくすることができる。 Of the sunlight incident on the daylighting roll screen 61 in this state, light incident from the upper side of the window is shielded in the light shielding function area 59. Light incident from the lower side of the window is diffused in the light diffusion function region 58 that overlaps in the light transmission direction, and is emitted toward the indoor floor.
Thereby, even if more than half of the window is shielded from light, the floor in the room is illuminated and the feet can be brightened.

FIG. 32 is a cross-sectional view showing a daylighting state of the daylighting roll screen 62.
As shown in FIG. 32, the daylighting roll screen 62 is rotated so that the daylighting function area 57 is arranged on the upper side of the window, and the light shielding function area 59 is arranged on the lower side. In contrast, the light diffusion function region 58 is overlapped in the light transmission direction.
Of the sunlight incident on the daylighting roll screen 62 in this state, the light incident from the upper side of the window is refracted upward in the daylighting functional area 57 and then diffused in the light diffusion functional area 58 to the indoor ceiling. It is injected towards.
Light incident from the lower side of the window is shielded in the light shielding function area 59.
Thereby, a ceiling can be illuminated brightly, ensuring indoor privacy.

FIG. 33 is a cross-sectional view showing a transmission state of the daylighting roll screen 62.
As shown in FIG. 33, the daylighting roll screen 62 is rotated to arrange the light diffusion function area 58 on the upper side of the window, and the daylighting function area 57 is arranged on the lower side. A part of 58 is overlapped in the light transmission direction.
　この状態の採光ロールスクリーン６２に入射した太陽光のうち、窓の上位側から入射した光は、光の透過方向で重なり合う光拡散機能領域５８において拡散された状態で室内へ射出される。窓の中央から下位側に入射した光は光拡散機能領域５８及び採光機能領域５７を透過するものの遮光機能領域５９において遮光される。 Of the sunlight incident on the daylighting roll screen 62 in this state, light incident from the upper side of the window is emitted into the room in a state of being diffused in the light diffusion function region 58 that overlaps in the light transmission direction. Light incident on the lower side from the center of the window passes through the light diffusion functional area 58 and the daylighting functional area 57 but is shielded in the light shielding functional area 59.
　このように、スクリーン全体において、採光機能領域５７よりも遮光機能領域５９が占める割合を多くすることにより、室内のプライバシー性を高めることができる。 Thus, by increasing the ratio of the light shielding function area 59 to the daylighting function area 57 in the entire screen, indoor privacy can be enhanced.
［第７実施形態］
　次に、本発明の第７実施形態の採光装置７０について説明する。
　以下に示す本実施形態の採光装置７０の基本構成は上記第１実施形態と略同様であるが、採光機能、光拡散機能の２機能を備えた点において異なる。よって、以下の説明では、異なる構成について詳しく説明し、共通な箇所の説明は省略する。また、説明に用いる各図面において、図２１～図２６Ｂと共通の構成要素には同一の符号を付すものとする。 [Seventh Embodiment]
Next, a lighting device 70 according to a seventh embodiment of the present invention will be described.
The basic configuration of the daylighting apparatus 70 of the present embodiment shown below is substantially the same as that of the first embodiment, but differs in that it has two functions of a daylighting function and a light diffusion function. Therefore, in the following description, different configurations will be described in detail, and descriptions of common parts will be omitted. In each drawing used for the description, the same reference numerals are given to the same components as those in FIGS. 21 to 26B.
　図３４は、第７実施形態の採光装置７０の全体構成を示す斜視図であって、上位採光及び下位透過の状態を示す。
　図３４に示すように、本実施形態の採光装置７０は、採光機能領域５７及び光拡散機能領域５８の２つの光学機能を有する採光ロールスクリーン（採光構造体）７１を備えている。
　採光ロールスクリーン７１では、光拡散機能領域５８がスクリーン全体の１／２以上の領域を占めており、ここでは３／４の領域を占めている。採光機能領域５７は、残り１／４の領域を占めている。 FIG. 34 is a perspective view showing the overall configuration of the daylighting device 70 of the seventh embodiment, and shows a state of upper daylighting and lower order transmission.
As shown in FIG. 34, the daylighting device 70 of the present embodiment includes a daylighting roll screen (daylighting structure) 71 having two optical functions of a daylighting function area 57 and a light diffusion function area 58.
In the daylighting roll screen 71, the light diffusing functional area 58 occupies an area of ½ or more of the entire screen, and occupies an area of 3/4 here. The daylighting function area 57 occupies the remaining ¼ area.

　図３４に示すように、採光ロールスクリーン７１を回転して窓の上位側に採光機能領域５７、窓の下位側に光拡散機能領域５８を配置させ、採光ロールスクリーン７１の下側で光拡散機能領域５８の一部領域が光の透過方向で重なり合うとともに、上側の採光機能領域５７にも光拡散機能領域５８の一部が光の透過方向で重なり合う状態にする。 (Upper lighting and lower diffusion status)
As shown in FIG. 34, the daylighting roll screen 71 is rotated to arrange the daylighting function area 57 on the upper side of the window and the light diffusion function area 58 on the lower side of the window. A part of the region 58 overlaps in the light transmission direction, and a part of the light diffusion function region 58 also overlaps in the light transmission function region 57 in the light transmission direction.
　この状態の採光ロールスクリーン７１に入射した太陽光のうち、窓の上位側から入射した光は、採光機能領域５７において上側へ屈折された後、光拡散機能領域５８により拡散された状態で室内の天井へ向けて射出される。また、窓の下位側から入射した光は、光の透過方向で重なり合う光拡散機能領域５８において拡散されて室内の床へ向けて射出される。 Of the sunlight incident on the daylighting roll screen 71 in this state, the light incident from the upper side of the window is refracted upward in the daylighting function area 57 and then diffused by the light diffusion function area 58 in the room. It is injected towards the ceiling. In addition, light incident from the lower side of the window is diffused in the light diffusion function region 58 overlapping in the light transmission direction and emitted toward the indoor floor.
　これにより、室内の天井及び床に向けて同時に光が射出されることになるため、採光ロールスクリーン７１を使用しない状態よりも、室内を明るくすることができる。採光ロールスクリーン７１によって室内のプライバシーも確保される。また、室内に居る人の目線に向けて光が射出されることがないため、眩しさを感じることなく快適な室内環境が得られる。 Thereby, since light is simultaneously emitted toward the ceiling and floor of the room, it is possible to make the room brighter than when the daylighting roll screen 71 is not used. Indoor lighting is also ensured by the daylighting roll screen 71. In addition, since no light is emitted toward the eyes of people in the room, a comfortable indoor environment can be obtained without feeling dazzling.

A part of the area 58 is overlapped in the light transmission direction, and a part of the light diffusion function area 58 is overlapped in the light transmission function area 57 in the light transmission direction.
　この状態の採光ロールスクリーン７１に入射した太陽光のうち、窓の上位側から入射した光は、光の透過方向で対向する光拡散機能領域５８において拡散された状態で室内の床へ向けて射出される。窓の下位側から入射した光は、採光機能領域５７において上側へ向けて屈折されて室内の天井へ向けて射出される。室内の中央付近に多くの光が採光されるため、室内に居ながら日光浴をすることができる。 Of the sunlight incident on the daylighting roll screen 71 in this state, light incident from the upper side of the window is emitted toward the indoor floor in a state where it is diffused in the light diffusion function region 58 facing in the light transmission direction. Is done. The light incident from the lower side of the window is refracted upward in the daylighting function area 57 and emitted toward the indoor ceiling. Because much light is collected near the center of the room, you can sunbathe while staying indoors.
　例えば、採光ロールスクリーン７１において室内のプライバシーを確保した状態であっても、太陽光を浴びることができる。これにより、セロトニンやビタミンＤの生成が促進されて健康増進に繋がる。また、窓際に観葉植物等を置いておけば、採光ロールスクリーン７１において室内のプライバシーを確保した状態であっても、観葉植物に直接日光を当てることができる。これにより、寒さに弱い観葉植物を屋外に出すことなく、効果的に日光浴をさせることができる。 For example, even in a state where indoor privacy is secured on the daylighting roll screen 71, it can be exposed to sunlight. Thereby, the production | generation of serotonin and vitamin D is accelerated | stimulated and it leads to health promotion. Further, if a foliage plant or the like is placed near the window, sunlight can be directly applied to the foliage plant even when indoor privacy is ensured on the daylighting roll screen 71. Thereby, it is possible to effectively sunbathe the houseplants that are weak against the cold without taking them outdoors.
　本実施形態においては、光拡散機能領域５８がスクリーン全体の１／２以上の領域を占め、残りの領域を採光機能領域５７が占める構成となっていればよい。
　以下に示す変形例１，２の採光ロールスクリーンでは、全体の１／２の領域以上を光拡散機能領域５８が占め、残りの領域を採光機能領域５７が占める構成となっている。 In the present embodiment, it is sufficient that the light diffusion function area 58 occupies an area of ½ or more of the entire screen and the daylighting function area 57 occupies the remaining area.
In the daylighting roll screens of the following modifications 1 and 2, the light diffusion function area 58 occupies more than half of the entire area, and the daylighting function area 57 occupies the remaining area.
