Description

本発明は、受光した太陽光を反射させて、該太陽光を建築物の内部や中庭などの所望の位置に導光するための太陽光採光装置及び太陽光採光システムに関する。 The present invention relates to a sunlight lighting device and a sunlight lighting system for reflecting received sunlight and guiding the sunlight to a desired position such as an interior of a building or a courtyard.

この種の太陽光採光装置として、例えば建築物の屋根や屋上などに設置され、受光した太陽光を反射、屈折もしくは透過させつつその光軸方向を変化させて、建築物の居住空間（内部）や中庭などの所望の位置に太陽光を導く太陽光採光装置が知られている。
このような太陽光採光装置では、太陽光を受光して所望の位置に導くための反射鏡やプリズム、レンズなどを備えた採光部を支持する支持軸部が第一駆動機構によって軸線回りに回転することで、採光部の受光面の方位が変化する。また、第二駆動機構の駆動によって採光部が傾動することで、採光部の受光面の傾斜角（仰角）が変化する。そして、第一及び第二駆動機構を随時制御しながら駆動することで、採光部の受光面を、太陽を追尾するように移動させることができ、高度や方位、角度が変化する太陽の光を、確実に受光して下方の建築物の居住空間や中庭などの所望の位置に導光できる（例えば、特許文献１参照）。 This type of solar lighting device is installed on the roof or roof of a building, for example, and changes the optical axis direction while reflecting, refracting or transmitting the received sunlight to change the living space of the building (inside) There is known a solar lighting device that guides sunlight to a desired position such as a garden or a courtyard.
In such a daylighting device, a support shaft portion that supports a daylighting portion including a reflecting mirror, a prism, a lens, and the like for receiving sunlight and guiding it to a desired position is rotated around the axis by a first drive mechanism. As a result, the orientation of the light receiving surface of the daylighting unit changes. Moreover, the tilting angle (elevation angle) of the light receiving surface of the lighting unit is changed by tilting the lighting unit by driving the second drive mechanism. And by driving while controlling the first and second drive mechanisms as needed, the light receiving surface of the daylighting unit can be moved to track the sun, and the light of the sun whose altitude, azimuth, and angle change The light can be reliably received and guided to a desired position such as a living space or a courtyard of the lower building (for example, see Patent Document 1).

しかしながら、従来の太陽光採光装置では以下のような問題があった。
すなわち、上記の太陽光採光装置では、大容量を必要とする場合、１枚の反射鏡やプリズム、レンズなどを備えた採光部の寸法の大きなもの複数台採用することとなる。このように装置の大型化により、設置スペースの確保が困難になるうえ、装置の重量も大きくなるという問題があり、その点で改良の余地があった。 However, the conventional solar lighting device has the following problems.
That is, in the above-described solar lighting device, when a large capacity is required, a plurality of lighting units having a large size of a lighting unit including one reflecting mirror, prism, lens and the like are employed. Thus, the increase in the size of the device makes it difficult to secure the installation space and increases the weight of the device, and there is room for improvement in that respect.

本発明は、上述する問題点に鑑みてなされたもので、簡単な構造で大容量の採光が可能となるうえ、装置の小型化を図ることができる太陽光採光装置を提供することを目的とする。 The present invention has been made in view of the above-described problems, and it is an object of the present invention to provide a solar lighting device that can perform large-capacity daylighting with a simple structure and can reduce the size of the device. To do.

上記目的を達成するため、本発明に係る太陽光採光装置では、受光した太陽光を所望の位置に導くための太陽光採光装置であって、傾動可能な第１反射鏡と第２反射鏡とが２段に重なって配置され、第１反射鏡の第１回動軸と、第２反射鏡の第２回動軸とが異なる方向に向けて配置され、第１反射鏡及び第２反射鏡のいずれか一方を太陽光の入射側に配置した状態で、第１反射鏡の傾斜角度と第２反射鏡の傾斜角度とが太陽の位置に基づいて計算され、第１反射鏡と第２反射鏡とがそれぞれ別々に制御されることを特徴としている。 In order to achieve the above object, the solar light collecting device according to the present invention is a solar light collecting device for guiding received sunlight to a desired position, and is capable of tilting a first reflecting mirror and a second reflecting mirror, Are arranged in two stages, the first rotating shaft of the first reflecting mirror and the second rotating shaft of the second reflecting mirror are arranged in different directions, and the first reflecting mirror and the second reflecting mirror are arranged. In a state where any one of these is arranged on the sunlight incident side, the tilt angle of the first reflecting mirror and the tilt angle of the second reflecting mirror are calculated based on the position of the sun, and the first reflecting mirror and the second reflecting mirror are calculated. The mirror is controlled separately.

また、本発明に係る太陽光採光システムでは、上述した太陽光採光装置を用いた太陽光採光システムであって、複数の太陽光採光装置が採光面方向に連結されていることを特徴としている。 In addition, the solar lighting system according to the present invention is a solar lighting system using the above-described solar lighting device, and is characterized in that a plurality of solar lighting devices are connected in the direction of the lighting surface.

本発明では、太陽光の入射側に設置した一方の反射鏡を太陽の位置に応じて効率的な反射が可能な傾斜角度に制御し、さらにその反射光を受ける他方の反射鏡を前記一方の反射鏡に応じた好適な傾斜角度に制御して、その他方の反射鏡によって反射した反射光を所望の位置に導光することができる。このように、第１反射鏡と第２反射鏡とが２段に分離されそれぞれの傾斜角度を計算して第１反射鏡と第２反射鏡を別々に制御することにより、反射光率を高めることができ、簡単な構造で大容量の採光が可能となる。 In the present invention, one reflecting mirror installed on the sunlight incident side is controlled to an inclination angle that allows efficient reflection according to the position of the sun, and the other reflecting mirror that receives the reflected light is controlled as the one reflecting mirror. The reflected light reflected by the other reflecting mirror can be guided to a desired position by controlling the tilt angle to be suitable for the reflecting mirror. As described above, the first reflecting mirror and the second reflecting mirror are separated in two stages, and the tilt angle is calculated and the first reflecting mirror and the second reflecting mirror are controlled separately, thereby increasing the reflected light rate. Therefore, large-capacity lighting can be achieved with a simple structure.

また、第１反射鏡及び第２反射鏡が長尺板状の形状で、これらを２段に配置させた簡単な構造であり、２段で配置される第１反射鏡と第２反射鏡の幅寸法が太陽光採光装置の厚さ寸法となるので、装置全体を薄くすることができ、小型化を図ることができる。しかも、例えば第１反射鏡と第２反射鏡のそれぞれを並行に配列させて数量を増加させても、その配列方向の面積が大きくなるだけで済み、２段に配置される第１反射鏡及び第２反射鏡のみの厚さ寸法は変わらないので、装置自体の厚さ寸法を増大させずに反射鏡を増やすことができる。 In addition, the first and second reflecting mirrors have a long plate-like shape and are simply arranged in two stages. The first reflecting mirror and the second reflecting mirror are arranged in two stages. Since the width dimension becomes the thickness dimension of the sunlight lighting device, the entire device can be thinned and the size can be reduced. Moreover, for example, even if each of the first reflecting mirror and the second reflecting mirror is arranged in parallel to increase the quantity, it is only necessary to increase the area in the arrangement direction, and the first reflecting mirror arranged in two stages and Since the thickness dimension of only the second reflecting mirror does not change, the number of reflecting mirrors can be increased without increasing the thickness dimension of the apparatus itself.

また、本発明に係る太陽光採光装置では、第１反射鏡と第２反射鏡とは、それぞれ間隔をもって複数並設されていることが好ましい。 Moreover, in the solar light lighting device according to the present invention, it is preferable that a plurality of the first reflecting mirrors and the second reflecting mirrors are arranged in parallel with each other.

本発明では、複数の第１反射鏡を並設した第１反射鏡列群と、複数の第２反射鏡を並設した第２反射鏡列群とが２段に配置された太陽光採光装置を構成することになり、これにより大容量の採光を行うことができる。しかも、上述したように第１反射鏡と第２反射鏡の数量を増やす並設方向が装置の厚さ方向ではないので、装置の厚さ寸法を増大させずに反射鏡の数量を増やすことが可能となる。 In the present invention, a solar light collecting device in which a first reflecting mirror row group in which a plurality of first reflecting mirrors are arranged in parallel and a second reflecting mirror row group in which a plurality of second reflecting mirrors are arranged in parallel are arranged in two stages. Thus, large-capacity lighting can be performed. In addition, as described above, since the juxtaposition direction for increasing the number of the first reflecting mirror and the second reflecting mirror is not the thickness direction of the apparatus, the number of the reflecting mirrors can be increased without increasing the thickness dimension of the apparatus. It becomes possible.

また、本発明に係る太陽光採光装置では、第１回動軸と第２回動軸とが互いに直交していることが好ましい。 Moreover, in the solar light lighting device according to the present invention, it is preferable that the first rotation shaft and the second rotation shaft are orthogonal to each other.

この場合、入射側に設けられる一方の反射鏡の反射面と、導光側に設けられる他方の反射鏡の反射面とが直交する方向に配置されるため、入射側の反射鏡に対して太陽光が斜めに入射して反射した場合であっても、その反射光を導光側の反射鏡で確実に受けることができ、前記反射光のロスが少なくなって採光効率の低下を防ぐことができる。 In this case, the reflecting surface of one reflecting mirror provided on the incident side and the reflecting surface of the other reflecting mirror provided on the light guide side are arranged in a direction orthogonal to the reflecting mirror on the incident side. Even when light is incident obliquely and reflected, the reflected light can be reliably received by the reflecting mirror on the light guide side, and the loss of the reflected light is reduced to prevent the reduction in lighting efficiency. it can.

また、本発明に係る太陽光採光装置では、第１反射鏡及び第２反射鏡は、それぞれ両面に反射板が設けられていることが好ましい。 Moreover, in the sunlight lighting apparatus which concerns on this invention, it is preferable that the 1st reflective mirror and the 2nd reflective mirror are each provided with the reflecting plate on both surfaces.

この場合、入射側の一方の反射鏡の表裏面において移動する太陽光を入射させることができ、また導光側の他方の反射鏡の表裏面で入射側の反射鏡による反射光を入射させることが可能となる。つまり、太陽の位置に合わせて傾動させる第１反射鏡及び第２反射鏡の傾斜角度を小さくすることができるため、反射鏡を複数並設させる場合であっても隣り合う反射鏡同士の間隔を小さく、密にすることができる。したがって、同一の採光面積において反射鏡の数量を増やすことが可能となり、採光効率を向上させることができ、装置の大容量化を図ることができる。 In this case, the moving sunlight can be incident on the front and back surfaces of the one reflecting mirror on the incident side, and the reflected light from the reflecting mirror on the incident side can be incident on the front and back surfaces of the other reflecting mirror on the light guide side. Is possible. In other words, since the tilt angle of the first reflecting mirror and the second reflecting mirror tilted in accordance with the position of the sun can be reduced, even when a plurality of reflecting mirrors are arranged in parallel, the interval between adjacent reflecting mirrors can be reduced. Can be small and dense. Therefore, the number of reflecting mirrors can be increased in the same lighting area, the lighting efficiency can be improved, and the capacity of the apparatus can be increased.

また、本発明に係る太陽光採光装置では、複数の第１反射鏡が第１駆動軸によって連動して所望の傾斜角度に傾動され、複数の第２反射鏡が第２駆動軸によって連動して所望の傾斜角度に傾動されることがより好ましい。 Further, in the sunlight lighting device according to the present invention, the plurality of first reflecting mirrors are tilted to a desired inclination angle in conjunction with the first drive shaft, and the plurality of second reflecting mirrors are interlocked with the second drive shaft. More preferably, it is tilted to a desired tilt angle.

このような構成により、複数の第１反射鏡を連動して同じ傾斜角度に傾動させ、複数の第２反射鏡を連動して同じ傾斜角度に傾動させることで、計算された傾斜角度に精度良く制御することができ、導光する位置のばらつきを防ぐことができ、採光精度を高めることができる。 With such a configuration, the plurality of first reflecting mirrors are interlocked and tilted to the same tilt angle, and the plurality of second reflecting mirrors are interlocked and tilted to the same tilt angle, thereby accurately calculating the calculated tilt angle. It can control, can prevent the variation in the light guide position, and can improve the lighting accuracy.

また、本発明に係る太陽光採光装置では、第１反射鏡及び第２反射鏡は、それぞれの配置枚数が異なっていてもよい。 Moreover, in the solar light lighting device according to the present invention, the first reflecting mirror and the second reflecting mirror may be arranged in different numbers.

この場合、太陽光の反射ロスを少なくして、採光効率を高めるように、入射側に配置される反射鏡と導光側に配置される反射鏡の数量を適宜増減させることができる。 In this case, the number of reflecting mirrors arranged on the incident side and the number of reflecting mirrors arranged on the light guide side can be appropriately increased or decreased so as to reduce the reflection loss of sunlight and increase the lighting efficiency.

また、本発明に係る太陽光採光装置では、第１反射鏡を太陽光の入射側に配置させ、その第１反射鏡で太陽光の東西成分又は南北成分のみを第２反射鏡側に向けて反射させ、その反射光を第２反射鏡で反射させて所定位置に向けて導光させる制御が行われることが好ましい。 Moreover, in the solar light daylighting apparatus according to the present invention, the first reflecting mirror is arranged on the sunlight incident side, and only the east-west component or the north-south component of sunlight is directed to the second reflecting mirror side with the first reflecting mirror. It is preferable to perform control to reflect the light and reflect the reflected light by the second reflecting mirror to guide the light toward a predetermined position.

これにより、入射側に配置した第１反射鏡に入射する太陽光のベクトルを東西方向（又は南北方向）の方向余弦に分解し、東西成分（又は南北成分）の余弦のみを取り出し太陽光採光装置における東西方向（又は南北方向）に反射するように傾斜を算出して第１反射鏡を制御し、第１反射鏡によって反射した東西成分（又は南北成分）の太陽光を第２反射鏡で反射させて所定位置に向けて導光することができる。 Thus, the sunlight vector incident on the first reflecting mirror disposed on the incident side is decomposed into direction cosines in the east-west direction (or north-south direction), and only the cosine of the east-west component (or north-south component) is taken out. The first reflector is controlled by calculating the slope so that it reflects in the east-west direction (or north-south direction), and the east-west component (or north-south component) sunlight reflected by the first reflector is reflected by the second reflector. Thus, light can be guided toward a predetermined position.

本発明の太陽光採光装置及び太陽光採光システムによれば、２段に分離した第１反射鏡と第２反射鏡を重ねて配置する構成であるため、装置の小型化を図ることができる。また、第１反射鏡と第２反射鏡とのそれぞれの好適な傾斜角度を計算して別々に制御することで、反射光率を高めることができることから、簡単な構造で大容量の採光が可能となる効果を奏する。 According to the solar light collecting device and the solar light collecting system of the present invention, since the first reflecting mirror and the second reflecting mirror separated in two stages are arranged in an overlapping manner, the size of the device can be reduced. In addition, it is possible to increase the reflected light rate by calculating and controlling the appropriate tilt angles of the first and second reflecting mirrors separately, so that large-capacity lighting can be achieved with a simple structure. The effect which becomes.

以下、本発明の実施の形態による太陽光採光装置及び太陽光採光システムについて、図面に基づいて説明する。 Hereinafter, a solar light lighting device and a solar light lighting system according to embodiments of the present invention will be described with reference to the drawings.

（第１の実施の形態）
図１に示すように、本第１の実施の形態による太陽光採光装置１Ａは、例えば建築物の屋根や屋上などに設置されて、太陽光Ｓを屋内の所望の位置に採光する際や、本実施の形態のように建物Ｋの屋根部外側に設置されて、建物Ｋに隣接する庭の所望の位置に採光する際に用いられるものである。ここで、図１の符号Ｍは、本実施の形態の太陽光採光装置１Ａによる採光部を示している。また、図１は採光イメージの一例であり、２方向からの大陽光Ｓを示している。
なお、太陽光採光装置１Ａにおける上下方向とは、図１に示す設置状態の場合とする。 (First embodiment)
As shown in FIG. 1, the solar light collecting device 1A according to the first embodiment is installed on, for example, a roof or a roof of a building, and when sunlight S is collected at a desired position indoors. It is installed outside the roof of the building K as in the present embodiment, and is used when lighting at a desired position in the garden adjacent to the building K. Here, the code | symbol M of FIG. 1 has shown the lighting part by 1 A of sunlight lighting apparatuses of this Embodiment. Moreover, FIG. 1 is an example of a daylighting image, and shows the sunlight S from two directions.
In addition, let the vertical direction in 1 A of sunlight lighting apparatuses be the case of the installation state shown in FIG.

図１及び図２に示すように、太陽光採光装置１Ａは、複数のルーバー状の反射鏡（方位鏡２及び仰角鏡３）を上下２段に配列させ、上段に方位角を調整可能な第１回動軸Ｏ１を有する複数の方位鏡２（第１反射鏡）を並設させ、下段に仰角を調整可能な第２回動軸Ｏ２を有する複数の仰角鏡３（第２反射鏡）を並設させた状態で箱状の外殻体４内に収納し、その外殻体４には第１回動軸Ｏ１及び第２回動軸Ｏ２のそれぞれを中心にして方位鏡２及び仰角鏡３を所望の角度に回動（傾動）させる傾動装置５（図６、図７参照）が設けられて概略構成されている。さらに、太陽光採光装置１Ａには、方位鏡２及び仰角鏡３の傾斜角度を太陽の位置に応じて制御する制御部（図示省略）が備えられている。
ここで、太陽光採光装置１Ａにおいて、第２回動軸Ｏ２に平行な方向を装置の東西方向Ｘとし、第１回動軸Ｏ１に平行な方向を装置の南北方向Ｙとする。なお、この東西方向Ｘ及び南北方向Ｙは、太陽光採光装置１Ａにおける見かけ上の方向であって、真の東西南北方向とは異なるものである。 As shown in FIG. 1 and FIG. 2, the solar lighting device 1A has a plurality of louver-like reflecting mirrors (azimuth mirror 2 and elevation mirror 3) arranged in two upper and lower stages, and an azimuth angle that can be adjusted in the upper stage. A plurality of azimuth mirrors 2 (first reflection mirrors) having one rotation axis O1 are juxtaposed, and a plurality of elevation mirrors 3 (second reflection mirrors) having a second rotation axis O2 capable of adjusting the elevation angle at the lower stage. It is housed in a box-like outer shell body 4 in a state of being arranged in parallel, and the outer shell body 4 has an azimuth mirror 2 and an elevation mirror around the first rotation axis O1 and the second rotation axis O2. A tilting device 5 (see FIGS. 6 and 7) for rotating (tilting) 3 to a desired angle is provided and schematically configured. Further, the sunlight lighting device 1A is provided with a control unit (not shown) that controls the inclination angles of the azimuth mirror 2 and the elevation mirror 3 according to the position of the sun.
Here, in the sunlight lighting device 1A, a direction parallel to the second rotation axis O2 is defined as an east-west direction X of the device, and a direction parallel to the first rotation axis O1 is defined as a north-south direction Y of the device. The east-west direction X and the north-south direction Y are apparent directions in the solar lighting device 1A, and are different from the true east-west-north-north direction.

外殻体４は、方位鏡２及び仰角鏡３を上下２段に配置させることが可能な箱形状をなし、上面及び下面が開放された構成、或いはアクリル製やガラス等の透明部材を備えた構成となっている。上面の一端には、傾動装置５や前記制御部に接続されるとともに、それら傾動装置５や制御部に太陽光Ｓより電力を供給するためのソーラーセル６が設けられている。 The outer shell 4 has a box shape in which the azimuth mirror 2 and the elevation mirror 3 can be arranged in two upper and lower stages, and has a configuration in which the upper surface and the lower surface are opened, or a transparent member such as acrylic or glass. It has a configuration. At one end of the upper surface, a solar cell 6 is provided that is connected to the tilting device 5 and the control unit and supplies power from the sunlight S to the tilting device 5 and the control unit.

なお、太陽光採光装置１Ａは、方位鏡２を大陽光Ｓの入射側に向けた状態で、任意の傾き、方位に配置され、太陽光採光装置１Ａの緯度、経度の位置と３軸（Ｘ、Ｙ、Ｚ）の傾きが検出された状態となっている。そして、太陽光採光装置１Ａの検出値（緯度、経度の位置、及び傾き）と太陽の緯度と経度に基づいて、方位鏡角度Ｔ（第１反射鏡の傾斜角度）と仰角鏡角度Ｒ（第２反射鏡の傾斜角度）が前記制御部において計算され、方位鏡２と仰角鏡３との位置が制御され、照射位置（図１の採光部Ｍ）が求められるようになっている。
なお、太陽光採光装置１Ａの緯度、経度については、日本測地系に基づいて位置確認できるが、例えばＧＰＳを用いてその位置を確認するようにしても良い。 The solar lighting device 1A is arranged at an arbitrary inclination and orientation with the azimuth mirror 2 facing the incident side of the solar light S, and the position of the latitude and longitude of the solar lighting device 1A and three axes (X , Y, Z) is detected. Then, based on the detection value (latitude, longitude position and inclination) of the sunlight lighting device 1A and the latitude and longitude of the sun, the azimuth mirror angle T (tilt angle of the first reflector) and the elevation mirror angle R (first) The tilt angle of the two reflecting mirrors) is calculated by the control unit, the positions of the azimuth mirror 2 and the elevation mirror 3 are controlled, and the irradiation position (lighting unit M in FIG. 1) is obtained.
In addition, about the latitude and longitude of 1 A of sunlight lighting apparatuses, although a position can be confirmed based on a Japanese geodetic system, you may make it confirm the position using GPS, for example.

図２乃至図５に示すように、方位鏡２は、第１回動軸Ｏ１を中心にして回転可能に設けられ、一方向（東西方向Ｘ）に向けて一定の間隔Ｄ１をあけて複数配列された方位鏡列群Ｐ１が２列設けられ、太陽の位置に応じて計算された方位鏡角度Ｔに傾動される。
仰角鏡３は、第２回動軸Ｏ２を中心にして回転可能に設けられ、他の一方向（南北方向Ｙ）に向けて一定の間隔Ｄ２をあけて複数配列された仰角鏡列群Ｐ２が２列設けられ、方位鏡角度Ｔに応じて計算された仰角鏡角度Ｒに傾動される。
そして、方位鏡２は、仰角鏡３よりも配置数量が多く密に配置されている。 As shown in FIGS. 2 to 5, the azimuth mirror 2 is provided so as to be rotatable about the first rotation axis O1, and a plurality of azimuth mirrors 2 are arranged at a constant interval D1 in one direction (east-west direction X). Two rows of azimuth mirror rows P1 are provided and tilted to a azimuth mirror angle T calculated according to the position of the sun.
The elevation mirror 3 is provided so as to be rotatable about the second rotation axis O2, and an elevation mirror array group P2 arranged in a plurality at a constant interval D2 in another direction (north-south direction Y) is provided. Two rows are provided and tilted to the elevation mirror angle R calculated according to the azimuth mirror angle T.
The azimuth mirror 2 is arranged more densely and more densely than the elevation mirror 3.

方位鏡２及び仰角鏡３は、それぞれ長尺板状で両面２ａ、２ｂ（３ａ、３ｂ）が反射板をなしており、いずれか一方の面が入射する太陽光Ｓを所望の方向へ向けて反射させるようにして配置されている。つまり、方位鏡２及び仰角鏡３は、太陽の移動に合わせて表裏のいずれか一方の面で太陽光Ｓを入射することができる。 The azimuth mirror 2 and the elevation mirror 3 are each in the form of a long plate, and both surfaces 2a and 2b (3a and 3b) form a reflector, and the sunlight S incident on either surface is directed in a desired direction. It is arranged to reflect. That is, the azimuth mirror 2 and the elevation mirror 3 can make sunlight S incident on one of the front and back surfaces in accordance with the movement of the sun.

方位鏡２は、太陽光Ｓを表面２ａ（又は裏面２ｂ）で反射させる。このとき、太陽光Ｓの位置に応じて好適な方位鏡角度Ｔが計算され、仰角鏡３で入射する照度を最適な値とすることができる。
仰角鏡３は、方位鏡２による第１反射光を表面３ａ（又は裏面３ｂ）で反射させた第２反射光Ｓ’（図１参照）を所定の採光位置（図１に示す採光部Ｍ）へ照射させるものである。このとき、仰角鏡角度Ｒを方位鏡角度Ｔに応じて傾斜させて調整することで、採光部Ｍの照度を最適な値とすることができる。 The azimuth mirror 2 reflects the sunlight S on the front surface 2a (or the back surface 2b). At this time, a suitable azimuth mirror angle T is calculated according to the position of the sunlight S, and the illuminance incident on the elevation mirror 3 can be set to an optimum value.
The elevation mirror 3 has a predetermined lighting position (lighting unit M shown in FIG. 1) of the second reflected light S ′ (see FIG. 1) obtained by reflecting the first reflected light from the azimuth mirror 2 on the front surface 3a (or the back surface 3b). To be irradiated. At this time, the illuminance of the daylighting section M can be set to an optimal value by adjusting the elevation mirror angle R by inclining it according to the azimuth mirror angle T.

上段に設けられる方位鏡列群Ｐ１と下段に設けられる仰角鏡列群Ｐ２は、上下２段に分離された構成となっている。上段の方位鏡２は、第１回動軸Ｏ１が下段の仰角鏡３の第２回動軸Ｏ２に対して直交する方向に向けて配置されている。 The azimuth mirror array group P1 provided in the upper stage and the elevation mirror array group P2 provided in the lower stage are separated into two upper and lower stages. The upper azimuth mirror 2 is arranged in a direction in which the first rotation axis O1 is orthogonal to the second rotation axis O2 of the lower elevation mirror 3.

これら方位鏡列群Ｐ１及び仰角鏡列群Ｐ２は、それぞれ傾動装置５によって連動し、隣り合う方位鏡２、２同士、及び仰角鏡３、３同士が互いに接触しない範囲で適宜、正回転及び逆回転の両方向に傾動する。
また、図３に示すように、上述したように方位鏡２の枚数が仰角鏡３よりも多く設けられており、上段の方位鏡２、２同士の間隔Ｄ１が下段の仰角鏡３、３同士の間隔Ｄ２よりも小さくなっている。 The azimuth mirror array group P1 and the elevation mirror array group P2 are respectively interlocked by the tilting device 5, and are appropriately rotated in the forward and reverse directions as long as the adjacent azimuth mirrors 2, 2 and the elevation mirrors 3, 3 are not in contact with each other. Tilt in both directions of rotation.
As shown in FIG. 3, the number of the azimuth mirrors 2 is larger than that of the elevation mirror 3 as described above, and the distance D1 between the upper azimuth mirrors 2 and 2 is lower than the elevation mirrors 3 and 3. Is smaller than the interval D2.

図６及び図７に示すように、方位鏡２及び仰角鏡３は、上述した図示しない制御部によってそれぞれ所望の方位鏡角度Ｔ、仰角鏡角度Ｒになるように制御され、傾動装置５により動力が伝達され、上段の方位鏡２と下段の仰角鏡３とがそれぞれ別々に連動される構成となっている。ここで、図６及び図７は、方位鏡２（或いは仰角鏡３）の構成を説明するための図であるが、見易くするために主要な方位鏡２のみを示している。 As shown in FIGS. 6 and 7, the azimuth mirror 2 and the elevation mirror 3 are controlled so as to have desired azimuth mirror angle T and elevation mirror angle R, respectively, by the above-described control unit (not shown), and the tilting device 5 provides power. Is transmitted, and the upper azimuth mirror 2 and the lower elevation mirror 3 are separately interlocked. Here, FIGS. 6 and 7 are diagrams for explaining the configuration of the azimuth mirror 2 (or elevation angle mirror 3), but only the main azimuth mirror 2 is shown for easy viewing.

傾動装置５は、第１回動軸Ｏ１に平行に設けられる主軸５１と、主軸５１に回動軸力を付与する駆動モータ３２と、方位鏡２の配列方向に沿って延在するとともに方位鏡２（仰角鏡３）を回動させる一対の駆動軸（第１駆動軸５３、第２駆動軸５４）と、それら第１駆動軸５３、第２駆動軸５４に主軸５１の動力を伝達するためのリンク片５５と、を備えている。 The tilting device 5 extends along the direction of arrangement of the main shaft 51 provided in parallel to the first rotation axis O1, the drive motor 32 that applies a rotation axial force to the main shaft 51, and the direction mirror 2, and the direction mirror 2 (elevation mirror 3) for rotating a pair of drive shafts (first drive shaft 53, second drive shaft 54) and power of the main shaft 51 to the first drive shaft 53 and the second drive shaft 54 Link piece 55.

第１駆動軸５３は、軸方向の一端が主軸５１に支持され、軸方向の所定位置において方位鏡２の第１回動軸Ｏ１に位置する回転中心２ｃに回転可能に支持している。一方、第２駆動軸５４は、リンク片５５を介して主軸５１の動力が直接的に伝達され、方位鏡２の下端２ｄに回転可能に支持している。つまり、第２駆動軸５４は、リンク片５５の回転によって配列方向（第１回動軸Ｏ１に直交する水平方向）に沿って往復動可能となっている。 The first drive shaft 53 is supported at one end in the axial direction by the main shaft 51 and rotatably supported at a rotation center 2c located at the first rotation axis O1 of the azimuth mirror 2 at a predetermined position in the axial direction. On the other hand, the power of the main shaft 51 is directly transmitted to the second drive shaft 54 via the link piece 55, and is rotatably supported on the lower end 2 d of the direction mirror 2. That is, the second drive shaft 54 can reciprocate along the arrangement direction (horizontal direction orthogonal to the first rotation axis O1) by the rotation of the link piece 55.

複数の方位鏡２を連動させて所望の傾斜角度にする際には、駆動モータ５２を駆動させて主軸５１を所定の回転方向に回転させ、各リンク片５５を介して第２駆動軸５４が軸方向に移動させることで、第１駆動軸５３によって回転中心２ｃが固定位置で支持された方位鏡２が傾動する構成となっている。
なお、図６及び図７において、方位鏡２の駆動機構について説明したが、仰角鏡３についても同様であるので、ここでは詳しい説明は省略する。 When a plurality of azimuth mirrors 2 are interlocked to obtain a desired inclination angle, the drive motor 52 is driven to rotate the main shaft 51 in a predetermined rotation direction, and the second drive shaft 54 is moved through each link piece 55. By moving in the axial direction, the azimuth mirror 2 having the rotation center 2c supported at a fixed position by the first drive shaft 53 is tilted.
6 and 7, the driving mechanism of the azimuth mirror 2 has been described. However, since the same applies to the elevation mirror 3, detailed description thereof is omitted here.

上述した制御部（図示省略）は、日時から求められる太陽の緯度及び経度に基づいて方位鏡角度Ｔと仰角鏡角度Ｒを算出し、この算出値（方位鏡角度Ｔと仰角鏡角度Ｒ）に基づいて方位鏡２及び仰角鏡３を制御するように構成されている。 The above-described control unit (not shown) calculates the azimuth mirror angle T and the elevation mirror angle R based on the latitude and longitude of the sun obtained from the date and time, and calculates the calculated values (azimuth mirror angle T and elevation mirror angle R). Based on this, the azimuth mirror 2 and the elevation mirror 3 are controlled.

制御部では、方位鏡２を太陽光Ｓの入射側に配置させ、その反射面（表面２ａ、又は裏面２ｂ）を略東西方向に向けて配置したときに、その方位鏡２で太陽光Ｓの東西成分のみを仰角鏡３側に向けて反射させ、その第１反射光を仰角鏡３で反射させ、その第２反射光Ｓ’を所定位置に向けて導光させる制御が行われるようになっている。 In the control unit, when the azimuth mirror 2 is arranged on the incident side of the sunlight S and the reflection surface (the front surface 2a or the back surface 2b) is arranged substantially in the east-west direction, Only the east-west component is reflected toward the elevation mirror 3, the first reflected light is reflected by the elevation mirror 3, and the second reflected light S ′ is guided toward a predetermined position. ing.

次に、上述した構成からなる太陽光採光装置の制御方法と作用について、図面に基づいて説明する。
図２乃至図５に示すように、上述した太陽光採光装置１Ａでは、太陽光Ｓの入射側に設置した方位鏡２を太陽の位置に応じて効率的な反射が可能な方位鏡角度Ｔに制御し、さらにその第１反射光を受ける仰角鏡３を方位鏡２に応じた好適な仰角鏡角度Ｒに制御して、その仰角鏡３によって反射した第２反射光Ｓ’を所望の位置に導光することができる。このように、方位鏡２と仰角鏡３とが上下２段に分離されそれぞれの方位鏡角度Ｔ、仰角鏡角度Ｒを計算して方位鏡２と仰角鏡３を別々に制御することにより、反射光率を高めることができ、簡単な構造で大容量の採光が可能となる。 Next, the control method and operation of the solar lighting device having the above-described configuration will be described with reference to the drawings.
As shown in FIGS. 2 to 5, in the above-described solar light daylighting apparatus 1 </ b> A, the azimuth mirror 2 installed on the incident side of the sunlight S has an azimuth mirror angle T that allows efficient reflection according to the position of the sun. Further, the elevation mirror 3 that receives the first reflected light is controlled to a suitable elevation mirror angle R corresponding to the azimuth mirror 2, and the second reflected light S ′ reflected by the elevation mirror 3 is brought to a desired position. It can be guided. In this way, the azimuth mirror 2 and the elevation mirror 3 are separated into two upper and lower stages, and the azimuth mirror angle T and elevation mirror angle R are calculated to control the azimuth mirror 2 and elevation mirror 3 separately. The light rate can be increased, and a large volume of light can be obtained with a simple structure.

また、方位鏡２及び仰角鏡３が長尺板状の形状であり、これらを２段に配置させた簡単な構造であり、２段で配置される方位鏡２と仰角鏡３の幅寸法が太陽光採光装置１Ａの厚さ寸法となるので、例えば１０ｃｍ程度に装置全体を薄くすることができ、小型化を図ることができる。しかも、例えば方位鏡２と仰角鏡３のそれぞれを並行に配列させて数量を増加させても、その配列方向の面積が大きくなるだけで済み、上下２段に配置される方位鏡２及び仰角鏡３のみの厚さ寸法は変わらないので、装置自体の厚さ寸法を増大させずに反射鏡を増やすことができる。 Further, the azimuth mirror 2 and the elevation mirror 3 have a long plate shape, and have a simple structure in which these are arranged in two stages. The width dimensions of the azimuth mirror 2 and the elevation mirror 3 arranged in two stages are as follows. Since it becomes the thickness dimension of 1 A of sunlight lighting apparatuses, the whole apparatus can be made thin about 10 cm, for example, and size reduction can be achieved. In addition, for example, even if the azimuth mirror 2 and the elevation mirror 3 are arranged in parallel to increase the quantity, only the area in the arrangement direction needs to be increased, and the azimuth mirror 2 and the elevation mirror arranged in two upper and lower stages. Since the thickness dimension of only 3 does not change, the number of reflecting mirrors can be increased without increasing the thickness dimension of the apparatus itself.

また、方位鏡２と仰角鏡３とは、それぞれ間隔をもって複数並設されており、複数の方位鏡２を並設した方位鏡列群Ｐ１と、複数の仰角鏡３を並設した仰角鏡列群Ｐ２とが２段に配置された太陽光採光装置１Ａを構成することになり、これにより大容量の採光を行うことができる。しかも、上述したように方位鏡２と仰角鏡３の数量を増やす並設方向が装置の厚さ方向ではないので、装置の厚さ寸法を増大させずに方位鏡２及び仰角鏡３の数量を増やすことが可能となる。 A plurality of azimuth mirrors 2 and elevation mirrors 3 are arranged in parallel with each other, and an azimuth mirror row group P1 in which a plurality of azimuth mirrors 2 are arranged in parallel, and an elevation mirror row in which a plurality of elevation mirrors 3 are arranged in parallel. The solar lighting device 1A in which the group P2 and the group P2 are arranged in two stages is configured, and thereby large-capacity lighting can be performed. Moreover, as described above, the parallel direction for increasing the quantity of the azimuth mirror 2 and the elevation mirror 3 is not the thickness direction of the apparatus, so the quantity of the azimuth mirror 2 and the elevation mirror 3 can be reduced without increasing the thickness dimension of the apparatus. It becomes possible to increase.

また、方位鏡２の第１回動軸Ｏ１と仰角鏡３の第２回動軸Ｏ２とが互いに直交しており、方位鏡２の反射面と、仰角鏡３の反射面とが直交する方向に配置されるため、方位鏡２に対して太陽光Ｓが斜めに入射して反射した場合であっても、その第１反射光を仰角鏡３で確実に受けることができ、前記反射光のロスが少なくなって採光効率の低下を防ぐことができる。 Further, the first rotation axis O1 of the azimuth mirror 2 and the second rotation axis O2 of the elevation mirror 3 are orthogonal to each other, and the reflection surface of the azimuth mirror 2 and the reflection surface of the elevation mirror 3 are orthogonal to each other. Therefore, even when the sunlight S is incident obliquely on the azimuth mirror 2 and reflected, the first reflected light can be reliably received by the elevation mirror 3, and the reflected light Loss is reduced, and a reduction in lighting efficiency can be prevented.

さらに、方位鏡２及び仰角鏡３は、それぞれ両面に反射板が設けられているので、方位鏡２の表面１０ａ、裏面１０ｂにおいて移動する太陽光を入射させることができ、また仰角鏡３の表面２０ａ、裏面２０ｂで方位鏡２による第１反射光を入射させることが可能となる。つまり、太陽の位置に合わせて傾動させる方位鏡２及び仰角鏡３のそれぞれの傾斜角度（方位鏡角度Ｔ、仰角鏡角度Ｒ）を小さくすることができるため、方位鏡２及び仰角鏡３を複数並設させる場合であっても隣り合う反射鏡同士の間隔を小さく、密にすることができる。したがって、同一の採光面積において方位鏡２及び仰角鏡３の数量を増やすことが可能となり、採光効率を向上させることができ、装置の大容量化を図ることができる。 Furthermore, since the azimuth mirror 2 and the elevation mirror 3 are provided with reflecting plates on both surfaces, respectively, sunlight moving on the front surface 10a and the back surface 10b of the azimuth mirror 2 can be made incident. It becomes possible to make the 1st reflected light by the azimuth | direction mirror 2 inject into 20a and the back surface 20b. That is, since the tilt angles (azimuth mirror angle T and elevation mirror angle R) of the azimuth mirror 2 and the elevation mirror 3 tilted according to the position of the sun can be reduced, a plurality of the azimuth mirrors 2 and elevation mirrors 3 are provided. Even when juxtaposed, the spacing between adjacent reflecting mirrors can be made small and dense. Therefore, it is possible to increase the quantity of the azimuth mirror 2 and the elevation mirror 3 in the same daylighting area, improve the daylighting efficiency, and increase the capacity of the apparatus.

また、第１駆動軸３３Ａによって複数の方位鏡２を連動して同じ傾斜角度に傾動させ、第２駆動軸３３Ｂによって複数の仰角鏡３を連動して同じ傾斜角度に傾動させることで、計算された傾斜角度に精度良く制御することができ、導光する位置のばらつきを防ぐことができ、採光精度を高めることができる。 In addition, the plurality of azimuth mirrors 2 are interlocked and tilted to the same tilt angle by the first drive shaft 33A, and the plurality of elevation mirrors 3 are interlocked and tilted to the same tilt angle by the second drive shaft 33B. Therefore, it is possible to accurately control the tilt angle, to prevent variations in the light guide position, and to improve the daylighting accuracy.

また、入射側に配置される方位鏡２を導光側に配置される仰角鏡３の数量よりも多くすることで、太陽光の反射ロスを少なくして、採光効率を高めることができる。 Further, by increasing the number of azimuth mirrors 2 arranged on the incident side than the number of elevation mirrors 3 arranged on the light guide side, it is possible to reduce the reflection loss of sunlight and increase the lighting efficiency.

さらにまた、制御部における、太陽の軌道に応じて算出される方位鏡角度Ｔと仰角鏡角度Ｒの計算方法では、方位鏡２と仰角鏡３とを別々に制御する。具体的には、先ず方位鏡角度Ｔを算出する第１ステップと、仰角鏡角度Ｒを算出する第２ステップとが行われる。すなわち、第１ステップでは、方位鏡２に入射する太陽光Ｓのベクトルを東西方向の方向余弦に分解し、東西成分の余弦のみを取り出し太陽光採光装置１Ａにおける東西方向Ｘに反射するように傾斜を算出して方位鏡２を制御する。第２ステップでは、方位鏡２によって反射した東西成分Ｘの太陽光Ｓを仰角鏡３で反射させた第２反射光Ｓ’を所定位置に向けて導光することができる。 Furthermore, in the calculation method of the azimuth mirror angle T and the elevation mirror angle R calculated according to the orbit of the sun in the control unit, the azimuth mirror 2 and the elevation mirror 3 are controlled separately. Specifically, first, a first step for calculating the azimuth mirror angle T and a second step for calculating the elevation angle R are performed. That is, in the first step, the vector of the sunlight S incident on the azimuth mirror 2 is decomposed into directional cosines in the east-west direction, and only the cosine of the east-west component is extracted and tilted so as to be reflected in the east-west direction X in the solar lighting device 1A. Is calculated and the azimuth mirror 2 is controlled. In the second step, the second reflected light S ′ obtained by reflecting the sunlight S of the east-west component X reflected by the azimuth mirror 2 with the elevation mirror 3 can be guided toward a predetermined position.

上述のように本実施の形態による太陽光採光装置及び太陽光採光システムでは、２段に分離した方位鏡２と仰角鏡３を重ねて配置する構成であるため、装置の小型化を図ることができる。
また、方位鏡２と仰角鏡３とのそれぞれの好適な傾斜角度（方位鏡角度Ｔ、仰角鏡角度Ｒ）を計算して別々に制御することで、反射光率を高めることができることから、簡単な構造で大容量の採光が可能となる効果を奏する。 As described above, the solar lighting device and the solar lighting system according to the present embodiment have a configuration in which the azimuth mirror 2 and the elevation mirror 3 separated in two stages are arranged to overlap each other, so that the size of the device can be reduced. it can.
In addition, since the preferred tilt angles (azimuth mirror angle T and elevation mirror angle R) of the azimuth mirror 2 and the elevation mirror 3 are calculated and controlled separately, the reflected light rate can be increased. With such a structure, it is possible to obtain a large amount of daylighting.

次に、本発明の太陽光採光装置及び太陽光採光システムによる他の実施の形態について、添付図面に基づいて説明するが、上述の第１の実施の形態と同一又は同様な部材、部分には同一の符号を用いて説明を省略し、第１の実施の形態と異なる構成について説明する。 Next, other embodiments of the solar lighting device and the solar lighting system of the present invention will be described with reference to the accompanying drawings, but the same or similar members and parts as those of the first embodiment described above are included.
