なお、本実施の形態は、発明の趣旨をより良く理解させるために具体的に説明するものであり、特に指定のない限り、本発明を限定するものではない。
以下、本発明の第1実施形態の採光システムについて説明する。
なお、以下の各図面においては、各構成要素を見やすくするため、構成要素によって寸法の縮尺を異ならせて示すことがある。
図1は、第1実施形態の採光システムの概略構成を示す図である。図2は、第1実施形態の採光システムの概略構成を示す斜視図である。図3Aは、微細構造を光入射側に向けた採光部材と光路を示す図である。図3Bは、微細構造を光射出側に向けた採光部材と光路を示す図である。図3C,図3D,図3Eは、図3Aに光拡散シートを備えた構成を示す図である。図3F,図3G,図3Hは、図3Bに光拡散シートを備えた構成を示す図である。
すなわち、採光システム10の高さH5は、採光装置20の高さH1と遮光装置30の高さH2を足した高さであり、例えば、1.8mである。
光透過性の材料としては、例えば、トリアセチルセルロース(TAC)フィルム、ポリエチレンテレフタレート(PET)フィルム、シクロオレフィンポリマー(COP)フィルム、ポリカーボネート(PC)フィルム、ポリエチレンナフタレート(PEN)フィルム、ポリエーテルサルホン(PES)フィルム、ポリイミド(PI)フィルム等の光透過性のフィルム(基材)が用いられる。
光不透過性の材料としては、例えば、アルミニウム箔、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)等の光透過性の樹脂に顔料を添加して、所定の形状に成形してなるフィルム(基材)等が用いられる。
本実施形態の採光装置20は、図1及び図2に示すように、採光部材21と支持ユニット22とを備えて構成されている。
採光部材21は、上述した採光パネルから構成され、支持ユニット22を介して部屋1002の天井1002aに固定されている。
図3C,図3D,図3Eに、図3Aに光拡散シート27を備えた構成を示す。
図3Cでは、窓ガラス側に採光部42を向けた採光部材21の光射出側に間隔をおいて光拡散シート27が設けられている。図3Dでは、採光部材21の光入射側に間隔をおいて光拡散シート27が設けられている。図3Eでは、採光部材21の光射出側に光拡散シート27が隣接するようにして設けられている。
図3Fでは、室内側に採光部42を向けた採光部材21の光射出側に間隔をおいて光拡散シート27が設けられている。図3Gでは、採光部材21の光入射側に間隔をおいて光拡散シート27が設けられている。図3Hでは、採光部材21の光射出側に光拡散シート27が隣接するようにして設けられている。
光拡散シート27としては、光を主に水平方向(採光部42の長手方向)に拡げるとともに、上下方向(採光部42の短手方向)にはあまり拡げない異方性の光散乱特性が望ましい。光拡散シート27が異方性の光拡散特性を有する場合、室内の左右方向において明るさを均一にすることができる。
光拡散特性を有するものとしては、レンチキュラーレンズ構造、光拡散粒子構造、疑似ストライプ構造等が挙げられる。
調整機構24は、固定具23よりも窓側で採光部材21を支持するものであって、採光部材21と固定具23とを連結する。
このようにして本実施形態の採光システム10が構成されている。
次に、本発明の第2実施形態の採光装置について説明する。
以下に示す本実施形態の採光装置の基本構成は、上記第1実施形態と略同様であるが、採光装置が稼働式(前後移動式)である点において異なる。よって、以下の説明では、第1実施形態と異なる点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3Hと共通の構成要素には同一の符号を付すものとする。
本実施形態の採光システム35は、採光部材を窓ガラス1001に対して進退させる調整機構34を備えている。調整機構34は、一対の延出部24A(一方は不図示)と、採光部材21を支持するとともに延出部24Aに対して水平移動する複数の支持部24Cと、を含んで構成される。
建屋の構造によって採光システム35の設置位置や庇の影響が異なる。このため、建屋の構造に合わせて最適な位置に採光部材21を配置することにより、直射日光が入射する面積が大きくなるように調整することができる。よって、季節や部屋の状況に合わせて、室内に採り入れる採光量を調整することも可能である。
次に、本発明の第3実施形態の採光装置について説明する。
以下に示す本実施形態の採光装置の基本構成は、上記第1実施形態と略同様であるが、採光装置が稼働式(上下移動式)である点において異なる。よって、以下の説明では、第1実施形態と異なる点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3Hと共通の構成要素には同一の符号を付すものとする。
調整機構37は、固定具23から下方に延びる一対の延出部26A(一方は不図示)と、一対の延出部26Aに対して垂直に固定される4本の支持部26Bと、を有している。
一対の延出部26Aは、第1部材26Aaと第2部材26Abとにより構成される上下伸縮構造とされており、一端側が固定具23に固定された第1部材26Aaに対して、第2部材26Abの位置を可変することができる。第2部材26Abには、4本の支持部26を介して採光部材21が設けられている。
これにより、例えば、採光部材21の上位領域が塀の陰になってしまった場合に、採光部材21の位置を下げることによって、上位領域にも太陽光を入射させることが可能になる。このように、天井1002aに対して採光部材21の位置を調整することにより、直射光を受ける面積を調整することができる。よって、季節や一日の太陽高度による微調整も可能となる。
図8は、第3実施形態における調整機構の変形例を示す図である。
図8に示すように、固定具23から延出する一対の延出部26Aに対して、採光部材21を支持する支持部26Bが移動及び固定可能な構成とされた調整機構38としてもよい。調整機構38は、延出部26Aの下端側にストッパー部材(規制手段)39を備えており、当該ストッパー部材39によって、延出部26Aに対する支持部26Bの下方向への移動量(位置)が規制されるようになっている。
次に、本発明の第4実施形態の採光装置について説明する。
以下に示す本実施形態の採光装置の基本構成は、上記第1実施形態と略同様であるが、採光補助シートをさらに備えた点において異なる。よって、以下の説明では、第1実施形態と異なる点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3Hと共通の構成要素には同一の符号を付すものとする。
図9および図10に示すように、本実施形態の採光システム45は、採光部材21よりも室内側に採光補助シート44をさらに備えている。
次に、本発明の第5実施形態の採光装置について説明する。
以下に示す本実施形態の採光装置の基本構成は、上記第1実施形態と略同様であるが、遮光シートをさらに備えた点において異なる。よって、以下の説明では、第1実施形態と異なる点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3Hと共通の構成要素には同一の符号を付すものとする。
図11及び図12に示すように、本実施形態の採光システム46は、光を遮光する遮光部材47をさらに備えている。
遮光部材47は、支持ユニット22に対して回動可能に設けられており、下端側を基点にして上端側が室内へ向かうように回転させることができる。これにより、図11に示す遮光状態から、図12に示す採光状態へと切り替えることが可能となる。遮光部材47は、採光部材21を支持する支持ユニット22に対して着脱自在に設けられる。
上述したいずれの構成においても、調光及び遮光を自在に調整することができる。
次に、本発明の第6実施形態の採光装置について説明する。
以下に示す本実施形態の採光装置の基本構成は、上記第1実施形態と略同様であるが、採光部材の傾きを変化させる機能を備えた点において異なる。よって、以下の説明では、第1実施形態と異なる点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3Hと共通の構成要素には同一の符号を付すものとする。
図13Aは通常の状態を示す図、図13Bは垂直方向に対して傾けた状態を示す図、図13Cは左右方向に対して傾けた状態を示す図である。
図14A,図14Bは、図13Bの構成を具体的に示す図である。
図15A,図15Bは、図13Bの構成を具体的に示す図である。
図16A,図16Bは、図13Cの構成を具体的に示す図である。
図17A,図17Bは、図13Cの構成を具体的に示す図である。
なお、図14A、図15A、図16A、図17Aは斜視図であり、図14B、図15B、図16B、図17Bは側面図である。
次に、本発明の第7実施形態の採光装置について説明する。
以下に示す本実施形態の採光装置の基本構成は、上記第2実施形態と略同様であるが、前後移動式において、採光部材のバランスを調整する機能を備えた点において異なる。よって、以下の説明では、第2実施形態と異なる点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4及び図5と共通の構成要素には同一の符号を付すものとする。
また、重り部53としては、ブラインドの他に、遮光性を有するロールスクリーン、遮光性を有するカーテンなどの遮光部材を用いることができる。
図21は、採光装置および照明調光システムを備えた部屋モデル2000であって、図22のJ-J’線に沿う断面図である。図22は、部屋モデル2000の天井を示す平面図である。
より具体的には、50個の室内照明装置2007が10行(Y方向)×5列(X方向)に配列されている。
