Description
本願は、2013年11月13日に、日本に出願された特願2013-235051号に基づき優先権を主張し、その内容をここに援用する。
図1Aは、本発明の第1実施形態に係る採光フィルム1の概略構成を示す模式的に示す斜視図であり、図1Bは、基材10の概略構成を示す斜視図である。図2は、基材10の概略構成を示す模式的に示す断面図である。図2は、採光フィルムを透過する光の進行方向を説明するための図である。なお、図1A及び図1B、図2において、第1の突起部11を6つ、第2の突起部12を2つしか記載してないが、実際には第1の突起部11及び第2の突起部12が基材10上に多数形成されている。これは他の図面においても同様である。
これにより、十分な透明性を得ることができる。
図2に示すように、採光フィルム1の上方から差し込んだ光のうち第1の突起部11の側面11c1から第1の突起部11の内部に入射した光L0は、第1の突起部11の反射面11c2で全反射され、基材10側から再び採光フィルム1の上方に向けて出射する。
第1の突起部11及び第2の突起部12で反射された光は、屋内の天井や屋内の奥の方まで導かれ、屋内を明るく照らす。
図3に示す採光フィルム101は、基材10上に複数の第1の突起部11及び複数の第2の突起部12が、第1の突起部11及び第2の突起部12の幅方向(Z方向)にひとつずつ交互に配列されている。
このように、基材10上における第2の突起部12の数を増やすことによって、保護基材13との接着性を高めることができる。
図4A,図4Bに示す採光フィルム102,103のように、各第2の突起部12に対応する位置にのみ接着層14を部分的に配置することによって、少ない量の接着材で基材10および保護基材13の貼り合せを行うことが可能である。
図5は、本発明の第2実施形態に係る採光フィルムの概略構成を示す断面図である。
なお、本実施形態において第1実施形態と共通する構成要素については、同じ符号を付し、詳細な説明は省略する。
図6に示す接着フィルム201は、基材10上に、光採光機能を有する第1の突起部11と接着用の突起部22とが、これら第1の突起部11,22の幅方向(Z方向)にひとつずつ交互に配列されている。このように、基材10上における突起部22の数を増やすことによって保護基材13との接着性が高まるので、断面(XZ断面)の形状が三角形とされた突起部22であっても、基材10及び保護基材13同士の良好な貼り合せを実現できる。
図7A,図7Bに示す採光フィルム202,203のように、断面(XZ断面)が三角形とされた各突起部22に対応する位置にのみ、接着層14を部分的に配置してもよい。これによって、少ない量の接着材で基材10及び保護基材13同士の貼り合せを行うことが可能である。
図8は、本発明の第3実施形態に係る採光フィルムの概略構成を示す断面図である。
なお、本実施形態において第1実施形態と共通する構成要素については、同じ符号を付し、詳細な説明は省略する。
このように、第2の突起部12の端面12a及び保護基材13の内面13a同士の間に接着材が流入しても構わないが、これらの間を経て隣り合う第1の突起部11側へと流出することのないよう、充填する接着材の量を調整する。
また、接着層14では光が透過するため採光フィルム30の光透明性が向上する。
図9に示す採光フィルム301は、基材10上に、複数の第1の突起部11と、断面(XZ)の形状が三角形とされた複数の突起部22と、間隔をおいて配置された突起部22同士の間に形成される空隙部15Bに形成される接着層14とを有し、接着層14により、基材10及び保護基材13が貼り合わされた構成となっている。
図10に示す採光フィルム302は、基材10上に、複数の第1の突起部11と、断面(XZ)の形状が台形の第2の突起部12及び断面の形状が三角形の突起部22とを複数備えており、隣り合う第2の突起部12及び突起部22同士の間の接着層14により、基材10および保護基材13が貼り合わされた構成となっている。
このように、空隙部15Cを構成する第2の突起部12及び突起部22同士の形状が互いに異なっていたとしても、相互間に形成される空隙部15Cに形成される接着層14によって、基材10と保護基材13とが直接接着されることになるので、基材同士の貼り合せを強固なものとすることができる。
図11A~図11Cに示す各採光フィルム303,304,305では、隣り合う接着用の突起部同士が隙間なく隣接配置されており、これら突起部同士の間に設けられる接着層14によって、基材10および保護基材13同士が貼り合わされた構成となっている。
この場合も、接着面積を増やすために第2の突起部12の端面12aと保護基材13の内面13aとの間に接着材を配置してもよい。
図12は、本発明の第4実施形態に係る採光フィルムの概略構成を示す斜視図である。
図13は、第4実施形態に係る採光フィルムの平面図である。
なお、本実施形態において第1実施形態と共通する構成要素については、同じ符号を付し、詳細な説明は省略する。
そのため、保護基材13の外面13bから入射した光は、第2の突起部32の側面32c1から第2の突起部32の内部に入射し、反射面32c2で全反射される。
図14は、本発明の第5実施形態に係る採光フィルムの構成を示す断面図である。
なお、本実施形態において第1実施形態と共通する構成要素については、同じ符号を付し、詳細な説明は省略する。
接着層14の厚さを薄くしたとしても、第1の突起部11のみが存在する基材10と保護基材13とを貼り合せたときと同じ接着強度が得られる。
また、本実施形態では、基材10上に第1の突起部11及び第2の突起部42が略等しい数の割合で設けられた構成となっているが、図15に示すように、基材10及び保護基材13同士の間の所要箇所で接着用の第2の突起部42の数を増加しても構わない。例えば、採光フィルム5の側縁において第2の突起部42の数を増やしてもよい。これにより、採光フィルム5の端部からの基材同士の剥がれを防止することができる。
図16A、図16Bに示す採光フィルム501,502のように、第1の突起部11及び第2の突起部42の各々に対応する位置にのみ接着層14を部分的に配置してもよい。これにより、少ない量の接着材で基材10及び保護基材13同士の貼り合せを行うことができる。
図17及び図18は、本発明の第6実施形態に係る採光フィルムの概略構成を示す断面図である。
なお、本実施形態において第1実施形態と共通する構成要素については、同じ符号を付し、詳細な説明は省略する。
図17及び図18に示すように、本実施形態の採光フィルム6は、基材10上に設けられた第1の突起部11及び第2の突起部42のうち、接着用の第2の突起部42のみに対応して設けられた接着層14によって基材10と保護基材13とが貼り合わされた構成となっている。
この構成によれば、第1の突起部11の各々の先端部分が接着層14の中に埋め込まれないので、第1の突起部11の採光性能を維持することができる。
図19は、接着層14による第2の突起部42に対する接着面積の下限についての説明図である。
図19に示すように、空隙部15と接する第2の突起部42の側面(傾斜面)42cの表面積をSaとし、接着層14に埋め込まれる部分の表面積をSbとするとき、Sb≦Sa/2という関係を満たすように、接着層14の厚さを決定する。
なお、先の実施形態の構成においても上記のような関係を満たす。
図20は、本発明の第7実施形態に係る採光フィルムの概略構成を示す斜視図である。
図21は、本実施形態の採光フィルムに係る概略構成を示す断面図である。
なお、本実施形態において第1実施形態と共通する構成要素については、同じ符号を付し、詳細な説明は省略する。
図22に示す採光フィルム701は、基材10上に採光機能を有する断面が三角形の第1の突起部11のみを複数備え、離間して配置された隣り合う第1の突起部11同士の間に設けられた接着層14により、基材10及び保護基材13が貼り合わされた構成となっている。すなわち、基材10上には、複数の突起部群11Aが所定の間隔で設けられ、隣り合う突起部群11A同士の間に形成される空隙部15に接着材を流し込むことによって接着層14が形成される。
このように、採光機能を有する第1の突起部11のみを利用して接着構造を構成してもよい。
図23は、本発明の第8実施形態に係る採光フィルムの構成を示す断面図である。
なお、本実施形態において第1実施形態と共通する構成要素については、同じ符号を付し、詳細な説明は省略する。
図23に示す採光フィルム8は、基材10上に交互に隣接配置された複数の第1の突起部11及び第2の突起部42と、各第2の突起部42の端面42aにそれぞれ配置された複数の遮光部材16とを備え、保護基材13の内面13aに設けられた接着層14によって、基材10及び保護基材13同士が貼り合わされている。
遮光部材16は、第2の突起部42の端面42a全体を覆うようにして設けられ、端面42aと同じ大きさかこれよりも大きく形成されている。
また、図25に示すように、基材10及び保護基材13同士の所要箇所(例えば、採光フィルム8の側縁)に多数設けられた接着用の第2の突起部42に対しても、各々の端面42a側に遮光部材16を設けておく。これにより、グレアが多く発生しやすい領域においても、グレアの発生を防止して採光性を高めることができる。
図26は、本発明の第9実施形態に係る採光フィルムの構成を示す斜視図である。
なお、本実施形態において第1実施形態と共通する構成要素については、同じ符号を付し、詳細な説明は省略する。
なお、接着層14のパターン形状は図示したものに限らない。
図27は、本発明の第10実施形態に係る採光フィルムの構成を示す斜視図である。図28は、採光フィルムの構成を示す断面図である。
なお、本実施形態において第1実施形態と共通する構成要素については、同じ符号を付し、詳細な説明は省略する。
接着材54に含まれるスペーサー54Aとしては、第1の突起部11及び第2の突起部12の高さ、第1の突起部11及び第2の突起部12のピッチよりも大きい値の直径を有した球体が用いられる。これにより、隣り合う第1の突起部11及び第2の突起部12同士の間の隙間にスペーサー54Aが入り込んでしまうのを防ぐことができる。
図30Aに示すように、接着層14と接触する第1の突起部11及び第2の突起部42の先端部分(保護基材13側の端部)に、細かい凹凸18が多数形成されていてもよい。また、図30Bに示すように、第2の突起部42の先端部分に緩やかな曲面を有する凹凸19Aが設けられていてもいいし、複数の曲面からなる凹凸19Bが設けられていてもよい。
このように、接着層14に接触する接着用の第1の突起部11及び第2の突起部42の先端部分に凹凸を設けて形状を荒らすことによって、接着層14に対する接着面積が増えるので、接着強度を高めることができる。
図31は、第11実施形態の採光フィルムの構成を部分的に示す図である。
図31に示すように、基材10上には、複数の突起部形成領域R1は、Z方向及びY方向にそれぞれ所定の間隔をおいて設けられている。各突起部形成領域R1には、複数の第1の突起部11及び複数の第2の突起部12がZ方向に交互に配列されている。隣り合う突起部形成領域R1同士の間の領域は、接着材を介して基材10と保護基材13とを直接接触させる接着領域R2となっており、第1の突起部11及び第2の突起部12が存在していない。
図32は、第12実施形態の採光フィルムの構成を示す図であって、採光フィルムに意匠性を付与した場合の具体例である。
図32に示す採光フィルム40は、基材10上に、複数の第1の突起部11及び複数の第2の突起部12が配列された突起部形成領域R1と、複数の接着領域R2(1)~R2(5)と、このうち接着領域R2(3),R2(4),R2(5)によって周囲を囲まれた突起部形成領域R1(1),R1(2),R1(3)と、を有している。ここでは、複数の接着領域R2(1)~R2(5)によって「SHARP」の文字列が表現されるように構成してある。透明な接着材を用いた場合、接着領域R2(1)~R2(5)には第1の突起部11,12が存在しないため透明性が高く、それ以外の突起部形成領域R1、R1(1)~R1(3)では拡散して見える。このため、採光フィルム40を見た人には、「SHARP」という文字列が浮き出るように視認されることになる。
なお、文字以外にも絵や図柄などを接着領域R2で表現するように構成してもよい。
図33は、第13実施形態の採光フィルムの構成を示す図である。
図33に示す採光フィルム51は、表裏にセパレートフィルム52が積層された構成となっている。
セパレートフィルム52は、基材10の外面10bと保護基材13の外面13bにそれぞれ粘着層17を介して積層されており、基材10の外面10bと、保護基材13の外面13bとをそれぞれ保護するものである。セパレートフィルム52は、ユーザーにより、採光フィルム51を窓ガラス等に貼り付けるまで使用され、貼り付ける直前に、基材10及び保護基材13から剥離されて除かれるものである。
粘着層17は、セパレートフィルム52とともに基材10や保護基材13上から剥離される。これにより、基材10の外面10b及び保護基材13の外面13bが露出する。
図34は、第13実施形態における採光フィルムの製造に用いられる製造装置の一例を示す概略構成図である。
図34に示す製造装置60は、採光フィルム51における基材10の母材となる長尺の基材59をロール・トゥー・ロールで搬送し、その間に各種の処理を行うものである。また、製造装置60は、板状の突起部成形用金型65を用いて第1の突起部11及び第2の突起部12を成形する。
基材59は、第1送出ローラー61側から巻取ローラー62側に向けて移動する構成となっている。
突起部成形用金型65の下方には、基材59を介して照射装置66が配置されている。また、基材59の搬送経路上であって基材59の上方には、第2送出ローラー67A及び接着剤塗布装置68Aが配置されている。さらに、第2送出ローラー67A及び接着剤塗布装置68Aの下方には、基材59を介して第2送出ローラー67B及び接着剤塗布装置68Bがそれぞれ配置されている。
接着剤塗布装置68Bは、第2送出ローラー67Bから送り出されたフィルム基材53の内面53a(基材59の裏面に対向する側の面)に接着剤を塗布するものである。
全光線透過率が90%以上であると、十分な透明性が得られる。
次に、本実施形態における採光フィルムを製造する工程について説明する。ここでは、採光フィルムの形成領域を多数備えた原反ロールの製造工程を中心に、その製造方法について説明する。
図37は、第14実施形態の採光フィルムの構成を示す図である。
図37に示す採光フィルム56は、一面側のみにセパレートフィルム52が積層された構成となっている。具体的には、採光フィルム56の保護基材13の外面13bに、粘着層17を介してセパレートフィルム52が積層されている。
図38は、第14実施形態の採光フィルムの製造に用いられる製造装置の一例を示す概略構成図である。
図38に示す製造装置75は、採光フィルム56における基材10の母材となる長尺の基材59をロール・トゥー・ロールで搬送し、その間に各種の処理を行うものである。また、製造装置75は、円柱状の突起部成形用金型76を用いて第1の突起部11及び第2の突起部12を成形する。
次に、本実施形態における採光フィルムを製造する工程を説明する。ここでは、採光フィルムの形成領域を多数備えた原反ロールの製造工程を中心に、その製造方法について説明する。
製造装置75を用いて採光フィルム56を製造する際には、まず、図38及び図39Aに示すように、第1送出ローラー61から送り出された基材59の一面側に、塗布装置63により感光性樹脂69を所定の膜厚で塗布する。その後、乾燥装置64により、塗布後の感光性樹脂を乾燥させて感光性樹脂層70を形成する。
製造された原反ロール57は、一旦、巻取ローラー62に巻き取られる。その後、巻取ローラー62から巻き出された原反ロール57を、採光フィルム形成領域Rごとに切断することで、図39Dに示すような本実施形態の採光フィルム56を得る。
図40は、第15実施形態の採光フィルムの構成を示す図である。
図40に示す採光フィルム58は、基材10と、接着層25と、採光部81と、接着層14と、保護基材13と、を備えて構成されている。
採光部81は、土台82上に複数の第1の突起部11と複数の第2の突起部12とを有し、接着層25を介して基材10の内面10aに設けられている。本実施形態における採光部81は、土台82により、隣り合う第1の突起部11及び第2の突起部12が基端側において結合した構成とされている。
図41A~図41C、及び、図42A~図42Cは、採光フィルムを個別に製造する工程を示す説明図である。
採光フィルム58を製造するにあたって、図41Aに示すような突起部成形用金型83を用意する。突起部成形用金型83は、上述した突起部成形用金型65と同様に、表面に、第1の突起部11及び第2の突起部12の凹凸パターンと反対の転写パターン83Aが形成されている。
次に、塗布後の感光性樹脂84を乾燥させて塗膜(以下、「感光性樹脂層86」と言う。)を形成する。
次に、図42Cに示すように、基材10の採光部81上に、接着層14を介して保護基材13を貼り合せる。
このようにして、本実施形態の採光フィルム58が完成する。
図43Aは、第16実施形態の採光フィルムの概略構成を示す断面図である。図43Bは、第16実施形態の採光フィルムの概略構成を示す斜視図である。
図43A、図43Bに示すように、採光フィルム80は、基材10上に、複数の第1の突起部11及び第2の突起部12と、を有する採光部87と、接着層14と、保護基材13と、を備える。
採光部87は、土台82の表面82aに複数の第1の突起部11及び第2の突起部12と、を有している。土台82上で隣り合う第1の突起部11と第2の突起部12、第1の突起部11同士は、互いに配列方向で所定の間隔をおいて配置されている。
このように、基材10の一面全体を連続的に覆う土台82の表面82aに、第1の突起部11及び第2の突起部12が間欠的に配置された構成であってもよい。
また、図44Bに示すように、土台82上に、断面形状の異なる第1の突起部11が混在していてもよい。例えば、断面形状が三角形の第1の突起部11の他に、断面形状が四角形の第1の突起部11aや、断面形状が扇状の第1の突起部11bが設けられていてもよい。
図45は、採光装置及び照明調光システムを備えた部屋モデル2000を示す図である。
図46は、部屋モデル2000の天井を示す平面図である。
図47に示すように、採光装置2010(自然光の採光)による机上面の照度は、窓から遠くなる程、低下している。一方で、採光装置2010を窓に設置することなく室内の天井に室内照明装置2007(照明調光システム)を設置した場合には、窓から遠くなる程、机上面の照度が上昇する。これら採光装置2010と室内照明装置2007(照明調光システム)とを併用した場合、採光装置2010及び室内照明装置2007(照明調光システム)のいずれか一方を用いた場合よりも、室内における机上面の照度が全体的に上昇していることが分かる。採光装置2010の効果により窓際が最も明るく、窓から離れるに従って明るさの低下が若干みられるが、略一定の照度(平均照度:750lx)が得られている。
