図1にエレクトロルミネッセンスパネルとして有機ELパネルを用いた本実施形態の送風孔付照明パネル装置1を示す。照明パネルの本体としては面発光体である板状の有機ELパネル2が用いられる。有機ELパネル2には、その表面に形成され内部空間から外部へ貫通する複数の貫通孔4が設けられている。送風孔付照明パネル装置1は、有機ELパネル2を含む隔壁によって内部空間を画定するハウジング5を備えている。送風装置(図示せず)からの空気3が導管6を介してハウジング5へ供給され、この貫通孔4から送風が行われる。有機ELパネル2の貫通孔4以外の外面は発光して照明として用いられる。図1に示すように、貫通孔4に平行に対向してハウジング5の内部空間に、HEPA(high efficiency particulate air)フィルタやULPA(ultra low penetration air)フィルタなどの塵埃エアフィルタFを設けることができる。
以下に、本実施形態による有機ELパネル2の一例を詳述する。図5に示すように、ガラスなどの透明基板20上にて、順に、透明な陽極21(第1電極)、正孔注入層33、正孔輸送層34、発光層35、正孔阻止層36、電子輸送層37、電子注入層38及び金属からなる陰極(第2電極)22が積層されて得られるものが挙げられる。正孔注入層33、正孔輸送層34、発光層35、正孔阻止層36、及び電子輸送層37は有機材料層23である。すなわち、有機EL素子において、対向する1対の陽極及び陰極の間に積層配置された複数の有機材料層が正孔注入層、正孔輸送層、発光層、正孔阻止層、電子輸送層、電子注入層を包含する。これら有機材料層などの構成要素については後述する。このように有機ELパネルの各有機EL素子は、対向する1対の陽極及び陰極の間に積層配置されかつ発光層を含む複数の有機材料層を備えた有機EL素子である。なお、発光層、正孔注入層、正孔輸送層などのいずれの有機材料層は、真空蒸着法など乾式成膜方法やインクジェット法など湿式塗布方法にて成膜され得る。
基板20としては、石英やガラスの板、金属板や金属箔、曲げられる樹脂基板、プラスチックフィルムやシートなどが用いられる。特にガラス板や、ポリエステル、ポリメタクリレート、ポリカーボネート、ポリスルホンなどの透明な合成樹脂の板が好ましい。合成樹脂基板を使用する場合にはガスバリア性に留意する必要がある。基板のガスバリア性が小さすぎると、基板を通過した外気により有機EL素子が劣化することがあるので好ましくない。このため、合成樹脂基板の少なくとも片面に緻密なシリコン酸化膜などを設けてガスバリア性を確保する方法も好ましい方法の一つである。
発光層までの層に正孔を供給する陽極21は、通常、アルミニウム、金、銀、ニッケル、パラジウム、白金などの金属、インジウム及び/又はスズ、亜鉛の酸化物(ITOやIZO)などの金属酸化物、ヨウ化銅などのハロゲン化金属、カーボンブラック、或いは、ポリ(3-メチルチオフェン)、ポリピロール、ポリアニリンなどの導電性高分子などにより構成される。
正孔注入層33、正孔輸送層34、発光層35、電子輸送層36及び電子注入層37の主成分を構成する有機材料層は、電荷輸送性(正孔及び/又は電子の移動性)を有する有機化合物を利用する。
図6は本発明による他の実施形態のファン付照明パネルの照明装置の概略部分切欠斜視図を示す。この照明パネル装置1は、有機ELパネル2を含む隔壁によって内部空間を画定するハウジング5の奥壁側に、有機ELパネル2に対向してファン41を備えている。有機ELパネル2には、上記の実施形態と同様に、その表面に形成され内部空間から外部へ貫通する複数の貫通孔4が設けられている。
図7は本発明による他の実施形態の貫通孔付照明パネルの照明装置の概略部分切欠斜視図を示す。この照明パネル装置1は、有機ELパネル2の発光面の反対側の面に有機ELパネル2の制御回路基板43を設けてある。制御回路基板43としては有機ELパネル調光のために有機ELパネル2をパルス駆動する制御回路基板が挙げられる。内部空間を画定するハウジング(図示せず)としては、上記の実施形態と同様に、図1に示す送風装置からの導管に連通したハウジング5としたり、図6に示すファン付の照明パネルのハウジング5とすることができ、有機ELパネル2の貫通孔4を通して送風が行われる。
図8は本発明による他の実施形態の空気清浄機構付照明パネルの照明装置の平面図を示す。図9は図8中のA-A線の断面図を示す。
上記照明装置においては、エレクトロルミネッセンスパネルとして有機ELパネルを用いた照明装置を例示したが、図1、図6、図7又は図8に示した実施形態の照明装置1、1aにおける有機ELパネル2に代えて無機ELパネルを用いることもできる。本実施形態による無機ELパネル71の一例を図11に示す。無機ELパネル71は、ガラスなどの透明基板20上にて、順に、透過性の第1電極72、誘電体層73、光反射性の第2電極74が積層されて得られるものが挙げられる。誘電体層73には、発光層と絶縁層の交互の積層構造が採用できる。発光層には、SrGa2S4:Eu(緑)、CaS:Eu(赤)、BaAl2S4:Eu(青)などの硫化物、酸化物が用いられ、絶縁層には、チタン酸ストロンチウム(SrTiO3)などの酸化物が用いられる。このように無機ELパネルの各無機EL素子は、基板に担持された、対向する1対の第1及び第2電極の間に発光層を含む複数の無機材料層を備えた素子である。送風用の貫通孔4以外の外面は発光して照明として用いられる。第2電極74側には保護層24が設けられ積層構造となって無機ELパネル71が構成されている。
