Description

【０００１】
【発明の属する技術分野】
本発明は、照明器具を引っ掛けシーリングに取付けるための照明器具の取付け装置及びこれを備えた照明装置に関するものである。
【０００２】
【従来の技術】
照明器具を引っ掛けシーリングに取付けるための照明器具の取付け装置としては、例えば、実開平５ー９０７２６号公報が知られいる。この実開平５ー９０７２６号公報に示される従来例は、図１５に示すように、取付け装置Ａ′が、取付け装置Ａ′の主体を構成する本体部１′の上面に引っ掛けシーリング２に係止自在とする係止爪を設け、この本体部１′の外周面部に係止部７′を横方向に移動自在で且つ本体部１′の外周面部から出没自在に設け、更に、本体部１′に係止部７′を引き込ませるための操作を行う上下方向に移動自在な操作釦５０を設けて構成してある。そして、天井４４に取付けた引っ掛けシーリング２に取付け装置Ａ′に設けた係止爪を引っ掛け係止し、この状態で、取付け装置Ａ′の本体部１′に照明器具本体４の挿入孔５を被嵌すると共に、照明器具本体４の係合部６′に本体部１′より突出した係止部７′を係止するようにしている。また、従来例にあっては、電気的接続手段５３を本体部１′の外周面部に設けていた。
【０００３】
一方、照明器具本体４を取り外すに当たっては、操作釦５０を上方に押して、係止部７′を係合部６′から抜き、その後、照明器具本体４を下方に引き下ろすことにより取り外すようにしていた。
【０００４】
【発明が解決しようとする課題】
ところが、上記のような従来例にあっては、係止部７′は横方向に移動して本体部１′の周面から出没自在であるが、操作釦５０は上下方向に移動するので、操作釦５０の上下方向の移動を係止部７′の横方向の移動に変換する必要があり、構造が複雑になるという問題がある。また、操作釦５０の操作が上下方向であり、該操作釦の操作ストロークも必要となるので、必然的に本体部１′の上下方向の厚みが厚くなってしまうという問題がある。更に、照明器具本体４を取り外す時、操作釦５０を操作するには片手の一部の指で操作釦５０を上方に押し上げ操作を行いながら、他の指で照明器具本体４を支えて照明器具本体４を引き下ろすような操作が必要であって、照明器具本体４の取り外しが行いにくいという問題がある。また、１つの操作釦５０で２つの係止部７′が動作するようにしているので、１つの操作釦を操作するための解除操作力が高くなる可能性が大きく、また、一方の係止部７′が動作不良であっても、わかりにくく、照明器具本体４の中途半端な取付けが生じるという危険性があった。更に、電気的接続手段５３を本体部１′の外周面部に設けているので、これが係止部７′と操作釦の係止以外に取付け装置Ａ′の外形寸法が大きくなる要因となり、取付け装置Ａ′の外形寸法が大きくなるという問題があった。
【０００５】
本発明は上記の従来例の問題点に鑑みて発明したものであって、構造が簡単で、本体部の厚みが薄くでき、また、照明器具本体の取り外しが容易に行え、また、本体部の外形寸法も小さくできる照明器具の取付け装置及びこれを備えた照明装置を提供することを課題とするものである。
【０００６】
【課題を解決するための手段】
上記の課題を解決するために、本発明の照明器具の取付け装置は、略円盤状をした外形の本体部１の上面に引っ掛けシーリング２に係止自在とする係止爪３を設け、本体部１の外周面部に本体部１を照明器具本体４の挿入孔５に挿入した状態で照明器具本体４の係合部６へ係止する横方向に移動自在で且つ本体部１の外周面部に対して出没自在な爪状の係止部７と、係止部７の照明器具本体４の係合部６への係止を解除するための操作方向が横方向である本体部１に設けられた解除操作部８と、を備えた照明器具の取付け装置であって、一端側に係止部７を他端側に解除操作部８を有すると共に解除操作部８を横方向に移動させたときに係止部７が横方向の同じ向きに移動する移動体１８を一対設け、この一対の移動体１８を解除操作部８の各々を互いに離れる方向に操作することにより係止部７の各々が略円盤状の本体部１の外周面部の互いに略対称となる位置で没して係止部７が係合部６より解除されるように配置したことを特徴とするものであって、このように、係止部７の移動方向と解除操作部８の移動方向とが同じ横方向であるから、構造が簡略化でき、また、本体部１の上下方向の厚みを薄くでき、さらに照明器具本体４を取り外す際には、両手４８の親指４８ａを除く他の４本の指４８ｂで照明器具本体４を支えた状態で、両手の親指４８ａをそれぞれ横方向に操作して解除操作部８の操作ができて、照明器具本体４を両手４８でバランスよく支持しながら簡単に両係止部７の両係合部６に対する係合を解除できて解除操作が容易に行え、しかもこの場合、両手４８で照明器具本体４を支えながら親指４８ａの自然な横方向の動きにより解除操作部８を操作できて解除操作がより容易に行えるものであり、また、係止部７及び解除操作部８がそれぞれ一対設けてあることで、各々の係止部７の動作の確認をそれぞれの係止部７に対応する別々の解除操作部８により確認することができ、一方の係合が不完全であった場合に容易に確認できることになる。
【０００７】
また、一対の係止部７及び解除操作部８が略円盤状をした外形の本体部１の中心を通り且つ略円盤状をした本体部１の外周面部を横断する直線に沿って設けられ、解除操作部８により操作される係止部７が略円盤状をした本体部１の外周面部の互いに対称となる位置から出没自在とすることが好ましい。このような構成とすることで、本体部１に対して係止部７及び解除操作部８を合理的な配置関係にできることになる。
【０００８】
また、一対の解除操作部８の間に電線接続用のコネクタ９を配置することが好ましい。このような構成とすることで、本体部１の外形寸法を大きくすることなく電気的接続部を設けることができる。
【０００９】
また、コネクタ９に２極のコネクタ電極９ａを設け、上記２極のコネクタ電極９ａが一対の解除操作部８を結ぶ直線と略平行な方向に沿って配置してあることが好ましい。このような構成とすることで、コネクタ９を解除操作部８の移動方向に横長に形成できて、照明器具本体４を取り外す際に、解除操作部８に設けたガイド部１０をそれぞれ解除操作部８の移動方向に横長になったコネクタ９の外面をガイドとして移動でき、また、通常の照明器具本体４の取付け状態では、両解除操作部８に設けたガイド１０間が離れて、コネクタ９への接続のためのスペースが確保できることになる。
【００１０】
また本発明の照明装置は、請求項１〜４のいずれかに記載の照明器具の取付け装置Ａと、この照明器具の取付け装置Ａの本体部１を挿入する挿入孔５と照明器具の取付け装置Ａの係止部７が係止される係合部６とを設けた照明器具本体４とを有する照明器具４０と、を備えてなることを特徴とする。これにより上記作用効果を有する照明器具の取付け装置を備えた照明装置を提供できる。
【００１１】
【発明の実施の形態】
本発明を以下添付図面に示す実施形態に基づいて説明する。
【００１２】
本体部１は略円盤状をしており、本体部１の上面部には図２に示すように、下方に向けて凹設した凹部１１が形成してあり、本体部１の下端部は図１に示すように全面が開口している。上記本体部１の上面部に凹設した凹部１１の下面部から下方に水平断面長方形状をした角筒部９ｃが下方に向けて垂設してある。凹部１１の底部の上面には係止爪３とコネクタ電極９ａとを有する一対の端子板ブロック１２が取付けねじ１３により取付けてある。そして、一対の端子板ブロック１２に設けた一対の係止爪３が本体部１の上面部から上方に突出している。また、一対の端子板ブロック１２に設けた一対のコネクタ電極９ａが角筒部９ｃ内に挿入してあって、このように角筒部９ｃ内に一対のコネクタ電極９ａを内装することでコネクタ９が構成してある。平面視長方形状の角筒部９ｃの長辺方向と平行な方向の一側面にはロック溝部９ｄが設けてあり、このロック溝部９ｄの下端は角筒部９ｃの下端よりも上方に位置しており、また、ロック溝部９ｄの内部にはロック部９ｅが設けてある。
【００１３】
略円盤状をした本体部１の外周面部には図１、図７等に示すように一対の孔１４が形成してあり、この一対の孔１４の位置関係は略円盤状をした本体部１の中心を回転中心とする１８０°回転対称となる位置関係にある。
【００１４】
係止部７は水平板状をしており、この係止部７の先端部は本体部１の外周面部の円弧と同じ曲率半径の円弧となっている。水平板状をした係止部７の後端部の一側端部には下方又は斜め下方に向けて突出した下向き片１５が突設してあり、下向き片１５の下端部から背方に向けて略Ｌ字状をした連結片１７が水平に連出してあり、連結片１７の一片部に縦板状をした解除操作部８の上端部の一側部が連設してあって、移動体１８が構成してある。したがって、連結片１７及び解除操作部８の上端は水平板状をした係止部７よりも下方に位置している。移動体１８の係止部７の後端部の中央部には２条のガイド部１０が解除操作部８側に向けて突出してある。この２条のガイド部１０の突出基部は下方又は斜め下方にむけて突出した段落ち片１０ａとなっており、ガイド部１０の先端部は連結片１７と同じレベルとなっている。上記２条のガイド部１０間がばね材収納部２０となっている。また、係止部７には２つの長孔１９が設けてある。また、解除操作部８にはキャップ８ａが被せられる。
【００１５】
本体部１の内部には２個で一組となった支持軸部２１が２組設けてあり、一組の支持軸部２１に一方の移動体１８の２個の長孔１９をスライド自在に嵌め込み、他の一組の支持軸部２１に他方の移動体１８の２個の長孔１９をスライド自在に嵌め込んである。ここで、上記２個の移動体１８は水平面で１８０°回転した状態となっている。そして、一方の移動体１８の係止部７が本体部１の外周面部の対向部分に設けた一対の孔１４のうちの一方の孔１４から出没自在となっており、他方の移動体１８の係止部７が他方の孔１４から出没自在となっている。また、移動体１８に設けた２条のガイド部１０はコネクタ９の外殻を構成する平面視長方形状の角筒部９ｃの長辺側の側面にスライド自在に嵌まり込んでいて、ガイド部１０が角筒部９ｃの長辺側の側面にガイドされながらスムーズに移動するようになっている。
【００１６】
そして、本発明においては、一対の係止部７及び解除操作部８が略円盤状をした外形の本体部１の中心を通り且つ略円盤状をした本体部１の外周面部を横断する直線に沿って設けてあり、解除操作部８により操作される係止部７が略円盤状をした本体部１の外周面部の互いに対称となる位置に設けた孔１４から出没自在となっていて、全体の配置を合理的な配置にして全体のコンパクト化を図っている。
【００１７】
ここで、本発明においては解除操作部８の操作方向は横方向（水平方向）で、また、係止部７の移動方向も横方向であって、このように解除操作部８の操作方向と係止部７の移動方向とを同じ横方向としたから、上記のように、横方向（水平方向）に移動自在な移動体１８に解除操作部８と係止部７とを一体に設けた簡単な構造で、解除操作部８を横方向に移動させることにより係止部７を横方向に移動させる構造とすることができるものである。また、このように解除操作部８の操作方向と係止部７の移動方向とを同じ横方向とすることで、解除操作部８を上下方向に移動する場合に比べて、上下方向のストロークが必要でないのみならず、従来例のように、上下方向の運動を横方向の運動に変換する変換機構も必要でなく、本体部１の上下方向の厚みを薄くできると共に、構造を簡略化できることになる。
【００１８】
そして、移動体１８の２条のガイド部１０間に形成されたばね材収納部２０にコイルスプリング２３が配設してあり、該コイルスプリング２３の両端部がそれぞれ移動体１８と角筒部９ｃの短辺側の面とに弾接してあって、コイルスプリング２３のばね力により係止部７が孔１４から外側に突出している。この状態が図３、図４、図６、図７、図８、図１０等に示す状態であって、図３に示すように、ガイド部１０の先端部が平面視長方形状の角筒部９ｃの長辺側の側面の両端部近くまで移動し、両移動体１８のガイド部１０間にロック溝部９ｄが露出した状態となっている。また、下方に突出している両側の解除操作部８をコイルスプリング２３に抗して互いに離れる方向に移動させるとガイド部１０の先端部同士が突き当たるようになっており、この状態で係止部７は本体部１の外周面部から内側に引き込むものである。また、ガイド部１０の先端部同士が突き当たった状態では上記ロック溝部９ｄが図１１（ａ）に示すようにガイド部１０により塞がれることになる。
【００１９】
本体部１の下面開口部には補強板を兼用した蓋３０が取付けねじ３１により取付けてあり、該蓋３０には一対の孔３２が設けてあって、一対の移動体１８にそれぞれ設けた下方に垂下した一対の解除操作部８が上記一対の孔３２にスライド自在に挿通してある。また、蓋３０の中央部には中央孔３３が設けてあって、該中央孔３３にコネクタ９の下端部及びロック溝部９ｄの下端部が対向している。ここで、コネクタ９の下端部は中央孔３３にはまり込んでいる。ここで、係止部７が本体部１の外周面部から内側に引き込んだ状態では両ガイド部１０の先端部がロック溝部９ｄの下方開口を塞いでいて中央孔３３から両ガイド部１０の先端部が見えるようになっている。したがって、仮に、両係止部７がいずれも本体部１の外周面部から突出していない場合には、両ガイド部１０の先端部がいずれも中央孔３３に露出して見え、また、両係止部７のうち一方の係止部７が本体部１の外周面部から突出していない場合には、両ガイド部１０のうち一方のガイド部１０の先端部が中央孔３３に露出して見え、当該係止部７が外方に突出していないことが確認できることになる。
【００２０】
ここで、コネクタ９の角筒部９ｃに設けた２極のコネクタ電極９ａは、断面長方形状をした角筒部９ｃの長辺と平行に２極のコネクタ電極９ａを配置してあり、更に、角筒部９ｃの長辺に沿った方向と、一対の解除操作部８を結ぶ直線（つまり移動体１８の移動方向）とが略同じ方向となっているので、角筒部９ｃの長辺の長さを有効利用して、ガイド部１０をガイドとしながら移動体１８を移動して、両ガイド部１０の先端部が離れた状態では上記のように、ロック溝部９ｄをオープンにしてコネクタ９への接続のためのスペースが十分確保できるようになっている。
【００２１】
本体部１には更にロック部材２５が本体部１の上面部より出没自在に取付けてある。該ロック部材２５はばね２６により上方に突出するばね力が付与してあり、該ばね力によりロック部材２５が本体部１の上面部より上方に突出している。
【００２２】
本体部１の周面部の下端部には操作窓部３４が設けてあり、蓋３０には操作窓部３４に対向して切欠部３５が設けてある。切欠部３５内には操作釦２７の操作部３６が移動自在に配置してあり、操作部３６の先端部の溝部３７が蓋３０の切欠部３５の奥の部位にスライド自在に嵌まり込んでいる。操作釦２７には傾斜したカム部３８が設けてあり、カム部３８にロック部材２５の下端部の当たり部３９がばね２６のばね力により弾接している。したがって、通常はばね２６のばね力により当たり部３９が上方に押し上げられ、これにより操作部３６が図１３（ａ）のように本体部１の周面部の内面に当接している。この状態はロック部材２５の上端部が本体部１の上面部よりも上方に突出した状態に設定してある。一方、操作窓３４から指を入れて操作部３６を押すと、図１３（ｂ）のように当たり部３９がばね２６に抗してカム部３８により下方に押し下げられ、これによりロック部材２５の上端部が本体部１の上面部よりも下方に引き込むように設定してある。
【００２３】
以上が本発明に係る取付け装置Ａの構成である。
【００２４】
次に、照明器具４０は図９に示すように、照明器具本体４にランプ４１、器具点灯ブロック４２を装備して構成してあり、照明器具本体４の上面部中央部には挿入孔５が設けてあり、該挿入孔５の縁部に円筒状をしたホルダー４３が設けてあり、ホルダー４３の内周面部に溝が設けてあって、該溝が係合部６を構成している。
【００２５】
天井４４には引っ掛けシーリング２が取付けてあり、引っ掛けシーリング２の下面部には一対の円弧状をした係止孔２ａが設けてあり、係止孔２ａの一端部は巾広孔部２ｂとなっている。
【００２６】
しかして、照明器具４０を天井４４に取付けるには、まず、天井４４に取付けた引っ掛けシーリング２に前述の取付け装置Ａを取付けるものである。取付け装置Ａの取付けに当たっては、まず、本体部１に設けた一対の端子板ブロック１２の係止爪３を係止孔２ａに挿入係止する。この場合、係止爪３は巾広孔部２ｂから挿入して円弧状をした係止孔２ａの他端部まで移動させて機械的、電気的に引っ掛けシーリング２に取付け装置Ａを取付けるのであるが、この状態で、係止爪３が巾広孔部２ｂに位置している状態では引っ掛けシーリング２の下面に押しつけられて弾接していたロック部材２５の先端部が、係止爪３が円弧状をした係止孔２ａの他端部に到った状態で、係止孔２ａの一部（実施形態では巾広孔部２ｂ）内に嵌め込まれて、ロック部材２５を下降させない限り、つまり、操作釦２７を操作しない限り、取付け装置Ａが引っ掛けシーリング２から取り外せないようになっている。
【００２７】
次に、照明器具本体４を手に持って挿入孔５（つまり円筒状のホルダー４３）を取付け装置Ａの円盤状をした本体部１に下方より嵌め込むものである。ここで、本体部１の周面部の対向する位置から一対の移動体１８の係止部７がそれぞれコイルスプリング２３のばね力により外側方に突出しているので、ホルダー４３の嵌め込みにより係止部７がコイルスプリング２３のばね力に抗して内側に押し込まれ、係合部６と係止部７とが対向した時点で、コイルスプリング２３のばね力により係止部７が係合部６に弾性的に係止し、これにより図１１（ｂ）に示すように、照明器具本体４が引っ掛けシーリング２に取付けた取付け装置Ａに取付けられることになる。
【００２８】
このように取付け装置Ａに照明器具４０が取付けられた状態では、取付け装置Ａの本体部１に設けた係止部７がコイルスプリング２３のばね力により外側に飛び出す方向に移動体１８が移動しているので、既に述べたように、ロック溝部９ｄが両移動体１８のガイド部１０により塞がれないで開放した状態となっている。したがって、取付け装置Ａに照明器具４０を取付けた状態では、移動体１８のガイド部１０に邪魔されることなく、照明器具４０に設けたコネクタ４９を中央孔３３に位置するコネクタ９に嵌め込むと共にコネクタ４９に設けたロック受け４９ａをロック溝部９ｄに嵌め込んでロック部９ｅに係止するようになっている。このようにして、照明器具４０が電気的に接続されるものである。図１１（ａ）、図１４（ｂ）にコネクタ４９を接続した状態を示している。
【００２９】
ところで、両係止部７のうち一方の係止部７のみが係合部６に係合している状態でも、一応照明器具本体４は取付け装置Ａに取付けられるので、作業者は両方とも正常に取付けられていると勘違いして、取付け作業を完了してしまうことがあるが、本発明においては、すでに述べたように、一方の係止部７が仮に何らかの理由で外方に突出していない状態（つまり係止部７が係合部６に係合していない状態）ではガイド部１０が中央孔３３に露出して見えるため、一方の係止部７が係合部６に係合していない不完全な取付け状態であることが確認できるものである。また、各々の係止部７の動作の確認をそれぞれの係止部７に対応する別々の解除操作部の位置を確認することによっても、一方の係合が不完全であった場合に容易に確認できるものである。また、仮に、この一方の係止部７が係合部６に係合していない不完全な取付け状態のままコネクタ４９をコネクタ９に接続しようとしても、中央孔３３にガイド部１０が位置していてロック溝部９ｄの開口部の半分が塞がれることになるので、図１４（ａ）のようにロック受け４９ａをロック溝部９ｄに嵌め込むことができず、この段階でも、一方の係止部７が係合部６に係合していない不完全な取付け状態であることが確認できることになる。
【００３０】
一方、照明器具４０の取り外しに当たっては、以下のようにして行うものである。すなわち、まず、ロック受け４９ａとロック部１２ｂとのロックを解除して照明器具４０に設けたコネクタ４９を取り外す。次に、図１２のように両手４８を照明器具本体４の上面部の下面に当て、親指４８ａを除く他の４本の指４８ｂで照明器具本体４を支え、この状態で両方の手４８の親指４８ａをそれぞれ取付け装置Ａの本体部１の下面から下方に垂下している一対の移動体１８に設けた解除操作部８に当て、この状態で両親指４８ａを図１２の矢印方向に移動させることで、両移動体１８の解除操作部８が図１２の矢印方向に移動し、これにより両移動体１８が移動して係止部７が内側に移動して係合部６から離脱するので、そのまま、両手４８で照明器具本体４を下方に引き下ろすことで、取り外すことができるものである。
【００３１】
この場合、解除操作部８の操作方向が横方向（水平方向）であるため、図１２のように両手４８の親指４８ａを除く他の指で照明器具本体４の上面部の下面に当てて支持した状態で両手の親指４８ａを横方向に動かすのみで係止部７を係合部６から離脱させることができて、係合の解除操作が容易に行えて、照明器具本体４の取り外しが容易にできることになる。
【００３２】
また、コネクタ４９を外さない限り（つまり電気的接続を解除しない限り）、解除操作部８を操作しようとしてもロック受け４９ａにガイド部１０が当たって、移動体１８を移動できず、したがって、コネクタ４９を接続した状態では誤って解除操作部８を操作して係止部７を係合部６から外すことができないようになっている。
【００３３】
【発明の効果】
本発明の請求項１記載の発明にあっては、上述のように、略円盤状をした外形の本体部の上面に引っ掛けシーリングに係止自在とする係止爪を設け、本体部の外周面部に本体部を照明器具本体の挿入孔に挿入した状態で照明器具本体の係合部へ係止する横方向に移動自在で且つ本体部の外周面部に対して出没自在な爪状の係止部と、係止部の照明器具本体の係合部への係止を解除するための操作方向が横方向である本体部に設けられた解除操作部と、を備えた照明器具の取付け装置であって、一端側に係止部を他端側に解除操作部を有すると共に解除操作部を横方向に移動させたときに係止部が横方向の同じ向きに移動する移動体を一対設け、この一対の移動体を解除操作部の各々を互いに離れる方向に操作することにより係止部の各々が略円盤状の本体部の外周面部の互いに略対称となる位置で没して係止部が係合部より解除されるように配置してあるので、解除操作部の操作方向と係止部の移動方向とを同じ方向としたので、解除操作部の操作方向と係止部の移動方向とが異なる方向である従来例に比べて、本体部の上下方向の厚みを薄くでき、また、構造を簡単にできて一体化も可能となり、組立て性も向上し、さらに照明器具本体を取り外す際には、両手の親指を除く他の指で照明器具本体を支えた状態で、両手の親指をそれぞれ横方向に操作して解除操作部の操作ができて、照明器具本体を両手でバランスよく支持しながら簡単に両係止部の両係合部に対する係合を解除できるものであり、しかもこの場合、両手で照明器具本体を支えながら親指の自然な横方向の動きにより解除操作部を操作できて解除操作がより容易に行えるものであり、また、各々の係止部の動作の確認をそれぞれの係止部に対応する別々の解除操作部により確認することができ、一方の係合が不完全であった場合に容易に確認できるものである。
【００３４】
また、請求項２記載の発明にあっては、上記請求項１記載の発明の効果に加えて、一対の係止部及び解除操作部が略円盤状をした外形の本体部の中心を通り且つ略円盤状をした本体部の外周面部を横断する直線に沿って設けられ、解除操作部により操作される係止部が略円盤状をした本体部の外周面部に互いに対称となる位置から出没自在としてあるので、本体部に対して係止部及び解除操作部を合理的な配置関係にできて、コンパクト化が図れるものである。
【００３５】
また、請求項３記載の発明にあっては、上記請求項２記載の発明の効果に加えて、一対の解除操作部の間に電線接続用のコネクタを配置してあるので、電気的接続手段が本体部の外周面部に位置する従来例に比べて本体部の外形寸法を大きくすることなく電気的接続部を設けることができることになる。
【００３６】
また、請求項４記載の発明にあっては、上記請求項３記載の発明の効果に加えて、コネクタに２極のコネクタ電極を設け、上記２極のコネクタ電極が一対の解除操作部を結ぶ直線と略平行な方向に沿って配置してあるので、コネクタを解除操作部の移動方向に横長に形成できて、照明器具本体を取り外す際に、解除操作部に設けたガイド部をそれぞれ解除操作部の移動方向に横長になったコネクタの外面をガイドとして移動でき、また、通常の照明器具本体の取付け状態では、両解除操作部に設けたガイド間が離れて、コネクタへの接続のためのスペースが確保できるものである。
【００３７】
また、請求項５記載の発明にあっては、上記作用効果を有する照明器具の取付け装置を備えた照明装置を提供できる。
