Description

【０００１】
【発明の属する技術分野】
この発明は、複数のＬＥＤを光源として基板に実装したＬＥＤ集積光源を用いたＬＥＤ光源装置に関し、特にＬＥＤ集積光源とこのＬＥＤ集積光源に給電するソケットの構造に関する。
【０００２】
【従来の技術】
図１６は特開２０００−１００２１９号公報に記載された従来のＬＥＤ集積光源の斜視図である（従来例１）。図において、４１はＬＥＤ光源、４２は折り曲げ部４２ａを有する１枚の基板であり、表面に複数のＬＥＤ光源４１が搭載され、裏面には各ＬＥＤに通電するための電極が基板４２の両側縁部に設けられている。４３は電路を兼ねた断面コの字形の金属枠であり、端子部４４と基板４２の電極を接触させるようにＬＥＤ基板の両縁部に嵌めて圧接して基板４２と一体化し湾曲させている。
このように構成されたＬＥＤ光源装置は、端子部４４の孔を介してねじ１５によりＬＥＤ光源装置本体のハウジング本体のボス部４５に取り付けられる。電源コード１８は端子部４４にねじ１５で共締めされ、ＬＥＤ光源４１を実装した基板４２への電気的接続が行われる。
【０００３】
図１７は特開２００２−９３２０４号公報に記載されたＬＥＤ光源装置の斜視図である（従来例２）。図において、４６はＬＥＤ集積光源ユニットであり、基板４７、ＬＥＤ光源４１、基板４７の両縁に設けられたコネクタ４８ａから構成される。
４７は複数のコネクタ４８ｂを備えたマザーユニットであり、マザーユニット４７の複数のコネクタ４８ｂに各々ＬＥＤユニット４６のコネクタ４８ａを挿入して取付けると同時に電気的接続がなされＬＥＤ光源装置が構成される。
【０００４】
図１８は特開２０００−３０６４１８号公報に記載されたＬＥＤを用いた棒状ランプの斜視図（従来例３）である。図において、４１は支持板に支持された複数のＬＥＤ光源、４９はＬＥＤ光源４１の両電極端子が電気的接続された端子板、５２は端子板を配設したコネクター部、５０は電気接続用コネクタ５１の電源ピンである。この構成において、ＬＥＤ光源４１は、電気接続用コネクタ５１に設けられた電源ピン５０により電気的に接続される。
【０００５】
【発明が解決しようとする課題】
しかしながら、上記のような従来のＬＥＤ光源４１を実装した基板４２の光源装置本体への取付け及び電気的接続において、従来例１ではＬＥＤ光源４１を実装した基板４２を取り換える際は、光源装置本体にねじ１５でねじ止めをするとともに電気的接続を行う必要があり簡単でなかった。従来例２では、マザーユニット４７にコネクタ４８ａ、４８ｂを介してＬＥＤユニット４６を一本づつ取付ける必要があり簡単ではなく、また、基板４７の強度が不足して光源の交換時に不具合が生じる恐れがあった。従来例３ではＬＥＤ光源４１の電極端子を端子板４９に接続し、さらに、この端子板４９を電気接続用コネクタ５１により接続をする必要があり、いずれも交換が容易でなく、使用者が交換するものでなく、基板単体で入手もできないという問題があった。
【０００６】
また、従来例１〜３のいずれも、基板４２、４６等と光源装置本体を構成するケースの取付け面の間に空間があり、ＬＥＤ光源４１から発生した熱が放熱しにくくＬＥＤ光源４１の素子温度が高くなり、結果としてＬＥＤ光源４１の寿命が短くなるという問題があった。
【０００７】
この発明は上記のような問題点を解消するためになされたもので、複数のＬＥＤ光源を基板に実装したＬＥＤ集積光源であるＬＥＤ集積光源ユニットを白熱電球、蛍光ランプなどと同様に簡単に交換でき、また、ＬＥＤ光源の温度を低く抑制して寿命を長くし、さらに、ＬＥＤ集積光源ユニットを連結して大きな集積光源化を図った信頼性の高いＬＥＤ光源装置を提供することを目的とする。
【０００８】
【課題を解決するための手段】
この発明に係るＬＥＤ光源装置は、装置本体と、一端に給電部を他端に非給電部を有する電路パターンを設けた基板に複数のＬＥＤを光源として実装したＬＥＤ集積光源ユニットと、上記装置本体に設けられ上記ＬＥＤ集積光源ユニットの給電部側端部を着脱自在に保持するとともに上記ＬＥＤ集積光源ユニットに給電するソケットと、このソケットに対向して上記装置本体に設けられ上記ＬＥＤ集積光源ユニットの非給電部側端部を保持する保持部と、を備え、上記ソケットは、上記ＬＥＤ集積光源ユニットの上記給電部側端部を挿入する挿入部と、この挿入部に設けられ上記ＬＥＤ集積光源ユニットの上記給電部に接触するように配設されたばね性を有する端子板と、を備え、上記保持部は、保持カバーと、この保持カバー内に設けられ、挿入・排出方向に摺動自在に摺動し、上記ＬＥＤ集積光源ユニットの上記非給電部側端部を保持する保持片と、この保持片をＬＥＤ集積光源ユニット側に付勢する付勢手段と、を備えたものである。
【０００９】
また、ソケットを装置本体から遠ざかる方向に回動可能に上記装置本体に取付けるようにしたものである。
【００１０】
また、装置本体と、一端に給電を行うランプ口金とこのランプ口金に接続された電路パターンを有する基板に複数のＬＥＤを光源として実装したＬＥＤ集積光源ユニットと、上記装置本体に設けられ上記ＬＥＤ集積光源ユニットの上記ランプ口金を着脱自在に保持するとともに上記ＬＥＤ集積光源ユニットに給電するソケットと、を備え、上記ランプ口金は、上記基板の一端に設けられた口金絶縁部と、上記口金絶縁部に固定され、一端が上記基板の上記電路パターンに接続され他端が上記口金絶縁部から突出した一対のランプピンとを備え、上記ソケットは、上記ＬＥＤ集積光源ユニットの上記ランプ口金が挿入される挿入部と、この挿入部に設けられ上記ランプ口金の上記ランプピンが挿嵌される受けばねとを備えたものである。
【００１１】
また、ＬＥＤ集積光源ユニットのランプ口金と反対側に基板の電路パターンに接続された一対の受けばねを有する連結部を備え、上記連結部の上記受けばねに他のＬＥＤ集積光源ユニットのランプ口金のランプピンを挿嵌することにより、複数のＬＥＤ集積光源ユニットを連結可能としたものである。
【００１２】
また、ＬＥＤ集積光源ユニットの口金絶縁部に設けられた誤接続防止用の凹部または凸部と、ソケットの内側に、上記ＬＥＤ集積光源ユニットが挿入されたとき、上記口金絶縁部に設けられた上記凹部または凸部が係合する係合部を設けたものである。
【００１３】
また、ＬＥＤ集積光源ユニットの表面に薄板状の絶縁カバーを配設したものである。
【００１４】
また、ＬＥＤを実装した基板の長手方向の両端部にそれぞれ断面略コの字状の補強部材を嵌合したものである。
【００１５】
また、ＬＥＤ集積光源ユニットをソケットへ取付けたときに、前記ＬＥＤ集積光源ユニットが接触する凸状の平面部を装置本体に設けたものである。
【００１６】
また、凸状の平面部に熱伝導シートを設けたものである。
【００１７】
【発明の実施の形態】
実施の形態１．
図１はこの発明の実施の形態１に係るＬＥＤ光源装置を示す斜視図、図２は図１のＬＥＤ光源装置の要部構成要素のＬＥＤ集積光源ユニットとこのＬＥＤ集積光源ユニットに電気を給電するためのソケットと保持部の分解斜視図、図３は図２に示す要部構成部材をさらに分解した詳細な分解斜視である。図４はＬＥＤ集積光源ユニットをソケットに取り付けた状態を示す要部正面図、図５はＬＥＤ集積光源ユニットをソケットに取り付けた状態を示す要部断面図、図６はＬＥＤ集積光源ユニットの取付け要領を示す部分断面図である。
【００１８】
図１において、ＬＥＤ光源装置は、このＬＥＤ光源装置本体２７の下面凹部に設けられた平面部４と、ＬＥＤ集積光源ユニット１、この平面部４に取り付けられＬＥＤ集積光源ユニット１の一端が挿入され電気的接続をするソケット２と、ＬＥＤ集積光源ユニット１の他端部を支持する保持部３がそれぞれ４個配設されている。
図２において、ＬＥＤ集積光源ユニット１は、表面実装用のＬＥＤ光源８と電路パターン９を形成した基板７より構成され、９ａは給電部、９ｂは非給電部、であり、７ａは給電部側端部、７ｂは非給電部側端部である。ソケット２はＬ形受け部１１、Ｌ形受け部カバー１２を備え、保持部３は、保持片である摺動支持片１４と摺動支持片を保持する保持カバーである摺動片固定カバー１６を備える。
【００１９】
次に、図３によりＬＥＤ光源装置の構成を詳細に説明する（図１、２に示したものは一部省略）。１０はＬＥＤ集積光源ユニット１の電路パターン９を絶縁保護するための絶縁カバー、２は内部にバネ性を有する導電性金属の帯板を湾曲させて形成された一対のＬ形の端子板１３とこの端子板１３の外郭となるＬ形受け部１１及び両側壁に円筒状の一対の凸部５を形成したＬ形受け部カバー１２から構成されるソケット、３７は上記円筒状の凸部５と回動自在に嵌合するＬ形金具、３はＬＥＤ集積光源ユニット１をソケット２に挿入する際その挿入方向に摺動自在に可動する摺動支持片１４とこの摺動支持片１４を上記ソケット２の方向に付勢する板ばね１７と上記摺動支持片１４及び板ばね１７を内蔵する摺動片固定カバー１６から構成される保持部である。２９は摺動支持片１４の下側に形成された摺動支持片１４の操作用取っ手である。
なお、絶縁カバー１０に白色塗装を行えば反射板も兼ねることができる。
【００２０】
以上の各部材をを取付けた状態の側面図が図４であり断面図が図５である。図４、５において図１〜３で説明した部分は説明を省略する。４ａは装置本体の平面部４に形成した凸状の平面部であり、ＬＥＤ集積光源ユニット１をソケットへ取付けたときに、ＬＥＤ集積光源ユニット１が接触するようにしている。
なお、ＬＥＤ用の電源はＬＥＤ集積光源ユニット１内か本体内に設けられる。
【００２１】
次に、ＬＥＤ集積光源ユニット１を本体２７の平面部４に取り付ける手順を図６により説明する。
まず、ソケット２を円筒状の凸部５を中心にＬＥＤ光源装置本体２７の平面部４から遠ざかる方向に回動させ、ＬＥＤ集積光源ユニット１を取り付けやすい位置にする。そして、ＬＥＤ集積光源ユニット１の給電側端部７ａをソケット２に挿入すると、一対の端子板１３がＬＥＤ集積光源ユニット１の電路パターン９の給電部９ａが接触して電気的接続がされるとともに、ＬＥＤ集積光源ユニット１がＬ形受け部１１側に付勢され、ＬＥＤ集積光源ユニット１がソケット２に固定される。
【００２２】
次に、ＬＥＤ集積光源ユニット１を含めてソケット２を円筒状の凸部５を中心にＬＥＤ光源装置本体２７の平面部４の側に回動させ保持部３を構成する摺動片固定カバー１６の基台３８部分に密着させる。このとき、摺動支持片１４は操作用取っ手２９をソケット２と反対方向に摺動させＬＥＤ集積光源ユニット１がぶつからないようにする。
【００２３】
そして、ＬＥＤ集積光源ユニット１の非給電側端部７ｂを基台３８に密着させた後、摺動支持片１４の操作用取っ手２９から手を離すと、板バネ１７の付勢力により摺動支持片１４がソケット２の方に摺動し、摺動支持片１４の支持部１４ａがＬＥＤ集積光源ユニット１の下側に位置するようになりＬＥＤ集積光源ユニット１が固定される。
このとき、ＬＥＤ集積光源ユニット１のＬＥＤ光源装置本体２７側の平面部４に形成された金属の凸状平面部４ａがＬＥＤ集積光源ユニット１の基板７のＬＥＤ光源８を実装していない背面に接触し、ＬＥＤ光源８で発生した熱が基板７を通して効率よく放熱される。
なお、図４〜６には示してないが、凸状平面部４ａに熱伝導シートを設けてさらに熱伝導効率をよくしてもよい。
【００２４】
以上のように、ＬＥＤ集積光源ユニット１を、ＬＥＤ光源装置本体に工具を使用して装置を分解したり、ねじ止め等することなく白熱電球、蛍光ランプなどと同様に簡単な操作でソケット２に着脱することができる。
また、ＬＥＤ集積光源ユニット１をソケット２へ取付けたときに、ＬＥＤ集積光源ユニット１が接触する凸状の平面部４ａを装置本体２７に設けたので、放熱効果が高くＬＥＤ光源８の温度を低く抑制することができ、ＬＥＤ光源の寿命を長くすることができる。
また、凸状の平面部４ａに熱伝導シートを設けたので、より放熱効果が高くＬＥＤ光源８の温度をより低く抑制することができ、ＬＥＤ光源８の寿命をより長くすることができる。
また、ソケット２を回動できるので、保持部３の摺動支持片１４の摺動ストロークを小さくでき、保持部３を小型にすることができる。
また、ＬＥＤ集積光源ユニットの表面に薄板状の絶縁カバーを配設したので、ＬＥＤ集積光源ユニットを保護することができる。
【００２５】
実施の形態２．
実施の形態１はソケットを回動可能に本体に取付けたが、本実施の形態はソッケトを本体に固定したものである。
図７は、この発明の実施の形態２に係るＬＥＤ光源装置の断面図であり、ＬＥＤ集積光源ユニットをソケットと保持部に取付けた状態を示す図、図８はＬＥＤ集積光源ユニットをソケットに取付ける手順を示す図である。
【００２６】
図において、実施の形態１の図５、６と同じまたは同等の部分には同一の符号を付し説明を省略する。図に示すようにソケット２は実施の形態１とほぼ同じ構成であるが円筒状の凸部５はなく本体２７の平面部４に固定されている点が異なり、また、保持部３の構成も実施の形態１とほぼ同じであるが摺動片１４の摺動ストローク、板バネ１７のストローク、摺動支持片１４の支持部１４ａと摺動片固定カバー１６の摺動方向長さを各々実施の形態１より長くしている。
なお、摺動支持片１４の支持部１４ａの長さをＬ、ＬＥＤ集積光源ユニット１のソケット２に挿入部の長さをＬ１、ＬＥＤ集積光源ユニット１の保持部３の支持部１４ａに支持される長さをＬ２、支持部１４ａが摺動片固定カバー１６に支持されている長さをＬ３とすると、ＬはほぼＬ１＋Ｌ２＋Ｌ３となるようにする。
【００２７】
次に、図７、図８によりＬＥＤ集積光源ユニット１の取付けを説明する。図８（ａ）はＬＥＤ集積光源ユニット１をソケット２に取り付ける直前の状態を示す図、図８（ｂ）はＬＥＤ集積光源ユニット１をソケット２に取り付けた状態を示す図である。
【００２８】
まず、図８（ａ）に示すように、ＬＥＤ集積光源ユニット１を取り付ける前に摺動支持片１４の取っ手２９をソケット２と反対方向に摺動させておく。この操作によりＬＥＤ集積光源ユニット１をＬＥＤ光源装置本体の平面部４の凸状の平面４ａとほほ平行かつ密着状態にできる。次に、図８（ｂ）に示すようにＬＥＤ集積光源ユニット１の給電部側端部７ａをソケット２に挿入する。この操作により一対の端子板１３がＬＥＤ集積光源ユニット１の電路パターン９の給電部９ａに接触して電気的接続がされるとともに、ＬＥＤ集積光源ユニット１がＬ形受け部１１側に付勢され、ＬＥＤ集積光源ユニット１がソケット２に固定される。
【００２９】
この状態で取っ手２９から手を離すと、板バネ１７の付勢力により摺動支持片１４がソケット２の方に摺動し、手動片１４の支持部１４ａがＬＥＤ集積光源ユニット１の非給電部側７ｂの下側に位置するようになりＬＥＤ集積光源ユニット１が固定される。
このとき、ＬＥＤ集積光源ユニット１のＬＥＤ光源装置本体２７側の平面部４に形成された凸状平面部４ａがＬＥＤ集積光源ユニット１の基板７の背面４が接触しＬＥＤ光源８で発生した熱が基板７を通して効率よく放熱される。
【００３０】
以上のように、ソケット２に回動機構が不要であり、また、回動によりソケット２から電源に接続される電線に力が加わらないので、加工、組み立ても簡単になり製造コストを低減でき、また、電気的及び機械的な信頼性向上を図ることができる。
【００３１】
実施の形態３．
本実施の形態は、実施の形態１、２に示したＬＥＤ集積光源ユニットのＬＥＤ集積光源ユニットは薄い形状で特に長手方向の曲げ等に対して強度的に弱い点があるので補強したものである。
図９はこの発明の実施の形態３に係るＬＥＤ光源装置の要部を示す斜視図である。図において実施の形態１の３、５等と同一の部分には同一の符号を付し説明を省略する。１９はＬＥＤ集積光源ユニット１の基板７の長手方向の両端部にそれぞれ設けられた断面略コの字状の補強部材である。
【００３２】
このような構成により、ＬＥＤ集積光源ユニットの長手方向の曲げ等に対する強度を高くし信頼性の向上を図ることができる。
【００３３】
なお、本実施の形態では、ＬＥＤ集積光源ユニット１の基板７の長手方向の両端部に補強部材１９を設けたが、短手方向の両端部、または、非給電部側端部７ｂにも補強部材を取り付け全体の強度を高くしてもよい。
【００３４】
実施の形態４．
図１０はこの発明の実施の形態４に係るＬＥＤ光源装置の要部を示す部分破断斜視図、図１１は同じく要部断面図、図１２は同じく平面図である。
図１０〜１２において、３０はＬＥＤ集積光源ユニット、２８はＬＥＤ集積光源ユニット３０が挿入され、ＬＥＤ集積光源ユニット３０への給電とＬＥＤ集積光源ユニット３０を保持をするソケット、１８はソケット２８に接続された電線である。なお、ソケット８は実施の形態１の図４と同様に本体２７の平面部４に取り付けられ、ＬＥＤ集積光源ユニット３０の裏面が平面部４の凸部平面部４ａに接触するようにする。
【００３５】
ＬＥＤ集積光源ユニット３０において、７は基板、８は基板７に搭載されたＬＥＤ光源、９は基板７に形成した電路パターン、３２はランプ口金であり、基板７の一端に設けられた口金絶縁部３１とこの口金絶縁部３１に固定され、口金絶縁部３１の両端から凸出し、一端が電路パターン９に電気的に接続され他端がソケット２８の受けバネ２１に挿入される一対のランプピン２０から構成される。１９は基板７の長手方向の両端部を補強する為の断面コの字形状の補強部材、２２はランプ口金３２が設けられた端部と反対側の端部に設けられた端部補強部材である。
【００３６】
ソケット２８において、３４はＬＥＤ集積光源ユニット１のランプ口金３２が挿入される側が開口した挿入部３４ａを有する略直方体形状のソケット枠体、２１はソケット枠体３４の内部に配設され、ＬＥＤ集積光源ユニット１のランプ口金３２のランプピン２１が係合されるバネ性を有する導電性金属の帯板状の受けばねである。
また、ＬＥＤ集積光源ユニット１のランプ口金３２の口金絶縁部３１には誤挿入防止用の凹部３３、ソケット２８の枠体３４の挿入部３４ａには、誤挿入防止用の凹部３３に係合する凸部３５が設けられている。
【００３７】
次に、ＬＥＤ集積光源ユニット１を本体２７の平面部４に取り付けたソケット２８に取り付ける手順を図１１により説明する。
ＬＥＤ集積光源ユニット３０のランプ口金３１をソケット２８の挿入部３４ａに挿入すると、一対のランプピン２１がソケット２８の受けバネ２１に挿嵌され電気的接続がされ、ランプ口金３１が挿入部３４ａで保持されてＬＥＤ集積光源ユニット３０がソケット２８に固定される。
このとき、ＬＥＤ集積光源ユニット３０のＬＥＤ光源装置本体２７側の平面部４に形成された凸状平面部４ａが、ＬＥＤ集積光源ユニット３０の基板７の背面が接触する。
【００３８】
なお、ＬＥＤ集積光源ユニット１がソケット２８に適合したものでないときは、ＬＥＤ集積光源ユニット３０のランプ口金３２の口金絶縁部３１に設けられた誤挿入防止用の凹部３３が、ソケット２８の枠体３４の挿入部３４ａに設けられた誤挿入防止用の凸部３５が合わずにソケット２８に挿入できない。
【００３９】
以上のように、ＬＥＤ集積光源ユニット３０は、従来からある白熱電球、蛍光ランプと同様に一つの完成したランプとして扱うことができる。したがってＬＥＤ集積光源ユニット３０を交換を容易にすることができる。
また、ＬＥＤ集積光源ユニット１の口金絶縁部３１に設けられた誤接続防止用の凹部３３と係合する凸部３５をソケット２８の内側に設けたので、ＬＥＤ集積光源ユニット１の誤接続を防止することができる。
【００４０】
実施の形態５．
実施の形態４では、ＬＥＤ集積光源ユニットをソケットに１つ取り付けたものであるが、本実施の形態はＬＥＤ集積光源ユニットを複数取り付け可能としたものである。図１３はこの発明の実施の形態５に係るＬＥＤ光源装置の要部を示す部分破断斜視図、図１４は同じく断面図、図１５は同じく平面図である。
図において実施の形態４の図１０、１１と同一の部分には同一の符号を付し説明を省略する。
【００４１】
２５はＬＥＤ集積光源ユニット３６のランプ口金３２の反対側に設けられ、他のＬＥＤ集積光源ユニット３６を連結する連結部であり、基板７の端部の補強も兼ねている。この連結部２５は、絶縁性材料で形成した中空の直方体で、一端の開口部に基板７が固定され、他端の閉じた面に他のＬＥＤ集積光源ユニット３６ランプ口金３２の一対のランプピンが挿入される一対の挿入穴２４を有し、内部には、挿入穴２４を介して挿入されるランプピン２０が挿嵌されるピン受けばね２３が設けられ、このピン受けばね２３は導電ピン２６を介して基板７の電路パターン９に接続されている。
なお、電路パターン９は、他のＬＥＤ集積光源ユニット３６が連結できるパターンとしている。
【００４２】
この構成において、ソケット２８に取り付けたＬＥＤ集積光源ユニット３６に他のＬＥＤ集積光源ユニット３６を連結するには、他のＬＥＤ集積光源ユニット３６のランプ口金３１の一対のランプピン２０をソケット２８に取り付けたＬＥＤ集積光源ユニット３６の連結部２５の挿入穴２４を介して受けバネ２３に挿嵌して電気的、機械的に接続する。
【００４３】
以上のように、ＬＥＤ集積光源ユニット３６は他のＬＥＤ集積光源ユニットと電気的、機械的に接続が可能であり、ＬＥＤ集積光源ユニットを複数取り付けて大きな光源や大光束の光源として使用することができる。
【００４４】
なお、本実施の形態では、２つのＬＥＤ集積光源ユニット３６を連結した場合を示したが、３つ以上の連結でもよく、連結したＬＥＤ集積光源ユニット３６の端部か中間部を保持部材で支持するようにしてもよい。
また、実施の形態４で示したＬＥＤ集積光源ユニット３０を一番端に連結してもよい。
【００４５】
【発明の効果】
以上のように、この発明によれば、装置本体と、一端に給電部を他端に非給電部を有する電路パターンを設けた基板に複数のＬＥＤを光源として実装したＬＥＤ集積光源ユニットと、上記装置本体に設けられ上記ＬＥＤ集積光源ユニットの給電部側端部を着脱自在に保持するとともに上記ＬＥＤ集積光源ユニットに給電するソケットと、このソケットに対向して上記装置本体に設けられ上記ＬＥＤ集積光源ユニットの非給電部側端部を保持する保持部と、を備え、上記ソケットは、上記ＬＥＤ集積光源ユニットの上記給電部側端部を挿入する挿入部と、この挿入部に設けられ上記ＬＥＤ集積光源ユニットの上記給電部に接触するように配設されたばね性を有する端子板と、を備え、上記保持部は、保持カバーと、この保持カバー内に設けられ、挿入・排出方向に摺動自在に摺動し、上記ＬＥＤ集積光源ユニットの上記非給電部側端部を保持する保持片と、この保持片をＬＥＤ集積光源ユニット側に付勢する付勢手段と、を備えたので、ＬＥＤ集積光源ユニットを装置本体にねじによる取付け、取外し等をすることなく簡単に交換することができる。
