Description

【０００１】
【発明の属する技術分野】
この発明は、ＬＥＤ照明器具に関するものである。
【０００２】
【従来の技術】
ＬＥＤを使用した照明器具が小型・長寿命を特徴として開発されてきている。しかし、今までは橙色ＬＥＤを使った補助照明（足元灯など）を主とした照明装置の開発や赤色ＬＥＤを使用した表示灯などが主である。
【０００３】
近年、青色ＬＥＤが開発され、その後、白色のＬＥＤも開発された。白色の光をＬＥＤで得られるようになり、スポット照明などにも使用されるようになってきた。しかしながら、現在開発されている白色ＬＥＤは光出力を高く得ようとするＬＥＤの温度が高くなり、ＬＥＤのベアチップを覆っている樹脂の劣化が早く進み光出力が低下する。そのために白色ＬＥＤを用いた照明器具においては、ＬＥＤ部分のノーメンテナンスと言い難いが現在商品化されている照明器具はＬＥＤ部分の交換できる商品がないのが現状である。
【０００４】
【発明が解決しようとする課題】
上記のように白色ＬＥＤを用いた照明器具においては、ＬＥＤ発光部分は照明器具に一体的に組み込まれているので、ＬＥＤの交換作業が単独では行えず、照明器具毎の交換もしくは専用業者での作業となり、一般ユーザにとって不便である。
【０００５】
また、例えば特開２００１−５２５０４号に開示されたＬＥＤを利用した照明装置がある。この照明器具では、ＬＥＤ発光部分を交換できるようにしているが、従来の一般ランプ用のソケットに取り付け可能な事例であるため、当該ソケットを照明器具内に組み込む必要があり、照明器具の厚みが増加してしまう欠点がある。
【０００６】
したがって、この発明の目的は、照明器具に使用されるＬＥＤ部分をモジュール化し交換構造を持たせ、薄型の器具構造を得ることができるＬＥＤ照明器具を提供することである。
【０００７】
【課題を解決するための手段】
上記課題を解決するためにこの発明の請求項１記載のＬＥＤ照明器具は、ＬＥＤチップを搭載した略平板状で円形のＬＥＤモジュールと、前記ＬＥＤモジュールに接続される接続端子と、一方に開口を有する円筒状の側壁の内側に前記ＬＥＤチップ搭載面が前記開口に面するように前記ＬＥＤモジュールおよび前記接続端子が配置された器具本体と、前記接続端子に導通するように接続されたＬＥＤ供給電源部とを備えたＬＥＤ照明器具において、前記ＬＥＤモジュールを前記器具本体の開口に挿入する方向に沿って前記接続端子が設けられ、前記ＬＥＤモジュールの側面に、前記接続端子側に接続して前記ＬＥＤ供給電源部より前記ＬＥＤモジュールへ給電する給電端子部を設けた。
【０００８】
このように、ＬＥＤモジュールを器具本体の開口に挿入する方向に沿って接続端子が設けられ、ＬＥＤモジュールの側面に、接続端子側に接続してＬＥＤ供給電源部よりＬＥＤモジュールへ給電する給電端子部を設けたので、ＬＥＤモジュールを交換可能であり、かつ照明器具の厚みを薄くすることができる。また、ＬＥＤモジュールの交換取付時に強く押し付けられても、その力の方向に給電端子部が接触しないようにできるので給電端子部や接続端子へは直接的に力が伝わらず変形や接触不良等の恐れが低い。また、給電端子部をＬＥＤモジュールの側面に設けることで、ＬＥＤモジュールの挿入時にガイド機能にもなる。
【０００９】
また、ＬＥＤモジュールを円形とすることでモジュールと器具本体の嵌合状態が良くなる。また、モジュールの片側よりによる接触状態の悪化を軽減でき、がたつきが小さくなる。
【００１０】
請求項２記載のＬＥＤ照明器具は、請求項１記載のＬＥＤ照明器具において、給電端子部はＬＥＤモジュール端部の外側面に設けた。このように、給電端子部はＬＥＤモジュール端部の外側面に設けたので、ＬＥＤモジュールが中途半端に傾いた取り付け時は接触しにくくなり、異常取付点灯状態になりにくく安全である。
【００１１】
請求項３記載のＬＥＤ照明器具は、請求項１記載のＬＥＤ照明器具において、給電端子部はＬＥＤモジュールの平面範囲内に開口した孔部の内側面に設けた。このように、給電端子部はＬＥＤモジュールの平面範囲内に開口した孔部の内側面に設けたので、接続端子はＬＥＤモジュールの範囲内に形成できコンパクトな器具が実現できる。
【００１２】
請求項４記載のＬＥＤ照明器具は、請求項１記載のＬＥＤ照明器具において、給電端子部はＬＥＤモジュールの側面よりピン状に突出してその周囲から接続可能とした。このように、給電端子部はＬＥＤモジュールの側面よりピン状に突出してその周囲から接続可能としたので、接続時の装着方向を問わず、ＬＥＤモジュールと接続端子の位置関係は上下どちらでもかまわない。また、器具が複数形態あっても１つのＬＥＤモジュールで対応可能である。
【００１３】
請求項５記載のＬＥＤ照明器具は、請求項１，２，３または４記載のＬＥＤ照明器具において、ＬＥＤモジュールを保持すると同時にＬＥＤ供給電源部と接続端子を介して電気的に接続される機能を有した外郭部材を備え、給電端子部は前記外郭部材と接続される。このように、ＬＥＤモジュールを保持すると同時にＬＥＤ供給電源部と接続端子を介して電気的に接続される機能を有した外郭部材を備え、給電端子部は前記外郭部材と接続されるので、外郭部材を取り付けた後に電気的に接続され、ＬＥＤモジュール取り付け時の感電等の恐れがない。
【００１４】
請求項６記載のＬＥＤ照明器具は、請求項５記載のＬＥＤ照明器具において、外郭部材はＬＥＤモジュールの前面に設けたレンズである。このように、外郭部材はＬＥＤモジュールの前面に設けたレンズであるので、レンズを装着してはじめて通電する構造となる。また、レンズを利用することで外郭部材を別に設ける必要はない。
【００１５】
請求項７記載のＬＥＤ照明器具は、請求項１，２，３，４，５または６記載のＬＥＤ照明器具において、ＬＥＤモジュールを中心軸周りに回転操作することにより給電端子部が電気的に接続される。このように、ＬＥＤモジュールを中心軸周りに回転操作することにより給電端子部が電気的に接続されるので、簡単で確実に操作可能である。また、ＬＥＤモジュールは円形であるため、回転操作時のＬＥＤモジュール回転領域の半径を、チップ搭載面積が同じ方形ＬＥＤモジュールに比べ、小さくすることが可能である。つまり器具本体のＬＥＤモジュール収納部分を小さくできる。
【００１６】
【発明の実施の形態】
この発明の第１の実施の形態を図１ないし図５に基づいて説明する。図１はこの発明の第１の実施の形態のＬＥＤ照明器具の分解斜視図、図２はこの発明の実施の形態のＬＥＤ照明器具の組立状態を示す斜視図、図３はこの発明の実施の形態のＬＥＤ照明器具の取付状態を示す概略図である。
【００１７】
図１〜３に示すように、このＬＥＤ照明器具は、複数のＬＥＤチップ４を搭載した略平板状で円形のＬＥＤモジュール１と、ＬＥＤモジュール１に接続される接続端子２と、ＬＥＤモジュール１および接続端子２が配置される器具本体３と、接続端子２に導通するように接続されたＬＥＤ供給電源部５と、ＬＥＤモジュール１の下方に配置されるレンズ７と、レンズ７の周囲を覆った状態でこれを支持し器具本体３に取り付けられる器具カバー８とを備えている。
【００１８】
器具本体３は中心に電源線９が挿通され、側壁の下端にガイド凸部３ｂが設けてある。接続端子２は電源線９によりＬＥＤ供給電源部５に接続されている。この場合、接続端子２は導電板であり、接続器１０の両端に垂下した状態で設けてある。また、接続器１０の中央にＬＥＤモジュール１の取付ガイド１３が設けてある。この取付ガイド１３は先端に係止部１３ａを有する。
【００１９】
ＬＥＤモジュール１の側面には、ＬＥＤ供給電源部５よりＬＥＤモジュール１へ給電する給電端子部１１を設けている。この給電端子部１１はＬＥＤモジュール１の外側面に、接続端子２と接触可能なように配置される。また、ＬＥＤモジュール１の基板１ａの端縁にガイド凸部３ｂが嵌合するガイド凹部１ｂが設けられ、中心に取付ガイド１３が挿入される孔部１ｃが設けられる。取付ガイド１３の挿入状態で係止部１３ａが孔部１ｃの周縁に係止する。
【００２０】
また、ＬＥＤ供給電源部５は取付板１２の上に設置され、取付板１２に設けた開口に器具本体３を取付けている。
【００２１】
上記構成のＬＥＤ照明器具の組立状態について説明する。図４はこの発明の第１の実施の形態のＬＥＤ照明器具の組立状態を示す断面図である。図４に示すように、取付ガイド１３を孔部１ｃに挿入することでガイドされたＬＥＤモジュール１を接続器１０に対して押し上げ、給電端子部１１を接続端子２に接触させる。この際、ガイド凸部３ｂとガイド凹部１ｂを嵌合させることで、給電端子部１１と接続端子２が位置決めされ接続状態が安定する。この後、レンズ７と器具カバー８を器具本体３に取付ける。
【００２２】
以上のようにこの実施の形態によれば、ＬＥＤモジュール１を交換可能であり、かつ照明器具の厚みを薄くすることができる。また、ＬＥＤモジュール１の交換取付時に強く押し付けられても、その力の方向に給電端子部１１が接触しないようにできるので給電端子部１１や接続端子２へは直接的に力が伝わらず変形や接触不良等の恐れが低い。また、給電端子部１１をＬＥＤモジュール１の側面に設けることで、ＬＥＤモジュール１の挿入時にガイド機能にもなる。
【００２３】
また、ＬＥＤモジュール１を円形とすることでモジュール１と器具本体３の嵌合状態が良くなる。また、モジュール１の片側よりによる接触状態の悪化を軽減でき、がたつきが小さくなる。図５はＬＥＤモジュールを円形と方形にした場合の説明図である。図５において、１は本発明の円形のＬＥＤモジュール、３はその器具本体、１′は比較のための方形のＬＥＤモジュール、３′はその器具本体、ｄは嵌合のためのクリアランスである。図５（ａ）の状態から、ＬＥＤモジュール１，１′が上方向にずれると（ｂ）の状態になり、さらに右方向にずれると（ｃ）の状態になる。この場合、円形のＬＥＤモジュール１では先の上方向のずれが解消されるが、方形のＬＥＤモジュール１′では上方向にも右方向にもずれたままである。このように、チップ搭載面を正面に見て、方形のＬＥＤモジュール１′は上下、左右の２方向にずれ、円形のＬＥＤモジュール１は上下のずれと左右のずれは互いに打ち消し合う関係である。
【００２４】
図６はこの発明の第１の実施の形態の変形例のＬＥＤ照明器具の断面図である。図６に示すように、第１の実施の形態の構成において、給電端子部１１の側面を傾斜させることで、接続状態で接続端子２が弾性変形してその復元力で接触状態が確実になる。
【００２５】
この発明の第２の実施の形態を図７および図８に基づいて説明する。図７はこの発明の第２の実施の形態のＬＥＤ照明器具の分解斜視図である。
【００２６】
図７に示すように、この実施の形態では、給電端子部１１はＬＥＤモジュール１の平面範囲内に開口した孔部１ｄの内側面に設けた。一方、接続端子２は給電端子部１１に接触可能なように接続器１０の中央寄りに配置されている。また、接続器１０の両端にＬＥＤモジュール１の取付ガイド１３が設けてある。この取付ガイド１３の係止部１３ａはＬＥＤモジュール１の基板１ａの端縁に係止する。なお、第１の実施の形態と同一部材には同一符号を付す。
【００２７】
上記構成のＬＥＤ照明器具の組立状態について説明する。図８はこの発明の第２の実施の形態のＬＥＤ照明器具の組立状態を示す断面図である。図８に示すように、接続端子２を孔部１ｄに挿入し取付ガイド１３でガイドされたＬＥＤモジュール１を接続器１０に対して押し上げ、給電端子部１１を接続端子２に接触させる。
【００２８】
以上のようにこの実施の形態によれば、接続端子２はＬＥＤモジュール１の範囲内に形成できコンパクトな器具が実現できる。なお、孔部１ｄは貫通していなくてもよい。その他の効果は、第１の実施の形態と同様である。
【００２９】
この発明の第３の実施の形態を図９ないし図１１に基づいて説明する。図９はこの発明の第３の実施の形態のＬＥＤ照明器具の分解斜視図である。
【００３０】
図９に示すように、この実施の形態では、給電端子部１５はＬＥＤモジュール１の側面よりピン状に突出してその周囲のいずれかの方向から接続可能とした。この場合、ＬＥＤモジュール１の外側面の切欠いた部分に給電端子部１５を突設している。一方、接続端子１６は給電端子部１５を挟着できるように２枚の導電板からなり、接続器１０の両端に配置されている。なお、第１の実施の形態と同一部材には同一符号を付す。
【００３１】
上記構成のＬＥＤ照明器具の組立状態について説明する。図１０はこの発明の第３の実施の形態のＬＥＤ照明器具の組立状態を示す断面図、図１１はその接続構造を示すＡ方向矢視図である。図１０および図１１に示すように、取付ガイド１３を孔部１ｃに挿入することでガイドされたＬＥＤモジュール１を接続器１０に対して押し上げ、給電端子部１５を接続端子１６の２枚の導電板間に入れて接触させる。
【００３２】
以上のようにこの実施の形態によれば、接続時の装着方向を問わず、ＬＥＤモジュール１と接続端子２の位置関係は上下どちらでもかまわない。また、器具が複数形態あっても１つのＬＥＤモジュールで対応可能である。その他の効果は、第１の実施の形態と同様である。なお、この実施の形態の給電端子部１５と接続端子１６を第２の実施の形態に適用してもよい。
【００３３】
この発明の第４の実施の形態を図１２および図１３に基づいて説明する。図１２はこの発明の第４の実施の形態のＬＥＤ照明器具の分解斜視図、図１３はその組立状態の断面図である。
【００３４】
図１２および図１３に示すように、この実施の形態では、ＬＥＤモジュール１を保持すると同時にＬＥＤ供給電源部５と電気的に接続機能を有した外郭部材１７を備え、給電端子部１１は外郭部材１７と接続される。この場合、外郭部材１７はレンズであり、接続機能として導通部材１８を有する。この導通部材１８は、接続端子２と給電端子部１１を接続できるように外郭部材１７の上部の端縁にＬ形に形成されている。また、外郭部材１７の上部にガイド凹部１７ａが形成され、器具本体３のガイド凸部３ｂに嵌合することで導通部材１８の接続状態が保持されるように位置決めされる。また、第１の実施の形態と比較してＬＥＤモジュール１の径が小さく、装着状態で給電端子部１１が接続端子２から離れるように配置される。なお、ＬＥＤモジュール１の径を変えずに、接続端子２の間隔を広げてもよい。
【００３５】
上記構成のＬＥＤ照明器具の組立時には、取付ガイド１３を孔部１ｃに挿入することでガイドされたＬＥＤモジュール１を接続器１０に対して押し上げる。この後、外郭部材１７をガイド凹部１７ａとガイド凸部３ｂが嵌合するように器具本体３に取り付けることで、接続端子２、導通部材１８および給電端子部１１が導通状態となる。
【００３６】
以上のようにこの実施の形態によれば、外郭部材１７を取り付けた後に電気的に接続され、ＬＥＤモジュール取り付け時の感電等の恐れがない。その他の構成効果は、第１の実施の形態と同様である。なお、外郭部材１７はレンズでなくてもよい。また、この実施の形態を第１〜３の実施の形態に適用してもよい。
【００３７】
この発明の第５の実施の形態を図１４ないし図１６に基づいて説明する。図１４はこの発明の第５の実施の形態のＬＥＤ照明器具の分解斜視図、図１５はその組立状態の断面図である。
【００３８】
図１４および図１５に示すように、この実施の形態では、ＬＥＤモジュール１を中心軸周りに回転操作することにより給電端子部２１が電気的に接続される。この場合、ＬＥＤモジュール１の対向する給電端子部２１に隣接しモジュール中心を挟んで対向する位置に案内部１ｅが形成されている。この案内部１ｅと給電端子部２１は凹形に形成され、これらと係合するように接続端子２２の導電板に凸部２２ａが形成される。また、ガイド凹部１ｂの幅を広くしてＬＥＤモジュール１の回転操作を可能としている。
【００３９】
上記構成のＬＥＤ照明器具の組立時には、取付ガイド１３を孔部１ｃに挿入することでガイドされたＬＥＤモジュール１を接続器１０に対して押し上げる。このとき、図１６（ａ）に示すように、案内部１ｅと接続端子２２を係合させる。次に（ｂ）に示すように、ＬＥＤモジュール１をＢ方向に回転操作することにより給電端子部２１と接続端子２２を係合させることで接続状態となる。
【００４０】
以上のようにこの実施の形態によれば、押し上げ時および引っ張り取り外し時は簡単に操作可能である。また、ＬＥＤモジュール１は円形であるため、回転操作時のＬＥＤモジュール回転領域の半径を、チップ搭載面積が同じ方形ＬＥＤモジュール１′に比べ、小さくすることが可能である（図５参照）。（理論上８０％未満になる）つまり器具本体のＬＥＤモジュール収納部分を小さくできる。その他の構成効果は、第１の実施の形態と同様である。
【００４１】
この発明の第６の実施の形態を図１７および図１８に基づいて説明する。図１７はこの発明の第６の実施の形態のＬＥＤ照明器具の分解斜視図、図１８はその組立状態の断面図である。
【００４２】
図１７および図１８に示すように、この実施の形態では、ＬＥＤモジュール１を中心軸周りに回転操作することにより給電端子部２１が電気的に接続される。この場合、ＬＥＤモジュール１の外周側面に雄ねじ１ｆが形成されている。給電端子部２１は雄ねじ１ｆの一部または全周に設けてある。また、接続端子２２には雄ねじ１ｆに螺合する雌ねじ２２ｂが形成されている。また、取付ガイド１３の先端に係止部はなく、器具本体３のガイド凸部およびＬＥＤモジュール１のガイド凹部もない。
【００４３】
上記構成のＬＥＤ照明器具の組立時には、取付ガイド１３を孔部１ｃに挿入することでガイドされたＬＥＤモジュール１の雄ねじ１ｆを接続端子２２の雌ねじ２２ｂにねじ込むことで、給電端子部２１と接続端子２２が接続状態となる。
【００４４】
以上のようにこの実施の形態によれば、ＬＥＤモジュール１の給電端子部２１はねじ形状となっているので、締め付けにより十分な接触荷重を得られる。このため、低電流通電時も安定した接触信頼性を得ることができる。その他の構成効果は、第１の実施の形態と同様である。
【００４５】
この発明の第７の実施の形態を図１９に基づいて説明する。図１９はこの発明の第７の実施の形態のＬＥＤ照明器具の分解斜視図である。
【００４６】
図１９に示すように、この実施の形態では、ＬＥＤモジュール１を中心軸周りに回転操作することにより給電端子部２１が電気的に接続される。この場合、ＬＥＤモジュール１の中心の孔部内側面にねじを設けたねじ孔１ｇが形成されている。給電端子部２１はねじ孔１ｇの一部または全周に設けてある。また、接続端子２２は接続器１０の中央寄りに配置され、ねじ孔１ｇに螺合する雄ねじ２２ｃが形成されている。また、接続器１０に取付ガイドはなく、器具本体３のガイド凸部およびＬＥＤモジュール１のガイド凹部もない。
【００４７】
上記構成のＬＥＤ照明器具の組立時には、ＬＥＤモジュール１を回転させてねじ孔１ｇに接続端子２２の雄ねじ２２ｃをねじ込むことで、給電端子部２１と接続端子２２が接続状態となる。この実施の形態でも第６の実施の形態の同様の作用効果が得られる。
【００４８】
【発明の効果】
この発明の請求項１記載のＬＥＤ照明器具によれば、ＬＥＤモジュールを器具本体の開口に挿入する方向に沿って接続端子が設けられ、ＬＥＤモジュールの側面に、接続端子側に接続してＬＥＤ供給電源部よりＬＥＤモジュールへ給電する給電端子部を設けたので、ＬＥＤモジュールを交換可能であり、かつ照明器具の厚みを薄くすることができる。また、ＬＥＤモジュールの交換取付時に強く押し付けられても、その力の方向に給電端子部が接触しないようにできるので給電端子部や接続端子へは直接的に力が伝わらず変形や接触不良等の恐れが低い。また、給電端子部をＬＥＤモジュールの側面に設けることで、ＬＥＤモジュールの挿入時にガイド機能にもなる。
【００４９】
また、ＬＥＤモジュールを円形とすることでモジュールと器具本体の嵌合状態が良くなる。また、モジュールの片側よりによる接触状態の悪化を軽減でき、がたつきが小さくなる。
【００５０】
請求項２では、給電端子部はＬＥＤモジュール端部の外側面に設けたので、ＬＥＤモジュールが中途半端に傾いた取り付け時は接触しにくくなり、異常取付点灯状態になりにくく安全である。
【００５１】
請求項３では、給電端子部はＬＥＤモジュールの平面範囲内に開口した孔部の内側面に設けたので、接続端子はＬＥＤモジュールの範囲内に形成できコンパクトな器具が実現できる。
【００５２】
請求項４では、給電端子部はＬＥＤモジュールの側面よりピン状に突出してその周囲から接続可能としたので、接続時の装着方向を問わず、ＬＥＤモジュールと接続端子の位置関係は上下どちらでもかまわない。また、器具が複数形態あっても１つのＬＥＤモジュールで対応可能である。
【００５３】
請求項５では、ＬＥＤモジュールを保持すると同時にＬＥＤ供給電源部と接続端子を介して電気的に接続される機能を有した外郭部材を備え、給電端子部は前記外郭部材と接続されるので、外郭部材を取り付けた後に電気的に接続され、ＬＥＤモジュール取り付け時の感電等の恐れがない。
【００５４】
請求項６では、外郭部材はＬＥＤモジュールの前面に設けたレンズであるので、レンズを装着してはじめて通電する構造となる。また、レンズを利用することで外郭部材を別に設ける必要はない。
【００５５】
請求項７では、ＬＥＤモジュールを中心軸周りに回転操作することにより給電端子部が電気的に接続されるので、簡単で確実に操作可能である。また、ＬＥＤモジュールは円形であるため、回転操作時のＬＥＤモジュール回転領域の半径を、チップ搭載面積が同じ方形ＬＥＤモジュールに比べ、小さくすることが可能である。つまり器具本体のＬＥＤモジュール収納部分を小さくできる。

BACKGROUND OF THE INVENTION
The present invention relates to an LED lighting apparatus.
[0002]
[Prior art]
Lighting fixtures using LEDs have been developed with a small size and long life. However, until now, the development of lighting devices mainly using auxiliary lighting (footlights, etc.) using orange LEDs and indicator lights using red LEDs have been mainly used.
[0003]
In recent years, blue LEDs have been developed, and then white LEDs have also been developed. White light can be obtained with LEDs, and it has been used for spot lighting and the like. However, the white LED currently being developed has a high temperature of the LED that is trying to obtain a high light output, and the resin covering the bare chip of the LED is rapidly deteriorated and the light output is lowered. For this reason, in lighting fixtures using white LEDs, it is difficult to say that there is no maintenance of the LED portion, but currently there are no products in which the LED portion can be exchanged for lighting fixtures that are currently commercialized.
[0004]
[Problems to be solved by the invention]
In the luminaire using white LEDs as described above, since the LED light emitting part is integrally incorporated in the luminaire, the replacement work of the LED cannot be performed alone, and the luminaire must be replaced for each luminaire or by a dedicated contractor. This is inconvenient for general users.
[0005]
Further, for example, there is an illumination device using LEDs disclosed in Japanese Patent Application Laid-Open No. 2001-52504. In this luminaire, the LED light-emitting portion can be exchanged. However, since this is an example that can be attached to a conventional socket for a general lamp, the socket needs to be incorporated in the luminaire, and the thickness of the luminaire is reduced. There is a drawback that increases.
[0006]
Accordingly, an object of the present invention is to provide an LED lighting fixture that can obtain a thin fixture structure by modularizing an LED portion used in the lighting fixture to have an exchange structure.
