Description
この代わりに、ランプアセンブリに対する給電を可能にするためには、そのランプアセンブリの二次コイルが一次コイルに隣接して配置されるだけでよい。第2に、電気コネクタの排除は、さらに、従来の電気コネクタに関連している問題点を取り除くことによって、そのシステムの信頼性を向上させる。例えば、従来の電気コネクタは腐食と摩耗の悪影響を受ける。これらの問題は、環境条件のせいで電気コネクタが湿気にさらされる可能性がある屋外設置の場合に特に深刻である。さらに、使用の反復につれて、電気コネクタが摩耗して最終的には故障する。第3に、誘導結合型ランプは、本来的に、ランプアセンブリにおける電気的な事故の発生リスクを低減させる。上述したように、このランプアセンブリは電源から電気的に分離している。すべての電力が電源からランプアセンブリに誘導によって送られなければならない。ランプアセンブリに対して誘導によって送られることが可能な電力の量には本来的な制限があるので、ランプアセンブリにおける電力の量は制限されており、電気的な事故のリスクは低減させられる。
この効率の問題は、より高電力の照明用途の場合に悪化させられる。さらに、既存のランプ回路は、なんらかの適切なレベルの効率を実現するためには、一次コイルと二次コイルとの正確な位置合せを必要とする。このことは、より正確な公差を必要とし、および、ランプアセンブリとランプ全体との形状構成とレイアウトとを制限する。
このプリント基板は、誘導結合の動作のために必要とされる様々な電気構成要素を含む。
別個のシェル構成要素とレンズ構成要素とが、ランプとプリント基板と二次コイルとの周囲に漏洩防止容器を形成するように一体状に封着される。このシェルは、特に、二次コイルを受け入れるように、および、一次コイルを収容するソケットと嵌合するように形成されている。密封容器が環境条件に対する保護の改善を実現するが、この密封容器は大きくて扱いにくく、レンズの方向における光の送出だけしか可能にしない。
この第2のスリーブとランプスリーブとの間に画定されている隙間が、所望のレベルの熱伝導または断熱を実現するように真空にされているか機能性ガスで充填されていることが好ましい。
上述したように、PL−Sタイプの38W UVランプが、環境からランプ回路12を保護するためにランプ回路12を中に封入するための外側スリーブ70を含むことが好ましい(図1と図2を参照されたい)。外側スリーブ70が主本体90とキャップ92とを含むことが好ましい。主本体90は、開いた端部と閉じた端部とを有する概ね円筒形の管である。ランプ回路12が主本体90内に取り付けられた後に、キャップ92が、ランプ回路12を中に完全に封じ込めるために、主本体90の開いた端部の上に封着される。ランプ回路12は、一般的に、二次コイル14と、コンデンサ16と、ランプ18とを含む。後述するように、ランプ回路12は、さらにスタータ35も含んでよい(図2を参照されたい)。ランプ18は、協働してチャンバ28を画定するように相互連結されている2つの互いに平行な脚部72a、72bを有する石英スリーブを有する概ね従来のPL−Sタイプのランプである。チャンバ28は部分真空にされており、および、水銀蒸気のような所望の放電ガスを収容する。ステム32a、32bが各脚部72a、72bの基部に配置されている。1対の従来通りまたは特別設計の電極26a、26bが、チャンバ28内に配置されており、この電極はステム32a、32bの各々の上に1つずつ取り付けられている。この実施形態では、外側スリーブ70が、UV光の効率的な通過を可能にするために石英で作られていることが好ましい。非UV用途では、この外側スリーブは、ランプによって発生させられる熱とランプの動作環境とに部分的に基づいて、ガラス、テフロン、または、プラスチックで製造されてもよい。例えば、代案の外側スリーブが、密封された両端部(図示されていない)を有する一定の長さのテフロン管材料から製造されることが可能である。このテフロン管材料は、ランプアセンブリの残り部分の上に嵌合させられることが可能であり、および、テフロンスリーブを密閉するために、その両端部が圧着されるか、または、別の形で封止されることが可能である。このテフロン管材料の各端部がその管材料自体の上に折り返されているか、または、熱と圧力とを使用して圧着されていることが好ましい。
次に、ランプ回路12を、上述のPL−Sタイプの38W UVランプ(図1と図2を参照されたい)に関連付けて説明する。上述したように、ランプ回路12は、一般的に、ランプ18と、二次コイル14と、コンデンサ16とを含む。ランプ回路12の略図が図3に示されている。この実施形態では、ランプ回路12は、小直径ワイヤ22のコイルの形であることが好ましい単一の二次コイル14を含む。この二次コイル14の明確な特徴は、一次コイル(図示されていない)と負荷(例えばランプ)とに応じて用途毎に異なるだろう。ワイヤ22は、電力設定と熱散逸とに応じて従来の磁石ワイヤまたはLITZワイヤであることが好ましい。このワイヤは、基部50の外周部の環状凹み80の中に巻かれることが好ましく、このことが中空の磁心を二次コイル14に与える。必要に応じて、中空の磁心24が他の従来の磁心によって置き換えられることが可能である。ワイヤのタイプ、ワイヤの巻回数、および、磁心の直径(および、したがって、ワイヤの巻回の直径)は、一次コイルの特性とランプ18の負荷とのような様々な要因に応じて、用途毎に変化するだろう。二次コイル14のインダクタンスが、供給電力における動作周波数と負荷(すなわちランプ)のインピーダンスとに応じて選択される。さらに明確に述べると、二次コイル14のインダクタンスは次式によって決定される。
ランプアセンブリの形状構成は、ランプのタイプとそれに関連した電力要件とに主として応じて用途毎に大きく変化することがあり得る。本発明は、様々な既存の照明システムと共に使用することを可能にするために容易に変更されることが可能である。次の代案の実施形態が、様々な用途に適合化された様々な代案の具体例を示す。これらの代案の実施形態は、本発明の広範囲な適応性を例示することを意図されており、網羅的であることは意図されていない。
しかし、基部150は、様々な異なるソケットに対してランプアセンブリ110が機械的に連結することを可能にするために様々な異なる形状構成を呈することが可能である。例えば、この基部は外側にねじ山が付けられていてもよい。図に示されているように、ランプアセンブリ110が感知磁石160も含むことが好ましい。この感知磁石160は、基部150の底部内の対応する保持壁162の中に嵌合させられてもよい。上述したように、感知磁石160は、リードスイッチのような磁気駆動スイッチと共に、ランプアセンブリ110の存在を一次コイルまたは制御回路に通知する機能を果たす。このことが、ランプアセンブリ110が所定の位置にある時にだけ一次コイルが給電されることを可能にする。図5に示されているように、白熱灯アセンブリ110′は従来の汎用口金との組合せで動作するように構成されることが可能である。この実施形態では、基部150′は、従来の汎用口金ランプソケット(図示されていない)内の適合するスロット(matching slot)と噛み合うように構成されている1対の装着ピン156a、156bを含む。
この実施形態では、導線498a、498bが2つの二次コイル414a、414bの間を延びることが必要とされている。導線498a、498bがランプスリーブ452内に収容されていることが好ましい。代案としては、磁気スイッチ434a、434b、または、他の遠隔駆動スイッチが、従来のスタータの代わりに使用される。図12に示されているように、ランプアセンブリ410′は、各二次コイル414a、414b′とその対応するフィラメントすなわち電極436a、436b′との間に直列に取り付けられている別のスイッチ434a、434bを含む。スイッチ434a、434bを閉じることによって、各二次コイル414a、414b′からの電力がその対応するフィラメントに直接供給される。この実施形態では、単一の導線498′だけが二次コイル414a、414b′の間を延びることが必要である。コンデンサ416′が導線498′に沿って直列に接続されている。
こうした用途では、2つのコンデンサの値の間の比率がその2つの二次コイルの間の電力比率に等しくなければならない。
二次コイル514a、514bの各々は、電極536a、536bと、コンデンサ516a、516bと、磁気駆動スタータスイッチ534a、534bとに直列に接続されている。各コンデンサ516a、516bの値は、図13の実施形態に関連して上述されたように選択される。このランプアセンブリ510は、さらに、感知磁石560を含んでもよい。
独占的な所有権すなわち特権が請求されている本発明の実施形態が、特許請求の範囲で定義されている。
