Description
本発明は、LED照明システムの技術分野に関する。本発明は、特に、従来白熱光源で用いられている光パッケージに利用され、本発明を特にこれに関して説明する。当業者であれば、伝統的な電球型光パッケージ内にLED光源を用いることにより種々の利点、例えば耐久性の向上、光出力安定性の向上及びエネルギ節約の向上をもたらすことができる用途への本発明の利用可能性を理解されよう。
本発明は、新規なLED灯(ランプ)を提供する。
本発明の一特徴によれば、光源が開示される。光エンジンが、複数の波長のうちの1つを持つ光を発生させる。光エンジンは、プラットホーム及びプラットホーム上に設けられた少なくとも1つのLEDを有する。エンクロージャが、光エンジンの光発生領域を包囲している。口金が、熱エネルギを少なくとも1つのLEDが遠ざけて伝えるヒートシンクを有する。光エンジンは、ヒートシンクに取り付けられている。変換回路が、電力を光エンジンに供給する。
別の目的は、アダプタブル(適応可能)且つスケーラブル(拡大縮小可能)のLED灯設計が提供されることにある。
本発明は、種々のコンポーネント及びコンポーネントの配列、並びに種々の工程及び工程の配列の形態を取ることができる。図面は、好ましい実施形態を説明する目的にのみ作成されており、本発明を限定するものと解釈されてはならない。
図1及び図2を参照すると、照明システム10は、取り付けプラットホーム10上に位置決めされていて、光エンジン16を構成する1個以上のLED12を有している。リード線18,20が、LED12に給電するために設けられている。LED12は、UVから赤外までのスペクトルの光を放出する無機及び有機発光素子のうちの1つである。光学的性能、観察角及び強度レベルの変更は、LEDを種々のパターンで配置することにより達成される。照明システム10は、光カバー又はエンクロージャ22を有している。好ましくは、エンクロージャ22は、伝統的な電球形のエンクロージャである。エンクロージャ22は、特定の視覚的効果を生じさせるよう一様ではない光出力をもたらす特注のエンクロージャであるが、このようにするかどうかは任意である。エンクロージャ22は、球形、楕円形、円筒形、ドーム形、正方形、n個の側部を備え又は任意他の形状であってもよいことが想定されている。好ましくは、エンクロージャ22は、光に対して透明な又は半透明な材料又はこれらの組み合わせで作られる。エンクロージャ22の材料は、ガラス、プラスチック、アクリル樹脂、ポリカーボネート又は他の適当な材料から選択される。
口金24は、熱電冷却、ピエゾ合成ジェット、クー−パイプ(qu-pipe)、ピエゾファン、電気ファン又は動力を利用する他の冷却形態のうちの少なくとも1つを有するが、このようにするかどうかは任意である。
