Description
どの照明解決策も全ての機器構成を最適に満たすことはできないが、本発明の一実施形態によるLEDライトエンジンは、光硬化に望ましい全ての波長にわたる全ての性能指数に基づいて、表Iに列挙される伝統的技術に対応する又はこれを凌ぐように、最良の固体技術を組み合せる。本発明の一実施形態において、LEDライトエンジンは、光硬化に適した波長において、10W/cm2までの強度を有する、500mW/カラーを超える光を放射することができる。本発明は光生成のための高性能な代案を提供する。このLEDライトエンジンの能力が、表II内で強調されている。LEDライトエンジンがもたらす高性能の照明は、照明構成要素の集合全体に取って代わるように設計された単一のコンパクトなユニットの形で具体化される。光源、励起フィルタ、マルチカラー切り換え能力及び高速パルシングが、設置面積の小さい1つの箱内に含まれるので、外部の光学系又は機構は必要でない。
図2A−図2Gは、図1AのLEDライトエンジンシステム110のLEDライトエンジン100の図を示す。図2A及び図2Bは、LEDライトエンジン100の外観図を示す。図2Cは、カバーを取り除いたLEDライトエンジン100の斜視図を示す。図2D及び図2Eは、カバーを取り除いたLEDライトエンジン100の側面図を示す。図2Fは、LEDライトエンジン100の底面図を示す。
図3A−図3Cは、LEDモジュール241及びコリメータ241cの図を示す。LEDモジュール242及び243は同じ設計を有するが、LEDモジュール241、242及び243の各々は、LEDモジュール241、242及び243のうちの他のものとは異なる波長の光を放射するLEDを含むことが好ましい。図3Aは、LEDモジュール241、コリメータ241c、及び関連した二色性ミラー244の斜視図を示す。図3Aに示すように、LEDモジュール241は、プラットフォーム230(図2C−図2E参照)に取り付けられるように適合されたベース300を含む。コリメータ241cは、ベース300に取り付けられる。
図4A−図4Dは、LEDライトエンジン100(図2C及び2E参照)の出力光学系256を示す。図4Aに示すように、出力光学系256は、LEDライトエンジン100の全ての光源から、コリメートされた結合光ビーム254を受け取り、結合ビーム254を合焦し、それをライトガイド102の開口部428内に向ける。アダプタ108がライトガイド102を出力光学系256に接続し、ライトガイドの開口部428が正しく位置決めされて合焦した結合光ビーム254を受け取るように、ライトガイド102を位置決めする。出力光学系256は、ライトガイド102を前板214内の開口部を通して出力光学系256に接続できるように、前板214に対して位置決めされる。
