Abstract
【解決手段】発光ダイ・パッケージ10は、基板20、反射板40、およびレンズ50を含む。前記基板は、熱伝導性ではあるが電気的には絶縁性の材料から作られ、取り付けパッドにおいて外部電源を発光ダイオードに接続するための複数のトレースを有する。前記反射板は、基板に結合され、取り付けパッドを略囲む。前記レンズは、反射板に対して自由に動け、それを濡らし接着するカプセル材によって上げたり下げたりでき、LEDチップから最適距離に置かれる。レンズは、装置の性能に影響する化学物質の任意の光学的システムで被覆することができる。動作中にLEDから生成される熱は、LEDから基板(底部ヒート・シンクとして働く)および反射板(上部ヒート・シンクとして働く)の両者によってうばわれる。反射板は、LEDから光を所望の方向に向けるための1つの反射面42を含む。
