Abstract
Description
しかし、こうしたバルブは、頻繁に故障し、高い保守コストをもたらし、バルブ内の水銀蒸気雰囲気が、廃棄時に環境問題を引き起こす可能性があるため、やはり問題を有する。
本発明の好ましい実施形態は図面に示される。
回路ディスク28は、12個の30°セグメント36を有し、1つのセグメント38は、分割され、回路相互接続点の役をする。これは、各回路ディスク28が、直列に接続された12個のLEDバルブ26を有することを可能にする。4個の回路ディスク28が、直列に接続されて、48個のLEDバルブのLEDクラスタが提供される。光出力を増加するために、いくつかのLEDクラスタが、並列に接続される。通常、2〜6個のこうしたクラスタが並列に接続される。光の拡散を改善するために、LEDクラスタは、交互に配置され、互いに積重ねられない。金属ディスク30および絶縁ディスク32は、積重ね体内に適切に設置され、全ての合わせ面上に、放熱化合物(thermal compound)が使用される。積重ね体は、絶縁保持ロッド34によって一緒にねじ込まれ、放熱キャップ14に取り付けられる。キャップ14は、いくつかの機能を果たし、重要な設計要素の1つである。
LEDアレイからの光についての発光スペクトルおよび分布は、LEDのタイプと光路とによるものである。好ましくは、CRIが85+の白色光を生成するのに、2つのタイプの5mmLEDが利用される。
