Abstract
Description
光拡散性ファイバにおいて、散乱の主要成分は、5°〜10°に近い、小角度にある(図1Bの角度170または図2Bの角度270を参照のこと)。したがって、(一般には被覆内の)発光体からの黄色光が入射青色光と混合される場合、得られる色は視角に依存する。これは、発光体の発光による黄色光は(角度170に依存せず)角度空間においてほとんど一様であるが、青色光は(散乱後でさえ)強い小角度成分を有するためである。これらの2つの事実の結果、小視角では青色が支配的であって、90°より大きい角度ではほとんどが黄色である、色の非対称性が生じる。実施形態は、光拡散性ファイバにおける散乱光を一様化して視角の関数としての色が一様な光を提供することにより、これらの問題を解決する。
別の態様は、450nmより短波長のような、ファイバクラッド層が強い吸収を有する波長において光取出し効率が高い光拡散性ファイバを含む。UV波長へのLDFの使用は、光反応器、水/空気純化、アクリレート重合及び関連分野に対する応用の範囲を拡大するに役立つ。光反応に用いられる(すなわち、約400nmより短い)波長が一般に望まれ、一般的なUV硬化性ポリマーは光開始剤に必要であることからこの波長において強い吸収を有する。本明細書の実施形態は、通常は高屈折率二次被覆に止められる、LDFからの光の取出し効率を向上させる。この波長におけるLDFの注目に値する用法の1つは、UV材料を硬化させるためのアクセスが、離れていて、狭く、困難である場所に光を入れることができることであろう。
