Description
(a)第1主面が、光が材料に入射する角度によって変化する反射率および透過率を有する材料を備え、
(b)第2の主面が、任意の角度で面に入射する可視光の少なくとも85%の全反射率を有する狭散乱反射材料を備え、
これにより、共振器内部からの光が、第1の主面にわたって実質的に一様に放射されるライトガイドを提供する。
前主面5を除くライトガイド1のハウジング3は、任意の適切な材料、たとえばPVC(ポリ塩化ビニル)による一体真空成形構成であってよい。別法として、ハウジングは、任意の適切な方法で互いに固定されたそれぞれがハウジングの一面を提供するたとえばアクリル材料のいくつかの部分から形成されてよい。ハウジングは、約60×60×4.5cmである。
ライトガイドのハウジング3がより大きく、寸法が約120×180×6cmである点を除き、実施例Iに記載したものと同様のライトガイドモジュールが構成された。さらに、ハウジング3の細幅面7における光学シート材料15が削除され、照明管11用のハウジング25が図6に概略的に示されたハウジング40によって構成された。図6は、ライトガイドハウジング3の細幅面7に対するハウジングの配置も示している。照明管ハウジング40は、ライトガイドハウジング3とは分離し、(参照符号41によって図6に示されている)照明管の長さに沿って延在し、ライトガイドハウジングの側面7の長さに沿って延在する。ハウジング40は、照明管41の後に位置する後方部分42と、後方部分42の各前縁44からライトガイドハウジング3に向かって延在する発散平面43と、を具備している。発散面43は、照明管41からの光をハウジング40から出射することができる出口開口部を画定する。ハウジングの後方部分42は、照明管41を部分的に包囲するが、照明管41から離隔し、照明管41が図に示されたように前縁44のわずか前方にまで延在することができるように形成されている。図6において、後方部分42は、湾曲しているように示されているが、代わりに、曲線に近い一連の平たい部分を備えていてもよい。ハウジング40(すなわち後方部分42および側面43)の内面は、たとえば、上述の「VM2000 ラディエント・ミラー・フィルム(Radiant Mirror Film)」などの高効率の鏡面反射材料で覆われる。
Claims (3)
- 略平行な第1主面及び第2主面を有するライトガイド光共振器を形成するハウジングと、可視光を前記第1主面と前記第2主面との間に案内されるように一面から前記共振器内に向けるように配置された少なくとも1つの光源と、を備え、
(a)前記第1主面は、光が材料に入射する角度によって変化する反射率及び透過率を有する材料を備え、
(b)前記第2主面は、任意の角度で面に入射する可視光に対して少なくとも85%の全反射率を有する狭拡散反射材料を備え、
これにより、前記共振器内からの光が前記第1主面にわたって実質的に一様に放射されることを特徴とするライトガイド。 - 前記第2主面が、光学フィルム又はシート金属を備えることを特徴とする、請求項1記載のライトガイド。
- 前記第1主面が、透明材料の平面シートの一面を備えることを特徴とする、請求項1又は2のいずれかに記載のライトガイド。
