Description
光源は、一般に、光導体の厚さより大きい距離だけアウトカップリング手段から間隔を置いて配置される。例えば、光導体が数ミリメートルの厚さである場合、光源は、一般に、アウトカップリング手段から数センチメートル以上の間隔を置いて配置される。一般に、隣り合ったアウトカップリング手段は、この距離より大きい間隔を置いて配置され、隣り合った光源もそうである。光導体中をアウトカップリング手段の密度は、好ましくは、光源の密度以上である。
図面及び前述の説明において本発明を詳細に図示及び説明したが、このような図及び説明は、説明的なもの又は例示的なものとみなされるべきであり、限定するものとみなされるべきではない。即ち、本発明は、開示されている実施例に限定されない。
