Abstract
【解決手段】透明のプラスチックおよび燐光体添加剤を含む溶融液体を鋳型に充填し、この溶融液体を凝固させて、燐光体が内部に分散した透過型光学要素を作製することによって、透過型光学要素が製造される。透過型光学要素は、燐光体が内部に分散されている透明のプラスチックから作製されたシェルを含む。燐光体はシェルの中に均一および/または不均一に分散され得る。
【選択図】図1
Description
層、領域、または基板などの要素が、別の要素の「上に」あると言及されるとき、それは他の要素の上に直に存在してもよいし、または介在する要素が存在してもよいことが理解されよう。導電線の表面のような要素の一部が「外方(outer)」と言及される場合に、それは当該要素の他の部分よりも素子の外側に近接していることが理解されよう。さらには、本明細書では「下方」というような相対的な用語が、図に例示する基板または基層を基準にして、1つの層または領域が別の層または領域に対する関係を説明するために使用され得る。これらの用語は、図に示す配置に加えて、素子の異なる配置を包含しようとするものであることが理解されよう。最後に、「直に」という用語は、介在要素が存在しないことを意味する。
