Description
すなわち、本発明においては、レンズの光学活性面上に波形形状に形成された微細構造を有し、かつ該微細構造上に波形を呈するミクロ構造が形成された光学レンズが提供される。つまり、上記レンズ面が、波形形状の2つの構造が互いに重ね合わされ、他の技術分野において公知の用語を用いればミクロ構造が微細構造を変調するように、ある程度の形状化が与えられる。かかる光学レンズを用いることにより、光源の明域暗域間の鮮明な境界部分が明域暗域間の穏やかな遷移部分をもって投影される。前記遷移部分の鮮明さあるいは穏やかさは、上記提案された構造を用いることにより、目的に適った方式で変化あるいは調節させることが可能である。
なお、前記両構造はレンズの片面あるいは両面へ設けることが可能である。
前記微細構造の波の荒さの特に好ましい範囲は1〜10μmである。
他方において前記ミクロ構造の波の荒さは、好ましくは0.1〜2.5μmの範囲である。
前記両構造はレンズ材中に永久的に形成される。レンズが非球面側を有して具現化されている場合は、前記両構造は特に好ましくはレンズの非球面側に設けられる。
なお、以下の説明においては、同一符号は同一素子を表わす。
Claims (5)
- 波形微細構造(2)と波形ミクロ構造(3)を備えた前照灯用レンズ(1)において、前記レンズ(1)の光軸から、レンズの光学活性面上を半径方向外側に向かって、各波頂と各波底とが同心円を画くように延びている前記波形微細構造(2)と、光軸から各波頂と各波底が半径方向に延びた前記波形ミクロ構造(3)の2つの構造が互いに重ね合わされた光学活性面を有し、前記波形微細構造(2)は1〜10μmの波の荒さであり、前記形状ミクロ構造(3)は0.1〜2.5μmの波の荒さであるような波形微細構造と波形ミクロ構造を備えた前照灯用レンズ。
- 前記微細構造(2)及びミクロ構造(3)がレンズ(1)の光軸を中心として同心円状に延びる一表面部分(4)中に形成されていることを特徴とする請求項1に記載の光学レンズ。
- 前記表面部分(4)がレンズ(1)の非球面側上において光軸に対し同心状に構成されていることを特徴とする請求項2項記載の光学レンズ。
- 前記微細構造(2)の波の荒さがレンズの光軸からレンズ周辺へ向かって減少していることを特徴とする請求項1項ないし3項のいずれかに記載の光学レンズ。
- レンズ(1)の微細構造(2)の波の荒さがレンズ(1)の周辺方向へ行くにつれ減少していることを特徴とする請求項3項記載の光学レンズ。
