前記照射面に対向する第1平面の一の面上に配置された該出口窓の第2部分は、該照射面へ向けて光を屈折させるために、該少なくとも部分的に凸型の出口窓の凸型部分を有する、
照明系。 - 請求項3に記載の照明系であり、前記少なくとも部分的に凸型の出口窓は、前記ランバート放射分布の対称軸及び前記さらなる対称軸と交差してさらに延びる第2平面に対して実質的に対称的で、かつ、前記第1面に対して垂直に配置される、照明系。
- 請求項1乃至4のうちいずれか1項に記載の照明系を有する照明器具であり、前記照射面を有する、照明器具。
- 請求項1乃至4のうちいずれか1項に記載の複数の照明系を有する照明器具であり、前記複数の照明系は、該照射面を実質的に均一に照射するように一緒に配置されている、照明器具。
- 前記複数の照明系の複数の光源が、光源の列において配置され、
個々の前記照明系によって照射される個別の部分が部分的に重なり、
該個々の照明系の光の分布は、前記照射面の全域で実質的に均一の光分布を生成するように配置されている、
請求項6に記載の照明器具。 - 前記照射面の一部分が、前記コリメータに対して凹型に形作られた曲面である、請求項5乃至7のうちいずれか1項に記載の照明器具。
- 前記照射面は、前記照明器具の光放射窓の実質的に反対側に配置された反射面である、請求項5乃至8のうちいずれか1項に記載の照明器具。
- 前記照射面を有する光放射窓を有する、請求項5乃至8のうちいずれか1項に記載の照明器具。
- 前記照射面及び/又は光放射窓は、前記光源によって放射される光の少なくとも一部分を異なる色の光に変換するための発光体を有する、請求項5乃至10のうちいずれか1項に記載の照明器具。
- 請求項1乃至4のうちいずれか1項に記載の照明系において使用するための、及び/又は請求項5乃至11のうちいずれか1項に記載の照明器具において使用するための、コリメータ。
