- 照明系であり:
対称軸の周りにおいて基本的な放射分布を有する光を放射するための光源と、
照射面の少なくとも一部分を実質的に均一の照射するように、前記光源からの光を再び方向付けるためのコリメータとを含み、前記の均一に照射された照射面の少なくとも一部分は、前記対称軸に実質的に平行に延び、前記コリメータは、前記光源からの光を受け取るための凹型入口窓を有し、前記照射面へ向けて光を方向付けるための少なくとも部分的に凹型の出口窓をさらに有し、該出口窓の凹型の部分は、前記光源によって放射される光を、前記照射面から離れる方向へ、そして該照射面へ向けて戻るように屈折させ、前記照射面の少なくとも一部分を実質的に均一に照射するように、前記基本的な放射分布の対称軸に関して非対称的である代替の放射分布を生成するために形作られている、照明系。 - 請求項1に記載の照明系であり、前記コリメータは、前記入口窓と前記出口窓との間に配置された縁壁を有し、該縁壁は、該入口窓と境界線縁との間において、さらなる対称軸の周りに実質的に対称的に配置され、該さらなる対称軸を通る断面において実質的に放物線状の形状を有している、照明系。
- 請求項2に記載の照明系であり、前記コリメータのさらなる対称軸及び前記放射分布の対称軸は、前記凹型入口窓の焦点で実質的に交差し、前記さらなる対称軸は、該放射分布の対称軸に関して傾斜角をなして傾いている、照明系。
- 請求項3に記載の照明系であり、前記さらなる対称軸は、前記対称軸に関して前記照射面へ向けて傾き、該さらなる対称軸と該対称軸との間の傾斜角αは、0.5度と10度の間の範囲にある、照明系。
- 請求項2乃至4のうちいずれか1項に記載の照明系であり、前記出口窓の第1部分は、該出口窓の実質的に平面の部分を有し、該第1部分は、第1平面と前記照射面との間に配置され、前記第1平面は、前記さらなる対称軸を通って延び、前記対称軸及び前記さらなる対称軸を取って延びる第2平面に実質的に垂直に配置され、前記照射面の反対側の第1平面の1つの側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、該出口窓の凹型部分を有する、照明系。
- 請求項2乃至5のうちいずれか1項に記載の照明系であり、前記出口窓は、前記対称軸及び前記さらなる対称軸を取って延びる第2平面に関して実質的に対称的である、照明系。
- 請求項1乃至6のうちいずれか1項に記載の照明系を有し、前記照射面を有する照明器具。
- 請求項7に記載の照明器具であり、複数の照明系を有し、各照明系が、光源、前記照射面の一部分を照射するためのコリメータを有し、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。
- 請求項8に記載の照明器具であり、前記複数の光源が、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、照明器具。
- 請求項7乃至9のうちいずれか1項に記載の照明器具であり、前記照射面の一部分が、前記コリメータに関して凹型に形作られた曲面である、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7乃至10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7乃至10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7乃至12のうちいずれか1項に記載の照明器具。
- 請求項1乃至6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7乃至13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。
- 請求項7乃至13のうちいずれか1項に記載の照明器具を背面照明系として有する、表示装置。
