Description
図1は、本発明の実施形態による照明器10を模式的に示した側面図である。照明器10は、ランプ12と、光変調要素16のアレイを備えている空間光変調器14と、データを受けて、それに従って変調器14を制御するための制御装置18と、レンズ20とを備えている。
ランプ12は、例えば、発光ダイオードの光源で良い。
Claims (14)
- 照明器であって、
それぞれが選択的に、光の方向を変更せずに入射光を伝達、または入射光の方向を変更するように構成されている要素のアレイを備えている空間光変調器と、 前記変調器を照明するように配置されたランプと、
前記変調器からの変更されていない光を、照明面へと導くレンズと、
前記変調器によって方向を変更された実質的にすべての光を、照明面に向けて送る手段と、を備えている、
ことを特徴とする照明器。 - 前記送り手段は、前記変調器によって方向を変更された光を、照明面に向けて反射するように構成されている反射鏡を備えている、
請求項1に記載の照明器。 - 反射鏡は、テーパ管として形成され、変調器は管の狭い端に配置され、管の広い端は照明面へと向けられ、管の横断面は、好ましくは本質的に、変調器の形状に合致している、
請求項2に記載の照明器。 - 前記送り手段は、セグメント化されたレンズを備え、前記光を導くレンズは、セグメント化されたレンズの一部分によって形成されている、
請求項1ないし3のいずれか1項に記載の照明器。 - 前記セグメント化されたレンズは、中央の第1の部分と、周辺の第2の部分とを有し、前記第1の部分は、前記第2の部分と異なる焦点距離及び/又は光軸を有している、
請求項4に記載の照明器。 - 前記光を導くレンズは、前記中央の第1の部分によって形成されている、
請求項5に記載の照明器。 - 前記ランプと変調器との間に配置されている第2のレンズをさらに備えている、

請求項7に記載の照明器。 - 変調器と前記光を導くレンズとの間に配置されている、非吸収絞りをさらに備えている、
請求項1ないし8のいずれか1項に記載の照明器。 - 前記非吸収絞りは、好ましくは照明面に向けた前方へ、入射光の方向を変更するように構成されている、
請求項9に記載の照明器。 - 非吸収絞りは開口部を有し、前記ランプからの光は、前記開口部に焦点が合わせられている、
請求項9又は10に記載の照明器。 - 前記非吸収絞りは、局所的に調整可能な光伝達特性を有している、
請求項9又は10に記載の照明器。 - 入射光の方向は、散乱、屈折、及び回折のうちのひとつによって、変調器で変更される、
請求項1に記載の照明器。 - 前記変調器は、液晶セルである、
請求項1に記載の照明器。
