Claims (5)
- 電源手段に電気的に接続した少なくとも1つのランプホルダー(603)(703)をその中に設置したランプシェード本体(601)(701)と、
前記少なくとも1つのランプホルダーに設置され、光を発光する少なくとも1つの発光装置(604)(704)と、
前記少なくとも1つの発光装置を通過させるための少なくとも1つの貫通孔を含むライトコンデンサー(608)(708)と、
前記ランプシェード本体の内部に固定して取り付けられ、複数のファセット(105)(面)でできている湾曲型表面を含む湾曲型反射板(605)(705)であって、各前記ファセットのサイズおよび水平線に対する各前記ファセット角度が光反射の原理および入射光と所定の照明ブロックに向けて各前記ファセットによる反射光との間の予想夾角に従って計算される、湾曲型反射板と、
前記ランプシェード本体の照明側において取り付けられた光透過性板(606)(706)と、
前記ランプシェード本体内の前記光透過性板の内側に固定して取り付けられ、前記少なくとも1つの発光装置に狙いをつけた頂点を有する反射コーン(607)(707)と、
を含み、前記ライトコンデンサーが、前記少なくとも1つの発光装置からの放射光を前記反射コーンに集光して、前記反射コーンが集光した光を前記反射板上へ反射できるようにすることによって、前記反射板が前記反射コーンから所定の照明領域へ向けての偏向光を反射して均一な光分布を達成し、前記反射コーンが前記少なくとも1つの発光装置によって放射した光線の一部を複数反射により所定の照明領域に入射させる、省エネ型ランプシェードであって、
前記光透過性板が、複数の臨界角およびその少なくとも片側に光学格子を備え、前記光学格子の格子空間、角度、仕様および形状は、前記臨界角より大きい入射角で前記光透過性板上に前記少なくとも1つの発光装置により放射された光線を制御して、反射されるようにする光学的臨界角の原理、および前記臨界角より小さい入射角で前記光透過性板に入射する光線を制御して、前記光透過性板を通過するようにする光学的臨界角の原理に従って決定される、ことを特徴とする省エネ型ランプシェード。 - 前記光透過性板が、複数の同心的に配置された環状線を含む円形格子でできている、請求項1に記載の省エネ型ランプシェード。
- 前記光透過性板が、直線の格子を含む矩形格子板でできている、請求項1に記載の省エネ型ランプシェード。
- 前記ライトコンデンサーが、放物曲線を示すように構成される、請求項1に記載の省エネ型ランプシェード。
- 前記ライトコンデンサーが、部分的に楕円曲線を示すように構成される、請求項1に記載の省エネ型ランプシェード。
