Abstract

　簡易な構成で、出射される照明光の光量の変動を防止し、明るい照明光を出射する。周方向に等間隔に配列された複数の光源（２）と、該光源（２）からの照明光を導光する第１の導光部材（３ｃ）と、これを軸線回りに回転させる駆動装置（３ｄ）と、第１の導光部材（３ｃ）の出射端（３ａ）から出射された照明光を入射させて導光する、光源（２）に対して固定された第２の導光部材（４）とを備え、第１の導光部材（３ｃ）の出射端（３ａ）および第２の導光部材（４）の入射端（４ａ）が軸線（Ｃ）を重心とする略正多角形状の開口形状を有し、第２の導光部材（４）が、光源（２）に対して、出射端（３ａ）からの照明光の光量が最小値となる第１の導光部材（３ｃ）の角度位置と、出射端（３ａ）の開口形状と入射端（４ａ）の開口形状との重複面積が最小値となる第１の導光部材（３ｃ）の角度位置とが一致しないような位相関係で配置された照明装置（１）を提供する。
