To provide a luminaire capable of efficiently using light of a light source.SOLUTION: A luminaire 1 comprises: a light source 4; a light deflector 5 which reflects light from the light source 4 by an MEMS mirror 5a to make a scan within a predetermined angular range; a phosphor plate 8 which has a light distribution formation region 8a and converts the wavelength of the scanning light; a projection lens 10 which controls light from the phosphor plate 8 to project a light distribution pattern; and a reflector mirror 7 which is so arranged that light from the light deflector 5 impinges on the phosphor plate 8. The reflector mirror 7 has a plurality of curved-surface regions R1-R3 which are differently inclined and differ in curved-surface shape from one another, and light reflected by the plurality of curved-surface regions R1-R3 respectively radiates the light distribution formation region 8a.SELECTED DRAWING: Figure 1 【課題】光源の光を効率的に利用することができる照明装置を提供する。【解決手段】本発明の照明装置１は、光源４と、光源４からの光をＭＥＭＳミラー５ａにより所定の角度範囲に反射して走査する光偏向器５と、配光形成領域８ａを有し、走査された光の波長を変換する蛍光体プレート８と、蛍光体プレート８からの光を制御して、配光パターンを投影する投影レンズ１０と、光偏向器５からの光が蛍光体プレート８に入射するように配設されたリフレクタミラー７を備えている。リフレクタミラー７は、傾斜が互いに異なり、曲面形状も互いに異なる複数の曲面領域Ｒ１〜Ｒ３を有し、当該複数の曲面領域Ｒ１〜Ｒ３の各々によって反射された光は、配光形成領域８ａを照射する。【選択図】図１
