Zusammenfassung:	To avoid illumination quality from being impaired by downsizing the illumination quality.SOLUTION: The luminaire includes a light source having a planar light emitting face 36 for emitting light, and a parabolic reflection surface 34 for controlling light from the light emitting face 36. The reflection surface 34 is arranged at a position where a focus FA of a paraboloid separates a predetermined distance LC from the light emitting face 36 along a designed optical axis KA, and it has a reflection film 70 provided on the surface for enhancing the reflection factor of predetermined-wavelength light and a plurality of concave facets 80 provided on the surface.SELECTED DRAWING: Figure 10 【課題】照明品質の小型化によって照明品質が損われることがないようにすること。【解決手段】光を放射する面状の発光面３６を有した光源と、前記発光面３６の光を制御する放物面の反射面３４と、を備えた照明器具であって、前記反射面３４は、前記放物面の焦点ＦＡが前記発光面３６から設計光軸ＫＡに沿って所定距離ＬＣだけ離間した位置に配置されており、所定波長の光の反射率を高める反射膜７０が表面に設けられており、複数の凹状ファセット８０が前記表面に設けられている。【選択図】図１０
