To provide a luminaire for preventing laser light from being emitted directly to the outside through a projection lens even when defect or breakage occurs in a wavelength conversion member.SOLUTION: The luminaire includes: a laser light source 2 for emitting laser light BL; a wavelength conversion member 3 including a laser light irradiation region E which is irradiated with the laser light BL, and adapted to be excited by the irradiation of the laser light BL to emit light subjected to wavelength conversion; a laser light scanning mechanism 4 for scanning the laser light BL with which the laser light irradiation region E is irradiated to form a light distribution pattern according to a scanning range S of the laser light BL; and a projection lens 200 for projecting illumination light forming the light distribution pattern in the forward direction. An incident angle of the laser light BL scanned by the laser light scanning mechanism 4 to the wavelength conversion member 3 is set as an angle which avoids the laser light BL from entering directly into the projection lens 200 when the wavelength conversion member 3 is involved in breakage, defect, or falling trouble.SELECTED DRAWING: Figure 4

    【課題】波長変換部材に欠陥や破損が生じた場合でも、レーザー光が投影レンズを通して外部に直接出射されることを防止した照明装置を提供する。【解決手段】レーザー光BLを出射するレーザー光源2と、レーザー光BLが照射されるレーザー光照射領域Eを含み、レーザー光BLの照射により励起されて波長変換された光を発する波長変換部材3と、レーザー光照射領域Eに照射されるレーザー光BLを走査することによって、レーザー光BLの走査範囲Sに応じた配光パターンを形成するレーザー光走査機構4と、配光パターンを形成する照明光を前方に向けて投影する投影レンズ200とを備え、レーザー光走査機構4により走査されるレーザー光BLの波長変換部材3に対する入射角が、波長変換部材3が破損、欠損又は脱落したときに、投影レンズ200に対してレーザー光BLが直接入射しない角度に設定されている。【選択図】図4
