To provide a luminaire that is used for a headlight system of a vehicle etc., and can have a light projection direction selected, and that projects light in a selected projection direction under simple control.SOLUTION: A luminaire 12 has: an excitation light source 20; a spatial optical modulator 22 which functions as a computer-generated hologram to convert excitation light EL from the excitation light source 20 into an excitation light pattern ELP; a phosphor 24 which is excited with the excitation light pattern ELP from the spatial optical modulator 22 to emit a light pattern LP having a pattern shape corresponding to the excitation light pattern ELP; and a projection optical system 26 which projects the light pattern LP from the phosphor 24.SELECTED DRAWING: Figure 2

    【課題】車両のヘッドライトシステムなどに使用され、光の投射方向を選択可能な照明装置において、簡単な制御で選択された投射方向に光を投射する。【解決手段】照明装置12は、励起光源20と、励起光源20からの励起光ELを励起光パターンELPに変換する計算機生成ホログラムとして機能する空間光変調器22と、空間光変調器22からの励起光パターンELPによって励起し、励起光パターンELPに対応するパターン形状を備える光パターンLPを発光する蛍光体24と、蛍光体24からの光パターンLPを投射する投射光学系26とを有する。【選択図】図2
