To provide a lighting device which can attract an attention to an observation object, a moving body and a bundling system.SOLUTION: In a moving body 20 having a moving body main body 21 and a lighting device 30, the lighting device 30 has a light source and an optical element for projecting a pattern P on a projection face PP by controlling an advance direction of light from the light source. The pattern P includes a first element pattern PE1 aligned in a first direction D1, and a second element pattern PE2 aligned in the first direction D1. A position in which the first element pattern PE1 on the projection face PP is projected is different from a position in which the second element pattern PE2 on the projection face PP is projected in a second direction D2 which is nonparallel with the first direction D1. A space frequency of the first element pattern PE1 on the projection face PP is lower than a space frequency of the second element pattern PE2 on the projection face PP.SELECTED DRAWING: Figure 3

    【課題】観察対象の注意を引くことができる照明装置、移動体、照明方法及び建物システムを提供する。【解決手段】移動体本体21及び照明装置30を有している移動体20において、照明装置30は、光源と、光源からの光の進行方向を制御して投影面PP上にパターンPを投影する光学素子と、を有する。パターンPは、第1方向D1に配列された第1要素パターンPE1と、第1方向D1に配列された第2要素パターンPE2と、を含む。投影面PP上における第1要素パターンPE1が投影される位置は、第1方向D1と非平行な第2方向D2において、投影面PP上における第2要素パターンPE2が投影される位置と異なる。投影面PP上における第1要素パターンPE1の空間周波数は、投影面PP上における第2要素パターンPE2の空間周波数よりも小さい。【選択図】図3
