PROBLEM TO BE SOLVED: To solve the problem that a space in a vehicle sometimes feels like a narrow space.SOLUTION: A first light source unit 21, a second light source unit 22, and a third light source unit 23 are arranged sequentially in the width direction on the right side at the center of the width direction of a vehicle. A first light source reflection plate 31 is arranged between the first light source unit 21 and the second light source unit 22. A second light source reflection plate 32 is arranged between the second light source unit 22 and the third light source unit 23. The first light source reflection plate 31 and the second light source reflection plate 32 are inclined so as to be closer to a floor as they are farther from the center of the width direction. The intervals among the first light source unit 21, the second light source unit 22, and the third light source unit 23 are wider as they are farther from the center of the width direction. The length wof the first light source reflection plate 31 and the length wof the second light source reflection plate 32 between the adjacent light source units are longer as they are farther from the center of the width direction.SELECTED DRAWING: Figure 2

    【課題】車両内の空間が狭い空間のように感じられることがある。【解決手段】車両の幅方向中央の右側に、第1光源ユニット21、第2光源ユニット22及び第3光源ユニット23が幅方向に順に配置されている。第1光源ユニット21と第2光源ユニット22との間には、第1光源反射板31が配置されている。第2光源ユニット22と第3光源ユニット23との間には、第2光源反射板32が配置されている。第1光源反射板31と第2光源反射板32は幅方向中央から遠ざかるほど床に近付くように傾斜している。第1光源ユニット21と第2光源ユニット22と第3光源ユニット23の間隔は幅方向中央から遠ざかるほど広い。隣り合う光源ユニット間における第1光源反射板31の長さw1及び第2光源反射板32の長さw2は幅方向中央から遠ざかるほど長い。【選択図】図2
