To provide a lighting device for a cabin which can selectively perform lighting by using illumination light which is high in a light concentration, and lighting by using illumination light for lighting the cabin in a wide range, and is easy in the adjustment of a color of the illumination light when lighting the cabin in the wide range.SOLUTION: A lighting device 1 comprises a light guide plate 4 which is arranged in a cabin, and includes a wavelength selection absorption material. The lighting device also comprises a mode selection part for selecting a map lamp mode and a room lamp mode by changing an orientation of a light source 10 with respect to the light guide plate 4. In the map lamp mode, light from the light source 10 is emitted to the outside not via the light guide plate 4, and in the room lamp mode, the light from the light source 10 is irradiated with toward the light guide plate 4, at least a part of the light is guided to the light guide plate 4, and after that, the light is emitted to the outside.SELECTED DRAWING: Figure 1

    【課題】集光性が高い照明光での照射と、車室を広範囲に照らす照射光での照射とを選択的に実現でき、照明光が車室を広範囲に照らす場合、照明光の色を調整し易い車室内用照明装置を提供すること。【解決手段】照明装置1が、車室内に設置され、波長選択吸収材料を含んだ導光板4を備える。導光板4に対する光源10の向きを変えることで、マップランプモードとルームランプモードを選択するためのモード選択部を備える。マップランプモードは、光源10からの光を導光板4を介さずに外部に出射し、ルームランプモードは、光源10からの光を導光板4に向けて照射してその光のうちの少なくとも一部を導光板4を導光させた後で外部に出射する。【選択図】図1
