To provide an illuminating device having good visibility.SOLUTION: An illuminating device comprises: a first light source 11 for emitting coherent light; a second light source 12 for emitting incoherent light; a display unit 13 comprising a light guide body 31 for guiding the coherent light emitted from the first light source 11 and the incoherent light emitted from the second light source 12, and a display plate 35 for generating a speckle pattern from the coherent light, and for radiating the coherent light and the incoherent light; and a control unit for controlling driving of the first light source 11 and driving of the second light source 12.SELECTED DRAWING: Figure 4 【課題】視認性のよい照明装置を提供する。【解決手段】コヒーレント光を出射する第１光源１１と、インコヒーレント光を出射する第２光源１２と、第１光源１１から出射されるコヒーレント光および第２光源１２から出射されるインコヒーレント光を導光する導光体３１と、前記コヒーレント光からスペックルパターンを発生させる表示板３５を備えて前記コヒーレント光および前記インコヒーレント光を放射する表示ユニット１３と、第１光源１１の駆動と第２光源１２の駆動を制御する制御部と、を有する。【選択図】図４
