To provide an illumination device capable of illuminating both of a region conforming to a light distribution standard of a headlight and a region outside the light distribution standard by using a coherent light beam and finely controlling light distribution in each region.SOLUTION: An illumination device includes: a coherent light source that emits a first coherent light beam and a second coherent light beam; an optical element that diffuses the first coherent light beam to illuminate a first illumination region and diffuses the second coherent light beam to illuminate a second illumination region; and a timing control part that individually controls incidence timing of the first coherent light beam and the second coherent light beam on the optical element or illumination timing of the first illumination region and the second illumination region.SELECTED DRAWING: Figure 1

    【課題】コヒーレント光を用いて前照灯の配光規格に適合する領域および配光規格外の領域の両方を照明することができるとともに各領域内の配光を細かく制御することができる照明装置を提供する。【解決手段】照明装置は、第1コヒーレント光および第2コヒーレント光を発光するコヒーレント光源と、第1コヒーレント光を拡散させて第1被照明領域を照明し、かつ第2コヒーレント光を拡散させて第2被照明領域を照明する光学素子と、第1コヒーレント光および第2コヒーレント光の光学素子への入射タイミング、または第1被照明領域および第2被照明領域の照明タイミングを個別に制御するタイミング制御部と、を備える。【選択図】図1
