ILLUMINATION DEVICE AND VEHICLE

摘要

[Problem] To provide an illumination device with which it is possible to use coherent light to illuminate both a region conforming to the light-distribution specifications of headlights and regions non-compliant with said distribution specifications, and with which it is possible to finely control the light distribution within these regions. [Solution] An illumination device is provided with: a coherent light source for emitting first coherent light and second coherent light; an optical element for diffusing the first coherent light and illuminating a first region for illumination, and wave-diffusing the second coherent light and illuminating a second region for illumination; and a timing control unit for independently controlling the timing at which the first coherent light and the second coherent light are incident upon the optical element, and the illumination timing of the first region for illumination and the second region for illumination.
