Abstract: With a simple configuration, a clear illumination area with suppressed blurring is formed, and a form such as position, shape, and size thereof is changed. Divergent light from a point light source is shaped by a collimating optical system and emitted to a hologram element. Since the point light source is arranged at a front focal position of the collimating optical system, the light emitted from the collimating optical system is emitted to the hologram element as parallel light, and diffracted light therefrom forms an illumination area at a predetermined position on an illumination target surface. A light scanning part rotating about a predetermined rotation axis is arranged between the point light source and the collimating optical system, and light incident on the collimating optical system is scanned. By this scanning, an incident angle of the parallel light incident on the hologram element changes, and the illumination area changes.
