Abstract:
A light-projecting device according to the present invention includes a plurality of light source units including (i) a light emitting section that emits light upon receiving a laser beam and (ii) a reflector. Each of the light source units project light to a corresponding one of light-projected spots which is a region to which light is projected in an illuminated region in a partitioning manner, and the illuminated region is formed by combining a plurality of the light-projected spot.
