Abstract: A lighting device according to the present technology includes: a light source unit that has a light emitting element; a spatial light phase modulator that generates a plurality of reproduced images at intervals on an image surface by performing spatial light phase modulation on incident light from the light source unit; and a projection unit that superimposes and projects the plurality of reproduced images on a projection surface via different projection lenses.
