Abstract: A three-dimensional image lighting apparatus includes one or more light guides configured to guide paths of lights incident from one or more light sources toward a light distribution space, and to emit the lights, one or more divergence lenses disposed on the light distribution space so as to extend along the light guides, and configured to diverge the lights, which are incident from the light guides, in a linear shape, a half mirror disposed on one side of the divergence lenses, and a mirror disposed on the other side of the divergence lenses so as to face the divergence lenses, and configured to reflect the lights, which are diverged by the divergence lenses, between the half mirror and the mirror.
