Abstract

A lighting apparatus includes: a case having an opening portion; a light emission panel in the case, the light emission panel having a light emission surface which emits light having a light distribution which dynamically changes; and a light distribution modification panel in the opening portion and having a distribution-modified light emission surface which modifies the light distribution of the light to emit light having a modified light distribution. The light emission panel emits, as the light having the light distribution, light having at least one of a luminance distribution and a chromaticity distribution of a first image to be presented on the light emission surface. The light distribution modification panel diffuses and transmits the light emitted from the light emission surface to emit light such that the at least one distribution of a second image to be presented on the distribution-modified light emission surface is changed to a blurred state.
