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.

Abstract: A light environment rendering system includes: one lighting apparatus disposed on a part of a structure to form an illumination space; another lighting apparatus disposed on the part of a structure, at a position different from a position at which the one lighting apparatus is located, to form the illumination space; and a system controller which controls an operation of each of the lighting apparatuses. The system controller determines an illumination mode based on sky information that indicates at least one of a brightness and a color tone of a sky which are determined at least based on an azimuth direction and a height of the sun, and causes each of the lighting apparatuses to perform lighting simulating a sky according to the illumination mode.

Abstract: An illumination apparatus includes: a case having an opening portion; a first light source disposed in the case and including a plurality of light-emitting elements; a light diffuser which is disposed in the opening portion, diffuses and transmits light emitted from the first light source, and from which the diffused light and the transmitted light exit; a light emission component disposed outside a light exit region of the light diffuser on a light exit surface side of the light diffuser; and a second light source that emits light to the light emission component to cause the light emission component to radiate light.

Abstract: A lighting apparatus includes: a light source; a reflector plate which reflects light; and a diffuser plate which is light transmissive and is disposed to face the reflector plate. A gap between the diffuser plate and the reflector plate gradually decreases from a lower portion side of the diffuser plate and the reflector plate to an upper potion side of the diffuser plate and the reflector plate. The light source is disposed on the lower portion side to emit light toward the diffuser plate and the reflector plate.
