Abstract: An illumination apparatus includes: a case having an opening portion; a light source disposed in the case and including a plurality of light-emitting elements; a light diffuser which is disposed in the opening portion, and diffuses and transmits light emitted from the plurality of light-emitting elements; and a controller that controls light emission from the light source. The controller: controls light emission from the plurality of light-emitting elements to project an image on the light diffuser, the image changing with time; and when changing the light emission from the plurality of light-emitting elements changing the image, controls the light emission from the light source to keep a change in at least one of (i) a light amount, (ii) a color temperature, and (iii) a spectral distribution of light emitted from the illumination apparatus within a predetermined range.

Abstract: An illumination apparatus that is to be disposed in a recess formed in a part of a building includes: a light-emitting module that includes a board and a plurality of light-emitting elements disposed on the board; a light diffuser that has translucency and covers the light-emitting module; and a specular reflector that is disposed between the light-emitting module and the light diffuser. The light-emitting module emits light toward the light diffuser, and the specular reflector reflects light from the light diffuser.

Abstract: An illumination apparatus that is to be disposed in a recess formed in a part of a building includes: a light-emitting module that includes a board and a plurality of light-emitting elements disposed on the board; a light diffuser that has translucency and covers the light-emitting module; and a light reflector that includes a wall having light-reflecting properties and surrounding the plurality of light-emitting elements. Among the plurality of light-emitting elements, every two adjacent light-emitting elements are disposed on the board at a first interval. Among the plurality of light-emitting elements, a light-emitting element closest to the wall is disposed on the board with a second interval to the wall, the second interval being larger than ¼ of the first interval and smaller than the first interval.

Abstract: An illumination device is provided. The illumination device includes a substrate including a light-emitter. An instrument main body includes a substrate arrangement surface, with the substrate being on the substrate arrangement surface. A cover is attached to the instrument main body, covers the substrate, and is transparent. An antenna is on the cover and configured to receive a signal from an outside of the illumination device. A driver is on the instrument main body and configured to supply power to the light-emitter. A controller is configured to control the power supplied from the driver to the light-emitter based on the signal received by the antenna. The cover includes a diffusion factor from 40% to 90%.

Abstract: An illumination system includes: a first luminaire that is of an internal lighting type and includes a light emitter that emits first illumination light having a color simulating a sky; and a second luminaire that is of a projection type and includes a projector that projects, on an object, second illumination light having a color simulating sunlight. The first luminaire and the second luminaire are disposed in a same space, and the first luminaire is disposed higher with respect to a floor than a projection area created on the object by the second illumination light.
