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.
