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.
