This illumination apparatus is provided with a semiconductor light-emitting element and a light conversion element. The semiconductor light-emitting element has a first optical waveguide and a second optical waveguide. The light conversion element has a first light converter and a second light converter. First emitted light emitted from the first optical waveguide enters the first light converter, and second emitted light emitted from the second optical waveguide enters the second light converter. A first power applied on the first optical waveguide and a second power applied on the second optical waveguide are independent.
