Abstract: An illumination apparatus of the disclosure includes 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. A first emitted light emitted from first optical waveguide enters the first light converter and a second emitted light emitted from the second optical waveguide enters the second light converter. First power applied to the first optical waveguide and second power applied to the second optical waveguide are independent.

Abstract: A lamp includes: first and second semiconductor light-emitting elements adapted to emit excitation light; a wavelength conversion element adapted to convert the excitation light into light having a peak wavelength different from that of the excitation light; and a concave mirror adapted to reflect the excitation light emitted from the semiconductor light-emitting elements to the wavelength conversion element and reflect the light from the wavelength conversion element toward an outside of the lamp. A distance y1 from an optical axis of the first semiconductor light-emitting element to an optical axis of the concave mirror satisfies (D+Dphos)/2≦y1≦4f, and a distance y2 from an optical axis of the second semiconductor light-emitting element to the optical axis of the concave mirror satisfies 4f
