Abstract:
An illumination apparatus includes a first wavelength converter which absorbs part of the first excitation light and emits first wavelength-converted light, a second wavelength converter which absorbs part of the first excitation light and emits second wavelength-converted light, a reflector including a reflecting surface which is arranged to surround the members, and a holder which holds the members. A first region where light distribution angles of light emitted from the members have a predetermined value or less and a second region where the light distribution angle is less than the predetermined value are present in a region surrounded by the reflecting surface. The holder holds at least one part of the wavelength converter and at least one part of the second wavelength converter at the first region.
