Claim 0:
1. A light source apparatus comprising:
an excitation light emitter configured to irradiate excitation light;
a phosphor configured to receive the excitation light and to convert the excitation light into wavelength band light different from the excitation light; and
a color wheel device,
wherein a first region of regions divided in a radial direction of the color wheel device comprises a first transparent part configured to transmit the wavelength band light, the radial direction being a direction outward from a center of the color wheel device,
wherein a second region, which is different from the first region of the regions divided in the radial direction of the color wheel device, comprises a reflector configured to reflect the excitation light and to change a light path and a second transparent part configured to transmit the excitation light, and
wherein the phosphor is arranged on a light path of the excitation light reflected by the reflector or on a light path of the excitation light transmitted by the second transparent part.
