Classification: CPC G  H | IPC G  H

Claim 0:
1. A light source apparatus comprising:
a first light source that emits first light that belongs to a first wavelength band;
a second light source that emits second light that belongs to a second wavelength band;
a wavelength converter that contains a phosphor and converts the first light emitted from the first light source into third light that belongs to a third wavelength band different from the first wavelength band;
a first heat dissipation member that includes a first base and a plurality of first fins and dissipates heat generated by the first light source, the plurality of first fins extending from the first base in a first extending direction; and
a second heat dissipation member that includes a second base and a plurality of second fins and dissipates heat generated by the second light source, the plurality of second fins extending from the second base in a second extending direction perpendicular to the first extending direction,
wherein a first direction in which first channels, which are specified by gaps between the plurality of first fins and along which a refrigerant is supplied, extend coincides with a second direction in which second channels, which are specified by gaps between the plurality of second fins and along which the refrigerant is supplied, extend, the first direction and the second direction being perpendicular to the first extending direction and the second extending direction.
