Abstract
A light source apparatus includes a first light emitter, a second light emitter, and a third light emitter. The first light emitter has a peak wavelength within the range from 600 nm to 660 nm and a wavelength range at half peak intensity wider than the range from 600 nm to 660 nm, the second light emitter has a peak wavelength within the range from 530 nm to 570 nm and a wavelength range at half peak intensity wider than the range from 530 nm to 570 nm, and the third light emitter which a peak wavelength is 420 nm-470 nm in a spectral power distribution thereof.
