Abstract
A light source includes a light source unit which supplies first wavelength light, a wavelength converting unit which converts the first wavelength light into second wavelength light different from the first wavelength light, and a leakage preventing unit which prevents leakage of the first wavelength light out of the light source. The area where the light source unit and the wavelength converting unit are disposed is optically separated from the area where the leakage preventing unit is disposed.
