ABSTRACT:
A light source unit includes: a light source part that supplies light; an optical element that changes an optical path of the light from the light source part; and a wavelength conversion element that converts a wavelength of the light from the optical element. The optical element is movable, and the optical path of the light entering the wavelength conversion element from the light source part is shifted by moving the optical element.
