Abstract
A light source unit according to an aspect of the present disclosure includes: a phosphor; a condenser lens; a first light source part; and a second light source part. The phosphor emits fluorescent light based on first excitation light and second excitation light. The condenser lens condenses the first excitation light and the second excitation light on the phosphor. The first light source part emits the first excitation light such that the first excitation light forms a first light intensity distribution on the phosphor. The second light source part emits the second excitation light such that the second excitation light forms a second light intensity distribution different from the first light intensity distribution, on the phosphor.
