Abstract

A light source device includes a light source, a wavelength conversion member, and a retroreflective optical member. The light source emits excitation light. The wavelength conversion member includes a first region irradiated with the excitation light and radiates, from the first region, converted light having a wavelength different from that of the excitation light. The retroreflective optical member reflects the converted light toward the first region. The first region is a region that is a part of the wavelength conversion member.
