Light source device and projector

Abstract

A light source device includes a light source for emitting light, a heat dissipation member for dissipating heat of the light source, a wavelength conversion device for converting a wavelength of the light emitted from the light source, a housing chassis having a housing space in which the light source and the wavelength conversion device are housed, and a heat transfer member that is provided to the housing chassis to constitute a part of an outer surface of the housing chassis, and is thermally coupled to the wavelength conversion device, wherein the heat dissipation member includes a substrate to which the heat of the light source is transferred, and a plurality of fins arranged at the substrate, and the substrate has a circulation port that penetrates the substrate to allow a part of an air current flowing through the heat dissipation member to flow through the heat transfer member.
