Abstract
A light source device includes: a light source to emit an excitation light beam having a first wavelength; a heat generation member to convert the first wavelength of the excitation light beam emitted from the light source into a light beam having a second wavelength different from the first wavelength; a substrate to which the heat generation member is attached; a motor to rotate the substrate; a bracket to hold the motor; a casing having an opening penetrating through the casing; and a cooling member connected to the bracket. The casing accommodates the light source, the heat generation member, the substrate, and the bracket. The cooling member cools the heat generation member via the bracket; and seals the opening.
