Abstract
A light source device includes: a first light emitting unit including a light emitting element that emits light having a predetermined wavelength range; a second light emitting unit including a wavelength conversion member that receives the light from the light emitting element and emits light having a different wavelength range different than the predetermined wavelength range; an optical unit configured to define a path of the light emitted from the light emitting element and a path of the light emitted from the wavelength conversion member; an air blowing unit configured to generate a cooling air; and a passage forming member configured to form a passage through which the cooling air flows, the passage being in contact with both of the first light emitting unit and the second light emitting unit.
