摘要： A light source device is equipped with a light source main unit, an optical element, a phosphor unit, and a condensing element. The optical axis of the light source main unit is shifted from the optical axis of the condensing element. The reflection direction of light of a first wavelength in a reflecting region intersects direction of the light of the first wavelength incident to the reflecting region. In response to the irradiation of the light of a first wavelength, fluorescent regions emit light of a second wavelength in a direction opposite to the direction of light of the first wavelength incident to the reflecting region and in the direction of reflection of light of the first wavelength in the reflecting region. In addition, fluorescent regions are capable of reflecting light of the second wavelength that is incident to the fluorescent regions. The direction of reflection of light of the second wavelength in the optical element is the same as the direction of light of the first wavelength that has passed through the optical element.

摘要： The purpose of the present invention is to provide a device that is small in size and low noise, in which heat from a light emitting element such as an LD or an LED is efficiently dissipated. A light source device includes a first light emitting element, a base plate, and an air flow device for sending out air. The base plate, which is thermally connected to the first light emitting element, has a flat surface formed around the first light emitting element to face the emitting direction of light output from the first light emitting element. The air flow device generates a flow of air toward the flat surface of the base plate in a direction perpendicular to the flat surface.
