LIGHT SOURCE DEVICE AND PROJECTION-TYPE DISPLAY DEVICE

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.
