Abstract
A lamp unit configuring a light source device capable of efficiently cooling a light source by a simple structure includes a light source and a plurality of air outlets for discharging the cooling air for cooling the light source. The plurality of air outlets include a first air outlet for discharging the cooling air in a first direction and a second air outlet for discharging the cooling air in a second direction. The cooling air discharged through the first air outlet is different in airflow rate from the cooling air discharged through the second air outlet, and the first direction is different from the second direction when viewed in the direction of the optical axis of the light source.
