Abstract
Disclosed is a light source device including a light source that includes a light emitting tube; and a cooler configured to cool the light emitting tube. The cooler includes an inlet port for drawing cooling air for cooling the light emitting tube; a flow channel that extends from the inlet port to the light emitting tube in a horizontal direction and that is for flowing the cooling air toward the light emitting tube; and a baffle plate that is disposed in the flow channel and that can slide in a gravity direction. The baffle plate has a shape and openings such that, in an installation state, an upper portion of the flow channel is opened and a lower portion of the flow channel is closed by the shape and positions of the openings of the baffle plate.
