Abstract
A phosphor wheel unit includes a phosphor wheel that converts incident light into fluorescent light and emits the fluorescent light, a first heat exchanger having a plurality of fin members that is arranged and an airflow inlet surface through which an airflow generated by rotation of the phosphor wheel partially or entirely flows in, and a regulating member that regulates a direction of the airflow. The direction of the airflow regulated by the regulating member and a direction perpendicular to a rotation shaft of the phosphor wheel form an angle of between 0 degrees and 45 degrees on a surface perpendicular to an extending direction of a base material of the phosphor wheel. The airflow inlet surface is disposed intercepting the direction of the airflow regulated by the regulating member. The first heat exchanger cools a gas forming the airflow and the cooled gas returns to the phosphor wheel.
