Abstract:
A light source includes a discharge lamp that outputs light, a discharge lamp driver that supplies drive power to the discharge lamp, a cooling unit that cools the discharge lamp, and a control unit that controls the cooling unit, and the control unit controls the cooling unit based on control information representing a relationship a rotation speed of the cooling unit between at least one of temperature information of the discharge lamp and a voltage between electrodes of the discharge lamp.
