ABSTRACT:
A projector includes a light source unit that emits light, a lamp driving unit that supplies a driving power to the light source unit, a power supply unit that supplies a power to at least the lamp driving unit, a fan that circulates cooling air to the lamp driving unit and the power supply unit, a distribution unit that distributes air volumes of the cooling air by the fan to the lamp driving unit and the power supply unit, and changes the air volumes of the cooling air distributed to the lamp driving unit and the power supply unit, and a distribution control unit that performs driving control on the distribution unit so as to change the air volumes of the cooling air distributed to the lamp driving unit and the power supply unit in accordance with the driving power supplied to the light source unit.
