ABSTRACT:
An image projection apparatus includes a lamp, an optical modulator which modulates light emitted from the lamp to correspond to image data, a ballast which operates the lamp, a power supply unit, and a duct in which the power supply unit, the ballast, and the lamp are accommodated. The duct includes a first absorption hole and a main exhaust hole that communicate with an outside, and forms an air-flow path on which the first absorption hole, the power supply unit, the ballast, the lamp, and the main exhaust hole are disposed.
