Abstract
A projector projecting an image onto a screen, comprises a lamp emitting light; an optical system having an optical synthesizer including a blue panel, a green panel and a red panel, and an optical component disposed along an optical path from the lamp to the optical synthesizer; a cooling fan generating cool air cooling the optical system; and a guiding duct guiding the cool air to be distributed into a first passage and a second passage. With this configuration, the present invention provides a projector in which a guiding duct is partitioned and therefore cool air is distributed according to whether the cool air is sent to a relatively high temperature place or a relatively low temperature place in an optical system, preventing energy from being wasted by efficiently cooling some components of the optical system without overcooling others, and reducing noise caused by a cooling fan and air flow.
