Projector

摘要

A projector includes a light source apparatus, a light modulator that modulates a light flux outputted from the light source apparatus in accordance with image information, a projection lens that projects the light flux modulated by the light modulator, an exterior enclosure that accommodates the light source apparatus, the light modulator, and the projection lens, an exhaust fan (first exhaust fan) that exhausts air inside the exterior enclosure out thereof through an exhaust port (first light source exhaust port) provided in the exterior enclosure, and a functional device (wireless device) that provides a predetermined function and is heated to a temperature higher than the temperature of the exhaust air from the first exhaust fan. The wireless device is disposed in a position downstream of the first exhaust fan, and part of the exhaust air discharged from the first exhaust fan flows to the wireless device.

主权项

1. A projector comprising:
a light source apparatus; a light modulator that modulates a light flux outputted from the light source apparatus in accordance with image information; a projection lens that projects the light flux modulated by the light modulator; an exterior enclosure that accommodates the light source apparatus, the light modulator, and the projection lens; an exhaust fan that exhausts air inside the exterior enclosure out thereof through an exhaust port provided in the exterior enclosure; a functional device that provides a predetermined function; and an exhaust duct including
an exhaust-port-side duct through which exhaust air discharged from the exhaust fan flows to the exhaust port, anda functional-device-side duct through which the exhaust air discharged from the exhaust fan flows to the functional device; wherein
an entrance to the functional-device-side duct, through which the exhaust air enters the functional-device-side duct, is formed in the exhaust-port-side duct,the exterior enclosure has a second exhaust port through which the exhaust air having flowed through the functional-device-side duct and flowed along the functional device is exhausted out of the exterior enclosure,the exhaust air is exhausted out of the exhaust port in a first direction being substantially the same as a direction in which the light flux exits the projection lens, andthe exhaust air is exhausted out of the second exhaust port in a second direction being opposite to the direction in which the light flux exits the projection lens.
