Abstract:
1. A projector comprising: a plurality of light modulation devices, each modulating light in accordance with image information; a first fan discharging a first cooling air; a second fan discharging a second cooling air; a first duct connected at one end with the first fan, the first cooling air flowing through the first duct from the first fan; and a second duct connected at one end with the second fan, the second cooling air flowing through the second duct from the second fan, wherein the first cooling air flowing through the first duct and the second cooling air flowing through the second duct collide at a position where the first duct and the second duct communicate with each other at an other end of the first duct and an other end of the second duct, and a light modulation device of the plurality of light modulation devices is cooled by the first cooling air and the second cooling air, a flow direction of the first cooling air and a flow direction of the second cooling air being changed by collision of the first cooling air and the second cooling air.
