摘要： Provided is an image projection apparatus, such as a projector, including a light source; an image generating element such as a DMD that receives light from the light source and forms an image; an image generating unit that irradiates the image generating element with the light from the light source; a first optical system including multiple transmission refractive optical elements; a second optical system arranged on an optical path of outgoing light of the first optical system and including a reflection optical element; and a projection optical system that enlarges and projects an image conjugate to the image generated by the image generating element as a projected image. The light source, the image generating unit, and the first optical system are arranged side by side in series in a direction parallel with the projected image plane.

摘要： An image projection apparatus includes a light source; an intake port to take in low-temperature air into the image projection apparatus; an exhaust port to exhaust air from the image projection apparatus; a ventilation unit to generate an air flow from the intake port to the exhaust port; a first flow path for hot-air exhaust having increased its temperature by taking heat from the light source; a second flow path for a part of the low-temperature air, taken from the intake port; and a mixing unit to mix the hot-air exhaust flowing from the first flow path and the low-temperature air flowing from the second flow path. The air mixed and exhausted from the mixing unit converges with another part of the low-temperature air, flowing from a third flow path set outside the mixing unit, at a space between the mixing unit and the exhaust port.
