Image projection apparatus

An image projector, comprising:

• a user interface to input information from a user;
• a light source to emit light, the light source being disposed below at least part of the user interface and in vertical alignment with the user interface, when the image projector is in an orientation in which the image projector projects onto a vertical surface;
• a flow path in which air flow towards an exhaust port of the image projector flows, at least a portion of the flow path being disposed directly between the light source and the user interface
• an intake port to pass air to an interior of the image projector, the intake port being disposed on a surface different from a horizontal surface of the image projector, when the image projector is in the orientation in which the image projector projects onto the vertical surface,
• wherein the flow path is disposed between the light source and the user interface so that at least part of the intake port and at least part of the exhaust port are connected with each other,
• the image projector further comprising:
• an image generator to generate an image using the light source;
• and
• a concave mirror to reflect the image from the image generator toward a projection plane,
• wherein the intake port, the exhaust port, and the concave mirror are disposed on a straight line, and
• the air flowing from the intake port toward the exhaust port flows along a rear surface of the concave mirror.

• image projector further comprising:
• an image generator to generate an image using the light source;
• and
• a concave mirror to reflect the image from the image generator toward a projection plane,
• wherein the intake port, the concave mirror, and the exhaust port are arranged in this order in a direction from the intake port to the exhaust port, and
• the air flowing from the intake port toward the exhaust port flows along a rear surface of the concave mirror.

An image projector, comprising:

• a user interface to input information from a user;
• a light source to emit light, the light source being disposed below at least part of the user interface and in vertical alignment with the user interface, when the image projector is in an orientation in which the image projector projects onto a vertical surface;
• and
• an exhaust port having a level between the light source and the user interface;
• a fan to flow air between the light source and the user interface, the air flowing between the light source and the user interface having a lower temperature than air flowing from the light source toward the exhaust port, when the light source is illuminated;
• an image generator to generate an image using the light source;
• and
• a concave mirror to reflect the image from the image generator toward a projection plane,
• wherein the air having the lower temperature flows over a rear surface of the concave mirror.
