Image projection apparatus

An image projection apparatus projecting an image using light from a light source, the image projection apparatus comprising:

• an exhaust air outlet through which an exhaust air flows out from an inside of the apparatus to an outside thereof;
• an air inlet through which an external air flows in from the outside of the apparatus to the inside thereof;
• a temperature detector that detects a temperature of the external air flowing into the inside of the apparatus through the air inlet;
• and
• a controller that performs a protection operation when one of a predetermined temperature corresponding to a temperature of the exhaust air, a temperature being higher than the predetermined temperature, a predetermined temperature change caused by flowing in of the exhaust air through the air inlet, or a temperature change being larger than the predetermined temperature change, is detected by the temperature detector,
• wherein the air inlet is adjacent to the exhaust air outlet.
