Video projector

A video projector comprising:

• an optical component which transmits light to display an image;
• a cooling fan which generates a cooling current to cool the optical component;
• and
• a duct through which the cooling current circulates, with the duct including a first discharge port, and the first discharge port including:
• first and second wall surfaces opposed to each other in an optical axis direction in which the light is transmitted through the optical component;
• third and fourth wall surfaces opposed to each other in a lateral direction which is perpendicular to the optical axis direction;
• a discharge port inlet into which the cooling current from the cooling fan is drawn;
• and
• a discharge port outlet from which the cooling current is sent toward the optical component;
• wherein the first and second wall surfaces are spaced apart by a gap and the third and fourth wall surfaces are spaced apart by a gap, with the gaps becoming narrower from the discharge port inlet to the discharge port outlet.
