Abstract
An image projection apparatus is disclosed which is capable of reducing noise when airflows from plural flow paths are taken in into a fan and exhausted therefrom. The apparatus comprises a first flow path through which a first airflow for cooling a light source passes, a second flow path through which a second airflow for cooling constituent parts other than the light source passes, a fan which exhausts air introduced from the first and second flow paths to the outside of the apparatus, a third flow path which introduces a third airflow to an exhaust area between the light source and the fan in the first flow path, and a light-shielding member which is provided in the exhaust area and shields the light from the light source.
Claims6
An image projection apparatus which projects an image using light from a light source, comprising:
- a first flow path through which a first airflow for cooling the light source passes;
- a second flow path through which a second airflow for cooling constituent parts other than the light source passes;
- a fan which exhausts air introduced from the first and second flow paths to the outside of the apparatus;
- a third flow path which introduces a third airflow to an exhaust area between the light source and the fan in the first flow path;
- and
- a light-shielding member which is provided in the exhaust area and shields the light from the light source.
