Abstract
A lamphouse () is configured to accommodate and cool an image projector lamp (). The lamphouse receives through an air intake opening () cool airflow (A) drawn by a fan and is equipped with an internal chamber () and plural internal fins (). Plural exhaust openings () on the downstream side of the lamp reflector () and burner () are arranged essentially perpendicular to the direction of flow of air (A) heated by the lamp and such that, when the airflows from the surroundings (A) and (A) are mixed in the area immediately after the lamphouse, a resulting airflow (A) will, upon reaching projector exhaust openings (), have a substantially uniform and relatively low temperature. The exhaust openings () are configured so that the heated airflow is mixed with the cooler airflow before striking the projector chassis reaching the projector exit grill.
