Abstract
In an optical engine for a projection system, a fan unit is mounted on an upper surface of a housing, and has an inlet port facing toward light modulators within the housing for drawing air upwardly so as to dissipate heat generated by the light modulators, and an outlet port that is transverse to the inlet port for discharging the air drawn into the inlet port.
