Abstract
A projector includes a casing, an optical engine, and a heat dissipating module. The casing includes a first sidewall, a front wall defining a hole, a second sidewall, and a rear wall connected in sequence. The optical engine includes a lens module substantially aligned with the hole defined by the front wall, a DMD, and an illuminator module. The illuminator module is arranged at a side of the lens module away from the second sidewall, and includes a housing having a side surface away from the lens module and at least one light source installed on the side surface. The heat dissipating module includes a first heat sink attached to the at least one light source, a blower, and an exhaust fan. The blower is for blowing air towards the first heat sink from an air inlet.
