Abstract

An optical engine module used in a projection device and configured to generate an image beam includes a housing and a plate. The housing has a surrounding side wall and a bottom wall connected to each other. The bottom wall has a first opening. The surrounding side wall has an off-state beam irradiation zone adjacent to the first opening. The first opening is configured to allow the image beam to exit. The off-state beam irradiation zone is configured to be irradiated by an off-state beam. The plate has a light receiving part and a heat dissipating part. The light receiving part is disposed in the off-state beam irradiation zone. The heat dissipating part passes through the bottom wall and extends out of the housing. A projection device adopting the optical engine module is also provided.
