The projection device includes the light source module, an optical engine module, a heat dissipation module, and a projection lens. The light source module includes a light emitting unit, a carrier, and a noise reduction unit. The light emitting unit is configured for providing a lighting beam. The carrier is configured for fixing the light emitting unit and has an opening, and the light source of the light emitting unit is aligned with the opening. The noise reduction unit is configured to surround at least a part of the light emitting unit. The optical engine module includes a light valve located on a transmission path of the lighting beam and is configured for converting the lighting beam into an image beam. The light source module is located between the optical engine module and the heat dissipation module.
