Projector

A projector comprising:

• a lens;
• a beam processing module disposed relative to the lens;
• a plurality of digital micromirror devices disposed around the beam processing module, a beam projecting path being defined between the lens and at least one digital micromirror device;
• a reflecting module disposed relative to the plurality of digital micromirror devices and located beyond the beam projecting path;
• and
• an illumination module disposed relative to the reflecting module;
• wherein an initial beam projected by the illumination module is reflected to the plurality of digital micromirror devices by the reflecting module, so that the plurality of digital micromirror devices generates a plurality of image beams, and the beam processing module combines the plurality of image beams to form a projecting beam and projects the projecting beam onto the lens along the beam projecting path;
• wherein a beam emitting path is defined between the reflecting module and the digital micromirror device, an angle between the beam projecting path and the beam emitting path is greater than or equal to twenty degrees.
