Projector device

A projector device, comprising:

• an illumination module including:
• a light source generator configured to generate a colored light beam;
• and
• an optical processor configured to receive the colored light beam and convert the colored light beam into an image light beam;
• and
• an imaging module connected to the illumination module, and being configured to receive the image light beam and project the image light beam onto an imaging surface;
• wherein the imaging module includes:
• a housing having a first annular receiving groove and a second annular receiving groove;
• wherein the first annular receiving groove and the second annular receiving groove are spaced apart from each other, the first annular receiving groove is closer to the illumination module than the second annular receiving groove, and a center axis line of the first annular receiving groove and a center axis line of the second annular receiving groove are located on the same axis line;
• a relay optical system including at least one lens;
• wherein the lens of the relay optical system is received in the first annular receiving groove;
• and
• a projection optical system including at least one lens and a reflecting mirror;
• wherein the lens and the reflecting mirror of the projection optical system are received in the second annular receiving groove, and the lens of the projection optical system is located between the reflecting mirror and the relay optical system;
• wherein a mirror center of the lens of the relay optical system, a mirror center of the lens of the projection optical system, and a mirror center of the reflecting mirror are located on the same axis line.
