Abstract

A projector includes a first light source, a second light source, a collimating lens, a wavelength conversion module and a dichroic mirror. The first light source and the second light source respectively emit a first illumination beam and a second illumination beam. The collimating lens includes a first part and a second part and configured to receive and transmit the first illumination beam. The wavelength conversion module receives the first illumination beam from the first part, and generates an excitation beam transmitted toward the first part and the second part. The dichroic mirror corresponds to the first part, and configured to reflect the first illumination beam and the second illumination beam respectively to different directions for projecting the first illumination beam onto the first part and to be passed by the excitation beam.
