Claim 1:
2. The projection device according to claim 1, wherein in a first time interval, the wavelength conversion region, the first region of the diffuser element, and the filter element cut into the transmission path of the laser beam, the wavelength conversion region emits a conversion beam after excited by the laser beam, and the conversion beam is transmitted to the first region and the filter element, wherein the conversion beam penetrating the first region serves as the first beam;
in a second time interval, the non-wavelength conversion region and the second region of the diffuser element cut into the transmission path of the laser beam, and the laser beam is sequentially transmitted to the non-wavelength conversion region and the second region, wherein the laser beam penetrating the second region serves as the second beam.
