Abstract

The invention provides an illumination system, configured to provide an illumination beam. The illumination system includes blue, green, and red laser modules respectively configured to provide blue, green, and red beams and a wavelength conversion component. The wavelength conversion component includes a wavelength conversion region and an optical output region. In a first time interval, the blue, green, and red beams are sequentially transmitted to the optical output region, where the illumination beam includes the blue, green, and red beams. In a second time interval, the blue beam is transmitted to the wavelength conversion region to form a converted beam, where the illumination beam includes the converted beam. A projection device including the illumination system is also provided. The projection device using the illumination system in the invention achieves color performance of a wide color gamut at relatively low costs.
