Abstract
An illumination system configured to provide an illumination beam is provided. At a timing for blue light, first blue light penetrates a light homogenizing element, so that the illumination system outputs blue light of the illumination beam. At a timing for green light, the first blue light is converted into first green light via a phosphor wheel and penetrates the light homogenizing element. At the same time, second blue light is converted into second green light via the phosphor wheel and penetrates the light homogenizing element, so that the illumination system outputs green light of the illumination beam. A projection device is also provided. According to the illumination system and the projection device provided herein, each light source may be effectively utilized.
