Abstract
An illumination system adapted to provide an illumination light beam is provided. At a first timing, after an excitation light beam is reflected by a non-conversion reflecting region of a wavelength conversion wheel, the excitation light beam passes through a light splitting element, and is then reflected by a reflecting element, passes through the light splitting element a first lens group and a light uniformizing element in sequence, so as to output a first color light. At a second timing, a converted light beam is converted and reflected by a wavelength conversion reflecting region. A central axis of the excitation light beam reflected by the reflecting element and passing through the light splitting element and a central axis of the converted light beam reflected by the light splitting element are coincided with an optical axis of the first lens group. A projection device is also provided.
