Abstract
An illumination system includes a first light source, a first rotation wheel, a first phosphor element, and a light combining element. The first light source is capable of emitting a first color beam. The first rotation wheel is disposed on a transmission path of the first color beam and includes a first transmissive region and a first reflective region. The first transmissive region is capable of allowing the first color beam to pass through so as to form a first color transmissive beam. The first reflective region is capable of reflecting the first color beam to form a first color reflective beam. One of the first color transmissive and reflective beams excites the first phosphor element to form a second color beam. The light combining element combines the second color beam and a beam originating from the other one of the first color transmissive and reflective beams.
