Abstract
An illumination system providing an illumination beam includes a light source module generating first to third color beams, a light splitting and combining element, a beam expanding and collimating module, a reflecting element, and a light combining module. The first and second color beams are reflected by the light splitting and combining element after being transmitted to the light splitting and combining element. Paths of the first and second color beams leaving the light splitting and combining element are coincident. The first and second color beams from the light splitting and combining element are expanded and collimated by the beam expanding and collimating module and transmitted to the light combining module. The third color beam is reflected by the reflecting element and transmitted to the light combining module. Paths of the first to third color beams after leaving the light combining module are coincident. A projection device is provided.
