Abstract
An illumination system is provided, which includes a first solid-state light source, a second solid-state light source, a third solid-state light source, a light combining element, a light homogenizing element, a first plate and a first band-stop filter. The first solid-state light source to the third solid-state light source respectively provide a first-wavelength light beam to a third-wavelength light beam. The first plate has a first surface opposite to an outputting surface of the light combining element and a first phosphor, while the first phosphor is excited by the third-wavelength light beam to produce a fourth-wavelength light beam. The first band-stop filter allows the first-wavelength light beam to the third-wavelength light beam to pass therethrough and reflects the fourth-wavelength light beam. With these arrangements, the illumination system can strengthen the light of a specific color and the volume of the illumination system can be reduced.
