Abstract

An illumination system includes an excitation light source module, a light splitting and combining module, a filter module, and a wavelength conversion module. The excitation light source module provides an excitation beam. The light splitting and combining module is disposed on a transmission path of the excitation beam. The excitation beam includes a first and a second excitation beam which are different from each other in polarization state or wavelength range. The filter module is disposed on the transmission path of the excitation beam. The filter module includes a light passing area configured to allow the excitation beam to pass there-through and a light filtering area. The wavelength conversion module is disposed on the transmission path of the excitation beam reflected by the light filtering area and configured to convert the reflected excitation beam into a conversion beam. A projection apparatus including the above illumination system is also provided.
