Abstract
An illumination system, a projection apparatus, and a projection method of the projection apparatus are provided. The illumination system includes an excitation light source, a light combination element, a light wavelength conversion module, and an actuator. The light combination element is disposed on a transmission path of an excitation beam emitted from the excitation light source. The light wavelength conversion module is disposed on a transmission path of the excitation beam transmitted from the light combination element and has a plurality of optical areas. The actuator is coupled to the light combination element to change a rotation angle of the light combination element, such that the excitation beam transmitted from the light combination element is transmitted to the plurality of optical areas of the light wavelength conversion module via different transmission paths.
