Abstract
An illumination system and a projection apparatus including the illumination system are provided with a rotatable light splitting module, wherein when a light splitting element rotates, a first laser beam forms a first color light through a reflecting region of the light splitting element and a light combining element during a first time period, a second laser beam passes through the light combining element to form a second color light during the second time period and the fourth time period, the first laser beam forms a third color light by the wavelength conversion module and the light combining element after passing through the transmitting region of the light splitting element during the third time period, and the first color light, the second color light and the third color light from the light combining element form an illumination beam.
