    Abstract: The disclosure provides an illumination system and a projection device applying the illumination system. The illumination system includes a laser light source, a wavelength conversion module, and a spot region modulation module configured to shift a transmission path of a laser beam. When the wavelength conversion module rotates, the spot region modulation module moves, in a first period of time, the laser beam in a wavelength conversion region of the wavelength conversion module along a first shift path, so that the laser beam forms a first spot region in an irradiation region in the wavelength conversion region. The spot region modulation module causes, in a second period of time, the laser beam to form a second spot region in an irradiation region in a non-conversion region of the wavelength conversion module. A size of the first spot region is greater than a size of the second spot region.
