Abstract
A wavelength conversion wheel module and an illumination system are provided. The wavelength conversion wheel module includes a wavelength conversion wheel and a first actuator. The wavelength conversion wheel includes a plurality of annular areas. Each of the annular areas includes at least one wavelength conversion area and at least one light passing area. The wavelength conversion area converts an original light beam incident on the wavelength conversion area into a converted light beam. The wavelength of the converted light beam is different from the wavelength of the original light beam. The annular areas are arranged along the radial direction of the wavelength conversion wheel, and different annular areas have different optical parameters. The optical parameters of the annular areas are related to the wavelength conversion area and the light passing area. The first actuator is connected to the wavelength conversion wheel, and drives the wavelength conversion wheel to rotate.
