Claim 7:
8. The illumination system according to claim 1, wherein the wavelength converter is a wavelength conversion wheel and has a wavelength conversion region, the wavelength conversion region is provided with a first wavelength conversion layer and a second wavelength conversion layer, the first wavelength conversion layer and the second wavelength conversion layer are sequentially cut into the transmission paths of the excitation light beams coming from the multi-region dichroic device, the first wavelength conversion layer converts the excitation light beams into a first converted light beam when the first wavelength conversion layer is located on the transmission paths of the excitation light beams, the second wavelength conversion layer converts the excitation light beams into a second converted light beam when the second wavelength conversion layer is located on the transmission paths of the excitation light beams, and the at least one second dichroic region comprises a first color filter region corresponding to the first converted light beam and a second color filter region corresponding to the second converted light beam for respectively allowing a portion of the first converted light beam and a portion of the second converted light beam to penetrate through.
