Claim 0:
1. An illumination system, configured to provide an illumination light and comprising a first laser light source, a second laser light source, a wavelength conversion module, a first light splitting element, and a microlens array, wherein
the first laser light source is configured to provide a first laser light in a first time interval;
the second laser light source is configured to provide a second laser light in a second time interval, wherein the first laser light source is turned on in the first time interval and turned off in the second time interval, the second laser light source is turned off in the first time interval and turned on in the second time interval,
the wavelength conversion module is located on a transmission path of the first laser light, wherein the wavelength conversion module comprises at least one wavelength conversion region and at least one non-conversion region, and the wavelength conversion module is configured to rotate, such that the at least one wavelength conversion region and the at least one non-conversion region are alternately cut into the transmission path of the first laser light;
the first light splitting element is located on the transmission path of the first laser light and a transmission path of the second laser light, wherein when the first laser light is incident to the at least one non-conversion region of the wavelength conversion module, the first laser light forms a first color light by the first light splitting element and the at least one non-conversion region of the wavelength conversion module, and when the first laser light is incident to the at least one wavelength conversion region of the wavelength conversion module, the first laser light forms at least one second color light by the first light splitting element and the wavelength conversion module, the second laser light forms a third color light after passing through the first light splitting element in the second time interval; and
the microlens array is located on transmission paths of the first color light, the at least one second color light and the third color light, and the microlens array is configured to homogenize the first color light, the at least one second color light and the third color light, wherein the first color light, the at least one second color light and the third color light form the illumination light in different time intervals after passing through the microlens array,
wherein peak wavelength ranges of the first color light, the at least one second color light, and the third color light do not overlap each other.
