1. An illumination system configured to provide an illumination beam, the illumination system comprising a red light source, a green light source, a blue light source, a first supplementary light source, a first X-shaped light-splitting assembly, a first light-splitting element, and a light-uniforming element, wherein
the red light source provides a red beam,
the green light source provides a green beam,
the blue light source provides a blue beam,
the first supplementary light source provides a first supplementary beam,
the first X-shaped light-splitting assembly is configured to reflect the first supplementary beam and the red beam to the first light-splitting element, and is configured to allow the blue beam to pass through to the first light-splitting element,
the first light-splitting element is configured to guide the red beam, the green beam, the blue beam, and the first supplementary beam to be transmitted to the light-uniforming element, and
the light-uniforming element is configured to provide the red beam, the green beam, the blue beam, and the first supplementary beam from the first light-splitting element to form the illumination beam,
wherein the first supplementary beam is a red supplementary beam or a blue supplementary beam, and the illumination system comprises at least five light-emitting elements.
