Claim 12:
13. An illumination system configured to provide an illumination beam, comprising a red light source module, a blue light source module, a green light source module, a light splitting element, a first light combining element and a light uniforming element, wherein:
the red light source module is configured to generate a red light;
the blue light source module comprises a first blue light emitting element and a second blue light emitting element, the first blue light emitting element is configured to emit a first blue light, and the second blue light emitting element is configured to emit a second blue light, wherein a peak wavelength of the second blue light is less than a peak wavelength of the first blue light, and the light splitting element is configured to allow one of the first blue light and the second blue light to pass through, to reflect the other of the first blue light and the second blue light, and to guide both the first blue light and the second blue light to the first light combining element;
the green light source module is configured to generate a green light; and
the first light combining element guides the red light, the first blue light, the second blue light, and the green light into the light uniforming element, enabling the illumination system to output the illumination beam.
