Claim 14:
15. The projection system of claim 14, wherein the light source apparatus comprises:
a light source module comprising a third light source sub-module and a fourth light source sub-module, configured to respectively emit a first beam of the third primary colour light and a second beam of the third primary colour light; and
a third fluorescence plate, optically aligned with, and configured to receive, the first beam of the third primary colour light;
wherein:
the third fluorescence plate comprises a third fluorescence zone and a fourth fluorescence zone on a surface thereof facing the first beam of the third primary colour light, wherein:
the third fluorescence zone comprises a third fluorescence material capable of generating the first primary colour light upon excitation by the third primary colour light;
the fourth fluorescence zone comprises a fourth fluorescence material capable of generating the second primary colour light upon excitation by the third primary colour light; and
the third fluorescence plate is further configured to have the third fluorescence zone and the fourth fluorescence zone to alternately face the first beam of the third primary colour light in a predetermined manner such that a beam of the first primary colour light generated from the third fluorescence zone and a beam of the second primary colour light generated from the fourth fluorescence zone are coupled in a time-sharing manner to be outputted as the fifth light field;

and
the second beam of the third primary colour light is outputted as the sixth light field.
