Claim 3:
4. The projection system of claim 2, wherein the light source apparatus comprises:
a light source module comprising a first light source sub-module and a second light source sub-module, configured to respectively emit a first beam of the first primary colour light and a second beam of the first primary colour light; and
a first fluorescence plate and a second fluorescence plate, optically aligned with, and configured to receive, the first beam of the first primary colour light and the second beam of the first primary colour light respectively;
wherein:
the first fluorescence plate comprises a transmission zone and a first fluorescence zone on a surface thereof facing the first beam of the first primary colour light, wherein the first fluorescence zone comprises a first fluorescence material capable of generating the second primary colour light upon excitation by the first primary colour light, wherein the first fluorescence plate is further configured to have the transmission zone and the first fluorescence zone to alternately align with the first beam of the first primary colour light in a predetermined manner such that the first beam of the first primary colour light transmitted through the transmission zone and a beam of the second primary colour light generated from the first fluorescence zone are coupled in a time-sharing manner to be outputted as the fifth light field; and
the second fluorescence plate comprises a second fluorescence zone comprising a second fluorescence material on a surface thereof facing the second beam of the first primary colour light, configured such that upon excitation by the second beam of the first primary colour light, a beam of the third primary colour light is generated from the second fluorescence zone to be outputted as the sixth light field.
