Claim 13:
14. The light source system according to claim 12, further comprising:
a collecting lens group adjacent to the wavelength conversion element,
wherein the adjustment device is configured to adjust a divergence angle of a light beam of the red laser light and a divergence angle of a light beam of the green laser light, in such a manner that after exiting from the first light splitting and combining element and being condensed by the collecting lens group, the second blue laser light, the red laser light, and the green laser light are incident onto the wavelength conversion element to form coincident light spots; and wherein the excited light which is yellow, the red laser light, and the green laser light are emitted from the wavelength conversion element, collimated by the collecting lens group and then incident to the edge region.
