1. A light source system comprising:
a first light emitting diode (LED) light source emitting a first light beam;
a first concentrator comprising a first pair of Fresnel lenses with corrugated surfaces and concentrating the first light beam, the corrugated surfaces of the Fresnel lenses facing each other;
a second LED light source emitting a second light beam having a wavelength different from that of the first light beam;
a second concentrator comprising a second pair of Fresnel lenses with corrugated surfaces and concentrating the second light beam, the corrugated surfaces of the Fresnel lenses facing each other;
a beam splitter splitting the first concentrated light beam from the first concentrator and the second concentrated light beam from the second concentrator; and
a light guide guiding the split light beams, wherein
one end of the light guide is disposed substantially at a focal point of the first concentrated light beam and the second concentrated light beam that are reflected at and/or transmitted through the beam splitter so as to be collimated.
