Abstract: A light source system and a projection system. The light source system comprises: an excitation light source (101) for emitting excitation light in at least a first time sequence and a second time sequence; a compensation light source (102) for emitting compensation light in at least a third time sequence, the compensation light emitted by the compensation light source (102) comprising laser of at least one color; and a rotating color wheel (103), comprising at least a first region (201) and a second region (202), wherein the first region (201) generates light of at least two different colors in time sequence under the irradiation of the excitation light in the first time sequence and the second time sequence, and the second region (202) is used for transmitting the compensation light in at least the third time sequence. The light of the at least two different colors comprises at least one type of wide-spectrum fluorescence, and the laser of the at least one color is used for compensating for the fluorescence or light split from the fluorescence. In this way, the compensation light is directly transmitted without being irradiated upon fluorescent powder, scattering loss of the compensation light is reduced, and utilization rate of the compensation light is increased.
