A light source system and a projection system, comprising a light source (30); a switching system (40,60) switching light emitted by the light source (30) into at least two light beams (λ1, λ2, λ3, λ4) having a preset proportion in the manner of time division or light intensity division; a color wheel assembly (50, 70) located in a transmission light path of each light beam of the at least two light beams (λ1, λ2, λ3, λ4), with the color wheel assembly (50, 70) generating light having different colors and a preset proportion under the irradiation of each light beam of the at least two light beams (λ1, λ2, λ 3, λ 4), and light of different colors being able to synthesize a projection image after being modulated by a light modulation system, wherein the switching system (40, 60) can adjust the proportion of the at least two light beams (λ1, λ2, λ3, λ4) according to the parameters of the projection image, so as to adjust the proportion of the light of different colors. Once an offset of a white balance occurs on the projection image, the proportion of light beams of different colors can be adjusted by adjusting the proportion of the switched light beams, so as to achieve the white balance again, so that it is not necessary to replace same with a new color wheel, thereby solving the problems of relatively high costs and relatively large usage difficulty of the projection system. |
