摘要： 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

摘要： A single plate type projector has a DMD 3 and a rotary color filter 2. The DMD 3 converts light emitted from a lamp 1 into modulated light. The rotary color filter 2 separates the emission light from the lamp 1 into plural colors by rotating a rotary region which is interposed between the lamp 1 and the DMD 3 and on which light transmittance filter segments allowing each of different colors to pass are arranged. In such a projector, there has been a trade-off relation between the brightness of the entire image and color reproducibility because the amount of light of each color and the brightness of the entire image are restricted by the rotary filter. The amount of light emitting from the lamp 1 is controlled so that the amount of light increases during a period when the light emitted from the lamp 1 passes through at least one of the plurality of filter segments in the rotary color filter 2. Consequently, the brightness of the entire image and the color reproducibility can be arbitrarily regulated by regulating the quantity of light being emitted from the lamp 1.
