Claim 3:
4. A light source system comprising:
a first light emitter configured to emit a first light with a first color band in a first time interval of a time period;
a second light emitter configured to emit a second light with a second color band in a second time interval of the time period rather than in the rest of the time period other than the second time interval; and
a light guide disposed downstream from the first light emitter and the second light emitter;
wherein the first time interval and the second time interval overlap in an overlapping time interval, the first light emitter and the second light emitter synchronously emit the first light and the second light in the overlapping time interval to form a combined light beam in the light guide, and the light with the second color band is dominant of the combined light beam;
the first light emitter does not emit the first light in the rest of the time period other than the first time interval, the first time interval consists of the overlapping time interval and a non-overlapping time interval, and the light source system further comprising:
a phosphor wheel comprising:
a wavelength conversion area disposed in an optical path of the first light emitted from the first light emitter in the overlapping time interval, wherein the first light becomes a photoluminescence after reflected by the wavelength conversion area; and
a first reflection area disposed in the optical path of the first light emitted from the first light emitter in the non-overlapping time interval, wherein the first light becomes a first reflected light after reflected by the first reflection area; and
a color wheel comprising:
a first color filter disposed in an optical path of the first reflected light so that the first light filters therethrough into the light guide; and
a second color filter disposed in an optical path of the second light and an optical path of the photoluminescence so that the second light and a filtered light with the second color band filter therethrough into the light guide.
