Abstract
The laser source includes a light-emitting assembly, a phosphor wheel, a converging lens group, and a combining component. The light-emitting assembly is configured to emit at least a first laser beam and a second laser beam. The phosphor wheel includes a fluorescence-exciting region and a laser-reflecting region. The converging lens group is disposed between the light-emitting assembly and the phosphor wheel, and is configured to converge the first laser beam and the second laser beam to the phosphor wheel. The first laser beam and the second laser beam are asymmetric with respect to an optical axis of the converging lens group. The combining component is disposed between the light-emitting assembly and the converging lens group. The combining component includes a first reflecting region and a second reflecting region that are arranged at an interval.
