Each of the light source modules includes a first color light source and a wavelength conversion element. The first color light source is configured to provide a first color beam as an excitation beam. The wavelength conversion element is disposed on a transmission path of the first color beam and configured to convert the first color beam into a converted beam. The at least one condenser lens is disposed on transmission paths of the plurality of converted beams from the plurality of wavelength conversion elements and the plurality of first color beams.
