A light source assembly includes: a plurality of point light sources; a beam composing composite prism including a plurality of light inlet surfaces, a plurality of dichroic planes, and a light outlet surface; and an optical integrator including a plurality of light reflecting planes forming a light guide path, a light inlet end corresponding to one end of the light guide path, and a light outlet end corresponding to the other end of the light guide path. In the light source assembly, the plurality of point sources are each disposed in contact with one light inlet surface of the beam combining composite prism, and the beam combining composite prism and the optical integrator are coupled to each other such that the light outlet surface of the beam combining composite prism and the light inlet end of the optical integrator are in contact with each other.
