A light source module includes a casing, a light-guiding rod, a light-emitting assembly and a heat-dissipating reflective shroud. The casing has a chamber and a transparent opening in communication with the chamber. The light-guiding rod has a light-exiting surface and a light-transmitting surface opposite to the light-exiting surface. The light-guiding rod is disposed in the chamber with the light-exiting surface facing the transparent opening. The light-emitting assembly is provided on one side of the light-guiding rod to emit light toward the interior of the light-guiding rod. The heat-dissipating reflective shroud is assembled with the casing to cover the light-transmitting surface of the light-guiding rod. The interior of the heat-dissipating reflective shroud has a reflective surface for reflecting the light passing through the light-transmitting surface back toward the light-exiting surface to exit the transparent opening. The heat-dissipating reflective shroud has double effects of heat dissipation and light reflection.
