A light source module including a light source assembly and a light converging element is provided. The light source assembly provides an illumination beam and the light converging element is disposed on a transmission path of the illumination beam. The light converging element has a top end and a bottom end opposite to the top end. The light converging element is gradually reduced from the bottom end to the top end. The top end is opposite to the light source assembly and has a cavity. The illumination beam is incident into the light converging element from the cavity and exits the light converging element from the bottom end. The illumination beam is converged by the light converging element, so the diverging angle of the illumination beam provided by the light source module is relatively small.
