Light source module including light converging element

A light source module, comprising:

• a light source assembly, for providing an illumination beam;
• a light converging element, disposed on a transmission path of the illumination beam, the light converging element having a top end and a bottom end opposite to the top end, and being gradually reduced from the bottom end to the top end, wherein the top end is opposite to the light source assembly and has a cavity, the bottom of the cavity has a convex surface, and the illumination beam is incident into the light converging element from the cavity and exits the light converging element from the bottom end, wherein an angle distribution of the illumination beam after passing through the light converging element is smaller than 40 degrees;
• and
• a light uniforming element disposed between the light converging element and the light source assembly or disposed beside the bottom end of the light converging element.
