1. A light source module, comprising:

  • a printed circuit board including a first surface, a second surface opposite to the first surface, and a plurality of through holes penetrating through the first surface and the second surface;

    a heat-dissipating assembly located adjacent to the second surface of the printed circuit board, the heat-dissipating assembly including a base, a plurality of heat-conducting elements, and a plurality of heat dissipation fins, the base defining a third surface and an opposite fourth surface, the third surface defining a plurality of cavities therein, the heat dissipation fins extending from the fourth surface and along a direction away from the third surface, each of the heat-conducting elements being inlaid in a corresponding cavity defined in the third surface, each of the heat-conducting elements thermally contacting with the base; and

    a plurality of light emitting elements each being placed in a corresponding through holes of the printed circuit board and being thermally contacted with a corresponding heat-conducting elements, each of the light emitting elements being electrically connected with the printed circuit board, each of the light emitting elements defining a light emitting surface located outside the corresponding through hole and being directed away from the second surface of the printed circuit board.
