1. An LED based light source assembly comprising:

  • a circuit board comprising a first surface and a second surface opposite to the first surface, and electrical conductive traces formed on the first surface;

    a plurality of LEDs arranged on the first surface of the circuit board and electrically connecting with the electrical wires of the circuit board;

    a heat sink thermally contacting the second surface of the circuit board; and

    a plurality of fasteners each comprising a first end and a second end perpendicularly connected to the first end, wherein each of the fasteners comprises a metallic wire received in the first end and extending through the first end, the first end of each of the fasteners abuts on the first surface of the circuit board to make the metallic wires of the fasteners electrically connect with the electrical conductive traces of the circuit board, and the second end of each of the fasteners extends through the circuit board and is secured to the heat sink.
