Patent ID: 8344602

Claim:
A light source module comprising: a light emitting diode chip; a casting comprising a first surface, a second surface opposite to the first surface, and an outer peripheral side surface interconnecting the first surface and the second surface, the casting defining a receiving space concaved inwardly from the first surface thereof, the receiving space receiving the light emitting diode chip therein, and a through hole extending from the receiving space to the second surface; two metallic electrodes separated from each other, each of the metallic electrodes comprising a first terminal electrically connecting with the light emitting diode chip, and a second terminal disposed at the outer peripheral side surface of the casting; a heat sink filled in the through hole and thermally contacting the light emitting diode chip, the heat sink thermally and electrically insulated from the two metallic electrodes by the casting; a circuit board comprising an accommodating hole defined therein, and two elastic electrodes formed on an inner surface thereof surrounding the accommodating hole, the casting being completely received in the accommodating hole, the first surface of the casting being coplanar with a top surface of the circuit board, and the elastic electrodes abutting against the second terminals of the metallic electrodes, respectively; and a heat dissipation device thermally connecting with the heat sink and the second surface of the casting.
