A dissipation module for a light emitting diode includes a substrate, a printed circuit board, and a heat sink. The substrate has electrode sheets on which the light emitting diode is electrically mounted. The printed circuit board includes an upper surface and a bottom surface. The printed circuit board defines plated through holes passing from the upper surface to the bottom surface, and mounts on the substrate with the bottom surface in contact with the upper surface. The heat sink connects to the bottom surface of the printed circuit board through a conductive layer.
