Patent ID: 7053421

Claim:
A light-emitting diode comprising: a surface mounted package comprising: a substrate having a first surface and a second surface; two composite metal layers insulated from each other and respectively extending from the first surface to the second surface, each of the composite metal layers having a copper layer positioned on the substrate and a silver layer positioned on the copper layer; a light-emitting diode chip electrically connected to the composite metal layers on the first surface; and a sealing member covering the light-emitting diode chip and adhering to a portion of the substrate and to a portion of each composite metal layer; a printed circuit board; and two solder paste layers respectively covering portions of the composite metal layers for electrically connecting the printed circuit board to the composite metal layers on the second surface; wherein the silver layers are utilized for preventing the solder paste layers from penetrating into space between the sealing member and the composite metal layers and for reflecting light beams generated by the light-emitting diode chip.
