    • A surface mounted LED packaging structure based on a silicon substrate includes the silicon substrate, an LED chip, an annular convex wall and a lens. The silicon substrate has an upper surface of planar structure and without grooves. An oxide layer covers the upper surface of the silicon substrate. Metal electrode layers are arranged in the upper surface of the oxide layer, and the upper surfaces of the metal electrode layers are arranged with metal bumps. Vias through the silicon substrate are provided under the metal electrode layers. An insulating layer covers the inner wall of the vias and a part of the lower surface of the silicon substrate. A metal connection layer covers the insulating layer surface within the vias. Two conductive metal pads are respectively arranged under the lower surface of the silicon substrate and insulated from the silicon substrate. A heat conduction metal pad is arranged on the lower surface of the silicon substrate. The LED chip is flip-chip mounted on the silicon substrate. The annular convex wall and the lens cause the LED chip and the metal electrode layers therein to be isolated from environment. The structure of the present invention has its advantages of good heat dissipation effect and small volume, while packaging without gold wires makes the structure highly reliable and achieves large-scale production of wafer level, resulting in the reduction of the packaging cost.
