Patent ID: 8440477

Claim:
A method for manufacturing an LED, comprising: providing a first electrode, a second electrode and a Zener diode, and electrically connecting the Zener with the first electrode and the second electrode; providing a mold, the mold comprising an upper die and a bottom die, the bottom die defining a receiving groove in a top surface thereof, the upper die comprising a core component and a wall around the core component, the core component defining a notch in a bottom surface thereof; putting the first electrode, the second electrode and the Zener diode in the receiving groove of the bottom die, the core component of the upper die being put on the first and second electrodes, the Zener diode being received in the notch of the core component, the wall of the upper die being put on the bottom die, the wall surrounding and being spaced from the core component, a sprue being defined between the core component and the wall; injecting a liquid molding material into the receiving groove of the bottom die through the sprue, until the receiving groove, the notch and the sprue are filled with the liquid molding material; solidifying the liquid molding material and removing the upper die and the bottom die from the solidified molding material to integrally form a base, a dam and a reflective cup, the solidified molding material in the receiving groove of the bottom die forming the base, the solidified molding material in the sprue forming the reflective cup, the solidified molding material in the notch of the core component forming the dam, the Zener diode being encapsulated in the dam; setting a first LED chip on the first electrode and a second LED chip on the second electrode and electrically connecting the first and second LED chips with the first and second electrodes; and forming an encapsulation layer in the reflective cup to encapsulate the first and second LED chips.
