Patent ID: 6958250

Claim:
A method for encapsulating a light emitting diode, which comprises the steps of: a) placing a crystalline grains light-emitting diode chip into a pre-punched first lead frame; b) electrically connecting the first lead frame and the crystalline grains light-emitting diode chip to a second lead frame; c) encapsulating the crystalline grains light-emitting diode chip in a photosensitive polymer, the encapsulating step including placing the first lead frame, the crystalline grains light-emitting diode chip, and the second lead frame in a mold and injecting the photosensitive polymer into the mold; d) curing the photosensitive polymer at room temperature to form an encapsulated light emitting diode; and e) cutting, testing and packaging the encapsulated light emitting diode, wherein the photosensitive polymer utilized in the encapsulating step c) includes an Oligomer and a Photoinitiator, wherein the photosensitive polymer utilized in the encapsulating step c) includes at least one selected from the group consisting of between 0.1% and 20% of a Silane coupling agent, 0.01% and 15% of an ultraviolet absorber agent, and between 0.01% and 20% of a Hindered Amine Light Stabilizer.
