White-light LED package structure with prefabricated fluorescent powder film

The invention provides a white-light LED package structure with a prefabricated fluorescent powder film, which consists of an optical lens 1, a fluorescent powder and caking agent prefabricated film layer 2, a chip 5 and a support with a hollow center 6, wherein the fluorescent powder and caking agent prefabricated film layer 2 is glued on the plane of the optical lens 1; the chip 5 is arranged on a central position on the bottom of the support with the hollow center 6; the optical lens 1 glued with the fluorescent powder and caking agent prefabricated film layer 2 and the support 6 are fixed together; and the caking agent is filled in the middle clearance between the optical lens 1 and the support 6. A white-light LED manufactured by the package structure improves the light-emitting consistency greatly, has stable optical parameters, shortens difference in the same batch or different batches greatly, and can improve the production efficiency. Because the fluorescent powder does not contact the chip directly, luminescence decay of the fluorescent powder caused by heating of the chip can be obviously reduced.
