Patent ID: 8039862

Claim:
A white LED package comprising: a heat dissipation base; a plurality of electrodes disposed around the heat dissipation base; a supporter surrounding and fixing the heat dissipation base and the plurality of electrodes; at least two ring shaped protrusion structures protruding upward formed around a top surface of the supporter; at least one ring-shaped groove formed between the at least two ring-shaped structures; at least one LED die mounted on a top surface of the heat dissipation base; an encapsulation layer covering the LED die; a phosphor containing layer covering the encapsulation layer; and an optical lens layer covering the phosphor containing layer, wherein the at least two ring-shaped protrusion structures comprise first, second and third ring-shaped protrusion structures, and an outer edge of the encapsulation layer extends to the first ring-shaped protrusion structure, an outer edge of the phosphor containing layer extends to the second ring-shaped protrusion structure and an outer edge of the optical lens layer extends to the third ring-shaped protrusion structure, wherein the first, second and third ring-shaped protrusion structures have sharp top edges and tilted inner surfaces, and wherein the encapsulation layer, the phosphor containing layer and the optical lens layer have convex outer surfaces formed by surface tension at the sharp top edges of the first, second and third ring-shaped protrusion structures, respectively.
