Patent ID: 7485480

Claim:
A method of manufacturing high power light-emitting device packages, comprising the steps of: (a) forming a plurality of lead frames on a metal strip, the lead frames mutually connected by tie-bars, each of the lead frames including a heat-dissipating element and a plurality of leads, and each of the leads outwardly extended from one side of the heat-dissipating element; (b) electroplating an outer surface of the lead frames each; (c) coating conductive gel on a surface of the heat-dissipating element of the lead frames each; (d) arranging at least one light-emitting chip on the conductive gel so that one bottom electrode of the at least one light-emitting chip electrically connected with the surface of the heat-dissipating element of the lead frames each; (e) forming an encapsulant on each of the lead frames by means of injection molding and the encapsulant covered on a portion of the heat-dissipating element and a portion of the leads each, a reflector cup integrally formed on the encapsulant and a reflective surface formed on an inner side wall thereof, and the at least one light-emitting chip exposed on a bottom of the reflector cups each; (f) connecting one top electrode of the at least one light-emitting chip with one of the leads by means of wire-bonding; (g) coating silver epoxy at wire-bonding connections; (h) coating silicon gel inside each of the reflector cups; (i) pressing a lens on a top of the reflector cups each; and (j) cutting off the tie-bars to separate the lead frames from one another, whereby forming a plurality of high power light-emitting device packages.
