Abstract:
1. A high-power LED package structure, comprising: a lens; a lamp shade cup; a light-emitting diode (LED) chip array used as a light source having at least one LED chip; a metallic heat sink on which said LED chip array is embedded having a volume much larger than said LED chip array, a top surface of said metallic heat sink further including said lamp shade cup covered with said lens, said lens having a preset curvature for projecting light in a predetermined angle; and a heat-conducting base on which said metallic heat sink is mounted, a heat-conducting insulating layer being disposed between said heat-conducting base and said metallic heat sink, whereby mechanical toughness, electric insulating and heat conduction of said high-power LED package structure will be enhanced; whereby the heat generated in said LED chip array will be quickly transferred to said metallic heat sink and then to said heat-conducting base, and whereby said LED chip array will support a higher electric current and have brighter light intensity; and wherein an upper rim of said lamp shade cup is provided with a depressed flange, and a lower rim of said lamp shade cup is provided with an annular inner surface; said lamp shade cup having a downwardly contracting curved surface; and wherein said metallic heat sink is further provided with a central platform whose upper surface being a supporting surface for said LED chip array; said supporting surface being further provided with a pair of through holes each for passing through a bracket, which brackets are extended out of a bottom surface of said metallic heat sink; said brackets being connected to metallic wires that are connected to said LED chip array.
