Abstract:
1. An LED package structure for increasing heat-dissipating and light-emitting efficiency, comprising: a substrate unit having a substrate body, at least one first conductive pad, at least one second conductive pad and at least one chip-placing pad, wherein the at least one first conductive pad, the at least one second conductive pad and the at least one chip-placing pad are formed on a top surface of the substrate body; an alloy unit having at least one Ni/Pd alloy formed on the at least one chip-placing pad; a light-emitting unit having at least one LED chip positioned on the at least one Ni/Pd alloy of the alloy unit by solidified solder ball or glue; a conductive unit having at least two conductive wires, wherein the at least one LED chip is electrically connected to the at least one first conductive pad and the at least one second conductive pad by the at least two conductive wires, respectively; a package unit having a light-transmitting package gel body formed on the top surface of the substrate body to cover the light-emitting unit and the conductive unit; and a light-reflecting unit having an annular reflecting gel body surroundingly formed on the top surface of the substrate body by coating, wherein the annular reflecting gel body surrounds the at least one LED chip to limit the light-transmitting package gel body formed on the at least one LED chip.
