Abstract:
1. A light-emitting diode die package, comprising: a light-emitting diode die having a sapphire layer, a first doped layer disposed on the sapphire layer and doped with a p- or n-type dopant, and a second doped layer disposed on the first doped layer and doped with a different dopant from that doped in the first doped layer, wherein a surface of the sapphire layer opposite to the surface on which the first doped layer is disposed is formed with a plurality of generally inverted-pyramidal-shaped recesses, and wherein each of the first doped layer and the second doped layer has an electrode-forming surface formed with an electrode; a phosphor powder layer disposed on the surface of the sapphire layer formed with the recesses; an insulation layer disposed on the electrode-forming surfaces and formed with a plurality of exposure holes for exposing the electrodes corresponding thereto; a plurality of electrically conductive linkers, each being formed within one of the exposure holes; a support plate having a supporting surface, on which conductive contacts are disposed; a heat-dissipating film layer overlaid on the supporting surface of the support plate and formed with at least two through holes that communicate between an upper surface and a lower surface thereof, wherein the light-emitting diode die is secured to the heat-dissipating film layer, so that the electrically conductive linkers are electrically connected to the conductive contacts of the support plate via the corresponding through holes provided in the heat-dissipating film layer; and a circular seat, placed on the heat-dissipating film layer, so that the light-emitting diode die is located at a central portion of the circular seat.
