  • Publication number: 20140183570
    Abstract: The present invention provides an illumination apparatus. The illumination apparatus comprises a body having a lower portion coupled to a standard metallic lamp adaptor and an upper portion; a light source module comprising an LED array of LED chips connected in series, a phosphor powder layer encapsulating the LED chips, and a pair of conductive wires electrically connected to the LED chips for transmitting electric power to the LED chips; and a transparent housing coupled to the upper portion of the body, so that the LED chips are enveloped within the transparent housing.

  • Patent number: 8624489
    Abstract: The present invention relates to an LED die package, which has a light-emitting diode die having a sapphire layer, a first doped layer doped with a p- or n-type dopant, and a second doped layer doped with a different dopant from that doped in the first doped layer. A surface of the sapphire layer opposite to the surface on which the first doped layer is disposed is formed with generally inverted-pyramidal-shaped recesses and overlaid with a phosphor powder layer. Each of the first and the second doped layers has an electrode-forming surface formed with an electrode, on which an insulation layer is disposed and formed with exposure holes for exposing the electrodes. The exposure holes are each filled with an electrically conductive linker.

  • Patent number: 8563963
    Abstract: The present invention relates to a light-emitting diode die package. The LED die package includes a semiconductor base, at least two electrodes disposed on an electrode mounting surface of the semiconductor base, an insulation layer formed on the electrode-mounting surface and provided with two through holes for exposing the electrodes, a conductor-forming layer formed on the insulation layer and provided with two conductor-mounting holes in communication with the through holes, and conductor units formed within the through holes and the conductor-mounting holes in a manner electrically connected to the corresponding electrodes. The LED die package further includes a covering layer formed on a surface of the LED die opposite to the electrode-mounting surface and extending to an outer surface of the LED die. The covering layer is made of transparent material doped with phosphor powder.

  • Patent number: 8405099
    Abstract: The present invention relates to a light-emitting diode die package having an LED die and an accommodating housing. The LED die has a first doped layer doped with a p- or n-type dopant and a second doped layer doped with a different dopant from that doped in the first doped layer. Each of the first and second doped layers has an electrode-forming surface formed with an electrode, on which an insulation layer is formed. The insulation layer is formed with exposure holes for exposing the electrodes corresponding thereto. Each of the exposure holes is formed inside with an electrically conductive linker. The accommodating housing has an open end through which an accommodating space is accessible. The LED die is positioned within the accommodating space in such a manner that the electrically conductive linker protrudes outwardly from the accommodating space.
