Patents by Inventor HSIN-TUNG CHIANG

HSIN-TUNG CHIANG has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8455275
    Abstract: A light emitting diode package includes a substrate with a first metal layer, a second metal layer and an insulating layer between the first metal layer and the second metal layer. A cavity is defined in the insulating layer and the second metal layer. The second metal layer surrounding the cavity is divided into a first conductive portion and a second conductive portion. An LED chip is positioned inside the cavity and on an upper surface of the first metal layer. The LED chip has two electrodes electrically connected to the first conductive portion and the second conductive portion respectively. The cavity is filled with an encapsulation to cover the LED chip. A method for manufacturing the LED package is also disclosed.

  • Publication number: 20120094405
    Abstract: A method for manufacturing an LED package includes following steps: providing a substrate, wherein the substrate includes a plurality of package carriers and each package carrier includes two lead frames. Each package carrier includes a first surface and a recession surrounded by a bottom wall and a sidewall is defined on the first surface. Mount an LED chip on the bottom wall and electrical connecting the LED chip and the two lead frames, form an encapsulation in the recession; form a hydrophobic layer on the package carrier and the encapsulation; cut the substrate into a plurality of LED package structure.
