  • Publication number: 20060027829
    Abstract: A package structure of a light emitting diode includes a substrate structure, a connection layer, and at least one conductive passage. The substrate structure sequentially includes a conduction board, an insulation layer, and a conductive layer. The insulation layer is configured to electrically insulate the conduction board from the conductive layer, and also to insulate a first portion from a second portion of the conduction board. The substrate structure has an opening to expose the conduction board. The connection layer configured to support and electrically couple to a first electrode of a light emitting diode (LED) is disposed in the opening. The connection layer is also configured to electrically couple to the conduction board and to be electrically insulated from at least one portion of the conductive layer, which is coupled to a second electrode of the LED.

  • Publication number: 20050274971
    Abstract: A light emitting diode (LED) and a method of making the same are disclosed. The present invention is featured in that the LED comprises a transparent heat-conductive glue, a reflective layer, and a carrier, etc, wherein the transparent heat-conductive glue is used to adhere the epitaxial structure and the carrier of the LED; the reflective layer can make the light emitted by the epitaxial structure to be reflected more efficiently; and the carrier is used to enhance the heat-dissipation effect of the LED. Moreover, the transparent heat-conductive glue and the reflective layer can be replaced with one single adhesive reflective layer having functions of adhesion and reflection simultaneously.
