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. The conductive passage electrically couples the second portion of the conduction board and the portion of conductive layer, which is insulated from the connection layer.
