ABSTRACT:
Disclosed herein is a package structure including at least one high power light-emitting diode to exhibit excellent heat release properties. In the package structure, a light-emitting diode chip which generates heat is directly attached to a beacon processed to protrude from part of a heat spreader having high heat conductivity, whereby an electrical wiring portion is separated from a heat release portion, thus maximizing heat release properties and realizing high luminance and reliability. The package structure is composed of a beacon formed on a metal or non-metal substrate having high heat conductivity to mount a high power light-emitting diode chip, to increase heat release properties; a wiring portion provided on the same line as the diode to input and output power and signals; and a reflection cup having a cavity, which may be inserted into or attached to the heat spreader or the wiring substrate, including a low temperature co-fired ceramic substrate, a high temperature co-fired ceramic substrate, or a printed circuit board.
