Light emitting device and production method of same

Abstract

A light emitting device, and a production method thereof, is provided having for a light source thereof a vertical geometry light emitting diode, that allows a large current to flow through the vertical geometry light emitting diode and takes into consideration the dissipation of heat occurring at that time or the expansion and contraction of a metal member due to thermal stress caused by that heat. The light emitting device at least comprises a package having a plurality of mutually separated package electrodes; a vertical geometry light emitting diode having a light emitting layer positioned between a p-type semiconductor layer and an n-type semiconductor layer, an upper partial electrode of the uppermost layer, and a lower electrode of the lowermost layer, wherein the lower electrode is joined onto one of the package electrodes; and, a conductive connecting member that connects the upper electrode of the vertical geometry light emitting diode with another of package electrodes; wherein the junction between said one of the package electrodes and the lower electrode, the junction between the upper electrode and the conductive connecting member, and the junction between the conductive connecting member and said other of package electrodes are made with solder.
