Abstract
A light-emitting diode (LED) structure with an improved heat transfer path with a lower thermal resistance than conventional LED lamps is provided. For some embodiments, a surface-mountable light-emitting diode structure is provided having an active layer deposited on a substrate directly bonded to a metal plate that is substantially exposed for low thermal resistance by positioning the metal plate at the bottom of the light-emitting diode structure. This metal plate may then be soldered to a printed circuit board (PCB) that includes a heat sink. For some embodiments of the invention, the metal plate is thermally and electrically conductively coupled through several heat conduction layers to a large heat sink that may be included in the structure.
