LIGHT-EMITTING DIODE WITH LOW THERMAL RESISTANCE

摘要

A light-emitting diode (LED) structure providing an improved heat transfer path with a lower thermal resistance than conventional LEDs without significantly deviating from the conventional dimensions is described. For some embodiments, a light-emitting diode structure is illustrated that includes a lead frame that is substantially exposed for low thermal resistance by positioning it on the bottom of the light-emitting diode structure. An LED semiconductor chip is electrically and thermally conductively connected to at least one lead of the lead frame for external connection. In some embodiments, a lens or transparent cover plate may cover the LED structure to alter the properties of the emitted light.
