An electrically driven light emitting diode (LED) assembly comprising a light emitting diode (12), first (14) and second (16) electrical leads for conducting electricity to and from the light emitting diode (12), and a heat sink (18). The assembly is characterized by the first lead (14) including the heat sink (18) for conducting electricity and heat from the light emitting diode (12) through the heat sink (18). In other words, the diode (12) conducts electricity through a heat sink (18) allowing the diode (12) to be in electrical conductivity with the heat sink (18).

DETAILED DESCRIPTION AND ADVANTAGES An electrically driven light emitting diode (LED) assembly comprising a light emitting diode, first and second electrical leads for conducting electricity to and from said light emitting diode, and a heat sink.
The assembly is characterized by the first lead including the heat sink for conducting electricity and heat from the light emitting diode through the heat sink.
Also included in the invention is a method of fabricating such an electrically driven light emitting diode (LED) assembly comprising the step of disposing the heat sink in electrical series with the first lead for conducting electricity and heat from the light emitting diode through the heat sink.
Accordingly, the present invention comprises an LED assembly that is constructed with an integral primary heat flow path other than the electrical leads.
That heat flow heat sink may be electrically insulated on the outside of the LED when electrical isolation is required by coupling to an electrically conductive heat dissipater.
