An improved LED lead frame packaging assembly includes a thermally conducting, electrically insulating material that enhances the thermal conduction and structural integrity of the assembly, a UV-resistant encapsulantmaterial, and an integral ESD material that reduces electrostatic discharge. The thermally conducting, electrically insulating material creates an electrically insulating, thermally conductive path in the lead frame assembly for dissipation of power and also acts as a mounting structure thus allowing for the use of a soft encapsulant material, preferably a silicone.
