1. A light emitting device (LED) assembly comprising:

  • an electrically insulating substrate;

    a continuous thermally conductive layer adjacent a surface of the electrically insulating substrate;

    a light emitting device adjacent the continuous thermally conductive layer so that the continuous thermally conductive layer is between an entirety of the light emitting device and the electrically insulating substrate, wherein the continuous thermally conductive layer extends beyond an edge of the light emitting device in at least one direction a distance greater than half of a width of the light emitting device; and

    a plurality of thermally conductive vias through the electrically insulating substrate, wherein the plurality of thermally conductive vias are thermally and electrically coupled to the continuous thermally conductive layer and wherein portions of the electrically insulating substrate adjacent the light emitting device are free of the plurality of thermally conductive vias.
