Title: Illumination assembly with enhanced thermal conductivity

Abstract: Illumination assemblies include a substrate having a first and second electrically conductive layer separated by an electrically insulating layer. The insulating layer includes a polymer material loaded with thermally conductive particles. At least a portion of the thermally conductive particles simultaneously contact both the first and second electrically conductive layers. A plurality of light sources such as LEDs or other miniature light sources are preferably disposed on the first conductive layer.
