Abstract
A solid-state light source has light emitting diodes embedded in a thermally conductive translucent luminescent element. The thermally conductive translucent luminescent element has optically translucent thermal filler and at least one luminescent element in a matrix material. A leadframe is electrically connected to the light emitting diodes. The leadframe distributes heat from the light emitting diodes to the thermally conductive translucent luminescent element. The thermally conductive translucent luminescent element distributes heat from light emitting diodes and the thermally conductive translucent luminescent element.
