1. A semiconductor radiation emitter package comprising:

  • a heat extraction element;

    at least two electrical leads having a greater thermal resistance than said heat extraction element;

    at least one semiconductor radiation emitter mounted on a first surface of said heat extraction element, wherein when said at least one semiconductor radiation emitter is activated, the semiconductor radiation emitter package emits white light; and

    an encapsulant covering said at least one semiconductor radiation emitter, at least a portion of said encapsulant being substantially transparent to wavelengths emitted by said at least one semiconductor radiation emitter, said encapsulant material covering a portion of the first surface of said heat extraction element, while leaving exposed at least a portion of a second surface of said heat extraction element that is opposite the first surface, the exposed portion of the second surface being directly opposite an area of the first surface where said at least one semiconductor radiation emitter is mounted.
