1. A radiation emitting device comprising:

  • at least one radiation emitter;

    first and second electrical leads electrically coupled to said radiation emitter; and

    an integral encapsulant configured to encapsulate said radiation emitter and a portion of said first and second electrical leads, said encapsulant having at least a first zone and a second zone, the second zone exhibiting at least one different characteristic from the first zone, wherein said at least one different characteristic is that said second zone has a higher thermal conductivity than said first zone, and wherein, in both said zones, said encapsulant is made of a material with a relatively high electrical resistivity.
