Radiation emitter devices and method of making the same
WO 2002061803 A3
Abstract
A radiation emitting device of the present invention includes at least one radiation emitter (35), first and second electrical lead (16-14) electrically coupled to the radiation emitter (35), and an integral encapsulant (12) configured to encapsulate the radiation emitter (35) and portions of the electrical leads. The encapsulant (12) has at least a first zone (30) and a second zone (32), where the second zone exhibits at least one different characteristic from the first zone. This different characteristics is one selected from the group consisting of mechanical strength, thermal conductivity, thermal expansion coefficient, specific heat, oxygen permeability, moisture permeability, adhesive strength, and trnsmittance. The radiation emitter is preferably a LED.
