Abstract (en)
[origin: WO02061803A2] A radiation emitting device of the present invention includes at least one radiation emitter, first and second electrical leads electrically coupled to the radiation emitter, and an integral encapsulant configured to encapsulate the radiation emitter and a portion of the first and second electrical leads. The encapsulant has at least a first zone and a second zone, where the second zone exhibits at least one different characteristic from the first zone. Such different characteristics may be a physical, structural, and/or compositional characteristic. Preferably, the at least one different characteristic includes at least one of the following: mechanical strength, thermal conductivity, thermal capacity, coefficient of thermal expansion, specific heat, oxygen and moisture impermeability, adhesion, and transmittance with respect to radiation emitted from the radiation emitter. The radiation emitter may be in a form of an emitter, and is preferably an LED.
[origin: WO02061803A2] 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.
