摘要：
A light-emitting diode with an improved service life is provided. The diode is formed from a transparent outer shell that contains a heat-resistant encapsulant at least partially surrounding a light-emitting diode clip. The first encapsulant is compressed between the outer shell and a second encapsulant when it is sealed into the outer shell by the second encapsulant.
