摘要 固晶材料是超高亮度发光二极管(LED)封装过程中必备的关键材料之一,是决定LED性能,特别是寿命的重要因素。本文分别以银胶和绝缘胶为例,对比分析其对蓝、白光LED光学性能及光衰减过程的影响,在此基础上,提出一种评价和对比超高亮度LED性能优劣的算法,可以更可观准确地为LED封装设计和选材提供依据。 Die attach adhesive is one of the necessary key materials used for super light emitting diode （LED） package, and also is one of the important factors of deciding LED optical performance and life time. This paper provided the Comparison between Silver adhesive and insulated adhesive effected on optic performance and course of light degradation of blue and white LED, and furthermore, one evaluating and contrast method for super light LED performance is educed. This can be used for LED package design and materials selection more impersonally and exactly.
