什么是led封装

菅 08-10 02:57

LED封装是指发光芯片的封装，相比集成电路封装有较大不同。LED的封装不仅要求能够保护灯芯，而且还要能够透光。所以LED的封装对封装材料有特殊的要求。

简单讲就是给发光二极管芯片穿的“衣服”。封装具有保护芯片不受外界环境的影响和提高器件导热能力的作用。此外更重要的作用是提高出光效率，并实现特定的光学分布，输出可见光。希望我的回答能帮助到你

韶音若逝 08-10 03:14

LED封装技术大都是在分立器件封装技术基础上发展与演变而来的，但却有很大的特殊性。一般情况下，分立器件的管芯被密封在封装体内，封装的作用主要是保护管芯和完成电气互连。
