3828蓝光,5050白光(light-emitting diode)已成为国际新兴战略产业界的竞争热点。在LED产业链中,上游包括衬底材料、外延、芯片设计及制造生产,中游涵盖封装工艺、装备和测试技术, 下游为LED显示、和灯具等应用产品。目前主要采用蓝光LED+黄色荧光粉工艺来实现白光大功率LED,即通过GaN基蓝光LED一部分蓝光激发 YAG(yttrium aluminum garnet)黄色荧光粉发射出黄光,另外一部分蓝光透过荧光粉发射出来,由黄色荧光粉发射的黄光与透射的蓝光混合后得到白光。蓝光发出的蓝光 透过涂覆在其周围的黄色荧光粉,荧光粉被一部分蓝光激发后发出黄光,蓝光光谱与黄光光谱互相重叠后形成白光。
