摘要
通过利用创新生产制作的纳米稀土荧光粉(YAG)作为二次封装光转换材料,能够产生面发光的发光体,有效提高LED照明灯具的视觉舒适度,降低光生物危害指标值以及解决LED照明的富蓝光和眩光问题.本研究研制的LED二次封装光转换结构荧光罩(板、膜)具有良好的耐温性能和较强的抗老化性能,提供行业内二次封装光转换的评价体系.
Adopting the nanosized YAG(Yttrium Aluminum Garnet)phosphoras the raw material of a white LED lamp secondary encapsulation structure is able to form a surface light source,enhance euphoropsia,reduce the biological hazard,and solve the problems about excess blue light and glare.The as prepared white LED lamp secondary encapsulation structure has good temperature tolerance and ageing resistance and provides an evaluation system for the optical conversion performance of the secondary encapsulation structure.
