一种新型高效的多层荧光粉层白光LED封装结构
摘要
The applications of white light-emitting diodes (LEDs) have become more and more wide recently, while the low light-extraction efficiency of white LED limits its development. In this letter, a new structure of multilayer phosphor package of white LED is proposed to improve the light-extraction efficiency. It is illustrated that the thickness of phosphor layer plays an important role in improving the light-extraction efficiency of LED. The light-extraction efficiency of LED is improved by double-layer or multi-layer phosphor package structures.
