摘要

芯片级封装是实现高光密度白光LED和减小封装体积的一种重要途径，而目前芯片级白光LED存在荧光层老化、荧光粉热猝灭等问题，严重影响白光LED的性能和可靠性。为此，本文结合荧光玻璃的技术优势，提出了荧光玻璃封装芯片级白光LED，并分析了白光LED光热性能。利用丝网印刷和低温烧结工艺在玻璃基片表面制备了荧光玻璃层，从而获得了晶圆级荧光玻璃片，再切割成芯片级荧光玻璃用于白光LED封装。分析了荧光玻璃层的微观形貌，荧光粉颗粒内嵌在玻璃基体中，膜层致密、无明显残余气孔；通过调节荧光玻璃层厚度优化了白光LED光学性能，当荧光玻璃层为120 μm时，白光LED获得了最优光学性能，光效、色温和色坐标分别为111.8 lm/W、6 876 K和(0.307 4

0.321 4)；分析了荧光玻璃封装结构对白光LED光热性能的影响，荧光玻璃层靠近LED芯片封装具有更高的光效和更低的色温，同时白光LED表面温度更低。

Abstract

Chip-scale packaging(CSP) is an important way to realize a white LED with high optical density and reduce its package size. However

chip-scale white LED has the problems of the aging of phosphor layer and the thermal quenching of phosphor

which seriously affect the performance and reliability of white LED. Herein

combined with the technical advantages of PiG

we proposed a phosphor-in-glass(PiG) packaged chip-scale white LED

and analyzed the photothermal performance of white LED. The PiG layer was prepared on the surface of glass substrate with the process of screen printing and low-temperature sintering

and then the PiG was cut into the chip-scale PiG for white LED packaging. The microscopic morphology of PiG was analyzed. The phosphor particles were embedded in the glass matrix

and the film layer displays a dense structure with no obvious residual pores. The optical properties of white LED were optimized by adjusting the thickness of PiG layer. When the thickness of PiG layer is 120 μm

the related luminous efficiency(LE)

correlated color temperature(CCT)

and chromaticity coordinate are 111.8 lm/W

6 876 K

and (0.307 4

0.321 4)

respectively. The effect of PiG packaging structure on the photothermal performance of white LED was analyzed. The PiG layer close to LED chip packaging has higher LE and lower CCT

while the surface temperature of white LED is lower.
