Abstract

We review the current state-of-the-art in high-power (>1 W) GaN LED technology, and highlight current challenges in MOCVD epitaxy, device design, and high-volume manufacturing. We also describe recent developments in technology for high-power GaN-based LEDs which are operated beyond 5 W/LED with high efficiency (50 lm/W green, >30 lm/W white) and excellent reliability, and preview future challenges in solid state lighting and display applications.

用于照明和显示应用的大功率氮化镓基led
我们回顾了目前高功率(> 1w) GaN LED技术的最新进展,并强调了MOCVD外延,器件设计和大批量制造方面的当前挑战。我们还描述了大功率氮化镓基LED技术的最新发展,其工作效率超过5 W/LED,效率高(50 lm/W绿色,>30 lm/W白色),可靠性高,并预览了固态照明和显示应用的未来挑战。
