摘要
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。
High-power GaN-based LEDs for lighting and display applications
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.
