LED应用于显示技术的案例

目前，LED灯的电光转化效率比UHP灯低，如果亮度输出不能快速提高，用于投影的前景堪忧。UHP灯效率（60~70lm/w）提高基本无余地，但LED灯效率提高的潜力还很大，其推动力不是投影之类的特殊应用，乃是绿色节能照明的巨大需求。节能是我国和世界各工业国家的基本国策，中国有绿色照明工程，美国有半导体照明国家研究项目，日本制定了“21世纪照明”发展计划，欧盟正在开展多色光源的“彩虹计划”，韩国也有“固态照明计划”。 LED灯从日用照明向特殊照明的转移应用，投影光源顺带受益。
LED灯发光效率的前景由美日韩制定了时间表，这是一张性能快速增长的表格。2002~2007五年间增长2.5倍，达到75Lm/w，已经赶上UHP；2002~2010八年间增长4倍，达到120 Lm/w，超过UHP；以后还会提高到UHP根本达不到的150，200 Lm/w。<o:p></o:p>
因此，可以断定LED投影灯的未来之路是光明的。<o:p></o:p>

It's nice!
LED illumination must have a great future.
