人类社会伴随着时光的流淌,总在不断地向前。在这个前进过程中,科技日新月异的发展起到了不可或缺的作用。新发明、新发现在推动人类社会前进的同时,也让人们的生活更加舒适、便利。比如照明工具。从油灯到电灯,经历了漫长的历史时期,电灯的出现极大地促进了人类的文明进步。而2014年诺贝尔物理学奖表彰了科学家在发明新型高效节能光源方面的贡献,这种新型光源即蓝色发光二极管。现在各种电视晚会、大型演出活动的炫目灯光效果都离不开LED。为什么是蓝光LED?它是如何为人类带来照明技术革命的?详见本期
With the flow of time, human society always keeps moving forward. In this course of progress, the rapid development of science and technology has played an indispensable role. New inventions and new discoveries promote the progress of human society and at the same time make people’s lives more comfortable and convenient. Such as lighting tools. From oil lamp to electric lamp, has experienced a long historical period, the emergence of electric lamps has greatly promoted the progress of human civilization. The 2014 Nobel Prize in Physics honored scientists in the invention of new and energy efficient light source contribution, this new light source that blue light-emitting diodes. Now a variety of television shows, dazzling performances of large-scale performances are inseparable from LED. Why is the blue LED? How does it bring the lighting technology revolution for mankind?
