由于基质材料的开发以及亮度的提高,LED的应用范围正在扩大。目前,对于LED的主要技术要求是提高各种颜色,特别是蓝色LED的亮度。LED的另一技术要求是改善LED在发光强度和光色方面的均匀性,以及在室外应用时适应气候变化的性能。LED应甩的增加是由于其亮度的改善。1968年,LED被首次采用,最初是用作指示灯,以后,LED则用作功能部件一办公室自动化设备的光源、遥控器件以及照相机自动聚焦器件等。十九世纪八十年代中期,超高亮度红色LED被开发出来,使得LED的应用扩展到诸如新闻发布显示板、交通信息显示板,铁
Due to the development of matrix materials and the increase of brightness, the application range of LED is expanding. At present, the main technical requirements for the LED is to improve the brightness of various colors, especially the blue LED. Another technical requirement for LEDs is to improve the uniformity of LEDs in terms of luminous intensity and light color, as well as to adapt to climate change when used outdoors. LED should be thrown because of its brightness improvement. In 1968, LEDs were first introduced and were initially used as indicator lamps. Later, LEDs were used as functional parts - a light source for office automation equipment, remote control devices, and auto-focusing devices for cameras. The mid-1980s, ultra-high brightness red LED was developed, making LED applications extended to such as news release display panels, traffic information display panels, iron
