摘要
LED芯片作为一种新的光源,在国内开创了巨大的新兴市场,其应用越来越广。介绍了LED光柱显示器替代仪表指针的应用情况,结合其制作与应用进行了讨论。LED光柱自身发光,色彩丰富,并具有抗过载、抗振动、平均无故障工作时间在5万小时左右等特点,是仪表显示方式一个新的飞跃。
As a new type of light source,LED has been developed a huge market in China. Its application scope almost spreads all over cities and enterprises. The instrument industry also came into a new stage of substitution of the pointer indicator for simulation LED bargraph.This paper discussed and expounded about the replacement of instrument pointer indicator by LED bargraph simulation graph combining our practice. Owing to the selflight, rich color, high resistance to overloading and vibration and as long working time as 50 000～80 000 h, it has an unexampled advantage compared with instrument pointer indicator and other bargraph, and is a new step in instrument indicate manner.
