基于单片机LED旋转屏设计

Design of LED Rotating Screen Based on MCU

随着半导体材料以及工艺技术的提高,生产量的增加,和科学技术及工艺水平的提升,LED灯的性能进一步地提高。它随着产品价格的不断逐步提高和价格下降,使它将渐渐的可以进入千家万户,给我们的家居生活环境带来一个安全节能,明亮的新生活光源。led这种绿色环保日光灯的节电效率几乎相比普通绿色白炽灯几乎可以做的节电效率高达80%以上,led这种绿色环保日光灯的使用寿命几乎可以是普通绿色白炽灯的光管的10倍以上,它们几乎都可以做的完全是免费电维护,不过我们还是需要经常的使用更换普通白炽光的灯管,镇流器,启辉器等产品来彻底解决这些问题,绿色环保日光灯主要是绿色环保型的一种绿色日光半导体工业照明专用光源,它的主要特点之一是照射光线柔和,光谱纯,有利于绿色日光灯对有害人体和眼睛视力的长期保护和有害植物微生体的健康。将采用单片机处理器控制的led流水灯显示设备稍作一些改进,让它更加灵动起来,就是因为它能神奇地在屏幕上显示各种的字符或图案,其视觉效果如同鱼漂浮在空中一般。之所以能如此,这主要得益于一种人眼的"视觉暂留"的现象,我们可以把它称之为pov(persistenceofvision)。这种LED旋转技术可以运用在各种邻域,如广告设计,酷炫屏幕设计等。

With the improvement of semiconductor materials and technology, the increase of production, and the improvement of science and technology, the performance of LED lamp is further improved. With its price decreasing, it will gradually enter thousands of households and bring us new energy-saving and bright light sources. Compared with incandescent lamp, LED fluorescent lamp can save more than 80% of energy, and its life span is more than 10 times that of ordinary lamp. Almost all of them are maintenance free and do not need to replace lamp, ballast, starter and other problems frequently. The green and environmental semiconductor light source has soft light and pure spectrum, which is conducive to the protection of human vision and health. The LED running water lamp controlled by single chip microcomputer is slightly improved to make it move, which can magically display various characters or patterns, and its effect is like floating in the air. The reason for this is due to the phenomenon of "visual persistence" of human eyes, which we call POV(persistence of vision). This led rotation technology can be used in various neighborhoods, such as advertising design, cool screen design, etc.
