摘要
隨著單片機控制技術(shù)的發(fā)展和LED的廣泛應(yīng)用。目前我們在街道上看到的燈好多都是LED燈泡，比如我們見到的交通燈；高樓周圍的彩燈；娛樂場所的變色燈等等。這些都是采用了現(xiàn)階段比較流行的LED燈。它不但省電節(jié)約能源而且照明強度高，只有很少的一部分會轉(zhuǎn)換為熱能。
鑒于LED應(yīng)用廣泛，在此次畢業(yè)設(shè)計中我們提出了基于單片機控制技術(shù)上的變色燈的制作，該燈就是LED燈。通過做此次畢業(yè)不但可以使我們對LED的基本原理、特點及其常見的應(yīng)用等有了一定的了解，而且也了解了變色的原理。通過用單片機做控制寫代碼也鞏固了我們大學(xué)所學(xué)的單片機課程。通過此次畢業(yè)設(shè)計使大家對LED燈有了初步認(rèn)識、增加學(xué)習(xí)物理、應(yīng)用物理的興趣。

Abstract

Along with monolithic integrated circuit control technology development and LED widespread application. At present we saw on the street the lamp many are the LED light bulbs, for instance we saw traffic light; Around tall building colored lantern; The recreation areas change color light and so on. These have used the present stage quite popular LED lamp. Not only it the province electricity saves the energy moreover the illumination intensity to be high, only then a very few part can transform into the heat energy. In view of the fact that LED applies widely, we proposed in this graduation project changes based on the monolithic integrated circuit control technology in the color light the manufacture, this lamp is the LED lamp. Not only through made this graduation to be possible to cause us to the LED basic principle, the characteristic and the common application and so on had certain understanding, and has also understood the color deterioration principle. Through used the monolithic integrated circuit to make the control to write the code also to consolidate the monolithic integrated circuit curriculum which our university studied. Made everybody through this graduation project to have the preliminary understanding to the LED lamp, to increase the study physics, the application physics interest.
