摘要
随着单片机控制技术的发展和LED的广泛应用。目前我们在街道上看到的灯好多都是LED灯泡，比如我们见到的交通灯；高楼周围的彩灯；娱乐场所的变色灯等等。这些都是采用了现阶段比较流行的LED灯。它不但省电节约能源而且照明强度高，只有很少的一部分会转换为热能。
鉴于LED应用广泛，在此次毕业设计中我们提出了基于单片机控制技术上的变色灯的制作，该灯就是LED灯。通过做此次毕业不但可以使我们对LED的基本原理、特点及其常见的应用等有了一定的了解，而且也了解了变色的原理。通过用单片机做控制写代码也巩固了我们大学所学的单片机课程。通过此次毕业设计使大家对LED灯有了初步认识、增加学习物理、应用物理的兴趣。

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.
