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.
