摘 要
 
 本次毕业设计的主要任务是设计一个遥控型多彩LED灯箱控制器。LED有着高效、节能、环保等突出的优点，因此高能效的LED已经遍布工业化国家日常生活的各个角落。LED技术也越来越多地被应用于照明领域，任何城市的街道两旁，不是门面就是店铺，这些生意人都不惜代价，用各种醒目“LED电子灯箱”凸显个性招揽客户。灯箱的技术发展方向是：节能、方便、美观。如果能同时实现这几种功能，这将会是灯箱行业的一次革命。
 本次设计提出了一种基于STC单片机的LED灯箱控制方案，采用红外遥控实现对LED灯箱的遥控控制。通过研究采用STC11F01单片机控制灯箱8种工作模式，通过IRF840 MOSFET驱动电路，12V→5V的降压、稳压电路进行供电。
 遥控型多彩LED灯箱控制器的出现就相当于出现了很大的方便，多彩的灯箱带给人们多彩的心情。它将会给我们的LED灯箱用户带去更好的效益。

Abstract

 The main task of graduation is to design a remote control Multicolor LED Light controller. LED has the advantages of high efficiency, energy saving and environmental protection. So the energy-efficient LED has been around every corner of daily life in industrialized countries. LED technology is also increasingly being used in lighting, no city streets, not only façade but also a shop. To those who are at all costs, using a variety of eye-catching "LED Electronic light box," highlighting the personality to attract customer. The development of light box technology is energy saving, convenient and beautiful. If it achieves these types of functions together, it will be a revolution in the industry Light box.
 This design presents a single chip control scheme of LED lamp which is based on STC11F01 microcontroller , and uses infrared remote control to achieve remote control. After studying we used STC11F01 MCU to control eight modes，IRF840 MOSFET drive circuit and 12V → 5V step-down power supply regulator circuit.
 Remote Multicolor LED Light controller is equivalent to the appearance that there are great convenience .Colorful light boxes brought to people's colorful feelings. It will bring better benefit to the LED light box users.
