摘 要
 
 本次畢業設計的主要任務是設計一個遙控型多彩LED燈箱控制器。LED有著高效、節能、環保等突出的優點，因此高能效的LED已經遍布工業化國家日常生活的各個角落。LED技術也越來越多地被應用于照明領域，任何城市的街道兩旁，不是門面就是店鋪，這些生意人都不惜代價，用各種醒目“LED電子燈箱”凸顯個性招攬客戶。燈箱的技術發展方向是：節能、方便、美觀。如果能同時實現這幾種功能，這將會是燈箱行業的一次革命。
 本次設計提出了一種基于STC單片機的LED燈箱控制方案，采用紅外遙控實現對LED燈箱的遙控控制。通過研究采用STC11F01單片機控制燈箱8種工作模式，通過IRF840 MOSFET驅動電路，12V→5V的降壓、穩壓電路進行供電。
 遙控型多彩LED燈箱控制器的出現就相當于出現了很大的方便，多彩的燈箱帶給人們多彩的心情。它將會給我們的LED燈箱用戶帶去更好的效益。

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.
