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.
