LED as a modern new lighting fixtures and facilities, which combines the advantages of small volume, low power consumption, long service life and environmental protection in a body. The LED array, control circuit and drive circuit which is composed of three parts ofLED lamp, which is directly related to driving circuit of LED lamp quality and lifewith LED. So in the design of LED driving circuit design will be very important. Now the LED drive circuit power factor is low and the low efficiency is the main shortage, which would cause harmonic pollution and reduce energy use. In order to solve these problems, the design will take the high efficiency and high power factor LED drive circuit. In order to better use of electric power, this design will useintelligent lighting, enables the LED to achieve automatic control, reasonable light adjustment will be more save electricity. Finally, the complete design of the intelligent lighting control and drive the hardware of the system, and the system is running well, the results show that the functions and parameters can meet the requirements of the design. Keywords: LED; single chip microcomputer; switching power supply; intelligent lighting 毕业设计说明书(论文)外文摘要 Title Microcontroller-based intelligent LED lighting and drive systems Abstract : LED ( light-emitting diode ) is a semiconductor diode , is capable
