As a modern new type of lighting fixture, it has the advantages of small size, low energy consumption, long service life, and environmental friendliness. The LED array, control circuit, and driving circuit together form the LED lighting fixture, and the quality and service life of the LED lighting fixture are directly related to the performance of the LED driving circuit. The low power factor and low efficiency of LED driving circuits are the main shortcomings, which will cause harmonic pollution and reduce the utilization of electrical energy. To solve these problems, this design adopts a high-efficiency and high power factor LED driving circuit. In order to better utilize electrical energy, this design utilizes a single-chip microcomputer to achieve intelligent lighting, allowing the LED to achieve automatic control, and reasonable light adjustment will save more electricity. In the end, this design achieves the hardware of the LED intelligent lighting drive and control system, and the system runs well. The results show that all functions and parameters meet the requirements of this design.
