Research on High-precision Intelligent PWM Optically Controlled LED Road Illumination Drive Power Supply

Considering the traditional LED road illumination drive power supply existence some shortcomings,such as the illuminance can not be adjustable, output current constant poor accuracy and so on. Therefore this paper design a high-precision intelligent PWM optically controlled LED road illumination drive power supply,which use the fuzzy control algorithm can automatically adjust power output drive current according to ambient light, and achieve LED optically controlled, then improve power efficiency and save energy.The experimental results show that the design has very good characteristics of LED road illumination intelligent optical ly controled, highprecision output constant current, strong adaptability, stable and reliable performance.
