Study On The Control System Of The LED Energy Saving Lamps For The Complementary Scenery Of University

With the gradual depletion of oil resources and people's demand for new energy sources,energy conservation and emission reduction have become a hot spot of research.Currently,most colleges and universities use the corridor lights are "all night Constant Brightness" way of lighting,causing serious waste.In response to this situation,this study was designed Universities wind and solar LED energy control system.Firstly,this arcicle discussed the function and the overall scheme design of the control system of the LED energy saving lamp,which is a complementary system of the University's scenery,and makes a detailed analysis of the system's hardware and software.In terms of hardware,the intelligent controller PIC16F877A to intelligent control systems for solar power,wind power systems and LED lights,use MPPT algorithm to track the maximum power of the system to realize the solar panels and wind turbines to generate electricity maximum utilization.By Boost boost circuit,and combined with the maximum power tracking strategy,thereby effectively charging the battery using PWM pulse width modulation technology to adjust the LED light intensity.In the battery discharge portion,combining LED load characteristics,design a reasonable strategy discharge system,was developed based on the constant-current source Buck switching power supply driving circuit,overload current protection circuit and voltage detection circuit.The intelligent control software was designed to realized the charge control,PWM diming control and real-time control of the battery.The system function was simulated and the simulation results show that the design scheme is feasible.Experiments show that it can significantly improve the street corridor electricity efficiency and saving energy for the scenery complementary energy-saving LED street lamp control system,so the system has to promote the use of value.
