The Design Of Solar LED Street Light Controller

With economic development and social progress, people raised higher and higher energy demands, finding new energy has become an urgent issue facing humanity, while solar energy is a huge, long endless energy. Use of solar energy include solar light and heat utilization, solar photovoltaic and solar energy use photochemical use. In recent years the use of solar PV is the fastest growing, most dynamic area of research is also the most dynamic area of research. As the LED's operating current is DC, and a lower operating voltage. Solar cells convert light into direct current energy, and solar cell components can be obtained by series and parallel combinations of voltage the actual needs. These characteristics match exactly with the LED, a combination of both will be very high utilization, high security, energy saving, environmental protection, safe and efficient lighting system.Solar street lamp solar street lamp system controller is the important part, but also with the biggest difference between street light system where the. How the performance of the controller determines the operation of a PV system's strengths and weaknesses. Therefore, the design functions, simple structure of intelligent solar street lamp controller is very important.This issue is based on SCM's solar LED street lamp STC12C5410AD controller design. Mainly discusses the battery charge and discharge control technologies and solar panel maximum power point tracking (MPPT) technology.After introducing the principle of the controller designed the corresponding hardware and software flow, and are given in an appendix at the end of the machine circuit and the corresponding procedures.
