LED Lighting Driver Circuit In Use Of Street Light Control System

Along with the rapid economic development, the power consumption subsequent is increased rapidly, so power has become scarce resources. A considerable part of the annual electric energy is consumed by the lighting of approximately 12% in China. However, power consumption by city-street-light system is also important not to neglect the part. The city-street-light system is an important component of a city, and its intelligence reflects the city’s modernization level. Therefore, the design of a high degree of automation, and operation of reliable, efficient energysaving, convenient to use the maintenance of LED lighting control system, modern street lighting system is an inevitable need. Therefore, the system which is highly automatic, reliable, efficient energy saving, convenient to use and supervise is designed.Giving a certain way of street LED lamps’energy saving and monitor system by fully utilizing wireless of GPRS communication and high-power LED lamps’Energy Saving, According to LED lighting features we have designed a distinctive LED driver circuit for the LED lights to provide the necessary current, voltage, and implemented the right LED lights over-temperature protection. The system collects real-time data, sends data to Internet by GPRS network, shows the street LED lamps’status parameters such as voltage, current, locates and alarms when finding unusual data, and sends warning. The system realizes the intelligent remote monitor, scheduling and management.LED lights Remote Data Transmission and Control have been realized, at the same time also have been realized automatic control. LED lights automatic control section includes:the part of LED street lamp light-controlled which use TWH8778 to design a light control switch; the part of LED street lamp temperature-controlled which can effective cool the LED lights; the part of LED street lamp time-controlled which can achieve automatic timed- controlling.
