Solar cells and LED lighting is a new energy and energy efficient technology, the typical application of solar aviation obstruction lights is a combination of the two products. The working principle of the system is: in the period of sunlight, the solar cells will be collected into the solar energy into electricity, under the control of the control system, the power stored in the battery pack, the lighting system needs electric power supply, to Lighting light source to provide safe and efficient voltage and current, so that LED lighting system safe, stable, efficient and reliable work for the traffic to provide clean and environmentally friendly green lighting Solar aviation obstruction lighting is the use of solar cells will be the nature of solar energy into electricity, providing light. Due to the low voltage, energy saving and long-term characteristics of LED light source, the application of solar lighting system will achieve high energy efficiency, reliability and practical value. The solar aviation obstruction lighting system consists of digital control drive systems including solar cells, converters and charge control, storage of energy storage battery and LED lighting PWM control drive and LED light source and other parts. 1, the battery pack Battery is an important part of the solar aviation obstruction lighting system, the battery management control not only affects the efficiency of the battery and the entire system, but also greatly affect the battery life. Usually concerned about the depth of discharge, the degree of charge and temperature and other three aspects. 2, converter According to the characteristics of solar photovoltaic cells, the control technology of solar aviation obstacle lighting control is analyzed and studied. The MPPT control method based on digital signal controller and DC / DC converter is proposed. Combined with the driving characteristics of high power LED lighting, An all-digital lighting control system with constant voltage constant current control performance, wide range of dimming capabilities, from multiple aspects to protect and improve the working condition. 3, control the drive system According to the characteristics of solar energy output and storage of solar photovoltaic cells and the progress of new technology driven by LED lighting control, a new control scheme of solar aviation obstacle lighting system is designed. The control scheme can realize MPPT charge and discharge management of solar cells and accumulators, LED lighting control drive management. It is because of the coordinated operation of the various systems, solar aviation obstruction lights to efficient and coordinated operation, to provide safe and stable navigation conditions to provide a guarantee.
