In unmanned lighthouse unmanned construction, it is necessary to establish a standardized system for efficient management and operation, and RTU standard protocols for condition monitoring and control are used to efficiently manage rotary lighters as the management system for the most important lighthouses. It is enacted to ensure the safety of maritime traffic through efficient management.

The advantages of LED(Light Emitting Diode) are low electric power consumption, long life time and excellent visibility. And a LED light source does not include the mercury(Hg) and or a filament, it is expected as an environmentally friendly next generation light source with its good reliability. In order to design and develope the flash lantern using LED for aironautical ground lights, technical trends and new standards about the aironautical ground lights were inspected, and power consumption and flash time for effective luminous intensity of aironautical ground lights were analyzed.

LED beacons operated on an isolated marine area are mostly employing the solar power supply system, and this system is well known for increasing the cost of management and maintenance. Recently, a number of researches and demonstrations on self-contained LED beacon is actively conducted to solve this issue. In this work, we propose an self-contained LED beacon with Bluetooth Low Energy function for an effective management of LED beacon. Firstly, control program structure is designed by expanding the status protocol of self-contained LED beacon, and then it is implemented into the form which administrator can easily understand. The control system visualizes the status and control data of self-contained LED beacon, and this enables the rapid decision-making of administrator. Also, minimizing electricity consumption of the beacon, it can transfer and update the status or light information of self-contained LED beacons with smart phone.
