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.

An All-in-one LED lantern is a light device to determine the fairway of ships in operation. The current all-in-one LED lantern powered by solar energy is challenged by insufficient power capacity due to limited sun hours. This article presents an all-in-one 9-Nautical mile LED lantern driven by solar and wind power that is abundant maritime renewable energy. Furthermore, the remote smart monitoring system is developed. A smart control system capable of remote control of the lantern was implemented by using the LED lantern device and monitoring system as IoT. This technology that realtime condition monitoring and remote control are developed for safe ship navigation. We expect that maintaining the accuracy and consistency of LED lanterns prevents marine accidents and reduces social costs.

The usability of marine lantern has been improved significantly by using the LED bulb and applying IT technology, However it is hard to fix immediately when the failure occurs, and there would be some additional costs in maintenance. Therefore, alternatives for those problems are required. In this regard, in this paper, we proposed the integrated duel-function LED marine lantern that has main and auxiliary light source at the same time so that it can operate auxiliary light source when the main light source has breakdowns or malfunctions.

해상에 설치된 등부표에 등화를 밝히기 위해서는 전력 생산장비와 전력 저장장치가 필요로 하는데 등대 및 등부표에 사용하는 등명기는 현재 태양전지와 축전지 및 광원인 등명기를 각기 별도 설치하여 운영하여 등대 관리에 많은 시간과 예산이 소요되는 단점이 있어 국제적으로 전원일체형 등명기를 사용하는 추세이다. 재생에너지를 이용해 안정적인 전원을 공급받으며, 연안 수역을 운항하는 선박이 항로표지를 쉽게 식별할 수 있고, 해양사고 발생 시 긴급 수색 및 구조시스템 외에 침몰선박의 위치를 알려주는 기술을 연구 개발하였다.
