Dual LED lantern, which is composed of two light sources in one lantern, can be utilized as an auxiliary light source when the main light source is in trouble. Nevertheless, there are no way to obtain status information of the system and control the light source if the current domestic standard protocol is applied, since the standards for dual LED lantern are not defined yet. Regarding to this problem, we suggested expanded lantern protocol for management system of dual LED lantern based on current domestic standard. Also, we confirmed the normal operation of dual LED lantern after implementing suggested protocol on the developed management system. Control system suggested and implemented in this study is tested not only its function of controlling and acquiring the operating status of dual LED lantern, but also its capability to utilize as a control system of currently used LED lanterns.

A high light lantern system using LEDs is composed of power supply, flash controller, and daylight controller and proper case considering work condition. The performance of developed LED lantern is better than that of the existing marine lantern using an incandescent electric lamp and that of foreign products(Vega LED lantern made in New Zealand, Tideland system made in America). The electric consumption of our products is 30% compared with that of existing marine lantern using an incandescent electric lamp, and the luminous Intensity of them is 200% to 400% compared with that of existing marine lantern and foreign LED lantern. In addition, our LED lantern system is easy to repairing something wrong and changing the LED module and other controllers on the sea when they are in accident.

The advantages of LED(Light Emitting Diode) are low electric power consumption long life time and excellent visibility. In order to design and develope the marine lantern using LED, technical trends and standards about the marine lantern were analyzed and sample products were manufactured and evaluated in comparing with existing marine lantern The performance of developed LED lantern is better than that of the existing marine lantern using an incandescent lamp. The electric power consumption of our products is 30[%] and the luminous intensity is two or fen times brighter than existing marine lantern.

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.

The initial light emitting diode (LED) has been used as a display device for various mechanical devices due to its low power. The development of LED technology has made it possible to express color with high power and high brightness. Therefore, it is used as a display such as a traffic signal, a large electric signboard, and an automobile display, and is also adapted as an indoor or outdoor light source such as an incandescent or a fluorescent lamp which requires the high luminance. The bulb of marine lantern, which is used for the aids to navigation, was replaced to LED. The first marine LED lantern was manufactured using multiple LEDs. However, if the optical design is renewed by the development of LED or even if a few LEDs are used, it is possible to satisfy the brightness and the light distribution required by the marine LED lantern.

Advances in IT technology and modernization of AtoN(Aids to Navigation) facility has increased the unmanned operation of AtoN. However, in AtoN facilities, accessibility is low and it is not able to perform maintenance on the bad weather at the time. In connection with this, in this paper, by applying the protocol of the enhanced dual LED marine lantern, we implemented the short-range monitoring system for a mobile terminal. System implemented in this paper can be carried out confirm the operation status, inspection or control of the dual LED marine lantern at a short distance. Also, it is possible to reduce maintenance costs and prevent accidents during inspection of AtoN. At the same time, it enables the operation test easily without disassembling the product, effective AtoN operation is possible. We tested the system that has been implemented using prototype of the LED marine lantern and confirmed state informations and controlled the behavior of the system in real time.

The synchronous flash of a marine lantern, differentiated from the flash pattern of other risk indicators, supports the safe sailing of vessels. General marine lanterns flash according to the flash protocol through sensing the day and the night. Thus, there can be time error over time and the marine lantern does not synchronously flash as a whole. To resolve this problem, this study designed LED marine lantern based on constant-current system using synchronous flash technique enabling all marine lanterns to keep its time based on GPS satellite time. Also we suggested a radiation method with an effective heat emission performance in the restricted and closed space of a marine lantern.

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.
