The traditional Aids to Navigations(AtoN) have been ensuring the safety of ships by indicating the passage and dangers by depending on the flashing lights. But the more the industrial complex behind port which is all over the country involving the Ulsan port developed, the more the lights behind port is stronger, and then the distinguishment of the signal of AtoN from the lights behind port is more difficult. And It is urgently needed to prepare the counterplan about the ensurement of safety because the authorities levels up the limit tonnage of the ships which are sail in and out during night to improve the operation of port through reducing of the traffic jam So, the method of direct lighting like LED non-neon is applied to unmanned lighthouses or light beacon, and the LED flashing number plate is applied to light buoys whose light power is weaker than to improve distinguishment and to be easy positioning of ships. As a result, the users of Ulsan port comment favorably on this item and the development of AtoN must be continuos to overcome the lights behind port.

해양 교통안전을 위하여 해상에서선박에 필요한 정보를 제공하기 위하여 UN 등 국제규정에 의해 지시와 규제 및 안내표지판을 설치하고 있으며, 야간에도 항해선박에서 식별이 용이하도록 LED, 역반사재, 표시판의 조사 등 다양한 방법에 의해 식별을 강화하고 있으나, 항해자의 눈부심, 발광 빛의 번지는 형상, 전력의 공급 등 취약적인 요소가 나타나고 있는 실정이다. 이 연구에서는 해상에 설치되는 안전신호 표시판을 항해자가 보다 분명하게 식별할 수 있고, 해상에서 독립적인 전력을 획득하여 빌광할 수 있도록 연구 개발하였다.
