- Ship-Rolling Motion Adaptive LED 집어등 시스템의 개발에 관한선행 연구
This paper presents a preliminary study on the development of a Light-Emitting Diode (LED) fishing lamp system that can maintain a stationary irradiation region despite ship rolling motions. The proposed system is composed of three modules which include a main control module, a fishing lamp module, and a sensor module. The main control module collects both the operating condition setting of the fishing lamp via the input panel and the tilt angle information of a fishing boat from the sensor module. It provides the conditions and information to the fishing lamp module for controlling the LED modules that maintain a stationary irradiation region. One fishing lamp module is composed of 22 LED modules, a lamp controller, and a temperature sensor. The sensor module is used for measuring the tilt angle of the fishing boat. Tests were carried out to verify the reliability of the LED module driver and the sensor module. The tests showed that the LED modules were reliably controlled, in accordance with the rolling motion of a fishing boat.
