Design and performance estimation of fish-luring system using the water cooling typed LED lamp

A fishing lamp is fishing gear to gather fish in the night. But the cost of oil which is used to a light fishing lamp,goes significantly up to almost one hundred million won for 50 tonnage vessels and forty million won in case ofvessels less than 10 tonnages. This cost has almost taken 30–40% of total fishing costs. As oil price increases, thebusiness condition of the fishery gets worse and worse. Therefore, it is very urgent to develop an economicalfishing lamp, to solve the problem of fishery′s business difficulty. This research aims at developing a fishing lampfor squid jigging fishery and hairtail angling fishery using the LED, which has excellent efficiency and durability.One fishing lamp has about 160Watt capacity and five fishing lamps are installed one aluminium panel in whichsea water flows to emit generated heat from LED to outside. Developed fishing lamp lights to an effectivedirection of jigging and angling operation. This fishing lamp can be controlled to light the direction of fish shoalbecause the aluminium panel can be controlled to up and down direction. The wave length of fishing lamp haswhite and blue color. White color light is to gather fish shoal of horizontal direction and blue color light is togather fish shoal of vertical direction. After development of this fishing lamp, 60–110 units are established on theboat, and operated fishing. Consequently, in the case of squid jigging, spent energy was reduced to 39%, in thecase of hairtail angling, 68% of spent energy was reduced. And the catch was more than another boat.Keywords: LED fishing lamp, Squid jigging, Hairtail angling
