A sea-fishing operation test in Xisha sea area for 300W multi-COB (Chip on Board) LED fish luring lamp obtained a great success after a whole month of August this year. The technical and energy-saving specifications of the lamp reach the international advanced level. The research and development of this product was hosted by the Institute of Engineering Thermophysics, Chinese Academy of Sciences (IET), and jointly performed by the Institute of Semiconductors, the Institute of Electrical Engineering, and Shenzhen Institutes of Advanced Technology of Chinese Academy of Sciences. The R&D work was financially supported by “300W LED Fish Luring Lamp R&D”, one of the Projects supported by the “Cuicanxingdong” Semiconductor Lighting R&D Program of Chinese Academy of Sciences.
For a fishing boat, the electric energy for sailing and lighting is powered by a marine diesel generator. Traditionally, the metal halide lamp is used for light-purse seine fishing, which is with the minimum power of 1000W for single lamp. Usually, hundreds of metal halide lamps are installed on a fishing ship. It leads to huge electrical energy consumption. Apparently, fishing time and quantity are all seriously limited. The 300W multi-COBLED fish luring lamp is primarily designed by using Micro-grooves Combined Phase-Change Cooling Technology, which is developed by IET. Small size, high luminous efficacy, low energy consumption and excellent ability to lure fish are characteristic of the lamp. It has an epoch-making significance in extending fishing time and production.
The 300W multi-COB LED fish luring lamp was designed as side-lighting with total luminous flux of 30000 lumens. Its total weight is less than 2 kg and its volume is also smaller than a typical 1000W metal halide lamp. Long lifetime and high lumen maintenance are realized by highly efficient cooling and by using special optical lens to make the greatest amount of luminous flux emitting from the LED source refracted into the seawater. Then, its irradiation area, irradiation distance and effective average are superior to traditional 1000W metal halide lamp. Furthermore, the 300W LED lamp has an outstanding performance in penetrating sea fog and seawater.
For the sake of comparison test, twenty-eight 300W multi-COB LED fish luring lamps were installed on each side of the fishing ship with the original two hundred 1000W metal halide lamps remained in their places. Light-luring purse seines fishing was conducted for several times under the different lighting conditions of the two kinds of lamps separately. The final result shows that fishing production quantity for single net increases from 2000kg to 4000kg when using LED lamps lighting. It means that the light of LED lamp is more attractive to marine fish. And, it is obvious that a fishing boat will save more than 70% electrical energy for light-luring illumination when 1000W metal halide lamp is placed with 300W LED lamp.
The sea-fishing operation test has proved the excellent performance and good application effect of 300W multi-COB LED fish luring lamp in real sea-fishing environment. In the near future, as an aggregation of four original technologies of Chinese Academy of Sciences, the LED fishing lamp will enter the phase of batch production and marketing with a strong competition. According to incomplete statistics, the market size of LED fish luring lamp in Hainan province is more than 20 billion Yuan. Considering other sea areas in China, the data will exceed 100 billion Yuan. In addition, the development and application of the LED fish luring lamp will greatly promote the development of light-purse seine sea-fishing with significant social and economic benefits.
