Professor Xiong’s Lecture: The existing LED fishing lamp promotion method ：Government support, investment exploration
The LED fishing lamp experiment ship of Yangjiang’s light cover net boat (the experiment started in 2013, the second generation was installed in 2014, and the third generation was installed in 2015) the 1000w metal halide lamp of the whole ship was replaced by 500w led fishng lamp. In 2015, Institute of Engineering Thermophysics of Chinese Academy of Sciences and other Marine light purse Seine sea trial, and has passed the test and even identification.
Weizhi received financial support of more than 2 million yuan, and engineering thermal physics Institute and other units received total financial support of nearly 10 million yuan.
This is the first type of fish lantern promotion: government support, investment exploration. The government supports enterprises, universities and research institutes to jointly promote the development of Led fishing lights industry. The reason is that LED fish lamp replaces gold halide lamp with high energy consumption, which is indeed a good thing to benefit the country and the people. This support can help drive the development of some new technologies, but if the benefits are not clear, or if some technologies are not up to snuff, the subsequent push will be difficult.
We also know that Weizhi has developed the fourth generation of LED fishng lamps and launched them into the market. Some people in the engineering thermal physics Institute are also promoting LED fish-collecting lamps with micro-slot group complex phase change heat dissipation, but the effect is not ideal. I’m not sure about the effect of the LED fish lamp in the sea trial of the Institute of Engineering thermal physics. The situation of Wei Zhi is relatively clear. Because the third generation lamp wants to replace the metal halide 1000w fishing lamp comprehensively, the LED lamp should be hung high, trying to reduce the weight of the radiator, so the heat dissipation is not up to the standard, resulting in the light decline of the lamp. In more than one year after the assembly of the lamps, the fish catch using the LED fishing lamp system can be basically the same as that using the metal halide lamp system before, saving oil. However, due to the large attenuation of light, the brightness is obviously not enough in the third year. In the fourth year, we removed the LED fish lamp and replaced it with a gold halide lamp. When a fisherman sees that the experimental boat (or advertising boat) does not use 500w green fishing light, will he still dare to use them?
It is said that the difficulties encountered by the LED fishing lights with microslot group compound phase change heat dissipation are the same as Weizhi.
