If you know something about the fishing industry, you should know that fishing by lure fish with lights is a very common method of operation, especially in offshore fisheries. The fish-gathering lamp is just an indispensable product in the light lure fish operation method. It mainly uses the phototaxis characteristics of the marine fish to lure fish through the light to catch the fish. The phototaxis of fish refers to the characteristic of the fish to produce a directional response to light stimulation.
If you know something about the fishing industry, you should know that fishing by lure fish with lights is a very common method of operation, especially in offshore fisheries. The fish-gathering lamp is just an indispensable product in the light lure fish operation method. It mainly uses the phototaxis characteristics of the marine fish to lure fish through the light to catch the fish. The phototaxis of fish refers to the characteristic of the fish to produce a directional response to light stimulation.
Earlier, the light source used in the fish traps of the light lure fishing industry was mainly metal halide lamps. Of course, it also had its shortcomings. That's why there is an opportunity for the emergence of LED light sources.
The technical indicators that use fish-gathering lights to affect the catch are as follows:
1. Light intensity
The intensity of light received by fisheyes is related to the depth of the water they live in, and the attenuation speed of sunlight at different water depths is different. The water quality, salinity, and granularity of different waters attenuate light and reach fisheyes of different depths. There is also a big difference in light quantum flux.
2. Spectral distribution
Seawater has significant differences in the attenuation of different spectral wavelengths of the light source. At the same time, different fish species are male and female, and their growth stages are different. The depth of water for living or eating is also different. Under normal circumstances, the propagation attenuation of the purple-blue band under seawater is relatively small. And, many fish also have different effective spectral wavelengths. For example, for squid, the most suitable fishing depth is 30-50 meters and the phototaxis of the waveband is used to rush to obtain the energy necessary for growth. The most suitable wavelength is 450-500nm.
3. Optical distribution
The shape of the fishing boat determines the optical distribution of the fish-collecting lighting system on the water to a certain extent. However, a reasonable and effective lighting system design can also greatly improve its catch. In addition, LED fish-collecting lights can not only provide suitable The wavelength, light quantum flux and the optimized optical distribution can also be provided through the intelligent control system to provide optical images with different graphics and moving speeds, strengthen the fish attracting effect, and increase the catch.
4. Weather resistance
Because the fish-gathering lamp needs to be installed on the fishing boat and work for a long time under extremely harsh environment, especially in the production operation under high salt fog environment, its working life and stability depend on the weather resistance and reliability of the product.
5. The light emitting surface and shape of the light source
The light-emitting surface and projection angle of the LED fish-collecting lamp are quite different from the traditional HID (metal halide lamp). The light effect and projection angle of the LED fish-collecting lamp are more suitable for fishing production, and the projection is farther and the fish is used more. The clustering effect produced by the phototaxis of the class.
6. Power and protective requirements of fish-collecting lamp products
The fish-collecting lights are installed on fishing boats, and the sizes of fishing boats vary greatly. The basic requirements are small and light, with high mechanical strength and protection. The environment of offshore operations changes greatly. Changes in temperature, humidity, salinity, wind speed, wind pressure, rain, fog, and storms require stable and safe installation of the fish lamp lighting system, and high maintenance-free requirements.
Under normal circumstances, the problem of projected light intensity can be solved by improving the light efficiency of the system, and the heat dissipation characteristics of the product can be optimized to extend its service life. At present, the domestic and foreign LED fish-collecting lamp products are a simple replacement idea of the metal halide fish-collecting lamp. The integrated high-power LED light source is used to replace the 1000W-1500W metal halide lamp with 800W LED lamps, which greatly improves the product system. Reliability and longevity.
7. The safety of the LED fish-collecting light product system
For most marine electricity, it is 380V electricity, so it is more dangerous to use; while the LED fish-collecting light adopts an integrated design and uses 220V input, which not only improves safety, but also eliminates cumbersome wiring problems, and also improves The reliability and stability of the product.
