Description

Underwater fishing lights

The present invention relates to a fish collecting lamp, and particularly refers to an underwater fish collecting lamp.

With the increasing popularity of fish-collecting light systems in fisheries, in addition to power output, many problems have arisen. At present, the mainstream fish-gathering lights are used on fishing boats to emit light and attract fish. A few designs can emit light at the working depth of the fishing boat within 50 meters.

According to the degree of light transmission, sea water can be divided into a light-transmitting layer and a matte layer. The light-transmitting layer refers to the area where light from the surface of the water body can reach when the water body is irradiated by the sun, and the area where algae or plankton can undergo photosynthesis. The depth of the light-transmitting layer is affected by the water quality. In a chaotic water body, the light-transmitting layer It may be less than 1 meter; in clean water, it can reach 50 meters to 100 meters, or even 200 meters. When the depth reaches 200 meters, the visible light has been almost completely absorbed. The "illuminated area" within 200 meters is called the translucent layer in oceanography. The depth of more than 200 meters can be called a matte layer. However, the fish schools may not always operate at a depth of 50 meters underwater, so even if the power of the fish-collecting lights on the water exceeds one kilowatt, they cannot effectively attract fish in the matt layer.

Each drop of 10 meters in the sea water will increase the water pressure by one atmosphere. To attract fish at a depth of 300 meters, the underwater fish light must be able to withstand a water pressure of 30 atmospheres and prevent the pressure from causing sea water to leak into the light and cause damage.

At present, there are very few underwater fish lights on the market that emit light more than 50 meters underwater.
