Underwater fishing lights

Abstract

The invention discloses an underwater fish-collecting lamp, which comprises: a lamp base, which is in the shape of a hollow tube, and has an outer ring surface, an inner ring surface defining a hollow flow channel, and a plurality of light sources running through the inner and outer ring surfaces. Holes, and a plurality of convection holes that pass through the inner and outer rings and communicate with the hollow flow channel, so that the diameter of the inner ring is D1, the diameter of the outer ring is D2, and the following relationship is met: 0.65≦ D1 / D2≦0.85; and a plurality of light source units, each light source unit is arranged in each light source accommodating hole. Since the lamp base is designed as a hollow tube, there is no pressure difference between the inside and the outside of the lamp base, so it can provide the pressure-resistant effect of the fish-collecting light at a water depth of 300 meters; in addition, the relationship can not only provide the pressure-resistant effect , and at the same time solve the problems that the lamp holder is too thin and the structural strength is not enough due to too large ratio, and the problem that the lamp holder is too thick and heavy due to too small ratio.

Description

technical field [0001] The invention relates to the field of fish-collecting lamps, in particular to an underwater fish-collecting lamp. Background technique [0002] As the fish light system is widely used in fishery, besides the power output, many problems arise. At present, the mainstream fish-collecting lights all emit light on the fishing boat to attract fish, and a few designs can emit light at the operating depth of the fishing boat within a depth of 50 meters underwater. [0003] According to the degree of light transmission, seawater can be divided into transparent layer and opaque layer. The light-transmitting layer refers to the area where the light on the surface of the water body can reach when the water body is irradiated by sunlight, and algae or plankton can perform photosynthesis. The depth of the light-transmitting layer is affected by the water quality of the water body. In chaotic water bodies, the light-transmitting layer May be less than 1 meter; in c...

AI Technical Summary

Problems solved by technology

[0005] At present, there are very few underwater fish-collecting lights on the market that emit light beyond 50 meters underwater. In addition, even if there are fish-collecting lights that exceed 50 meters in water depth, the power is only a few hundred watts or the light-emitting distance is about 10 meters. Unable to achieve the purpose of attracting fish at a depth of 300 meters
