Underwater fish gathering lamp

Abstract

The invention discloses an underwater fish gathering lamp. The lamp comprises a lamp holder in the hollow tubular shape, wherein the inner ring surface defines a hollow flow channel, the plurality oflight source containing holes penetrate through the inner ring surface and the outer ring surface, and the plurality of convection holes penetrate through the inner ring surface and the outer ring surface and are communicated with the hollow flow channel. The diameter of the inner ring surface is D1, the diameter of the outer ring surface is D2, and the following relational expressions are met: D1 / D2 is more than or equal to 0.65 and less than or equal to 0.85; and a plurality of light source units, wherein each light source unit is arranged in each light source accommodating hole. Due to thefact that the lamp holder is designed to be in the hollow pipe shape, no internal and external pressure difference exists in the lamp holder, and the effect that the fish gathering lamp is resistant to pressure at the water depth of 300 meters is achieved. In addition, the relational expression not only can provide a pressure-resistant effect, but also can solve the problems that the structural strength is insufficient due to the fact that the lamp holder is too thin due to the too large ratio and the weight is too heavy due to the fact that the lamp holder is too thick due to the 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
