Deep sea high power led fish lamp

Abstract

The invention relates to underwater fish gathering lamps, in particular to a deep-sea high-power LED fish gathering lamp which comprises a high-power COB (chip on board) light emitting module, a water cooling passage and an underwater connector. The light emitting module comprises a lamp seat, COB light sources, Fresnel lenses and lens pressing plates, the water cooling passage comprises a cover plate, a hole plate, an upper plate and a lower plate, the lamp seat is a hollow polygon prism, the corresponding COB light source, the corresponding Fresnel lens and the corresponding lens pressing plate are fixed on each face of the polygon prism form inside to outside respectively, each COB light source is connected with a power source line through a guide hole in the lamp seat, a submarine cable is connected with the cover plate through the underwater connector to realize underwater sealing, the upper plate is arranged at the top of the lamp seat, the middle portion of the upper plate is hollow while the edge of the same is hollowed, the hole plate is arranged on the upper portion of the upper plate, the middle portion of the hole plate is hollow while the side face of the same is hollowed, the cover plate is arranged on the upper portion of the hole plate, sealing glue is coated on a matching face of the cover plate, the hole plate, the upper plate and the lamp seat, a lower concave cavity of the cover plate and the hole plate form a sealed cavity, the lower plate is arranged at the bottom of the lamp seat, the lower plate and the upper plate are fastened through screws, and the underwater connector is hermetically fixed on the cover plate.

Description

technical field [0001] The invention relates to an underwater fish-collecting lamp, in particular to a deep-sea high-power LED fish-collecting lamp. Background technique [0002] Traditional underwater fish-collecting lamps for light-lure fishing at sea mostly use metal halide bulbs as the light source, and the fuel consumption of fish-collecting lamps accounts for more than 30% of the total fuel consumption of the fishery. It has become a bottleneck restricting the development of pelagic fisheries. Because the metal halide lamp is a full-spectrum light source, when working under the ocean, about 90% of the luminous flux is absorbed by the seawater, and only about 10% of the blue-green light can be transmitted in the seawater, resulting in a great waste of energy. [0003] Chinese patent CN101329040 discloses a high-power blue-green light LED marine underwater fish-collecting lamp. In the lamp body, the upper end of the main housing is fixed to the upper housing, the upper ...

AI Technical Summary

Problems solved by technology

There are problems in this invention: 1. The fish-collecting lamp adopts corrosion-resistant aluminum alloy and surface plastic powder, which cannot solve the contradiction of seawater corrosion and heat dissipation of the fish-collecting lamp; 2. The LED module uses four blue and green lamp beads with a spacing of 30mm arranged alternately. It will inevitably lead to small power, large size, small luminous flux and small underwater irradiation distance of the fish-collecting lamp.
