Fish lamp based on freeform surface with square spot

Abstract

The invention disclosesa fish lamp based on freeform surface with square spot, relating to a fishing equipment. The lamp solves the problems that the illumination spot of the existing fish lamp is circular in which the energy surface is uneven and the illumination is insufficient, and the fish lamp is failed to be compatible to the equipment with other shapes. The fish lampcomprises a LED chip, aheat sink, a lens cone, a cylindrical lens, a control panel, a lampshade, a fan and a housing.The light-emitting back surface of the LED chip is pasted on the front surface of the heat sinkthrough thethermalconductivesilica gel; the fan is arranged on the rear surface of the heat sink; the cylindrical lens is positioned at the front of the LED chip, wherein the lens is mounted to the coaxial front of the LED chip through the lens cone; the control board is arranged in the housingand is positioned at one side of the fan; the lampshade is arranged in the direction of the light emitted by the cylindrical lensand is used as the front end surface of the rectangular outer casing;The outer casing and the lampshade are pasted into an unibodystructure by the sealant. The fish lamp is applied totheautonomous cylindrical lens to achievethe deformation of the light spot and the rectangular illuminating surface satisfying the dimmingpreferenceof the fish groups for which the illumination is of uniform density with controllable brightness.

Description

technical field [0001] The invention relates to a fishing device, in particular to a fish-collecting lamp based on a square light spot on a free-form surface. Background technique [0002] Fish-collecting lights are the most important fishing aid equipment in light-baiting operations, and can be divided into two types: above-water lights and underwater lights. The water lights are mainly used to illuminate the area near the boat, and use the phototaxis of fish schools to light to make fish schools gather in our irradiation range for fishing to increase production. Fish-collecting lamps are currently the longest-used fishing technology in the fishery. In the prior art, the lighting spots produced by the current fish-collecting lights are all circular, but the lighting spots of the present invention realize rectangular lighting spots, and can realize a lighting surface with uniform energy. Contents of the invention [0003] In order to solve the problems that the existing ...
