Problems solved by technology
[0009] 1) Multi-block light-emitting module type: ①The light-emitting module is connected with the driver and each light-emitting module with a waterproof structure. The offshore operation condition is harsh, which may easily lead to aging of the waterproof rubber, water ingress, leakage and other problems; ②Complicated assembly lines , high maintenance and repair costs; ③ there are gaps between the light-emitting modules, and the utilization rate of the circuit substrate is low;
[0010] 2) Whole planar circuit board type: ①The lamp beads are not evenly arranged, causing the water body to produce light and dark phenomena with uneven light distribution, and the fish luring efficiency is low; ②The heat generation is uneven, the heat dissipation is not timely, and the service life is short;
[0011] 3) Cone type: ①Strong light concentration, concentrated illumination, and small effective light-induced water range; ②It is not easy to maintain or replace parts

Embodiment Construction
[0042] Such as figure 1 As shown, a new method of evenly arranging LED circular fish-collecting lamp lamp beads, defining the center of the circular circuit substrate as O', the radius of the circuit substrate of the circular LED fish-collecting lamp to be designed is R, in the circular LED fish-collecting lamp The number of lamp beads evenly arranged on the lamp circuit substrate is N.
[0043] All the lamp beads are arranged around the O' point on the circular circuit substrate to form a number of concentric lamp circles arranged at equal intervals from the inside to the outside. The number of circles arranged by the lamp beads is set to i, and the number of lamp beads in each circle is j, All the lamp beads in each circle are evenly distributed along the circumference, and arranged sequentially in a counterclockwise direction. In this embodiment, P(i, j) represents any certain lamp bead located on the j-th in the i-th circle on the substrate.
[0044] Moreover, the distan...

Abstract
The invention provides a novel LED circular fish gathering lamp bead uniform arrangement method. All lamp beads are arranged on a circular circuit substrate around a center reference point to form a plurality of concentric lamp rings arranged at equal intervals from inside to outside, and all the lamp beads in each ring are uniformly distributed in the circumferential direction; and the distance between any two adjacent lamp beads in the same ring is equal to the distance between any two adjacent lamp rings. The specific installation position of each LED lamp bead on the circuit substrate canbe accurately set, and all the lamp beads are in a uniform arrangement state, so that the illumination distribution in water is more suitable, the phenomenon of uneven brightness of the sea surface isavoided to the maximum extent, the fish luring efficiency is improved, and meanwhile, the defect of uneven heat dissipation of the substrate is overcome, and the service life of a product is prolonged; and more lamp beads can be assembled on the circuit substrate with the same size, so that the space utilization rate is increased, the power of the fish gathering lamp can be reasonably improved, the installation positions of the lamp beads can be quickly determined, the lamp bead positioning and illumination calibration time is saved, the efficiency is high, and the practicability is high.
Description
technical field [0001] The invention belongs to the field of light-lure fishery equipment, and in particular relates to a method for evenly arranging lamp beads of a new LED circular fish-collecting lamp that can improve the uniformity of illumination of a water body. Background technique [0002] Light-trap fishing is based on the principle of phototaxis of marine fish. It is an efficient operation method to use high-intensity artificial light sources to trap fish schools at night. Common light-trap saury nets, light-trap squid fishing, light seine nets, and light cover nets Wait. Fish-collecting lights are important fishing-aiding equipment in light-lure fishery. They mainly play a role in luring and collecting fish during operation, and their optical performance and structure directly affect the illumination distribution of the operating light field. Common traditional fishing lights mainly include metal halide lamps, incandescent lamps and fluorescent lamps, etc., but t...
