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) The whole flat circuit board type: ①The lamp beads are not evenly arranged, which causes the water body to produce light and dark phenomena with uneven light distribution, and the fish luring efficiency is low; ②The heat production 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, and 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 light bead located on the j-th in the i-th circle on the substrate.
[0044] Moreover, the dist...

Abstract
The invention provides a new method for evenly arranging lamp beads of LED circular fish-collecting lamps. All lamp beads are arranged on a circular circuit substrate around a central reference point to form a number of concentric lamp rings arranged at equal intervals from inside to outside. All the lamp beads in each circle are evenly distributed along the circumference; and the distance between any two adjacent lamp beads in the same circle is equal to the distance between any two adjacent light circles. It can accurately set the specific installation position of each LED lamp bead on the circuit substrate, and make all the lamp beads be evenly arranged, so that the illuminance distribution in the water is more suitable, and the phenomenon of uneven light and shade on the sea surface can be avoided to the greatest extent, which is beneficial to Improve the efficiency of fish luring, overcome the disadvantage of uneven heat dissipation of the substrate, and prolong the service life of the product; the circuit substrate of the same size can be equipped with more lamp beads, and the space utilization rate increases, which is conducive to reasonably increasing the power of the fish-collecting lamp and quickly determining the installation of the lamp beads The location saves the time of lamp bead positioning and illumination calibration, high efficiency and strong practicability.
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. The fish collecting light is an important fishing aid equipment in the light lure fishery. It mainly plays the role of luring and collecting fish in the operation process. Its optical performance and its own structure directly affect the illumination distribution of the operating light field. Common traditional fishing lights mainly include metal halide lamps, incandescent lamps and fluorescent l...
