Description

A new method for evenly arranging LED circular fish-collecting lamp beads

technical field

The invention belongs to the field of light-baiting fishery equipment, and in particular relates to a novel LED circular fish-collecting lamp lamp bead uniform arrangement method that can improve the uniformity of water body illumination.

Background technique

Light trapping is an efficient way of using high-intensity artificial light sources to lure fish groups at night based on the principle of phototaxis of marine fish. Wait. The fish-collecting lamp is an important fishing aid equipment in light-baiting fishery. It mainly plays the role of attracting and collecting fish in the operation process. Its optical performance and its own structure directly affect the illumination distribution of the operation light field. Common traditional fishing lamps mainly include metal halide lamps, incandescent lamps and fluorescent lamps, etc., but there are problems such as low luminous efficiency, high fuel consumption, short service life, and high pollution. As the fourth-generation lighting source, LED lamps overcome the above traditional lamps. The shortcomings of the set of fish lamps have attracted great attention from various countries and regions since the introduction of fishery.

The power of a single LED lamp bead is limited, and it must be modularized in an array to meet commercial lighting needs. Due to the strong directivity of LED light, different module arrangements will inevitably affect the illuminance distribution of the illuminated surface, and appropriate light intensity and uniform illuminance distribution are the primary prerequisites for fish clusters. Therefore, choosing a suitable arrangement method of fish-collecting lamp beads is an effective way to improve fishing efficiency. At present, most of the LED circular lamps on the market are not evenly arranged in the lamp beads, which will cause uneven illuminance distribution and alternating light and dark in the water body during operation, which will not only reduce the efficiency of attracting fish, but also frighten and disperse the assembled fish. group. In addition, LED lamps will generate a lot of heat when working, and the uneven distribution of lamp beads will aggravate heat concentration in local areas, resulting in untimely heat dissipation and affecting the service life of fish-collecting lamps. Therefore, a reasonable and efficient LED fish-collecting lamp bead arrangement method is of great significance to improve the fishing efficiency, reduce input costs, and increase economic benefits.

The existing LED circular fish lamp lighting devices have various forms, and their internal lamp beads are arranged in different ways. The common ones are:

1) Consists of multiple light-emitting modules: such as Taiwan patents TWM488870U, TWI607174B, TWM548437U, TWM531136U;

2) It is composed of a whole flat circuit board: such as patent CN208237759U;

3) Cone type: such as patent CN304614827S.

The problems and disadvantages of the above three types of fish lights are as follows:

1) Multi-piece light-emitting module type: ① The light-emitting module is connected with the driver and each light-emitting module by a waterproof structure. The working conditions at sea are bad, which may easily lead to the aging of the waterproof rubber, and problems such as water ingress and leakage; ② The assembly line is complicated , the maintenance and repair costs are high; ③ There are gaps between the light-emitting modules, and the utilization rate of the circuit substrate is low;

2) The whole flat circuit board type: ① The lamp beads are not uniformly arranged, causing the water body to produce a phenomenon of light and dark with uneven light distribution, and the efficiency of attracting fish is low; ② The heat generation is uneven, the heat dissipation is not timely, and the service life is short;

3) Cone type: ① Strong light concentrating, concentrated illuminance, and small effective light-induced water body range; ② It is inconvenient for maintenance or replacement of parts.

At this time, there are more B ₂ lamp beads, and still need to continue to discharge; in order to ensure the uniformity of the lamp bead arrangement, it needs to be added again in i Randomly select ₂ circles of B in the circle, and place 1 lamp bead in each circle.

Further, first, establish a plane coordinate system: take the imaginary straight line as the x-axis, and vertically upward as the y-axis;

Define P(i, j) to represent any lamp bead located in the jth circle in the ith circle on the substrate, connect O'P, define the angle between it and the imaginary line as β, and obtain the formula:

Detailed ways

As shown in Figure 1, a new method for evenly arranging the LED circular fish lamp beads, defines the center of the circular circuit substrate as O', and the radius of the circular LED fish lamp circuit substrate to be designed is R. The number of lamp beads evenly arranged on the circuit substrate of the LED fish lamp is N.

All lamp beads are arranged around the O' point on the circular circuit substrate into a number of concentric lamp circles that are arranged at equal intervals from the inside to the outside. j, all the lamp beads in each circle are evenly distributed along the circumferential direction, and are sequentially arranged in a counterclockwise direction. In this embodiment, P(i, j) is used to represent any one of the jth lamp beads located in the ith circle on the substrate.

那么， 任意相邻两个灯珠的间距相等。Moreover, the distance between any two adjacent lamp beads in the same circle is equal to the distance between any two adjacent lamp circles, and r is defined as the distance between any two adjacent circles, and the formula is obtained:

Then, the distance between any two adjacent lamp beads is equal.

The first lamp beads of each circle are arranged on a horizontal imaginary line passing through the center O' with equal spacing r.

It is assumed that a total of N _i lamp beads are required to fill up i circles, N _i-1 pieces are needed to fill up i-1 circles, and N _i+1 pieces are needed to fill up i+1 circles. First of all, to determine the numerical value relationship between _Ni and N, the following three situations may occur.

The first case: when N _i =N, every turn is exactly full.

The second case: If N _i >N>N _i-1 , it means that N lamp beads can completely fill the first i-1 circle, but the i-th circle cannot be completely filled, define the difference between N _i and N It is dN ₁ , which means that when the i-th circle is arranged on the circuit board, the circle will have an excess of dN ₁ positions, and no lamp beads can be arranged. Therefore, it is necessary to randomly remove dN ₁ positions from all N _i positions on the substrate to achieve a uniform arrangement, which is carried out by the following formula:

dN ₁ =N _i −N (2);

B ₁ =dN ₁ -A ₁ *i (4);

In the formula: A ₁ represents the integer quotient of dN ₁ and i, B ₁ represents the remainder of the two, and B ₁ <i;

When removing, first remove A ₁ position in each circle, at this time, there are more B ₁ positions, and still need to continue to remove; in order to ensure the uniformity of the lamp bead arrangement, it needs to be randomly selected in the i circle when removing again. B ₁ circle, 1 position is removed in each circle.

The third case: if N _i <N<N _i+1 , it means that N lamp beads can completely fill the i circle, but cannot completely fill the i+1 circle. If the difference between N and Ni is dN ₂ , it means that when _i circles are filled on the circuit board, there will be extra dN ₂ lamp beads, and there is no place to arrange; The remaining dN ₂ lamp beads are randomly added to the existing i circle, and the following formulas are used in turn:

dN ₂ =NN _i (5);

B ₂ =dN ₂ -A ₂ *i (7);

In the formula: A ₂ represents the integer quotient of dN ₂ and i, and B ₂ represents the remainder of the two, where B ₂ <i;

When adding, firstly put A ₂ lamp beads in each circle. At this time, there are more B ₂ lamp beads, and still need to continue to discharge; in order to ensure the uniformity of the lamp bead arrangement, when adding again, it needs to be in i Randomly select ₂ circles of B in the circle, and place 1 lamp bead in each circle.

First, establish a plane coordinate system: take the imaginary line as the x-axis, and the vertical upward as the y-axis;

Define P(i, j) to represent any lamp bead located in the jth circle in the ith circle on the substrate, connect O'P, define the angle between it and the imaginary line as β, and obtain the formula:

Then, let the coordinates of any LED lamp bead P on the circuit substrate of the circular LED fish lamp be (x _p , y _p );

in:

x _p = i*r*cosβ (9);

y _p =i*r*sinβ(10);

Based on the above analysis, use MATLAB software programming to calculate the installation coordinates of each lamp bead, and evenly arrange N lamp beads on a circular circuit substrate with a radius of R.

In this embodiment, a total of 400 lamp beads need to be arranged in the LED circular fish lamp to be designed, and the effective radius of the circuit substrate is 100cm.

According to the principle of uniform arrangement of lamp beads in the present invention, it is known that 346 lamp beads are actually required for 10 circles on the circuit substrate, 415 lamp beads are required for 11 circles, and 490 lamp beads are required for 12 circles, so the circle The shape set fish lights should be arranged according to the method of the second case.

In this embodiment, the 11th circle cannot be completely filled with 400 lamp beads, and at this time, 15 positions need to be removed from the 415 positions. According to the calculation formula, firstly, one position should be eliminated in all circles, at this time there are still more than four positions. Randomly select 4 circles in 11 circles, and remove 1 position in each circle to meet the installation number. Since the redundant positions are removed randomly in this process, the uniform arrangement of all lamp beads on the circuit substrate is ensured to the greatest extent.

As shown in Figure 2, using MATLAB software to program this embodiment, the specific coordinates of 400 lamp beads can be quickly calculated, and the uniform arrangement diagram of the LED circular fish lamp lamp beads after the design is completed.

This embodiment has the following advantages: the specific installation position of each LED lamp bead on the circuit substrate can be set accurately, so that the lamp bead is arranged more evenly, the disadvantage of uneven heat dissipation of the substrate is overcome, the service life of the product is prolonged, and the The illuminance distribution in the water is more suitable, and the unevenness of the sea surface is avoided to the greatest extent, which is conducive to improving the efficiency of attracting fish.

In this embodiment, the LED fish light is composed of a light-emitting module and a driver, which is easy to assemble and saves time and labor.
