Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of LED lamp panel design, in particular to an LED integrated lamp panel array distribution design method and device and a storage medium. BACKGROUND

[0002] In order to improve the light-emitting efficiency, the LED integrated lamp panel will arrange the LEDs as closely as possible. However, too small gap between the LEDs will cause two problems, which makes the LED integrated lamp panel unable to work stably. 1. Heat dissipation problem. If the LEDs are arranged too closely, the heat-emitting efficiency during work exceeds the maximum heat dissipation efficiency of the bottom plate, which will form obvious heat island effect and cause the LED lamp to work at low efficiency or even be burned out. 2. Breakdown voltage. In order to make the LED work stably, the LEDs are usually connected in a reasonable S-circuit series-parallel mode, which will form a too high voltage difference at one end. When the voltage difference is higher than the breakdown voltage of the insulating layer outside the LED, the circuit will be short-circuited and unable to work normally.

[0003] In the existing design of the LED integrated lamp panel, the designer can only determine the gap between the LEDs by experience or trial-and-error method. This method is not only low in efficiency, but also difficult to ensure that the designed LED integrated lamp panel has the optimal light-emitting efficiency and stability. In addition, the traditional LED integrated lamp panel design method often ignores the restriction of heat dissipation and breakdown voltage on the gap between the LEDs, which leads to the problems of heat island effect and circuit short circuit in the actual application of the designed LED integrated lamp panel.

[0064] It should be understood that the specific embodiments described herein are merely exemplary of the application and do not limit the application.

[0065] In order to better understand the technical solutions of the present application, the following will be described in detail in combination with the drawings of the specification and specific embodiments.

[0066] The main solution of the embodiment of the present application is: obtaining a target working power of an LED integrated lamp panel, determining a total number of LED lamps based on the target working power; determining a target LED array scheme based on the total number of LED lamps, wherein the target LED array scheme includes the number of LED lamp rows and the number of LED lamp columns; obtaining a minimum gap limited by heat dissipation efficiency and a minimum gap limited by breakdown voltage of the LED integrated lamp panel; determining the horizontal gap and the vertical gap of the LED array according to the minimum gap limited by heat dissipation efficiency and the minimum gap limited by breakdown voltage; determining the overall structure parameters of the LED integrated lamp panel according to the horizontal gap, the vertical gap and the target LED array scheme; and arranging the LED integrated lamp panel array according to the horizontal gap, the vertical gap and the overall structure parameters of the LED integrated lamp panel.

[0067] In the existing design of LED integrated lamp panel, the designer often only relies on experience or trial-and-error method to determine the gap between LEDs, which not only has low efficiency, but also is difficult to guarantee that the designed LED integrated lamp panel has optimal luminous efficiency and stability. In addition, the traditional design method of LED integrated lamp panel often ignores the limitation of heat dissipation and breakdown voltage on the gap between LEDs, which leads to the problems of heat island effect and circuit short circuit in the actual application of the designed LED integrated lamp panel.

[0068] The present application provides a solution, which effectively improves the luminous efficiency by combining the limitation of heat dissipation and breakdown voltage for the gap design between LEDs, and guarantees the working stability of the LED integrated lamp panel.

[0069] It should be noted that the execution subject of the embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, an LED integrated lamp panel array distribution design device, etc. The following will take the LED integrated lamp panel array distribution design device as an example to describe the embodiment and the following embodiments.

[0070] Based on this, the embodiment of the present application provides an LED integrated lamp panel array distribution design method, which refers to Figure 1 , Figure 1A flowchart of a first embodiment of a method for designing an array distribution of an LED integrated lamp panel.

[0071] In this embodiment, the method for designing an array distribution of an LED integrated lamp panel comprises steps S10-S60.

[0072] Step S10: Obtain a target working power of the LED integrated lamp panel, and determine a total number of LED lamps based on the target working power.

[0073] It should be noted that the LED integrated lamp panel is a lighting assembly composed of a plurality of LED lamps arranged in an array form, and the light emitting efficiency and stability thereof directly affect the lighting effect and service life. The target working power of the LED integrated lamp panel is designed in advance, i.e., the expected light emitting power.

[0074] It can be understood that if the working power of the LED integrated lamp panel is W watts, and the working power of a single LED lamp is w watts, then the total number (N) of LED lamps is:

[0075]

[0076] wherein N is the total number of LED lamps, W is the working power of the LED integrated lamp panel, and w is the working power of a single LED lamp.

[0077] Step S20: Determine a target LED array scheme based on the total number of LED lamps, wherein the target LED array scheme comprises a number of rows of LED lamps and a number of columns of LED lamps.

[0078] It should be noted that the LED integrated lamp panel arranges LED lamps in a matrix form, and the number of rows and the number of columns of the matrix directly determine the distribution density and the lighting effect of the LED lamps. After determining the total number of LED lamps, a reasonable LED array scheme needs to be designed, i.e., the number of rows and the number of columns of LED lamps need to be determined, so as to achieve the expected lighting effect.

[0079] It can be understood that the target LED array scheme, i.e., the optimal LED array scheme, can be obtained through various algorithms and design methods. Different LED array schemes can be simulated and tested, and the optimal scheme can be selected to meet the requirements of light emitting efficiency and stability. The grey wolf optimization algorithm can also be used to optimize the initial LED array scheme to obtain the optimal combination of the number of rows of LED lamps and the number of columns of LED lamps, i.e., the optimal LED array scheme. This embodiment does not make specific limitations thereto.

[0080] In an implementation, the step S20 can include: determining a plurality of initial LED array schemes according to the total number of LED lamps, wherein each initial LED array scheme corresponds to a combination of different LED lamp row number and LED lamp column number, and the ratio of the LED lamp row number and the LED lamp column number of each combination is less than or equal to a preset value; optimizing each initial LED array scheme based on a grey wolf optimization algorithm to obtain an optimal LED array scheme; and taking the optimal LED array scheme as the target LED array scheme.

[0081] It should be noted that when the ratio of the LED lamp row number and the column number is different, the LED array presents different shapes and brings different lighting effects. The relationship between the LED lamp row number, the column number and the total number of LED lamps is:

[0082]

[0083] wherein N is the total number of LED lamps, a is the LED lamp row number, and b is the LED lamp column number.

[0084] It can be understood that the product of the LED lamp row number and the column number is equal to the total number of LED lamps. In the preliminary design stage, a ratio range can be preset, which limits the proportional relationship between the LED lamp row number and the column number, so as to ensure the uniformity of the LED array and the balance of the lighting effect. By generating a plurality of initial LED array schemes, that is, a plurality of different combinations of LED lamp row number and LED lamp column number, the optimal LED array scheme can be further screened out. In the embodiment, the combination of the LED lamp row number and the LED lamp column number is less than or equal to a preset value, which can be 30. The embodiment is not limited specifically initially, and the embodiment is described by taking 30 as an example, that is, the LED lamp row number a and the LED lamp column number b satisfy:

[0085]

[0086] It should be noted that after obtaining a plurality of initial LED array schemes, each initial scheme is further optimized based on the grey wolf optimization algorithm. The grey wolf optimization algorithm is an intelligent optimization algorithm that simulates the hunting behavior of a grey wolf group, and has the advantages of fast convergence speed and strong global search ability. Through the algorithm, the optimal LED array scheme can be quickly found from the plurality of initial schemes, that is, the optimal combination of the LED lamp row number and the LED lamp column number is determined.

[0087] In a specific implementation, the optimization of each initial LED array scheme by the grey wolf optimization algorithm mainly includes the following steps: first, initialize the grey wolf population, that is, randomly generate a set of solutions, each solution corresponding to an initial LED array scheme; then, calculate the fitness value of each solution according to the objective function (such as luminous efficiency and stability index) to determine the leader (optimal solution), follower (suboptimal solution) and prey (solution to be optimized) in the grey wolf population; then, simulate the hunting behavior of the grey wolf population, update the position of the grey wolf population, that is, adjust the combination of the number of LED lamp rows and the number of LED lamp columns to approach the optimal solution; repeat the above steps until the preset number of iterations or the fitness value converges, and finally obtain the optimal LED array scheme.

[0088] In a feasible implementation, the optimization of each initial LED array scheme based on the grey wolf optimization algorithm to obtain the optimal LED array scheme includes: initializing the grey wolf population, wherein each grey wolf individual in the grey wolf population represents an initial LED array scheme, and the position of the grey wolf individual is determined by the combination of the number of LED lamp rows and the number of LED lamp columns; calculating the fitness value of each grey wolf individual in the grey wolf population, wherein the fitness value is determined according to the energy efficiency and light uniformity of the LED array; sorting the grey wolf population according to the fitness value, selecting the grey wolf individual with the highest fitness value as the leader, the grey wolf individual with the second highest fitness value as the second leader, and the grey wolf individual with the fitness value in the last preset proportion as the prey; updating the positions of the other grey wolf individuals in the grey wolf population except the leader, the second leader and the prey to obtain the updated grey wolf population, wherein updating the position of the grey wolf individual includes: moving the grey wolf individual towards the leader and the second leader, and adjusting the moving speed and direction of the grey wolf individual according to the position information of the leader and the second leader to gradually approach the optimal solution; recalculating the fitness value of the updated grey wolf population, and sorting and selecting the grey wolf population according to the new fitness value; repeating the process of updating the grey wolf population and recalculating the fitness value until the preset number of iterations is reached or the optimal solution in the grey wolf population converges; selecting the LED array scheme represented by the grey wolf individual with the highest fitness value in the final iteration as the optimal LED array scheme.

[0089] It should be noted that when initializing the grey wolf population, the population size can be set according to the complexity of the actual problem and the limitation of computing resources. If the population size is too large, the calculation amount will increase and the optimization time will be prolonged; if the population size is too small, the global search ability will be reduced and the local optimal solution will be trapped. Therefore, selecting an appropriate population size is crucial to the performance of the grey wolf optimization algorithm.

[0090] It can be understood that after the gray wolf population is initialized, the fitness value of each gray wolf individual needs to be calculated. In the embodiment, the fitness value is determined according to the energy efficiency and illumination uniformity of the LED array. The energy efficiency reflects the luminous efficiency of the LED integrated lamp panel and is an important indicator for evaluating its performance; the illumination uniformity determines the comfort and consistency of the lighting effect. By comprehensively considering these two factors, the pros and cons of the LED array scheme can be comprehensively evaluated. The calculation formula of the fitness value is:

[0091]

[0092] wherein, is the fitness value of the i-th gray wolf individual, represents the energy efficiency of the array, which is usually the ratio of power consumption to light output, represents the uniformity of the illumination, which can be calculated as the variance or standard deviation of the illumination intensity, and are used to control the shape of the function for nonlinear activation of the energy efficiency and the threshold value of the energy efficiency value, and are used to control the shape of the function for nonlinear activation of the illumination uniformity and the threshold value of the uniformity, is the position of the i-th individual in the gray wolf population, represented by the number of rows and columns of the LED array, is the position of the current optimal solution, , , , , , are the weights of each term, respectively, controlling the contribution proportion of each term in the fitness value.

[0093] After obtaining the fitness value of each gray wolf individual, the gray wolf population is sorted, the gray wolf individual with the highest fitness value is selected as the leader, the gray wolf individual with the second highest fitness value is selected as the second leader, and the gray wolf individual with the fitness value in the last preset proportion is selected as the prey. The leader and the second leader represent the optimal solution and the suboptimal solution in the current population,

[0094] which will guide other gray wolf individuals to move in a better direction. The prey represents a poor solution in the current population and needs to be eliminated by other gray wolf individuals. Through such sorting and selection, the diversity and optimization direction of the gray wolf population can be maintained, and falling into a local optimal solution can be avoided.

[0095] In the process of updating the gray wolf population, in addition to the alpha, beta and prey, the positions of other gray wolf individuals will be updated according to the position information of the alpha and beta. Specifically, these gray wolf individuals will move towards the direction of the alpha and beta, and adjust their moving speed and direction according to their position information. Through such a moving strategy, the gray wolf population can gradually approach the optimal solution, improving the performance of the LED array scheme.

[0096] The process of updating the gray wolf population and recalculating the fitness value is repeated until a preset number of iterations is reached or the optimal solution in the gray wolf population converges. In the iteration process, the updated gray wolf population each time will be closer to the optimal solution until the optimal LED array scheme is finally found.

[0097] After selecting the LED array scheme represented by the gray wolf individual with the highest fitness value in the final iteration as the optimal LED array scheme, the scheme will be applied to the design of the LED integrated lamp panel. Through such a design method, the LED integrated lamp panel can have the optimal luminous efficiency and stability to meet the needs of practical applications.

[0098] Step S30: Obtain the minimum gap limited by the heat dissipation efficiency and the minimum gap limited by the breakdown voltage of the LED integrated lamp panel.

[0099] It should be noted that the minimum gap limited by the heat dissipation efficiency refers to the minimum distance between the LED lamps set to ensure that the LED integrated lamp panel can effectively dissipate heat during operation, avoiding the formation of heat island effect due to the heat dissipation efficiency exceeding the maximum heat dissipation efficiency of the bottom plate during operation, which leads to the LED lamp unable to work efficiently and even burn out. This distance is calculated based on the theory of heat conduction and heat convection to ensure that the heat generated by the LED lamp during operation can be dissipated in time to maintain the normal working temperature of the LED integrated lamp panel. At the same time, the minimum gap limited by the breakdown voltage refers to the minimum safe distance between the LED lamps set to prevent the breakdown phenomenon between the LED lamps due to high voltage. This distance is determined according to the breakdown voltage characteristics of the LED lamp and the circuit design requirements to ensure that the LED integrated lamp panel can still work stably under high voltage environment, avoiding circuit short circuit and damage. When designing the LED integrated lamp panel, the limitations of heat dissipation efficiency and breakdown voltage need to be considered comprehensively to determine a reasonable gap between the LED lamps, so as to ensure the working stability and safety of the LED integrated lamp panel while ensuring the luminous efficiency.

[0100] In an implementable embodiment, the step S30 of "obtaining the minimum gap limited by the heat dissipation efficiency of the LED integrated lamp panel" can include: obtaining the unit heat transfer area, the thermal conductivity, the thickness of the bottom plate, the temperature difference of the bottom plate, and the heat generation of the single LED lamp of the LED integrated lamp panel; determining the substrate thermal resistance of the LED lamp according to the unit heat transfer area, the thermal conductivity, and the thickness of the bottom plate; determining the unit heat transfer amount according to the substrate thermal resistance and the temperature difference of the bottom plate; and determining the minimum gap limited by the heat dissipation efficiency of the LED integrated lamp panel according to the unit heat transfer amount and the heat generation of the single LED lamp.

[0101] It should be noted that if the heat generation efficiency of the LED during operation exceeds the maximum heat dissipation efficiency of the bottom plate, a significant heat island effect will be formed, which will cause the LED lamp to be unable to work efficiently and even be burned out. Therefore, when the heat generation efficiency of the LED during operation is less than or equal to the maximum heat dissipation efficiency of the bottom plate, the damage of the LED lamp caused by overheating can be prevented, and then the gap range between the LED lamps is determined according to the relationship between the two, and then the minimum gap limited by the heat dissipation efficiency is determined.

[0102] It can be understood that when determining the minimum gap limited by the heat dissipation efficiency, factors such as the unit heat transfer area, the thermal conductivity, the thickness of the bottom plate, the temperature difference of the bottom plate, and the heat generation of the single LED lamp of the LED integrated lamp panel need to be considered comprehensively. Through accurate calculation and analysis, the minimum safe distance between the LED lamps, i.e., the minimum gap limited by the heat dissipation efficiency, can be obtained under the premise of ensuring the effective heat dissipation of the LED integrated lamp panel. The setting of this gap is crucial for the long-term stable operation of the LED integrated lamp panel, and can effectively avoid the damage and efficiency reduction of the LED lamp caused by overheating.

[0103] It should be noted that because the LED bottom plate is an isotropic medium, its thermal conductivity in each direction is the same. Therefore, the unit area is set as the area away from the short edge of the LED by the minimum gap limited by the heat dissipation efficiency , i.e., the coverage area, which is the unit heat transfer area . The calculation formula of the unit heat transfer area is as follows:

[0104]

[0105] wherein, is the unit heat transfer area of the LED integrated lamp panel, is the length of the single LED lamp, is the height of the single LED lamp, is the minimum gap limited by the heat dissipation efficiency.

[0106] In the working state of the LED lamp, the heat generated by the LED lamp and the heat dissipated by the unit area of the substrate reach a stable state, and in this state, the LED lamp and the unit area of the substrate can be regarded as a whole to transfer heat to the heat-conducting sheet with higher thermal conductivity. At this time, the heat generated by a single LED lamp is:

[0107]

[0108] wherein, is the heat generated by a single LED lamp, I is the current, and R is the resistance.

[0109] The substrate thermal resistance (Rth) of the LED lamp is:

[0110]

[0111] wherein, is the substrate thermal resistance of the LED lamp, d is the thickness of the substrate, is the thermal conductivity, is the unit heat transfer area of the LED integrated lamp plate.

[0112] Therefore, the heat transfer per unit area is:

[0113]

[0114] wherein, is the unit heat transfer, is the temperature difference between the upper and lower surfaces of the substrate, and is related to the overall heat dissipation structure, is the substrate thermal resistance of the LED lamp.

[0115] It is worth noting that in the case of stable operation of the LED without continuous accumulation of heat, the heat generated by the LED needs to be less than or equal to the heat dissipated per unit area, that is:

[0116]

[0117] That is:

[0118]

[0119]

[0120] The minimum gap that limits the heat dissipation efficiency can be determined by the above formula. .

[0121] ​In an implementable embodiment, the step S30 of "obtaining the breakdown voltage limit minimum gap of the LED integrated lamp panel" can include: obtaining a voltage difference and a breakdown distance of a target breakdown region, wherein the target breakdown region is a region corresponding to two LED lamps with the largest ratio of the voltage difference to the breakdown distance; determining a breakdown voltage according to the breakdown distance and the dielectric strength of the insulator; and determining the breakdown voltage limit minimum gap according to the breakdown voltage and the voltage difference.

[0122] It should be noted that in the present embodiment, the LEDs are also connected in series-parallel S-circuit mode to ensure the stability and safety of the circuit, and the heat dissipation structure enables the airflow to flow in the heat dissipation fins to improve the heat dissipation efficiency. The breakdown voltage limit minimum gap is set to prevent the breakdown phenomenon between the LED lamps due to excessively high voltage in a high-voltage environment, resulting in circuit short circuit and damage. Therefore, when obtaining the breakdown voltage limit minimum gap, factors such as the voltage difference of the target breakdown region, the breakdown distance, and the dielectric strength of the insulator need to be considered comprehensively. Through accurate calculation and analysis, the minimum safe distance between the LED lamps, i.e., the breakdown voltage limit minimum gap, can be obtained under the premise of ensuring the safety of the circuit. The setting of this gap is crucial for the stable operation of the LED integrated lamp panel in a high-voltage environment, and can effectively avoid circuit failure and damage caused by breakdown.

[0123] It can be understood that the target breakdown region is the region that is most easily broken down by voltage, and the ratio of the voltage difference to the breakdown distance of this region is the largest, and the breakdown distance is the distance between the corresponding two LED lamps. Figure 2 As shown in Figure 2 , the circuit schematic diagram of the LED integrated lamp panel is shown, and the LEDs are connected in series-parallel S-circuit mode in the LED integrated lamp panel. The region between A and B in the figure is the region that is most easily broken down by voltage, and A and B are the LEDs with the largest ratio of the voltage difference to the breakdown distance. The breakdown distance is the distance between A and B.

[0124] The voltage difference of the region that is most easily broken down by voltage is :

[0125]

[0126] wherein, is the voltage difference, a is the number of LED lamp rows, is the working voltage of a single LED.

[0127] The breakdown distance ( ) is:

[0128]

[0129] wherein, is the breakdown distance, is the height of a single LED lamp, is the breakdown voltage limit minimum gap.

[0130] Since the breakdown voltage of the insulator satisfies:

[0131] wherein, is the breakdown voltage of the insulator, is the dielectric strength of the insulator, is the breakdown distance.

[0132] Therefore, in order to make the LED work stably, i.e. the medium is not broken down, it is required to satisfy that the breakdown voltage is greater than or equal to the voltage difference at that place:

[0133]

[0134] That is:

[0135]

[0136] Therefore, the breakdown voltage limit minimum gap is:

[0137]

[0138] It should be noted that after the heat dissipation efficiency limit minimum gap and the breakdown voltage limit minimum gap are determined, the reasonable gap range between the LED lamps can be determined according to the limit conditions of the two gaps and the design requirements of the LED integrated lamp panel. The setting of this gap range needs to ensure the light emitting efficiency while ensuring the working stability and safety of the LED integrated lamp panel. Through reasonable gap setting, the performance of the LED integrated lamp panel can be optimized, and its light emitting efficiency and stability can be improved.

[0139] Step S40: determining the horizontal gap and the vertical gap of the LED array according to the heat dissipation efficiency limit minimum gap and the breakdown voltage limit minimum gap.

[0140] It should be noted that the breakdown voltage factor limits the minimum gap in the vertical direction, and the heat dissipation factor affects the minimum gap in the left-right direction and the up-down direction, so the specific size relationship between the heat dissipation efficiency limit minimum gap and the breakdown voltage limit minimum gap is required to determine the minimum gap in the horizontal direction and the vertical direction.

[0141] In an implementable embodiment, step S40 can include: comparing the heat dissipation efficiency limit minimum gap and the breakdown voltage limit minimum gap to obtain a comparison result; in the case that the comparison result is that the heat dissipation efficiency limit minimum gap is less than the breakdown voltage limit minimum gap, taking the heat dissipation efficiency limit minimum gap as the horizontal gap of the LED array and taking the breakdown voltage limit minimum gap as the vertical gap of the LED array; in the case that the comparison result is that the heat dissipation efficiency limit minimum gap is greater than the breakdown voltage limit minimum gap, taking the heat dissipation efficiency limit minimum gap as the horizontal gap and the vertical gap of the LED array.

[0142] It should be noted that in the case that the heat dissipation efficiency limit minimum gap is less than the breakdown voltage limit minimum gap, that is, at this time, the heat dissipation factor becomes the dominant factor in determining the gap size of the LED array. Since heat dissipation mainly affects the horizontal direction (left and right) and the vertical direction (up and down) of the LED lamp spacing, the heat dissipation efficiency limit minimum gap is selected as the horizontal gap of the LED array, that is, the minimum gap in the horizontal direction, which can ensure that the LED lamp will not be poorly cooled due to too small spacing in the horizontal direction. At the same time, the breakdown voltage limit minimum gap is selected as the vertical gap of the LED array, that is, the minimum gap in the vertical direction, which can ensure that even if there is a high voltage difference in the vertical direction, breakdown will not occur due to too small gap, ensuring the safety of the circuit.

[0143] It can be understood that in the case that the heat dissipation efficiency limit minimum gap is greater than the breakdown voltage limit minimum gap, that is, at this time, the heat dissipation factor and the breakdown voltage factor jointly affect the setting of the gap size of the LED array. Since the heat dissipation efficiency limit minimum gap is greater than the breakdown voltage limit minimum gap in numerical value, it means that when setting the gap of the LED array, both the heat dissipation and the breakdown voltage factors need to be considered to ensure the working stability and safety of the LED integrated lamp panel. Therefore, in this case, the heat dissipation efficiency limit minimum gap can be selected as the horizontal gap and the vertical gap of the LED array, that is, the minimum gap in the horizontal direction and the vertical direction is set to . Such a setting can ensure effective heat dissipation of the LED lamp while also ensuring that breakdown will not occur due to too high voltage difference in the vertical direction, thereby comprehensively improving the performance and stability of the LED integrated lamp panel. Through reasonable gap setting, the luminous efficiency and stability of the LED integrated lamp panel can be further optimized to meet the needs of various application scenarios.

[0144] Step S50: determining the overall structure parameters of the LED integrated lamp panel according to the horizontal gap, the vertical gap and the target LED array scheme.

[0145] It should be noted that the overall structure parameters of the LED integrated lamp panel include the minimum coverage area length and height of the LED array.

[0146] It can be understood that after the horizontal gap and the vertical gap are determined, the minimum coverage area of the LED integrated lamp panel can be determined according to the gap values in combination with the target LED array scheme, i.e., the number of rows and columns of the LED lamp. The length and height of the minimum coverage area will directly affect the size and shape of the LED integrated lamp panel. At the same time, according to these structure parameters, the specific arrangement mode between the LED lamps, including the distance and angle between the lamps, can be further refined to ensure that the light emitting effect and heat dissipation performance of the entire LED integrated lamp panel reach the best state.

[0147] Step S60: arranging the LED integrated lamp panel array according to the horizontal gap, the vertical gap and the overall structure parameters of the LED integrated lamp panel.

[0148] It should be noted that after the horizontal gap, the vertical gap and the overall structure parameters of the LED integrated lamp panel are determined, the array layout design of the LED integrated lamp panel can be performed according to the two gap values. When laying out, the distance between each LED lamp and its adjacent lamp should meet the minimum gap requirement determined, and the minimum coverage area of the LED array should also be met to ensure the light emitting uniformity and heat dissipation efficiency of the entire LED integrated lamp panel.

[0149] It can be understood that during the layout process, the connection mode and circuit layout between the LED lamps also need to be considered to ensure the stability and safety of the circuit. Through reasonable array arrangement, the LED integrated lamp panel can reach the best state in terms of light emitting efficiency, heat dissipation performance and stability to meet the needs of various application scenarios. At the same time, the rationality of the array arrangement will directly affect the manufacturing cost and production efficiency of the LED integrated lamp panel, so during the array arrangement, multiple factors need to be considered to ensure that the finally designed LED integrated lamp panel has excellent performance and cost-effectiveness. During the arrangement process, advanced layout software and algorithms can be used to simulate and optimize the arrangement mode of the LED lamps to achieve the best light emitting effect and heat dissipation performance. For example, intelligent layout algorithms can be used to automatically calculate and adjust the positions and distances of the LED lamps to ensure that the minimum gap requirement is met while optimizing the light emitting effect and heat dissipation performance. During the simulation process, the light emitting characteristics, heat dissipation requirements and circuit layout of the LED lamps can be fully considered, and the arrangement mode of the LED lamps can be continuously adjusted and optimized to make the light emitting uniformity, heat dissipation efficiency and circuit stability of the entire LED integrated lamp panel reach the best state.

[0150] The embodiment provides a LED integrated lamp panel array distribution design method, acquires target working power of a LED integrated lamp panel, determines total quantity of LED lamps based on the target working power; determines a target LED array scheme based on the total quantity of LED lamps, wherein the target LED array scheme comprises quantity of LED lamp rows and quantity of LED lamp columns; acquires a heat dissipation efficiency limit minimum gap and a breakdown voltage limit minimum gap of the LED integrated lamp panel; determines horizontal and vertical gaps of an LED array according to the heat dissipation efficiency limit minimum gap and the breakdown voltage limit minimum gap; determines overall structure parameters of the LED integrated lamp panel according to the horizontal and vertical gaps and the target LED array scheme; and arranges the LED integrated lamp panel array according to the horizontal and vertical gaps and the overall structure parameters of the LED integrated lamp panel. In the foregoing manner, the gaps between LEDs are designed by combining the heat dissipation and breakdown voltage limits, the luminous efficiency is effectively improved, and meanwhile, the working stability of the LED integrated lamp panel is ensured.

[0151] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as the above-mentioned first embodiment can be referred to the above introduction, and the subsequent will not be described in detail. On this basis, please refer to Figure 3 , step S50 comprises steps S501-S504:

[0152] Step S501: determining the quantity of LED lamp rows and the quantity of LED lamp columns according to the target LED array scheme.

[0153] It should be noted that after the target LED array scheme is determined, the quantity of rows a and the quantity of columns b of the required LED lamps are clear, and different quantity of rows and columns will directly affect the light emitting effect and heat dissipation performance of the LED integrated lamp panel.

[0154] It can be understood that after the quantity of rows a and the quantity of columns b are determined, the specific arrangement mode between the LED lamps can be further refined, including the distance, angle and the like between the lamps, so as to further determine the overall structure parameters of the LED integrated lamp panel.

[0155] Step S502: acquiring the length and height of a single LED.

[0156] It should be noted that after the length l and the height h of a single LED are acquired, these parameters will be used to calculate the minimum coverage area of the LED integrated lamp panel. Length lGenerally refers to the size of the LED lamp in the horizontal direction, while the height h refers to the size of the LED lamp in the vertical direction. Understanding the size information of a single LED is crucial for determining the layout of the entire LED integrated lamp panel, as it will directly affect the distance between the lamps, the compactness of the array, and the final lighting effect.

[0157] Step S503: Determine the LED array minimum coverage area length and the LED array minimum coverage area height according to the horizontal gap, the vertical gap, the number of LED lamp rows, the number of LED lamp columns, and the length and height of a single LED.

[0158] It should be noted that the calculation method of the LED array minimum coverage area length ensures that the LED lamps will not be poorly cooled due to too small a gap in the horizontal direction, while also ensuring the compactness of the layout and the lighting effect of the LED integrated lamp panel in the horizontal direction. The calculation of the LED array minimum coverage area height ensures that the LED lamps will not be subjected to breakdown due to too small a gap in the vertical direction, while also ensuring the rationality of the layout and the safety of the circuit of the LED integrated lamp panel in the vertical direction.

[0159] It can be understood that the LED array minimum coverage area length is determined according to the number of LED lamp rows, the length of a single LED, and the minimum gap limited by the heat dissipation efficiency, while the LED array minimum coverage area height is determined according to the number of LED lamp columns, the height of a single LED, and the specific size relationship of the minimum gap limited by the heat dissipation efficiency and the minimum gap limited by the breakdown voltage .

[0160] In a feasible implementation, step S503 can include steps A11-A12:

[0161] Step A11: When the horizontal gap is the minimum gap limited by the heat dissipation efficiency and the vertical gap is the minimum gap limited by the breakdown voltage, determine the LED array minimum coverage area length according to the number of LED lamp rows, the length of a single LED, and the minimum gap limited by the heat dissipation efficiency, and determine the LED array minimum coverage area height according to the number of LED lamp rows, the number of LED lamp columns, the height of a single LED, and the minimum gap limited by the breakdown voltage.

[0162] It should be noted that in this embodiment, the horizontal gap is the minimum gap limited by the heat dissipation efficiency and the vertical gap is the minimum gap limited by the breakdown voltage , that is , the minimum gap in the horizontal direction is , and the minimum gap in the vertical direction is .

[0163] LED array minimum coverage area length (L):

[0164] wherein, a is the number of LED lamp rows, is the length of a single LED, is the heat dissipation efficiency limited minimum gap.

[0165] The formula ensures that the minimum gap between adjacent LED lamps when the LED lamps are arranged in the horizontal direction is the heat dissipation efficiency limited minimum gap , thereby ensuring the heat dissipation performance and light emitting effect of the LED integrated lamp panel in the horizontal direction. At the same time, considering the length of the LED lamp itself, by accumulating the length of each row of LED lamps and the gap therebetween, the minimum coverage length of the entire LED array in the horizontal direction can be obtained.

[0166] LED array minimum coverage area height (H):

[0167]

[0168] wherein, b is the number of LED lamp columns, h is the height of a single LED, is the breakdown voltage limited minimum gap.

[0169] The formula ensures that the minimum gap between adjacent LED lamps when the LED lamps are arranged in the vertical direction is the breakdown voltage limited minimum gap , thereby ensuring the circuit safety and light emitting effect of the LED integrated lamp panel in the vertical direction. Similarly, considering the height of the LED lamp itself, by accumulating the height of each column of LED lamps and the gap therebetween, the minimum coverage height of the entire LED array in the vertical direction can be obtained.

[0170] Step A12: when the horizontal gap and the vertical gap are both heat dissipation efficiency limited minimum gaps, determining the LED array minimum coverage area length according to the number of LED lamp rows, the length of a single LED, and the heat dissipation efficiency limited minimum gap, and determining the LED array minimum coverage area height according to the number of LED lamp rows, the number of LED lamp columns, the height of a single LED, and the heat dissipation efficiency limited minimum gap.

[0171] It should be noted that in the present embodiment, the horizontal gap and the vertical gap are both heat dissipation efficiency limited minimum gaps , that is, , the horizontal direction minimum gap is , and the vertical direction minimum gap is .

[0172] LED array minimum coverage area length (L):

[0173] wherein, a is the number of LED lamp rows, is the length of a single LED, is the minimum gap limited by heat dissipation efficiency.

[0174] The minimum coverage area length of the LED array (H) is:

[0175]

[0176] wherein, b is the number of LED lamp columns, h is the height of a single LED, is the minimum gap limited by heat dissipation efficiency.

[0177] This formula ensures that the minimum gap between adjacent LED lamps in both horizontal and vertical directions is the minimum gap limited by heat dissipation efficiency , which is suitable for scenarios where the minimum gap limited by heat dissipation efficiency is greater than the minimum gap limited by breakdown voltage. By uniformizing the gap size in both horizontal and vertical directions, the overall size of the LED integrated lamp panel can be minimized while ensuring heat dissipation performance and improving layout compactness.

[0178] It is worth noting that when determining the minimum coverage area length and height, the size and number of LED lamps themselves must be considered to ensure the lighting effect and circuit safety of the entire LED array.

[0179] Step S504: Take the minimum coverage area length of the LED array and the minimum coverage area height of the LED array as the overall structure parameters of the LED integrated lamp panel.

[0180] It should be noted that the minimum coverage area length and height of the LED array are key components of the overall structure parameters of the LED integrated lamp panel, which directly determine the size and layout of the LED integrated lamp panel. By taking these two parameters as part of the overall structure parameters, the LED integrated lamp panel can meet the heat dissipation and breakdown voltage limitations while achieving the best lighting effect and circuit layout.

[0181] It can be understood that after determining the overall structure parameters of the LED integrated lamp panel, the array arrangement of the LED integrated lamp panel can be further performed. According to the determined horizontal gap, vertical gap, and the number of LED lamp rows and columns, the LED lamps are arranged on the LED integrated lamp panel in the predetermined arrangement manner. This arrangement not only ensures the reasonable spacing between LED lamps, but also ensures the uniformity of the entire LED integrated lamp panel and the heat dissipation performance. Finally, by comprehensively considering the heat dissipation efficiency, breakdown voltage limitation, and the specific size and number of LED lamps, an efficient, stable, and compactly laid out LED integrated lamp panel array distribution scheme is designed.

[0182] In the embodiment, the specific size relationship of the minimum gap limited by the heat dissipation efficiency and the minimum gap limited by the breakdown voltage and the number of rows and the number of columns of the LED lamp are considered to determine the overall structure parameters of the LED integrated lamp panel, which not only ensures the reasonable spacing of the LED lamp in the horizontal and vertical directions, but also takes into account the heat dissipation performance and circuit safety, so as to realize the efficient, stable and compact layout of the LED integrated lamp panel.
