Detailed Description
The principles and features of the present invention are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the invention and are not to be construed as limiting the scope of the invention.
As shown in fig. 1, a flow chart of an LED lamp array wiring method based on a network analysis method according to an embodiment of the present invention is shown, where the method includes:

It should be noted that, the network analysis method (Analytic Network Process, ANP) is a decision method adapting to a non-independent hierarchical structure proposed by the university of pittsburgh, usa, teaching in 1996, and is a new practical decision method formed by developing on the basis of the hierarchical analysis method ((Analytic Hierarchy Process, AHP), and because the network structure model is far more complex than the hierarchical structure model, the network analysis method is applied to deeper mathematical knowledge in terms of weight synthesis, wherein the more important concept is the application and analysis of the super matrix, the representation of the network model and the synthesis of the weight are the most important two aspects in the network analysis method.
Specifically, in S150, the network analysis model includes a control layer and a network layer, where a total target of the control layer is a comprehensive evaluation of LED array coordinates; the decision criteria of the control layer are illuminance uniformity, heat dissipation effect, illumination intensity and lowest total cost; the network layer is composed of the second element set; the elements in the second element set are generated by one or more of illumination uniformity, heat dissipation effect, illumination intensity and minimum total cost of the LED arrays corresponding to each group of LED array coordinates; the network analysis model is expressed as a total objective function:
Z＝maxf(X)＝αZ 1 +βZ 2 +λZ 3 +θZ 4
wherein Z is the comprehensive evaluation value of the LED array coordinates, Z 1 For uniformity of illuminance, Z 2 Z is the heat dissipation effect 3 For the illumination intensity, Z 4 For the lowest total cost, α, β, γ, θ are weights of illuminance uniformity, heat radiation effect, illumination intensity, and the lowest total cost, and α+β+γ+θ=1, respectively.
It should be noted that, the network analysis model is established by calculating the weight proportion of the illuminance uniformity, the heat dissipation effect, the illumination intensity and the lowest total cost of the LED array in the total objective function Z of the network analysis model, so as to optimize the LED array to select the optimal LED array coordinate.
Specifically, as shown in fig. 2, step S110 in fig. 1 specifically further includes the following steps:
111, determining a lamp structure, illumination intensity, an illumination area and an energy saving level according to the use requirements and the use places of users;
112, selecting the types of the LED lamps and the number of the LED lamps according to the lamp structure, the intensity requirement, the illumination area and the energy-saving level.
It should be noted that, according to the LED lamp array wiring method provided by the invention, the illumination area is calculated according to the use requirement and the use place proposed by the user, for example, the LED lamp array wiring method is used as a reading lamp, a pendant lamp, a bedside lamp and the like, for example, a range reference of illumination uniformity and illumination intensity is provided for the user aiming at the reading lamp, and meanwhile, the user can select the lamp structure, for example, the structure can be heart-shaped, round-shaped, rectangular-shaped and the like. In addition, on the premise of processing permission, the user has the greatest freedom degree in selecting the lamp structure to select the appearance structure of the lamp.
Specifically, as shown in fig. 3, step S120 in fig. 1 specifically further includes the following steps:
121, calculating the weight of the initial cost and the operation cost by using an analytic hierarchy process;
122, calculating the weight of each first element set by using the first single criterion;
123 calculating the weight of each of the first element sets using a first multi-criterion;
124, optimizing the total cost of the lamp according to the calculated ownership weight to the lowest total cost;
wherein the first set of elements is generated from a combination of one or more elements of design cost, material cost, production cost, installation cost, maintenance cost, power cost, and LED lamp replacement cost; the first single criterion is based on one of initial cost and operation cost; the first plurality of criteria is based on initial cost and operating cost.
It should be noted that the total cost includes an initial cost and an operation cost, and the initial cost includes a design cost, a material cost, a production cost, and an installation cost; the operating costs include maintenance costs, power costs, and LED lamp replacement costs.
Specifically, as shown in fig. 4, step 122 specifically includes:
1221, establishing a super matrix W by using a network analysis method, and comparing the relative importance of design cost, material cost, production cost and installation cost by taking the total cost as a main criterion and the initial cost as a secondary criterion;
1222, establishing a weight matrix alpha model, comparing and judging each first element set by taking the total cost as a main criterion and the operation cost as a secondary criterion, and obtaining a weight matrix alpha by constructing a judging matrix and calculating a characteristic vector thereof;
1223, establishing a weighted hyper-matrix to solve the weight matrix alpha to obtain the weight of the first element set.
It should be noted that, in step 1221, the total cost of the lamp is optimized by using the network analysis method, specifically, an analysis model is built, where the analysis model uses the total cost as a total target, uses initial cost and operation cost as decision criteria of the analysis model, uses design cost, material cost, installation cost of production cost, maintenance cost, electric power cost and replacement cost of the LED lamp as an element set of a network layer of the analysis model, and indirectly compares the dominance of elements in the element set according to the influence of the elements on the decision criteria.
Specifically, the lamps are meshed and divided to obtain a plurality of groups of LED array coordinates, wherein the LED array coordinates are in a first group L1: (X) 11 ，Y 11 ，Z 11 ；X 12 ，Y 12 ，Z 12 ；……；X 1m ,Y 1m ,Z 1m ) Second group L2: (X) 21 ，Y 21 ，Z 21 ；X 22 ，Y 22 ，Z 22 ；……；X 2m ，Y 2m ，Z 2m ) … …, n-th group Ln: (X) n1 ，Y n1 ，Z n1 ；X 22 ，Y n2 ，Z n2 ；……；X nm ，Y nm ，Z nm ),
Wherein n is the number of groups of LED array coordinates, and m is the number of LED lamps in each group of LED arrays.
It should be noted that, the meshing of the selected lamp structure means that a plurality of LED lamps need to be arranged on the lamp, if the selected lamp is circular, the plane in which the LEDs are placed in the lamp is circular, and we need to mesh the circular plane to generate two-dimensional LED coordinates; similarly, if the lamp appearance structure is rectangular, the rectangle is divided. Meanwhile, the LED array also has the space arrangement condition, namely, not all the LED lamps are arranged on one plane, so that the whole space is subjected to gridding division to generate three-dimensional coordinates; in special use cases, the installation angle of the LED lamp can also be added to the meshing division, i.e. the factor of adding the angle of approach to the three-dimensional coordinates. And in principle, the meshing division should be as fine as possible with the convenience of calculation.
Specifically, as shown in fig. 5, step S150 in fig. 1 specifically further includes the following steps:
151, calculating illuminance uniformity of the LED arrays corresponding to each group of LED array coordinates;
152, performing temperature distribution simulation on the LED arrays, and evaluating the heat dissipation effect of each group of LED arrays;
153, calculating the illumination intensity of each group of the LED arrays;
154, analyzing the weight proportion of the second element set in the network layer of the network analysis model to obtain the weight proportion of the illumination uniformity, the heat dissipation effect, the illumination intensity and the minimum total cost of all the LED arrays;
155, calculating a Z value of a total objective function corresponding to the network analysis model according to the weight proportion obtained by analysis, wherein the LED array coordinate corresponding to the maximum Z value is the optimal LED array coordinate.
In step 151, the illuminance uniformity of each set of LED array coordinates is calculated, and first, a point P (x) of a single LED lamp in each set of LED arrays on the irradiation target plane is calculated i ,y j ,z k ) The illuminance at the place is:then m LED lamps in the array are pointed P (x i ,y j ,z k ) The illumination intensity at the place is: />Wherein X in the expression n 、Y n Respectively representing the coordinates of the nth LED in each group of arrays, I LED The illumination intensity of the center of the LED chip is represented, and the illumination intensity and the emission angle satisfy the formula: i=i LED cos t+1 θ, where θ is the emission angle of the light. The illuminance uniformity is then defined as the ratio of the average value of the illuminance at each point on the illumination plane to the maximum illuminance value, i.e +.>Wherein u is illuminance uniformity, ++>For average illuminance, the average illuminance is expressed as: />E max At maximumThe illuminance value can be calculated to obtain the illuminance uniformity in each group of LED arrays.
In step 152, temperature distribution simulation may be performed on the LED array by ANSYS software, so as to evaluate the heat dissipation efficiency of the LED array, and quantify the heat dissipation efficiency as a heat dissipation effect.
Specifically, as shown in fig. 6, 154 specifically further includes the following steps:
1541, the weight of illuminance uniformity, heat dissipation effect, illumination intensity, minimum total cost of the LED array;
1542, calculating the weight proportion of each second element set by using the second single criterion;
1543, calculating the weight ratio of each of said second element sets using a second plurality of criteria.
Wherein the second single criterion is based on one element of the illuminance uniformity, the heat radiation effect, the illumination intensity and the total cost; the second plurality of criteria is based on two or more elements of the illuminance uniformity, the heat dissipation effect, the illumination intensity, and the total cost.
Specifically, step 1542 specifically further includes the steps of:
15421 comparing the relative importance of the LED array coordinates of other groups by taking the illuminance uniformity as a main criterion and the illuminance of any group of LED array coordinates at a preset point P as a secondary criterion;
15422, establishing a weight matrix a model, taking the optimal LED array coordinates as a main criterion, taking the illuminance uniformity, the heat dissipation effect, the illumination intensity and the total cost as secondary criteria, comparing and judging each second element set, constructing a judgment matrix model and calculating the feature vector of the judgment matrix;
15423, establishing a weighted super matrix to solve the judgment matrix model, and obtaining the weight proportion of illumination uniformity, heat dissipation effect, illumination intensity and the lowest total cost in each group of LED array coordinates.
The weight ratio of the illuminance uniformity, the heat dissipation effect, the illumination intensity, and the minimum total cost of the LED array is calculated to optimize the comprehensive evaluation of the illuminance uniformity, the heat dissipation effect, the illumination intensity, and the minimum total cost of the LED array, thereby selecting the optimal LED array coordinate. Because in the LED array, the α, β, γ, θ illuminance uniformity, heat dissipation effect, illumination intensity, weight of the lowest total cost, and α+β+γ+θ=1, four elements of the illuminance uniformity, heat dissipation effect, illumination intensity, and the lowest total cost are analyzed in the LED array at the ratio, and the analysis is to realize: the illuminance uniformity is the most obvious factor when a user uses the LED lamp, and whether the illuminance uniformity directly affects the illumination effect of the LED lamp or not, so that the first consideration factor of LED array optimization is that the illuminance of the lamp is more uniform; the heat dissipation effect is optimal, because the highest junction temperature born by the LEDs in the working process is 120 ℃, the heat dissipation performance becomes one of the key problems in the wiring design of the LED array, and the reasonable arrangement of the distance between the LED lamps in the LED array is an important scheme for optimizing the heat dissipation effect; the illumination intensity reaches the requirement of clients, the illumination intensity is an important characteristic of illumination, and under different use conditions, users can have different experiences by using different illumination intensities.
In addition, in the practical application scene, the invention is not limited to evaluating the illuminance uniformity, the heat dissipation effect, the illumination intensity and the minimum total cost in the LED array, and other factors can be considered according to the practical requirements.
