Description

Technical Field

[0001] The present disclosure relates to the technical field of architectural design, and in particular, to a method and device for arranging room lamps, and a computer-readable storage medium and electronic device. Background Art

[0002] At present, my country's building sector accounts for about 35% of the country's total energy consumption, and carbon emissions account for about 42% of the total carbon emissions. Among them, building lighting energy consumption accounts for 25% to 35% of the total building energy consumption. Therefore, reasonable planning of building lighting design and reduction of building lighting energy consumption can play an important role in energy conservation and emission reduction. At the same time, reasonable building lighting quality can also improve the work efficiency of building users and have a positive effect on their physical and mental health.

[0003] The existing room lighting layout is mostly done manually by electrical designers. Designers obtain room information and then estimate the number of lamps based on experience or lighting power density. However, the estimated results are often different from the actual design requirements. In this case, designers need to check repeatedly, which increases their workload. In addition, due to the pressure of design deadlines, the time given to lighting layout design is mostly tight. Ultimately, the design of lighting layout has flaws and cannot meet the design standards. Summary of the invention

[0072] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application.

[0074] It should be understood that, although the terms first, second, third, etc. may be used in the present application to describe various information, these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "at..." or "when..." or "in response to determination". In the absence of conflict, the features in the following embodiments and implementations may be combined with each other.

[0075] The inventor of the present application found that for regular rooms, such as rectangular rooms, when arranging lamps, the designer needs to spend a lot of time to arrange the positions of the lamps in each room separately, which accounts for a large proportion of the workload of the electrical designer. It is also possible that due to reasons such as construction period, the designer does not have enough time to calculate and determine the lamps for each room. At the same time, due to the different levels of designers, the design quality cannot always be guaranteed.

[0076] Based on the above reasons, a method for arranging lighting facilities in a room, especially a rectangular room, is proposed.

[0077] In the following, a rectangular room is taken as an example to illustrate the method for arranging room lamps according to the present invention. It should be pointed out that the following embodiments are only exemplary embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Based on the following embodiments, those skilled in the art can also derive lamp arrangement methods for rooms of other shapes or arrangement methods for other equipment in a room.

[0078] See also Figures 1 to 9 As shown, a method for arranging lighting facilities in a room includes the following steps:

[0079] like Figure 1 and Fig. 9 As shown, S101: obtaining basic room information from the design file.

[0080] The design file may include, for example, an electronic file, such as a BIM model or a CAD drawing or the like, which includes, for example, information about a regular room, such as a rectangular or square room.

[0081] It can be understood that room not only refers to indoor rooms, but also refers to regular corridors, factories and competition venues, etc.

[0082] The BIM model or CAD drawing is generated according to the design plan of the building to be designed, wherein the BIM model or CAD drawing is a readable electronic model or drawing.

[0083] In the case of a BIM model, basic room information can be automatically queried from the BIM model.

[0084] In the case of CAD drawings, basic room information can be obtained through room graphics and building construction practice tables, and can be obtained manually by a user or automatically, for example.

[0085] It should be noted that the basic information of the room may include but is not limited to the basic information needed to arrange lamps, such as room name and number, length, width, height, floor material, ceiling material, wall material, window material, door material, wall decoration material, wall width, wall height, window width, window height, door width, door height, wall decoration width, wall decoration height and other information.

[0086] In one embodiment, before step S101, a step S100 of preparing a resource database is optionally included, in which information required for arranging lamps, such as lamp information and room building information, is stored. Therefore, specifically, the step of preparing the resource database at least includes: establishing a room building information list and establishing a lamp information list.

[0087] Among them, for the design of lamps, the room building information list should include the reflectance list corresponding to various building materials on the room surface and the room lighting design standard list. The lamp information list includes the lamp information list and the lamp utilization coefficient table.

[0088] In addition, in the step of establishing a room building information list, at least the reflectance ratio relationship of commonly used materials in the room is stored in the resource data, such as the reflectance ratio relationship corresponding to the floor material, ceiling material, wall material, window material, door material, wall decoration material, etc., and a reflectance ratio list of materials is constructed based on the above information, as shown in Table 1. Table 1 only lists some materials and the reflectance ratio (ρ) corresponding to the material as an example.

[0089] Material Name ρ value plaster 0.91 Whitewash 0.75 Cement mortar finishing 0.32 White cement 0.75 White latex paint 0.84

[0090] Table 1 Reflectance list

[0091] In the step of establishing a room lighting design standard list, resource data is prepared, such as a room lighting design standard list, which includes, for example, lighting design standards that are conventional provisions in industry standards, such as the "General Specification for Energy Conservation and Renewable Energy Utilization in Buildings" GB 55015-2021, and user-defined illumination standard values ​​for various types of rooms, lighting power density LPD, reference plane height and maintenance factor, etc., as shown in Table 2, which only exemplarily lists part of the content of the room lighting design standard list.

[0092]

[0093] Table 2 List of room lighting design standards

[0094] In the step of establishing the lamp information list, the lamp information list is also stored in the resource data. The lamp information may include, for example, lamp ID, lamp type, lamp model, light source quantity, light source luminous flux, lamp rated power, lamp legend name, lamp family name, lamp type name, lamp maximum allowable row height ratio, and lamp maximum allowable column height ratio. The lamp information list is organized into a data table that can be queried by the program, as shown in Table 3, which only lists part of the contents of the lamp information table by way of example.

[0095]

[0096]

[0097] Table 3 Lighting information list

[0098] like Figure 2 and Figure 3 As shown, the maximum allowable row spacing height ratio of lamps in Table 3 can be understood as the ratio of the maximum row spacing to the hanging height of the lamp to the work surface when the long axis of the lamp and the row of lamps are consistent.

[0099] The maximum allowable column spacing height ratio of lamps can be understood as: when the long axis of the lamps and the row of lamps are consistent, the ratio of the maximum column spacing to the hanging height of the lamps to the work surface.

[0100] In this step, the resource data also stores a lamp utilization coefficient table corresponding to various room construction conditions, such as different room shape indexes and reflectances of different building materials, etc. In this article, the room shape index is understood as a numerical value representing the geometric shape of a room or place. It should be noted that in the context of this application, the utilization coefficient can be understood as the ratio of the luminous flux received on the working surface (or another specified reference plane) to the rated luminous flux emitted by the light source. The utilization coefficient table including the utilization coefficients of each lamp is organized into a data table for query, as shown in Table 4, which only lists part of the content of the utilization coefficient table by way of example.

[0101]

[0102] Table 4 Utilization coefficient table

[0103] The resource database is prepared through the above-mentioned tables to facilitate subsequent calls when obtaining basic information of rooms and lamps. It can be understood that the resource data can be constructed into a database, which can be a database established based on demand or other existing databases that have been constructed. The technical solution does not limit the method of establishing the database and the method of obtaining data.

[0104] S102: Based on the basic information, determine the lighting design standard of the room.

[0105] Among them, the lighting design standards of the room are determined by obtaining basic room information, such as the purpose of the room.

[0106] Specifically, the lighting design standard can be determined by preparing a list of room lighting design standards in resource data to determine the lighting design standard corresponding to the room. It can also be determined by the content specified in the General Specification for Energy Conservation and Renewable Energy Utilization in Buildings GB 55015-2021.

[0107] In this step, the determined room lighting design standards may include, for example, a standard illumination value, an LPD (Lighting Power Density) value, a reference plane height, a maintenance factor K, and the like.

[0108] S103: Obtain design requirements for lamps for the room, and determine lamps suitable for the room.

[0109] Among them, users or designers can obtain the design requirements of lamps according to their needs, which can be obtained by inputting during the design process of the room; or by setting the lamp design requirements for all designed rooms in advance, and querying the pre-set lamp design requirements during the design process of each room to achieve continuous automatic arrangement of multiple rooms. The above two input methods can be realized through the interactive interface of the program.

[0110] In addition, based on the design requirements of the lamps, the lamps suitable for the room can be automatically or manually determined, wherein the characteristic parameters of the lamps can be obtained from the lamp information list.

[0111] like Figure 4 As shown, in one embodiment of the present disclosure, in order to determine the target illumination coefficient representing the lighting positioning of the room, step S103 may further include the following steps S1031 to S1032:

[0112] S1031: Input lighting positioning.

[0113] The user can quickly select the lighting location according to the needs, that is, determine the target illumination coefficient t. With this step, the lighting needs of the room users can be more accurately met, and the designer can design the light source in the room more clearly and accurately.

[0114] The user can position the lighting of the room based on the lighting needs of the room, such as the room can be positioned as energy-saving, ordinary or comfortable, or the user can customize it within a preset range. The lighting positioning can be represented by the target illumination coefficient t. For example, for the target illumination coefficient t, the energy-saving type can be defined as t=0.95, the ordinary type as t, the comfortable type as t=1.05, and the user can customize it as 0.9≤t≤1.1.

[0115] S1032: Determine the lighting fixture information applicable to the room.

[0116] In this step, for example, information related to the lamps to be used can be determined based on the needs of the room user or the design of the designer, such as the lamp type, lamp model, installation height, lamp orientation (parallel window or vertical window, etc.), lower lamp wall distance / lamp row distance, upper lamp wall distance / lamp row distance, left lamp wall distance / lamp column distance, right lamp wall distance / lamp column distance. This information can, for example, be at least partially derived from a lamp information list or designed by the room user or designer.

[0117] Further, the comfort type is used for exemplary description, as shown in Table 5, which only lists part of the comfort type by way of example. After the comfort type lighting positioning is determined, the lamp information suitable for the room is determined.

[0118]

[0119]

[0120] Table 5 Comfort type list

[0121] In this embodiment, by determining the target illumination coefficient lighting positioning, that is, determining the target illumination coefficient t, a more accurate design can be achieved.

[0122] S104: Calculating the number of target lamps, including: determining a target illumination value according to basic room information and lighting design standards; obtaining characteristic parameters of the lamps, wherein the characteristic parameters include a first group of characteristic parameters and a second group of characteristic parameters including different parameters; and calculating the number of target lamps according to the basic room information, the first group of characteristic parameters and the target illumination value.

[0123] Specifically, in order to calculate the number of target lamps, characteristic parameters of the lamps can be obtained from the resource database, and parts of the characteristic parameters can be used to calculate the number of target lamps in each step. It is understandable that in the calculation of each step, a part of the characteristic parameters can be different from or partially overlap with another part of the characteristic parameters, the second group of characteristic parameters.

[0124] like Figure 5 As shown, in one embodiment of the present disclosure, to calculate the number of target lamps, step S104 may further include the following steps S1041 to S1046:

[0125] S1041: Determine the lighting impact parameter value of the room according to the basic information of the room.

[0126] The lighting influencing parameter value of the room may include, for example, the parameters in the list established in the resource database that can affect the lighting design, such as the reflection of light by building materials. Specifically, for example, the average wall reflectance in the room may be calculated by the following formula:

[0127] According to the basic information of the room, the average wall reflectance ρ is calculated by the following method: wav :

[0128] ρ wav =[ρ w (A w -A win -A d -A g )+ρ win ×A win +ρ d ×A d +ρ g ×A g ] / A w ;

[0129] Among them, ρ w is the wall reflectance, ρ win is the window reflectance, ρ d is the door reflectance, ρ g Reflectance of wall decorations, A w is the total area of ​​the wall, A win is the window area, A d is the gate area and A g It should be noted that the above-mentioned areas can be calculated based on the basic information of the room obtained.

[0130] By determining the average wall reflectance by the above calculation method, the influence of wall reflection on the illuminance of lamps can be obtained, which is convenient for accurately calculating the arrangement of lamps. It can be understood that the above average wall reflectance is only an exemplary description. There are other parameters in the room that can affect the arrangement of lamps, which need to be selectively considered as needed and will not be elaborated in this solution.

[0131] S1042: Calculate the target illumination value:

[0132] Target illumination value = target illumination coefficient × illumination standard value.

[0133] The target illumination value in this article can be understood as the illumination value that the room lamps are expected to achieve, wherein the target illumination coefficient is determined in step S1031, and wherein the illumination standard value can be obtained from the step of determining the lighting design standard of the room.

[0134] S1043: Acquire characteristic parameters of the lamp from the lamp information list in the resource database.

[0135] Among them, the characteristic parameters of the lamps obtained from the resource database may include, for example: lamp ID, lamp type, lamp model, number of light sources, light source luminous flux, lamp rated power, lamp legend name, lamp family name, lamp type name, maximum allowable column height ratio of the lamp, maximum allowable row height ratio of the lamp, etc.

[0136] S1044: Determine the maximum number of lamps in the room based on basic information of the room, the target illumination value, and a first group of characteristic parameters of the lamps.

[0137] Calculate the maximum number of lamps Nmax according to the following formula:

[0138] Nmax=LPD×A / Pe;

[0139] Among them, LPD is the maximum limit of the lighting power density of the room and can be obtained from the room lighting design standard list, A is the room area and is calculated based on the basic information of the room, Pe is the rated power of the lamp and can be obtained from the lamp information list according to the lamp model determined in step S1032.

[0140] It should be noted that when the result calculated according to the above formula is not an integer, it is rounded down.

[0141] S1045: Determine the target number of lamps based on basic room information, a list of room lighting design standards, lighting influencing parameter values, characteristic parameters of lamps, and target illumination values.

[0142] In this step, in order to calculate the target number of lamps, it is necessary to determine the utilization coefficient U, which is obtained by:

[0143] According to the basic information of the room, calculate the room shape index RI of the current room:

[0144] RI = room length × room width / [(luminaire installation height - reference plane height) × (room length + room width)].

[0145] The room shape index of the current room is determined by the above calculation method, and the room shape index is used as a condition for querying the utilization coefficient list to determine the utilization coefficient.

[0146] Then, for example, the utilization coefficient U corresponding to the current design situation can be determined from the utilization coefficient table of this article based on the room shape index RI, the reflectance of the corresponding building materials, and the lighting information.

[0147] Then, according to the following formula, the number of target lamps is calculated by rounding up to an integer, that is:

[0148] Target number of lamps = target illumination × room length × room width / (nφUK);

[0149] Where n is the number of light sources in a luminaire, φ is the luminous flux of the light source, and K is the maintenance factor and can be obtained from the standard list of room lighting design.

[0150] S1046: Determine: If the target number of lamps is greater than the maximum number of lamps, make the target number of lamps equal to the maximum number of lamps.

[0151] S105: Based on the target number of lamps, determine the number of rows and columns of lamps, wherein the lamp uniformity requirement is determined according to another part of the characteristic parameters; determine the first row number and the first column number that first meet the lamp uniformity requirement based on the target number of lamps in a descending manner, and calculate the first illuminance value corresponding to the first row number and the first column number; determine the second row number and the second column number that first meet the lamp uniformity requirement based on the target number of lamps in an increasing manner, and calculate the second illuminance value corresponding to the second row number and the second column number; subtract the first illuminance value and the second illuminance value from the target illuminance value respectively, and take the row number and column number corresponding to the smaller absolute value as the final row number and column number.

[0152] like Figure 6 As shown, in one embodiment of the present disclosure, in step S105, the uniformity requirement of the lamps may be determined by the optimal ratio of column spacing to row spacing, and step S105 may therefore further include the following steps S10511 to S10516:

[0153] S10511: Determine the allowable illumination range based on the illumination standard value.

[0154] The illuminance range is based on the standard illuminance value and is obtained by floating up and down. For example, the illuminance range can be between 0.9 and 1.1. Therefore, the upper limit of the illuminance range is 1.1× the standard illuminance value, and the lower limit is 0.9× the standard illuminance value. It should be understood that this range is specified in the current national standard "Architectural Lighting Design Standard" GB 50034-2013.

[0155] S10512: Determine the optimal column spacing to row spacing ratio as follows:

[0156] The optimal ratio of column spacing to row spacing = maximum lamp column spacing ÷ maximum lamp row spacing.

[0157] The above formula can be further derived as:

[0158] The optimal column spacing and row spacing ratio crr = maximum lamp column spacing ÷ maximum lamp row spacing = (maximum allowable lamp column height ratio × hr) ÷ (maximum allowable lamp row height ratio × hr) = maximum allowable lamp column height ratio ÷ maximum allowable lamp row height ratio.

[0159] Among them, the optimal ratio of column spacing to row spacing, the maximum allowable column height ratio of the lamp and the maximum allowable row height ratio of the lamp can be obtained from the characteristic parameters of the lamp.

[0160] It should be noted that the maximum allowable row height ratio of lamps is the ratio of the maximum row spacing formed between two lamps to the hanging height hr of the lamps to the working surface.

[0161] The maximum allowable row-to-height ratio of lamps is the ratio of the maximum row spacing formed between two lamps to the hanging height hr of the lamp to the work surface.

[0162] Among them, the hanging height is the distance between the working surface of the lamp and the ground.

[0163] S10513: Decrease based on the target number of lamps, and based on the decreased number of lamps, determine the combination of the number of columns and the number of rows that is closest to the optimal column spacing and row spacing ratio. If the determined number of rows and columns meets the first lamp uniformity requirement, then the number of rows and the number of columns are determined as the first number of rows and the first number of columns, and the first illuminance value corresponding to the first number of rows and the first number of columns is calculated. Otherwise, repeat the cycle until the number of lamps reaches the preset minimum value.

[0164] The number of columns and rows that can be formed after the number of target lamps changes successively are obtained by decreasing the number of target lamps to the preset minimum value. The number of each decrease is i, which can be a fixed value, such as 1. The number of target lamps after 1 is reduced is allocated to determine the number of columns and rows that can be formed. The preset minimum value can be freely set by the user, and can be set to 1, for example, that is, the minimum number of target lamps is 1.

[0165] Among them, in this loop, determine the combination of the number of rows and columns that is closest to the optimal column pitch-to-row pitch ratio among the possible number of columns and rows corresponding to the current (decreasing) number of luminaires, and if the luminaires in this number of rows and columns can meet the first luminaire uniformity requirement of the first room (the first room can be, for example, a non-corridor room here), then exit the loop.

[0166] Among them, in this article, the first luminaire uniformity requirement is characterized by the luminaire uniformity limit value, and the luminaire uniformity limit value characterizes the limit of the deviation of the acceptable column pitch-to-row pitch ratio of the luminaires relative to the optimal column pitch-to-row pitch ratio. Specifically, the first luminaire uniformity requirement can be calculated through the first uniformity coefficient uni1, where, for example, 0 < uni1 ≤ 1. Currently, if (column pitch / row pitch) satisfies: (optimal column pitch-to-row pitch ratio * uni1) ≤ (column pitch / row pitch) ≤ (optimal column pitch-to-row pitch ratio / uni1), then the luminaires meet the luminaire uniformity requirement of the non-corridor room.

[0167] If the number of columns and rows meets the first luminaire uniformity requirement, then exit the loop, and mark the number of columns and rows as the first number of columns and the first number of rows respectively.

[0168] Among them, calculate the first illuminance value corresponding to the first number of columns and the first number of rows, where the first illuminance value is the average illuminance Eav and its calculation formula is as follows:

[0169] Eav = N × φ × U × K ÷ A = L × n × φ × U × K ÷ A;

[0170] Among them, N is the number of light sources, L is the number of luminaires, n is the number of light sources in each luminaire, φ is the luminous flux of the light source, U is the utilization factor, K is the maintenance factor, and A is the room area.

[0171] S10514: Increase based on the target number of luminaires. Based on the increased number of luminaires, determine the combination of the number of columns and rows that is closest to the optimal column pitch-to-row pitch ratio. If the determined number of rows and columns meets the first luminaire uniformity requirement, then determine the number of rows and columns as the second number of rows and the second number of columns, and calculate the second illuminance value corresponding to the second number of rows and the second number of columns. Otherwise, repeat this loop until the target number of luminaires is equal to the maximum number of luminaires. If the first luminaire uniformity requirement is still not met in the case of the maximum number of luminaires, then set the second number of rows and the second number of columns equal to the first number of rows and the first number of columns.

[0172] As Fig. 8A shown, similar to step S10513, the increment each time is i, and i can be a fixed value, for example, 1. Allocate the target number of luminaires after adding 1 to determine the possible combinations of the number of columns and rows.

[0173] In this loop, the row and column combination that is closest to the optimal column spacing to row spacing ratio among the possible number of columns and rows corresponding to the current (incrementing) number of lamps is determined, and if the lamps of this row and column can meet the first lamp uniformity requirement of the room (the room can be a non-corridor room, for example), the loop is exited. The number of rows of lamps here is set to the second number of rows and the number of columns of lamps is set to the second number of columns.

[0174] Then, a second illumination value corresponding to the second column number and the first row number is calculated according to the above formula.

[0175] If the number of rows and columns still does not meet the first lamp uniformity requirement of the lamps until the target number of lamps is increased to reach the maximum number of lamps, the values ​​of the second number of rows and the second number of columns are respectively set to be equal to the first number of rows and the first number of columns.

[0176] S10515: Judgment:

[0177] If the first illuminance value is less than the lower limit of the allowable illuminance range, the third row number and the third column number are set equal to the second row number and the second column number; if the first illuminance value is greater than or equal to the lower limit of the allowable illuminance range, and if the second illuminance value is less than or equal to the upper limit of the allowable illuminance range, the first illuminance value and the second illuminance value are respectively subtracted from the target illuminance, and the row number and column number corresponding to the smaller absolute value are set as the third row number and the third column number; if the second illuminance value is greater than the upper limit of the allowable illuminance range, the third row number and the third column number are set equal to the first row number and the first column number.

[0178] S10516: Set the third column number and the third row number as the final column number and row number.

[0179] It should be noted here that: the present invention innovatively introduces the optimal ratio of column spacing to row spacing as the basis for lamp uniformity for the first time, and innovatively introduces the lamp uniformity limit value as the lamp uniformity requirement, so that it can automatically determine whether the number of rows and columns of a group of lamps meets the lamp uniformity requirement. And by automatically decreasing and increasing the number of lamps, the number of rows and columns of lamps that not only meet the lamp uniformity requirements but also are closest to the target illumination can be calculated within the range of plus or minus 10% of the illumination standard value specified in the lighting specification. Compared with the prior art, the number of rows and columns calculated by this method can automatically and more accurately meet the requirements of lamp uniformity and illumination, improve the accuracy of the design, and simplify the designer's work.

[0180] In a preferred embodiment of the present invention, the following steps may be included after step S10516. Figure 7 and Figure 8B As shown, Figure 8B The top and bottom in and out on the left side correspond to Fig. 8A Output and input at the bottom on the right side.

[0181] S10517: Calculate the third illuminance value corresponding to the numbers in the third row and the third column. This calculation is the same as the methods for calculating the first and second illuminance values, so it will not be elaborated here.

[0182] S10518: Judge:

[0183] If the third illuminance value is greater than or equal to the lower limit of the allowable illuminance range, set the numbers in the third row and the third column as the final row and column numbers; otherwise, reduce the requirement for the uniformity of the lamps, that is, set the second requirement for the uniformity of the lamps as the standard for judging the uniformity, where the second requirement for the uniformity of the lamps is less than the first requirement for the uniformity of the lamps, and return to step S10513 for processing until the third illuminance value corresponding to the determined numbers in the third row and the third column is greater than or equal to the lower limit of the allowable illuminance range.

[0184] It should be noted here that: the second requirement for the uniformity of the lamps can be calculated through the second uniformity coefficient uni2. For example, the second requirement for the uniformity of the lamps can be the requirement for the uniformity of the corridor lamps, where 0 < uni2 < uni1, representing the limit of the deviation of the (column pitch / row pitch) of the lamps acceptable in the room compared to the optimal column pitch and row pitch ratio. If the (column pitch / row pitch) satisfies: (optimal column pitch and row pitch ratio * uni2) ≤ (column pitch / row pitch) ≤ (optimal column pitch and row pitch ratio / uni2), then the lamps meet the second requirement for the uniformity of the lamps.

[0185] It should be noted that: if the number of rows and columns of the lamps calculated in this step still do not meet the illuminance requirements, the requirement for the uniformity of the lamps can be further reduced, for example, setting a third requirement for the uniformity of the lamps less than the second requirement for the uniformity of the lamps, and so on, until the number of rows and columns that meet the requirements is obtained.

[0186] Generally, the requirements for the uniformity of the lamps have different values for different rooms, such as functional rooms like regular offices and corridors. The requirements for the uniformity of the lamps in regular rooms are more stringent than those in corridors. This method first determines the number of rows and columns according to the high requirements for the uniformity of the lamps. When the requirements for the uniformity of the lamps cannot be met, it is then relaxed to the lower requirements for the uniformity of the lamps for calculation, so as to determine the number of rows and columns that meet the requirements, and make this method universal for rooms with different requirements for the uniformity of the lamps.

[0187] S106: Based on the final number of rows and columns and the basic information, determine the positions of the corresponding lamps in the room.

[0188] Among them, based on information such as the width and length of the room and the obtained final number of rows and columns, determine the positions of the lamps in the room. The specific calculation methods are as follows:

[0189] Calculate row spacing = room width / [number of rows - 1 + (lower lamp wall distance / lamp row spacing) + (upper lamp wall distance / lamp row spacing)];

[0190] Calculate the distance between the lowest row of lights and the wall = row spacing × (lower light wall distance / light row spacing);

[0191] Calculate the row spacing = room length / [number of rows - 1 + (left lamp wall distance / lamp row spacing) + (right lamp wall distance / lamp row spacing)];

[0192] Calculate the distance between the leftmost row of lights and the wall = row spacing × (left light wall distance / light row spacing);

[0193] Among them, the upper light wall distance and the lower light wall distance respectively represent the distance between the row of lights closest to the wall among the number of rows that the lamps can form. For example, if there are 4 rows in total, the distances between the first row and the fourth row and the corresponding walls are the upper light wall distance and the lower light wall distance. The left light wall distance and the right light wall distance can also be understood as the distance between the column of lights closest to the wall among the number of columns that the lamps can form.

[0194] The position of the lower left lamp is the lower left vertex of the room offset along the row direction by the distance of the left column lamp from the wall, and then offset along the column direction by the distance of the lower column lamp from the wall. This is achieved by vector operation.

[0195] Taking the lower left lamp as the reference, the column spacing is offset one by one along the row direction to obtain the position of each lamp in the lower row; taking the lower row lamp as the reference, the row spacing is offset one by one along the column direction to obtain the position of each lamp.

[0196] Additionally, in an alternative embodiment, a step S107 of placing a lamp may be further included.

[0197] Step S107: Based on the obtained position of each lamp, place the lamp in the room.

[0198] Among them, according to the lamp setting information calculated or determined above, such as the installation height of the lamp in the room, the lamp orientation (such as parallel window or vertical window), the lamp block name or component name and the component type name, each lamp is inserted into the design file, such as inserting each lamp block into the CAD drawing, or placing the component type into the BIM model, so as to present the position of the lamp in the CAD drawing or the BIM model.

[0199] The final number of rows and columns obtained through the above calculations, combined with the basic information, can determine the position of the corresponding lamp in the room. This method has a high degree of automation and precise design, which can improve work efficiency.
