04, the display 106, the printer 108, and the memory 112.

The CPU 110 controls the entire lighting equipment drawing creation support device in accordance with the automatic arrangement program 114 stored in the memory 112. Generally, a ROM or a RAM as a main storage device is used as the memory 112. In addition to the automatic layout program 114, the architectural drawing input file 1
16, room input file 118, group information file 120, room information file 122, room attribute file 1
24, vertical arrangement ratio data 126, horizontal arrangement ratio data 128, and the like are stored. Note that this automatic placement program is a part of a large-scale system program (that is, a subroutine program, etc.) like a CAD program.
Or may be a single program. The memory 112 is not limited to ROM and RAM,
It may be an external storage device such as a flexible disk, a hard disk, or a magneto-optical disk, and these devices may be used in combination with the ROM or RAM.

Here, the architectural drawing input file 116 is
It is a file that stores data of architectural drawings read by the scanner 104. Here, the "architectural drawing" is a plan view of the building, and shows what is drawn by partition lines such as windows, walls and doors. The “architectural drawing data” is information on architectural drawings to be handled by the lighting equipment drawing creation support device. The room input file 118 is a file that stores a plurality of sections forming one room in the architectural drawing. Here, "one room" means a space partitioned by walls, columns, beams, etc. in an architectural drawing.

The group information file 120 is a file that specifies a partition forming one room among the partitions stored in the room input file 118. The room information file 122 is a file that stores design illuminance and the like that differ for each type of room. Room attribute file 124
Is a file that sets different grades of lighting equipment for each building business type. In addition, the contents of these files,
Details of the vertical arrangement ratio data 126 and the horizontal arrangement ratio data 128 will be described later.

Further, the keyboard 100 and the mouse 102 are devices embodying the partition inputting means, the reference designating means, the shape inputting means, and the ratio changing means.
This is a device for inputting a plurality of rectangular sections that form the room. Various types of input data are stored in the memory 112 via the bus 130. Note that a pointing device such as a digitizer, a tablet, a trackball, a light pen, or a joystick may be applied instead of (or in combination with) the keyboard 100 and the mouse 102. Further, the scanner 104 converts the contents of the architectural drawing for use by the assisting device and stores it in the architectural drawing input file 116 of the memory 112 via the bus 130. The contents of the architectural drawing may be directly input by the operator using the keyboard 100, the mouse 102 or the like and stored in the architectural drawing input file 116 of the memory 112. Alternatively, instead of the scanner 104, a device such as a flexible disk or a magneto-optical disk is connected, the data showing the content of the architectural drawing recorded in a predetermined format is read, and the architectural drawing of the memory 112 is input via the bus 130. It may be configured to be stored in the file 116.

Then, the display 106 and the printer 1
Reference numeral 08 is one of the devices each embodying the output device. On the display 106, the read architectural drawing and / or the lighting equipment to be described later are displayed, and similarly, the architectural drawing and / or the lighting equipment and the like are printed on a printing paper or the like by the printer 108. A plotter may be used instead of the printer 108. It should be noted that all of the above components are coupled to the bus 130.

The processing procedure for realizing the present invention in the support apparatus having the above-described configuration will be described with reference to FIGS.
Will be described with reference to. Here, the flowcharts shown in FIGS. 3, 6, 8 and 9 show a series of processing procedures, which are realized by the CPU 110 executing the automatic placement program 114. Note that steps S32 and S34
Is a processing step that embodies the arrangement interval calculation means,
Steps S36, S44, and S86 are processing steps that embody the facility placement means, and step S20 is a processing step that embody the output means. In addition, FIG.
In the connectors A and B shown in FIG. 8 and FIG. 8, the processing procedure is continuous.

In FIG. 3, first, the operator reads the contents of the architectural drawing with the scanner 104 (step S10). By this reading, the contents of the architectural drawing are stored in the memory 112 as the architectural drawing input file 116 and also displayed on the display 106.

Next, while looking at the architectural drawing displayed on the display 106, the operator operates the keyboard 100.
Alternatively, the mouse 102 is used to input a rectangular section that forms one room (step S12). For example, for two points on the diagonal of a rectangular section, the keyboard 100
The coordinate data is input from or the point is specified by using the mouse 102. The section information thus input is stored in the room input file 118 and is displayed on the display 106. Where room input file 1
An example of the configuration of one element in 18 is shown in FIG. This element 300 is composed of a section number 302 that is sequentially assigned each time it is input, and position information 304 including at least a frontage, a depth, and a ceiling height.

For example, in the case of the room 200 having a concave shape shown in FIG. 4, there are a horizontally long section 206 and sections 202 and 204 adjacent to the upper section thereof as shown in FIG. 4 (A). In this case, the section 202 and the section 206 are adjacent to each other, and the section 204 and the section 206 are adjacent to each other. Similarly, FIG.
As shown in (B), vertically long sections 212, 21
There are cases of 4,216. In this case, the partition 212 and the partition 216 are adjacent to each other, and the partition 216 and the partition 214 are adjacent to each other. For ease of explanation in FIG. 4 and FIG. 7 described later, the room 200 and the partition 202 are not shown in an overlapping manner, but in reality, a part of the shape of the partition 202 is part of the room 200. It is input so as to overlap with a part of the shape.

Returning to FIG. 3, the operator selects a section forming one room from the sections input in step S12 (step S14). In this selection, in order to simplify the operation, it is desirable to click the section input in step S12 with the mouse 102. The section thus selected is the room input file 11
The partition number obtained by referring to 8 is stored in the group information file 120. Specifically, when the selection is performed for the first time after executing this processing procedure, the group information file 120 is generated in the memory 112, and thereafter, new data is added to the group information file 120.

Here, a structural example of one element in the group information file 120 is shown in FIG. 5 (B). This element 3
10 is a group number 3 which is added in order for each selection
12, reference section number 314, each section number selected 3
16, ..., 31n. The partition numbers obtained from the room input file 118 by the above selection are stored in the partition numbers 316, ..., 31n.

Further, returning to FIG. 3, the operator designates a section to be a reference when arranging the lighting equipment, with respect to the section selected in step S14 (step S1).
6). The designation method is preferably the same as that in step S14. For the designated reference section (hereinafter referred to as “reference section”), the section number obtained by referring to the room input file 118 is stored in the reference section number 314 of the group information file 120. .

When the reference section is designated, the process for arranging the lighting equipment is started (step S1).
8). The contents of the processing will be described with reference to FIGS. 6 to 8. Hereinafter, description will be made on the assumption that the vertically long partitions 212, 214, and 216 shown in FIG. 7A similar to FIG. 4B are selected and the partition 212 is designated as the reference partition. In addition, sections other than the reference section (sections 214, 216)
Will be referred to as a "dependent section". Further, the shape and section of the room, the lighting equipment, and the like shown in FIGS. 4 and 7 are displayed on the display 106 together with the architectural drawing.

In FIG. 6, first, room information on the reference section designated in step S16 (ie, the reference section number 314 above) is acquired (step S).
30). That is, necessary data is acquired from the room input file 118, the room information file 122, and the room attribute file 124 stored in the memory 112. Less than,
These room information file 122 and room attribute file 1
The contents of 24 will be described.

FIG. 5 shows one element of the room information file 122.
It shows in (C). This one element 320 is the building type code 3
22, room attribute code 324, lighting equipment grade 32
6, design illuminance 328, work surface height 330, reflectance 332
It is composed by. Here, the "building business" indicates the purpose of the building, and corresponds to, for example, a school, a hotel, an office building, or the like. The "room attribute" indicates the purpose of the room, and corresponds to, for example, a conference room or a corridor. In addition, the "building type code" is a unique code (expressed in a discrete format and includes numerical values, alphanumeric characters, symbols, etc.) assigned to each purpose of the building, and similarly, "room attribute code" Is a unique code assigned to each use of the room. Therefore, the type of room
It is determined by the building business condition code 322 and the room attribute code 324. Therefore, if the building type is the same, but the room attribute is different, or conversely, if the building type is the same, but the building type is different, the type of room is different.

The "grade" is the degree of high grade of lighting equipment, and as will be described later, for example, high grade,
There are middle grade and low grade. The "design illuminance" is a standard illuminance required for the room being designed, and changing this value makes the entire room brighter or darker. "Working surface height" is a height that achieves design illuminance. For example, if it is a corridor, 0m (floor surface)
Is set as the initial value, and 0.85m for the office
(Standard office desk height) is set as the initial value. The “reflectance” means the reflectance of each of the ceiling, wall, and floor of the room, and by changing this value, it is possible to match the usage pattern of the room. For example, in a room where it is known that a carpet or wallpaper having a color tone darker than the standard is used, the reflectance value may be appropriately reduced.

On the other hand, one element of the room attribute file 124 is shown in FIG. This one element 340 is a building business type code 342, a room attribute code 344, high-grade lighting equipment data 346, and middle-grade lighting equipment data 3.
48, low-grade lighting equipment data 350. Here, the "lighting equipment data" includes a unique code attached to each equipment such as a fluorescent lamp and an emergency light, that is, a lighting equipment code. Display 1
The symbols displayed on the printing paper or the like printed by the printer 06 or the printer 108 differ according to the lighting equipment code. Also, in the lighting equipment data, in addition to the above lighting equipment code,
The size of lighting equipment is included. The operator can also set whether or not to include the size of the lighting equipment in the lighting equipment data.

For example, when the room attribute is a corridor, and the building business type is a hotel, downgrade embedded cover type lighting equipment is used for high-grade lighting equipment.
Downlight embedded open type lighting equipment is used for middle grade lighting equipment, and embedded open type fluorescent lamps are used for low grade lighting equipment. On the other hand, even if the room attribute is a corridor, if the building type is an office building, embedded fluorescent lamps with opalescent acrylic are used for high-grade lighting equipment and embedded type for middle-grade lighting equipment. The open bottom type fluorescent lamp is used, and the V type lighting equipment is used for the low grade lighting equipment. In this way, it is possible to arrange appropriate lighting equipment according to the type of room.

The data in the room information file 122 and the room attribute file 124 are preset with initial values indicating standard values. However, the operator may input each of these data using the keyboard 100 or the like before executing step S10. The operator can also change each of these data at any time.

Returning to FIG. 6, the number of installed lighting equipments in the reference section is calculated for each of the vertical and horizontal directions (step S32). Specifically, the number of units required to realize the design illuminance 328 of the room with the lighting equipment is obtained. That is, based on the luminous flux method (design illuminance 328, room floor area, lamp luminous flux, illumination rate, maintenance rate, average illuminance calculation method based on the number of lights per lighting facility) Calculate the number of installed units.
The lighting rate is determined by the reflectance, the room index, and the fixture, and the maintenance rate is determined by the type of lighting equipment. Since the frontage and the depth can be known from the position information 304, the room index can be obtained together with these and the ceiling height. The calculation formula is shown below. Light source height = Ceiling height-Working surface height-Length of hanging lighting equipment Room index = (frontage x depth) / {light source height x (frontage + depth)}

Thus, based on the frontage (distance Lx in the horizontal and horizontal directions) and depth (distance Ly in the vertical and vertical directions) of the section 212 stored in the room input file 118, the number of lighting equipments is determined. It is calculated. For example, FIG.
When step S32 is executed for the section 212 shown in (A), it is calculated that there are four units in the vertical direction and three units in the horizontal direction.

Next, the arrangement interval of the lighting equipment is obtained, and the arrangement reference points in the reference section are determined (step S34). That is, the arrangement interval of the lighting equipment is obtained based on the number of installed lighting equipment in the vertical direction and the horizontal direction calculated in step S32, and one point in the reference section is set as the arrangement reference point. Specifically, the following processing is performed. First, the vertical arrangement ratio data 126 and the horizontal arrangement ratio data 128 are acquired from the memory 112. Then, according to the vertical arrangement ratio data 126 and the horizontal arrangement ratio data 128, the arrangement interval of the lighting equipment in the vertical direction and the horizontal direction is obtained. Regarding the arrangement intervals of the lighting equipment in the vertical direction and the horizontal direction thus obtained, for example, the position (coordinates) of the lighting equipment installed in the lower left corner of each section is used as the arrangement reference point.

The vertical arrangement ratio data 126 and the horizontal arrangement ratio data 128 are both {distance between wall and lighting equipment: distance between lighting equipment: distance between lighting equipment and wall}.
In the architectural drawing, the vertical direction (Y-axis direction) is the vertical arrangement ratio data 126, and the horizontal direction (X-axis direction) is the horizontal arrangement ratio data 128. The vertical arrangement ratio data 126 and the horizontal arrangement ratio data 128
The initial value of is set to 1: 2: 1.

In the case of FIG. 7A, when step S34 is executed for the section 212, the distance y1 in the vertical direction is calculated by the vertical arrangement ratio data 126 and the distance y1 in the ratio 1 and the distance y2 in the ratio 2 are obtained. Further, the horizontal distance Lx is calculated by the horizontal arrangement ratio data 128 to obtain the distance x1 of the ratio 1 and the distance x2 of the ratio 2. Therefore, section 212
When the lower left corner of is the origin, the coordinate position (x1, y1)
Is the center of the lighting equipment, and the lower left corner of the lighting equipment is the placement reference point 212a. The placement reference point 212a may be the coordinate position (x1, y1) that is the center of the lighting equipment, or may be another position.

Thus, the lighting equipment is arranged based on the determined number of the lighting equipment in the vertical and horizontal directions and the reference point to be arranged (step S36). Specifically, the following processing is performed. First, according to the type of lighting equipment,
Determine the placement direction. In other words, if the lighting equipment is a fluorescent lamp, the standard is to arrange it vertically to the frontage, and if the depth is exceptionally less than the length of the lighting equipment, determine the direction in which it should be arranged parallel to the long side. To do. If the lighting equipment is a downlight, the arrangement direction may be either direction. In this way, the number of lighting fixtures in the vertical direction or the horizontal direction obtained in step S32 is arranged in the determined arrangement direction. It should be noted that the operator uses the above vertical arrangement ratio data 126.
The arrangement method is not limited to the arrangement based on the horizontal arrangement ratio data 128, and an arrangement method such as uniform arrangement, zigzag arrangement, system ceiling, and connection can be selected.

Next, as in step S30, the room information about the subdivision is acquired (step S38), and the placement reference point of the subdivision is determined (step S40).
In the case of FIG. 7A, when step S40 is executed, the arrangement reference point 2 of the partition 216, which is the dependent partition in the first execution, is set.
16a and then the placement reference point 214a of the partition 214 is determined.

For example, in the case of the partition 216, starting from the layout reference point 212a of the partition 212 which is the reference partition, the vertical position obtained in step S34 is not changed, and the horizontal direction is 3 for the distance x2 of ratio 2. The position where the platform is separated becomes the arrangement reference point 216a. In other words, section 2
When the lower left corner of 12 is the origin, the coordinate position (x1 + 3
Xx2, y1) is the center of the lighting equipment, and the lower left corner of the lighting equipment is the arrangement reference point 216a of the section 216.

Similarly, in the case of the section 214, the arrangement reference point 2
Starting from 12a, the vertical position is not changed, and 5 units are arranged in the horizontal direction for a distance x2 having a ratio of 2 (in the step S42 described later, the number of lighting fixtures installed in the section 216 is 2 units in the horizontal direction). The position away from each other becomes the arrangement reference point 214a. In other words, section 212
If the lower left corner of is the origin, the coordinate position (x1 + 5xx
2, y1) is the center of the lighting equipment, and the lower left corner of this lighting equipment is the arrangement reference point 214a of the section 214.

Then, the number of installed lighting equipments in the vertical and horizontal directions in the subdivision is calculated (step S4).
2). Specifically, from the frontage and the depth of the subdivision 212 stored in the room input file 118, the above-mentioned arrangement reference point is used as a starting point, and the arrangement interval of the lighting equipment in the reference division calculated in step S34 is used as a basis. Calculate the number of units that can be installed. In the case of FIG. 7A, step S4
When 2 is executed, the number of partitions 216 is two in both the vertical and horizontal directions, and the number of partitions 214 is four in the vertical direction and two in the horizontal direction.

Thereafter, similar to step S36, based on the arrangement intervals of the illumination equipment calculated in step S34, the number of the illumination equipment in the vertical direction and the horizontal direction and the arrangement reference points of the subdivisions of the illumination equipment are set. Arrangement is performed (step S44). In this way, the processes of steps S38 to S44 for the subordinate partitions are executed until there are no unprocessed subordinate partitions (step S46). In addition, as shown in FIG. 7 (A), the lighting equipment 40 is arranged.
0 is a symbol indicating a fluorescent lamp, which is neatly aligned in the vertical and horizontal directions. Further, since the type of lighting equipment is indicated by a symbol, it is possible to recognize at a glance what kind of lighting equipment is arranged. In this way, since the lighting equipment is automatically arranged, the labor and man-hours required for the arrangement can be significantly reduced.

Next, in FIG. 8, the operator is inquired whether or not the position of the lighting equipment automatically arranged in step S36 and step S44 is proper (step S50). As a result, if it is proper (YES), returning to FIG. 3, step S20 is executed to print the drawing in which the lighting equipment is arranged (step S20). In this way, a drawing in which the type of lighting equipment and its position are superimposed on the architectural drawing is called a “lighting equipment drawing”.

On the other hand, when the position of the lighting equipment is not appropriate (NO), such as when the lighting equipment comes into contact with or overlaps with any of the sections (that is, the shape of the room), the arranged lighting equipment is deleted. Yes (step S52). For example, this corresponds to the case where some of the lighting equipment 402 and 404 shown in FIG. Note that FIG.
In (A), the shape of the room 200 and the shape of the partition 214 and the like are not shown in an overlapping manner for easy understanding,
Actually, a part of the shape of the partition 214 or the like is input by overlapping with a part of the shape of the room 200. Therefore, when the operator looks at the display 106, the lighting equipment 40
2, 404 appear to be in contact with the room 200.

Thereafter, the operator is made to input the appropriate values of the vertical arrangement ratio data 126 and the horizontal arrangement ratio data 128 using the keyboard 100 or the like (step S54). That is, the vertical arrangement ratio data 126 and the horizontal arrangement ratio data 12
Since all 8 are 1: n: 1, the ratio n of the distances between the lighting equipments is input. Specifically, FIG. 7 (A)
In the case of the arrangement of lighting equipment as shown in, the vertical direction (Y
(Axial direction) can be left unchanged, so horizontal direction (X-axis direction)
You can enter a slightly larger value for. For example, since the initial value of the horizontal arrangement ratio data 128 is 1: 2: 1, “2.2” is input so that it becomes 1: 2.2: 1. When this arrangement ratio is input, as shown in FIG. 7B, the lighting equipment 400 is arranged at the distance x3 of the ratio 1 and the distance x4 of the ratio 2.2.

Then, the input vertical arrangement ratio data 12
6 and the value of the horizontal arrangement ratio data 128, the average illuminance when the lighting equipment is arranged is obtained (step S56). This calculation process will be described with reference to FIG. In FIG. 9, first, it is checked whether the vertical arrangement ratio data 126 and the horizontal arrangement ratio data 128 input in step S54 are within the specified range (step S60). Specifically, the ratio n of the distances between the lighting facilities is, for example, 1.5 to
Inspect whether it is within the range of 2.5. The reference ratio “1.5 to 2.5” is an example, and the specified range may change depending on the type of room or lighting.

If it is within the specified range (YES), the process returns to step S30 shown in FIG. 6, and the lighting equipment is rearranged according to the input vertical arrangement ratio data 126 and horizontal arrangement ratio data 128. On the other hand, if it is outside the specified range (NO) in step S60, the number of installed units in the reference section is increased (step S62), and the average illuminance is calculated according to this result (step S64). A method of calculating the average illuminance is performed by a normal light flux method. Note that this detail is omitted because it is described in the text of the luminous flux method.

In step S60, the ratio n of the distances between the lighting equipments is inspected, but the maximum value of the distances between the lighting equipments (hereinafter referred to as "maximum equipment distance") may be inspected. That is, first, since the maximum inter-equipment distance varies depending on the type of lighting equipment, the maximum inter-equipment distance according to the type of lighting equipment is stored in the memory 112. Then, in step S60, it is checked whether or not the arrangement interval obtained in step S34 exceeds the maximum inter-equipment distance. In this case, if the maximum inter-equipment distance is not exceeded, the procedure returns to step S30 shown in FIG. 6, and if the maximum inter-equipment distance is exceeded, the procedure proceeds to step S62.
According to this procedure, since the distance between the lighting equipments is regulated according to the lighting equipments, it is possible to reliably secure the necessary illuminance for each type of lighting equipments.

Then, it is inspected whether the average illuminance calculated in step S64 is within a predetermined range, that is, whether or not the design illuminance is satisfied (step S66). If the calculated average illuminance satisfies the design illuminance (YE
S), returning to step S30 shown in FIG. 6, the lighting equipment is rearranged according to the initialized vertical arrangement ratio data 126 and horizontal arrangement ratio data 128 (for example, both ratio data are 1: 2: 1). . Regarding the arrangement of the lighting equipment as shown in FIG. 7 (A), the horizontal arrangement ratio data 128 described above.
When the input is, each lighting equipment 400 is rearranged as shown in FIG. 7 (B). In this way, the lighting equipment can be arranged in a neat manner without touching the shape of the room 200.

On the other hand, in step S66 shown in FIG. 9, if the average illuminance does not satisfy the design illuminance (N
O), after performing error processing (step S68),
The automatic placement program 114 is ended. As this error processing, for example, there is a processing of displaying a message on the display 106 that "the lighting equipment cannot be automatically arranged because the design illuminance is not satisfied." Therefore, it is possible to prevent the arrangement of lighting equipment that does not satisfy the design illuminance.

An embodiment of the lighting equipment drawing preparation support device has been described above, but the structure, shape, size, material, etc. of the other parts of this lighting equipment drawing preparation support device have been described.
The number, arrangement, operating conditions, etc. are not limited to those in this embodiment. For example, in the above-described embodiment, an example in which the invention is applied to the shape of a room having a concave shape is shown. However, the shape may be a linear shape (that is, a non-rectangular shape) such as a convex shape, a concave shape, an E shape, and an L shape. Clearly, the same applies.

Further, even in the case of the room 500 including a curved part in a part as shown in FIG. 10 (A), adjacent partitions 50 forming a rectangle in step S12 shown in FIG.
By appropriately inputting the sizes of 2,504 and 506, it is possible to arrange the lighting equipment as shown in FIG. In this example, five lighting fixtures are arranged in one vertical column in the partition 502, six lighting fixtures are arranged in three vertical columns and two horizontal rows in the partition 504, and four vertical lighting fixtures are arranged in the partition 506. Facilities are arranged. Similarly, FIG.
Even in the circular room 510 as shown in (A), the lighting equipment as shown in FIG. 11 (B) is arranged by appropriately inputting adjacent sections 512, 514, 516 which form a rectangle. It is also possible. In this example, section 5
Each of 12 and 516 has three lighting fixtures arranged in a horizontal row, and each of the compartments 514 has 15 lighting fixtures arranged in five columns and three rows.

Next, in steps S12 to S16 shown in FIG. 3, for a single non-rectangular room, a plurality of rectangular sections forming the room are input to recognize the non-rectangular shape. The configuration is such that a division is selected and a reference division is designated. Instead of this configuration, at least one process may be automated. Hereinafter, this automation method will be described with reference to FIG. Note that in FIG. 12, the same processing elements as those in FIG. 3 are denoted by the same reference numerals, and description thereof will be omitted. Also,
Step S72 is a processing step that embodies the room dividing means, and step S76 is a processing step that embodies the reference designating means.

In FIG. 12, while looking at the architectural drawing input in step S10, the operator inputs the shape of the room as a non-rectangular shape using the keyboard 100 or the mouse 102 (step S70). The room shape is divided into a plurality of rectangular sections (step S72). When executing step S70, a file storing polygon input data is stored in the memory 1 for various subsequent processes.
It is desirable to provide it on the 12th. The division of the shape of the non-rectangular room may be automatically performed as in step S72, or may be manually performed by the operator using the keyboard 100 or the like.

For example, if the room shape is input as it is along the contour of the concave room 200 shown in FIG. 4 in step S70, the room is divided into a plurality of rectangles. That is, by executing step S72, the shape of the room 200 becomes the partition 20 shown in FIG.
2, 204, 206 and the sections 212 shown in FIG.
It is divided like 214 and 216. Therefore, when the shape of a non-rectangular room is divided, a plurality of partitions made up of a plurality of combinations are generated. At the time of this division, the room input file 118 is generated and the above-mentioned data is stored. This division is possible by determining whether or not a non-rectangular line segment exists along the horizontal direction (X-axis direction) or the vertical direction (Y-axis direction). Therefore, step S72 is a processing step for automatically performing step S14 shown in FIG.

Next, while one of the sections divided in step S72 has the maximum floor area, the combination of divisions is extracted (step S74), and the section having the maximum floor area of this combination is set as the reference section. Is designated (step S76). For example, the room 200 shown in FIG.
In the example, the floor area of the section 206 shown in FIG. 4A is the largest among the divided sections. Therefore, step S
By executing 74, the sections 202 and 2 shown in FIG.
A combination of 04 and 206 is extracted. Further, by executing step S76, the section 206 is designated as the reference section. Therefore, steps S74 and S76
Is a processing step for automatically performing step S16 shown in FIG.

In this way, the combination of divisions that gives the largest floor area is extracted from the combinations of several generated areas, when the lighting equipment is arranged based on the section having the largest floor area. This is because they are most beautifully arranged. By performing the above steps S70 to S76, the operator does not have to judge the rectangles to be neatly aligned, so that the room shape can be easily input.
And it can be done quickly. Further, the input non-rectangular room is automatically divided, and the lighting equipment can be arranged so that the appearance of the room is most beautiful.

Further, in the above embodiment, the lighting equipment is simply arranged in one room (plurality of compartments), but the lighting equipment may be arranged while inspecting whether or not it interferes with the shape of the room. Good. The state in which the lighting equipment interferes with the shape of the room means that the lighting equipment is in contact with or overlaps the shape of the room. Hereinafter, this interference inspection method will be described with reference to FIG. The same processing elements as those in FIG. 6 are designated by the same reference numerals and the description thereof will be omitted.

In FIG. 13, first, step S30 to step S34 are similar to the processing procedure shown in FIG. 6, room information about the reference section is acquired, and the number of lighting equipments in the vertical and horizontal directions is calculated. Then, the placement reference point is determined. However, the lighting equipment is not arranged in step S36 shown in FIG. Next, steps S38 to S42 are similar to the processing procedure shown in FIG. 6, in which the room information about the subdivision is acquired, the placement reference point is determined, and the number of lighting fixtures in the vertical and horizontal directions is determined. calculate. However, the lighting equipment is not arranged in step S44 shown in FIG.

Then, the interference inspection is performed (step S8).
0). Specifically, first, starting from the placement reference point of the subdivision determined in step S40, the placement interval of the lighting equipment calculated in step S34, and the vertical and horizontal directions of the subdivision calculated in step S42. The position of each lighting fixture is calculated from the number of lighting fixtures. Next, whether or not the lighting equipment contacts (or protrudes from) the contours of the subdivisions based on the size of the lighting equipment acquired in step S38, starting from the obtained position of each lighting equipment. To inspect. Thus
If at least one lighting fixture touches the contour of the subdivision, it is determined that there is interference, and if all the lighting fixtures do not touch the contour of the subdivision, it is determined that there is no interference.

If there is no interference (NO), the processes of steps S38 to S42 and step S80 are
The process is executed until there are no unprocessed dependent partitions (step S84). In this way, the lighting equipment is arranged in all of the reference section and the subdivisions for the first time without the interference of the lighting equipment (step S86). After that, step S shown in FIG.
Proceeding to 50, the operator is inquired about the quality of the arrangement. On the other hand, if there is interference (YES), the arrangement ratio is changed (step S82) and the average illuminance is calculated (step S5).
6) Then, in order to rearrange the lighting equipment for the reference section and the dependent section according to the changed arrangement ratio, the process returns to step S30.

By the above-mentioned interference inspection processing, the arrangement of the lighting equipment without interference is automated, so that the labor and man-hour required for the arrangement can be further reduced. Moreover,
In a non-rectangular room, the lighting equipment can be arranged most neatly.
