Description

The present invention relates to a lighting fixture arrangement design apparatus for designing the arrangement of lighting fixtures.

Patent Document 1 discloses a device for determining the number of vertical and horizontal arrays from the required number of lighting fixtures when designing a grid arrangement of lighting fixtures (see paragraphs 0030 to 0035 of Patent Document 1). Specifically, it is as follows. First, the divisors of the required number of vehicles are obtained, and the combination of the two divisors whose product is the required number of vehicles is specified. A combination of two divisors is a candidate for the number of vertical arrays and the number of horizontal arrays. After that, when lighting fixtures are arranged in a rectangular room with the number of vertical and horizontal arrangements of each candidate in a grid pattern, the distance from the corner of the rectangular room to the nearest lighting fixture to that corner is calculated for each candidate. Ask. If the shortest distance among the distances calculated for each of these candidates exceeds a predetermined value, the value of the required number of vehicles is updated by adding 1 to the required number of vehicles, and similar calculation processing is performed again. On the other hand, if the shortest distance is equal to or less than the predetermined value, the candidate for which the shortest distance is found is determined as the design values for the number of vertical and horizontal arrangements of the lighting fixtures.

JP-A-8-87536

By the way, in the design method described in Patent Document 1, since the distance from the corner of a rectangular room to the lighting fixture closest to the corner is calculated, the design method can only be applied to a rectangular room. .

Therefore, the present invention has been made in view of the above circumstances, and the problem to be solved by the present invention is to enable the arrangement of lighting fixtures to be designed even if the planar shape of the room is not rectangular. is.

In order to solve the above problems, a lighting fixture array designing apparatus for designing a grid-like arrangement of lighting fixtures in a rectangular area circumscribing the planar shape of a non-rectangular room is designed to provide the minimum number of lighting fixtures to be installed in the rectangular area. A combination of the number of vertical arrays of lighting fixtures and the number of horizontal arrays of lighting fixtures within the rectangular area based on the minimum number of lighting fixtures obtained by the minimum number obtaining means for obtaining the minimum number of lighting fixtures and the minimum number of lighting fixtures obtained by the minimum number obtaining means. and a vertical/horizontal array number ratio calculating means for calculating the ratio between the number of vertical arrays and the number of horizontal arrays for each candidate identified by the candidate identifying means and associating the ratio with each candidate. a dimension obtaining means for obtaining the vertical dimension and the horizontal dimension of the rectangular area; an aspect ratio calculating means for calculating an aspect ratio from the vertical dimension and the horizontal dimension obtained by the dimension obtaining means; Among the ratios calculated by the array number ratio calculation means, a candidate associated with the ratio closest to the aspect ratio calculated by the aspect ratio calculation means is selected, and the number of vertical arrays and the number of horizontal arrays of the candidates are selected. and a lighting fixture model representing the shape of the lighting fixtures arranged in the rectangular area with the number of vertical arrays and the number of horizontal arrays determined by the selecting means, representing the planar shape of the room. and deletion means for deleting lighting fixture models arranged outside the plane model of the room.

According to the above, since the aspect ratio is determined from the vertical and horizontal dimensions of the rectangular area determined from the planar shape of the room, it is not necessary to specify the position of the corner of the room and the position of the lighting fixture closest to it. There is no need to find the distance from the . Therefore, even if the planar shape of the room is not rectangular, the number of vertical and horizontal arrays of the lighting fixtures can be determined, and the arrangement of the lighting fixtures can be designed.
Also, the determined ratio of the number of vertical arrays to the number of horizontal arrays is the closest to the aspect ratio of the rectangular area among the candidates. Therefore, if lighting fixtures are arranged on the ceiling of a rectangular area of a room or the like as designed, the vertical illuminance distribution and the horizontal illuminance distribution approximate each other.

Although there are a plurality of candidates for the number of combinations that are divisors of the minimum required number of vehicles, the number of candidates is small if the minimum required number of vehicles is a prime number or the like. Even in such a case, a combination of two divisors is identified as a candidate for each integer from the minimum required number to the maximum number, so the number of candidates increases. Since the number of vertical arrays and the number of horizontal arrays are determined from many candidates, the determination tends to be optimal.

Preferably, the lighting fixture array design device calculates the pitch of the vertical arrangement of the lighting fixtures by dividing the vertical dimension acquired by the dimension acquiring means by the number of vertical arrangements determined by the selecting means. and means for calculating the pitch of the horizontal arrangement of lighting fixtures by dividing the horizontal dimension acquired by the dimension acquisition means by the number of horizontal arrangements determined by the selection means.

The computer 11 generates a video signal through arithmetic processing and outputs the video signal to the display device 12 . Then, a screen according to the video signal is displayed by the display device 12 . The display device 12 and the computer 11 may be integrated or separated.
The input device 13 is, for example, a switch, keyboard or pointing device or a combination thereof. The input device 13 may be a touch panel provided on the surface of the display device 12 . When operated, the input device 13 outputs a signal to the computer 11 according to the content of the operation.

The storage unit 14 is a storage device such as a semiconductor memory or a hard disk drive. The storage unit 14 may be built in the computer 11 or may be externally attached to the computer 11 . The storage unit 14 stores a design program 20 readable and executable by the computer 11 . The design program 20 is design software that implements BIM (Building Information Modeling) and CAD (Computer-Aided Design). BIM and CAD are realized by the computer 11 executing the design program 20 .

The storage unit 14 stores design data 30 created by design software that realizes BIM and CAD. The design data 30 includes shape data for modeling each structural element of a building (foundation, column, beam, wall, slab, room, piping, etc.) and attribute data defining attributes of these structural elements. ing.

Computer 11 executes design program 20 and reads design data 30 . Then, the computer 11 arranges the model of each structural element of the building in the virtual space according to the shape data of the design data 30, and displays the model of each structural element on the display device 12 by rendering processing. As a result, a building model made up of models of each component is displayed on the display device 12 .

The design data 30 includes dimension data 31 representing the dimension of the rectangular area. A rectangular area is the outline of a plane model (plan view) of a room built in a building, and particularly the outline of a plane model (plan view) of the ceiling of the room. A rectangle means not only a rectangle but also a square.

The dimension data 31 consists of vertical dimension data 32 representing the length of the vertical sides of the rectangular area and horizontal dimension data 33 representing the length of the horizontal sides of the rectangular area. If the rectangle is a rectangle, the long sides of the rectangle are the vertical sides and the short sides are the horizontal sides. If the rectangle is a square, the vertical dimension data 32 and the horizontal dimension data 33 are the same. Hereinafter, as shown in FIG. 2, the value of the vertical dimension data 32 is represented as A [m], and the value of the horizontal dimension data 33 is represented as B [m].

The design data 30 also includes minimum required number data 35 representing the minimum required number (model number) of lighting fixtures to be installed in the rectangular area. The required minimum number data 35 is obtained by rounding up the decimal point of the value calculated from the area of the rectangular area, the vertical dimension, the horizontal dimension, the brightness of the lighting equipment, etc., by the average illumination method. The value of the minimum required number data 35 is an integer of 1 or more. Hereinafter, the value of the minimum required number of units data 35 is assumed to be M [units].

The design data 30 also includes shape data 36 representing the planar shape of the lighting fixtures installed in the rectangular area. The computer 11 can arrange the lighting fixture model on a two-dimensional plane according to the shape data 36 .

The design program 20 includes an array design program 21 for designing an array of lighting fixtures. The arrangement design program 21 causes the computer 11 to execute processing described below, and the arrangement of the lighting fixtures is designed by the computer 11 .

2. Processing Executed by Computer Processing executed by the computer 11 according to the array design program 21 will be described.

(1) Acquisition Processing of Required Minimum Number of Units First, the computer 11 reads the required minimum number of units data 35 from the storage unit 14 and acquires the value (M) of the required minimum number of units data 35 . Note that the minimum required number may be input to the computer 11 by the user operating the input device 13 . Then, the computer 11 acquires the minimum required number data 35 with the minimum required number as a value.

(2) Process for Specifying Number of Arrangement Candidates Next, the computer 11 specifies candidates for the number of arrangements from the minimum required number data 35 in the following (2-1) to (2-3). The number of arrays refers to a combination of the number of vertical arrays and the number of horizontal arrays. The number of vertical arrays refers to the number of lighting fixtures arrayed in the long side direction of the rectangular area that is the shape of the ceiling of the room. The number of horizontal arrays refers to the number of lighting fixtures arrayed in the direction of the short side of the rectangular area that is the shape of the ceiling of the room.

(2-1) Identifying the Range of Number of Vehicles to be Considered First, the computer 11 calculates the upper limit number of vehicles by multiplying the value of the minimum required number of vehicles data 35 by a predetermined constant and rounding up the product after the decimal point. Hereinafter, the value of the upper limit number is represented as N, and the value of the predetermined constant is represented as α. α>1, preferably α=1.1. The upper limit number refers to the maximum number of units to be considered when determining the arrangement of lighting fixtures to be installed in a rectangular area. The minimum required number is the minimum value in the range of the number of vehicles to be considered.

Computer 11 then identifies the sequence of integers from M to N. Each integer in this sequence represents the number of vehicles under consideration.

When M=36 and α=1.1, N=40 and the sequence of integers is (36, 37, 38, 39, 40).

(2-2) Identifying Combinations of Divisors Next, the computer 11 obtains divisors for each integer in the series from M to N, and identifies combinations of two divisors whose product is each integer. These combinations are candidates for the number of arrays, and the larger divisor in each combination is the number of vertical arrays, and the smaller divisor is the number of horizontal arrays.
By the way, when M, which is the value of the minimum required number data 35, is a prime number, etc., the number of combinations of divisors of M is small. Even in that case, combinations of two divisors whose products are integers from M to N are identified, so the number of combinations (number of candidates) increases.

When M = 36 and α = 1.1, the number of arrays is expressed as (number of vertical arrays, number of horizontal arrays). ), (9, 4), (6, 6), (37, 1), (38, 1), (19, 2), (39, 1), (13, 3), (40, 1), (20, 2), (10, 4) and (8, 5).

(2-3) Excluding or Adding Candidates When M=1 and α=1.1, the computer 11 excludes (2, 1) from the array number candidates.
When M=2 and α=1.1, the computer 11 excludes (3, 1) from the candidates for the number of sequences.
When M=7 and α=1.1, the computer 11 adds (3, 3) to the array number candidates.
When M=10 and α=1.1, the computer 11 adds (4, 3) to the candidate number of sequences.
When M=13 and α=1.1, the computer 11 adds (4, 4) to the candidate array numbers.
When M=17 and α=1.1, the computer 11 adds (5, 4) to the candidate number of sequences.
When M=21 and α=1.1, the computer 11 adds (5, 5) to the candidate sequence numbers.
When M=26 and α=1.1, the computer 11 adds (6, 5) to the candidate sequence numbers.
It should be noted that it is not necessary to exclude and add candidates for the number of arrays as described above.

(2-4)
Note that the correspondence table obtained according to the algorithm of the processes (2-1) to (2-3) above may be recorded in the storage unit 14 in advance. The correspondence table associates the number of units with candidates for the number of arrays. In this case, when the computer 11 acquires the minimum required number data 35 as in the process of (1) above, it refers to the correspondence table to find a candidate for the number of arrays associated with M in the minimum required number data 35. Identify.

(3) Processing for Calculating the Ratio of the Number of Vertically Arranged Numbers and the Number of Horizontally Arrayed Once the candidate for the number of arrays is specified as described above, the computer 11 calculates the ratio of the number of vertically arranged to the number of horizontally arranged for each of the candidates for the number of arrays. That is, the computer 11 divides the number of vertical arrays by the number of horizontal arrays for candidates for the number of arrays. Thereby, the computer 11 associates the ratio of the number of vertical arrays to the number of horizontal arrays with each candidate for the number of arrays. Hereinafter, this ratio will be referred to as the length-to-width arrangement number ratio.

When M = 36 and α = 1.1, the correspondence between the number of vertical arrays, the number of horizontal arrays, and the ratio of the number of vertical and horizontal arrays is expressed as (number of vertical arrays, number of horizontal arrays, ratio of vertical and horizontal array numbers). is (36, 1, 36.00), (18, 2, 9.00), (12, 3, 4.00), (9, 4, 2.25), (6, 6, 1.00), (37, 1, 37.00) ), (38, 1, 38.00), (19, 2, 9.50), (39, 1, 39.00), (13, 3, 4.33), (40, 1, 40.00), (20, 2, 10.00), (10, 4, 2.50) and (8, 5, 1.60).

(4) Dimension Acquisition Processing Next, the computer 11 reads and acquires the dimension data 31 consisting of the vertical dimension data 32 and the horizontal dimension data 33 from the storage unit 14 .
Note that the user may input the value of the vertical dimension data 32 and the value of the horizontal dimension data 33 to the computer 11 by operating the input device 13 . Then, the computer 11 acquires vertical dimension data 32 and horizontal dimension data 33 .

(5) Aspect Ratio Calculation Processing Next, the computer 11 calculates an aspect ratio from the vertical dimension data 32 and the horizontal dimension data 33 . That is, the computer 11 divides A by B and determines the quotient as the aspect ratio.
The aspect ratio is 2 when A=20.0 and B=10.0.

(6) Selection process from candidates for the number of arrays Next, the computer 11 selects the aspect ratio that is closest to the aspect ratio calculated in the process (5) above among the ratios of the number of vertical and horizontal arrays calculated in the process (3) above. Identify a value. Then, the computer 11 selects the number of arrays associated with the value closest to the aspect ratio from among the candidates for the number of arrays, and determines the number of arrays. Hereinafter, the number of vertical arrays among the determined number of arrays is expressed as a [units], and the number of horizontal arrays is expressed as b [units].
Next, computer 11 calculates the product of a and b. This product represents the total number of luminaires to be installed within the rectangular area.

When M=36, .alpha.=1.1, A=20.0, and B=10.0, the value of the vertical-to-horizontal arrangement number closest to the aspect ratio of 2 is 2.25. Therefore, the number of arrays selected by the computer 11 is a=9 and b=4.

(7) Result Display Processing Next, the computer 11 causes the display device 12 to display the determined number of vertical arrays, the determined number of horizontal arrays, and the product thereof. That is, the computer 11 causes the display device 12 to display a, b and their product.
At the same time, the computer 11 causes the display device 12 to display the value of the vertical dimension data 32 and the value of the horizontal dimension data 33 . That is, the computer 11 causes the display device 12 to display A and B. FIG.

(8) Vertical arrangement pitch calculation process Next, the computer 11 calculates the vertical arrangement pitch of the lighting fixtures based on the acquired vertical dimension data 32 and the selected number of vertical arrangements. Specifically, the computer 11 divides A by a and determines the quotient as the vertical arrangement pitch. Hereinafter, the calculated vertical arrangement pitch is represented as C[m].

(9) Calculation Process of Horizontal Array Pitch Further, the computer 11 calculates the horizontal array pitch of the lighting fixtures based on the acquired horizontal dimension data 33 and the selected number of horizontal arrays. Specifically, the computer 11 divides B by b and determines the quotient as the horizontal pitch. Hereinafter, the calculated horizontal arrangement pitch is represented as D [m].

(10) Calculation of the distance from the horizontal side of the rectangular area to the horizontal arrangement of the lighting fixtures. to the horizontal array of luminaires closest to it. Specifically, the computer 11 divides A by twice a and determines the quotient as the vertical distance. Hereinafter, the calculated vertical distance is represented as E [m]. Note that E=C/2.

(11) Calculation of the distance from the vertical side of the rectangular area to the vertical arrangement of the lighting fixtures Next, the computer 11 calculates the vertical dimension of the rectangular area based on the obtained horizontal dimension data 33 and the selected number of horizontal arrangements. Calculate the horizontal distance from the side to the nearest column of luminaires. Specifically, computer 11 divides B by twice b and defines the quotient as the lateral distance. Hereinafter, the calculated vertical distance is represented as F [m]. Note that F=D/2.

(12) Drawing process Next, as shown in FIG. 3, the computer 11 expresses the positions of the vertices of the rectangular area on the plane using a two-dimensional orthogonal coordinate system, and the length of the vertical side is A. A rectangular area 90 having a horizontal side length of B is arranged on a plane.

Next, the computer 11 expresses the position of a point 92, which is vertically separated by E and laterally by F from the vertex 91 of the rectangular area 90 to the inside of the rectangular area 90, by a two-dimensional orthogonal coordinate system, and the point Set 92 on a plane.

Next, the computer 11 reads the shape data 36 and arranges a plurality of lighting fixture models 93 in a grid pattern on a plane according to the shape data 36 . Here, the computer 11 arranges the lighting fixture models 93 vertically with a pitch of C, and arranges them horizontally with a pitch of D, using the point 92 as a reference. Regarding the orientation of the lighting fixture model 93 , the longitudinal direction of the lighting fixture model 93 may be parallel to the vertical side of the rectangular area 90 , or the longitudinal direction of the lighting fixture model 93 may be parallel to the horizontal side of the rectangular area 90 . may be parallel to

Next, the computer 11 causes the display device 12 to display the a×b lighting fixture model 93 arranged as described above and the rectangular area 90 arranged as described above on the display device 12 by rendering processing. The image displayed on the display device 12 is a CAD drawing. That is, the rectangular area 90 is the plane model (plan view) of the room, the outline of the rectangular area 90 is the outline of the plane model of the room, and the lighting fixture model 93 is a model of the lighting fixture.

3. Advantageous Effect (1) An optimal arrangement of lighting fixtures is automatically calculated from the dimension data 31 and the minimum required number data 35 . That is, if the value (A) of the vertical dimension data 32, the value (B) of the horizontal dimension data 33, and the value (M) of the minimum required number data 35 are determined, the value (a) of the number of vertical arrays and the number of horizontal arrays value (b), pitch value of vertical array (C), pitch value of horizontal array (D), value of vertical distance from horizontal side of rectangular area to horizontal array (E), vertical distance of rectangular area The computer 11 calculates a horizontal distance value (F) from the side to the vertical arrangement. Therefore, the arrangement of lighting fixtures can be optimally designed in a short time.

(2) Even when different users use the lighting fixture arrangement designing apparatus 10 as described above, the lighting fixture arrangement is designed according to the same algorithm, so that the design results are the same.

(3) The determined ratio of the number of vertical arrays to the number of horizontal arrays is the closest to the aspect ratio of the rectangular area among the candidates. Therefore, if lighting fixtures are arranged on the ceiling of a room as designed, the vertical illuminance distribution and the horizontal illuminance distribution will approximate each other. Therefore, the brightness of each place in the room is made uniform.

(4) The pitch of the vertical arrangement of the lighting fixtures is calculated. When the lighting fixtures are installed on the ceiling of the room in this way, the lighting fixtures are arranged vertically at equal pitches. The same applies to the horizontal arrangement of lighting fixtures. Therefore, the brightness of each place in the room is made uniform.

(5) The pitch of the vertical arrangement of lighting fixtures is twice the vertical distance from the horizontal wall of the room to the nearest horizontal arrangement of lighting fixtures. Also, the pitch of the horizontal arrangement of the lighting fixtures is twice the horizontal distance from the vertical wall of the room to the vertical arrangement of the lighting fixtures closest thereto.

(6) Calculate the upper limit number (N) by multiplying the value (M) of the minimum required number data 35 by a predetermined constant. Then, identify combinations of two divisors whose product is each integer from M to N. Therefore, the number of combinations, that is, the number of array candidates increases. Since one sequence number is determined from many candidates, the determined sequence number is likely to be optimal.

[Second embodiment]
Next, a second embodiment will be described. In the following description, differences between the first embodiment and the second embodiment are mainly described.

In the first embodiment, the planar shape of the room constructed in the building is rectangular, and the planar shape is congruent with the rectangular area whose vertical and horizontal dimensions are represented by the dimension data 31 . In other words, the dimension data 31 represent not only the dimensions of the rectangular shape but also the dimensions of the planar shape of the room.

On the other hand, in the second embodiment, the planar shape of the room constructed within the building is not rectangular. That is, as shown in FIG. 4, a planar shape 81 of a room built in a building is an inscribed figure of a rectangular area 80 whose vertical and horizontal dimensions are determined by the dimension data 31. FIG. Here, when the outer edge of the planar shape 81 of the room touches the outer edge of the rectangular area 80 at as many points as possible and the entire planar shape 81 is inside the rectangular area 80, the planar shape 81 of the room is It is an inscribed figure of the rectangular area 80 . If the planar shape 81 of the room inscribes the rectangular area 80 , the rectangular area 80 circumscribes the planar shape 81 . In FIG. 4, the planar shape 81 of the room is trapezoidal, but the planar shape 81 of the non-rectangular room may be other than the trapezoid.

In the second embodiment, the user calculates the vertical and horizontal dimensions of a rectangular area 80 circumscribing the planar shape 81 of the room from the planar shape 81 of the room. Then, the user inputs the vertical dimension and the horizontal dimension into the computer 11 by operating the input device 13 . Then, the computer 11 obtains the vertical dimension as the vertical dimension data 32 and the horizontal dimension as the horizontal dimension data 33 (see the process (4) above). Note that the computer 11 may specify a rectangular area 80 that circumscribes the planar shape 81 of the room and calculate the vertical and horizontal dimensions of the rectangular area 80 .

In the second embodiment, the minimum required number data 35 is a rectangular area 80 circumscribing a planar shape 81 of a non-rectangular room, that is, lighting fixtures to be installed in a rectangular area 80 whose vertical and horizontal dimensions are determined by the dimension data 31. represents the minimum required number of The value of the minimum required number data 35 is calculated and input by the user. Specifically, it is as follows. That is, the user calculates the number of lighting fixtures installed in the planar shape 81 of the non-rectangular room (hereinafter referred to as the basic number) by the average illuminance method. The value of the required minimum number data 35 is obtained by dividing the basic number by the area of the room, multiplying the quotient by the area of the rectangular area, and rounding up the product. Then, the user inputs the calculated values into the computer 11 by operating the input device 13 . Then, the computer 11 obtains the calculated value as the minimum required number data 35 (see the process (1) above). Note that the computer 11 uses the basic number data stored in the storage unit 14 or the basic number data input by the input device 13 and the room area data stored in the storage unit 14 or the room area data input by the input device 13 , the dimension data 31 and the value of the minimum required number data 35 may be calculated in the same manner as the calculation by the user as described above. The value of the basic number data represents the basic number of units, and the value of the room area data represents the area of a non-rectangular room.

In the first embodiment, in the process (12) above, the computer 11 arranges the lighting fixture model 93 and the rectangular area 90 on the plane of the two-dimensional orthogonal coordinate system, and places the lighting fixture model 93 and the rectangular area 90 on the plane. Display on the display device 12 .
On the other hand, in the second embodiment, as shown in FIG. 5, the computer 11 further arranges a plane model (plan view) 95 of the room on the plane of the two-dimensional Cartesian coordinate system to form the plane model of the room. 95 , causes the display device 12 to display the luminaire model 93 and the rectangular area 90 . Here, the design data 30 includes room shape data 37 representing the planar shape of the room inscribed in the rectangular area. The computer 11 can read the room shape data 37 from the storage unit 14 and arrange the room plane model 95 so that the room plane model 95 is inscribed in the rectangular area 90 according to the room shape data 37 .

In the second embodiment, after the process (12) above, the user operates the input device 13 to designate the lighting fixture model 93 arranged outside the plane model 95 of the room. Then, the computer 11 recognizes the designation and deletes the lighting fixture model 93 designated. Then, the computer 11 causes the display device 12 to redisplay the plane model 95 of the room, the lighting model 93 (excluding the deleted lighting model 93) and the rectangular area 90 . Note that the user does not have to specify the lighting fixture model 93 to be deleted. In this case, the computer 11 compares the coordinate values of the center point of the lighting fixture model 93 and the coordinate values of the vertices of the plane model 95 of the room so that the center point of the lighting fixture model 93 is located outside the outline of the plane model 95 . It is determined whether or not there is Then, the computer 11 deletes the lighting fixture model 93 whose center point is outside the outline of the planar model 95 .

The computer 11 then counts the total number of lighting fixture models 93 that have not been deleted. Then, the computer 11 compares the total number with the basic number. As a result of the comparison, if the total number is greater than or equal to the basic number, the computer 11 terminates the process. On the other hand, if the total number is less than the basic number as a result of the comparison, the process of the computer 11 returns to the process (2) above. At this time, the computer 11 updates N and M. That is, the computer 11 adds 1 to the original N and sets the sum to the new M. The computer 11 also multiplies the new M by 1.1 and rounds up the product to the nearest whole number. Let the result be the new N. Then, the computer 11 uses the new M and N to repeat the processes after the process (2).
As a result of the comparison, if the total number exceeds the basic number, the processing of the computer 11 may be terminated, and if the total number is equal to or less than the basic number, the processing of the computer may return to the process (2) above.

In a second embodiment, an array of luminaires can be designed for installation in non-rectangular rooms.
