  Conventionally, for the purpose of improving work efficiency in the lighting design process and balancing the level of lighting designers, it automatically searches for drawings that approximate the architectural drawings that are subject to lighting design, and automatically performs lighting design for the approximate drawings. Techniques for extraction have been proposed (see, for example, Patent Document 1). In the technique described in Patent Document 1, lighting design is automatically extracted. In general residential buildings, a certain level of lighting design is possible regardless of the level of the lighting designer.

JP 2004-252530 A

  On the other hand, Patent Document 1 does not describe a technique for setting a light environment in a space where a large number of lighting fixtures such as tens to thousands of lamps are arranged. That is, when a large number of lighting fixtures are arranged in a space that is a setting target of the light environment, it is necessary to individually set the light environment for each space, and the illumination design as in the technique described in Patent Document 1 It is not easy to adopt a technology that automatically extracts

  An object of the present invention is to provide a light environment setting method and a light environment setting system in which a light environment can be set relatively easily even in a space where a plurality of lighting fixtures are arranged.

  The light environment setting method according to the present invention includes the following steps. In other words, in the first step, the target space expressed by the building information model is displayed on the screen of the monitor device so as to represent the real space that is the setting target of the light environment. In the second step, arrangement information for arranging a plurality of lighting fixtures in the target space is received. In the third step, selection information for selecting one or more target appliances from the plurality of lighting fixtures arranged in the target space is received. In a fourth step, replacement information for replacing the target device with a lighting device having a different specification is received. In the fifth step, control information assigned to the target appliance is received. When there are a plurality of the target devices, the control information is individually assigned to each of the target devices, and the replacement information can be selected as the target device to be replaced.

  The optical environment setting system according to the present invention includes an interface unit and a processing unit. The interface unit reads data of a building information model representing a real space that is a setting target of a light environment. The processing unit displays a target space expressed by the building information model on a screen of a monitor device, and selection information for selecting one or more target fixtures from a plurality of lighting fixtures arranged in the target space Is received from the input device. Furthermore, the processing unit is configured to receive replacement information for replacing the target fixture with a lighting fixture having a different specification from the input device, and to receive control information assigned to the target fixture from the input device. And the said process part can select the lighting fixture which the said control information is individually allocated to each of the said object instrument, and the said replacement information replaces, when the said object instrument is plurality.

  According to the structure of this invention, even if it is the space where a several lighting fixture is arrange | positioned, it has the advantage that the setting of a light environment can be performed comparatively easily.

  Below, the technique which sets the light environment implement | achieved by the lighting fixture arrange | positioned in the building of real space by using the building information model expressing a building in the virtual space which a computer constructs is demonstrated. A building information model that expresses a building in a virtual space is known as BIM (Building Information Modeling). Hereinafter, the data of the building information model that expresses the building in the virtual space corresponding to the real space is referred to as “BIM data”.

  BIM is a technology for expressing a building in a virtual space constructed using a computer. BIM data is not only data representing the shape and dimensions of buildings such as 3D CAD (Computer Aided Design), but also data on individual components that make up buildings, and data on equipment arranged in buildings. Many types of building data are integrated. That is, the BIM data represents the total of various data related to the building.

  The building may be not only a building such as an office building but also a hospital, a commercial facility, a stadium, a museum, a museum, a bridge, a road, a tower, and the like. For example, a general hospital or a commercial facility may have 10,000 or more lighting fixtures. If it is a hospital, warm-colored lighting in a waiting room or the like will alleviate tension. For commercial facilities, controlling lighting fixtures according to purposes such as entrance lighting, passage lighting, and display lighting may contribute to an increase in the amount of customers and sales.

  The target space that defines the light environment in a building is usually selected from the internal space of the building, but may be an outer wall of the building, land around the building, or the like. That is, the target space may be either a light environment of an internal space or an external space of a building. In the following description, the target space is assumed to be the inside of a room used for an office or the like in a building. In this type of room, a plurality of lighting fixtures are often arranged. The light environment described below is a light environment formed by a lighting fixture included in the BIM data, and changes in the light environment due to sunlight or the like are not considered. Although it is possible to include the influence of sunlight or the like in the formation of the light environment, in the following configuration example, it is assumed that components other than the luminous flux from the lighting fixture do not change.

  The work of setting the light environment is performed in a virtual space constructed by a computer so as to correspond to the real space. Therefore, a program for executing the light environment setting method described below on a computer is used. By executing this program, the computer realizes a configuration excluding the input device 21 and the monitor device 22 in the optical environment setting system 10 having the configuration shown in FIG.

  The light environment setting system 10 shown in FIG. 1 includes a first interface unit 11 that inputs and outputs BIM data. The light environment setting system 10 includes a second interface unit 12 that receives information from the input device 21 and a third interface unit 13 that outputs information to the monitor device 22. Hereinafter, the “interface unit” is abbreviated as “I / F”. The second I / F 12 and the third I / F 13 may be physically shared by one device. Further, the first I / F 11, the second I / F 12, and the third I / F 13 may be physically configured by one device. The light environment setting system 10 includes a processing unit 14 that receives information from the input device 21 through the second I / F and outputs information to the monitor device 22 through the third I / F. Further, the processing unit 14 writes and reads information to and from the storage device 15.

  The processing unit 14 includes an MPU (Micro-Processing Unit: microprocessor) and a work semiconductor memory as main hardware elements. The storage device 15 includes an external storage device such as a hard disk device and a semiconductor memory. The BIM data describing the building is read into the storage device 15 through the first I / F 11. Further, the information set by the light environment setting system 10 can be taken out through the first I / F 11.

  The input device 21 is a device that gives an instruction from the user to the light environment setting system 10 and is selected from a keyboard, a pointing device, a touch panel, and the like. The pointing device is selected from a mouse, a trackpad, a joystick, and the like. The monitor device 22 is selected from a liquid crystal display, an organic EL display (OELD: Organic ElectroLuminescence Display), a CRT display (CRT: Cathode Ray Tube), and the like.

  The input device 21 and the monitor device 22 can also be realized by a device selected from a smartphone, a tablet terminal, a personal computer, and the like. In this case, it is desirable to execute an application program (so-called “application”) in order to cause a device selected from a smartphone, a tablet terminal, a personal computer, or the like to function as the input device 21 and the monitor device 22.

  The computer that realizes the optical environment setting system 10 is not limited to one computer, and may be a plurality of computers that perform parallel processing in cooperation with each other. Further, the computer may be a combination of a server and a terminal device (client) that communicate via an electric communication line such as the Internet. When the light environment setting system 10 includes a server, the server is responsible for the main functions described above, and the terminal device may only function as the input device 21 and the monitor device 22. That is, the terminal device may be a thin client. When the light environment setting system 10 is constructed by the server and the terminal device, the program for designing the light environment is executed by the server, and the user can create the BIM data using the server program using the terminal device. Is possible. The server may allow the user to use the program in the form of SaaS (Software as a Service). The server is not limited to a single computer, and may be configured by a plurality of computers operating in cooperation with each other, or may be in the form of cloud computing.

  The light environment setting system 10 is used to set conditions such as the arrangement, specifications, and lighting state of lighting fixtures so that the lighting environment of the target space is realized by the lighting fixtures. The lighting state is not limited to the two types of lighting and extinguishing states. When using a lighting fixture capable of adjusting the light output, the dimming state and when using the lighting fixture capable of adjusting the emission color. Includes toning status. When a plurality of lighting fixtures are arranged in the target space, a plurality of lighting fixtures having a dimming function capable of adjusting the light output and a lighting fixture having a toning function capable of adjusting the emission color are provided. It may be included in the lighting fixture. Moreover, the lighting fixture may have not only one function of light control and color control but also both functions.

  The light environment setting system 10 includes a simulator 16 that performs in a virtual space that simulates a light environment according to conditions such as the arrangement, specifications, and lighting state of one or more lighting fixtures. The simulator 16 can perform a static operation for performing a simulation according to a condition after the condition including the lighting state is determined, and a dynamic operation for performing a simulation immediately after changing the lighting state. In the dynamic operation, when at least one of the light output and the emission color is changed, it is reflected in the simulation result of the light environment immediately after the change. In other words, the user can change at least one of the light output and the emission color while visually checking the result of the simulation.

  Hereinafter, among the plurality of lighting fixtures that determine the light environment of the target space when the simulator 16 performs the simulation of the light environment of the target space, the lighting fixture in which the lighting state is instructed is referred to as “target fixture”. The target fixture may include a lighting fixture that can be instructed to be turned on and off during a period in which the other lighting fixtures are turned on. The target appliance may be a lighting fixture in which a lighting state is instructed for at least one of the light output and the emission color among the plurality of lighting fixtures that define the light environment of the target space. The conditions used by the simulator 16 for the simulation are stored in the storage device 15 as control information so as to be applicable to a lighting fixture arranged in the real space. Therefore, after the building is constructed, it is possible to read the control information from the storage device 15 through the first I / F 11 and apply the control information to the lighting control system in the real space.

  Below, the technique which allocates control information to an object instrument using the optical environment setting system 10 mentioned above is demonstrated. Here, it is assumed that the building environment BIM data read by the light environment setting system 10 through the first I / F 11 is stored in the storage device 15. Since BIM data includes various data relating to buildings, it is desirable to narrow down to data necessary for setting the light environment.

  When BIM data for the entire building is stored in the storage device 15, the user operates the input device 21 with respect to the building image displayed on the monitor device 22, so that the image of the target space is displayed. It is desirable to narrow down. In addition, when the BIM data of the target space can be automatically extracted from the BIM data of the entire building, or when the BIM data of the target space is extracted in advance, only the BIM data of the target space is stored in the storage device 15. That's fine.

  Here, an example in which the user narrows down the image of the target space by operating the input device 21 will be described. That is, it is assumed that BIM data of the entire building is stored in the storage device 15. Now, an office building having a plurality of floors is assumed as an example of a building. The structure of this type of building is divided into the overall structure of the building, the structure of the floor, the structure of the room, etc., and the structure is subdivided in this order. BIM data is generally hierarchized so as to correspond to the subdivision of the structure of a building. That is, the BIM data of the hierarchy corresponding to the floor is linked to the lower hierarchy of the BIM data corresponding to the entire building, and the BIM data of the hierarchy corresponding to the room is linked to the lower hierarchy of the BIM data of the hierarchy corresponding to the floor. .

  The hierarchy corresponding to the floor has a plurality of sets of BIM data corresponding to each of the plurality of floors, and each of the plurality of floors has a room 40 (FIGS. 2 and 2) provided in each of the plurality of floors as a lower hierarchy. 3 and FIG. 4). The BIM data corresponding to the room 40 may be one set on one floor, but may be a plurality of sets. Here, a set of BIM data corresponding to the room 40 means a group of data necessary to represent the room 40 in a virtual space constructed by a computer.

  The light environment setting system 10 is configured to receive designation information from the input device 21 in a state where the entire building is displayed on the monitor screen when the user designates the room 40 which is the target space in this configuration example. Is done. Since the BIM data of the building is hierarchized as described above, designation information for designating the floor is received in a state where the entire building is displayed on the monitor screen. When the floor is designated, the light environment setting system 10 is configured to receive designation information for designating the room 40 that is the target space from the input device 21 in a state where the designated floor is displayed on the monitor screen. .

  Since BIM data includes three-dimensional information of buildings, a three-dimensional image or a two-dimensional image is displayed on the monitor screen. For example, when the light environment setting system 10 displays the entire building on the monitor screen, it is represented by a three-dimensional image corresponding to a perspective view of the building, and when the floor is displayed on the monitor screen, the floor plan view. Can be represented by a two-dimensional image corresponding to. Further, when the room 40 is displayed on the monitor screen, a two-dimensional image corresponding to a ceiling plan view of the room 40 as shown in FIG. 2, and a three-dimensional view corresponding to a perspective view viewed from the inside of the room 40 as shown in FIG. An image, a three-dimensional image corresponding to a perspective view seen from the outside of the room 40 as shown in FIG. 4, and the like can be selected. The three-dimensional image shown in FIG. 4 is a state in which the ceiling and some walls are seen through from the outside of the room 40. The image of FIG.2, FIG.3, FIG.4 shows the lighting fixture 31 attached to a ceiling.

  Here, it is desirable that the light environment setting system 10 has a function of selecting the types of images to be displayed on the monitor screen from a plurality of predetermined types. For example, as shown in FIG. 2 and the like, the screen of the monitor device 22 is divided into a work area D10 for displaying an image of a building and a selection area D11 in which a plurality of predetermined image options are arranged. It is desirable that In the selection area D11, a plurality of names corresponding to the hierarchy of the structure of the building are displayed, and options representing the types of images to be displayed on the monitor screen are displayed for each of the plurality of names. That is, the options are represented by letters. Therefore, the user can display the target space suitable for work on the monitor screen by selecting the target space to be displayed on the monitor screen by name and performing an operation of selecting an option of the type of image representing the target space. it can. As described above, since a plurality of types of image options are prepared in the light environment setting system 10, even a user unfamiliar with the operation of the light environment setting system 10 can easily select an appropriate image from the selection range. be able to.

  By the way, when displaying a three-dimensional image, even if the target space is the same, if the viewpoint changes, the information included in the three-dimensional image changes. Therefore, when the target space is displayed as a three-dimensional image, it is desirable that a plurality of types of appropriate viewpoint options are prepared in advance. In this case, the user can display a three-dimensional image of the room 40 on the monitor screen from a plurality of appropriate viewpoints. On the other hand, a user who is skilled in the design of the light environment may display a three-dimensional image of the room 40 on the monitor screen from a viewpoint different from the viewpoint prepared in the light environment setting system 10. In order to cope with such a case, it is desirable that the light environment setting system 10 also has a function capable of arbitrarily changing the position of the viewpoint.

  In the configuration example described above, an image to be displayed in the work area D10 of the monitor screen is selected by the option displayed in the selection area D11 of the monitor screen, but the work area D10 is utilized using the hierarchical structure of the BIM data. An image to be displayed may be selected. For example, in a state where a three-dimensional image representing the entire building is displayed on the monitor screen based on the BIM data, the user is allowed to specify a floor, and a two-dimensional image corresponding to a floor plan is displayed on the monitor screen. The user can designate the room 40. In this case, the selection region D11 is not necessarily provided.

  When the user knows the name of the target space for designing the light environment, the target space can be specified more quickly by specifying the target space from the options of the selection area D11 than when specifying the target space from the image. Is possible. On the other hand, when the target space is designated from the image, the user can easily recognize the position of the target space in the building. Therefore, it is desirable that the light environment setting system 10 is configured so that the target space can be designated by either method.

  By the way, information representing the lighting fixture 31 is hierarchized in two stages. The information on the upper hierarchy is the name given to the lighting fixture 31, the shape of the lighting fixture 31, the position of the lighting fixture 31, and information that determines the arrangement of the lighting fixture 31. On the other hand, the information on the lower layer includes light output (light flux), light emission color, power consumption, light distribution, material, and the like of the lighting fixture 31 and is information on specifications as a light source of the lighting fixture 31. In an application program that creates BIM data, information in an upper layer is sometimes referred to as an “instance”, and information in a lower layer is sometimes referred to as a “type”.

  The lighting fixture 31 has a specification having only a function of turning on and off, a specification having a dimming function for adjusting the light output according to the control information, and an adjustment for adjusting the emission color in addition to the adjustment of the light output by the control information. Some specifications have color functions. Moreover, as the lighting fixture 31, the specification which can adjust light distribution by control information is also known. For example, in the lighting fixture 31 which performs spot illumination, the structure which receives control information and adjusts light distribution is known.

  Here, the case where the lighting fixture 31 which has a light control function and a color control function is arrange | positioned in object space is demonstrated. Although there is a configuration in which the hue is changed in a wide range depending on the lighting fixture 31, the lighting fixture 31 configured to change the emission color on a black body locus is assumed here. This kind of lighting fixture 31 is comprised so that color temperature may be variable in the range from 2500K to 6000K, for example. In addition, the numerical value of the color temperature described here is an example.

  The technology described below is applicable even to a lighting fixture 31 that does not have one of a light control function and a color control function, or a light fixture 31 that does not have either a light control function or a color control function. Is possible. Moreover, the some lighting fixture 31 is selected from the lighting fixture 31 which has at least one of a light control function and a toning function, and the lighting fixture 31 which has neither a light control function nor a toning function. What is necessary is just to include one or more types. For example, some of the plurality of lighting fixtures 31 may not have both the light control function and the color adjustment function, and the rest of the plurality of lighting fixtures 31 may have only the light control function. Alternatively, some of the plurality of lighting fixtures 31 may have both a dimming function and a toning function, and the remainder of the plurality of lighting fixtures 31 may have only a dimming function.

  If the information representing the lighting fixture 31 is hierarchized as described above, when the lighting fixture 31 is placed in the room 40, which is the target space, the information is replicated using information of a higher hierarchy that determines the placement of the lighting fixture 31. Can be done. Note that the position of the luminaire 31 in the upper hierarchy information is automatically determined by arranging the luminaire 31 in the target space. When the lighting fixture 31 is placed on the ceiling of the room 40, which is the target space, a two-dimensional image corresponding to the ceiling plan is displayed on the monitor screen as shown in FIG. Further, when the user confirms the arrangement of the lighting fixtures 31 as viewed from the inside of the room 40, a three-dimensional image as shown in FIG. 3 can be displayed on the monitor screen.

  The processing unit 14 displays the two-dimensional image as illustrated in FIG. 2 or the three-dimensional image as illustrated in FIG. The initial information for determining is received from the input device 21. The information of the lower hierarchy in the information representing the lighting fixture 31 represents the specification of the lighting fixture 31 as described above. In the initial information, the lower layer information is set to the same content for all the lighting fixtures 31 arranged on the ceiling of the room 40. That is, a specification is defined for one of the lighting fixtures 31 arranged on the ceiling of the room 40, and information on a lower hierarchy of the lighting fixture 31 is copied to all the lighting fixtures 31 arranged on the ceiling of the room 40. .

  When the arrangement of the plurality of lighting fixtures 31 is determined as shown in FIG. 2, individual identification information is given to each of the plurality of lighting fixtures 31. The identification information does not need to be different for all the luminaires 31 as in the case of the serial number, and may be different in the range of the luminaires 31 used for setting the light environment. For example, the identification information may be uniquely set in the range of the building, may be set uniquely in the range of the floor, or may be uniquely set in the range of the room 40.

  Thus, unique identification information is given to each of the plurality of lighting fixtures 31. The identification information can be given to each of the plurality of lighting fixtures 31 by the user operating the input device 21. However, if the user gives identification information to the lighting fixtures 31, there is a possibility that the same identification information is given to two or more lighting fixtures 31 in a duplicated manner, and that the giving of identification information to the lighting fixtures 31 may be forgotten. There is. Therefore, it is desirable that the provision of identification information for the plurality of lighting fixtures 31 is automated. Alternatively, after the user instructs from the input device 21 the initial value of the identification information to be given to the luminaire 31 and the rule for giving the identification information, the identification information is given to the plurality of luminaires 31 automatically. May be. The rule for giving identification information means, for example, the order in which the identification information is given to the lighting fixture 31.

  By the way, when the some lighting fixture 31 is arrange | positioned in object space, instead of controlling the lighting state of all the lighting fixtures 31 collectively, one selected from the lighting fixtures 31 arrange | positioned in object space. There may be a case where only the above-described lighting fixture 31 is a control target. That is, only the target instrument 30 involved in the setting of the light environment may be selected as a control target among the plurality of lighting apparatuses 31 arranged in the target space. Further, when at least one of the light output and the emission color of the target device 30 can be controlled, at least one of the light output and the emission color may be adjusted according to the situation of the room 40. The situation of the room 40 here is the number of people present in the room 40, the position of the person present in the room 40, the time zone, the season, the room temperature, the intensity of outside light, and the like. Such a situation of the room 40 is hereinafter referred to as a “scene”.

  When the arrangement of the plurality of lighting fixtures 31 with respect to the ceiling of the room 40, the specifications of the plurality of lighting fixtures 31, and the identification information of each of the plurality of lighting fixtures 31 are determined, the target appliance 30 to be controlled can be selected according to the scene. It becomes possible. When selecting the target appliance 30 according to the scene, it is possible to use the ceiling plan shown in FIG. 2, but in the ceiling plan, the fixtures arranged in the room 40 and the lighting fixture 31 are used. The positional relationship is unknown. Therefore, when selecting the target appliance 30 according to the scene, it is desirable to display a three-dimensional image overlooking the room 40 through the ceiling and some walls as shown in FIG. In this display example, the luminaire 31 is shown in a diagram.

  In this screen, if the user operates the input device 21 and inputs selection information for designating the target instrument 30 to the processing unit 14, the target instrument 30 can be determined. For example, when the pointing device such as a mouse is the input device 21, if the user performs a click operation by placing the cursor on the range of the lighting fixture 31 selected as the target fixture 30, the lighting fixture 31 is set as the target fixture 30. Selection information to be given is given to the processing unit 14. Here, in the image of the monitor screen, the lighting device 31 selected as the target device 30 is subjected to a change in the color of the line, a filling of a range surrounded by the line, and the like, and the target device 30 is changed according to the change in the display state. It is distinguished from the lighting fixture 31 which is not.

  When selecting a plurality of lighting fixtures 31 as the target fixture 30, the user designates a rectangular area including the target fixture 30 with a pointing device, and excludes the lighting fixtures 31 that are not the target fixture 30 in the rectangular area. May be performed. For specifying the rectangular area, the user may perform an operation of starting dragging at one end of the diagonal line and ending dragging at the other end of the diagonal line, for example. The display state of the luminaire 31 included in the designated rectangular area once changes, but is excluded from the target appliance 30 by, for example, performing an individual click while pressing the “Ctrl” key.

  The operation using the pointing device for selecting the target instrument 30 is an example, and a configuration in which the target instrument 30 is selected by operating an input device such as a keyboard may be employed. For example, each time the cursor key or the “Tab” key is operated, the lighting fixtures 31 are sequentially selected, and when the selected lighting fixture 31 is selected as the target fixture 30, the “Enter” key is pressed while holding down the “Ctrl” key. The operation of pressing can be performed. Or you may select the object instrument 30 by operating combining a keyboard and a pointing device.

  As described above, the light environment setting system 10 receives selection information from the input device 21 and selects the target device 30 when a predetermined operation is performed on the input device 21 while waiting for the selection of the target device 30. To do. Information on the selected target device 30 is stored in the storage device 15. When information on the target instrument 30 is stored in the storage device 15, a screen as shown in FIG. 5 can be displayed. The screen shown in FIG. 5 is displayed as a window W11 when the user operates the input device 21 in a state where an image as shown in FIG. 4 is displayed on the monitor screen.

  The window W11 shown in FIG. 5 includes a field F11 in which the identification information of the target appliance 30 is displayed side by side, a button B11 labeled “scene design”, and a button B12 labeled “rendering”. The identification information of the luminaire 31 is expressed in the form of “Light-**” in FIG. “**” is a numerical value, and if the numerical value is different, it represents different identification information. The target appliances 30 displayed in the field F11 are treated as one group because the lighting state is instructed collectively. Therefore, group information is set separately from the identification information in the target instrument 30 displayed in the field F11. The group information can be input by the user from the input device 21, but the light environment setting system 10 may be configured to automatically set the group information. If group information is set in the target appliance 30, one or a plurality of target appliances 30 can be controlled as a group of lighting fixtures 31. Therefore, it becomes possible to set control information for a group of lighting fixtures 31 so as to suit a specific situation.

  When the button B11 labeled “scene design” is operated, the lighting fixture 31 having the identification information displayed in the field F11 is associated as the target fixture 30 that is controlled corresponding to one scene. A plurality of lighting fixtures 31 having identification information displayed in the field F11 can be turned on and off collectively as the target fixture 30 controlled in one scene. At this stage, the lighting fixtures 31 to be collectively controlled are merely associated as the target appliances 30, and the lighting states of the plurality of target appliances 30 cannot be individually controlled. Moreover, since the lighting fixtures 31 are arranged in the room 40 by copying, the specifications of all the lighting fixtures 31 are equal.

  When the lighting fixtures 31 having different specifications are adopted for some of the plurality of lighting fixtures 31 arranged in the room 40, the lighting fixtures 31 having different specifications are arranged in the next stage. For example, most of the lighting fixtures 31 arranged in the room 40 have a specification that can be turned on and off, and only a part of the lighting fixtures 31 arranged in the room 40 has at least one of light output and emission color. When the specification is variable, the lighting fixture 31 having the latter specification is arranged in the next stage. This is a case where a large number of lighting fixtures 31 are arranged in the room 40, and when the specifications of only a small number of lighting fixtures 31 are different, a small number of illuminations having different specifications are arranged after the lighting fixtures 31 of the same specification are arranged. This is because the work efficiency is better when the instrument 31 is arranged.

  Here, when the button B11 is operated, the specifications of the plurality of target devices 30 can be individually changed, and the lighting states of the plurality of target devices 30 can be individually adjusted. That is, when the button B11 is operated, it is possible to individually change the specification and specify the lighting state for each of the target instruments 30 displayed in the field F11 shown in FIG.

  For example, in order to replace a part of the target fixture 30 shown in the field F11 with a lighting fixture 31 having a different specification, information on the selection of the lighting fixture 31 to be replaced and the specification of the replacement lighting fixture 31 is obtained from the light environment setting system 10. Need to give to. Such information is hereinafter referred to as replacement information. That is, the user operates the button B11 in a state where the target instrument 30 is displayed in the field F11 illustrated in FIG. 5 and further inputs replacement information from the input device 21.

  Specifically, after the operation of the button B11, the user selects the lighting fixture 31 whose specification is to be changed in a state where an image as shown in FIG. 4 is displayed on the monitor screen. Here, it is assumed that the three lighting fixtures 31 arranged in a line at the left end in FIG. 4 are replaced with the lighting fixtures 31 capable of adjusting the light output and the emission color. That is, when the user operates the input device 21 and selects three lighting fixtures 31 whose specifications are to be changed, the light environment setting system 10 displays the options of the lighting fixtures 31 that are candidates for replacement on the monitor screen. The user is made to select the lighting fixture 31.

  The choices of the lighting fixtures 31 displayed on the monitor screen include a plurality of items of a large classification such as “normal”, “light control”, “color adjustment”, and “light distribution”, Specific specifications are displayed as options below each item. For example, when the main item is “dimming”, specific choices for the lighting fixture 31 depending on whether the dimming is stepped dimming or continuous dimming, the type of light source, power consumption, etc. Is displayed on the monitor screen. In order to acquire information on the lighting fixture 31 displayed on the monitor screen by the light environment setting system 10, communication is performed through the first I / F 11 with a database in which information on the lighting fixture 31 with various specifications is registered. Just do it. This type of database is preferably provided in the server. In the light environment setting system 10, it is desirable that specific information of the lighting fixture 31 is stored in the storage device 15 in advance.

  The lighting fixture 31 shown in the field F11 with the button B11 operated is the target fixture 30. That is, when at least a part of the luminaire 31 shown in the field F <b> 11 is replaced with a luminaire 31 having a different specification, the replaced luminaire 31 is also the target appliance 30. When the replacement lighting fixture 31 has a specification in which at least one of light output and emission color is variable, when the replacement lighting fixture 31 is selected, a window W12 shown in FIG. 6 is displayed on the monitor screen. The In this window W12, a light adjustment slider SL1 that enables adjustment of the light output of the selected lighting fixture 31, and a color adjustment slider SL2 that enables adjustment of the emission color of the selected lighting fixture 31; Is displayed.

  The window W12 is provided with two radio buttons RB1 and RB2 for selecting whether or not to perform “real-time dimming”. When the “ON” radio button RB1 is selected, the simulation result of the light environment according to the positions of the sliders SL1 and SL2 is immediately displayed on the monitor screen. That is, when the “ON” radio button RB1 is selected, a three-dimensional image inside the room 40 is displayed on the monitor screen, and the light output and emission color corresponding to the positions of the sliders SL1 and SL2 are displayed on the monitor screen. It is reflected in the displayed three-dimensional image.

  On the other hand, when the “OFF” radio button RB2 is selected, a three-dimensional image similar to that in FIG. 4 is displayed in the work area D10 of the monitor screen. In this state, the luminance information of the selected lighting fixture 31 changes according to the position of the slider SL1, and the color information of the selected lighting fixture 31 changes according to the position of the slider SL2. The result of the simulation of the light environment according to the positions of the sliders SL1 and SL2 can be confirmed by operating the button B21 labeled “reproduction”. That is, when the button B21 is operated, a three-dimensional image of the room 40 viewed from the inside is displayed on the monitor screen in a state where the light output and the emission color corresponding to the positions of the sliders SL1 and SL2 are reflected. That is, when the button B21 is operated, a simulation is performed by the simulator 16, and the result is displayed on the monitor screen.

  A three-dimensional image seen through the ceiling and some walls as shown in FIG. 4 or a three-dimensional image seen from the inside of the room 40 as shown in FIG. 3 is displayed separately from the window W12. The user determines the positions of the sliders SL1 and SL2 according to the scene, confirms the result of the simulation, and then operates the button B22 labeled “Close” to store the light output and the emission color corresponding to the scene. Registered in the device 15. That is, it is possible to set the lighting state of each lighting fixture 31 in one scene. The set lighting state data is handled as part of the BIM data. A name can be given to the scene, and the target device 30 and the lighting state data of the target device 30 set as described above are stored in the storage device 15 in a state in which the name of the scene is associated. Stored. Therefore, the lighting state data of the lighting fixture 31 can be read from the storage device 15 by the name of the scene. That is, after the scene information is registered in the storage device 15, by designating the name, information corresponding to the name can be given to the simulator 16, and the light environment of the room 40 can be simulated. It is.

  If the three-dimensional image displayed on the monitor screen by the simulator 16 accurately reproduces the light environment in the real space, the information related to the light fixture 31 set by the light environment setting system 10 is applied to the light fixture in the real space. Can be fitted. Therefore, the result of the simulation in the simulator 16 is reproduced in the real space by matching the specification and the lighting state of the lighting fixture in the real space with the specification and lighting state of the lighting fixture 31 determined by the light environment setting system 10. Is possible.

  By the way, in order to control lighting fixtures corresponding to scenes in real space, it is necessary to construct a lighting control system that links the operations of a plurality of lighting fixtures. Therefore, a technique for controlling lighting states of a plurality of lighting fixtures by communication is adopted. Although this type of technology is well known, it will not be described in detail, but the lighting control system uses a centralized control network in which a centralized control device polls a plurality of terminals, and distributed control in which terminals communicate with each other. Technology using a type network is known.

  The information stored in the storage device 15 of the light environment setting system 10 as described above is in the same format as the control information of the lighting control system so that it can be used as the control information of the lighting control system in real space. To be created. Therefore, after the lighting control system is constructed in the real space, only the information stored in the storage device 15 is given to the lighting control system, and the simulation result corresponding to the scene is reflected in the control of the lighting fixture in the real space. It is possible.

  As described above, since it is possible to perform simulation by adding information on the lighting fixture 31 to BIM data, it is possible to perform accurate simulation using detailed information regarding the target space. Moreover, since the light environment simulation is performed by the light environment setting system 10, it is possible to change the specifications and control information of the lighting fixture 31 in various ways and confirm the influence of the specifications and control information of the lighting fixture 31 on the light environment. It is. As a result, it is possible for an expert who has a lot of on-site experience to reduce the possibility of on-site adjustment and erroneous setting by checking the designed light environment before construction. In addition, for non-experts with little on-site experience, various conditions regarding the design of the light environment can be tried, and as a result, the amount of experience can be increased without accompanying on-site experience.

  In addition, since the light environment setting system 10 performs simulation using BIM data, the light environment in the real space can be accurately reproduced in the virtual space, and the control information used for the simulation can be reproduced in the real space. It is possible to output as control information to be used. Therefore, by applying the control information used for the simulation to the illumination control system constructed in the real space, the simulation result can be easily reproduced in the real space. That is, it is possible to greatly reduce the on-site adjustment work, leading to a shortened construction period of the building.

  As described above, in this configuration example, as shown in FIG. 7, the light environment is set according to the following procedure. The processing unit 14 of the light environment setting system 10 displays an image of the target space such as the room 40 on the screen of the monitor device 22 based on the BIM data (S1), and the lighting fixture 31 arranged in the target space. It waits for the arrangement information to be input from the input device 21 (S2). In step S2, one or more lighting fixtures 31 are arranged in the target space. When a plurality of lighting fixtures 31 are arranged in the target space in step S2, the initial information regarding the specifications of the lighting fixtures 31 is duplicated. That is, only a plurality of lighting fixtures 31 having the same specifications are arranged in the target space. Note that either the step in which the processing unit 14 receives the arrangement information from the input device 21 or the step in which the processing unit 14 receives the initial information from the input device 21 may be first. The display content of the monitor screen may be configured so that the two steps can be performed together.

  After the plurality of lighting fixtures 31 are arranged in the target space in step S2, the processing unit 14 of the light environment setting system 10 selects information for selecting the target fixture 30 that is the lighting fixture 31 to be controlled from the input device 21. Is received (S3). In the configuration example described above, the target instrument 30 is listed in the field F11 of the window W11 illustrated in FIG. Here, when the button B11 is operated for scene setting, the processing unit 14 is in a state of accepting replacement information for replacing the target fixture 30 with a lighting fixture 31 having a different specification from the input device 21 (S4).

  If it is not necessary to replace the target fixture 30 with a lighting fixture 31 having a different specification, the process of giving replacement information from the input device 21 to the processing unit 14 may be omitted. When the target instrument 30 is selected, the processing unit 14 can receive control information set in the target instrument 30 (S5). When there are a plurality of target instruments 30 in the field F11, it is possible to individually set control information for each of the plurality of target instruments 30. That is, the light environment setting system 10 waits for an instruction from the input device 21 when the button B11 is operated to change the specification and set the control information for the target instrument 30. When neither the specification change nor the control information setting is performed, the instruction waiting state ends by closing the window W11. In addition, it is possible to set control information in a state where a plurality of target appliances 30 are selected. In this case, the control contents of the selected target appliances 30 are the same.

  When at least a part of the target fixture 30 is replaced with a lighting fixture 31 having a dimming function and a toning function, the lighting fixture 31 having the dimming function and the toning function is selected when setting a scene. Then, the window W12 is displayed on the monitor screen. The processing unit 14 of the light environment setting system 10 enables adjustment of the light output of the lighting fixture 31 by operating the slider SL1 while the window W12 is displayed on the monitor screen, and lighting by operating the slider SL2. The emission color of the instrument 31 can be adjusted (S5). In other words, in step S <b> 5, the processing unit 14 receives, from the input device 21, control information that determines the light output and the emission color when the target device 30 is a lighting device 31 having a dimming function and a toning function.

  The light environment corresponding to the control information instructed by the user through the scene setting operation can be displayed on the monitor screen by simulation with the simulator 16 (S6). When the light environment of the target space is displayed on the monitor screen, the operation in which the change of the control information is immediately reflected in the image, and the control when the user instructs the display of the result from the input device 21 after changing the control information. An operation in which information is reflected in an image can be selected.

  In a state where the light environment of the target space in which the control information is reflected is displayed on the monitor screen, the light environment setting system 10 can accept registration of control information from the input device 21. If the user is satisfied with the light environment displayed on the monitor screen, the user operates the input device 21 to store the control information in the storage device 15 (S7). The control information stored in the storage device 15 is described in a format applicable to a lighting control system used in real space. Therefore, the light environment confirmed by the simulation in the light environment setting system 10 can be applied to the real space lighting control system with almost no correction. That is, since the light environment setting system 10 reflects the result of the accurate simulation by using the BIM data in the control of the lighting fixture 31 in the real space, it becomes possible to reduce the amount of work in the field. This will shorten the time for installing the lighting control system in the building.

  In the configuration example described above, it is assumed that the lighting fixture 31 is not described in the BIM data read by the light environment setting system 10, but when the arrangement of the lighting fixture 31 is described in the BIM data, Step S2 in FIG. 7 can be omitted. However, even when the arrangement of the lighting fixture 31 is described in the BIM data, when the lighting fixture 31 having a different specification from the lighting fixture 31 described in the BIM data is arranged in the target space, step S2 is performed. You may wait for the input from the input device 21, without omitting.

  The light environment setting method described above includes the following steps. That is, in the first step, the target space (for example, the room 40) expressed by the building information model so as to represent the real space that is the setting target of the light environment is displayed on the screen of the monitor device 22 (S1). In the second step, arrangement information for arranging a plurality of lighting fixtures 31 in the target space is received (S2). In the third step, selection information for selecting one or more target appliances 30 from a plurality of lighting fixtures 31 arranged in the target space is received (S3). In the fourth step, replacement information for replacing the target device 30 with a lighting device 31 having a different specification is received (S4). In the fifth step, control information assigned to the target appliance 30 is received (S5). When there are a plurality of target instruments 30, control information is individually assigned to each target instrument 30, and the replacement instrument can be selected as the target instrument 30 to be replaced.

  The optical environment setting system 10 described above includes an interface unit 11 and a processing unit 14. The interface unit 11 reads building information model data (BIM data) representing a real space which is a setting target of the light environment. The processing unit 14 displays the target space (for example, the room 40) expressed in the building information model on the screen of the monitor device, and displays one or more target fixtures 30 from the plurality of lighting fixtures 31 arranged in the target space. It has a function of accepting selection information for selection from the input device 21. The processing unit 14 is configured to receive replacement information for replacing the target fixture 30 with a lighting fixture 31 having a different specification from the input device 21 and to receive control information assigned to the target fixture 30 from the input device 21. . Then, when there are a plurality of target devices 30, the processing unit 14 can select the target device 30 to which control information is individually assigned to each target device 30 and the replacement information is replaced.

  According to this technique, it is possible to select only the lighting fixture 31 necessary for setting a desired light environment among the plurality of lighting fixtures 31 arranged in the target space as the target fixture 30. In addition, since the target instrument 30 can have a different specification from the other illumination instruments 31, the light environment can be set by changing the specifications of the illumination instrument 31. When a plurality of target instruments 30 are selected, control information can be individually assigned to each of the target instruments 30, so that the target instrument 30 can control the light environment according to the state of the target space. In addition, when a plurality of target devices 30 are selected, the target device 30 to be replaced from the selected target devices 30 can be selected, and therefore it is possible to select the target device 30 according to the state of the target space. .

  In short, by adopting the above-described light environment setting method, the degree of freedom in setting the light environment of the target space is increased, and the change in the specification of the lighting fixture 31 for obtaining the desired light environment is reduced and the cost is reduced. The increase can be suppressed. Therefore, even in a space in which a plurality of lighting fixtures 31 are arranged, a comparison is made by selecting some lighting fixtures 31 as target appliances 30 to be controlled and changing specifications as necessary. It is possible to easily obtain a desired light environment.

  The light environment setting method may include a step of receiving initial information for assigning the lighting fixtures 31 of the same specification as the plurality of lighting fixtures 31 before the step of receiving the selection information (S2).

  That is, since the same specification is assigned to a plurality of lighting fixtures 31 arranged in the target space before the target fixture 30 is selected, the work of assigning the specification to the lighting fixture 31 first is simply a duplication. Become work. This technique is particularly effective when a large number of lighting fixtures 31 are arranged in the target space, and the user simply designates one specification for the plurality of lighting fixtures 31, and the specification for each of the plurality of lighting fixtures 31. Since it is not necessary to specify the above, the amount of work can be reduced.

  The light environment setting method preferably includes the step of storing the control information assigned to the target fixture 30 in the storage device 15 in a format applied to the lighting fixture 31 in the real space.

  That is, according to this technology, the control information stored in the storage device 15 can be used for controlling the lighting fixture 31 in the real space. It is possible to reduce the amount of work.

  It is desirable that the lighting fixture 31 replaced with the target fixture 30 is configured such that the light output, the emission color, and the light distribution alone or in combination are controlled by the control information.

  In other words, since at least one of light output, emission color, and light distribution can be controlled for the lighting fixture 31, it is possible to design a light environment that cannot be realized simply by turning the lighting fixture 31 on and off. is there. For example, when setting up a light environment such as a commercial facility, it is possible to increase the number of customers and increase the sales volume by controlling at least one of the light output, emission color, and light distribution. It is.

  The light environment setting method preferably includes a step of displaying a simulation result of the light environment in the target space obtained when the control information is applied to the target instrument 30 on the screen of the monitor device 22.

  According to this technique, since the simulation result of the light environment in the virtual space can be confirmed on the screen of the monitor device 22, the set light environment can be immediately confirmed visually. Therefore, it is possible to try the light environment under various conditions without working in the real space, and the user can gain experience regarding the light environment in a relatively short period of time.

  The light environment setting method preferably includes a step of receiving data of the building information model before the step of displaying the target space on the screen of the monitor device 22.

  According to this technique, it is possible to perform the work of creating the building information model data (BIM data) and the work of setting the light environment separately. Therefore, an expert who designs the structure of the building and an expert who sets the light environment can demonstrate their specialized knowledge.

  The above-described embodiment is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiment, and various modifications can be made according to design and the like as long as the technical idea according to the present invention is not deviated from this embodiment. Of course, it can be changed.
