Description

TECHNICAL FIELD This disclosure relates to environmental control systems.

ABW (Activity Based Working) offices are emerging as a result of work style reform. ABW offices are designed to handle the ever-changing types and amounts of work, as well as the workers' own emotions and feelings, such as when a worker wants to do concentrated work alone, when they want to work in a group, or when they want to take a break and relax. This is a type of office that improves the efficiency of worker and organizational performance by allowing workers to select spaces with different design objectives in response to their motivations and intentions. As an example of how to create spaces with different design purposes, there is known a method of creating spaces with the purpose of increasing the efficiency of concentrated work using fixtures and furniture and zoning them, as described in Patent Document 1, for example.

Japanese Patent Application Publication No. 2017-131572

Ideally, the zoning of an ABW office would be continuously changed according to the fluid work performance of workers and organizations and the needs of each space. For example, even after the aforementioned booth-type fixtures and furniture have been installed, the zoning can be changed by changing the arrangement and number of the booth-type fixtures and furniture in response to excess or deficiency in usage. However, the work performance of workers and organizations and their needs for each space can occur in cycles such as hourly, daily, and monthly, so tasks such as transporting and reinstalling fixtures and furniture, and storing them in warehouses are It is difficult to continuously implement the ABW office in terms of the time and labor involved, and there are issues with the flexibility of design changes as a means of realizing an ABW office.

Therefore, the purpose of this disclosure is to provide environmental control that enables active zoning that easily responds to the fluid work performance of workers and organizations and the needs of each space that occur in cycles such as hourly, daily, and monthly. The goal is to provide a system.

In order to solve the above problems, an environmental control system according to the present disclosure includes one or more task lights for illuminating a visual target area indoors, and a plurality of task lights for illuminating a wider area than the visual target area indoors. a base light and a control device, the control device includes a dimming/coloring signal transmitting unit that transmits a signal to control dimming/toning to the task light and the base light, and a control device that transmits a signal for controlling dimming and color toning to the task light and the base light, and a storage unit that stores position information of the light and base light, and device identification information; It is possible to perform one or more group controls in which dimming/toning control of at least one task light and a plurality of base lights are performed in conjunction with each other, and the one or more group controls include at least one task light. Control for controlling at least one task light and a plurality of base lights so that when the task lights are turned on, the light intensity of the base lights installed in the vicinity thereof is equal to or less than the light intensity of the base lights in the area where the task lights are not lit. is included.

Note that the amount of light from the base light installed in the vicinity area may be zero. Furthermore, the base light installed in the above-mentioned nearby area refers to one or more base lights that can dominantly illuminate the viewing target area illuminated by the task light, including the base light closest to the lit task light. shall be taken as a thing. Furthermore, the base light in the area where the task light is not lit refers to one or more base lights that cannot dominantly illuminate the viewing target area illuminated by the lit task light.

Here, the requirement of "dominantly illuminating" means that the illuminated task light achieves the largest amount of luminous flux among all installed base lights for the viewing target area illuminated. The origin luminous flux ratio is defined as the ratio of the luminous flux that reaches the viewing target area to the total luminous flux emitted from the base light at the position of the base light (hereinafter referred to as the origin), and the ratio of half of the origin luminous flux ratio When the value is defined as the effective luminous flux ratio, it is satisfied in the case of a base light where the ratio of the luminous flux that reaches the viewing target area to the total luminous flux that is emitted is greater than or equal to the effective luminous flux ratio and less than or equal to the origin luminous flux ratio. .

Next, to make it easier to understand, a specific example will be used to explain whether or not the requirement of "dominantly illuminating" is satisfied. FIG. 13 is a perspective view illustrating an XYZ three-dimensional simulation model defined by the ray tracing simulation software LightTools. As shown in FIG. 13, the bottom surface of a 1218 mm x 78 mm plate-shaped object was defined as a light source section, and the top surface of a 700 mm x 1200 mm plate-shaped object was defined as a light receiving section. Further, the distance between the light source section and the light receiving section was 1800 mm. Note that these approximately reflect the size and light distribution of the light source and work desk used in the examples described in this specification, and the distance between the top surface of the desk and the light source section.

Figure 14 shows the state in which the center coordinates of the light source and light receiving part are aligned as shown in Figure 13, and the energy reaching the light receiving part when the positional coordinates of the light source are offset in the X-axis direction from that state. It is a graph showing the ratio of amounts. Note that the rate of energy reaching the desk surface on the vertical axis indicates a luminous flux ratio that indicates the percentage of the amount of luminous flux that has reached the desk surface, which is the viewing target area, when the total amount of luminous flux emitted from the light source is 100%. . In this specific example, as shown in FIG. 14, the origin luminous flux ratio, which represents the luminous flux ratio when the base light exists at the position coordinates of x=0 mm and y=0 mm, is 7.1%. As a result, the effective luminous flux ratio is found to be 7.1×0.5=3.55%. From this, it can be determined that a base light that satisfies the requirement of "dominantly illuminating" has a ratio of 3.55% to 7.1% of the amount of luminous flux that reaches the desk surface out of the total amount of luminous flux emitted. From this simulation result, for example, the following can be mentioned.

In this specific example, in a 1218 mm x 78 mm base light installed at a height of 1800 mm from a 700 mm x 1200 mm visual target area, the amount of luminous flux that reaches a certain visual target area out of the total luminous flux emitted from the base light. A base light whose ratio is in the range of 3.55% to 7.1% is a base light that predominantly illuminates a certain viewing target area. In other words, if the ratio of the amount of luminous flux that reaches a certain viewing target area out of the total amount of luminous flux emitted from the base light is less than 3.55%, it is a base light that cannot dominantly illuminate a certain viewing target area. be. The total luminous flux of the base light can be measured using a known measurement/analysis method such as an integrating sphere and a spectrophotometer, and the luminous flux reaching the viewing target area can be measured using a known measurement/analysis method such as a luminometer. measurable using means. Furthermore, it is obvious that the above derivation method can be universally applied to changes in the size and light distribution of the light source, the size of the viewing target area, the height distance from the light source, etc., and under any conditions. It is also applicable to In addition, as in this specific example, by reflecting the actual light source size and light distribution in the simulation setting conditions and running the simulation, it is possible to create a base light that dominantly illuminates a certain viewing target area. It is possible to determine whether or not a certain base light is dominantly illuminating a certain viewing target area by understanding the actual size and illuminance using a well-known illumination meter etc. It is possible to judge.

According to the environmental control system according to the present disclosure, active zoning that easily responds to the fluid work performance of workers and organizations and the needs for each space that occur in cycles such as hourly, daily, and monthly is possible. Become.

[Example 1]
FIG. 1 is a drawing showing an example of a possible layout of a plurality of work desks D01 to D14 in an ABW office 20 as an example of a room in which an environmental control system 10 according to a first embodiment of the present disclosure is installed. Yes, the layout when looking at multiple work desks D01 to D14 from above and the layout of the base light 3, duct rail 4 for electricity supply, and spotlight 5 installed on the ceiling of the ABW office 20 are shown in the work desks D01 to D14. It is a layout arrangement diagram written in a form superimposed on the arrangement of D14.

In one form of the ABW office 20 shown in FIG. 1, a total of 14 work desks D01 to D14, which are general office desks, are classified into desk group 1 and desk group 2, and the ABW office 20 is placed above them. Twenty-eight LED dimming and color control type base lights (for example, NNLK41515+NNL4600EXDK9: Panasonic) were installed at equal intervals as ambient lighting for illumination, and three rows of duct rails 4 for power supply were installed in the vicinity. Specifically, a total of 14 work desks D01 to D14 are arranged in four cases, and three duct rails 4 for power supply are placed near three rows of work desks D01 to D14 among the four work desks D01 to D14. They were arranged so as to extend in a direction substantially parallel to the extending direction of the rows.

Furthermore, a total of 14 LED dimming type spotlights (for example, NTS05121W: Panasonic) 5 as an example of task lights were installed on each duct rail 4. In addition, a wavelength conversion filter was attached to the opening of each spotlight 5, and the color temperature of the output light from the spotlight 5 was adjusted to 6000K. Then, a total of 14 work desks D01 to D14 and a total of 14 spotlights 5 are made to correspond one-to-one, and each spotlight 5 illuminates the center of the corresponding work desk D01 to D14. Adjusted the installation position and installation direction of spotlight 5.

In addition, the 28 base lights 3 and the 14 spotlights 5 are controlled by a multi-manager (for example, NQ51101: Panasonic), an LS/PD signal conversion interface (for example, NK51111: Panasonic), and a PD/control device as an example of a control device. It was sequentially connected to an optical signal conversion interface (for example, NK51012: Panasonic) and a PiPit+separate cell controller A type (for example, NQ23171Z: Panasonic) via a dimming signal line. Note that seven spotlights 5 were paired with two PiPit+separate cell controllers A type.

Next, using the multi-manager operation application, the position information of each base light 3 is memorized by mapping the 28 base lights 3, and as shown in Fig. 1, the position information of each base light 3 is stored. Spotlights 5 are set as lighting devices belonging to lighting group 1, four base lights 3 are set as lighting devices belonging to lighting group 2, and 12 base lights 3 and six spotlights 5 are set as lighting devices. It was set as a lighting device belonging to Group 3. Furthermore, as shown in FIG. 2, four scenes were set for each of the lighting groups 1 to 3, and in each scene, the color temperature and dimming rate values were set for each group.

Here, setting of each scene can be easily performed using an information terminal in which an existing scene setting application is installed, such as a smartphone, a tablet, or a remote control. Then, each scene was actually recreated. Specifically, when scene 1 was played back using the operation unit 64 (see Figure 3) after the blind curtains on the windows of ABW office 20 were completely closed, desk group 1 and desk group 2 were visually divided. . Subsequently, when other scenes such as scene 3 and scene 4 were sequentially reproduced using the operation unit 64 (see FIG. 3), each scene was switched in about a few seconds.

Desk group 1 in scene 1 had an uneven illuminance distribution in which the illuminance was high only in the center of the work desks D07 to D014, and the illuminance decreased as the distance from the center increased. In addition, the illuminance of the floor and walls around the work desk was low, giving the space a low sense of brightness. On the other hand, in desk group 2 of scene 1, the illuminance of work desks D01 to D06 has a more uniform illuminance distribution compared to desk group 1, and the illuminance of the floors and walls around the work desk is also high, giving a high sense of brightness. It was space.

At this time, when a worker is seated in desk group 1, the illuminance is high only in the center of work desks D07 to D014, which the worker should pay more attention to, reducing cognitive noise factors in peripheral vision. It is easier to immerse yourself in work and improve the efficiency of concentrated work. Furthermore, in this method, by setting the dimming rate of the base light 3 low, the visibility of peripheral vision such as walls and floors is reduced, so it is easier to concentrate on the work desks D07 to D014 and the work. Easy to increase effectiveness. Additionally, because the dimming rate of base light 3 is set low, workers working in desk group 1 may not be able to clearly see their facial expressions when other workers see them from the outside, or It is difficult to talk to him because his shadow makes him look moody. In other words, the worker working in this desk group 1 is likely to be talked to by other workers and the probability of work being interrupted is likely to decrease, and as a result, the efficiency of concentrated work is likely to be improved. From the above, when scene 1 is reproduced, desk group 1 is a space that easily functions as a concentration space. On the other hand, in scene 1, desk group 2 has a low color temperature and is a space that easily functions as a co-creation space because it facilitates relaxation and communication among multiple people.

Desk group 1 and desk group 2 have significantly different spatial illuminance distributions. In particular, desk group 1 is characterized by lower illuminance around the work desk, such as the floor and walls, and this is a factor, giving a strong sense of spatial division between the two desk groups. Furthermore, since the color temperature of the lighting between desk group 1 and desk group 2 is significantly different, there is a strong sense of space division in appearance. From the above, it has a zoning effect that visually separates spaces without using fixtures or furniture. The greater the difference in illuminance distribution and color temperature between groups, the easier it is to enhance the zoning effect.

In addition, desk group 1 and desk group 2 differ in the work content they encourage workers to perform.For example, in this embodiment, desk group 1 encourages concentrated work, while desk group 2 encourages relaxation and communication, so it is only visually appealing. This effect also contributes to the zoning effect, as it also creates differences in how each space is used functionally.

When zoning is performed using this method, switching between each scene can be completed in a few seconds, and as a result, it is possible to change the layout of an office in a few seconds. For example, on days when the need for concentration space is high, such as on a busy day in the office, switching from scene 1 to scene 3 will increase the number of seats in the office concentration space from 8 to 14, meeting the concentration space needs of workers. By fulfilling these requirements, it becomes easier to improve the work performance of workers and organizations. Alternatively, in the case of a fallow day, by switching to scene 4, the number of seats in the concentration space becomes 0 and the number of seats in the co-creation space becomes 14, which has the effect of reducing stress in the organization and increasing the amount of communication. Furthermore, it is also possible to adjust the number of seats in the afternoon concentration space during the lunch break by referring to the utilization rate of the concentration space in the morning of a given day. According to this method, active zoning that changes the layout on an hourly, daily, monthly, or other cycle is possible, which is difficult with the method using fixtures and furniture as described above. In conventional office scenes, areas such as work desks and hallways are generally illuminated with highly uniform color temperature and illuminance distribution. On the other hand, since the present invention uses such a lighting method and control method, it is possible to achieve remarkable effects that could not be foreseen with conventional lighting knowledge, especially in ABW office scenes.

FIG. 3 is a block diagram showing the main configuration of the environmental control system 10. As shown in FIG. 3, the environmental control system 10 includes a control device 61 including a base light 3, a spotlight 5, and a multi-manager, as well as an operation section 64. , a dimming/toning signal transmitting section 61b, and a storage section 61c. The control device 61 is preferably configured by a computer, for example, a microcomputer, and the control unit 61a, that is, the processor, includes, for example, a CPU (Central Processing Unit). Furthermore, the storage unit 61c is composed of a non-volatile memory such as a ROM (Read Only Memory) and a volatile memory such as a RAM (Random Access Memory). The CPU reads and executes programs etc. stored in advance in the storage unit 61c. Furthermore, the nonvolatile memory stores in advance a control program, predetermined threshold values, and the like. Further, the volatile memory temporarily stores read programs and processing data. The storage unit 61c stores position information and device identification information regarding each of one or more spotlights 5 and a plurality of base lights 3 that are set in advance. Further, the storage unit 61c stores data on light adjustment and color adjustment for reproducing the above-described scenes 1 to 4. In the first embodiment, eight work desks D07 to D014 belong to desk group 1, and six work desks D01 to D06 belong to desk group 2, but the work desks belonging to desk group 1 and desk group 2 The number of is not limited to the case of the first embodiment. Further, the number of lighting groups is not limited to three as in the first embodiment, and any number of lighting groups greater than or equal to two may exist. Next, position information, device identification information, and each configuration of the environmental control system 10 will be described in detail.

(About information)
<Location information>
Position information can be information similar to the absolute value of coordinates, such as the actual position in space, or relative positional relationship based on a certain spotlight, base light, or existing pillar in the space. information is also acceptable. Further, the position information stored in the storage unit 61c does not need to be able to completely reproduce the positions and positional relationships of the actually installed spotlights and base lights, and may be information that can only partially reproduce (define) them. Furthermore, the position information may be recorded in the storage unit based on user input, or may be recorded using AI or computer algorithms. Further, the position information may be set and recorded by referring to drawing data stored in a separate storage unit or by being associated with the drawing data. Further, the position information does not need to be assigned to or associated with all devices included in the environmental control system, and may be selectable as appropriate depending on the user's circumstances.

<Device identification information>
The device identification information is information by which a device such as a spotlight or a base light can be identified, and includes, for example, a manufacturing number, a MAC address, an IP address, a product number, and the like. Device identification information is used when setting and recording the aforementioned location information, groups, and scenes, or when individually setting and recording output parameters (color toning rate, dimming rate, etc.) of each device. Used in a control system to prevent different devices from being unintentionally identified as the same. The device identification information does not need to be assigned or associated with all devices included in the environmental control system, and the devices to be assigned or associated can be selected as appropriate depending on the user's circumstances.

(Specific aspects of each configuration)
<Task light>
The device form of the task light is not particularly limited, and in addition to the spotlight 5 mentioned above, desk lights, downlights, etc. can be adopted as the task light. It is preferable that the light distribution be controlled such that light is concentrated in a certain area, since it is easy to control the illumination range of the work desk. More specifically, the spotlight 5 may have a structure shown in a perspective view in FIG. 4, that is, a structure in which the irradiation direction of the spotlight 5 is adjusted by applying an external force, as shown in FIG. 5(a). , (b) shows a perspective view, that is, it has a structure in which the irradiation direction of the spotlight 5 can be automatically adjusted in any downward direction by freely rotating the two rotating shafts with a motor or the like using a remote control. It can be anything. If at least one spotlight 5 is as shown in FIGS. 5(a) and 5(b) and the direction of emission of illumination light can be changed in any direction at the installation position, it is possible to install the spotlight 5 on a work desk in the longitudinal direction in a concentrated space. Not only can the degree of freedom of the gaps between the work desks be increased, but also the degree of freedom of the gaps between the work desks in the width direction in the concentration space can be increased, and the degree of freedom of the layout of the concentration space can be increased. Furthermore, if at least one spotlight 5 is of the type shown in FIGS. 5(a) and 5(b), in which the irradiation direction of the spotlight 5 can be freely adjusted with a remote control, it is possible to safely spot the spotlight from the ground without using a stepladder or the like. The irradiation direction of the light 5 can be adjusted. More specifically, as described above, it is preferable to use a dimming and color control type spotlight as the task light.

The task light is lighting for increasing the efficiency of a worker's work, such as computer operation work, writing work, reading work, etc., and is lighting that selectively irradiates a viewing target area of a work desk. The visual target area is the area that can generally be seen when working at a work desk.For example, when operating a personal computer (hereinafter simply referred to as a computer) placed at the back of the center of the work desk. In this case, the center of the work desk is the center of the visual target area. At this time, we do not take into account changes in the visual object due to physiological factors or accidental changes in posture or line of sight.In other words, we do not take into account changes in the visual object due to physiological factors or accidental changes in posture or line of sight.In other words, we do not take into account changes in the visual object due to physiological factors or accidental changes in posture or line of sight. Events such as shifting one's gaze to the floor due to a cough or shifting one's gaze because someone is speaking to the user are not considered as significant changes in the visual target area at the work desks D01 to D14.

The illumination range of the task light is preferably limited to a part of the viewing target area, and for example, it is preferable that the illumination range covers 30% to 90% of the area of the work desk. Although the illumination range of the task light is not particularly limited, it is preferably approximately circular or polygonal. By doing this, the brightness of the viewing target area becomes brighter than the brightness of the area that is not the viewing target area, and cognitive noise in the peripheral visual field is reduced. Therefore, the worker's consciousness is directed toward the work desk, making it easier to improve work efficiency.

Here, the illumination range can be calculated as the position where the maximum amount of light per unit area reaching the work desk is halved, and is generally a range called half width. The illumination range can be measured and calculated using a known illumination meter. The color temperature of the task light is not particularly limited, but a color temperature of 4000K to 6500K is preferable because it facilitates cognitive improvement in concentration.

<Base light>
The base light is lighting to increase the brightness of the room, and is lighting that evenly illuminates the room. The light distribution of the base light is preferably wider than that of the spotlight in order to uniformly illuminate the room. The color temperature of the base light is not particularly limited. It is preferable that the base light is of a light control type. The device form of the base light is not particularly limited, and any device such as a ceiling light, line light, pendant light, spotlight, light bar, etc. can be used.

<Control device>
The control device 61 is a device for controlling the task light and the base light. Here, the control includes ON/OFF control and dimming/color adjustment control. Although the device form of the control device 61 is not particularly limited, for example, the lighting control device and the control application for the lighting control device described in Example 1 can be suitably adopted as the device form of the control device 61. In addition to the tablet shown in FIG. 3, the device control application may be installed on another terminal such as a personal computer or a smartphone. In this case, it is preferable because the user can easily set, manage, and operate the lighting control device.

In the example shown in FIG. 3, the control device 61 is included in the tablet 60, but the control device does not necessarily have to be included in an operation terminal such as a tablet, and as shown in FIG. The control device 71 of 70 may be a terminal or device other than the operating terminal such as the tablet 72. Here, the control device 71 may have a casing embedded in a ceiling or wall surface, or may be placed on the ground, a storage shelf, or the like. Further, the control device 71 may be controlled by wired signal communication with an information terminal such as the tablet 72, or may be controlled by wireless signal communication such as Wi-Fi or Bluetooth (registered trademark). . In this case, although not particularly shown in FIG. 6, the control device 71 may include a communication device having a port for connecting a communication signal line and a wireless LAN access point. Furthermore, at this time, the tablet 72 and the like do not need to directly communicate with the spotlight 5 and the base light 3. At this time, information on the positions and control conditions of the appliances that make up the environmental control system 70, such as mapping, scenes, groups, control schedules, etc., set using the operation unit 75 of the tablet 72 is transmitted to the control device 71. The data may be recorded in the storage unit 76 of 71. In this case, even if the power of the tablet 72 is turned off or the tablet 72 is stored outside the communication range of the spotlight 5 or the base light 3, the intended environment control can be performed. Further, the control device 71 does not need to have a user interface for operation such as a liquid crystal display. In this case, the control device 71 is preferable because it can be easily miniaturized, and the ease of installation and design are improved. Although not particularly shown in FIG. 6, the operating terminal such as the tablet 72 may have a storage unit. The environmental control system 70 shown in FIG. 6 is a modification of the environmental control system 10, 110 shown in FIG. 3 or FIG. 8, which will be described later. It is clear that there are many embodiments of environmental control systems.

<Dimmer color adjustment signal transmitter>
The light adjustment color signal transmitting unit 61b is a part that transmits a light adjustment color signal to the task light and the base light to execute at least one of light adjustment and color adjustment, and is included in the control device 61. be. The signal format is not particularly limited, and any format such as a known dimming signal, Wi-Fi, or BlueTooth (registered trademark) can be used. In addition, in the above-mentioned light adjustment color control, the light adjustment color adjustment control using the digital control method was explained, and the control method in which the digital signal (PDCL) was transmitted from the light control was explained. Here, in this control method, wiring of a signal line for digital control is required in addition to a power supply line. With this digital control, since detailed information can be communicated, control using a large amount of information can be performed, and control using wireless signals is also included in this method.

However, when performing the dimming color control, a phase control method may be adopted, or the dimming control may be executed by directly adjusting the power to the lighting equipment. This method directly controls the power supply current to the lighting equipment, so it is susceptible to voltage fluctuations, but it is easy to install because there is no need to run separate dedicated signal lines. Alternatively, when performing dimming and color control, a signal line method may be adopted, in which a dimming signal (duty signal) is sent from the light control, and the brightness of the light emitting part such as an LED is controlled by the power supply unit on the equipment side. May be controlled. This method requires wiring for a dimming signal line in addition to the power supply line, but it is less susceptible to the effects of wire voltage, allowing smooth dimming control without flickering. Note that control of only ON/OFF of the task light and base light is also included in dimming control.

<Storage section>
Any known device may be employed as the device constituting the storage section. Further, unlike the configuration shown in FIG. 3, the storage unit does not need to be built into the control device, and may be installed in an information terminal other than the control device including the control device, such as a smartphone, a tablet, or a personal computer. Alternatively, it may be configured with a server or workstation on the cloud, an external storage medium, or the like. The storage unit is basically set by the user, but it can also be rewritten and set by a machine using the cloud or AI.

<Group information for multiple devices>
Group information for multiple lighting devices is managed, for example, by an app. Grouping may be set and saved by operating a tablet terminal, for example. The same command is sent to a plurality of grouped devices all at once, and, for example, similar dimming and color control is performed. Note that with regard to dimming and color adjustment control of a plurality of grouped devices, that is, group control, signal delays are allowed, and variations in the operation of the devices are also allowed. For example, an acceptable variation in equipment operation is within 30 minutes, more preferably within 10 minutes, even more preferably within 1 minute, and most preferably within 10 seconds, and signals falling within this range or Instruction delay is included in the behavior of multiple devices that are grouped together. It is preferable if the variation in the operation of the equipment is within the above-mentioned time period, because the layout change can be easily accomplished quickly and with less labor than a layout change that typically involves transporting and reinstalling fixtures and furniture. Group settings may be included as a function of an application that operates a control device, but are not necessarily defined under the name "group." It is preferable to set groups in an application that operates the control device or in a storage unit included in the control device because this makes it easier for the user to manage and change the lighting and its control parameters.

<Control scene information>
Setting and reproducing control parameters such as dimming rate and color toning rate for each of a plurality of lighting devices is a very complicated task for the user. This is because a typical ABW office uses 10 or more lighting devices, or 30 or more, and in many cases, 100 or more lighting devices. Therefore, a method is known in which control parameters for a plurality of lighting devices are collectively stored in a storage unit and managed, and this method is referred to as a scene in this application. By doing this, it is not only easier for the user to manage control parameter conditions for multiple lighting devices, but also it is possible to instantly reflect those conditions to multiple lighting devices at a desired timing (hereinafter referred to as This is preferable because it also facilitates regeneration (referred to as regeneration). Furthermore, by storing a plurality of types of scenes in the storage unit in advance, the user can instantly switch between two or more intended setting conditions. The settings for each scene may be set in any way depending on the specification needs. For example, unlike the example shown in FIG. The data may be stored in the storage unit, and the dimming rate of the ten base lights described above may be set to 30% in scene 2 and stored in the storage unit. Then, if you play scene 1, the dimming rate of the 10 base lights will instantly change to 100%, and if you play scene 2 from this state, the 10 base lights will instantly change to a state where the dimming rate is set to 100%. The light control rate may be set to 30%. This is preferable because it is possible to realize dimming control of a large number of lighting devices in a much shorter time and with less labor than resetting the dimming rate of 10 lighting devices every time. Note that scene settings may be included as a function of an application that operates the control device, but are not necessarily defined under the name "scene." Furthermore, each scene may be set for groups 1 and 2 as follows. For example, in scene 1, group 1: dimming rate may be set to 0%, group 2: dimming rate may be set to 50%, and in scene 2, group 1: dimming rate is 50%, group 2: dimming rate is 0. It may be set to %. By setting up the scene in this way, you can instantly switch between a zone where workers can easily concentrate and a zone where workers can relax and communicate with other workers, even if the two zones are of different sizes. In addition, the size of each zone can be changed instantaneously depending on needs. Note that with respect to lighting and color adjustment control of a plurality of scene-based devices, that is, group control, signal delay is allowed, and variations in the operation of the devices are also allowed. For example, an acceptable variation in equipment operation is within 30 minutes, more preferably within 10 minutes, even more preferably within 1 minute, and most preferably within 10 seconds, and signals falling within this range or Instruction delays are included in the behavior of multiple devices that are scened.

(Example 1 configuration and effects)
The control in the environmental control system 10 of the first embodiment and specific aspects of each configuration have been described above. In this section, the essential configuration of the environmental control system 10 and its effects, as well as the preferable configuration and its effects when adopted, which have become clear from the above description, will be explained.

<Essential configuration and effects derived from the configuration>
The environmental control system 10 includes one or more spotlights (task lights) 5 for illuminating a viewing target area (near the center of the upper surface of the work desks D01 to D14) in the ABW office (room) 20, and It includes a plurality of base lights 3 for illuminating a wider area than the viewing target area in 20, and a control device 61. The control device 61 also includes a dimming/toning signal transmitter 61b that transmits a signal for controlling dimming/toning to the spotlight 5 and the base light 3, and a dimming/toning signal transmitter 61b that transmits signals for controlling dimming/toning to the spotlight 5 and the base light 3, and and a storage section 61c that stores location information and device identification information. In addition, the control device 61 uses the information stored in the storage section 61c to control the dimming/adjustment of at least one spotlight 5 and the plurality of base lights 3 according to the signal transmitted from the dimming/coloring signal transmitting section 61b. It is possible to perform one or more group controls that perform color control in conjunction. For one or more group control, when eight spotlights 5 belonging to group 1 as an example of at least one spotlight 5 are turned on, a base light 3 as an example of the base light 3 installed in the vicinity thereof is turned on. The light intensity of the eight base lights 3 closest to each of the eight spotlights 5 is the same as that of the 20 base lights other than the eight base lights 3, which is an example of a base light in an area where no task light is lit. This includes control for controlling 8 spotlights 5 and 28 base lights 3 so that the light intensity is equal to or less than 3.

Therefore, as explained in detail above, the area near the spotlight 5 that is lit can be separated from the area where the task light is not lit, and the area near the spotlight 5 that is lit can be divided into areas where people are concentrated. It can be made into an easy area.

<Multiple configurations that are preferable to select and the effects derived from each configuration>
Further, information on lighting groups 1 to 3 of the plurality of devices 3 and 5 (group information) may be stored in the storage unit 61c. Information on lighting groups 1 to 3 of multiple devices 3 and 5 may include information on multiple groups (lighting groups 1 and 3) in which one or more spotlights 5 and one or more base lights 3 are mixed. good. Furthermore, as in the control of scene 1 in FIG. Base lights 3 included in lighting group 2 that are not included, or some or all of the base lights included in lighting group 3 that has one or more spotlights 5 but does not have a lit spotlight 5. The amount of light may be controlled to be less than or equal to the amount of light.

According to this configuration, when the spotlight 5 is turned on, the area illuminated by the plurality of lighting devices included in the same lighting group 1 is placed in perspective with respect to the area illuminated by the lighting devices belonging to other groups. You can make it darker. Therefore, it is possible to emphasize the sense of division of the space in appearance, and it is possible to make the area illuminated by the plurality of lighting devices included in the lighting group 1 lit by the spotlight 5 into a space where people can more easily concentrate. .

Further, control scene information may be stored in the storage unit 61c. In addition, the control scene information includes information on one or more first scenes (first to third scenes in FIG. 2) in which the spotlight 5 is lit, and information on one or more second scenes (in the figure) in which the spotlight 5 is not lit. (4th scene of 2) may be included. In addition, in a plurality of scenes where one or more spotlights 5 and a plurality of base lights 3 can be realized, one or more spotlights 5 and a plurality of base lights 3 are installed in the vicinity of the spotlight 5 in the first scene (the first to third scenes in FIG. 2). In the first scene (see FIG. 2), the light amount of the base light 3 is controlled to be equal to or less than the light amount of the base light 3 installed in the vicinity of the spotlight 5 in the second scene (the fourth scene in FIG. 2). (first to third scenes) and a second scene (fourth scene in FIG. 2).

According to this configuration, other group controls can be executed instantly in order to reproduce other scenes, so switching between each scene can be executed instantly, and the office layout can be changed in a few seconds according to needs. . Therefore, it is possible to realize active zoning that easily responds to the fluid work performance of workers and organizations and the needs for each space that occur in cycles such as hourly, daily, and monthly. Furthermore, when it is easier to reduce organizational stress and increase the amount of communication by reducing the area of concentration space, such as on a fallow day, the scene can be instantly switched to the second scene (fourth scene in Figure 2). can. Therefore, it is possible to realize an ABW office 20 with a high degree of freedom in meeting needs.

Further, group information and control scene information of the plurality of devices 3 and 5 may be stored in the storage unit 61c. In addition, the control scene information is associated with group information, as shown in the first scene of FIG. Information about a scene that occurs when two lighting groups 2) are adjacent to each other may also be included.

According to this configuration, the area surrounding the area where the spotlight 5 is lit can be made darker. Therefore, the degree of division of the region where the spotlight 5 is lit with respect to the surrounding region can be increased.

Further, group information and control scene information of the plurality of devices 3 and 5 may be stored in the storage unit 61c. In addition, as shown in the first scene of FIG. 2, the control scene information is associated with group information, and the illumination light of the group in which the spotlight 5 is lit (lighting group 1 in FIG. 2) and the spotlight 5 is not lit. Information on a scene including the illumination light of the group (lighting group 3 in FIG. 2) may also be included. In addition, the amount of light per unit area reaching the viewing target area of the spotlight 5 from the base light 3 included in the group where the spotlight 5 is lit (illumination group 1 in FIG. 2) is different from the group where the spotlight 5 is not lit (illumination group 1 in FIG. The amount of light reaching the viewing target area of the spotlight 5 from the base light 3 included in the lighting group 3) in FIG. 2 may be controlled to be less than or equal to the amount of light per unit area.

According to this configuration, the viewing target area can be intensively illuminated with light from the spotlight 5 in the concentrated space. Therefore, it is possible to more effectively arouse people's concentration.

Further, group information and control scene information of the plurality of devices 3 and 5 may be stored in the storage unit 61c. In addition, as shown in the first scene of FIG. 2, the control scene information is associated with group information, and the illumination light of the group in which the spotlight 5 is lit (lighting group 1 in FIG. 2) and the spotlight 5 is not lit. Information on a scene including the illumination light of the group (lighting group 3 in FIG. 2) may also be included.

Further, group information and control scene information of a plurality of devices may be stored in the storage unit. Further, the control scene information may include a scene that is associated with the group information and includes illumination light of a group where the task light is turned on and illumination light of a group where the task light is not turned on. In addition, the amount of light per unit area reaching the visual target area of the task light from the task light and base light included in the group where the task light is lit is The amount of light reaching the viewing target area may be controlled to be less than or equal to the amount of light per unit area.

According to this configuration, the area where the task light is lit can be made darker than the surrounding areas. Therefore, the degree of division of the area where the task light is lit from the surrounding area can be increased.

Further, group information and control scene information of a plurality of devices may be stored in the storage unit. Further, the control scene information may include information about a scene that is associated with the group information and includes illumination light of a group where the task light is turned on and illumination light of a group where the task light is not turned on. Also, the amount of light per unit area reaching the visual target area of the task light from the base light included in the group where the task light is lit, and the visual target area of the task light from the base light included in the group where the task light is not lit. The amount of light per unit area that reaches each area may be controlled to be larger than the amount of light per unit area that reaches a region that is not the viewing target area.

According to this configuration, the work area in the concentration space and the co-creation space can be made brighter than the area that is not the viewing target area, and efficient work can be promoted in both the concentration space and the co-creation space.

Furthermore, as described above, even if the scenes are not intentionally switched instantaneously, significant effects may be obtained. Specifically, the scenes may be changed gradually over a predetermined period of time or more, for example, over 30 minutes.

According to this configuration, since the scene is gradually changed over a predetermined period of time or more, it is possible to shift to a concentration zone, for example, without making the worker aware of the change. Therefore, it is easier for workers to naturally shift to concentrated work. For example, by performing this control about two hours before the scheduled end time of work, it is easier to reduce overtime hours for workers, and as a result, it is less likely to accumulate mental and physical stress. ABW offices will become easier to realize. Or, because your peripheral vision darkens without you noticing, you may be psychologically reluctant to go home, just as farmers before the invention of clocks would finish their work and instinctively go home at sunset. It can also be expected to have the effect of making it easier to focus on employees, and as a result, reduce overtime hours for workers, making it easier to create an ABW office where physical and mental stress is less likely to accumulate.

In the case of this modification, the time for switching each scene is not particularly limited as long as the effect can be achieved. For example, the time for switching each scene may be any time between 10 minutes and 70 minutes, and for example, the above-mentioned 30 minutes or 60 minutes can be suitably adopted. In addition, the scene transition during scene switching is based on a mixing condition of the lighting and color adjustment conditions of the scene before the change and the lighting and color adjustment conditions of the scene after the change, in a ratio that corresponds to the elapsed time, that is, a so-called cross-fade-like scene. It may be a transition. Alternatively, one or more other scenes may be played while the scene is being switched, or the scenes may be gradually switched using an animation method. In this way, it is impossible to change the layout gradually so as not to be noticed by the workers, which is impossible by changing the layout using conventional fixtures and furniture, and is a remarkable effect of the present invention.

In the first embodiment, a case has been described in which the storage unit 61c stores group information of the plurality of devices 3 and 5 set in advance and control scene information. However, the storage unit only needs to store position information and device identification information of one or more task lights and a plurality of base lights set in advance, and group information of one or more task lights and a plurality of base lights. , and control scene information, or both may not be stored. The control device of the environmental control system of the present disclosure includes position information and device identification information of one or more task lights and a plurality of base lights, and at least one of the position information and device identification information of a lit task light. When at least one task light is turned on, based on the information of It is sufficient to be able to control one task light and multiple base lights.

[Example 2]
In the first embodiment, a case has been described in which zoning is performed using illumination light, but zoning may be performed using not only illumination light but also sound output. In Example 2, zoning using not only illumination light but also acoustic effects will be described.

FIG. 7 is a layout diagram corresponding to FIG. 1 in the environmental control system 110 of the second embodiment. Further, FIG. 8 is a block diagram corresponding to FIG. 3 in the environmental control system 110 of the second embodiment. As shown in FIG. 7, the environmental control system 110 differs from the environmental control system 10 of the first embodiment in that a plurality of speakers 109 (for example, LSPX-103E26: Sony) are attached to the duct rail 104. Further, as shown in FIG. 8, in the second embodiment, the control device 161 of the environmental control system 110 includes a sound signal transmitter 161c in addition to the dimming/color adjustment signal transmitter 161b, and outputs signals to the plurality of speakers 109. Outputs a signal containing sound information. The sound control unit of the environmental control system 110 may be built into any information device, for example, a personal computer, a tablet, a smartphone, a single board computer, or the like.

To explain in more detail the acoustic effects of the plurality of speakers 109, in the environmental control system 110, four first to fourth speakers 109a to 109d are attached to the duct rail 104, and each speaker 109a to I connected the 109d wirelessly in stereo. Further, the first speaker 109a and the second speaker 109b constitute the speaker group 1, and the third speaker 109c and the fourth speaker 109d constitute the speaker group 2. The first and second speakers 109a and 109b belonging to speaker group 1 output the same first audio content, and the third and fourth speakers 109c and 109d belonging to speaker group 2 output the same second audio content. is now output. The first and second speakers 109a and 109b belonging to speaker group 1 output sound to people present in the area of desk group 1, and the third and fourth speakers 109c and 109d belonging to speaker group 2 output sound to people who are present in the area of desk group 1. A sound is output to people existing in the area of group 2. Note that the number of speakers belonging to speaker group 1 may be any number, and the number of speakers belonging to speaker group 2 may also be any number. Further, as the speaker 109, a directional speaker, for example, a parametric speaker, etc. may be employed. Because parametric speakers use ultrasonic waves, they can produce a sound that is highly directional.

With this configuration, for example, sound content in which the sound of a babbling stream was recorded was played back from the speaker group 1 located at the top of the desk group 1 via a smartphone. At the same time, sound content recorded with jazz and bossa nova music was played from speaker group 2 located at the top of desk group 2 via a different smartphone than the one mentioned above. Here, when I was seated at a desk belonging to desk group 1, I could hear the sound of a babbling stream, and I could only faintly hear jazz and bossa nova music. On the other hand, when I was seated at a desk belonging to desk group 2, I could hear jazz/bossa nova music and only the faint sound of a babbling stream. From the above, it has been confirmed that, for example, with such a configuration, it is possible to selectively provide different contents to different desk groups.

Furthermore, in the second embodiment, in addition to outputting sound from the speaker groups 1 and 2, the scene described in the first embodiment was also reproduced. Information on the sound output by each lighting device in each scene was stored in advance in the storage unit 161d. For example, if the above-mentioned scene 1 is played as a lighting control in addition to the sound output from speaker groups 1 and 2, desk group 1 will have the effect of increasing the efficiency of concentrated work by lighting as described in Example 1. And the effect of the sound of a babbling stream, which tends to increase the efficiency of concentrated work, will be superimposed. Therefore, due to the synergistic effect of the superposition, the zone of the desk group 1 can be changed to an area where the efficiency of concentrated work can be improved to a greater degree.

The sound of a babbling stream has characteristics similar to so-called white noise or brown noise, which has intensity in all frequency ranges. When this characteristic is expressed graphically as a Fourier transform spectrum of frequency versus intensity, it can be expressed as a graph of a Fourier transform spectrum that does not have intensity in the entire frequency domain, for example, a Fourier transform spectrum of frequency versus intensity of a specific scale note on the piano. In comparison with the graph of , it can be mentioned that the frequency characteristics of the sound in the graph are broad. Sounds with this characteristic are noises that can reduce the efficiency of focused work that come from locations other than desk group 1 with various frequencies, compared to sounds that tend to have no intensity in the frequency domain, e.g. It has a remarkable effect of easily canceling noises, speaking voices, etc. Therefore, a worker working in desk group 1 will have difficulty hearing external noise. Therefore, the zone of desk group 1 can be made into an area where it is easier for workers to concentrate on their work and become absorbed in their work.

As the sound content that can improve the efficiency of concentrated work, it is preferable to use something similar in characteristics to the above-mentioned white noise or brown noise, but the present invention is not limited to this. For example, it may be music that mainly consists of natural environmental sounds such as the chirping of birds, the rustling of leaves in the forest, or the sound of ocean waves, or it may be music that is mainly composed of electronic sounds that are synthesized in waveforms by a music synthesizer or the like. Also good. The sound content may be a recording of natural sounds as is, a composition composed by a human, or a composition composed by a computer algorithm, AI, or artificial intelligence. The sound content may be a mixture of the various types of sounds mentioned above.

On the other hand, in the area where desk group 2 exists, scene 1 will be played in addition to the output of sound content recorded with jazz and bossa nova music, so as explained in Example 1, the color temperature will be adjusted. The effect of promoting a feeling of relaxation and smooth communication between multiple people based on low illumination light irradiation is superimposed with the effect of promoting a feeling of relaxation and smooth communication between multiple people due to jazz and bossa nova music. . Therefore, due to the synergistic effect of the superposition, the zone of the desk group 2 can be made into an area where workers can relax in each level and smooth communication among multiple people can be facilitated in each level.

Compared to the aforementioned white noise and brown noise, jazz bossa nova music has a characteristic that the frequency characteristics of the sound in the graph of the Fourier transform spectrum of frequency versus intensity are not broad. This is because instruments such as the piano, saxophone, and bass that primarily play jazz and bossa nova play a specific single scale, namely do re mi fa so la si do and its chromatic scales. This is due to the fact that it is used in a state where it is strictly tuned to output. Therefore, the above-mentioned noise canceling function against external noise tends to be poor, but in the first place there is little need for a noise canceling function in a co-creation space where the intention is to relax or communicate with multiple people. , even if the noise canceling function is reduced, no major harm will occur.

Furthermore, jazz, bossa nova, and the like are sound contents that are often provided in cafes and relaxation facilities, and are frequently used to promote relaxation and smooth communication among multiple people. Therefore, as is clear from this, by using these sound contents, workers can feel a sense of relaxation and peace, and smooth communication can be realized.

Note that it is preferable to adopt sound content that is close to the characteristics called jazz or bossa nova as the sound content that can promote a feeling of relaxation and smooth communication among multiple people, but this is not particularly limited. For example, classical music, healing music, natural environmental sounds, etc. may be used as sound content that can promote relaxation and smooth communication among multiple people. Such sound content may be a recording of natural sounds as is, a composition composed by a human, or a composition composed by a computer algorithm, AI, or artificial intelligence. The sound content may be a mixture of the various types of sounds mentioned above.

As is clear from the above description, it is preferable that the lighting control and the sound control are linked, and it is more preferable that the purposes of the lighting and sound contents that can be predominantly provided to each desk group are the same. By doing so, the effects of the main idea intended by each desk group can be superimposed to create a synergistic effect, and the effects of the main idea intended by each desk group can be made remarkable.

Note that when lighting control and sound control are linked, their operations do not need to be strictly synchronized; for example, the start time or end time of lighting scene switching and the start time or end time of sound content switching are different. Even if there is some deviation, the above-mentioned effects will not be lost. In addition, if such a discrepancy occurs, the time difference between the start time or end time of the lighting scene change and the start time or end time of the sound content change may be any amount of time, but within 30 minutes. The time is preferably within 10 minutes, more preferably within 1 minute, and most preferably within 10 seconds. If the time difference is within 30 minutes, the layout change can be accomplished much faster and with less effort than a layout change that typically involves transporting and reinstalling fixtures and furniture.

<Evaluation results of spatial illumination and volume in scene 1>
Next, the results of a test of the illuminance and sound volume of the space in scene 1 will be explained. FIG. 9 shows information on the irradiation light emitted by each lighting device 103, 105 and the sound outputted by each speaker 109a to 109d when sound is output and scene 1 is reproduced in Example 2. It is a schematic diagram explaining the information of. Further, FIG. 10 shows that in the ABW office 120 of the second embodiment, when the lighting scene 1 is played, the sound of a babbling stream is played from the speaker group 1, and jazz or bossa nova music is played from the speaker group 2, A graph showing the results of one test example when the illuminance and sound volume of the space were measured using an illumination meter (CL-200: Konica Minolta) and a sound level meter (SD-2200: FUSO) arranged across desks D12 to D03. It is. Note that in FIG. 10, y1 is a function related to illuminance, and y2 is a function related to volume.

As shown in FIG. 10, in this test example, the illuminance and sound volume of the passage provided between desk group 1 and desk group 2 are the lowest. Then, different illumination light is irradiated and different sound contents are reproduced on both sides of the passage. Furthermore, in desk group 1, it is possible to realize illumination light in which the illuminance locally increases rapidly on the desk surface. Furthermore, in desk group 1, sound content that promotes people's concentration is reproduced at high volume, and in desk group 2, sound content that gives people a feeling of relaxation and peace is output in desk group 1. The output is at about half the volume. Therefore, in this test example, the peripheral area of desk group 1 and the peripheral area of desk group 2 can be clearly separated (divided), and excellent zoning can be achieved. In addition, the lighting and sound content reproduced in the area around desk group 1 and the area around desk group 2 make the area around desk group 1 an excellent concentration space where people can easily concentrate on their work. On the other hand, the area around desk group 2 can be made into an excellent co-creation space where people can feel particularly relaxed and where multiple people can communicate.

<Preferable configuration when adopted in the second embodiment and effects derived from the configuration>
As described in the second embodiment, in the environmental control system 110, the group information and control scene information of the plurality of devices 103 and 105 may be stored in the storage unit 161d. Further, the control scene information may include information about a scene that is associated with the group information and includes illumination light of a group where the spotlight 105 is turned on and illumination light of a group where the spotlight 105 is not turned on. The control device 161 further includes a speaker 109 for transmitting sound toward the viewing target area, and the control device 161 includes a sound signal transmitting section 161c for transmitting sound content to the speaker 109, and a sound signal transmitting section 161c for transmitting sound content to the speaker 109, and a sound signal transmitting section 161c for transmitting sound content to the speaker 109. It may include a storage unit, and a sound control unit for controlling at least one of a sound content control schedule and a volume. Then, the frequency characteristics of the sound content that reaches the visual target area of the spotlight 105 from the group where the spotlight 105 is lit are different from those of the sound content that reaches the visual target area of the spotlight 105 from the group where the spotlight 105 is not lit. It may be different from the frequency characteristics.

According to this configuration, zoning can be carried out significantly, and the intended effect can be made noticeable in each zone. More specifically, it is preferable because the zoning effect, that is, the functions of each zone, such as areas where it is easy to concentrate and areas where it is easy to relax, can be more clearly divided. At this time, the frequency characteristics of the sound content in each zone are obtained by performing fast Fourier transform on time-series data of audio recorded with known microphones and sound collection equipment, and by comparing them, the frequency characteristics of the sound content in each zone are determined. It is possible to determine whether or to what extent the contents are different.

Furthermore, the spectral width in the fast Fourier transform of the sound content that reaches the visual target area of the spotlight 105 from the group where the spotlight 105 is lit is the same as the spectrum width in the fast Fourier transform that reaches the visual target area of the task light from the group where the spotlight 105 is not lit. It may be wider than the spectral width in fast Fourier transform of sound content.

According to this configuration, the area where the spotlight 105 is lit can be made into an area where people can more easily concentrate.

Then, at least one of the sound content control schedule and the volume may be controlled using at least one of the information from the detection section and the information from the detection information analysis section.

As an example, to give a more detailed explanation of two of these cases, for example, in the above-mentioned Embodiment 1, a known omnidirectional camera 180 whose perspective view is shown in FIG. may be installed. Then, as shown in the control flowchart shown in FIG. 12(a), when the environmental control system 10 is installed in the ABW office 20 and is activated, the control device 61 receives the information from the omnidirectional camera 180 wirelessly or by wire in step S1. Based on the signal, it may be determined whether the number of people in the ABW office 20 is greater than or equal to a predetermined number.

If a negative determination is made in step S1, the process proceeds to step S2, and scene 1 shown in FIG. 2 is reproduced. If an affirmative judgment is made in step S1, the process proceeds to step S3, and scene 3 shown in FIG. After that, the control may return and steps S1 and subsequent steps may be repeated.

According to this control, for example, on days when the need for concentration spaces is high, such as on busy days in the office, Scene 3 can be automatically reproduced, and the number of seats in the office concentration space can be increased from 8 to 14 seats, allowing workers to By meeting the needs of people for a concentrated space, it becomes easier to improve the work performance of workers and organizations as a result.

In the first embodiment described above, the storage unit 61c of the control device 61 further includes a storage unit in which light control information regarding dimming control for a predetermined period (date and time) of each spotlight 5 and each base light 3 is stored.
