Description

Environmental control system

This disclosure relates to an environmental control system.

ABW (Activity Based Working) offices are emerging as a result of work style reforms. In the ABW office, for example, when a worker wants to do intensive work alone, when multiple people want to do group work, when he wants to take a break or relax, the type and amount of work that changes from moment to moment, or the emotions of the worker himself. It is an office that streamlines the performance of workers and organizations by allowing workers to select spaces with different design objectives in response to motivated intentions. As a method of creating a space having a different design purpose, for example, as described in Patent Document 1, a means of creating a space having the purpose of improving the efficiency of concentrated work by using furniture and furniture and performing zoning is known.

Japanese Unexamined Patent Publication No. 2017-131572

Ideally, the ABW office should undergo continuous zoning changes according to the fluid work performance of workers and organizations and the needs of each space. For example, the zoning of the booth-type furniture and furniture described above can be changed by changing the arrangement and number of furniture and furniture in response to the excess or deficiency of the utilization rate even after installation. However, while the work performance of workers and organizations and the needs for each space can occur even in cycles such as hourly, daily, and monthly, the work of transporting and re-installing furniture and furniture, storing in warehouses, etc. is described above. It is difficult to carry out continuously in this cycle in view of the labor and labor, and there is a problem as a means for realizing the ABW office in terms of flexibility of design change.

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

In order to solve the above problems, the environmental control system according to the present disclosure includes one or more task lights for illuminating a visual target area in a room, and a plurality of task lights for illuminating a wider area than the visual target area in the room. The control device includes a base light and a control device, and the control device includes a dimming toning signal transmitter that transmits a signal for controlling dimming and toning to the task light and the base light, and a preset task. It has a storage unit that stores position information of lights and base lights, and device identification information, and the control device uses the information stored in the storage unit to transmit signals from the dimming and toning signal transmission unit. It is possible to execute one or more group controls that execute dimming / coloring control of at least one task light and a plurality of base lights in conjunction with each other, and at least one task light is used for one or more group controls. Control to control at least one task light and a plurality of base lights so that when the light is turned on, the light amount of the base light installed in the vicinity area is equal to or less than the light amount of the base light in the area where the task light is not turned on. Is included.

The amount of light of the base light installed in the vicinity area may be zero. Further, the base light installed in the vicinity area refers to one or more base lights capable of predominantly illuminating the visual target area illuminated by the task light, including the base light closest to the lit task light. It shall be. Further, the base light in the area where the task light is not lit refers to one or more base lights which cannot predominantly illuminate the visual target area illuminated by the lit task light.

Here, the requirement of "dominantly illuminating" reaches the largest luminous flux amount of all the installed base lights with respect to the visual target area illuminated by the lit task light. The ratio of the luminous flux that reaches the visual 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) is defined as the origin luminous flux ratio, and is half of the origin luminous flux ratio. When the value is defined as the effective luminous flux ratio, the ratio of the luminous flux amount reaching the visual target area to the total luminous flux amount emitted is satisfied in the case of the base light having the effective luminous flux ratio or more and the origin luminous flux ratio or less. ..

Next, we will explain whether or not the requirement of "dominant lighting" is satisfied with a concrete example so that it is easy to understand. 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 plate-shaped object having a size of 1218 mm × 78 mm and the upper surface of a plate-shaped object having a size of 700 mm × 1200 mm have been defined as a light source unit. The distance between the light source unit and the light receiving unit was 1800 mm. It should be noted that these substantially reflect the size and light distribution of the light source and the work desk used in the examples described in the present specification, and the distance between the upper surface of the desk and the light source unit.

FIG. 14 shows a state in which the center coordinates of the light source unit and the light receiving unit are matched as shown in FIG. 13, and the energy reaches the light receiving unit when the position coordinates of the light source unit are offset in the X-axis direction from that state. It is a graph which shows the ratio of the quantity. The energy rate reaching the desk surface on the vertical axis indicates the luminous flux ratio indicating the percentage of the luminous flux reaching the desk surface, which is the visual target area, when the total luminous flux emitted from the light source unit is 100%. .. In this specific example, as shown in FIG. 14, the origin luminous flux ratio representing the luminous flux ratio when the base light is present at the position coordinates of x = 0 mm and y = 0 mm is 7.1%. As a result, the effective luminous flux ratio is recognized as 7.1 × 0.5 = 3.55%. From this, in the base light that satisfies the requirement of "dominantly illuminating", the ratio of the luminous flux reaching the desk surface to the total luminous flux emitted is required to be 3.55% to 7.1%. From this simulation result, for example, the following can be mentioned.

In the case of this specific example, in a 1218 mm × 78 mm base light provided at a height position of 1800 mm from a 700 mm × 1200 mm visual target area, the amount of light flux reaching a certain visual target area out of the total luminous flux emitted from the base light. A base light having a ratio of 3.55% to 7.1% is a base light that predominantly illuminates a certain visual target area. In other words, if the ratio of the luminous flux reaching a certain visual target area to the total luminous flux emitted from the base light is less than 3.55%, it is a base light that cannot predominantly illuminate a certain visual target area. is there. The total luminous flux of the base light can be measured by using a known measuring / analyzing means such as an integrating sphere and a spectrophotometer, and the luminous flux reaching the visual target region can be measured / analyzed by a known measurement / analysis such as an illuminometer. It can be measured by means. In addition, 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 visual 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 size and light distribution of the light source in the simulation setting conditions and executing the simulation, a base light that predominantly illuminates a certain visual target area. It is possible to determine whether or not it is, and by grasping the actual size and illuminance using a known illuminometer or the like, it is possible to determine whether or not a certain base light is a base light that predominantly illuminates a certain visual target area. It can be judged.

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.

Hereinafter, embodiments according to the present disclosure will be described in detail with reference to the accompanying drawings. When a plurality of embodiments and modifications are included in the following, it is assumed from the beginning that a new embodiment is constructed by appropriately combining the characteristic portions thereof. Further, in the following examples, the same components are designated by the same reference numerals in the drawings, and duplicate description will be omitted. In addition, the plurality of drawings include schematic views, and the dimensional ratios such as length, width, and height of each member do not always match between different drawings.

In addition, when the word "abbreviation" is used in this specification, it is used in the same meaning as the word "roughly speaking", and the requirement "abbreviation" is used if the person looks like "abbreviation". It is filled. For example, the requirement of a substantially circular shape is met if a person looks roughly circular.

[Example 1]
FIG. 1 is a drawing showing an embodiment of a layout of a plurality of work desks D01 to D14 possible in an ABW office 20 as an example of a room in which the environmental control system 10 according to the first embodiment of the present disclosure is installed. There are layouts when multiple work desks D01 to D14 are viewed from above, and the layout of the base light 3, the duct rail 4 for energization, and the spotlight 5 attached to the ceiling of the ABW office 20 is shown in the work desks D01 to D01. It is a layout layout drawing described in the form of superimposing 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 the desk group 1. Twenty-eight LED dimming toning base lights (for example, NNLK41515 + NNL4600EXDK9: Panasonic) as ambient lighting for lighting were installed at equal intervals, and duct rails 4 for energization were installed in three rows in the vicinity thereof. Specifically, a total of 14 work desks D01 to D14 are arranged in 4 cases, and 3 duct rails 4 for energization are placed in the vicinity of 3 rows of work desks D01 to D14 out of 4 work desks D01 to D14. They were arranged so as to extend in a direction substantially parallel to the extending direction of the row.

Furthermore, a total of 14 LED dimming spotlights (for example, NTS05121W: Panasonic) 5 as an example of task lights were installed on each duct rail 4. At the same time, 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 have a one-to-one correspondence, and each spotlight 5 illuminates the central portion of the corresponding work desks D01 to D14. The installation position and installation direction of the spotlight 5 were adjusted.

The 28 base lights 3 and 14 spotlights 5 are a multi-manager (for example, NQ51101: Panasonic), an LS / PD signal conversion interface (for example, NK51111: Panasonic), and a PD / adjustment as an example of a control device. It was sequentially connected to an optical signal conversion interface (for example, NK51012: Panasonic) and PiPit + separate cell control A type (for example, NQ23171Z: Panasonic) via a dimming signal line. In addition, 7 spotlights 5 were paired with each of the prepared PiPit + separate celcon A type.

Next, using the operation application of the multi-manager, the position information of each base light 3 is stored by the mapping work of 28 base lights 3, and as shown in FIG. 1, 12

base lights

3 and 8 units are stored. Spotlight 5 is set as a lighting device belonging to

lighting group

1, 4 base lights 3 are set as lighting devices belonging to lighting group 2, and 12

base lights

3 and 6 spotlights 5 are illuminated. It was set as a lighting device belonging to group 3. Further, as shown in FIG. 2, four scenes were set for each of the lighting groups 1 to 3, and the color temperature and dimming rate values were set for each groove in each scene.

Here, the setting of each scene can be easily executed using an information terminal in which the application of the existing scene setting is installed, for example, a smartphone, a tablet, a remote controller, or the like. Then, each scene was actually reproduced. Specifically, when the blind curtain of the window of the ABW office 20 was closed and the scene 1 was reproduced using the operation unit 64 (see FIG. 3), the desk group 1 and the desk group 2 were divided in appearance. .. Subsequently, when other scenes such as

scenes

3 and 4 were sequentially reproduced using the operation unit 64 (see FIG. 3), each scene was switched in about a few seconds.

The desk group 1 in scene 1 had a non-uniform illuminance distribution in which the illuminance was high only in the central portion of the work desks D07 to D014, and the illuminance decreased as the distance from the central portion increased. In addition, the illuminance of the floor and walls around the work desk was low, and the space had a low sense of brightness. On the other hand, in the desk group 2 of the scene 1, the illuminance of the work desks D01 to D06 has a higher uniform illuminance distribution than that of the desk group 1, and the illuminance of the floor and walls around the work desk is also high, and the feeling of brightness is high. It was a space.

At this time, when the worker is seated in the desk group 1, the illuminance is high only in the central part of the work desks D07 to D014 that the worker should pay more attention to, so that the cognitive noise factor of the peripheral visual field is reduced, so that the worker It is easy to immerse yourself in the work and improve the efficiency of intensive work. Further, in this method, since the dimming rate of the base light 3 is set low, the visibility of the peripheral visual field such as the wall or the floor is lowered, so that the work desks D07 to D014 and the work are more absorbed. It is easy to increase the effect. In addition, because the dimming rate of the base light 3 is set low, the worker working in the desk group 1 may not be able to see the facial expression well when viewed by other workers from the outside, or may be on the face. It's hard to talk to because it looks moody because of the shade. That is, the worker working in the desk group 1 is likely to be talked to by another worker and the probability that the work is interrupted is likely to decrease, and as a result, the efficiency of the intensive work is likely to be improved. From the above, when the scene 1 is reproduced, the desk group 1 is a space that easily functions as a concentrated space. On the other hand, in scene 1, the desk group 2 is a space that easily functions as a co-creation space because the color temperature is low and it is easy to relax and increase the amount of communication between a plurality of people.

Desk group 1 and desk group 2 have very different spatial illuminance distributions. In particular, the desk group 1 is characterized in that the illuminance of the floor and walls around the work desk is lower, which causes a high sense of division of the space in appearance between the two desk groups. Further, since the color temperature of the illuminations of the desk group 1 and the desk group 2 are significantly different from each other, the appearance of the space is highly divided. From the above, it has a cognitive zoning effect that divides the space without using furniture or furniture. As for the zoning effect, the larger the difference in the illuminance distribution and the color temperature of each group, the easier it is to enhance the effect.

Further, the desk group 1 and the desk group 2 have different work contents to be urged to the workers. For example, the desk group 1 of this embodiment promotes intensive work, and the desk group 2 promotes relaxation and communication. Therefore, only in appearance. In addition, there is a difference in the functional usage of each space, so this effect also contributes to the zoning effect.

And when zoning is performed by this method, switching of each scene is completed in a few seconds, and as a result, it is possible to change the layout of the office in a few seconds. For example, on a busy day in the office where the need for concentrated space is high, switching from scene 1 to scene 3 will increase the number of seats in the central space in the office from 8 to 14 to meet the needs for concentrated space for workers. As a result, it becomes easier to improve the work performance of workers and organizations. Alternatively, in the case of a fallow day, if the scene 4 is switched, the number of seats in the concentrated space becomes 0 and the co-creation space becomes 14 seats, which has the effect of reducing the stress of the organization and increasing the amount of communication. Furthermore, it is possible to adjust the number of seats in the concentrated space in the afternoon during the lunch break by referring to the utilization rate of the concentrated space in the morning of one day. According to this method, active zoning that changes the layout in cycles such as hourly, daily, and monthly, which is difficult with the above-mentioned method using furniture and furniture, is possible. In the conventional office scene, it is common to illuminate areas such as work desks and aisles with high uniformity of color temperature and illuminance distribution. On the other hand, since the present application uses such a lighting method and a control method, it is possible to realize a remarkable effect that could not be predicted by the conventional knowledge of lighting, especially in the ABW office scene.

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 has an operation unit 64 in addition to a control device 61 composed of a base light 3, a spotlight 5, and a multi-manager, and the control device 61 includes a control unit 61a. , A dimming toning signal transmitting unit 61b and a storage unit 61c are included. 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). Further, 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 a program or the like stored in advance in the storage unit 61c. In addition, the non-volatile memory stores a control program, a predetermined threshold value, and the like in advance. In addition, the volatile memory temporarily stores the read program and processing data. The storage unit 61c stores position information and device identification information regarding each of one or more preset spotlights 5 and the plurality of baselights 3. Further, the storage unit 61c stores dimming and toning data that reproduces the above-mentioned scenes 1 to 4. In the first embodiment, the eight work desks D07 to D014 belong to the desk group 1, and the six work desks D01 to D06 belong to the desk group 2, but the work desks belong to the desk group 1 and the desk group 2. The number of is not limited to the case of Example 1. Further, the number of lighting groups is not limited to three as in the first embodiment, and any number of lighting groups of two or more may exist. Next, the position information, the device identification information, and each configuration included in the environmental control system 10 will be described in detail.

(About information)
<Location information>
The position information may be information similar to the absolute value of the coordinates such as the actual position in the space, or the relative positional relationship based on a certain spotlight, a base light, or an existing pillar in the space. Information is also acceptable. Further, the position information stored in the storage unit 61c does not have to be able to completely reproduce the position and positional relationship of the spotlight and the base light actually installed, and may be information that can reproduce (define) only a part of the position information. Further, the position information may be recorded in the storage unit by input by the user, or may be recorded by AI or a computer algorithm. Further, the position information may be set / recorded while referring to the drawing data separately stored in the storage unit or the like, or being associated with the drawing data. Further, the location information does not have to be given or associated with all the devices included in the environmental control system, and may be appropriately selectable according to the user's circumstances.

<Device identification information>
The device identification information is information that can identify a device of a spotlight or a base light, and is composed of, for example, a manufacturing number, a MAC address, an IP address, a product number, and the like. The device identification information is used in the environment of each device, such as when setting / recording the above-mentioned position information, groups, and scenes, or when individually setting / recording the output parameters (color adjustment rate, dimming rate, etc.) of the device. It is used in a control system so that different devices are not unintentionally identified as the same. The device identification information does not have to be assigned or associated with all the devices included in the environmental control system, and the device to be assigned or associated can be appropriately selected according to the user's circumstances.

(Specific aspects of each configuration)
<Task light>
The device form of the task light is not particularly limited, and as the task light, in addition to the spotlight 5 described above, a desk light, a downlight, etc. can be adopted, but the task light is specified as a spotlight. It is preferable that the light distribution is controlled so as to collect the light in the area because it is easy to control the illumination range of the work desk. More specifically, the spotlight 5 may have a form in which a perspective view is shown in FIG. 4, that is, a structure in which a person adjusts the irradiation direction of the spotlight 5 by applying an external force, and FIG. 5A may have a structure. , (B) shows a perspective view, that is, a structure in which the irradiation direction of the spotlight 5 can be automatically adjusted to any of the downward directions by freely rotating the two rotation axes with a motor or the like with a remote controller. It may be a thing. If at least one spotlight 5 is shown in FIGS. 5A and 5B, and the emission direction of the illumination light can be changed in any direction at the installation position, the work desk in the longitudinal direction in the concentrated space The degree of freedom of the gap between the work desks can be increased, and the degree of freedom of the gap between the work desks in the width direction in the concentrated space can be increased, so that the degree of freedom of layout of the concentrated space can be increased. Further, when at least one spotlight 5 has the form shown in FIGS. 5A and 5B in which the irradiation direction of the spotlight 5 can be freely adjusted by a remote controller, the spot can be safely spotted from the ground without using a stepladder or the like. The irradiation direction of the light 5 can be adjusted. Further, as described above, it is preferable to use a dimming toning type spotlight as the task light.

The task light is a light for improving work efficiency of a worker's work, for example, a personal computer operation work, a writing work, a reading work, etc., and is a lighting that is selectively illuminated on a visual target area of a work desk. The visual target area is an area that can be generally seen when working on a work desk. For example, when a personal computer (hereinafter, simply referred to as a personal computer) is placed behind the center of the work desk for operation. The central part of the work desk is the center of the visual field area. At this time, changes in the visual object due to physiological factors or accidental changes in posture or line of sight are not taken into consideration, that is, looking up at the ceiling for temporary thinking or stretching, moving the line of sight to the wall, or sneezing. Events such as shifting the line of sight to the floor due to sneezing or coughing, or shifting the line of sight due to someone talking to them are not considered as significant changes in the visual target area on the work desks D01 to D14.

The illumination range of the task light is preferably limited to a part of the visual target area, and for example, the illumination range is preferably 30% to 90% with respect to the area of the work desk. The illumination range of the task light is not particularly limited, but is preferably substantially circular or substantially polygonal. By doing so, the brightness of the visual target region becomes brighter than the brightness of the region other than the visual target region, and the cognitive noise of the peripheral visual field is reduced. Therefore, the worker's consciousness is directed toward the work desk side, and it is easy to improve work efficiency.

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

<Base light>
The base light is a lighting for increasing the brightness of the room, and is a lighting that uniformly illuminates the room. The light distribution of the base light is preferably wider than that of the spot light in order to uniformly illuminate the room. The color temperature of the base light is not particularly limited. The base light is preferably a dimming toning type. The device form of the base light is not particularly limited, and any device such as a ceiling light, a line light, a pendant light, a spotlight, and a light bar 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 / toning control. The device form of the control device 61 is not particularly limited, but as the device form of the control device 61, for example, the lighting control device and the control application of the lighting control device described in the first embodiment can be preferably adopted. The device control application may be installed in another terminal such as a personal computer or a smartphone in addition to the tablet illustrated in FIG. 3, which is preferable because it is easy for the user to 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 the operation terminal such as a tablet, and as shown in FIG. 6, the environmental control system. The control device 71 of the 70 may be a terminal or device different from the operation terminal such as the tablet 72. Here, the control device 71 may have its housing embedded in the ceiling or wall surface, or may be stationary on the ground or a storage shelf. Further, the control device 71 may be controlled by wire communication with an information terminal such as a 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 signal line for communication and a wireless LAN access point. Further, at this time, the tablet 72 or the like does not have to directly communicate with the spotlight 5 or the base light 3. At this time, information on the positions and control conditions of the appliances constituting the environmental control system 70, such as mappings, scenes, groups, and control schedules set by using the operation unit 75 of the tablet 72, is transmitted to the control device 71, and the control device It may be recorded in the storage unit 76 of 71. In this case, the intended environmental control can be performed even when the power of the tablet 72 is turned off or the tablet 72 is stored in a place outside the communication range with the spotlight 5 and the base light 3. Further, the control device 71 does not have to have a user interface for operation such as a liquid crystal display. In this case, the control device 71 is preferable because it is easy to miniaturize, and the ease of installation and the designability are improved. Although not particularly shown in FIG. 6, an operation terminal such as a tablet 72 may have a storage unit. Further, the environmental control system 70 shown in FIG. 6 is a modification of the

environmental control systems

10 and 110 shown in FIG. 3 or FIG. 8 described later, but can be realized and conceived easily by other than the environmental control system 70 shown in FIG. It is clear that there are many aspects of environmental control systems.

<Dimming and toning signal transmitter>
The dimming toning signal transmission unit 61b is a part that transmits a dimming toning signal to the task light and the base light to execute at least one of dimming and toning, and is included in the control device 61. is there. The signal format is not particularly limited, and any known dimming signal, Wi-Fi, Bluetooth (registered trademark), or the like can be used. In the above-mentioned dimming and toning control, the dimming and toning control of the digital control method has been described, and the control method for transmitting a digital signal (PDCL) from the light control has been described. Here, in this control method, in addition to the power supply line, wiring of a signal line for digital control is required. In this digital control, since detailed information can be communicated, it is possible to perform control using a large amount of information, and control by a wireless signal is also included in this method.

However, when performing dimming and toning control, a phase control method may be adopted, or dimming control may be executed by directly adjusting the power to the lighting equipment. In this method, since the power supply current to the lighting equipment is directly controlled, it is easily affected by voltage fluctuations, but it is not necessary to draw a dedicated signal line separately, so that it is excellent in workability. Alternatively, when performing dimming and toning control, a signal line method may be adopted, and a dimming signal (duty signal) is sent from the light control, and the brightness of the light emitting part such as an LED is adjusted by the power supply unit on the device side. You may control it. This method requires wiring of a dimming signal line in addition to the power supply line, but since it is not easily affected by the wire voltage, smooth dimming control without flicker is possible. It should be noted that the control of only ON / OFF of the task light and the base light is also included in the dimming control.

<Memory>
Any known device may be adopted as the device constituting the storage unit. Further, unlike the configuration shown in FIG. 3, the storage unit does not have to be incorporated inside the control device. For example, an information terminal different from the information terminal including the control device, for example, a smartphone, a tablet, a personal computer, or the like. Alternatively, it may be composed of 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 may be rewritten and set by the machine in the cloud or AI.

<Group information of multiple devices>
Group information of a plurality of lighting devices is managed by, for example, an application. Grouping may be set and saved by operating a tablet terminal, for example. The same command is sent to the grouped devices all at once, and for example, the same dimming and toning control is applied. Regarding dimming and toning control of a plurality of grouped devices, that is, group control, signal delay is allowed, and variation in device operation is also allowed. For example, the permissible variation in device operation is within 30 minutes, more preferably within 10 minutes, even more preferably within 1 minute, most preferably within 10 seconds, and a signal or signal that falls within this range. The instruction delay is included in the behavior of the grouped devices. When the operation variation of the equipment is within the above time, it is preferable because the layout change can be easily achieved quickly and labor-savingly as compared with the layout change involving the transportation and re-installation of general furniture and furniture. The group setting may be included as a function of the application that operates the control device, but it is not always defined by the name of "group". It is preferable to set a group in the application for operating the control device or the storage unit included in the control device because it is easy for the user to manage and change the lighting and its control parameters.

<Control scene information>
It is a very complicated task for the user to set and reproduce control parameters such as dimming rate and toning rate of each lighting device for a plurality of lighting devices. This is because a general ABW office uses 10 or more or 30 or more lighting devices, and in many cases 100 or more. Therefore, a method of collectively storing and managing control parameters of a plurality of lighting devices in a storage unit is known, and this is referred to as a scene in the present application. By doing so, not only is it easy for the user to manage the conditions of the control parameters for a plurality of lighting devices, but also those conditions can be instantly reflected in the plurality of lighting devices at a desired timing (hereinafter, hereafter. (Referred to as regeneration) is also easy, which is preferable. Further, the user can instantly switch between two or more intended setting conditions by storing a plurality of types of scenes in the storage unit in advance. The settings of each scene may be set in any way according to the specification needs. For example, unlike the example shown in FIG. 2, the dimming rate of 10 base lights in scene 1 is set to 100%. It may be stored in the storage unit, and further, the dimming rate of the above-mentioned 10 base lights may be set to 30% in the scene 2 and stored in the storage unit. Then, when the scene 1 is played back, the dimming rate of the 10 base lights is instantly set to 100%, and when the scene 2 is played back from this state, the 10 base lights are instantly set. The dimming rate of the above may be set to 30%. In this way, it is preferable to realize dimming control of a large number of lighting devices in a much shorter time and with less labor than the work of resetting the dimming rate of 10 lighting devices each time. The scene setting may be included as a function of the application that operates the control device, but it is not always defined by the name of "scene". Further, as the setting of each scene, the scenes of

groups

1 and 2 may be set as follows. For example, in scene 1, group 1: dimming rate 0% and group 2: dimming rate 50% may be set, and in scene 2, group 1: dimming rate 50%, group 2: dimming rate 0. May be set to%. By setting the scene in this way, it is possible to instantly exchange a zone where workers can easily concentrate and a zone where workers can easily relax and communicate with other workers, and when the scales of the two zones are different. In addition, the scale of each zone can be changed instantly according to needs. Regarding dimming and toning control of a plurality of devices in a scene, that is, group control, signal delay is allowed, and variation in device operation is also allowed. For example, the permissible variation in device operation is within 30 minutes, more preferably within 10 minutes, even more preferably within 1 minute, most preferably within 10 seconds, and a signal or signal that falls within this range. The instruction delay is included in the behavior of multiple devices that are scened.

(Example 1 configuration and action effect)
The control in the environmental control system 10 of Example 1 and the specific aspects of each configuration have been described above. In this item, the essential configuration of the environmental control system 10 and its action and effect, and the configuration preferable to adopt and its action and effect, which have been clarified from the above description, will be described.

<Indispensable configuration and the action and effect derived from that configuration>
The environmental control system 10 includes one or more spotlights (task lights) 5 for illuminating the visual target area (near the center of the upper surface of the work desks D01 to D14) in the ABW office (room) 20, and the ABW office. A plurality of base lights 3 for illuminating a region wider than the visual target region within 20 and a control device 61 are provided. Further, the control device 61 includes a dimming and toning signal transmission unit 61b that transmits a signal for controlling dimming and toning to the spotlight 5 and the base light 3, and a preset spotlight 5 and the base light 3. It has a storage unit 61c for storing the position information and the device identification information. Further, the control device 61 uses the information stored in the storage unit 61c to adjust the dimming / adjusting of at least one spotlight 5 and the plurality of base lights 3 by the signal transmitted from the dimming / toning signal transmitting unit 61b. It is possible to execute one or more group controls that execute the color control in conjunction with each other. Then, in the group control of one or more, when eight spotlights 5 belonging to the group 1 as an example of at least one spotlight 5 are turned on, as an example of the base light 3 installed in the vicinity region thereof. The light intensity of the eight baselights 3 closest to each of the eight spotlights 5 is 20 baselights other than the eight baselights 3 as an example of the baselights in the area where the task light is not lit. Controls are included to control the eight spotlights 5 and the 28 baselights 3 so that the amount of light is 3 or less.

Therefore, as described 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 people concentrate on the area near the spotlight 5 that is lit. It can be an easy area.

<Multiple configurations that are preferable to select and the effects derived from each configuration>
Further, the storage unit 61c may store information (group information) of the lighting groups 1 to 3 of the plurality of

devices

3 and 5. Then, the information of the lighting groups 1 to 3 of the plurality of

devices

3 and 5 may include the information of a plurality of groups (lighting groups 1 and 3) in which one or more spotlights 5 and one or more base lights 3 are mixed. Good. Further, as in the control of the scene 1 of FIG. 2, when one or more spotlights 5 are turned on, the amount of light of a part or all of the baselights 3 included in the same lighting group 1 is the amount of light of the spotlight 5. A base light 3 included in a lighting group 2 not included, or a part or all of a base light included in a lighting group 3 having one or more spotlights 5 but no spotlight 5 lit. It 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 a plurality of lighting devices included in the same lighting group 1 is broadened with respect to the area illuminated by the lighting devices belonging to the other groups. Can be darkened. 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 in which the spotlight 5 is lit into a space in which people can concentrate more easily. ..

Further, the control scene information may be stored in the storage unit 61c. Further, 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 one or more second scenes (FIG. 2) in which the spotlight 5 is not lit. The information of the fourth scene of 2) may be included. Further, in a plurality of scenes in which one or more spotlights 5 and a plurality of baselights 3 can be realized, they are installed in a region near the spotlights 5 in the first scene (first to third scenes in FIG. 2). The light intensity of the base light 3 is controlled to be equal to or less than the light intensity of the base light 3 installed in the vicinity of the spotlight 5 in the second scene (fourth scene in FIG. 2), that is, the first scene (FIG. 2). The first to third scenes) and the second scene (fourth scene in FIG. 2) may be included.

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

Further, the storage unit 61c may store the group information and the control scene information of the plurality of

devices

3 and 5. Further, as shown in the first scene of FIG. 2, the control scene information is associated with the group information, and the group in which the spotlight 5 is lit (lighting group 1 in FIG. 2) and the group in which the spotlight 5 is not lit (FIG. 2). Information on the scene generated when the lighting groups 2) of 2 are adjacent to each other may be included.

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

devices

3 and 5. Further, as shown in the first scene of FIG. 2, the control scene information is associated with the group information, and the illumination light and the spotlight 5 of the group in which the spotlight 5 is lit (illumination group 1 in FIG. 2) are not lit. Information on the scene including the illumination light of the group (illumination group 3 in FIG. 2) may be included. Further, the amount of light per unit area from the base light 3 included in the group in which the spotlight 5 is lit (illumination group 1 in FIG. 2) to reach the visual target area of the spotlight 5 is the group in which the spotlight 5 is not lit (lighting group 1 in FIG. 2). The amount of light from the base light 3 included in the illumination group 3) of FIG. 2 to reach the visual target area of the spotlight 5 may be controlled to be less than or equal to the amount of light per unit area.

According to this configuration, the visual target area can be focusedly illuminated by the light from the spotlight 5 in the concentrated space. Therefore, it is possible to more effectively arouse the concentration of people.

devices

3 and 5. Further, as shown in the first scene of FIG. 2, the control scene information is associated with the group information, and the illumination light and the spotlight 5 of the group in which the spotlight 5 is lit (illumination group 1 in FIG. 2) are not lit. Information on the scene including the illumination light of the group (illumination group 3 in FIG. 2) may 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 associated with the group information and including the illumination light of the group in which the task light is turned on and the illumination light of the group in which the task light is not turned on. In addition, the amount of light per unit area that reaches the visual target area of the task light from the task light and base light included in the group in which the task light is lit is the amount of light from the base light included in the group in which the task light is not lit. It may be controlled so as to be less than or equal to the amount of light per unit area reaching the visual target area.

According to this configuration, the area where the task light is lit can be dimr than the surrounding area. Therefore, the degree of division of the area around which the task light is lit 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 scene information associated with the group information and including the illumination light of the group in which the task light is turned on and the illumination light of the group in which the task light is not turned on. In addition, the amount of light per unit area that reaches the visual target area of the task light from the base light included in the group in which the task light is lit, and the visual target area of the task light from the base light included in the group in which the task light is not lit. The amount of light per unit area reaching the area may be controlled to be larger than the amount of light per unit area reaching the area other than the visual target area.

According to this configuration, the work area in the centralized space and the co-creation space can be brighter than the area other than the visual target area, and efficient work can be promoted in both the centralized space and the co-creation space.

Furthermore, as described above, even if each scene is not intentionally switched instantly, it may have a remarkable effect. Specifically, the scene may be gradually switched over a predetermined time or longer, and for example, the scene may be gradually switched over 30 minutes.

According to this configuration, the scenes are gradually switched over a predetermined time or longer, so that, for example, it is possible to shift to the concentrated zone without letting the worker recognize the change. Therefore, it becomes easier for workers to naturally shift to intensive work. For example, by performing this control about 2 hours before the end of work, it becomes easier to reduce overtime hours of workers, and as a result, it is difficult to accumulate mental and physical stress. It will be easier to realize an ABW office. Or, because the peripheral vision is darkened unknowingly, it is psychologically as if a farmer in the era before the invention of the clock finished the work at the timing of nightfall and returned home instinctively. An effect that makes it easier for people to be aware of it can be expected, and as a result, overtime hours of workers are reduced, and it becomes easier to realize an ABW office that is less likely to accumulate mental and physical stress.

In the case of this modified example, the switching time of each scene is not particularly limited as long as the effect can be exhibited. For example, the switching time of each scene may be any time included in 10 minutes or more and 70 minutes or less, and for example, the above-mentioned 30 minutes or 60 minutes can be preferably adopted. In addition, the scene transition during scene switching is a mixed condition of the ratio according to the elapsed time of the dimming toning condition of the scene before the change and the dimming toning condition of the scene after the change, that is, a so-called crossfade-like scene. It may be a transition. Alternatively, one or more other scenes for the middle of switching may be played back during the scene switching, or the scenes may be gradually switched by the animation method. As described above, it is impossible to gradually change the layout so as not to be recognized by the worker by the conventional layout change by furniture and furniture, which is a remarkable effect of the present invention.

In the first embodiment, the case where the storage unit 61c stores the group information of the plurality of

devices

3 and 5 set in advance and the control scene information has been described. However, the storage unit need only store preset position information of one or more task lights and a plurality of base lights, and device identification information, and group information of one or more task lights and a plurality of base lights. , And one or both of the control scene information may not be stored. The control device of the environmental control system of the present disclosure includes at least one of the position information of one or more task lights and a plurality of base lights, the device identification information, and the position information of the lit task light and the device identification information. When at least one task light is turned on, the amount of light of the base light installed in the vicinity thereof is equal to or less than the amount of light of the base light in the area where the task light is not turned on, based on the information of. It suffices if one task light and a plurality of base lights can be controlled.

[Example 2]
In the first embodiment, the case where the zoning is executed by using the illumination light has been described, but the zoning may be executed by using not only the illumination light but also the output of sound. In the second embodiment, zoning using not only the illumination light but also the acoustic effect will be described.

FIG. 7 is a layout 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 is different 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 has a sound signal transmission unit 161c in addition to the dimming and toning signal transmission unit 161b, and outputs the sound signal transmission unit 161c to a plurality of speakers 109. Outputs a signal containing sound information. The sound control unit of the environmental control system 110 may be built in any information device, and may be built in, for example, a personal computer, a tablet, a smartphone, a single board computer, or the like.

More specifically, the sound effects of the plurality of speakers 109 will be described. As shown in FIG. 7, in the environmental control system 110, four first to fourth speakers 109a to 109d are attached to the duct rail 104, and the respective speakers 109a to 109a are attached. The 109d was wirelessly connected in stereo. Further, the first speaker 109a and the second speaker 109b form the speaker group 1, and the third speaker 109c and the fourth speaker 109d form the speaker group 2. Then, the first and

second speakers

109a and 109b belonging to the speaker group 1 output the same first audio content, and the third and

fourth speakers

109c and 109d belonging to the speaker group 2 output the same second audio content. Was output. The first and

second speakers

109a and 109b belonging to the speaker group 1 output sound to a person existing in the area of the desk group 1, and the third and

fourth speakers

109c and 109d belonging to the speaker group 2 are desks. Outputs sound to people in the area of group 2. The number of speakers belonging to the speaker group 1 may be any number, and the number of speakers belonging to the speaker group 2 may be any number. Further, as the speaker 109, a directional speaker, for example, a parametric speaker or the like may be adopted. Since ultrasonic waves are used in parametric speakers, it is possible to give remarkable directivity to the sound output direction.

With this configuration, for example, sound content recorded from the babbling sound of a stream was played back from a speaker group 1 at the top of desk group 1 via a smartphone. At the same time, the sound content recorded with jazz and bossa nova music was played back from the speaker group 2 at the top of the desk group 2 via a smartphone different from the above. Here, when I was seated at a desk belonging to Desk Group 1, I could hear the babbling sound of a stream, and I could only hear a little 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 a slight babbling sound of a stream. From the above, it was confirmed that, for example, with such a configuration, different contents can be selectively provided to some extent in different desk group units.

Furthermore, in Example 2, in addition to the sound output from the

speaker groups

1 and 2, the scene described in Example 1 was also reproduced. The sound information output by each lighting device in each scene is stored in the storage unit 161d in advance. For example, when the above-mentioned scene 1 is reproduced as lighting control in addition to the sound output from the

speaker groups

1 and 2, the desk group 1 has an effect that it is easy to increase the efficiency of the concentrated work by the lighting described in the first embodiment. And, the effect that it is easy to improve the efficiency of concentrated work by the murmuring sound of the stream 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 the concentrated work can be easily increased.

Ogawa's murmuring sound is close to the characteristics of so-called white noise and brown noise, which have strength in the entire frequency range. This characteristic is a graph of the Fourier transform spectrum that does not have intensity in the entire frequency domain when expressed graphically as the Fourier transform spectrum of frequency vs. intensity, for example, the Fourier transform spectrum of frequency vs. intensity of a specific pitch sound of a piano. In comparison with the graph of, it can be mentioned that the frequency response of the sound in the graph is broad. Sounds with this characteristic are noises that can reduce the efficiency of concentrated work that has various frequencies and is outpatient from a place other than desk group 1, as compared to sounds that tend to have no intensity in the frequency domain, for example. It has a remarkable effect of easily canceling noise, speaking voice, and the like. Therefore, workers working in desk group 1 are less likely to hear external noise. Therefore, the zone of the desk group 1 can be made into an area where the worker can easily concentrate on the work and can easily concentrate on the work.

As sound content that can improve the efficiency of concentrated work, content close to the characteristics called white noise and brown noise described above is preferable, but this is not particularly the case. For example, it may be mainly composed of natural environment sounds such as the chirping sound of a small bird, the rubbing sound of forest leaves, and the sound of waves in the sea, or it is music composed mainly of electronic sounds whose waveforms are synthesized by a music synthesizer or the like. Is also good. The sound content may be a recorded natural sound as it is, may be composed by a human being, or may be composed by a computer algorithm, AI, or artificial intelligence. The sound content may be a mixture of the above various sounds.

On the other hand, in the existing area of the desk group 2, the scene 1 is reproduced in addition to the output of the sound content recorded with the music of jazz or bossa nova. Therefore, as described in the first embodiment, the color temperature is high. The effect of relaxing and facilitating smooth communication by multiple people based on low illumination light and the effect of facilitating relaxing and smooth communication by multiple people due to jazz and bossa nova music will be superimposed. .. Therefore, due to the synergistic effect of the superposition, the zone of the desk group 2 can be made into an area where the worker can relax at each stage and smooth communication between a plurality of people can be easily planned at each stage.

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

Furthermore, jazz and bossa nova are sound contents that are favorably 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, the worker can feel a sense of relaxation and comfort, and smooth communication can be realized.

It is preferable to use sound content that is close to the characteristics called jazz or bossa nova as sound content that can promote a feeling of relaxation and smooth communication by multiple people, but this is not particularly the case. For example, classical music, healing music, natural environment sounds, and the like may be adopted as sound contents that can promote a feeling of relaxation and smooth communication by a plurality of people. Such sound content may be a recorded natural sound as it is, may be composed by a human being, or may be composed by a computer algorithm, AI, or artificial intelligence. The sound content may be a mixture of the above various sounds.

As is clear from the above explanation, it is preferable that the lighting control and the sound control are linked, and it is more preferable that the purpose of the lighting and the sound content that can be provided dominantly to each desk group is the same. By doing so, it is possible to create a synergistic effect by superimposing the effects of the purpose intended by each desk group, and to make the effect of the purpose intended by each desk group remarkable.

When lighting control and sound control are linked, the operations do not have 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 Even if there is a slight deviation, the above-mentioned effects are not lost. Further, in the case where such a deviation occurs, the deviation time between the start time or the end time of the lighting scene switching and the start time or the end time of the sound content switching may be any time, but within 30 minutes. It is preferably within 10 minutes, more preferably within 1 minute, and most preferably within 10 seconds. When the deviation time is within 30 minutes, the layout change can be achieved sufficiently quickly and with less labor than the layout change involving the transportation and re-installation of general furniture and furniture.

<Evaluation result of illuminance and volume of space in scene 1>
Next, one test result of the illuminance and volume of the space in the scene 1 will be described. FIG. 9 shows information on the irradiation light emitted by the

lighting devices

103 and 105 when the sound is output and the scene 1 is reproduced in the second embodiment, and the sound output by the speakers 109a to 109d. It is a schematic diagram explaining with the information of. Further, FIG. 10 shows when the illumination scene 1 is reproduced, the babbling sound of the stream is reproduced from the speaker group 1, and jazz or bossanova music is reproduced from the speaker group 2 in the ABW office 120 of the second embodiment. A graph showing the results of a test example when measuring the illuminance and volume of a space with an illuminance meter (CL-200: Konica Minolta) and a noise meter (SD-2200: FUSO) arranged so as to cross desks D12 to D03. Is. 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 the volume are the lowest with respect to the passage provided between the desk group 1 and the desk group 2. Then, different illumination lights and different sound contents are reproduced on both sides of the passage. Further, in the desk group 1, it is possible to realize the illumination light in which the illuminance locally and rapidly increases on the desk surface. Furthermore, in the desk group 1, the sound content that promotes the concentration of people is reproduced at a loud volume, and in the desk group 2, the sound content that gives a feeling of relaxation and comfort to the person is output in the desk group 1. It is output at about half the volume. From this, in this test example, the peripheral area of the desk group 1 and the peripheral area of the desk group 2 can be clearly separated (divided), and excellent zoning can be realized. In addition, the peripheral area of the desk group 1 and the peripheral area of the desk group 2 are reproduced by the illumination light and the sound content, respectively, so that the peripheral area of the desk group 1 can be easily concentrated by a person. On the other hand, the area around the desk group 2 can be made into an excellent co-creation space where people can feel particularly relaxed and multiple people can communicate with each other.

<Preferable configuration adopted in the second embodiment and the action and effect derived from the configuration>
As described in the second embodiment, in the environmental control system 110, the group information and the 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 scene information associated with the group information and including the illumination light of the group in which the spotlight 105 is lit and the illumination light of the group in which the spotlight 105 is not lit. Then, a speaker 109 for transmitting sound toward the visual target area is further provided, and the control device 161 has a sound signal transmission unit 161c for transmitting sound content to the speaker 109, and a sound for storing the sound content. It may have a storage unit, a control schedule for sound content, and a sound control unit for controlling at least one of the volumes. Then, the frequency characteristic of the sound content that reaches the visual target area of the spotlight 105 from the group in which the spotlight 105 is lit is the sound content that reaches the visual target area of the spotlight 105 from the group in which the spotlight 105 is not lit. It may be different from the frequency characteristic.

According to this configuration, zoning can be remarkably executed, and the effect of the intended purpose can be remarkably made in each zone. More specifically, it is preferable because the effect of zoning, that is, the function of each zone, for example, an area where it is easy to concentrate, an area where it is easy to relax, etc. can be more significantly divided. At this time, the frequency characteristics of the sound content of each zone are obtained by fast Fourier transform of the time-series data of the voice recorded by a known microphone or sound collecting device, and the sound of each zone is compared by comparing them. It is possible to determine if the content is different or how different it is.

Further, the spectral width in the fast Fourier transform in the sound content that reaches the visual target area of the spotlight 105 from the group in which the spotlight 105 is lit reaches the visual target area of the task light from the group in which the spotlight 105 is not lit. It may be wider than the spectral width in the Fast Fourier Transform in the sound content.

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