Abstract

An environment control system (10) is provided with: one or more spotlights (5) for illuminating the upper surface of the indoor table; one or more base lamps (3) for illuminating an area in the room, the area being larger than the upper surface; one or more speakers (9) for outputting sound indoors; and a control device (61). The control device (61) performs the following zone control: a concentrated control area in which the illuminance of the spotlight (5) is greater than that of the base lamp (3) and a non-concentrated control area in which the illuminance of the spotlight (5) is less than that of the base lamp (3) are generated with a buffer area interposed therebetween. In the zone control, the average illuminance in the buffer area is lower than the average illuminance in the central control area and the average illuminance in the non-central control area, and the average sound volume in the buffer area is lower than the average sound volume in the central control area and the average sound volume in the non-central control area. In this way, flexible partitioning that easily meets the demand for each space can be achieved.

Description

Environmental control system

Technical Field

The present disclosure relates to an environmental control system.

Background

Beginning with the innovation of the Working mode, ABW (Activity Based Working) offices are emerging. An ABW office is for example an office of the form: the performance of workers and organizations is made efficient by selecting a space with a design theme different from that of the kinds and amounts of work that varies from time to time, such as when workers want to work together by one person, when workers want a plurality of persons to work in groups, when workers want to have a rest/relax, and the like, or the intention of the workers themselves based on emotions and motivations. As a method for creating a space having a different design theme, for example, a method is known as described in patent document 1: a space is created and partitioned by using daily utensils and furniture, and the efficiency of centralized work is improved.

Disclosure of Invention

Problems to be solved by the invention

It is desirable to continuously change the partition of the ABW office according to the work performance of the flow of workers and organizations and the demand for each space. For example, even after the above-described compartment (booth) type daily equipment/furniture is installed, the arrangement and the number of the appliances/furniture can be changed in different areas in accordance with the excess or deficiency of the utilization rate. However, work performance of workers and organizations and demands for each space may be generated in a period of every hour, every day, every month, and the like, and it is difficult for the workers and the labor to continuously perform operations such as transportation, rearrangement, storage into a warehouse, and the like of daily appliances and furniture in the above-described period, and there is a problem in flexibility of design change as a method for realizing the ABW office.

Therefore, an object of the present disclosure is to provide an environment control system capable of performing flexible zoning that can easily cope with the demand for each space and the work performance for the flow of people (staff, etc.) and organizations that is generated at a period of every hour, every day, every month, etc.

Means for solving the problems

In order to solve the above problem, an environment control system according to the present disclosure includes: more than one working lamp for illuminating the upper surface of the table in the room provided with a plurality of tables; one or more base lamps for illuminating an area in a room, the area being larger than the upper surface; one or more speakers that output sound indoors; and one or more control devices, wherein the control device performs the following partition control: the dimming and toning control is performed on one or more working lamps and one or more base lamps so that a centralized control area and a non-centralized control area are generated with a buffer area interposed therebetween, the centralized control area is an area where the illuminance of the working lamps is greater than that of the base lamps, and the non-centralized control area is an area where the illuminance of the working lamps is less than that of the base lamps.

Here, the centralized control area is defined as follows. More specifically, when two or more desks having upper surfaces at which the illuminance of the worklight is greater than that of the base light are disposed in a continuous and adjacent manner, a line segment area (an area viewed as a line segment in the vertical direction) from one end to the other end of one or more upper surfaces of one or more desks at which the plane intersects, when an arbitrary plane intersecting at least one of the two or more desks, out of planes including the vertical direction, is considered, is defined as the centralized control area.

In addition, when the tables having the upper surfaces on which the illuminance of the worklights is greater than that of the base lamp are not arranged continuously and adjacently but the tables having the upper surfaces on which the illuminance of the worklights is greater than that of the base lamp are in an isolated state, when an arbitrary plane intersecting the one table is considered, a line segment region (a region which is viewed as a line segment in the vertical direction) from one end to the other end of the upper surface of the table intersecting the plane is defined as the centralized control region.

The non-centralized control area is defined as follows. More specifically, when two or more desks having upper surfaces at which the illuminance of the worklight is lower than that of the base light are disposed in a continuous and adjacent manner, a line segment area (an area viewed as a line segment in the vertical direction) from one end to the other end of one or more upper surfaces of one or more desks at which the plane intersects is defined as the non-centralized control area when an arbitrary plane intersecting at least one desk of the two or more desks, out of planes including the vertical direction, is considered.

In the case where the tables having the upper surfaces with the illuminance of the worklights lower than that of the base light are not arranged continuously and adjacently, but the tables having the upper surfaces with the illuminance of the worklights lower than that of the base light are in an isolated state, when an arbitrary plane intersecting the one table is considered, a line segment region (a region viewed as a line segment in the vertical direction) from one end to the other end of the upper surface of the table intersecting the plane is defined as the non-centralized control region.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the environment control system of the present disclosure, it is possible to easily cope with the work performance of the flow of people and organizations generated in a cycle of every hour, every day, every month, or the like, and the demand for each space.

Fig. 1 is a diagram showing an example of a layout of the arrangement of the plurality of desks D01 to D14 in the ABW office 20 as an example of a room in which the environment control system 10 according to an embodiment of the present disclosure is installed, and is a layout diagram in which the arrangement of the plurality of desks D01 to D14 when viewed from above and the arrangement of the base lamp 3, the power-on lamp rail 4, the spotlight 5, and the speaker 9 mounted on the ceiling of the ABW office 20 are described as being superimposed on the arrangement of the desks D01 to D14.

The environment control system 10 in the present disclosure uses the base lamp 3, the spotlight 5, and the speaker 9, and divides two areas by setting a part of the area of the ABW office 20 as an excellent centralized control area where a person is particularly apt to concentrate on a job from both lighting and sound, and setting the other part of the area of the ABW office 20 as a non-centralized control area (a shared area) where a person is particularly apt to feel a sense of relaxation and which is also excellent in that a plurality of persons communicate with each other. Next, a method for realizing the division of the two regions will be described in detail from the viewpoint of the illumination light and the viewpoint of the sound.

[1. zoning Using illumination light ]

As shown in fig. 1, in one embodiment of the ABW office 20, a total of 14 office tables D01 to D14, which are general office tables, are classified into a desk group 1 and a desk group 2, 28 LED dimming and color-adjusting base lamps (for example, NNLK41515+ NNL4600EXDK 9: panasonic) as ambient lighting for illuminating the ABW office 20 are provided at regular intervals above the desk groups, and 3 rows of lamp rails 4 for power supply are provided in the vicinity thereof. Specifically, 14 desks D01 to D14 in total are arranged in 4 rows, and 3 power supply lamp rails 4 are arranged in the vicinity of 3 desks D01 to D14 in the 4-row desks D01 to D14 so as to extend in a direction substantially parallel to the extending direction of the rows.

A total of 14 LED dimming spotlights (for example, NTS 05121W: loose) 5 as an example of the work lights are provided on each of the lamp rails 4. A wavelength conversion filter is added to the opening of each spot light 5, and the color temperature of the output light from the spot light 5 is adjusted to 6000K. The total of 14 desk lamps D01 to D14 are in one-to-one correspondence with the total of 14 spotlights 5, and the installation positions and the installation directions of the spotlights 5 are adjusted so that the spotlights 5 illuminate the center portions of the corresponding desk lamps D01 to D14.

The 28 base lamps 3 and 14 spotlight 5 are connected in sequence via dimming signal lines to a multi-manager (japanese: マルチマネージャー, for example, NQ 51101: panasonic), an LS/PD signal conversion interface (NK 51111: panasonic), a PD/dimming signal conversion interface (NK 51012: panasonic) and a pip + individual unit controller a type (japanese: セパレートセルコン a タイプ, for example, NQ 23171Z: panasonic) as examples of the control device. In addition, 7 spotlights 5 were paired for each of the prepared 2 pints + individual unit controller a types.

Next, using the multi-manager operation application, the position information of each basic lamp 3 is stored by the mapping work of 28 basic lamps 3, and as shown in fig. 1, 12 basic lamps 3 and 8 spot lamps 5 are set as the lighting apparatuses belonging to the lighting group 1, 4 basic lamps 3 are set as the lighting apparatuses belonging to the lighting group 2, and 12 basic lamps 3 and 6 spot lamps 5 are set as the lighting apparatuses belonging to the lighting group 3. As shown in fig. 2, 4 scenes are set for each of the lighting groups 1 to 3, and values of the color temperature and the dimming ratio of each group in each scene are set.

Here, setting of each scene can be easily performed using an information terminal, for example, a smartphone, a tablet computer, a remote controller, or the like, in which an application for setting an existing scene is installed. Then, the scenes are actually reproduced. Specifically, when scene 1 is reproduced using operation unit 64 (see fig. 3) after the blinds of the windows of ABW office 20 are completely closed, desk group 1 and desk group 2 are divided into separate parts in appearance. Next, when other scenes such as scene 3 and scene 4 are sequentially reproduced using the operation unit 64 (see fig. 3), each scene is switched in the order of several seconds.

The writing desk group 1 in scene 1 is an uneven illuminance distribution in which only the central portions of the desks D07 to D014 have high illuminance and the illuminance decreases as the distance from the central portions increases. Further, the illumination intensity of the floor, wall, and the like around the desk is also low and the brightness is low. On the other hand, in the desk group 2 of the scene 1, the illuminance distribution of the desks D01 to D06 is high in uniformity as compared with the desk group 1, and the illuminance of the floor, wall, and the like around the desk is also high and the brightness is high.

At this time, when the worker sits on the desk group 1, the central portions of the desks D07 to D014, which the worker should watch more, are illuminated with high illuminance, and therefore, the noise factor for recognition of the peripheral visual field is reduced, so that the worker is likely to be buried in the work, and the efficiency of the concentrated work is likely to be improved. In addition, in this technique, the visibility of the peripheral vision of the wall, floor, and the like is reduced by setting the dimming ratio of the base lamp 3 low, and therefore, the effects of being countersunk in the desks D07 to D014 and the work can be more easily improved. Further, by setting the dimming ratio of the base lamp 3 low, the worker who is working with the desk group 1 cannot see the expression of the face when other workers see from the outside or cannot see pleasure due to the shadow of the face, and therefore, it is difficult to make a call. That is, the probability of the worker who is performing work using the desk group 1 being called by another worker and causing a job interruption is likely to decrease, and as a result, the efficiency of the collective work is likely to be improved for the worker who is performing work using the desk group 1. As described above, when scene 1 is reproduced, the desk group 1 is a space that is easy to function as a centralized space, and can be handled as a space that corresponds to the centralized control area in the present disclosure. On the other hand, in scene 1, since the desk group 2 has a low color temperature and is easy to improve relaxation feeling and the amount of communication performed by a plurality of people, it is a space that is easy to function as a shared space and can be handled as a space that corresponds to the non-centralized control region in the present disclosure.

The spatial illuminance distributions of the desk group 1 and the desk group 2 are greatly different. In particular, the desk group 1 is characterized by a lower illuminance on the floor, wall, or the like around the desk, which is a factor of the high feeling of separation of the two desk groups in terms of the appearance space. Further, since the color temperatures of the illuminations of the desk group 1 and the desk group 2 are greatly different, the sense of spatial division in appearance is high. According to the above, the partition effect can be obtained without using daily utensils, furniture, and the like.

The partitioning effect is, for example, a perception of a cognitive separation of spaces, and can include an effect that a plurality of spaces are actually different spaces in appearance from the viewpoint of a human being. Alternatively, the following effects may be included: the intention of the worker in the partition is easily prompted by the recognition to change the action and the action line of the worker. For example, when the space to be concentrated is divided into regions, the following effects are exhibited: the staff who sees the partition does use the space for the main purpose of performing centralized work. In addition, the following effects can be included: this shows subjective feelings of effect and trends of physiological/psychological/biological actions and subjects in the case where the worker actually uses these spaces for purpose. For example, when a worker uses the location in a partition of the space intended to be concentrated, the worker can obtain a sense of being concentrated with certainty or can obtain an index or data indicating that the worker is concentrating as a biopsychological effect. The office space with a high zoning effect is suitable for an ABW office in which a worker selects a space with a different design theme corresponding to the worker's own intention based on emotion and motivation.

Regarding the partition effect, the larger the difference in the illuminance distribution and the color temperature or the difference in the volume and the content of the sound of each group is, the more easily the effect is improved. According to this method, since the space can be partitioned without using daily equipment and furniture, the design feeling of the space can be easily improved, and when the lighting control such as dimming and toning is digitalized, flexible partitioning in which the layout is instantaneously changed can be performed by the lighting control, which is preferable. Also, a buffer region exists between the desk group 1 and the desk group 2. This area is not intended to be a space created by a worker for some purpose, but is used as a space for an aisle or the like in a general office. In the buffer area, the illumination and sound are made different from those of the desk group 1 and the desk group 2, and thus the effect of partitioning is improved compared to the case where the desk group 1 and the desk group 2 are adjacent to each other. The maximum width of the buffer area is not particularly limited, but is preferably in the range of 0.5m to 5m because the partitioning effect is easily improved while maintaining the functional density of the office space.

Further, since the contents of the work that the operator is prompted to perform are different between the desk group 1 and the desk group 2, for example, the concentrated work is prompted to be performed in the desk group 1 and the relaxation and communication are prompted to be performed in the desk group 2 of the present embodiment, the effects are different not only in the appearance but also in the method of using the functionality of each space, and thus the effects also contribute to the partitioning effect.

In addition, in the case of performing the partition by this method, switching of each scene is completed within several seconds, and as a result, the layout of the office can be changed within several seconds. For example, on a day when the demand for the collective space is high, such as a day when the office is busy, if the scene 1 is switched to the scene 3, the number of seats in the collective space in the office is increased from 8 to 14, and the demand for the collective space by the worker is satisfied, so that the work performance of the worker or the organization is easily improved. Alternatively, in the case of a leisure day, if the scene 4 is switched, the number of seats in the collective space is 0, and the number of seats in the shared space is 14, so that the pressure of the tissue is easily reduced, and the traffic volume is easily increased. Further, the seating number of the concentration space in the afternoon can be adjusted during the noon break with reference to the utilization rate of the concentration space in the morning on a certain day. According to this method, as described above, if a method using daily appliances/furniture is used, flexible division in which the layout is changed at intervals of an hour, a day, a month, or the like, which is difficult to realize, can be performed. In a conventional office scene, areas such as desks and aisles are generally illuminated with high uniformity of color temperature and illuminance distribution. In contrast, the present application uses such an illumination technique and control method, and therefore, particularly in an ABW office scene, a significant effect that cannot be expected from conventional knowledge of illumination can be achieved.

[2. zoning Using Sound ]

Referring again to fig. 1, in the environment control system 10, 4 speakers, i.e., first to fourth speakers 9a to 9d, are attached to the light rail 4, and the speakers 9a to 9d are wirelessly connected in stereo. In the present embodiment, the speakers 9a to 9d are made of LSPX-103E26 (sony), but any speaker other than these may be used. The first speaker 9a and the second speaker 9b constitute a speaker group 1, and the third speaker 9c and the fourth speaker 9d constitute a speaker group 2. The first speaker 9a and the second speaker 9b belonging to the speaker group 1 output the same first sound content, and the third speaker 9c and the fourth speaker 9d belonging to the speaker group 2 output the same second sound content. The first speaker 9a and the second speaker 9b belonging to the speaker group 1 output sounds to a person existing in the area of the desk group 1, and the third speaker 9c and the fourth speaker 9d belonging to the speaker group 2 output sounds to a person existing in the area of the desk 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 9, a directional speaker, for example, a parametric speaker or the like may be used. In the parametric speaker, since ultrasonic waves are used, the output direction of sound can be made to have a significant directivity.

In the above configuration, for example, by transmitting a control signal by wireless to the speaker group 1 located at the upper part of the desk group 1 via the smartphone, the sound content obtained by recording the sound of the rippling stream of the brook is reproduced from the speaker group 1. Meanwhile, sound contents obtained by recording jazz music or bosanova music are reproduced from the speaker group 2 located at the upper part of the desk group 2 via a smartphone different from the above. When sitting on a desk belonging to the desk group 1, the gurgle of the brook is heard, while the jazz music and bosanova music are heard only a little. On the other hand, when sitting on a desk belonging to the desk group 2, jazz/bosanova music was heard, while the rippling of the creek heard only a little. As described above, for example, it is possible to confirm that: with such a configuration, different contents can be selectively provided to some extent in units of different desk groups.

The reproduction by the speaker groups 1 and 2 may be performed by using an information terminal (for example, a tablet pc, a personal computer, or the like) other than a smartphone, or may be performed by using an operation unit provided on a wall surface of the ABW office 20. The reproduction by the respective speaker groups 1 and 2 may be performed not by a control signal based on a wireless signal but by a control signal based on a wired line.

The reproduction of sound by the speaker groups 1 and 2 is performed by setting a reproduction scene based on a scene in advance. Specifically, as shown in fig. 2, information on the sound output from each lighting device in each scene is stored in the storage unit 61d (see fig. 3). For example, when reproducing the scene 1, the illumination light is emitted, the rippling water sound of a brook is output from the speaker group 1, and the sound content obtained by recording the music of jazz or bosanova is output from the speaker group 2.

The rippling water noise of the creek has characteristics close to those of a sound having intensity in the entire frequency region, which is called white noise or brownian noise. When the characteristic is expressed as a frequency-intensity fourier transform spectrum by a curve, the frequency characteristic of the sound in the curve of the characteristic is wider than that of a curve of a frequency-intensity fourier transform spectrum having no intensity over the entire frequency range, for example, a curve of a frequency-intensity fourier transform spectrum of a specific musical scale of a piano. The sound having this characteristic has the following remarkable action effects: it is easy to eliminate noises, such as rattles, speech sounds, etc., having various frequencies and coming from places other than the desk group 1, which may reduce the efficiency of the concentrated work, as compared with sounds having a tendency not to have intensity in the frequency region. Thus, the worker who works using the desk group 1 does not easily hear the extraneous noise. This makes it possible to set the region of the desk group 1 to a region where it is easier for the worker to concentrate on the work and to bury the work. That is, the following effects are provided in the present disclosure: further improving the effect of centralizing the control area.

As the content of the sound capable of improving the efficiency of the collective operation, a content close to the above-described characteristics called white noise and brownian noise is preferable, but the content is not particularly limited thereto. For example, the content may be mainly natural environmental sounds such as bird singing, leaf rubbing sounds of forests, and sea waves, or the music may be mainly electronic sounds obtained by waveform synthesis using a synthesizer for music or the like. The audio content may be a content obtained by recording natural sound as it is, a content obtained by composing music by a person, or a content obtained by composing music by a computer algorithm, AI, or artificial intelligence. The audio content may be a mixture of the above plural kinds of audio.

On the other hand, since the scene 1 is reproduced in addition to the output of the audio contents obtained by reproducing the music of jazz and bosanova in the existing region of the desk group 2, as described in embodiment 1, the effect of easily promoting relaxation by illumination with the illumination light having a low color temperature and the effect of easily promoting relaxation by a plurality of people and the effect of easily promoting smooth communication by jazz and bosanova are superimposed. Thus, the region of the desk group 2 can be set as a region in which the worker can be greatly relaxed and smooth communication of a plurality of people is remarkably easily achieved by the complementary effect obtained by the superimposition. That is, the following effects are provided in the present disclosure: further improving the effect of the non-centralized control area.

Jazz/bosanova music has the following characteristics: the frequency characteristics of sound in a fourier transform spectrum curve of frequency versus intensity are not broad as compared with the white noise and the brown noise described above. This is caused by the fact that instruments such as pianos, saxophones, and bass which are played mainly with jazz and bosanwa are used in a state of being strictly tuned so as to output sounds of a specific single scale, that is, do, re, mi, fa, sol, la, si, do, and chromatic scales thereof. Therefore, although the function of eliminating the noise against the extraneous noise described above is likely to be insufficient, the need for the function of eliminating the noise is not great in the shared space where relaxation is originally intended and communication by a plurality of persons is performed, and therefore, even if the function of eliminating the noise is insufficient, a large adverse effect is not generated.

Also, jazz, bosanow, and the like are sound contents that are preferably provided in cafes and relaxation facilities, and are frequently used in the case of promoting relaxation and smooth communication of many people. Therefore, it is obvious from this that if these sound contents are used, the worker can feel a sense of relaxation and a sense of calm, and can realize smooth communication.

As contents of sounds that can promote relaxation and smooth communication by a plurality of people, contents having characteristics close to those of what are called jazz and bosanova are preferably used, but the contents are not particularly limited thereto. For example, as the content of the sound that can promote relaxation and smooth communication by a plurality of people, classic music, music for curing soul, natural environment sound, and the like may be used. Such audio content may be obtained by recording natural sound as it is, by composing a song by a person, or by composing a song by a computer algorithm, AI, or artificial intelligence. The audio content may be a mixture of the above plural kinds of audio.

[3. complementary effects of partitioning using illumination light and partitioning using sound ]

In the present embodiment, the gist of illumination and audio contents that can be dominantly provided to the writing desk groups 1 and 2 in conjunction with the audio control is the same. More specifically, for example, when the scene 1 is reproduced, the above-described illumination light which is likely to cause a person to exert concentration is irradiated to the area of the desk group 1, and the speaker group 1 outputs the rippling water sound of the creek which is likely to improve the efficiency of the concentration work. Thus, in the region of the desk group 1, the effect of easily improving the efficiency of the concentrated work by the illumination and the effect of easily improving the efficiency of the concentrated work by the sound can be superimposed, and the region of the desk group 1 can be changed to the region of easily remarkably improving the efficiency of the concentrated work by the complementary effect of the superimposition.

On the other hand, the above-described illumination light which is easy to enhance the sense of relaxation and the amount of communication of a plurality of people is irradiated to the region of the desk group 2, and the speaker group 2 outputs jazz and bosanova which are easy to enhance the sense of relaxation and the amount of communication of a plurality of people. Therefore, in the region of the desk group 2, the effect of easy enhancement of relaxation feeling and communication by illumination and the effect of easy enhancement of relaxation feeling and communication by sound can be superimposed, and the region of the desk group 2 can be changed to a region of easy enhancement of relaxation feeling and exceptionally easy communication by the complementary effect of the superimposition. This makes it possible to make the effect intended by the region of each of the desk groups 1 and 2 remarkable.

In addition, when the lighting control is linked to the audio control, the operations thereof do not need to be strictly synchronized, and for example, even if the start time or end time of the scene switching of the lighting and the start time or end time of the switching of the audio content are slightly different, the above-described operation and effect are not lost. When such a deviation occurs, the time of the deviation between the start time or end time of the scene switching of the lighting and the start time or end time of the switching of the audio content may be any time, but is preferably within 30 minutes, more preferably within 10 minutes, even more preferably within 1 minute, and most preferably within 10 seconds. When the time of the deviation is within 30 minutes, the layout change can be performed quickly enough compared to the layout change accompanied with the transportation or resetting of general daily appliances or furniture, and the layout change can be performed with less labor.

[ general overview of the Environment control System 10 and detailed description of the respective major configurations ]

Next, the overall outline and each main configuration of the environmental control system 10 will be described in detail. Specifically, first, an overview of the entire environment control system 10 will be described, and then, the positional information, the device identification information, and the respective configurations of the environment control system 10 will be described in detail. Further, as for the sound content, detailed description has been made above, and thus, description is omitted.

< overview of the Environment control System 10 as a whole >

Fig. 3 is a block diagram showing the main structure of the environment control system 10. As shown in fig. 3, the environment control system 10 includes an operation unit 64 in addition to the base lamp 3, the spotlight 5, and the control device 61 including a multi-manager, and the control device 61 includes a control unit 61a, a light/color adjustment signal transmitting unit 61b, an audio signal transmitting unit 61c, and a storage unit 61 d. The control device 61 is preferably constituted by a computer, for example, a microcomputer, and the control section 61a, that is, the processor, includes, for example, a CPU (Central Processing Unit). The storage unit 61c is configured by a nonvolatile Memory such as a ROM (Read Only Memory) or a volatile Memory such as a RAM (Random Access Memory). The CPU reads out and executes a program or the like stored in advance in the storage section 61 d. The nonvolatile memory stores a control program, a predetermined threshold value, and the like in advance. The volatile memory temporarily stores the read program and processing data. The storage unit 61d stores position information and device identification information about each of the one or more spotlight 5 and the plurality of base lamps 3, which are set in advance. The storage unit 61d stores data for reproducing the light-adjustment and color-adjustment of the scenes 1 to 4. In addition, the storage unit 61d stores the contents output from the speaker groups 1 and 2 and the volume of the contents output from the speakers 9 in each of the above-described scenes 1 to 4. The audio signal transmitting unit 61c of the control device 61 outputs signals including audio information to the plurality of speakers 9.

Further, the sound control unit of the environment control system 10 may be built in any information device, for example, a personal computer, a tablet computer, a smart phone, a single board computer, or the like. In addition, in the embodiment shown in fig. 1, 8 desks D07-D014 belong to desk group 1 and 6 desks D01-D06 belong to desk group 2, but the number of desks belonging to desk group 1 and desk group 2 is not limited to the embodiment. The number of the lighting groups is not limited to 3 as in the embodiment, and two or more lighting groups may be present.

(information)

< location information >

The positional information may be information similar to the absolute value of coordinates such as the actual position in space, or may be information of a relative positional relationship with reference to a certain spotlight, a basic light, a pillar or the like already provided in space. The position information stored in the storage unit 61c may be information that can be reproduced (defined) only partially, without being able to completely reproduce the positions and positional relationships of the spot light and the base light that are actually installed. The position information may be recorded in the storage unit by user input, or may be recorded by an algorithm of an AI or a computer. The position information may be set and recorded by referring to or in association with drawing data stored in a separate storage unit or the like. Further, it is not necessary to give location information to all the devices included in the environment control system or to associate location information with all the devices, and it is also possible to make an appropriate selection according to the situation of the user.

< device identification information >

The device identification information is information that can be identified by the device, such as a spotlight or a base light, and is constituted by a manufacturing number, a MAC address, an IP address, a product number, and the like. The device identification information is used when setting/recording the above-described position information, group, scene, or when setting/recording the output parameters (the color tone ratio, the light tone ratio, and the like) of the devices individually so that different devices in the environment control system are not determined to be the same device unintentionally. The device to be given or associated can be appropriately selected according to the situation of the user without giving the device identification information to all the devices included in the environment control system or associating the device identification information with all the devices.

(details of the respective structures)

< working Lamp >

The equipment form of the work light is not particularly limited, and a desk lamp, a downlight, or the like can be used as the work light in addition to the spotlight 5 described above, but it is preferable that the work light is a light whose light distribution is controlled such that light is concentrated in a specific region like a spotlight because the illumination range of the desk is easily controlled. More specifically, the spotlight 5 may have a structure in which the irradiation direction of the spotlight 5 is adjusted by a person applying an external force, or may have a structure in which the irradiation direction of the spotlight 5 can be automatically adjusted to any one of the lower directions by freely rotating two rotation shafts by a motor or the like using a remote controller. When the at least one spotlight 5 can change the emission direction of the illumination light to any direction at the installation position, then the degree of freedom of the gap between the desks in the long-side direction in the concentration space can be increased, and also the degree of freedom of the gap between the desks in the width direction in the concentration space can be increased, so that the degree of freedom of the layout of the concentration space can be increased. In addition, when the irradiation direction of the spotlight 5 can be freely adjusted by the remote controller, the irradiation direction of the spotlight 5 can be safely adjusted from the ground without using a ladder or the like, at least one spotlight 5. Further, as described above, it is preferable to use a spotlight of a dimming and color-adjusting type as the work light.

The task lamp is an illumination for improving the efficiency of work by an operator, for example, work such as personal computer work, note-taking work, and reading work, and is an illumination for selectively illuminating a visual target area of a desk. The visual target area is an area that is generally likely to enter the visual field when a work is performed using the desk, and for example, when a personal computer (hereinafter, simply referred to as a personal computer) is placed on the back side of the center of the desk and operated, the center of the desk is the center of the visual target area. In this case, the change of the visual object due to the change of the posture or the visual line caused by physiological factors or sporadic occurrence is not considered. That is, the following phenomenon is not considered as a significant change in the visual object regions in the desks D01 to D14: looking up at the ceiling for temporary thinking, stretching to lazy waist; moving the sight to the wall; sneezing and coughing can cause the user to see the floor; the line of sight is moved by being called by someone.

The illumination range of the work light is preferably defined as a part of the visual object area, and for example, it is preferable that 30% to 90% of the area of the desk is the illumination range. The illumination range of the work lamp is not particularly limited, and is preferably substantially circular or substantially polygonal. As a result, the luminance of the visual target region becomes brighter than the luminance of a region other than the visual target region, and the cognitive noise in the peripheral visual field is reduced. Therefore, the awareness of the worker is directed to the desk side, and the work efficiency is easily improved.

Here, the illumination range can be calculated as a range generally called a half-value width, where the maximum value of the amount of light per unit area reaching the desk is halved. The illumination range can be measured and calculated by using a known illuminometer. The color temperature of the operating lamp is not particularly limited, but is preferably 4000K to 6500K because cognitive concentration is likely to be improved.

< basic Lamp >

The base lamp is an illumination for increasing the brightness of the room, and is an illumination for uniformly illuminating the room. In order to uniformly illuminate the room, the light distribution of the base lamp is preferably in a range larger than that of the spotlight. The color temperature of the base lamp is not particularly limited. The base lamp is preferably dimmable and dimmable. The device form of the base lamp is not particularly limited, and any device form such as a ceiling lamp, a line lamp, a head lamp, a spotlight, and a light bar can be used.

< speaker >

Although any speaker may be used, a directional speaker, such as a parametric speaker, or the like, is preferably employed as the speaker 9. Since ultrasonic waves are used in the parametric speaker, the output direction of sound can be made to have a significant directivity. The number of the writing desks to which the sound outputted from the respective speakers mainly arrives may be any number, may be only one, or may be two or more.

< control device >

The control device 61 is a device for controlling the work 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, and as the device form of the control device 61, for example, the above-described illumination control device and the control application of the illumination control device can be preferably used. The device control application may be installed in a tablet pc illustrated in fig. 3, or in other terminals such as a personal computer and a smartphone, and in this case, it is preferable for the user to easily set, manage, and operate the lighting control device.

In the example shown in fig. 3, the control device 61 is built in the tablet pc 60, but the control device does not necessarily need to be built in an operation terminal such as a tablet pc, and as shown in fig. 4, the control device 71 of the environment control system 70 may be a terminal or a device different from the operation terminal such as the tablet pc 72. Here, the control device 71 may be configured such that a housing thereof is embedded in a ceiling or a wall surface, or may be fixed to a floor or a storage rack. The control device 71 may be controlled by signal communication with an information terminal such as the tablet pc 72 by a wired system, or by signal communication by a wireless system such as Wi-Fi or Bluetooth (registered trademark). In this case, although not particularly shown in fig. 4, the control device 71 may include a communication device having a port for connecting a signal line for communication and an access point of a wireless LAN. In this case, the tablet pc 72 and the like may not directly communicate with the spotlight 5 and the base lamp 3. At this time, information on the positions and control conditions of the appliances constituting the environment control system 70, such as a map, a scene, a group, and a control schedule set by the operation unit 75 of the tablet pc 72, may be transmitted to the control device 71 and recorded in the storage unit 76 of the control device 71. In this case, even when the power supply of the tablet pc 72 is turned off or the tablet pc 72 is stored in a place outside the communication range with the spotlight 5 or the base lamp 3, the intended environmental control can be performed. The control device 71 may not have a user interface for operation such as a liquid crystal display. In this case, the control device 71 is preferably easy to be downsized, and is improved in installation easiness and design feeling. Although not particularly shown in fig. 4, the operation terminal such as the tablet pc 72 may have a storage unit. Although not particularly shown, the control device 71 may be a terminal different from the terminal for each series of lighting control and speaker control. For example, the following method is also possible: the control device of the series of lighting controls is a multi-manager and the control device of the series of speaker controls is a smartphone. Further, although the environment control system 70 shown in fig. 4 is a modification of the environment control system 10 shown in fig. 3, it is clear that there are many environment control systems of modifications that can be realized and are conceivable in addition to the environment control system 70 shown in fig. 4.

< light/color modulation Signal transmitting section >

The dimming/toning signal transmitting section 61b is a section that transmits a dimming/toning signal to the work light and the base light to cause the work light and the base light to perform at least one of dimming and toning, and the dimming/toning signal transmitting section 61b is included in the control device 61. The signal format is not particularly limited, and any signal format such as a known dimming signal, Wi-Fi, BlueTooth (registered trademark), or the like can be used. In addition, in the above-described dimming/toning control, the dimming/toning control by the digital control method is described, and the control method of transmitting the digital signal (PDCL) from the lamp controller is described. In this control method, not only the power supply line but also the wiring of the signal line for digital control is required. In this digital control, since communication of detailed information is possible, control using a large amount of information is possible, and control based on a wireless signal is also included in this method.

However, when dimming and toning control is performed, a phase control method may be employed, and dimming control may also be performed by directly adjusting power supplied to the illumination apparatus. In this embodiment, the power supply current to the lighting device is directly controlled, and thus the lighting device is easily affected by voltage fluctuation, but since a dedicated signal line does not need to be separately drawn, workability is excellent. In addition, when dimming and toning control is performed, a signal line system may be employed, and a dimming signal (duty signal) may be transmitted from a lamp controller, and the luminance of a light emitting portion such as an LED may be controlled by a power supply unit on the device side. In this method, the power supply line and the wiring of the dimming signal line are required, but the method is less susceptible to the influence of the line voltage, and therefore smooth dimming control without flicker can be performed. In addition, on/off control of only the operating lamp and the base lamp is also included in the dimming control.

< Audio Signal transmitting section >

The audio signal transmitting unit 61c is a part that transmits an audio control signal to the speaker 9 to change the content and appropriately change the volume of the audio output from the speaker, and the audio signal transmitting unit 61c is included in the control device 61. The signal format is not particularly limited, and any signal format such as known Wi-Fi and BlueTooth (registered trademark) can be used.

< storage section >

Any known device may be used as the device constituting the storage unit. The storage unit may not be incorporated in the control device unlike the configuration shown in fig. 3, and may be constituted by, for example, an information terminal different from the information terminal including the control device, such as a smartphone, a tablet computer, or a personal computer, or a server, a workstation, or an external storage medium on the cloud. The storage unit may be configured to be basic by a user, or may be configured to be rewritten by the device through the cloud and the AI.

< group information of a plurality of devices >

The group information of a plurality of lighting devices is managed, for example, by an application. The packetization may be performed by, for example, operating a tablet terminal to perform setting/saving. The plurality of devices that are packetized are simultaneously sent the same command, for example, are applied with the same dimming/toning control. Further, regarding dimming/toning control, i.e., group control, of a plurality of devices grouped together, signal delay is allowed, and variation in operation of the devices is also allowed. For example, the allowable variation in the operation of the device is within 30 minutes, more preferably within 10 minutes, still more preferably within 1 minute, and most preferably within 10 seconds, and the delay of the signal or the command converging within this range is included in the behavior of the plurality of devices subjected to the packetization. When the operation deviation of the equipment is within the above time, it is preferable that the layout change is performed quickly enough compared to a general layout change involving transportation or rearrangement of daily appliances or furniture, and the layout change is easily performed with less labor. The function of the application program for operating the control device may include setting of the group, but is not limited to being defined by the name "group". If the group is set in advance in the application program for operating the control device or in the storage unit included in the control device, it is easy for the user to manage and change the lighting and the control parameters thereof, which is preferable.

< control scenario information >

It is a very complicated task for a user to set various control parameters such as dimming ratio and color ratio for a plurality of lighting apparatuses and reproduce the control parameters. This is because, in a general ABW office, 10 or more or 30 or more lighting apparatuses are used, and if there are many lighting apparatuses, 100 or more lighting apparatuses are used. Therefore, a method of storing and managing control parameters of a plurality of lighting apparatuses in a storage unit is known, and this is referred to as a scene in the present application. In this way, it is easy for the user to manage the conditions of the control parameters for the plurality of lighting apparatuses, and to instantaneously reflect (hereinafter, referred to as reproduction) the conditions at a desired timing by the plurality of lighting apparatuses, which is preferable. The user can instantaneously switch the intended two or more setting conditions by storing a plurality of scenes in the storage unit in advance. The setting of each scene may be set in any manner according to the use requirement, and for example, unlike the example shown in fig. 2, the dimming rates of 10 base lamps may be set to 100% in the scene 1 and stored in the storage unit, and the dimming rates of the 10 base lamps described above may be set to 30% in the scene 2 and stored in the storage unit. Further, if scene 1 is reproduced, the state may be instantaneously changed to a state in which the dimming rates of 10 base lamps are set to 100%, and if scene 2 is reproduced from this state, the state may be instantaneously changed to a state in which the dimming rates of 10 base lamps are set to 30%. In this way, it is preferable to perform dimming control of many lighting apparatuses in a very short time and with less labor than the work of resetting the dimming ratio of 10 lighting apparatuses each time. Further, the setting of a scene may be included as a function of an application program for operating the control device, but is not limited to being defined by a name such as "scene". Further, the setting of each scene may be set as follows for the scenes of the groups 1 and 2. For example, in scenario 1, set 1: dimming ratio 0%, group 2: the dimming ratio of 50% may be set to set group 1: dimming ratio 50%, group 2: the dimming ratio is 0%. If the scene is set in this manner, it is possible to instantaneously exchange a region in which workers can easily gather and a region in which workers can easily relax and can easily communicate with other workers, and when the sizes of the two regions are different, it is possible to instantaneously change the size of each region as needed. In addition, regarding dimming/toning control, i.e., group control, of a plurality of devices that have been made into a scene, a signal delay is allowed, and variations in the operation of the devices are also allowed. For example, the allowable variation in the operation of the device is within 30 minutes, more preferably within 10 minutes, still more preferably within 1 minute, and most preferably within 10 seconds, and the delay of the signal or the command converging within this range is included in the behavior of the plurality of devices that have been subjected to the scenization.

(evaluation of the effect of partitioning by one test example)

The present inventors reproduced scene 1 by performing the illumination of the illumination light and the output of the audio content, and divided the scene. Then, the effect of dividing the area, that is, the division is evaluated. Next, the results of the one test example will be described.

< evaluation results of illuminance and volume of space in scene 1 >

One experimental result of the illumination and volume of the space in scene 1 is illustrated. Fig. 5 is a schematic diagram illustrating information of the irradiation light irradiated by each of the lighting devices 3 and 5 and information of the sound output by each of the speakers 9a to 9d when the scene 1 is reproduced. In addition, FIG. 6 is a diagram showing the results of a test example in which illuminance and sound volume of a space were measured using an illuminometer (CL-200: Konika minolta) and a noise meter (SD-2200: FUSO) arranged in such a manner as to straddle a writing desk D03 from the writing desk D12 when reproducing scene 1 in the ABW office 20.

In fig. 6, y1 is a function related to illuminance, and y2 is a function related to sound volume. As described above, in the present disclosure, the centralized control region is defined as follows. As in the present embodiment, when two or more desks having upper surfaces at which the illuminance of the worklight is greater than that of the base light are disposed in a continuous and adjacent manner, and when an arbitrary plane intersecting at least one of the two or more desks among planes including the vertical direction is considered, a line segment area (an area viewed as a line segment in the vertical direction) from one end to the other end of one or more upper surfaces of one or more desks at which the plane intersects is defined as the centralized control area. In addition, unlike the present embodiment, when the table having the upper surface on which the illuminance of the worklight is greater than that of the base light is not disposed continuously and adjacently but the table having the upper surface on which the illuminance of the worklight is greater than that of the base light is in an isolated state, when an arbitrary plane intersecting the one table is considered, a line segment region (a region which is viewed as a line segment when viewed in the vertical direction) from one end to the other end of the upper surface of the table intersecting the plane is defined as the centralized control region.

In addition, the non-centralized control area is defined as follows. As in the present embodiment, when two or more desks having upper surfaces with illuminance lower than that of the base lamp are disposed in series and adjacent to each other, and when an arbitrary plane intersecting at least one of the two or more desks among planes including the vertical direction is considered, a line segment area (an area viewed as a line segment in the vertical direction) from one end to the other end of one or more upper surfaces of the one or more desks intersecting the plane is defined as the non-centralized control area. In addition, unlike the present embodiment, when the tables having the upper surfaces with the illuminance of the worklight lower than that of the base light are not arranged continuously and adjacently but the tables having the upper surfaces with the illuminance of the worklight lower than that of the base light are in an isolated one state, when an arbitrary plane intersecting the one table is considered, a line segment area (an area which is viewed as a line segment when viewed in the vertical direction) from one end to the other end of the upper surface of the table intersecting the plane is defined as the non-centralized control area.

In addition, the buffer area is defined as an area existing between the centralized control area and the non-centralized control area. The centralized control area, the non-centralized control area, and the buffer area can be clearly determined and defined in a space partitioned by a plurality of lighting fixtures and speakers by using a known illuminometer and a known noise meter. In addition, in the evaluation method of the present disclosure, the evaluation was performed using a table as a typical daily utensil in an office, but it is not necessarily required to use a table actually. For example, it is also possible to evaluate the illuminance, color temperature, sound volume, and the like of a virtual surface set to a predetermined height, to determine the above-described centralized control area, non-centralized control area, and buffer area, and to determine the illuminance, color temperature, sound volume, and the like by using a board or the like provided virtually. According to the above-described method, the effect of the environmental control system of the present disclosure to improve the zoning effect can be generally found on the premise of any furniture/daily appliances in accordance with the gist of space design in the ABW office, not only a so-called worker work table, but also a long table for a conference, a round table for an alternate-activity, a blanket for meditation, a tatami, a bed for nap, a sofa, and the like. That is, the centralized control area used in the above evaluation is defined by a desk (from one end to the other end of the desk), but the centralized control area, the non-centralized control area, and the buffer area can be defined even when there is no desk. For example, the centralized control area and the non-centralized control area may be defined from one end of a round table to the other end, from one end of a flannelette or tatami to the other end, or from one end of a bed or a couch to the other end, and any determination method may be applied to the determination of these areas. In addition, all of the tables, long tables for conferences, round tables for communication activities, flannelette blankets or tatami for meditation, and beds or sofas for nap can be defined as the subordinate concepts of "objects for defining a predetermined horizontal area".

Thus, in the present embodiment, in fig. 6, the range from the edge D12 to the edge D11 is a centralized control region, and the range from the edge D04 to the edge D03 is a non-centralized control region. The range from the edge D11 to the edge D04 is a buffer region. As shown in fig. 6, in the present test example, the illuminance and the volume of the buffer area (corridor) provided between the centralized control area (desk group 1) and the non-centralized control area (desk group 2) were the minimum. In addition, the average illuminance in the buffer area is lower than the average illuminance in the centralized control area and the average illuminance in the non-centralized control area, and the average volume in the buffer area is lower than the average volume in the centralized control area and the average volume in the non-centralized control area. In particular, regarding the illuminance, the average illuminance of each of the centralized control area and the non-centralized control area is 1.8 times or more the average illuminance of the buffer area. Also, in the centralized control area and the non-centralized control area on both sides of the buffer area, different illumination of illumination light and different reproduction of sound contents are performed. In addition, in the centralized control area, illumination light in which the illuminance sharply increases locally on the desk surface can be realized. In the centralized control area, the audio content promoting the concentration of the human is reproduced with a large volume, and in the non-centralized control area, the audio content providing the relaxation and the sense of calm to the human is outputted with a volume about half of the volume outputted in the centralized control area. Therefore, in the present test example, the peripheral region of the centralized control region can be clearly separated (divided) from the peripheral region of the non-centralized control region, and excellent zoning can be realized. Further, by the illumination light and sound contents respectively reproduced in the peripheral region of the centralized control region and the peripheral region of the non-centralized control region, it is possible to set the peripheral region of the centralized control region as an excellent centralized space in which a person is particularly apt to concentrate on a job, and on the other hand, it is possible to set the peripheral region of the non-centralized control region as a co-creation space in which a person is particularly apt to feel a sense of relaxation and which is also excellent in that a plurality of persons communicate.

Further, it is preferable that the division into areas can be performed clearly if the average illuminance of each of the centralized control area and the non-centralized control area is 1.5 times or more the average illuminance of the buffer area, and the division can be performed further clearly if the average illuminance of each of the centralized control area and the non-centralized control area is 2 times or more the average illuminance of the buffer area, and therefore, it is preferable that the division can be performed most clearly if the average illuminance of each of the centralized control area and the non-centralized control area is 3 times or more the average illuminance of the buffer area. As shown in fig. 6, if the maximum volume of the centralized control area is equal to or more than 2 times the minimum volume of the buffer area, and the maximum volume of the non-centralized control area is smaller than the maximum volume of the centralized control area and larger than the maximum volume of the buffer area, it is preferable to perform the division more clearly.

This is because the following is found: by not making the centralized control area and the non-centralized control area continuously adjacent to each other but intentionally providing an area lower than the illuminance and the sound volume therebetween, the feeling of cognitive distinction between the centralized control area and the non-centralized control area and the feeling of reality when the user sits on the seat are significantly different from each other, that is, an excellent zoning effect is exhibited. In a conventional office scene, areas such as desks and aisles are generally illuminated with high uniformity of color temperature and illuminance distribution. In contrast, the present disclosure uses such an illumination technique and control method, and therefore, particularly in an ABW office scene, a significant effect that is unexpected from conventional knowledge of illumination can be achieved.

In addition, in one test example of the present disclosure, the division is performed with the intention of such a centralized control area and a non-centralized control area, but each area is not necessarily limited to such an intention, and may be applied to a space intended for other action purposes, such as a conference area and a snooze area. In this case, it is preferable to select a lighting condition or a sound condition having a role suitable for each action purpose. It is apparent that an appropriate effect on the partitioning effect by providing the above-described buffer area can be generally found regardless of the kind of the area applied.

In the embodiment of the present disclosure, the characteristic of the illuminance distribution in the centralized control region is greatly different from the characteristic of the illuminance distribution in the non-centralized control region in the curve of y1 shown in fig. 6, that is, the distribution in which a trapezoidal curve is drawn in the non-centralized control region, whereas the distribution in which a curve having two sharp peaks is drawn in the centralized control region is also characterized. This extreme difference contributes significantly to the recognition of the appearance of the space, in particular, significantly improving the zoning effect described above. In addition, control may be used in which the color temperature of the base lamp 3 or the spotlight 5 is different between the centralized control area and the non-centralized control area. In this case, it contributes to the recognition of the appearance, and the partitioning effect described above is easily improved.

(construction and effect of the Environment control System of the present disclosure)

In the above, the control in the environmental control system 10 and the specific mode of each structure are explained. In this item, the essential configuration and the operational effects of the environment control system 10, and the configuration and the operational effects that are preferably employed will be described as apparent from the above description.

< essential Structure and Effect derived from the Structure >

The environment control system 10 includes: one or more spot lights (work lights) 5 for illuminating the upper surfaces of the tables D01 to D14 in the ABW office (room) 20 in which the plurality of tables D01 to D14 are arranged; one or more base lamps 3 for illuminating an area in the ABW office 20, which area is larger than the upper surface; one or more speakers 9 for outputting sound into the ABW office 20; and a control device 61. Here, the environment control system 10 preferably includes a plurality of work lights (spotlights 5), a plurality of base lights 3, and a plurality of speakers 9. The control device 61 performs the following divisional control in which dimming and toning control is performed on one or more spot lights 5 and one or more base lights such that a concentrated control area and a non-concentrated control area are generated with a buffer area interposed therebetween, the concentrated control area being an area in which the illuminance of the spot light 5 is greater than that of the base light 3, and the non-concentrated control area being an area in which the illuminance of the spot light 5 is less than that of the base light 3. Also, in the zone control, the average illuminance in the buffer area is lower than the average illuminance in the centralized control area and the average illuminance in the non-centralized control area, and the average sound volume in the buffer area is lower than the average sound volume in the centralized control area and the average sound volume in the non-centralized control area. The environment control system may include only one control device, or may include two or more control devices.

Therefore, as described in detail above, the centralized control area and the non-centralized control area can be divided, the centralized control area can be set to an excellent centralized space in which the centralized control area is easily centralized for the work, and the peripheral area of the non-centralized control area can be set to an area in which the sense of relaxation is particularly easily felt and which is excellent also in that a plurality of people perform communication.

< selection of a plurality of preferable configurations and effects derived from the respective configurations >

In the divisional control, the content of the sound output at the maximum volume in the centralized control area may be different from the content of the sound output at the maximum volume in the non-centralized control area. In this way, the partitioning effect can be further improved. Further, by comparing the frequency characteristics of the contents obtained by fourier transforming the data of the acoustic waveform used in each region, it is possible to determine whether or not the contents are different. Further, the output of sound of the present disclosure does not provide a person with favorite music to improve the performance of the person, and it is not possible to provide sound to the person using earphones, headphones. This is because, even if a person is provided with sound using headphones or headphones, the region cannot be divided.

According to this configuration, contents such as a rippling watermark of a brook or a television sandstorm sound having characteristics close to those of a sound called white noise or brown noise are output to the centralized control area, whereby the centralized control area can be set to an area where the centralized control area is more easily centralized in the work. Further, by outputting contents that facilitate a sense of relaxation and smooth communication of a plurality of persons, for example, jazz music or bosanova music, in the non-centralized control area, the non-centralized control area can be set to an area that is more likely to be subject to a sense of relaxation and is excellent also in communication of a plurality of persons.

In the above-described divisional control, the spectral width in the fast fourier transform of the sound output at the maximum sound volume in the centralized control region is wider than the spectral width in the fast fourier transform of the sound output at the maximum sound volume in the non-centralized control region. Here, the spectral width refers to a spread width of a wavelength or a frequency of a spectral line, and is a difference in wavelength between two wavelengths whose intensity falls below a predetermined width (for example, 1/2, 1/10, or the like) from a maximum value, and may be expressed by a frequency. The spectral width at half maximum (in the spectral distribution of the light output, the width of a wavelength at which the relative emission intensity is 50% of the peak) may be used to define the spectral width.

According to this configuration, the effect of easily improving the efficiency of the concentrated work by the lighting and the effect of easily improving the efficiency of the concentrated work by the sound can be superimposed, and the concentrated control area can be changed to the area of easily remarkably improving the efficiency of the concentrated work by the additive effect of the superimposition. In the non-centralized control area, the effect of easy enhancement of relaxation feeling and communication by lighting and the effect of easy enhancement of relaxation feeling and communication by voice can be superimposed. Thus, the non-centralized control region can be changed to a region that is likely to be particularly relaxed and particularly likely to communicate by the superimposed complementary effect.

In addition, the average illuminance of each of the centralized control region and the non-centralized control region may be 1.8 times or more the average illuminance of the buffer region. In the present disclosure, the centralized control area and the non-centralized control area are defined using any plane intersecting one or more tables among planes including the vertical direction. Here, it is sufficient that at least one of the planes satisfying the requirement is present, as long as the requirement that the average illuminance of each of the centralized control area and the non-centralized control area is 1.8 times or more the average illuminance of the buffer area.

According to this configuration, the area division effect of dividing the centralized control area into the non-centralized control area by the buffer area can be made remarkable.

As an example, when two of the cases are described in more detail, for example, in the above-described embodiment, an omnidirectional camera may be further provided above the vicinity of the entrance of the ABW office 20. As shown in the flowchart of the control shown in fig. 7 (a), when the environment control system 10 is installed in the ABW office 20 and the environment control system 10 is driven, the control device 61 may determine whether or not the number of people in the ABW office 20 is equal to or greater than a predetermined number of people based on a signal from the omnidirectional camera based on wireless or wired transmission in step S1.

When a negative determination is made in step S1, the process proceeds to step S2 to reproduce scene 1 shown in fig. 2, whereas when an affirmative determination is made in step S1, the process proceeds to step S3 to reproduce scene 3 shown in fig. 2, and thereafter, the control may be returned to repeat the steps from step S1 to the following steps.

According to this control, for example, on a day when the demand for the integrated space is high, such as a day when the office is busy, scene 3 can be automatically reproduced, the number of seats in the integrated control area in the office can be increased from 8 to 14, and the demand for the integrated space by the worker can be satisfied, which results in an improvement in the work performance of the worker and the organization.

In the above-described embodiment, the storage unit 61c of the control device 61 may be provided with a storage unit for storing light control information related to light control for a predetermined period (date and time) between the spotlight 5 and the base lamp 3. The control device 61 may perform dimming control of each spotlight 5 and each base lamp 3 based on the light control information.

More specifically, for example, as shown in the flowchart of the control shown in fig. 7 (b), when the environment control system 10 is installed in the ABW office 20 and the environment control system 10 is driven, the control device 61 may determine whether or not the predetermined period is reached based on information from a built-in timer in step S11. Here, the predetermined period can be set to, for example, a leisure day.

When a negative determination is made in step S11, the process proceeds to step S12 to reproduce scene 1 shown in fig. 2, whereas when an affirmative determination is made in step S11, the process proceeds to step S13 to reproduce scene 4 shown in fig. 2, and thereafter, the control may be returned to repeat the steps from step S11 to the following steps.

According to the present modification, in the case of a leisure day, scene 4 is automatically reproduced. In this way, in the case of a leisure day, the number of seats in the centralized control area can be set to 0, and the number of seats in the non-centralized control area can be set to 14.
