In addition, the size of each member in the figure is appropriately emphasized for ease of explanation, and does not indicate the actual size or the ratio between the members.
Further applicable areas will become apparent from the description herein. The description and examples of this summary are intended for purposes of illustration only and are not intended to limit the scope of this disclosure.

With reference to FIG. 1, reference numeral 1 denotes a basic block diagram of a lighting control system. The lighting control system 1 has a control unit 11, a measurement unit 12, a storage unit 13, a reception unit 14, and a lighting fixture 15 as main components.

The measuring unit 12 detects a change in the environment in a predetermined area, measures the changed state of the environment, and provides numerical data obtained.

The measurement unit 12 is composed of, for example, a sensor that detects a change in the environment in the predetermined area and generates a detection result as numerical data. The sensor detects a change in the environment in the predetermined region at a frequency of, for example, about once every few minutes, and generates the numerical data each time it is detected. Here, the predetermined area is a space where the user can stay for a certain period of time, and refers to a place where the indoor environment may change with the passage of time, typically a conference room, a classroom, or the like. Applicable.

The storage unit 13 sets quantitative data indicating the state of the environment step by step, and stores control data for controlling at least one of the light amount or hue / saturation of the lighting fixture 15 in correspondence with each quantitative data. .. In the quantitative data, the minimum value to the maximum value of the numerical data that may be provided by the measuring unit 12 are set stepwise.

The control data is data for quantitatively setting the light amount or hue / saturation of the luminaire 15 and distributing the light of the luminaire 15 with a predetermined light amount or hue / saturation. Then, the storage unit 13 stores a table in which the quantitative data set in stages and the control data corresponding to each quantitative data are uniquely associated with each other.

The receiving unit 14 receives the numerical data provided by the measuring unit 12. The transmission of the numerical data from the measuring unit 12 to the receiving unit 14 may be either wired or wireless.

The control unit 11 searches the storage unit 13 for quantitative data corresponding to the numerical data received by the reception unit 14, and reads out the control data corresponding to the searched quantitative data. Then, based on the read control data, the lighting fixture 15 installed in the predetermined region is controlled to distribute light with a specific amount of light and / or output of hue / saturation.

The luminaire 15 has a network function capable of receiving the control data from the control unit 11 and adjusting the amount of light, hue, and saturation. As the light source, an LED bulb is preferable.

FIG. 2 is a specific device configuration diagram of the lighting control system 1. The sensor constituting the measuring unit 12 detects at least one of temperature, humidity, carbon dioxide concentration, total volatile organic compound (TVOC), dust (PM2.5), and atmospheric pressure in the predetermined region. All you need is. These sensors detect the detection target at regular intervals. When using a plurality of units, the unique ID of each sensor may be transmitted together with the numerical data.

The receiving unit 14 may be any as long as it corresponds to a communication protocol for transmitting the numerical data generated by the measuring unit 12. In particular, the lighting control system 1 disclosed in the present specification must receive numerical data from the sensor at regular intervals, assuming a sensor module of an equipment system installed in a plurality of conference rooms such as a building. Therefore, it is preferable that the data consumption is maintained-free by suppressing the power consumption as much as possible, and the communication distance is relatively long even if the data rate is low. For example, energy harvesting wireless communication (EnOcean) is suitable.

As described above, the control unit 11 transmits control data from the reception unit 14 to the luminaire 15 side based on the numerical data provided by the communication protocol on the measurement unit 12 side, but the luminaire 15 side does not. It may be connected to a network with a communication protocol different from the communication protocol. Therefore, in the present embodiment, the control unit 11 is configured to include the intelligent controller 11A that functions as a multi-protocol gateway as the main body unit.

In the embodiment of FIG. 2, the storage unit 13 is provided in the intelligent controller 11A, but a separate storage device may be connected to the storage unit 13.

Further, in the present embodiment, the control unit 11 is externally connected to the converter 11B for converting into a communication protocol that can be received on the lighting fixture 15 side. For example, control data is transmitted from the intelligent controller 11A to the converter 11B by http (HyperText Transfer Protocol), converted into a communication protocol that can be received by the luminaire 15 by the converter 11B, and the luminaire 15 is controlled. For example, when managing a large number of lighting fixtures 15 in one building, the communication protocol may be a low power consumption wireless sensor network, that is, a wireless PAN (Personal Area Network). Specifically, a single network to which a large number of nodes can be connected is preferable.

The luminaire 15 is installed in a predetermined area R (for example, a conference room). The amount of light and hue / saturation are adjusted by the control data. Here, the "light amount" of the lighting control system disclosed in the present specification is a time integral amount of a luminous flux, and indicates the brightness of the lighting fixture itself. Further, "hue" refers to a difference in color appearance such as color and hue, and "saturation" refers to a measure of color vividness.

FIG. 3 is a modified example of the embodiment of FIG. In this modification, various adjustment devices and warning devices are connected to the control unit 11. These adjusting devices and warning devices operate in conjunction with the adjustment of the light intensity, hue, and saturation of the lighting fixture 15 in order to return to a good state when the environment of the predetermined region R deteriorates. That is, in these adjusting devices and warning devices, when the numerical data obtained by the measuring units 12A and 12B exceeds a predetermined threshold value, the control unit 11 obtains the numerical data in the predetermined area R. Accepts adjustment device control data and warning device control data for changing to a predetermined threshold value or less.

For example, when the measuring unit 12 measures the carbon dioxide concentration in the predetermined region R by the carbon dioxide concentration sensor, when the carbon dioxide concentration reaches the concentration requiring ventilation, the control unit 11 reaches the concentration. Warning to read the corresponding control data and to activate the control device that ventilates the predetermined area R in order to reduce the concentration, and / or to promote the ventilation of the control device control data and / or the predetermined area R. Generate warning device control data to operate the device.

In this modification, the adjusting device is a ventilation fan 16, a total heat exchanger 17, and a smoke exhaust device 18, and the warning device is a rotating light 19. The warning device may also be a buzzer, a display, or the like (not shown).

In this modification, the control unit 11 controls the physical input / output between the intelligent controller 11A, the ventilation fan 16, the total heat exchanger 17, the smoke exhaust device 18, and the rotary lamp 19. , 11D, 11E, 11F are interposed to transmit the adjustment device control data and the warning device control data.

FIG. 4 is an example of a table in which the hue and saturation of the lighting equipment stored in the storage unit 13 are set. This example is a table when the measuring unit 12 is provided with a carbon dioxide concentration sensor. The table is composed of carbon dioxide concentration, hue (color temperature), and saturation. As described above, the storage unit 13 sets quantitative data indicating the state of the environment step by step. In this example, the quantitative data of the carbon dioxide concentration in the room is set in 7 steps in the range of "~ 800 ppm ~" to "1500 ppm ~". Then, the hue value (color temperature value in this example) and the saturation value are uniquely associated with each stage. The remarks column shows specific color names in text.

FIG. 5 is a diagram schematically showing changes in hue and saturation of a lighting fixture corresponding to the carbon dioxide concentration in the table of FIG. In this embodiment, an example of measuring the carbon dioxide concentration in the classroom where the lecture is given is shown. In the drawing view, the horizontal axis from left to right is the time axis. The measuring unit 12 periodically provides numerical data of the carbon dioxide concentration. The carbon dioxide concentration at the start of the lecture was 650 ppm, 920 ppm after 15 minutes, 1480 ppm after 20 minutes, 2150 ppm after 45 minutes, 890 ppm after 55 minutes, and 720 ppm after 60 minutes (actually, in the measurement unit 12, for example, for example. Numerical data is provided every two minutes, but in FIG. 5, only the time when the change is remarkable is picked up and displayed). The lecture is completed in 45 minutes. For reference, the degree of experience is described in each measured value. At the start of the lecture, it is "comfortable", but at 20 minutes (1480 ppm) it becomes "normal", and at 45 minutes (2150 ppm) at the end of the lecture, it becomes "dirty". In light of the table of FIG. 4, the control content of the luminaire 15 is that the hue value is 65535 and the saturation value is 150 at the time of 20 minutes, but the hue value is 65535 and the saturation value is 65535 at the time of 45 minutes. The degree value is 254. Therefore, the output of the luminaire 15 is controlled to "red (light)" 20 minutes after the start of the lecture and to "red (dark)" 45 minutes. In the present embodiment, the configuration for changing the hue / saturation of the lighting fixture 15 has been described, but the configuration for changing the light amount of the lighting fixture 15 and the configuration for changing the light amount and the hue / saturation may be used.

By the way, in the case of buildings, the carbon dioxide concentration is maintained at 1000 ppm or less according to the Ministry of Health, Labor and Welfare and the building environmental hygiene management standards, and in the case of educational facilities, it is maintained at 1500 ppm or less according to the Ministry of Education, Culture, Sports, Science and Technology and school environmental hygiene standards. It is stipulated to do. It is said that the higher the carbon dioxide concentration, the lower the function (performance) of the human brain. When a person stays in a closed space, at least by exhalation, the concentration of carbon dioxide in the space gradually increases. Therefore, ventilation in a closed space (indoor) is required. For example, if ventilation is instructed by a text display or a warning sound on a display or the like, there is a risk of hindering concentration in lectures, meetings, and the like. Therefore, the lighting control system 1 disclosed in the present specification is designed to control the hue, saturation, and the like of the lighting in the room so as to change according to the change of the carbon dioxide concentration.

In addition, the control data may be set to continuously change the gradation value of the light amount, the hue, and the saturation with respect to the stepwise setting of the quantitative data. With such a setting, it is possible to casually suggest indoor ventilation without disturbing the concentration on lectures, meetings, and the like.

Further, the hue and saturation for the stepwise setting of the quantitative data are not limited to the settings as shown in FIG. However, in order to intuitively understand the need for ventilation, for example, the hue of the luminaire 15 changes from a cold color to a warm color and from a dull color each time the stage of the numerical data of the carbon dioxide concentration goes up. Ventilation can be smoothly promoted by setting the gradation value to be changed to a vivid color, that is, setting to change the gradation value.

In FIGS. 4 and 5, an example of changing the hue and saturation based on the numerical data obtained by measuring the carbon dioxide concentration has been described, but the numerical data obtained by another measuring unit (sensor) has been described. The control data may be acquired based on the above. Further, as described with reference to FIG. 3, the operation of the adjusting device such as the ventilation fan 16 and the warning device may be linked. For example, when the threshold value of the carbon dioxide concentration is set to 1101 ppm, the control unit 11 controls the luminaire 15 with the hue 60000 and the saturation 150 and the ventilation fan when the stage corresponds to the stage of 1101 ppm to 1200 ppm in FIG. It may be configured to generate control device control data for activating 16 and initiate ventilation. As described above, by linking the light distribution control of the lighting fixture 15 and the start / stop control of the adjusting device, it is possible to maintain a good indoor environment without hindering the concentration on meetings and lectures. ..

FIG. 6 is a control flow diagram of the lighting control method disclosed in the present specification. In the description of the control flow, the symbols of the lighting control system 1 disclosed in FIGS. 1 to 5 are appropriately used.

At the time of lighting control, the control unit 11 first receives the state value of the lighting fixture 15 from the lighting fixture 15 side (S1). More specifically, the intelligent controller 11A receives the state value of the luminaire 15 via the converter 11B.

When the lighting fixture 15 is not distributed, that is, when it is OFF (NO in S2), the lighting control ends. On the other hand, when the lighting fixture 15 is light-distributed, that is, when it is ON (YES in S2), the measuring unit 12 detects a change in the environmental state in the room and measures the changed environmental state. Numerical data is provided to the control unit 11 (S3).

The control unit 11 receives the numerical data in the reception unit 14 (S4). The control unit 11 searches for the quantitative data of the storage unit 13 corresponding to the numerical data received by the receiving unit 14, and reads out the control data corresponding to the searched quantitative data (S5). The storage unit 13 sets quantitative data indicating the state of the indoor environment step by step, and sets control data in advance to control at least one of the light amount and the color tone of the lighting fixture in correspondence with each quantitative data. I remember. The control data may correspond to the stepwise setting of the quantitative data so as to continuously change the light intensity or the gradation value of hue / saturation. Further, when the numerical data exceeds a predetermined threshold value, the control data is read out and the control device control data for operating the control device for changing the numerical data in the room to the predetermined threshold value or less is generated. You may do so.

The read control data is transmitted to the luminaire 15 (S6). More specifically, the control data is transmitted from the intelligent controller 11A to the converter 11B by, for example, http, converted into a communication protocol receivable by the luminaire 15 by the converter 11B, and then. It is transmitted to the luminaire 15. The lighting fixture 15 distributes light in the room by controlling the output of the amount of light or the hue / saturation by the control data (S7).

FIG. 7 is a diagram showing a lighting control system 1 installed in a plurality of conference rooms. In the lighting control system 1 disclosed in the present specification, when a plurality of lighting fixtures 15 are arranged in a plurality of regions, the output of the plurality of lighting fixtures 15 is based on the numerical data measured in each region. Can also be controlled individually.

That is, the intelligent controller 11A receives numerical data from the measurement unit 12 installed in the conference room A and the measurement unit 12 installed in the conference room B. As described above, the measurement unit 12 transmits the unique ID of each sensor together with the numerical data. The storage unit 13 (not shown in FIG. 7) stores a table in which quantitative data and corresponding control data are associated with each of the conference room A and the conference room B. In the present embodiment, there is a user in the conference room A, but there is no user in the conference room B. Therefore, when the measuring unit 12 is a carbon dioxide concentration sensor, the numerical data of the conference room B does not change, but the numerical data of the conference room A rises, and the color of the lighting fixture 15 changes and the light is distributed. Become.
