Description

  The present invention relates to a lighting system.

  Currently, many lighting devices are provided with a remote controller, and can be operated remotely by radio. However, many of these controllers are intended for individual operations of lighting devices. Therefore, if it is going to operate a some illuminating device collectively using these controllers, the operation will become very complicated.

  On the other hand, in recent years, paying attention to the widespread use of communicable general-purpose devices such as smartphones, lighting devices that can be operated from these general-purpose devices have been sold. Since these are usually operated by an application installed in a general-purpose device, by devising this application, it becomes relatively easy to operate a plurality of lighting devices.

  However, communication standards such as Wi-Fi (registered trademark) and Bluetooth (registered trademark) adopted by these general-purpose devices are intended for short-range communication, and are often vulnerable to obstacles such as walls. Therefore, it is problematic in terms of reliability to adopt for operation of a plurality of lighting devices arranged in a large store or the like.

  Hereinafter, an illumination system according to an embodiment of the present invention will be described with reference to the drawings.

[First Embodiment]
First, the outline | summary of the illumination system 100 which concerns on 1st Embodiment is demonstrated, referring FIG.
As illustrated in FIG. 1, the illumination system 100 includes a plurality of illumination devices 101 to 113 having a light source, and a tablet 121 that is a control device that operates the illumination devices 101 to 113. The illumination system 100 is a system that can operate a plurality of illumination devices 101 to 113 from a single tablet 121. In this embodiment, various lighting devices can be used in addition to the pendant light indicated by 101 to 104, the downlight indicated by 105 to 108, the ceiling light indicated by 109 to 112, and the bracket light indicated by 113. In this embodiment, in addition to the tablet indicated by 121, a dedicated controller or a control device such as a smartphone can be used.

  Each of the lighting devices 101 to 113 and the tablet 121 has a communication function compliant with Bluetooth. The lighting devices 101 to 113 and the tablet 121 constitute a mesh network having these as nodes. Hereinafter, a lighting device, a control device, or the like that is a node may be generally referred to as a “terminal device”. In addition, a lighting device other than the control device among the terminal devices may be referred to as a “controlled device”. Adjacent terminal apparatuses are connected by a connection in which one is a central (master) and the other is a peripheral (slave). As a result, these terminal devices can perform two-way wireless communication. In FIG. 1, a bent arrow indicates a connection, and a terminal device on the start point side of an arrow marked “C” is a central terminal, and a terminal device on the end point side of an arrow marked “P” is a peripheral. For example, the lighting devices 101 and 102 are connected by a connection C12 in which the lighting device 101 is a central and the lighting device 102 is a peripheral. In the present embodiment, the control device operates only as a peripheral, and the controlled device operates as both a central and a peripheral.

  Each of the terminal devices 101 to 113 and 121 has a group ID (first identifier) and a device ID. The group ID is a value assigned in common to all terminal devices participating in the same network. By using this group ID when forming a network, terminal devices having different group IDs can be excluded from the network. If this is used, for example, a terminal device installed in a certain user's store or the like and a terminal device owned by a third party can be separated on a network basis. The device ID is a local address for identifying the terminal device in the network. Therefore, terminal devices belonging to different networks may have the same device ID. In data communication, which will be described later, a device ID is included in data for specifying a transmission destination. In many cases, however, the device ID has a shorter bit length than a MAC address or the like, so the amount of data communication is reduced. be able to. In FIG. 1, the group ID and device ID of each terminal device are shown in parentheses in the format “group ID-device ID”. For example, the lighting device 101 has a group ID = A and a device ID = 1. In the case of FIG. 1, the terminal devices 101 to 113 and 121 surrounded by a broken line a111 have the same group ID = A and constitute one network. On the other hand, terminal devices 151 and 152 having different group ID = B are excluded from this network.

Next, a data flow between terminal devices of the lighting system 100 will be described.
As a first example, a case where the lighting device 113 (first lighting device) is controlled from the tablet 121 (first control device) will be described with reference to FIG.
In this case, first, the user operates an application on the tablet 121 to instruct the light color and brightness of the light source of the illumination device 113. Then, the tablet 121 generates control data Dc (first data) for controlling the light source of the illumination device 113. The control data Dc includes at least a device ID = 13 of the lighting device 113 to be controlled and a value indicating the control content. Subsequently, the tablet 121 transmits control data Dc to the lighting device 113. Here, when the tablet 121 and the lighting device 113 are arranged at a distance from each other and direct data communication is not possible, the tablet 121 uses the plurality of connections in the network to transmit the control data Dc to the lighting device 113. Will be sent. In the case of FIG. 2, the control data Dc generated by the tablet 121 is transmitted to the connection CN1z having the tablet 121 as a peripheral and the lighting device 101 as a central, as indicated by a white arrow. Thereafter, the data is sequentially transmitted to the illumination device 101 → connection CN15 →... → connection CNbc → illumination device 112. Thereafter, the data is transmitted to the lighting device 113 via the connection CNcd with the lighting device 112 as the central and the lighting device 113 as the peripheral. Finally, the illuminating device 113 confirms the control data Dc for itself from the device ID = 13 of the received control data Dc, and controls the light color, brightness, and the like of the light source based on the control data Dc.

As a second example, a case where the lighting device 113 notifies the tablet 121 of the state of the lighting device 113 will be described with reference to FIG.
In this case, first, the lighting device 113 generates state data Ds (second data) for notifying the tablet 121 of the light color, brightness, and the like of the light source that the lighting device 113 has. The state data Ds includes at least a device ID = 21 of the tablet 121 to be notified and a value indicating the state of the lighting device 113. Subsequently, the lighting device 113 transmits the state data Ds to the tablet 121 using a plurality of connections in the network, as in the first example. In the case of FIG. 2, as indicated by the black arrows, the state data Ds generated by the lighting device 113 is transmitted to the connection CNcd having the lighting device 113 as a peripheral and the lighting device 112 as a central. Then, it transmits in order to the illuminating device 112-> connection CN8c->...-> connection CN12-> illuminating device 101. FIG. Thereafter, the data is transmitted to the tablet 121 via the connection CN1z in which the lighting device 101 is the central and the tablet 121 is the peripheral. Finally, the tablet 121 confirms the state of the lighting device 113 from the received state data Ds, displays this information on the screen, or generates new control data Dc for the lighting devices 101 to 113 using this information. Or

  As described above, according to the present embodiment, even when the lighting device and the control device are arranged at a distance from each other and are outside the Bluetooth communication range, a plurality of them can be used as long as they belong to the same network. By using this connection, data communication between the lighting device and the control device becomes possible.

  Furthermore, in the case of the present embodiment, the network does not necessarily have to be a mesh type, but by constructing a mesh type network as shown in FIG. 1, a plurality of routes are used for data communication between terminal devices. Can do.

  For example, it is assumed that some failure has occurred in the connection CN9a between the lighting devices 109 and 110 as indicated by white crosses in FIG. Even in this case, a route that does not pass through the connection CN 9a, for example, the tablet 121 →... → lighting device 105 → connection CN56 → lighting device 106 → connection CN67 → lighting device 107 → connection CN7b → lighting device 111 →. -> Control data Dc can be transmitted from the tablet 121 to the lighting device 113 by using the route of the lighting device 113.

  That is, as shown in FIG. 1, by making the network a mesh type, the fault tolerance of data communication can be made higher than when terminal devices are connected by a star type or line type network.

Next, a network forming process of the lighting system 100 will be described with reference to FIGS.
First, as illustrated in FIG. 4, the lighting device 101 indicated by a broken line a <b> 121 operates as a central and starts scanning SC <b> 1. On the other hand, the other terminal devices 102 to 113, 121, 151, and 152 operate as peripherals and send out advertising. Here, the advertising includes at least the group ID of the transmission source. For example, the advertising AD2 of the lighting device 102 includes the group ID = A, and the advertising AD1 ′ of the lighting device 151 includes the group ID = B. Subsequently, when the illuminating device 101 detects the advertising AD2 of the illuminating device 102 within the range of the scanning SC1, as shown in FIG. 5, the illuminating device 101 confirms a match of global ID = A from the advertising AD2. The lighting device 102 is connected to the lighting device 102 by a connection CN12 that uses the lighting device 102 as a peripheral. Similarly, the illuminating device 105 and the tablet 121 within the range of the scanning SC1 of the illuminating device 101 are also connected to the illuminating device 101 through connections CN15 and CN1z using these as peripherals.

  Subsequently, as illustrated in FIG. 6, the illumination device 102 indicated by a broken line a131 connected to the illumination device 101 operates as a central to start scanning SC5. Subsequently, when the lighting device 102 detects the advertising AD3, AD6 of the lighting devices 103, 106 within the range of the scanning SC2, the lighting device 102 confirms the match of the group ID = A from these advertising AD3, AD6, The lighting devices 103 and 106 are connected by connections CN23 and CN26 which are peripherals. Similarly, the illuminating devices 106 and 109 that are within the scanning SC5 range of the illuminating device 105 indicated by the broken line a132 connected to the illuminating device 101 and have the group ID = A are also connected by the connections CN56 and CN59 having these as peripherals. Is done.

  Subsequently, as illustrated in FIG. 7, the illumination device 103 indicated by a broken line a141 connected to the illumination device 102 operates as a central and starts scanning SC3. Subsequently, the illuminating devices 104 and 107 having the group ID = A within the range of the scanning SC3 are connected to the illuminating device 103 by the connections CN34 and CN37 that use them as peripherals. Similarly, the lighting devices 107 and 110 having the group ID = A within the range of the scanning SC6 of the lighting device 106 indicated by the broken line a142 connected to the lighting devices 102 and 105, and connections CN67 and CN6a having these as peripherals Is connected to the lighting device 106. Further, the illumination device 110 having the group ID = A within the range of the scanning SC9 of the illumination device 109 indicated by the broken line a143 connected to the illumination device 105 is connected to the illumination device 109 by the connection CN9a using this as a peripheral. The

  Subsequently, as illustrated in FIG. 8, the illumination device 104 indicated by a broken line a151 connected to the illumination device 103 operates as a central to start scanning SC4. Subsequently, the lighting device 108 within the range of the scanning SC4 and having the group ID = A is connected to the lighting device 104 by the connection CN 48 using this as a peripheral. Similarly, the lighting devices 108 and 111 having the group ID = A and within the range of the scanning SC7 of the lighting device 107 indicated by the broken line a152 connected to the lighting devices 103 and 106 are connected to the connections CN78 and CN7b. Is connected to the lighting device 107. In addition, the illuminating device 111 having the group ID = A within the range of the scanning SCa of the illuminating device 110 indicated by the broken line a153 connected to the illuminating devices 106 and 109 is connected to the illuminating device 110 by the connection CNab using this as a peripheral. Connected.

  Subsequently, as shown in FIG. 9, the lighting device 108 indicated by a broken line a161 connected to the lighting devices 104 and 107 operates as a central, and starts scanning SC8. Subsequently, the illuminating device 112 within the range of the scanning SC8 and having the group ID = A is connected to the illuminating device 108 by the connection CN8b using this as a peripheral. In addition, the illuminating device 112 having the group ID = A within the range of the scanning SCb of the illuminating device 111 indicated by the broken line a152 connected to the illuminating devices 107 and 110 is also connected to the illuminating device 111 by the connection CNbc using this as a peripheral. Connected.

  Subsequently, as shown in FIG. 10, the illuminating device 112 indicated by a broken line a171 connected to the illuminating devices 108 and 111 operates as a central, and starts scanning SCc. Subsequently, the illuminating device 113 within the range of the scanning SCc and having the group ID = A is connected to the illuminating device 112 through the connection CNcd using this as a peripheral. On the other hand, the illuminating device 151 that is within the scanning SCc but has a different group ID = B is not connected to the illuminating device 112 as indicated by the white cross mark.

Finally, as shown in FIG. 11, the illuminating device 113 indicated by a broken line a181 connected to the illuminating device 112 operates as a central, starts scanning SCd, and detects the advertising AD2 ′ of the illuminating device 152. However, since the lighting device 152 has a different group ID = B, it is not connected to the lighting device 113 as indicated by white crosses.
With the above, a network of the lighting system 100 shown in FIG. 1 is formed.

Next, the effect of the illumination system 100 according to the present embodiment will be described using an illumination system 100 ′ according to a comparative example.
FIG. 12 is a diagram illustrating an outline of a lighting system according to a comparative example.
Similarly to the illumination system 100, the illumination system 100 ′ also includes illumination devices 101 to 113 and a tablet 121 that operates the illumination devices 101 to 113. However, in the case of the illumination system 100 ′, unlike the illumination system 100, the illumination device 101 and the tablet 121 are connected by a connection CNz1 in which the tablet 121 is a central and the illumination device 101 is a peripheral. Moreover, the connection by Bluetooth is not established between the illuminating devices 101-113, and communication between these illuminating devices 101-113 is implement | achieved using the advertising.

  For example, when the lighting device 113 is controlled from the tablet 121, first, the tablet 121 generates and outputs control data Dc including a control target and control content. Subsequently, the lighting apparatus 101 that has received the control data Dc transmits an advertising AD1 including the control data CD. Subsequently, the lighting device 105 that has detected the advertising AD1 by the scanning SC5 transmits the advertising AD5 including the control data CD. Thereafter, as shown by the white arrow, by advertising and scanning of each lighting device, such as scanning SC9 of advertising AD5 of lighting device 105 by lighting device 109, scanning SCa of advertising AD9 of lighting device 109 by lighting device 110, etc. Then, the control data Dc is propagated to the lighting device 113. As a result, in the illumination system 100 ′ as well, the illumination device 113 can be remotely operated by the tablet 121, as in the illumination system 100.

However, in the case of the illumination system 100 ′, the following problem occurs.
In the wireless communication by Bluetooth, the 2.4 GHz band is used. This frequency band is also used in Wi-Fi and Zigbee (registered trademark) in addition to Bluetooth, and is widely used in general electronic devices. In order to avoid interference with other electronic devices, Bluetooth has a hopping function in which a frequency band is divided into predetermined frequency widths and these are switched and used.

  Specifically, as shown in FIG. 13, 40 channels from 0 to 39 are prepared for every 2 MHz in Bluetooth. However, among these, only three channels 37 (center frequency 2402 MHz), 38 (center frequency 2426 MHz), and 39 (center frequency 2480 MHz) shown by shading can be used for advertising. In other words, in the case of the illumination system 100 ′, there is a problem in that there is little room for channel selection by the hopping function, and interference from other electronic devices or the like is likely to occur.

  In that respect, in the illumination system 100, once communication is established, data communication between terminal devices is performed. In this connection, 37 channels excluding 37 to 39 can be used. That is, it can be said that the lighting system 100 is less susceptible to the influence of interference from other electronic devices than the lighting system 100 ′.

  Furthermore, the use of a connection that is bidirectional communication not only consumes less power than the case of using data propagation by unilateral advertising, but can communicate larger data without missing it.

  As described above, according to the present embodiment, in a lighting system that remotely operates a lighting device using Bluetooth, a highly reliable lighting system in which influence of interference with other electronic devices in the vicinity is reduced as compared with the comparative example. Can be provided.

[Second Embodiment]
2nd Embodiment demonstrates an illumination system provided with terminal devices other than an illuminating device and a control apparatus.
14-16 is a figure which shows the outline | summary of the illumination system which concerns on this embodiment.
The illumination system 200 illustrated in FIG. 14 is configured by replacing the illumination device 102 with the relay device 202 in the illumination system 100. The relay device 202 does not have a light source like the lighting device, and only relays data communication, and transfers data received from a predetermined connection to another connection. The relay device 202 can switch the operation of both the central and the peripheral, like the lighting device 102 and the like. For example, the relay device 202 does not need a function as lighting, but there is an obstacle such as a wall between the terminal devices, and it is desired to secure a route that bypasses the obstacle, or a route between the terminal devices to ensure redundancy. This is effective when you want to increase the number.

  The illumination system 300 illustrated in FIG. 15 is configured to further include a human sensor device 314 that senses the presence or absence of a predetermined range of people with respect to the illumination system 100. The human sensor device 314 is connected to the lighting devices 108 and 113 by connections CN8e and CNed, for example.

  If this illumination system 300 is used, for example, it is possible to construct a crime prevention system in which the light source of the illumination device is turned on when a person enters the predetermined area. That is, the human sensor device 314 detects the intrusion of a human, and generates and outputs human data Dm (third data) including the device ID = 21 of the transmission destination tablet 121 and the detection result. Then, the human data Dm output from the human sensor device 314 is transmitted to the tablet 121 via the connections CN8e, CN48,..., CN12, and CN1z, as indicated by the black arrows. After that, the tablet 121 that has received the human impression data Dm generates and outputs control data Dc including the device ID = 13 of the lighting device 113 (third lighting device) to be controlled and the control content for turning on the light source. . Then, the control data Dc output from the tablet 121 is transmitted to the lighting device 113 via the connections CN1z, CN15,..., CNbc, and CNcd. Finally, the illumination device 113 turns on the light source based on the control content of the received control data Dc.

  In addition to this example, the light source of the lighting device can be turned off, or the light color and brightness of the light source can be adjusted based on the content of the human impression data Dm. For example, it is possible to construct an energy saving system that turns off the light source of the lighting device when a person leaves a predetermined area.

  Although not shown, a human sensor device with a control function that can control the lighting device is given as a modified example of the human sensor device 314. If this human sensor device with a control function is used, unlike the human sensor device 314, the lighting device on the network by the device itself using the detection result can be used without transmitting the sensing data Dm to the control device. Control becomes possible. As another modified example, there is a lighting device with a human sensor in which a human sensor is added to the lighting device. If this lighting device with a human sensor is used, the light source can be directly controlled by the device itself using the detection result of the human sensor without using a network. In any example, if the human sensitive data Dm can be generated and output based on the sensing result, the same effect as the case where the human sensitive sensor device 314 is used can be obtained.

  The illumination system 400 illustrated in FIG. 16 is configured to further include an illuminance sensor device 415 that detects illuminance within a predetermined range with respect to the illumination system 100. The illuminance sensor device 415 is connected to the lighting device 109 by, for example, the connection CN9f.

  If this illumination system 400 is used, for example, it is possible to construct an energy saving system that adjusts the brightness of the light source of the illumination device in accordance with the brightness of the surroundings. That is, the illuminance sensor device 415 detects illuminance within a predetermined range, and generates and outputs illuminance data Di (fourth data) including the device ID = 21 of the transmission destination tablet 121 and the detection result. The illuminance data Di output from the illuminance sensor device 415 is transmitted to the tablet 121 via the connections CN9f, CN59, CN14, and CN1z, as indicated by black arrows. After that, the tablet 121 that has received the illuminance data Di calculates the brightness according to the illuminance, and the brightness of the light source based on the device ID = 9 of the illumination device 109 (fourth illumination device) to be controlled and the calculation result. The control data Dc including the control content for adjusting the height is generated and output. Then, the control data Dc output from the tablet 121 is transmitted to the illumination device 109 via the connections CN1z, CN15, and CN59. Finally, the illumination device 109 adjusts the brightness of the light source based on the control content of the received control data Dc.

  Although not shown, the illumination system 400 may include a plurality of illuminance sensor devices 415. In this case, the illuminance data Di of the illuminance sensor device 415 is collected in a control device such as the tablet 121. And it is also possible for a control apparatus to calculate the average value etc. which used them, and to control an illuminating device based on the result.

  Moreover, although not shown in figure, the illumination intensity sensor apparatus with a control function which can control an illuminating device as a modification of the illumination intensity sensor apparatus 415 is mentioned. If this illuminance sensor device with a control function is used, unlike the illuminance sensor device 415, the illuminance data Di can be controlled by the device itself using the detection result without transmitting the illuminance data Di to the control device. It becomes possible. As another modified example, an illumination device with an illuminance sensor in which an illuminance sensor is added to the illumination device may be used. If this illumination device with an illuminance sensor is used, it becomes possible to directly control the light source by the device itself using the detection result of the illuminance sensor without using a network. In any example, if the illuminance data Di can be generated and output based on the detection result, the same effect as when the illuminance sensor device 415 is used can be obtained.

  As described above, according to the present embodiment, not only the same effects as those of the first embodiment can be obtained, but also a lighting device, a control device, and various devices such as a relay device, a human sensor device, and an illuminance sensor device are combined. This makes it possible to build a lighting system that is rich in variations.

[Third Embodiment]
In the third embodiment, an illumination system including a plurality of control devices will be described.
First, an outline of an illumination system 500 according to the third embodiment will be described with reference to FIG.
The illumination system 500 is configured to further include tablets 522 to 524 and a controller 525 as control devices with respect to the illumination system 100. Here, the controller 525 is not a general-purpose device such as a tablet or a smartphone, but a dedicated device specialized for controlling the lighting system. Details of the controller 525 will be described in detail in the fourth embodiment.

  If a plurality of control devices are prepared as in the lighting system 500, for example, the lighting device can be controlled from different places or from a plurality of users. For example, in order to control the lighting device 103, as indicated by a white arrow, control data Dc1 for controlling the lighting device 103 generated by the tablet 121 may be transmitted to the lighting device 103, or a solid arrow may be used. As shown, control data Dc2 (fifth data) for controlling the lighting device 103 generated by the tablet 524 (second control device) located away from the tablet 121 may be transmitted to the lighting device 103.

Next, a connection relationship between the control devices 522 to 524 in the network will be described.
Of the control devices 522 to 524, the tablets 522 and 523 are connected to the lighting device 101 by connections CN1y and CN1x using these as peripherals. The tablet 524 is connected to the lighting device 104 by a connection CN1w that uses this as a peripheral. The controller 525 is connected by a connection CN1v using this as a peripheral. In the present embodiment, as described in the first embodiment, the control device operates only as a peripheral. Therefore, as indicated by white crosses, the control devices, for example, between the tablets 121 and 522 and between the tablets 522 and 523 are not connected by a connection.

  Normally, in a system using Bluetooth, a control source device operates as a central device, and a control destination device operates as a peripheral device. In the illumination system 100 ′ according to the comparative example, as illustrated in FIG. 12, the tablet 121 as the control device operates as a central device, and the lighting fixture 101 operates as a peripheral device. However, in this case, in principle, a plurality of control devices (peripherals) cannot be connected to one lighting device (central). Therefore, when it is desired to use a plurality of control devices in the lighting system, it is necessary to connect to different lighting devices. That is, in the case of the lighting system 100 ′, it is not possible to add more control devices than the number of lighting devices. In addition, since only one control device can be connected to the same lighting device, there is a restriction on the location of the control device.

  In this regard, in the case of the lighting system 500, as described above, the control device operates as a peripheral. Therefore, a plurality of control devices can be connected to one lighting device, such as the lighting device 101 and the tablets 121, 522, and 523.

  In the case of FIG. 17, all of the control devices 121, 522 to 524, and 525 are connected to the lighting device, but the relay device, the human sensor device, and the illuminance sensor device described in the second embodiment. Can also be connected.

Similarly to the tablet 121 shown in FIG. 17, the controller 525 has a communication function based on Bluetooth, and controls the lighting device using a connection using the controller 525 as a peripheral. Since Bluetooth is omnidirectional, it is not necessary to pay attention to the direction of the controller, unlike a conventional controller using directional infrared rays.

  Further, unlike the tablet 121, the controller 525 is in a state where the lighting device can be controlled by a button operation by the user when power is supplied from a battery or the like. In this respect, unlike general-purpose devices such as tablets and smartphones that need to once launch an application, troublesomeness at the time of device activation is reduced.

Button 618: Switches the light source of the selected lighting device to red.
Button 619: Switches the light source of the selected lighting device to green.
Button 620: Switches the light source of the selected lighting device to blue.
Button 621: The light color of the light source of the selected lighting device is continuously changed by the first button operation, and the light color of the changed light source is determined by the second button operation.
Button 622: Controls the light source of the registered lighting device with the dimming and toning patterns prestored as a scene.
Button 623: Turns on / off the illumination device corresponding to the channel.
Button 624: The channel to be selected is switched every time the button is pressed.
Button 625: Selects all channels.
Further, the controller 525 may include a button 626 for assigning functions other than the above in addition to the buttons 611 to 625.

  As described above, according to the present embodiment, by preparing a dedicated controller specialized for the illumination device as shown in FIG. 18, even the user who is unfamiliar with a general-purpose device such as a tablet can perform illumination according to the above-described embodiment. The system can be easily introduced and used.

[Fifth Embodiment]
In the fifth embodiment, an illumination system using a beacon device will be described.
FIG. 19 is a diagram illustrating an outline of an illumination system according to the fifth embodiment.
The illumination system 700 is configured to include a beacon device 741 that is a terminal device with respect to the illumination system 100. This beacon device 741 has at least an advertising function. In the case of the lighting system 700, when the lighting devices 101 to 113 detect the advertising ADbc transmitted from the beacon device 741, the lighting device 1011 113 controls the light source of the lighting device 101-113 or transmits the advertising ADbc to the tablet 121 as the beacon data Db. have.

  If this illumination system 700 is used, for example, an energy saving system that turns on / off the light source of the illumination apparatus in accordance with the presence / absence of a person can be constructed. In the illumination system 700, as a control method of the illumination device, for example, the illumination device detects advertising of the beacon device and directly controls the light source possessed by the illumination device (hereinafter referred to as “direct control method”). ) And a method in which the lighting device once transmits the detected advertising as beacon data to the control device, and the control device controls the lighting device based on this (hereinafter referred to as an “indirect control method”).

  In the case of the direct control method, for example, when a person carrying the beacon device 741 is in the vicinity of the lighting device 103, the lighting device 103 detects the advertising ADbc of the beacon device 741 and turns on the light source that it has. Conversely, if the person is far away and advertising ADbc cannot be detected, the light source is turned off. Thus, the direct control method has an advantage that the response of the lighting device is fast because the light source is directly controlled without using the control device. Therefore, for example, when a person walks as shown by the hatched arrow in FIG. 19, the light sources of the lighting devices 101, 102, 103, and 104 are sequentially turned on in accordance with the walk. It can be said that this is an effective control method for a system that requires a high response speed of the lighting device to some extent. In the above example, the light source is turned on / off based on advertising of the beacon device, but the light color and brightness of the light source can also be controlled. In this case, the control content may be set in advance from the control device to the lighting device.

  On the other hand, in the case of the indirect control method, for example, as shown in FIG. 19, it is assumed that the illumination devices 102 and 103 detect the advertising ADbc by scanning SC2 and SC3, respectively. In this case, the illumination devices 102 and 103 transmit their advertising ADbc to the tablet 121 as beacon data Db1 and Db2, as indicated by black arrows and gray arrows. Then, the tablet 121 which received these takes out the radio field intensity of the advertising ADbc detected by the illumination devices 102 and 103 from the beacon data Db1 and Db2. Then, the respective values are compared to determine which of the lighting devices 102 and 103 the beacon device 741 (person) is closer to. Then, the tablet 121 transmits control data Dc for turning on the light source to the closer lighting device 103 as indicated by the white arrow. Finally, the illuminating device 103 that has received this turns on its own light source. In this way, the indirect control method is inferior to the direct control method in terms of reaction speed in order to control the lighting device via the control device, but since the control is performed based on a plurality of beacon data, the direct control method Rather, the lighting device can be controlled more precisely. In the case of the indirect control method, the control device can also capture the position of the person (beacon device) from the difference in the signal strength of the advertising ADbc detected by the plurality of lighting devices. In this case, control of various lighting devices using the position information can be realized. In the above example, the light source is turned on / off based on the beacon data, but the light color and brightness of the light source can also be controlled.

  As described above, according to the present embodiment, by introducing a beacon device and carrying the beacon device to a person, it becomes possible to grasp the presence / absence of the person and the position of the person. Lighting system can be provided.
