[0010] Hereinafter, the embodiments will be described in detail with reference to the drawings. Note that the embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, component arrangement and connection forms, steps, and order of steps shown in the following embodiments are merely examples and are not intended to limit the present invention. In addition, among the components in the following embodiments, components that are not described in the independent claims will be described as optional components.

[0011] In addition, each drawing is a schematic diagram and is not necessarily a precise illustration. In addition, in each drawing, the same reference numerals are used for substantially the same configuration, and duplicated explanations may be omitted or simplified.

[0012] (Embodiment) [composition] First, the configuration of a communication system according to an embodiment will be described. Fig. 1 is a block diagram showing a functional configuration of a communication system according to an embodiment. As shown in Fig. 1, communication system 10 includes a plurality of lighting fixtures 20 and an information terminal 30. Communication system 10 can be referred to as a lighting system.

[0013] In the communication system 10, each of the multiple lighting fixtures 20 has a wireless communication function, and the multiple lighting fixtures 20 form a wireless mesh network (hereinafter also simply referred to as a mesh network). FIG. 2 is a diagram conceptually illustrating a mesh network. Each circle in FIG. 2 corresponds to one lighting fixture 20 (in other words, a communication node). In the mesh network, when information is transmitted from one communication node (also referred to as a first communication node) to another communication node (also referred to as a second communication node), the information is transmitted, for example, by a routing method, but may also be transmitted by a flooding method.

[0014] The information transmitted through the mesh network is, for example, control information for turning on, off, or dimming the lighting fixture 20.

[0015] First, the lighting fixture 20 will be described. The lighting fixture 20 is a base light or the like that is installed on the ceiling of an indoor space and illuminates the indoor space. As described above, each of the multiple lighting fixtures 20 has a wireless communication function, and the multiple lighting fixtures 20 form a mesh network. The form of the lighting fixture 20 is not particularly limited, and may be a ceiling light, a downlight, a spotlight, or the like. Specifically, the lighting fixture 20 includes a wireless communication unit 21 and a light source 22.

[0016] The wireless communication unit 21 is a wireless communication circuit that enables the lighting fixture 20 to perform wireless communication (more specifically, radio wave communication) with other lighting fixtures 20 and with the information terminal 30. After the lighting fixture 20 joins the mesh network, the wireless communication unit 21 performs communication through the mesh network. Before the lighting fixture 20 joins the mesh network, the wireless communication unit 21 periodically transmits a beacon signal (sometimes called an advertisement signal) and performs wireless communication individually with the information terminal 30 that receives the beacon signal. Specifically, the wireless communication unit 21 performs wireless communication according to a communication standard such as BLE (Bluetooth (registered trademark) Low Energy) or Wi-Fi (registered trademark).

[0017] Light source 22 emits white light into the indoor space so that lighting device 20 can illuminate the indoor space. Light source 22 is realized by, for example, an LED (Light Emitting Diode) element, but may also be realized by other light emitting elements such as a semiconductor laser, an organic EL (Electro-Luminescence), or an inorganic EL.

[0018] Next, the configuration of the information terminal 30 will be described. The information terminal 30 is an information terminal that performs an initial setting operation for allowing a plurality of lighting fixtures 20 to join the mesh network. The information terminal 30 is, for example, a smartphone, a tablet terminal, or a mobile terminal such as a PDA (Personal Digital Assistant). The information terminal 30 may also be a dedicated remote controller used in the communication system 10. The information terminal 30 is used by a user that performs an initial setting operation. The user here is, for example, an installer who installed a plurality of lighting fixtures 20 on the ceiling, but may also be a user other than the installer. The information terminal 30 specifically includes an operation reception unit 31, a display unit 32, a wireless communication unit 33, a control unit 34, and a storage unit 35.

[0019] The operation reception unit 31 receives operations from a user. Specifically, the operation reception unit 31 is realized by a touch panel or the like.

[0020] The display unit 32 displays images necessary for the above-mentioned initial setting work. The display unit 32 is realized by a display panel such as a liquid crystal panel or an organic EL panel.

[0021] The wireless communication unit 33 is a wireless communication circuit that enables the information terminal 30 to perform wireless communication (more specifically, radio wave communication) with each of the multiple lighting fixtures 20. Specifically, the wireless communication unit 33 performs wireless communication in accordance with a communication standard such as BLE or Wi-Fi (registered trademark).

[0022] The control unit 34 processes information about the initial setting operation in response to the user's operation accepted by the operation acceptance unit 31. The control unit 34 is realized by, for example, a microcomputer, but may also be realized by a processor or a dedicated circuit. The functions of the control unit 34 are realized by hardware such as a microcomputer or a processor constituting the control unit 34 executing a computer program (software) stored in the storage unit 35.

[0023] The storage unit 35 is a storage device that stores information necessary for information processing related to the initial setting operation of the computer program or the like executed by the control unit 34. The storage unit 35 is realized by, for example, a semiconductor memory.

[0024] [Initial setting operation] Next, an initial setting operation for constructing a mesh network will be described. Fig. 3 is a sequence diagram of the initial setting operation. The initial setting operation shown in Fig. 3 is performed, for example, after an installer installs a plurality of lighting fixtures 20 on a ceiling.

[0025] In the initial setting operation, control unit 34 of information terminal 30 performs a registration process (S11 to S16) for lighting device 20. First, control unit 34 displays a registration screen for lighting device 20 on display unit 32 based on a user's operation or the like (S11). FIG. 4 shows an example of the registration screen for lighting device 20. While the registration screen of FIG. 4 is displayed, operation acceptance unit 31 of information terminal 30 accepts an operation on registration icon 32a from the user (S12).

[0026] Here, each of the lighting fixtures 20 periodically transmits a beacon signal (also called an advertisement signal) before joining the mesh network (S13). When an operation on the registration icon 32a is accepted in step S12, the wireless communication unit 33 of the information terminal 30 receives the beacon signal. The beacon signal emitted by each of the lighting fixtures 20 includes identification information and type information of the lighting fixture 20.

[0027] The identification information is, for example, a Media Access Control (MAC) address, but is not limited to a MAC address as long as it can uniquely identify lighting fixture 20. The type information is information indicating which type lighting fixture 20 belongs to, such as a lighting fixture with a dimming function (also referred to as a dimming fixture), a lighting fixture with a projector function (also referred to as a projector fixture), or a color lighting fixture (also referred to as a color fixture). Note that a color lighting fixture is a lighting fixture that includes a light source that emits red light, a light source that emits green light, and a light source that emits blue light, and can achieve a variety of emitted colors by mixing the red light, the green light, and the blue light.

[0028] The control unit 34 determines a group of the lighting devices 20 based on the type information included in the received beacon signal (S14), and stores (registers) the identification information included in the received beacon signal in association with the determined group in the storage unit 35 (S15). That is, the control unit 34 automatically groups the lighting devices 20 that are the transmission sources of the beacon signals received in step S13 according to the types of the lighting devices 20. The control unit 34 also displays the grouping results on a registration screen (S16). Fig. 5 is a diagram showing an example of the registration screen on which the grouping results are displayed.

[0029] 5 shows the grouping results when beacon signals are received from 19 lighting fixtures 20 in step S13 and the 19 lighting fixtures 20 include 12 dimmer fixtures, 6 projector fixtures, and 1 color fixture. The control unit 34 assigns the 12 dimmer fixtures to zone 1 (corresponding to a group), the 6 projector fixtures to zone 2, and the 1 color fixture to zone 3.

[0030] A list of identification information of the lighting fixtures 20 belonging to each group is displayed on the right side of the registration screen in Fig. 5. In the example of Fig. 5, since zone 1 is selected, the identification information (L001 to L012) of the lighting fixtures 20 (12 dimmers) belonging to zone 1 are displayed on the right side of the registration screen.

[0031] In addition, a change icon 32b is provided in the upper right portion of the registration screen. The user can manually change the group to which lighting device 20 belongs, which was automatically determined, by operating change icon 32b.

[0032] After the lighting fixture 20 has been registered as described above, the control unit 34 performs a setting process for having the lighting fixture 20 join the mesh network (S17 to S18). For example, the control unit 34 starts individual wireless communication with the lighting fixture 20 specified by the user using the identification information of the lighting fixture 20 (the identification information registered in step S15), and causes the wireless communication unit 33 to transmit setting information to the lighting fixture 20 (S17). The lighting fixture 20 receives the setting information and stores it in a storage unit (not shown) provided in the lighting fixture 20 (S18).

[0033] The setting information is information for the lighting fixture 20 to join the mesh network. The setting information includes the network ID of the mesh network to which the lighting fixture 20 belongs, and address information (unicast address) of the lighting fixture 20 used for communication within the mesh network. The setting information may also include a security passcode used for communication within the mesh network, information on the information terminal 30 (information on a device that manages the mesh network), etc., as necessary. The lighting fixture 20 with the setting information stored in the storage unit can join the mesh network.

[0034] The process of step S17 and the process of step S18 are repeated, for example, for the number of lighting devices 20 desired to join the mesh network. The lighting device 20 that has joined the mesh network stops, for example, the periodic transmission of a beacon signal that was being performed before the joining.

[0035] As described above, the information terminal 30 includes a wireless communication unit 33 that receives a beacon signal emitted by the lighting device 20, and a control unit 34 that determines a group for the lighting device 20 based on type information of the lighting device 20 included in the received beacon signal. The control unit 34 registers the identification information of the lighting device 20 included in the received beacon signal in association with the determined group. The control unit 34 also wirelessly communicates with the lighting device 20 based on the registered identification information, thereby allowing the lighting device 20 to join the mesh network.

[0036] In this way, if the group of lighting device 20 is automatically determined when lighting device 20 is registered, it is possible to omit an operation by the user to determine the group of lighting device 20. In other words, user convenience is improved.

[0037] The group is used when a user uses information terminal 30 to control multiple lighting devices 20 in group units. Control unit 34 of information terminal 30 can cause one or more lighting devices 20 belonging to the same group to play the same scene. In other words, control unit 34 can cause one or more lighting devices 20 belonging to the same group to perform the same operation. A scene is defined by at least one lighting parameter, such as the dimming ratio and color temperature, to be instructed to lighting devices 20.

[0038] Furthermore, when controlling multiple lighting devices 20 to operate according to a predetermined schedule, controller 34 can set a schedule for each group. That is, controller 34 can control one or more lighting devices 20 belonging to the same group to operate according to the same schedule.

[0039] As described above, if a group is determined for each model of lighting fixture 20, lighting fixtures 20 belonging to the same group can perform the same operation. For example, lighting fixtures 20 that support the color light-emitting function belong to a group of color fixtures, and lighting fixtures 20 that do not support the color light-emitting function do not belong to the group of color fixtures. Therefore, errors are unlikely to occur even if an operation related to the color light-emitting function is instructed to a group of color fixtures. For this reason, a configuration in which a group is determined for each model of lighting fixture 20 is particularly useful when lighting fixtures 20 belonging to a determined group are to perform the same operation.

[0040] [Grouping Variation 1] In the above embodiment, the grouping is performed based on the type information included in the beacon signal. However, when the beacon signal includes other information, the grouping may be performed based on the other information.

[0041] For example, if the beacon signal includes installation location information (in other words, coordinate information) of the lighting device 20, the control unit 34 of the information terminal 30 may determine that lighting devices 20 that are installed in close locations are placed in the same group, based on the installation location information.

[0042] Furthermore, if the beacon signal includes area identification information of the area in which the lighting fixtures 20 are installed, the control unit 34 of the information terminal 30 may determine that the lighting fixtures 20 installed in the same area belong to the same group based on the area identification information. Note that an area is a unit into which a space in a facility is divided and in which multiple lighting fixtures 20 are installed, and specifically includes an office area, a conference room, a rest area, etc.

[0043] [Grouping Variation 2] However, when the indoor space in which the multiple lighting fixtures 20 are installed is large, the information terminal 30 cannot receive beacon signals from all of the multiple lighting fixtures 20. Therefore, the user registers the multiple lighting fixtures 20 in multiple batches. In such a case, the control unit 34 of the information terminal 30 may determine that the lighting fixtures 20 registered together (substantially simultaneously) belong to the same group. FIG. 6 is a diagram for explaining an example of determining that the lighting fixtures 20 registered together belong to the same group. Note that FIG. 6 is a top view showing an indoor space in which the multiple lighting fixtures 20 are installed, and each circle in FIG. 6 corresponds to one lighting fixture 20.

[0044] As shown in Fig. 6(a), when a user carrying information terminal 30 operates registration icon 32a at a certain location, wireless communication unit 33 of information terminal 30 can receive beacon signals from eight lighting fixtures 20 surrounded by dashed lines that are located near information terminal 30 within a certain period of time after registration icon 32a is operated. That is, control unit 34 of information terminal 30 can register the eight lighting fixtures 20 surrounded by dashed lines in Fig. 6(a). Control unit 34 then determines that these eight fixtures belong to the same group (group 1).

[0045] Next, as shown in Fig. 6(b), the user moves to a different location and operates registration icon 32a. In this case, wireless communication unit 33 of information terminal 30 can receive beacon signals from eight lighting fixtures 20 surrounded by dashed lines that are located near information terminal 30 during a certain period after registration icon 32a is operated. That is, control unit 34 of information terminal 30 can register the eight lighting fixtures 20 surrounded by dashed lines in Fig. 6(b). Control unit 34 then determines that these eight lighting fixtures belong to the same group (group 2).

[0046] In this way, wireless communication unit 33 of information terminal 30 may receive multiple beacon signals over a certain period of time, and control unit 34 may determine that multiple lighting devices 20 that are the source of the multiple beacon signals belong to the same group. This type of grouping allows information terminal 30 to cause nearby lighting devices 20 to belong to the same group.

[0047] [Modification of registration process] When map information (such as a lighting distribution diagram) showing the arrangement (installation locations) of multiple lighting fixtures 20 exists and the map information is pre-stored in the memory unit 35 of the information terminal 30, in the registration process, the control unit 34 registers the identification information of the lighting fixtures 20 in association with the installation location information of the lighting fixtures 20.

[0048] For example, the control unit 34 blinks each of the lighting fixtures 20 one by one by wirelessly communicating with each of the lighting fixtures 20 individually based on the identification information included in the beacon signal received in step S13. The user inputs to the information terminal 30 (operation receiving unit 31) which lighting fixture shown in the map information (lighting fixture in the drawing) the blinking lighting fixture 20 corresponds to. This enables the control unit 34 to register the identification information of the lighting fixture 20 in association with the installation location information of the lighting fixture 20.

[0049] In this way, when map information is stored in advance in memory unit 35, it is possible to group multiple lighting fixtures 20 based on the map information, and it is also possible to omit the group determination process (automatic grouping) in step S14.

[0050] Therefore, the control unit 34 of the information terminal 30 may determine whether or not there is map information (for example, whether or not the map information is stored in the memory unit 35), and if it is determined that there is map information, it may omit the grouping process of step S14, and if it is determined that there is no map information, it may perform the grouping process of step S14.

[0051] This allows the information terminal 30 to group a plurality of lighting fixtures 20 as necessary.

[0052] [Other variations] In the above embodiment, a plurality of lighting fixtures 20 are grouped, but a plurality of other devices other than lighting fixtures 20 may be grouped, or a plurality of devices that are a mixture of lighting fixtures 20 and other devices may be grouped. Note that the other devices in this case are devices that have wireless communication capabilities (devices that can emit beacon signals).

[0053] Examples of the other devices include an alternating current (AC) relay, a pulse width modulation (PWM) dimmer, and a scheduler. The AC relay is, for example, a device that can turn on and off a lighting fixture attached to the AC relay by turning on and off the supply of AC power to the lighting fixture. The AC relay is a device that is connected to a wiring duct, and may be a device that can turn on and off all lighting fixtures attached to the wiring duct by turning on and off the supply of AC power to the wiring duct. The PWM dimmer is a device that can dim the lighting fixture attached to the PWM dimmer. The scheduler is a device that turns on, off, or dims a plurality of lighting fixtures 20 according to a preset schedule.

[0054] The other devices may be devices that are not directly related to lighting, such as an air conditioner, a ventilator, a camera, a motion sensor, or an environmental sensor. The environmental sensor may include a temperature sensor, a humidity sensor, a carbon dioxide concentration sensor, and a PM (Particle Matter) sensor.

[0055] It is not essential that the plurality of devices to be grouped, such as the plurality of lighting fixtures 20 or the other devices described above, form a mesh network. The plurality of devices to be grouped may form a wireless communication network other than a mesh network.
