Fig. 1 is a block diagram showing a functional configuration of an illumination system of an embodiment. In fig. 1, two lighting systems, a first lighting system 10a and a second lighting system 10b, are illustrated. The configuration of the first illumination system 10a will be described below, and the configuration of the second illumination system 10b is the same as that of the first illumination system 10a, and therefore, the description thereof will be omitted.

The first lighting fixture 20a is a base lamp or the like provided in a ceiling of an indoor space and illuminating the indoor space. The form of the first lighting fixture 20a is not particularly limited, and may be a ceiling lamp, a down lamp, a spotlight, or the like.

Specifically, the wireless communication unit 21a performs wireless communication according to a communication standard such as BLE (Bluetooth (registered trademark) Low Energy) or Wi-Fi (registered trademark).

The light source 22a irradiates white light to the indoor space for the first lighting fixture 20a to illuminate the indoor space. The light source 22a is implemented by, for example, an LED (LIGHT EMITTING Diode) element, but may be implemented by another light-emitting element such as a semiconductor laser, an organic EL (electroluminescence), or an inorganic EL.

[ Problem in setting registration of Lighting fixtures ]

The first lighting system 10a is a system configured by causing the plurality of first lighting fixtures 20a to perform wireless communication with the first control terminal 30a, respectively, and thereby registering the plurality of first lighting fixtures 20a in the first control terminal 30 a. As a result of the setting registration, the first user of the first lighting system 10a can perform light emission control on the plurality of first lighting fixtures 20a by operating the first control terminal 30 a.

Specifically, by the above setting registration, the network IDs of the first wireless communication networks to which the first control terminal 30a and the plurality of first lighting fixtures 20a are attached, address information (unicast addresses) of the plurality of first lighting fixtures 20a, and the like are stored in the storage unit 35a of the first control terminal 30 a. Further, the storage unit 24a of the first lighting fixture 20a stores a network ID of the first wireless communication network, address information of the first control terminal 30a, address information of the other first lighting fixtures 20a, and the like. The first control terminal 30a and the plurality of first lighting fixtures 20a may be said to be nodes belonging to a first wireless communication network. The first wireless communication network is, for example, a wireless mesh network.

The second lighting system 10b is a system configured by causing the plurality of second lighting fixtures 20b to perform wireless communication with the second control terminal 30b, respectively, and thereby registering the plurality of second lighting fixtures 20b in the second control terminal 30 b. As a result of the setting registration, the second user of the second lighting system 10b can perform light emission control on the plurality of second lighting fixtures 20b by operating the second control terminal 30 b.

Specifically, by the above setting registration, the network IDs of the second wireless communication networks to which the second control terminal 30b and the plurality of second lighting fixtures 20b are attached, address information of the plurality of second lighting fixtures 20b, and the like are stored in the storage unit 35b of the second control terminal 30 b. In the storage unit 24b of the second lighting fixture 20b, a network ID of the second wireless communication network, address information of the second control terminal 30b, address information of the other second lighting fixtures 20b, and the like are stored. The second control terminal 30b and the plurality of second lighting fixtures 20b may be said to be nodes belonging to a second wireless communication network.

Here, in the setting registration, a lighting fixture that should be set to be registered as the second lighting fixture 20b may be set to be registered as the first lighting fixture 20a. Fig. 2 is a diagram for explaining an example in which erroneous setting registration is performed, and fig. 2 is a diagram showing a planar arrangement of the lighting fixtures indicated by circles.

As shown in fig. 2 (a), 12 lighting fixtures are provided in each of the first space 40a (for example, a space in the floor of the store a) and the second space 40B (for example, a space in the floor of the store B adjacent to the store a).

Here, when the first control terminal 30a is used to register 12 lighting fixture settings provided in the first space 40a as the first lighting fixture 20a, a signal wirelessly transmitted by the first control terminal 30a may be transmitted to a lighting fixture provided in the second space 40b or a signal wirelessly transmitted by a lighting fixture provided in the second space 40b may be transmitted to the first control terminal 30 a. Then, as shown in fig. 2 (b), there is a possibility that one of the lighting fixtures provided in the second space 40b is erroneously set and registered as the first lighting fixture 20a. In fig. 2 (b), a hatched circle indicates the first lighting fixture 20a, a rectangular thick frame surrounds the first lighting fixture, and a hatched circle indicates a lighting fixture that is erroneously set to be registered.

Next, when the second control terminal 30b is used to register the 12 lighting fixture settings provided in the second space 40b as the second lighting fixture 20b, even if the signal wirelessly transmitted by the second control terminal 30b is transmitted to 1 lighting fixture already registered as the first lighting fixture 20a, no subsequent processing (reception processing of the signal, etc.) is performed. That is, the first lighting fixture 20a cannot communicate with a node subordinate to the wireless communication network other than the first wireless communication network. Therefore, as shown in fig. 2 (c), 1 lighting fixture that should be set to be registered as the second lighting fixture 20b remains set to be registered as the first lighting fixture 20 a.

When the first space 40a is a space in the use area of the store a and the second space 40B is a space in the use area of the store B adjacent to the store a, the first user who becomes the store a can control the first lighting fixture 20a in the use area of the store B by operating the first control terminal 30 a. However, in general, after the setting registration, the first lighting fixture 20a does not react to the signal wirelessly transmitted by the second control terminal 30 b. Accordingly, there is room for research on a method of canceling setting registration of the first lighting fixture 20a that is erroneously set and registered using the second control terminal 30 b.

As a method for canceling the setting registration of the lighting apparatus without using the second control terminal 30b, for example, a method in which a dedicated button for canceling is provided in the lighting apparatus and the setting registration is canceled by pressing the button is considered. As a disadvantage of this method, there can be exemplified: the cost of the lighting fixture is increased, and it is difficult for the operator to press the dedicated button because the lighting fixture is disposed at a high place. In addition, the provision of a dedicated button in the lighting apparatus is itself difficult in terms of structure, which is also a technical problem.

Further, a method of canceling the setting registration by causing the lighting fixture to communicate with a dedicated terminal (for example, an infrared remote controller) other than the control terminal is also considered. As a disadvantage of this method, there can be exemplified: it is necessary to provide a communication function (for example, an infrared communication module) with a dedicated terminal in the lighting fixture, which increases the cost of the lighting fixture.

[ Example 1 of setting Release method ]

Hereinafter, example 1 of a method of canceling the setting registration of the first lighting fixture 20a (hereinafter, also referred to as a setting canceling method) using the second control terminal 30b will be described. Fig. 3 is a timing chart of example 1 of the setting canceling method.

By operating the second control terminal 30b, the operator performs a test for attempting to illuminate a plurality of lighting fixtures or the like actually provided in the second space 40 b. By this test, the operator visually confirms in advance the installation position of the first lighting fixture 20a (the lighting fixture to be the subject of the release of the setting) which is the lighting fixture that cannot be controlled by the operation of the second control terminal 30b, that is, the second space 40 b.

Next, the operator performs a predetermined operation on the wall switch 50, and the wall switch 50 receives the predetermined operation (S11). The wall switch 50 is a device capable of turning on and off the supply of ac power to a plurality of lighting fixtures (1 first lighting fixture 20a and 11 second lighting fixtures 20b in the example of fig. 2) provided in the second space 40b in a unified manner, and is provided on the wall of the second space 40b.

The predetermined operation is an operation for turning on and off power supply to the plurality of lighting fixtures in a predetermined mode. The predetermined pattern is, for example, a pattern in which the opening and closing are continuously repeated 3 times at intervals of 0.5 seconds or less. The predetermined mode is, for example, a mode that does not occur (does not occur if not intentionally performed) during the normal operation of the wall switch 50. The specific mode is not particularly limited as long as the power supply is turned on and off in a predetermined mode by a combination of the number of times of turning on and off the power supply and the time interval of turning on and off the power supply.

The control unit (control unit 23a or control unit 23 b) of each of the plurality of lighting fixtures (specifically, 1 first lighting fixture 20a and 11 second lighting fixtures 20 b) provided in the second space 40b detects on and off of power supply in a predetermined mode corresponding to a predetermined operation (S12), and transitions to the release mode when the detection is triggered (S13). In contrast to the first lighting fixture 20a which is not in the released mode, which does not perform the reception processing but discards the wireless signal (information) from the second wireless communication network (second control terminal), the first lighting fixture 20a which is in the released mode performs the reception processing when receiving the wireless signal (information) from the second wireless communication network. That is, the first lighting fixture 20a that has transitioned to the release mode receives information from a wireless communication network (second wireless communication network) to which the first lighting fixture 20a does not belong as a processing target. The same applies to the second lighting fixture 20b shifted to the release mode.

In this way, the first lighting fixture 20a is shifted to the release mode, whereby the first lighting fixture 20a and the second control terminal 30b become capable of communication. The plurality of lighting fixtures automatically return to the normal mode from the release mode after a predetermined period of time has elapsed, but may return to the normal mode from the release mode after a determination process or a release process described later. That is, the plurality of lighting fixtures transition to the release mode only during a defined period.

The control unit (control unit 23a or control unit 23 b) of each of the plurality of lighting fixtures provided in the second space 40b causes the light source (light source 22a or light source 22 b) to emit light in different light emission modes with the detection in step S12 as a trigger (S14). The light emission pattern is, for example, a light emission pattern in which the light source blinks. The control unit of each of the plurality of lighting fixtures randomly determines the number of times of lighting during blinking, the time interval of lighting during blinking, and the emission color at the time of lighting, for example, using a random number, and causes the light source to emit light in the determined number of times of lighting, the time interval of lighting, and the emission color (i.e., the determined emission pattern). As a result, the plurality of lighting fixtures emit light in mutually different light emission modes.

The light emission pattern may be a light emission pattern in which the light source is turned on only once and the lighting time is changed randomly. The light emission pattern may be determined based on at least 1 of the lighting time, the number of lighting times, the lighting time interval, the light emission color, and the like. Although not shown, the control unit of each of the plurality of lighting apparatuses stores information indicating the light emission pattern in which the light is emitted in advance in the storage unit (the storage unit 24a or the storage unit 24 b).

The operator visually confirms in which lighting mode the first lighting fixture 20a of the plurality of lighting fixtures that emit light in the different lighting modes emits light, and performs the setting canceling operation on the second control terminal 30b, and the operation receiving unit 31b receives the setting canceling operation (S15). The setting release operation includes an operation of designating a visually recognized light emission mode, and when the setting release operation is performed, a display screen such as that shown in fig. 4 is displayed on the display unit 32 b. Fig. 4 is a diagram showing an example of a display screen for specifying a light emission mode.

When the setting release operation is completed, the information processing section 34b broadcasts a release request to the plurality of lighting fixtures using the wireless communication section 33b (S16). The information processing unit 34b converts the information indicating the light emission pattern specified in step S15 and the public key into a hash value (hereinafter also referred to as a second hash value) using a hash function, and includes the second hash value in the release request. That is, the release request includes the second hash value indicating the light emission pattern specified in step S15. The common secret code and the hash function are stored in the storage unit 35b in advance. In addition, in the release request, a (arbitrary) wireless communication network other than the second wireless communication network is designated as the destination. In other words, the information processing unit 34b designates the lighting apparatuses other than the second lighting apparatus 20b as the receiving parties and broadcasts the release request.

Each of the plurality of lighting fixtures receives the release request. Here, in the release request, the wireless communication network other than the second wireless communication network is designated as the destination, and thus the received release request is discarded from the plurality of second lighting fixtures 20b belonging to the second wireless communication network, and no subsequent processing is performed.

On the other hand, the wireless communication unit 21a of the first lighting fixture 20a receives the release request, and the control unit 23a performs the determination process and the release process (S17). In the determination process, the control unit 23a converts the information showing the light emission pattern of the light source 22a in step S14, that is, the information stored in the storage unit 24a in step S14 and the common secret code, into a hash value (hereinafter also referred to as a first hash value) using a hash function. The common secret code and the hash function are stored in the storage unit 24a in advance, as in the storage unit 35b of the second control terminal 30 b. The control unit 23a determines whether or not the second hash value included in the received release request matches the first hash value. That is, the control unit 23a determines whether or not the light emission pattern shown by the second hash value (hereinafter also referred to as the second light emission pattern) matches the light emission pattern of the light source 22a in step S14 (hereinafter also referred to as the first light emission pattern).

When determining that the second light emission pattern indicated by the second hash value matches the first light emission pattern of the light source 22a in step S14, the control unit 23a performs the cancellation process. In the release process, the control unit 23a deletes the information such as the network ID of the first wireless communication network stored in the storage unit 24b, and disconnects from the first wireless communication network. That is, the setting registration of the first lighting fixture 20a is released, and the first lighting fixture 20a is restored to a lighting fixture not belonging to the wireless communication network (a lighting fixture not set to be registered). A lighting fixture not belonging to the wireless communication network can be said to be a lighting fixture capable of setting registration (joining) to the second wireless communication network.

In the determination processing in step S17, when it is determined that the second light emission pattern indicated by the second hash value does not match the first light emission pattern of the light source 22a in step S14, the release processing is not performed.

When the release process is completed, the control unit 23a transmits a release notification indicating that the release process is completed to the second control terminal 30b using the wireless communication unit 21a (S18).

The wireless communication unit 33b of the second control terminal 30b receives the release notification, and the information processing unit 34b displays a notification screen on the display unit 32b based on the received release notification (S19). The notification screen is a display screen for notifying that the setting registration of the first lighting fixture 20a is released.

If there are a plurality of first lighting fixtures 20a to be released from setting registration, the processing of steps S11 to S19 may be performed again.

Thus, example 1 of the setting release method includes: step S11 of receiving a prescribed operation by the wall switch 50 which turns on and off the power supply to a plurality of lighting fixtures including the first lighting fixture 20a belonging to the first wireless communication network; step S14, detecting that a plurality of lighting fixtures which are powered on and off in a prescribed mode corresponding to a prescribed operation emit light according to mutually different light-emitting modes; step S15 and step S16, the second control terminal 30b belonging to a second wireless communication network different from the first wireless communication network receives a designation of a light emission mode from the user, and wirelessly transmits a release request (an example of the first information) showing the designated light emission mode, that is, the second light emission mode, to the plurality of lighting fixtures; in step S17, when it is determined that the second light emission pattern indicated by the release request matches the first light emission pattern, which is the light emission pattern of the light source 22a in step S14, the first lighting fixture 20a performs a process of disconnecting from the first wireless communication network.

According to example 1 of the setting canceling method, the operator can cancel the setting registration of the first lighting fixture 20a using the wall switch 50 and the second control terminal 30 b. According to example 1 of the setting canceling method, the setting registration of the first lighting fixture 20a can be canceled by using the conventional wireless communication functions of the second control terminal 30b, the first lighting fixture 20a, and the second lighting fixture 20b, and the increase in the cost of hardware of the first lighting fixture 20a and the second lighting fixture 20b can be suppressed. Since the light emission pattern in step S14 is randomly determined, example 1 of the setting release method can be said to be a method having high resistance to replay attack and the like and high security.

In the release request broadcast in step S16, the wireless communication network other than the second wireless communication network is designated as the destination, but the release request may be broadcast only without designating the specific wireless communication network as the destination. In this case, not only the first lighting fixture 20a but also the plurality of second lighting fixtures 20b perform the determination process, but if the light emission mode designated by the operator in step S15 is the light emission mode of the first lighting fixture 20a, the plurality of second lighting fixtures 20b fail in the determination process and do not perform the release process.

However, by designating the wireless communication network other than the second wireless communication network as the destination in advance, when the worker erroneously designates the light emission mode of the second lighting fixture 20b in step S15, the effect of suppressing the second lighting fixture 20b from performing the release process (the setting registration of the second lighting fixture 20b is released) can be obtained.

In example 1 of the setting canceling method, the security is improved by converting the information showing the light emission pattern designated by the operator into the hash value, but the security may be improved by performing the encryption processing on the information showing the light emission pattern. In addition, the information showing the light emission pattern may be directly used as it is.

[ Example 2 of setting Release method ]

In example 1 of the setting canceling method, the plurality of lighting apparatuses to which power is supplied are turned on and off in a lump by the wall switch 50 to emit light in mutually different light emission modes, but when the number of the plurality of lighting apparatuses is large, the possibility of the operator looking at the light emission mode is increased. Therefore, example 2 of a setting canceling method of a lighting fixture capable of locking light emission in advance will be described. Fig. 5 is a timing chart of example 2 of the setting canceling method. In addition, in the following example 2 of the setting canceling method, a detailed description of the matters described in the example 1 of the setting canceling method is omitted.

The operator operates the second control terminal 30b to perform a test of attempting to illuminate a plurality of lighting fixtures actually provided in the second space 40b, and the like, and confirms in advance the installation position of the lighting fixtures that cannot be light-emission-controlled by the operation of the second control terminal 30b, that is, the first lighting fixture 20a (the lighting fixture to be the subject of the release of the setting) provided in the second space 40b by visual inspection.

Next, the operator performs a predetermined operation on the wall switch 50, and the wall switch 50 receives the predetermined operation (S21). In example 2 of the setting canceling method, the wall switch 50 is a device capable of turning on and off ac power to a plurality of lighting fixtures (12 first lighting fixtures 20a in the example of fig. 2) provided in the first space 40a and to a plurality of lighting fixtures (1 first lighting fixture 20a and 11 second lighting fixtures 20b in the example of fig. 2) provided in the second space 40b in a unified manner. The predetermined operation is as described in example 1 of the setting canceling method, and a detailed description thereof is omitted.

The control unit (control unit 23a or control unit 23 b) of each of the plurality of lighting fixtures (specifically, the plurality of first lighting fixtures 20a and the plurality of second lighting fixtures 20 b) detects on and off of power supply in a predetermined mode corresponding to a predetermined operation (S22), and transitions to a release mode (S23) upon the detection as a trigger. As described in example 1 of the setting canceling method, the canceling mode will not be described in detail.

The operator performs a lighting instruction operation on the second control terminal 30b, and the operation receiving unit 31b receives the lighting instruction operation (S24). When the information processing unit 34b receives the light emission instruction operation, it uses the wireless communication unit 33b to broadcast a light emission request to the plurality of lighting apparatuses (S25). The light emission request is information for causing only the plurality of first lighting fixtures 20a among the plurality of first lighting fixtures 20a and the plurality of second lighting fixtures 20b to emit light in mutually different light emission modes. In the request to emit light, a (arbitrary) wireless communication network other than the second wireless communication network is designated as the destination. In other words, the information processing unit 34b designates a lighting fixture other than the second lighting fixture 20b as a destination and broadcasts a light emission request.

Each of the plurality of lighting fixtures receives a request for light emission. Here, in the light emission request, the wireless communication network other than the second wireless communication network is designated as the destination, and therefore the received light emission request is discarded from the plurality of second lighting fixtures 20b belonging to the second wireless communication network, and no light is emitted.

On the other hand, the wireless communication unit 21a of each of the plurality of first lighting fixtures 20a receives the light emission request, and the control unit 23a of each of the plurality of first lighting fixtures 20a causes the light source 22a to emit light in mutually different light emission modes (S26). The control unit 23a of each of the plurality of first lighting fixtures 20a stores information indicating the light emission pattern in which the light is emitted in advance in the storage unit 24a.

The operator visually confirms in which lighting mode the first lighting fixture 20a to be released from the setting registration among the plurality of first lighting fixtures 20a that emit light in the lighting modes different from each other emits light, and performs the setting release operation on the second control terminal 30 b. The operation receiving unit 31b receives a setting release operation (S27). The setting release operation includes an operation of designating a visually recognized light emission mode, and when the setting release operation is performed, a display screen such as that shown in fig. 4 is displayed on the display unit 32 b.

When the setting release operation is completed, the information processing section 34b broadcasts a release request to the plurality of lighting fixtures using the wireless communication section 33b (S28). The information processing unit 34b converts the information indicating the light emission pattern designated in step S27 and the public key into a hash value (hereinafter also referred to as a second hash value) using a hash function, and includes the second hash value in the release request. That is, the release request includes the second hash value indicating the light emission pattern specified in step S27. In addition, in the release request, a (arbitrary) wireless communication network other than the second wireless communication network is designated as the destination. In other words, the information processing unit 34b designates the lighting apparatuses other than the second lighting apparatus 20b as the receiving parties and broadcasts the release request.

On the other hand, the wireless communication unit 21a of each of the plurality of first lighting fixtures 20a receives the release request. The control unit 23a of each of the plurality of first lighting fixtures 20a for which the setting registration is not required to be canceled performs the determination process (S29), but the second hash value included in the received cancellation request does not match the first hash value indicating the light emission pattern of the light source 22a in step S26, and thus the cancellation process is not performed.

The control unit 23a of the first lighting fixture 20a to be released from the setting registration performs the determination process, and performs the release process because the second hash value included in the received release request matches the first hash value (S30).

When the release process is completed, the control unit 23a transmits a release notification indicating that the release process is completed to the second control terminal 30b using the wireless communication unit 21a (S31).

The wireless communication unit 33b of the second control terminal 30b receives the release notification, and the information processing unit 34b displays a notification screen on the display unit 32b based on the received release notification (S32). The notification screen is a display screen for notifying that the setting registration of the first lighting fixture 20a is released.

If there are a plurality of first lighting fixtures 20a to be released from setting registration, the processing of steps S21 to S32 may be performed again.

In this way, example 2 of the setting canceling method includes step S25 of wirelessly transmitting a light emission request (an example of the second information) to the plurality of first lighting fixtures 20a and the plurality of second lighting fixtures 20b by the second control terminal 30b after step S21 and before step S26. In step S26, the light emission request is information for causing only the plurality of first lighting fixtures 20a out of the plurality of first lighting fixtures 20a and the plurality of second lighting fixtures 20b to emit light.

In example 2 of such a setting canceling method, the lighting fixture that emits light in step S26 can be locked to the first lighting fixture 20a, and thus the operator can be restrained from looking wrong in the light emission mode.

In example 2 of the setting canceling method, the wall switch 50 is configured to turn on and off the power supply to the plurality of lighting fixtures provided in the first space 40a and the plurality of lighting fixtures provided in the second space 40b. Here, as in example 1 of the setting canceling method, when the wall switch 50 is turned on/off only for the supply of electric power to the plurality of lighting fixtures provided in the second space 40b, the lighting fixtures that emit light in step S26 are only 1 first lighting fixture 20a, and the possibility of the operator looking at the wrong lighting mode becomes quite low.

Modification 1: authentication of worker ]

The authentication of the operator may be performed before step S15 and before step S24. For example, the operator performs an input operation of account information (user ID, password, etc.), and the operation receiving unit 31b of the second control terminal 30b receives the input operation, and the information processing unit 34b of the second control terminal 30b performs an authentication process of determining whether the input account information is correct (matches the account information registered in advance). The information processing unit 34b accepts the setting release operation (or the light emission instruction operation) only when the authentication process is successful (the account information is correct), and does not accept the setting release operation (or the light emission instruction operation) when the authentication process is failed (the account information is wrong). Accordingly, only the operator who has grasped the limitation of the account information is allowed to perform the setting release operation (or the light emission instruction operation), and thus the safety is improved.

In this case, the server apparatus can perform the authentication process by transmitting account information from the second control terminal 30b to the server apparatus.

Modification 2: determining the order of the subsequent processes

In step S14 of example 1 of the setting canceling method, each of the plurality of lighting fixtures randomly determines the light emission pattern based on the random number every time the on and off of the power supply in the predetermined pattern is detected. Therefore, it is also possible that 2 or more lighting fixtures emit light in the same light emission pattern. In this case, there is a possibility that the setting registration of the lighting fixtures including 2 or more lighting fixtures for which the setting registration should not be released is released.

In example 1 of the setting canceling method, the order of the processing after the determination processing may be modified as shown in fig. 6. Fig. 6 is a timing chart of a setting canceling method of the modification.

The descriptions of step S11 to step S16 have been already omitted. When the setting release operation is completed, the information processing section 34b of the second control terminal 30b broadcasts a release request to the plurality of lighting fixtures using the wireless communication section 33b (S16). The information processing unit 34b converts the information indicating the light emission pattern specified in step S15 and the public key into a hash value (hereinafter also referred to as a second hash value) using a hash function, and includes the second hash value in the release request. That is, the release request includes the second hash value indicating the light emission pattern specified in step S15. In addition, in the release request, a (arbitrary) wireless communication network other than the second wireless communication network is designated as the destination. In other words, the information processing unit 34b designates the lighting apparatuses other than the second lighting apparatus 20b as the receiving parties and broadcasts the release request.

On the other hand, the wireless communication unit 21a of the first lighting fixture 20a receives the release request, and the control unit 23a performs the determination process (S37). In the determination process, the control unit 23a determines whether or not the second hash value included in the received release request matches the first hash value.

When determining that the second hash value matches the first hash value, the control unit 23a transmits an approval request to the second control terminal 30b using the wireless communication unit 21a (S38).

The wireless communication unit 33b of the second control terminal 30b receives the approval request, and the information processing unit 34b stands by for a certain period after receiving the approval request. The length of the certain period is determined empirically or experimentally by the designer or the like of the second illumination system 10 b. The information processing unit 34b determines whether or not another approval request transmitted from another lighting apparatus is received within the certain period. When the information processing unit 34b determines that no other approval request is received (S39), it transmits approval information to the first lighting fixture 20a using the wireless communication unit 33b (S40).

The wireless communication unit 21a of the first lighting fixture 20a receives the approval information, and the control unit 23a performs the release process based on the received approval information (S41). When the release process is completed, the control unit 23a transmits a release notification indicating that the release process is completed to the second control terminal 30b using the wireless communication unit 21a (S42).

The wireless communication unit 33b of the second control terminal 30b receives the release notification, and the information processing unit 34b displays a notification screen on the display unit 32b based on the received release notification (S43).

On the other hand, when it is determined in step S39 that another release approval request is received within a certain period of time, the approval information is not transmitted, and the control unit 23a does not perform the release process. In this case, the operator performs the process again from step S11, for example.

As described above, in the setting canceling method according to the modification example, when the first lighting fixture 20a transmits an approval request to the second control terminal 30b and the approval (approval information) is obtained from the second control terminal 30b, the canceling process (the process of separating from the first wireless communication network) is performed. The second control terminal 30b approves the detachment of the first lighting fixture 20a from the first wireless communication network on the condition that no other approval request is received from other lighting fixtures than the first lighting fixture 20a within a certain period after receiving the approval request.

In such a setting canceling method, if 2 or more lighting fixtures emit light in the same light emission pattern by accident, and each of the 2 or more lighting fixtures transmits an approval request, the canceling process is not approved. Therefore, the setting registration of the lighting fixtures including more than 2 lighting fixtures which should not be released from the setting registration can be suppressed from being released.

In example 2 of the setting canceling method, the order of the processing after the determination processing may be modified as shown in fig. 6, though not shown.

[ Effect etc. ]

Hereinafter, the invention obtained from the disclosure of the present specification will be exemplified, and effects and the like obtained by the invention will be described.

The invention 1 is a setting release method, including: a first step of turning on and off a wall switch 50 for receiving a predetermined operation to supply power to a first lighting fixture 20a belonging to a first wireless communication network; a second step of detecting that the first lighting fixture 20a turned on and off in the power supply of the predetermined mode corresponding to the predetermined operation emits light in accordance with the first light emission mode; a third step of receiving, from a user, a designation of a light emission mode from a second control terminal 30b belonging to a second wireless communication network different from the first wireless communication network, and wirelessly transmitting first information showing the designated light emission mode, that is, a second light emission mode, to the first lighting fixture 20 a; fourth, when it is determined that the second light emission pattern indicated by the first information matches the first light emission pattern, the first lighting fixture 20a performs a process of disconnecting from the first wireless communication network.

The invention 4 is the setting canceling method of the invention 1, wherein the wall switch 50 is a switch for turning on and off power supply to a plurality of lighting fixtures including the first lighting fixture 20a and 1 or more second lighting fixtures 20b belonging to the second wireless communication network, and the setting canceling method includes a step of wirelessly transmitting second information to the first lighting fixture 20a and 1 or more second lighting fixtures 20b by the second control terminal 30b after the first step and before the second step, the second information being information for causing only the first lighting fixture of the first lighting fixture and 1 or more second lighting fixtures to emit light in the second step, and the second control terminal 30b wirelessly transmitting the first information to the plurality of lighting fixtures in the third step. The second information is, for example, a light emission request in the above embodiment, and the step of wirelessly transmitting the second information is, for example, step S25.

In such a setting release method, the lighting fixture that emits light in the first light emission mode can be locked to the first lighting fixture 20a, and thus, the user can be prevented from looking wrong at the light emission mode.

The invention 5 is the setting canceling method according to any one of the inventions 1 to 4, wherein, in the first information wirelessly transmitted in the third step, a wireless communication network other than the second wireless communication network is designated as the destination.

According to such a setting release method, since the subsequent processing is not performed even if the second lighting fixture 20b receives the first information, the second lighting fixture 20b can be suppressed from performing the release processing (the setting registration of the second lighting fixture 20b is released).

The invention 6 is the setting canceling method according to any one of the inventions 1 to 5, wherein the on and off of the power supply in the predetermined mode is determined by a combination of the number of times of the on and off of the power supply and the time interval of the on and off of the power supply.

According to such a setting release method, the first lighting fixture 20a can emit light in the first light emission mode by detecting the on and off of the power supply in the predetermined pattern determined by the combination of the number of times of the on and off of the power supply and the time interval of the on and off of the power supply.

The invention 9 is the setting canceling method according to any one of the inventions 1 to 8, wherein the setting canceling method further includes a step of performing authentication processing by the second control terminal 30b, and the user is a user who succeeds in the authentication processing. The authentication process here is, for example, the authentication process of modification 1 described above.

Such a setting canceling method allows only a limited user to specify the light emission mode, and is therefore said to be a highly safe method.

The invention 10 is the setting canceling method according to any one of the inventions 1 to 9, wherein the first lighting fixture 20a that detects the on and off of the power supply in the predetermined mode is shifted to a mode in which information from the wireless communication network to which the first lighting fixture 20a does not belong is a processing object. Such a mode is, for example, a release mode.

In such a setting canceling method, the first lighting fixture 20a is in the following state: the information received from the second control terminal 30b is processed (in a state where communication with the second control terminal 30b is possible) by detecting the on/off of the power supply in the predetermined mode as a trigger. Therefore, the setting canceling method can cancel the setting registration of the first lighting fixture 20a using the second control terminal 30 b.

The invention 11 is the setting canceling method according to any one of the inventions 1 to 10, wherein in the fourth step, when it is determined that the second light emission pattern indicated by the first information matches the first light emission pattern, the first lighting fixture 20a transmits an approval request to the second control terminal 30b, and when the approval is obtained from the second control terminal 30b, the process of disconnecting from the first wireless communication network is performed, and the second control terminal 30b approves the disconnection of the first lighting fixture 20a from the first wireless communication network on the condition that no other approval request is received from other lighting fixtures than the first lighting fixture 20a within a certain period after receiving the approval request. Such a setting release method is, for example, the setting release method of modification 2 described above.

In such a setting canceling method, when the first lighting fixture 20a and the other lighting fixtures emit light in the same light emission pattern by accident, the canceling process is not approved when the first lighting fixture 20a and the other lighting fixtures each transmit an approval request. Therefore, the setting registration of the lighting fixture which should not be released from the setting registration can be suppressed from being released.

The invention 12 is the setting canceling method according to any one of the inventions 1 to 11, wherein the first lighting fixture 20a randomly determines the first lighting pattern each time it detects on and off of the power supply in the predetermined pattern.

Such a setting release method can be said to be a method having high resistance to replay attacks and the like and high security.
