(Handover process procedure)
Next, with reference to FIG. 7, a procedure of a handover process by the lighting device 10 (control unit 13) will be described. FIG. 7 is a flowchart illustrating an example of a procedure of handover processing by the lighting device 10 according to the embodiment. It should be noted that the following handover processing is processing for any one area A out of a plurality of areas A-1 to A-5 . . . In practice, the following handover processing is performed for all areas A of a plurality of areas A-1 to A-5 . . .

As shown in FIG. 7, in the takeover process by the lighting device 10, first, the control unit 13 acquires confirmation item information from the server device 30 (step S101). Further, the control unit 13 acquires confirmation information from the server device 30 (step S102).

Note that the control unit 13 may reverse the order of the process of acquiring the confirmation item information (step S101) and the process of acquiring the confirmation information (step S102), or the process of acquiring the confirmation item information (step S101). ) and the process of acquiring the confirmation information (step S102) may be performed at the same time.

Next, the control unit 13 compares the confirmation item information and confirmation information acquired from the server device 30, and determines whether or not the confirmation information satisfies a predetermined condition (step S103).

If the control unit 13 determines in the process of step S103 that the confirmation information satisfies the predetermined condition (step S103: Yes), the control unit 13 determines that the control to the lighting unit 12 is “allowed”, and the operation unit of the switch device 20 22 is detected to turn off the lighting unit 12 (step S104), the lighting unit 12 is turned off (step S104). When the lighting unit 12 is turned off, the control unit 13 ends the handover process.

In this way, the user can understand that there is no person in this area A by turning off the lighting unit 12 by the turning off operation, and the handover is completed.

When the control unit 13 determines that the confirmation information does not satisfy the predetermined condition in the process of step S103 (step S103: No), the control unit 13 determines that the control to the lighting unit 12 is “no”. Even if an operation to turn off the lighting unit 12 is detected with respect to the operation unit 22 (step S105), the lighting unit 12 is not turned off (step S106). The control unit 13 ends the handover process without turning off the illumination unit 12 .

In this way, the user can recognize that there is a person in the area A by not turning off the lighting unit 12 by the turning off operation, and in this case, the handover is not completed.

By repeating such handover processing until the last user becomes the last user, the handover is finally completed for all areas A. Therefore, it is possible to prevent failures such as forgetting to turn off the lighting device 10 due to forgetting to take over. .

Note that the control unit 13 may reset the confirmation information stored in the server device 30, for example, at a predetermined time (for example, 7:00 am) on the day after the takeover process is performed.

In addition, the control unit 13 resets the confirmation information stored in the server device 30, for example, when a predetermined time (for example, 6 hours) elapses after the last user updates. You may do so. Also, for example, when the first person to come to work on the next day of the handover process receives the floor key from the management room, etc., the confirmation information stored in the server device 30 is reset by the person in charge of the management room. may be reset.

As described above, the lighting device 10 according to the embodiment includes the lighting section 12 and the control section 13 . The illumination unit 12 emits illumination light in any one of a plurality of preset areas A (A-1 to A-5 . . . ). The control unit 13 controls the illumination unit 12 based on the user's operation, and determines whether confirmation information corresponding to confirmation items managed by the server device 30, which is transmitted from the terminal device 40, satisfies a predetermined condition. determines whether or not to control the lighting unit 12 by.

According to such a configuration, for example, the operation by the user is accepted only when the predetermined conditions are satisfied in each of the areas A-1 to A-5 . . . It is possible to control not to accept the operation by the user. When a user's operation is not accepted in an area A that does not satisfy a predetermined condition, the user can understand that this area A does not meet the predetermined condition by not accepting an operation in a certain area A. can. That is, the user can easily grasp the current situation of each area A-1 to A-5.

In addition, in the lighting device 10 according to the embodiment, the control unit 13 does not control the lighting unit 12 even if the user's operation is performed when the confirmation information does not satisfy the predetermined condition.

According to such a configuration, since the user's operation is not accepted in the area A that does not satisfy the predetermined conditions, the user can easily grasp that the area A does not satisfy the predetermined conditions. .

Also, the lighting system 1 according to the embodiment includes a lighting device 10 , a server device 30 , a terminal device 40 and a control section 13 . The illumination device 10 includes an illumination unit 12 that emits illumination light, and is installed in each of a plurality of preset areas A (A-1 to A-5 . . . ). The server device 30 manages the confirmation items that are the handover items of the area A. FIG. The terminal device 40 transmits confirmation information indicating the transfer completion status of the area A to the server device 30 . The control unit 13 determines whether or not to control the lighting unit 12 depending on whether or not the confirmation information corresponding to the confirmation item satisfies a predetermined condition.

According to such a configuration, for example, the operation by the user is accepted only when the predetermined conditions are satisfied in each of the areas A-1 to A-5 . . . It is possible to control not to accept the operation by the user. When a user's operation is not accepted in an area A that does not satisfy a predetermined condition, the user can understand that this area A does not meet the predetermined condition by not accepting an operation in a certain area A. can. That is, the user can easily grasp the current situation of each area A-1 to A-5.

In the above-described embodiment, the updater information is stored in the storage unit 32 (updater information storage unit 323) of the server device 30. FIG. The name of the last user (updater) and information on the update time are stored in the updater information. In other words, the server device 30 stores the return time of the last updater. Such information can be used to encourage reduction of working hours from the viewpoint of preventing overwork.

For example, if the updaters, including the last updater, stored in the server device 30 seem to be working overtime for a long time, the terminal The operation unit 43 and the display unit 44 of the device 40 are displayed in a color different from usual, so as to call attention to the updater.

In addition, since each of the plurality of lighting devices 10 has an individual control address, the control unit 13, for example, determines the route from the area A where the last user is to the main area A assigned to the office. For example, the light may be turned on for a predetermined time (a time during which the main area A can be reached from the area A where the last user was). In this case, the control unit 13 can also perform dimming while suppressing the illuminance of the illumination light, the illumination range, and the like, for example. Moreover, such route lighting may be controlled by the server device 30 side.

Also, for example, in the case of a breaker on a distribution board that can detect whether it is on or off using a sensor, for example, after the user has turned off the breaker, another user has to turn on the breaker again to perform work. For this reason, the information managed by the server device 30 and the detection result from the sensor may not match. In such a case, for example, by displaying an alert on the display unit 44 of the terminal device 40, the user can be prompted to confirm again. Note that the alert display includes, for example, changing the color of the circular operating portion 43a of the operating portion 43 such as an on/off switch to a color different from usual.

Although the embodiment of the present invention has been described above, this embodiment is presented as an example and is not intended to limit the scope of the invention. This embodiment can be implemented in various other forms, and various omissions, replacements, and modifications can be made without departing from the scope of the invention. As well as being included in the scope and gist of the invention, this embodiment is included in the scope of the invention described in the claims and equivalents thereof.
