The terminal device 20 is a mobile terminal that controls the lighting fixture 10 through wireless communication, and is, for example, a smart phone or a tablet terminal.

In addition, in this embodiment, the lighting fixture 10 and the terminal device 20 directly perform wireless communication. However, the lighting fixture 10 and the terminal device are not limited to this configuration, and the lighting fixture 10 and the terminal device can also be communicated through a wireless communication device such as a wireless router or a lighting device controller. 20 Indirectly performs wireless communication.

FIG. 2 is a block diagram showing the configuration of the lighting fixture 10 and the terminal device 20 shown in FIG. 1.

The lighting fixture 10 includes a communication section 11, a control section 12, a power supply section 13, and a light source section 14.

The communication unit 11 is a communication interface for performing wireless communication with the terminal device 20, and is, for example, a communication interface corresponding to a wireless LAN (Local Area Network), Bluetooth (registered trademark), or the like. In addition, in order to notify the existence of the lighting fixture 10 intermittently or continuously, the communication unit 11 sends identification information (for example, SSID (Service Set Identifier)) of the lighting fixture 10 as a beacon signal.

The power supply section 13 is a circuit that supplies power to the light source section 14, and is, for example, a power supply circuit with a dimming and toning function that converts AC power from a commercial power source into DC power and supplies it to the light source section.

The light source unit 14 is a light source that emits light, and is, for example, a plurality of LEDs (Light Emitting Diodes) connected in series and / or in parallel.

The control section 12 is a controller that performs wireless communication exchange with the terminal device 20 through the communication section 11 and controls the light source section 14 by controlling the power source section 13 based on the exchange. The control unit 12 has, for example, a ROM (Read Only Memory) for storing programs, a RAM (Random Access Memory), a processor for executing programs, a timer, and inputs connected to other components. Microcomputers (microcomputers) etc. for output ports.

The communication unit 11 may include an infrared light receiving unit that receives an infrared command sent from a remote control (remote remote control).

The terminal device 20 includes an input unit 21, a control unit 22, a memory unit 23, a communication unit 24, and a display unit 25.

The input unit 21 is an input device that receives instructions from a user, such as a touch panel and buttons.

The memory unit 23 is an auxiliary memory device that stores various information such as data and application programs, and is, for example, a non-volatile readable and writable semiconductor memory.

The communication unit 24 is a communication interface for performing wireless communication with the lighting fixture 10, and corresponds to a communication interface such as wireless LAN, Bluetooth (registered trademark), or the like. The communication unit 24 has a function of measuring a reception intensity (RSSI: Received Signal Strength Indication) of a radio wave transmitted from the lighting fixture 10.

The display unit 25 is a display that presents various information such as text and images to the user, such as an LCD (Liquid Crystal Display).

The control unit 22 is a controller that uses the input unit 21 and the display unit 25 to talk with the user, exchanges wireless communication with the lighting fixture 10 via the communication unit 24, or reads and writes various information to and from the memory unit 23. The control unit 22 includes, for example, a ROM (program storage), a RAM, a processor that executes the program, a timer, and a microcomputer (microcomputer) such as an input / output port connected to other components.

Here, as a characteristic function, the control unit 22 measures the reception intensity of the radio waves transmitted from the lighting fixture 10 through the communication unit 24 and determines whether the measured reception intensity is greater than a specific value. The specific value is set to a reception intensity that can be obtained only when the distance to the lighting fixture 10 is short (for example, within 3 m). In addition, when the control unit 22 determines that the reception intensity is greater than a specific value, the control unit 22 controls the transmission of the setting information stored in the lighting fixture 10 to the lighting fixture 10 via the communication unit 24.

The "setting information" refers to temporary information stored in the lighting fixture 10, and includes all parameters that can determine the operation or state of the lighting fixture 10. For example, it is a parameter related to wireless communication pairing, specifically, the identification information of the terminal device 20 that is stored in the lighting device 10 as the target of the wireless communication by the lighting device 10, the encryption method and password of the wireless communication, and the like. The "change of setting information" includes not only editing the setting information but also deleting.

Next, the operation of the lighting system of this embodiment configured as described above will be described. Here, it is an operation example explaining the case where "setting information" is identification information for identifying the terminal device 20 that is the object of wireless communication by the lighting fixture 10, and "change of setting information" is deletion of the identification information.

FIG. 3 shows the identification information for deleting the terminal device stored in the lighting fixture 10 by pairing. The state transition diagram of the lighting fixture 10 which was accepted by the order (hereinafter, this order is called "deletion order").

In the lighting device 10, when the power is turned on, the control unit 12 is in a state of accepting a delete instruction only for a predetermined time (for example, one minute) ("removal instruction accepting state S1"). When a certain period of time has elapsed after the power is turned on, the control unit 12 is in a state in which it cannot accept a delete command before the power is turned off ("Delete command not accepted state S2").

Thereby, by limiting the acceptance of the deletion instruction to a certain time after the power is turned on, the identification information is suppressed from being accidentally deleted or improperly deleted due to an unexpected time or person.

FIG. 4 is a flowchart showing a basic process using the terminal device 20 (that is, a control method of the lighting fixture 10) for transmitting the deletion instruction. Here, the processing performed by the control unit 22 of the terminal device 20 executing the application program stored in the memory unit 23 is displayed.

First, in the terminal device 20, the control unit 22 receives an instruction from the user via the input unit 21 to delete the identification information of the terminal device stored in the lighting fixture 10 (hereinafter, this instruction is referred to as "deletion instruction") (S10).

Upon receiving the deletion instruction, the control unit 22 confirms whether the identification information to be deleted is the identification information of itself (ie, the terminal device 20) (confirmation step S11).

As a result, when the identification information to be deleted is its own identification information (Yes at the confirmation step S11), the control unit 22 sends a deletion instruction to the lighting fixture 10 via the communication unit 24 (transmission step S12), The identification information of the object is deleted from the lighting fixture 10. In addition, if the deletion of the lighting device 10 is completed, a notification is sent from the lighting device 10 to the terminal device 20 through wireless communication, and the completion of the deletion is displayed on the display unit 25 of the terminal device 20.

On the other hand, when the identification information to be deleted is not its own identification information (No in step S11), the control unit 22 measures the self-lighting appliance 10 through the communication unit 24. Received intensity of transmitted radio waves (beacon signals, etc.) (measurement step S13).

Next, the control unit 22 determines whether the received reception intensity obtained by the measurement is greater than a specific value (decision step S14). The specific value is set to a receivable intensity only when the distance to the lighting fixture 10 is short (for example, within 3 m).

As a result, when it is determined that the reception intensity is greater than a specific value (YES in determination step S14), the control unit 22 sends a delete instruction to the lighting fixture 10 via the communication unit 24 (sending step S12), and sends the lighting fixture 10 to the lighting fixture 10 Delete the identification information of the object. After that, the lighting device 10 sends a notification to the terminal device 20 of the end of deletion from the lighting device 10 and displays the notification on the display unit 25 of the terminal device 20.

On the other hand, when it is determined that the reception intensity is not greater than a specific value (NO in determination step S14), the control unit 22 does not send a delete instruction to the lighting fixture 10 (S15).

As described above, the control method of the lighting fixture 10 by wireless communication using the terminal device 20 of this embodiment includes a measurement step S13, a determination step S14, and a transmission step S12. In the measurement step S13, the communication unit 24 for wireless communication provided in the terminal device 20 measures the reception intensity of the radio wave transmitted from the lighting fixture 10. In the determination step S14, it is determined whether the received reception intensity obtained by the measurement is greater than a specific value. In the transmission step S12, when it is determined that the reception intensity is greater than a specific value in the determination step S14, an instruction for changing the setting information stored in the lighting fixture 10 is transmitted to the lighting fixture 10 via the communication unit 24.

Thereby, the reception intensity of the radio wave transmitted from the lighting fixture 10 is measured in the terminal device 20, and when it is determined that the reception intensity is greater than a specific value, an instruction for changing the setting information stored in the lighting fixture 10 is transmitted to the lighting器 10。 The appliance 10. Therefore, only the terminal device 20 located at a short distance from the lighting device 10 can change the setting information stored in the lighting device 10, so that the terminal device that can control the lighting device 10 by tampering with other people in the neighbourhood or the like is suppressed. That is, it is safe Change the control method of the lighting fixtures stored in the setting information of the lighting fixtures throughout the country.

In addition, since the terminal device 20 that can change the setting information is not limited to the terminal device in which the identification information has been stored in the lighting device 10, even when the terminal device is lost, the setting information stored in the lighting device 10 can be changed using a new terminal device. .

Here, the setting information is identification information for identifying the terminal device 20 that is the object of wireless communication by the lighting fixture 10, and the setting information is changed for deleting the identification information.

As a result, only the terminal device 20 located closer to the lighting device 10 can delete the identification information of the terminal device stored in the lighting device 10. Therefore, tampering of the terminal device that can control the lighting fixture 10 by others in the neighbourhood or the like is suppressed.

The terminal device 20 that can change the setting information is not limited to the terminal device in which the identification information is stored in the lighting fixture 10. Therefore, even when the terminal device 20 is lost, the new terminal device can be used to delete the identification information stored in the lighting fixture 10.

The control method of the lighting fixture 10 further includes a confirmation step S11 of confirming whether the identification information to be deleted is the identification information of the terminal device 20. When it is confirmed that the identification information to be deleted is the identification information of the terminal device 20 in the confirmation step S11, the deletion instruction is sent to the lighting device 10 without going through the measurement step S13 and the determination step S14. On the other hand, when it is confirmed that the identification information to be deleted is not the identification information of the terminal device 20, the measurement step S13, the determination step S14, and the transmission step S12 are performed.

Therefore, only when the setting information stored in the lighting fixture 10 is changed by a terminal device different from the terminal device used at the time of registration, that is, only when there is a possibility of tampering with the terminal device that can control the lighting fixture 10 At this time, the judgment of the reception strength is performed.

5 to 7 are diagrams showing examples of screen display on the display section 25 of the terminal device 20 in the basic processing shown in FIG. 4 (that is, the control method of the lighting fixture 10). That is, the control of the display luminaire 10 Results of detailed display processing (display steps) in the manufacturing method.

Specifically, FIG. 5 shows an example of a screen display on the display unit 25 of the terminal device 20 before the deletion instruction is accepted in step S10 of FIG. 4. For example, it is a screen display example immediately after an application program for realizing the control method of the lighting fixture 10 according to this embodiment is started.

Here, all the lighting fixtures capable of detecting radio waves (beacon signals) by the terminal device 20 are displayed in the form of a list of two types ("registered lighting fixture 30" and "unregistered lighting fixture 40"). The control unit 22 of the terminal device 20 can exchange all the lighting equipment that detects radio waves (beacon signals) and wireless communication to display the generated information.

"Registered lighting fixture 30" is a list of lighting fixtures in which identification information of itself (terminal device 20) is registered, and includes a column of identification information of lighting fixtures ("SSID31") and the status of lighting fixtures ("state 32"). In the example in this figure, among the lighting fixtures that have identified the identification information of themselves (terminal device 20), the lighting fixture whose identification information is "Appliance A (31a)" is "on light", and the identification information is "Appliance" "B (31b)" is "light off".

In addition, the "unregistered lighting fixture 40" is a list of lighting fixtures for which identification information of itself (terminal device 20) is not registered, and includes a column of identification information of lighting fixtures ("SSID41") and the status of lighting fixtures ("state 42" ). In the example in this figure, among the lighting fixtures that have not been identified with the identification information of themselves (terminal device 20), the identification information of other terminal devices is registered in the lighting fixture whose identification information is "appliance C (41a)" ( "There is another terminal login 42a"). It was learned that the identification information of the other lighting device is not registered in the lighting device whose identification information is "Appliance D (41b)" ("No other terminal registration 42b").

In this way, by using the screen display example shown in FIG. 5, it is known which lighting device can be wirelessly communicated with, or whether the lighting device in which identification information of itself (terminal device 20) is registered and the unregistered lighting device are which one. In addition, the identification information about itself (terminal device 20) is registered It is known that the lighting fixture is in the on state, and the lighting fixture that has not registered the identification information of itself (terminal device 20) knows whether the identification information of other terminal devices is registered.

FIG. 6 is an example of a screen display on the display section 25 of the terminal device 20 in the case where the “tool C (41a)” is selected (touched screen) in FIG. 5. In addition, "appliance C (41a)" is a lighting fixture in which identification information of itself (terminal device 20) is not registered, and is a lighting fixture in which identification information of another terminal device is registered, as known from FIG.

As can be seen from the screen display example (top half) in this figure, the user can register (identification of the terminal device 20) to "appliance C" by pressing (touching the screen) the "register" button 45. Of lighting fixtures.

As can be seen from the screen display example (bottom half) in this figure, in "Appliance C", "identification information A (46a)" and "identification information B (46b)" of the terminal device have been registered and saved . In addition, it is displayed as "unremovable" for "identification information A (46a)", and "removable" for "identification information B (46b)". By pressing the "delete" button 46c, the "recognition" can be deleted Information B (46b) ". In addition, "deletable" and "non-deletable" respectively correspond to a case where it is determined that the reception intensity is greater than a specific value and a case where it is determined that the reception intensity is not greater than a specific value in the determination step S14 shown in FIG. 4.

That is, when the control unit 22 of the terminal device 20 determines that the reception strength is greater than a specific value in the determination step S14, the display setting information can be changed on the display unit 25 (display step). More specifically, as an image, the display instruction may be an image that deletes the identification information: the identification information stored in the lighting fixture 10 and the identification information identifying a communication terminal that is the object of wireless communication by the lighting fixture 10.

Therefore, based on the reception intensity, whether the identification information stored in the lighting fixture 10 can be deleted and displayed on the display section 25, when the identification method cannot be deleted, the user can perceive the Status to avoid confusion.

FIG. 7 is an example of a screen display on the display section 25 of the terminal device 20 when the “delete” button 46c is pressed in FIG. 6. In addition, the "Delete" button 46c is a button for deleting the "identification information B (46b)" of another terminal device, as known from FIG. Since the distance to the lighting fixture ("appliance C") in which the "identification information B (46b)" is registered is short, it is determined that the identification information can be deleted by the terminal device 20 and the "delete" button 46c is displayed.

As can be seen from the screen display example of this figure, if the "Delete" button 46c is pressed, an image requesting confirmation of deletion of the "identification information B" is displayed (here is the message "Are you sure?"). Therefore, the user can delete or cancel the "identification information B" by pressing "Yes (48a)" or "No (48b)". The execution of the so-called "identification information B" is that the terminal device 20 sends a deletion instruction of "identification information B" to the lighting fixture ("appliance C").

In this way, when the control unit 22 of the terminal device 20 determines that the reception strength is greater than a specific value in the determination step S14, it performs a confirmation screen display before sending the delete instruction. That is, an image requesting confirmation of deletion of the following identification information is displayed on the display unit 25 (display step): identification information stored in the lighting fixture 10 and identification information identifying a communication terminal that is the object of wireless communication by the lighting fixture 10 .

Therefore, when the identification information stored in the lighting fixture 10 is deleted, since confirmation of the deletion is required, the user may notice the error before deleting the identification information when performing a wrong operation.

As described above, the control method of the lighting fixture 10 by wireless communication using the terminal device 20 of this embodiment includes a measurement step S13, a determination step S14, and a transmission step S12. In the measurement step S13, the communication unit 24 for wireless communication provided in the terminal device 20 measures the reception intensity of the radio wave transmitted from the lighting fixture 10. In the determination step S14, the measurement result is determined. Whether the receiving strength is greater than a certain value. In the transmission step S12, when it is determined that the reception intensity is greater than a specific value in the determination step S14, an instruction for changing the setting information stored in the lighting fixture 10 is transmitted to the lighting fixture 10 via the communication unit 24.

In the present embodiment, the program held by the terminal device 20 is a program for causing a computer to execute the control method of the lighting apparatus 10 described above.

The terminal device 20 according to this embodiment is a terminal device 20 that controls the lighting fixture 10 by wireless communication, and includes a communication unit 24 and a control unit 22 that perform wireless communication with the lighting fixture 10. The control unit 22 measures the reception intensity of the radio waves transmitted from the lighting fixture 10 by the communication unit 24, and determines whether the measured reception intensity is greater than a specific value. In addition, when it is determined that the reception intensity is greater than a specific value, the communication unit 24 performs control to send the instruction for changing the setting information stored in the lighting fixture 10 to the lighting fixture 10.

With such a control method, program, and terminal device 20 of the lighting device 10, the terminal device 20 measures the reception intensity of the radio wave transmitted from the lighting device 10. When the reception intensity is greater than a specific value, an instruction to change the setting information stored in the lighting fixture 10 is sent to the lighting fixture 10. Therefore, only the terminal device 20 located at a short distance from the self-lighting device 10 can change the setting information stored in the lighting device 10, thereby suppressing tampering of the terminal device that can control the lighting device 10 by other people in the neighborhood. In other words, a control method, a program, and a terminal device for a lighting fixture that can safely change setting information stored in the lighting fixture are realized.

Moreover, since the terminal device 20 that can change the setting information is not limited to the terminal device whose identification information has been stored in the lighting device 10, even when the terminal device is lost, the setting information stored in the lighting device 10 can be changed using a new terminal device. .

The control method and terminal device of the lighting fixture according to the present invention have been described based on the embodiment, but the present invention is not limited to the embodiment. As long as it does not depart from the owner of the present invention It is intended that those skilled in the art apply various changes that come to mind to this embodiment, or another embodiment constructed by combining a part of the constituent elements of the embodiment, which is also included in the scope of the present invention.

For example, in the embodiment described above, the lighting fixture 10 has been described as an example of the lighting fixture, but the lighting control device may be used as the lighting fixture or the like. The lighting control device is a lighting controller that controls the lighting device 10 according to an instruction from the terminal device 20, and has at least a function equivalent to the control unit 12 of the lighting device 10 in the above embodiment. The lighting control device can control not only one lighting fixture, but also a plurality of lighting fixtures. The present invention can also be applied to a lighting system including a lighting control device instead of the lighting device of the above embodiment, or a lighting system including a lighting control device in addition to the lighting device.

Furthermore, in the above-mentioned embodiment, as an example of "change of setting information" stored in the lighting fixture 10, an example of deleting the identification information of the terminal device is described, but "change of setting information" is not limited to this. Any parameter that can be stored in the lighting fixture 10 can be changed, or the identification information of the lighting fixture 10 itself can be changed, or the encryption method and password in wireless communication between the lighting fixture 10 and the terminal device 20 can be changed . By the control method of the present invention, these parameters are inhibited from being improperly changed by others.

In the above embodiment, the terminal device 20 confirms whether the identification information to be deleted is its own identification information (confirmation step S11), but this confirmation step S11 is not necessary. Regardless of whether the identification information to be deleted is its own identification information, the measurement step S13 and the determination step S14 can generally be performed. The reason is that even in a case where the identification information to be deleted is its own identification information, the terminal device 20 can be easily obtained at a relatively short distance from the lighting fixture 10.

Moreover, in the above-mentioned embodiment, the method of controlling the lighting fixture 10 is realized by a program (application program) held by the terminal device 20. The program can also be held in the terminal device 20 in advance, or it can be borrowed Downloaded by users via the Internet, etc. In addition, the program can also be recorded and circulated on a computer-readable recording medium such as a compact disc read-only memory (CD-ROM), or it can be distributed through a network via transmission.
