Hereinafter, embodiments will be described with reference to the drawings.

FIG. 1 shows the configuration of the lighting system of the present embodiment. As shown in FIG. 1, the lighting system 100 includes a plurality of lighting devices 10 (10a to 10i) installed on the ceiling surface of the lighting space 1 and a terminal 20 communicatively connected to the lighting device 10. To. Specifically, the lighting device 10 is an emergency light that lights up in an emergency such as a power failure, and is installed on the ceiling surface at predetermined intervals.

In the present embodiment, the case where nine lighting devices 10 are arranged will be described, but the present invention is not limited to this, and a plurality of (n (n is an integer)) lighting devices may be arranged.

The terminal 20 is a mobile terminal such as a smartphone or a tablet terminal, and is configured to enable wireless communication with the lighting device 10. The terminal 20 has a display screen and has a function of displaying a layout diagram showing the layout position of the lighting device 10 on the terminal screen.

Further, the communication method between the lighting devices 10a to 10i and between the lighting devices 10a to 10i and the terminal 20 is, for example, a wireless communication method capable of a mesh network such as BLE (Bluetooth (registered trademark) Low Energy). Is.

2 and 3 show the configuration of the lighting device 10. The lighting device 10 includes a light source 11, a storage battery 12, a control unit 13, a storage unit 15, and a transmission / reception unit 14, which are housed inside the housing 16. Further, on the back side of the housing 16, a terminal block 19 connected to the external power supply 18 is provided.

As the light source 11, for example, a light emitting module composed of a semiconductor light emitting element such as a light emitting diode (LED) or a laser diode, or an organic EL element (OLED) is used, and is configured to emit white light. The light source 11 has a transparent glass or resin lens that controls the light distribution of the light emitted from the light emitting module.

The storage battery 12 is a battery that can be attached to and detached from the inside of the housing, and is a rechargeable secondary battery such as a Nicad battery, a nickel hydrogen battery, or a lithium ion battery.

The external power supply 18 can be an arbitrary power supply such as a commercial AC power supply or a DC power supply. In this embodiment, the external power supply is a commercial AC power supply.

The terminal block 19 is provided on the back side of the housing 16 and electrically connects the external power supply 18 and the control unit 13 via an electric wire (not shown).

The control unit 13 is electrically connected to the external power source 18 and the storage battery 12, and supplies the electric power from the external power source 18 and the storage battery 12 to the light source 11, the transmission / reception unit 14, and the like.

The electric power supplied from the external power supply 18 is supplied to the control unit 13 via the terminal block 19. The control unit 13 controls the storage battery 12 to be charged by the external power source 18 during normal use and to supply the electric power of the storage battery 12 to the light source 11 in an emergency. Further, in an emergency, the power of the storage battery 12 may be controlled to be supplied to the transmission / reception unit 14.

Further, the control unit 13 includes an inspection unit (not shown) and a storage unit 15, so that the inspection information inspected by the inspection unit is stored in the storage unit 15 and the inspection information is output from the transmission / reception unit 14 to the external terminal. Can be controlled.

The inspection unit inspects whether or not the storage battery 12 operates normally by detecting the voltage, current, temperature, discharge time, and number of discharges of the storage battery 12, and outputs these inspection information to the storage unit 15.

The storage unit 15 is composed of a volatile memory, a non-volatile memory, and the like. The storage unit 15 stores an identification number indicating itself. The identification number is identification information for identifying the lighting device 10, and is, for example, a unique address such as a MAC address. This identification number may be stored in the storage unit 15 at the time of manufacturing the lighting device 10. In addition, the storage unit 15 stores the identification information of the terminal 20 transmitted from the terminal 20 described later.

The transmission / reception unit 14 is an interface for transmitting / receiving data by wireless communication. The transmitter / receiver 14 is, for example, an interface that supports Bluetooth® connection. Here, it is assumed that BLE communication is supported. The transmission / reception unit 14 transmits information such as an identification number and an inspection of the own device, which is connected to the control unit 13 and is stored in the storage unit 15, to the terminal 20 as a wireless signal. When the control unit 13 transmits the identification number of the lighting device from the transmission / reception unit 14, the light source 11 blinks for a certain period of time. For example, by blinking the light source 11 for 10 seconds after transmitting the identification signal from the transmission / reception unit 14, the operator can visually confirm the lighting device to which the identification number has been transmitted.

The terminal 20 is a mobile terminal such as a smartphone or a tablet terminal, and has a transmission / reception unit (not shown) for receiving a signal transmitted from the lighting device 10 or transmitting a signal of the own device.

When the transmitter / receiver transmits a signal of its own unit, it may be transmitted by a weak radio wave. Further, the transmission / reception unit is provided with a directional antenna (not shown), and the signal of the own unit may be transmitted from this antenna. Thereby, for example, when a signal is transmitted from the terminal 20 to the lighting device 10i as shown in FIG. 1, it is possible to suppress reception by the adjacent lighting devices 10h, 10e, and 10f.

Further, the terminal 20 stores an identification number indicating itself in a storage unit (not shown) of the own machine. The identification number is identification information that identifies the terminal 20, and is, for example, a unique address such as a MAC address. This identification number may be stored in the storage unit at the time of manufacturing the terminal 20.

Further, as shown in FIG. 4, the terminal 20 stores the arrangement position 21 of the lighting device 10 in the storage unit of the own machine, and displays the arrangement drawing 22 showing the arrangement position 21 on the display screen 23 of the terminal. .. Here, numbers 1 to 9 are assigned to the arrangement positions 21 of the arrangement positions 21. In the embodiment, a number is assigned to the arrangement position 21, but the number is not limited to this, and for example, characters may be used. Hereinafter, the number assigned to the placement position 21 will be referred to as placement position information.

The display screen 23 of the terminal 20 is, for example, a liquid crystal monitor or the like and is composed of a touch panel or the like, and can be operated by an operator by tapping the display screen 23. The layout drawing 22 is a layout drawing corresponding to a plan view of the illumination space 1. The layout drawing 22 is stored in the terminal 20 when the lighting device 10 is installed. For example, an operator can store the layout drawing 22 in the storage unit of the terminal 20 before installing the lighting device 10.

Immediately after the lighting device 10 is installed on the ceiling surface, the arrangement position 21 in the layout drawing 22 and the identification number of the lighting device 10 are not associated with each other. Therefore, it is necessary to register the identification number of the lighting device 10 at the arrangement position 21 in the arrangement drawing 22 by communicating the terminal 20 with the lighting device 10.

Specifically, the operator carries the terminal 20 and moves to the vicinity of the lighting device 10, and taps the arrangement position 21 of the arrangement FIG. 22 as shown in FIG. Here, it is assumed that the worker selects the first arrangement position 21. The terminal 20 transmits the first information given to the arrangement position 21 from the transmission / reception unit, that is, the arrangement position information. The lighting device 10a that has received the arrangement position information transmitted from the terminal 20 stores the arrangement position information of the received terminal 20 in the storage unit 15, and transmits the identification number of its own device to the terminal 20.

When the terminal 20 receives the identification number transmitted from the lighting device 10a, the terminal 20 stores the identification number of the lighting device 10a in the storage unit of its own unit, and registers the identification number at the first arrangement position 21 as shown in FIG. To do. When the registration of the identification number is completed, the terminal 20 transmits a signal indicating the completion of registration (hereinafter referred to as a registration completion signal). Upon receiving this registration completion signal, the lighting device 10a stops receiving the arrangement position information of the terminal 20. By repeating this step, as shown in FIG. 6, the arrangement position of the lighting devices 10a to 10i can be associated with the identification number.

On the other hand, when the terminal 20 receives the identification numbers from the plurality of lighting devices, the terminal 20 creates and displays the received identification number list 24 on the display screen 23 as shown in FIG. The operator taps the identification number displayed in the identification number list 24, and by tapping the registration button 25, the terminal 20 stores the identification number of the lighting device 10a in the storage unit of the own machine, and as shown in FIG. The identification number is registered in the first arrangement position 21. When the registration of the identification number is completed, the terminal 20 transmits a signal indicating the completion of registration (hereinafter referred to as a registration completion signal).

Further, when the identification number displayed in the list 24 shown in FIG. 7 is tapped and the exclusion button 26 is tapped, the terminal 20 gives a signal (hereinafter, referred to as an exclusion signal) to the lighting device 10 to stop receiving the arrangement position information. It is transmitted and the identification number of the lighting device 10 is deleted from the identification number list 24. For example, when deleting the identification number of the lighting device 10b from the identification number list 24 that has received the identification numbers of the lighting devices 10a and 10b as shown in FIG. 7, the operator taps 10b of the identification number list 24 and presses the exclusion button. When 26 is tapped, an exclusion signal is transmitted to the lighting device 10b. Upon receiving this exclusion signal, the lighting device 10 stops blinking of the light source 11 and stops receiving the arrangement position information transmitted from the terminal 20 for a certain period of time. After transmitting the exclusion signal, the terminal 20 deletes the identification number of the lighting device 10b from the identification number list 24. As a result, this operation is performed even when the lighting device 10 other than the lighting device 10a receives the placement position information of the terminal 20 in the step of associating the identification number of the lighting device 10a with the placement position as described in detail later. Therefore, it can be controlled not to receive for a certain period of time.

Further, a signal for stopping the blinking of the light source 11 of the lighting device 10 may be transmitted by long-tapping the identification number in the identification number list 24 in FIG. 7 (hereinafter, referred to as a blinking stop signal). For example, when the identification numbers of the lighting devices 10a and 10b are received as shown in FIG. 7, when the operator long-tap 10b of the identification number list 24, a blinking stop signal is transmitted to the lighting device 10b, and the blinking stop signal is transmitted. The received lighting device 10b stops blinking. As a result, the lighting device 10a is blinking, but the lighting device 10b stops blinking, so that the operator can visually determine which lighting device the lighting device 10b possessing the identification number 10b is. .. Here, when it is desired to register the lighting device 10b at the first arrangement position 21, the lighting device 10b is registered at the first arrangement position 21 by pressing the registration button 25. When not registered in the first arrangement position 21, the exclusion signal is transmitted to the lighting device 10b by pressing the exclusion button 26, and the identification number 10b is deleted from the identification information list 24 of the own machine.

Next, a flow in which the operator associates the identification numbers of the lighting devices 10a to 10i with the arrangement positions using the lighting system 100 will be described with reference to FIG. Here, immediately after the lighting devices 10a to 10i are installed on the ceiling of the lighting space 1, the layout drawing 22 of the terminal 20 and the lighting devices 10a to 10i are not associated with each other.

First, the operator starts supplying electric power from the external power source 18 and drives the lighting devices 10a to 10i (S1). When the power is supplied from the external power source 18, the lighting devices 10a to 10i enter the reception state and start receiving the arrangement position information of the terminal 20 (S2). The operator moves directly under the lighting device 10a and selects one of the arrangement positions 21 of the arrangement drawing 22 of the terminal 20 (FIG. 4). For example, suppose that the first arrangement position 21 is selected. The terminal 20 in which the first arrangement position 21 is selected transmits the identification number of its own device to the lighting device 10a (S3). The lighting device 10a stores the arrangement position information received from the terminal 20 in the storage unit 15 (S4).

Next, the lighting device 10a transmits the identification number of the own device from the storage unit 15 to the calling terminal 20 and blinks the light source 11 (S5). The terminal 20 stores the identification number of the lighting device 10a in the storage unit, and registers the identification number of the lighting device 10a at the arrangement position 21 of the layout drawing 22 (FIG. 5) (S6). When the registration of the identification number is completed, the terminal 20 transmits the registration completion signal to the lighting device 10 (S7). Upon receiving this registration completion signal, the lighting device 10a stops receiving the arrangement position information of the terminal 20 (S8). Similarly, the identification numbers of the lighting devices 10b to 10i are registered in the placement positions 21 by performing the operations S1 to S8 in the lighting devices 10b to 10i corresponding to the placement positions 21 (FIG. 6).

Next, when the operator associates the identification number of the lighting device 10a with the placement position using the lighting system 100, the operation when the lighting devices 10a and 10b receive the placement position information transmitted by the terminal 20 is shown in FIG. This will be described with reference to FIG. Here, immediately after the lighting devices 10a to 10i are installed on the ceiling of the lighting space 1, the layout drawing 22 of the terminal 20 and the lighting devices 10a to 10i are not associated with each other.

S1 to S3 of FIG. 9 perform the same operation as S1 to S3 of FIG. When the lighting devices 10a and 10b receive the placement position information transmitted from the terminal 20 in S3, the lighting devices 10a and 10b store the placement position information of the terminal 20 in their respective storage units 15 (S4). Next, the lighting devices 10a and 10b transmit the identification number of the own device from the storage unit 15 to the calling terminal 20 and blink the light source 11 (S5). When the terminal 20 receives the identification numbers of the lighting devices 10a and 10b, the terminal 20 creates the identification number list 24 and displays it on the display screen 23 (FIGS. 7) and (S6). The operator taps 10b of the identification number list 24 and taps the exclusion button 26 to transmit an exclusion signal from the terminal 20 to the lighting device 10b (S7). The lighting device 10b that has received the exclusion signal stops blinking of the light source 11 and is in a state of not receiving the arrangement position information of the terminal 20 for a certain period of time (S8). After transmitting the exclusion signal, the terminal 20 deletes the identification number of the lighting device 10b from the identification number list 24 (S9). When the operator taps 10a in the list 24 of the terminal 20 and taps the registration button 25, the identification number of the lighting device 10a is stored in the storage unit, and the identification number of the lighting device 10a is registered in the arrangement position 21 of the layout drawing 22. (FIG. 5) (S10). When the registration of the identification number is completed, the terminal 20 transmits the registration completion signal to the lighting device 10 (S11). Upon receiving this registration completion signal, the lighting device 10a stops receiving the arrangement position information of the terminal 20 (S12). Since the lighting device 10b is in a state where it can receive the arrangement position information of the terminal 20 after a certain period of time has elapsed, after a certain period of time, the lighting devices 10b to 10i corresponding to the arrangement positions 21 to 9 are similarly subjected to S1 to S5. By performing the above operations, the identification numbers of the lighting devices 10b to 10i are registered in the arrangement position 21 (FIG. 6).

In this way, by transmitting the arrangement position information from the terminal 20 having the arrangement drawing 21 and communicating with the arbitrary lighting device 10, the arrangement position of the lighting device 10 and the identification number can be easily associated with each other. Further, since the lighting device 10 transmits the identification number of the own device after receiving the arrangement position information of the terminal 20, it is possible to suppress the transmission of the identification number more than necessary.

Further, the lighting device 10 can provide the position information by storing the arrangement position information. For example, the lighting device 10 installed in a large facility such as a department store can provide the position information to the user by transmitting the arrangement position information of the own unit from the transmission / reception unit 14. Further, when the power supply from the external power supply 18 is cut off and a power failure occurs due to a disaster or the like, the power transmission / reception unit 14 transmits the arrangement position information of the own unit stored in the storage unit 15 by the power supply from the storage battery 12. This makes it possible to provide the evacuees with location information.

Although embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other embodiments, and various omissions, replacements, and changes can be made without departing from the gist of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are also included in the scope of the invention described in the claims and the equivalent scope thereof.
