Description

The present invention relates to lighting fixtures, and in particular to lighting fixtures that transmit beacon signals.

Patent Document 1 discloses a lighting fixture capable of transmitting a beacon signal. A beacon signal usually contains location information for identifying the transmission location. By having this location information received by an information terminal or the like, it is possible to provide services such as displaying advertising images appropriate to that location on the display of the user's information terminal. To enable the transmission of a beacon signal, in the lighting fixture of Patent Document 1, a board equipped with the function of transmitting a beacon signal is fixed inside a straight tube lamp that is detachable from the main body of the lighting fixture.

JP 2017-37812 A

Lighting fixtures equipped with the function of transmitting a beacon signal are usually delivered to the installation site with the contents of the beacon signal they transmit preset by the manufacturer or the like, and are then installed at the installation location. However, at the installation site where the lighting fixture is actually installed, it is conceivable that the location information of the beacon signal and the actual transmission location, which is the location where the lighting fixture is attached, will differ.

In this case, in the above-mentioned lighting fixture, it is possible to change the actual transmission position of the beacon signal by removing the straight tube lamp and attaching it to another lighting fixture nearby. However, since it can only be attached to a lighting fixture that has a straight tube lamp of the same size and emission color so that the emitted color does not change, there are significant restrictions on fine-tuning and changing the transmission position.

In view of the above problems, the present invention aims to provide a lighting fixture that allows the transmission location to be changed more flexibly than conventional lighting fixtures.

In order to solve the above problems, the lighting device of the present invention is a lighting device comprising a module for wireless communication, a power supply unit, and a light source unit, wherein the module comprises a first circuit unit and a second circuit unit, the first circuit unit receives a lighting control instruction and outputs a control signal to the power supply unit for performing an operation indicated by the lighting control instruction, the power supply unit supplies power corresponding to the control signal to the light source unit, the first circuit unit receives information necessary for the communication operation of the second circuit unit and is capable of controlling the second circuit unit by transmitting the information from the first circuit unit to the second circuit unit via a signal line within the module , and the second circuit unit transmits a beacon signal indicating the transmission position.

With the above-mentioned configuration, the lighting device of the present invention can provide a lighting device that can change the transmission position more flexibly than conventional lighting devices.

The following describes a lighting system 1 according to one embodiment of the present invention with reference to the drawings.

1. First embodiment
<1.1. Overview>
FIG. 1 is a diagram showing a configuration of a lighting system 1.

As shown in FIG. 1, the lighting system 1 includes a plurality of lighting fixtures 2a, 2b, ..., 2c (hereinafter collectively referred to as "lighting fixtures 2"), a user terminal device 9a, and a lighting control device 9b.

Lighting fixtures 2 are lighting fixtures that each have the function of transmitting a beacon signal. Lighting fixtures 2b, ..., 2c have the same configuration as lighting fixture 2a. Below, lighting fixture 2a will be mainly described, and lighting fixtures 2b, ..., 2c will be described as necessary.

The user terminal device 9a and the lighting control device 9b are both information processing devices equipped with a display, such as a smartphone, for example. The user terminal device 9a receives a beacon signal transmitted by the lighting fixture 2 via wireless communication (as an example, a beacon signal 11a transmitted by the lighting fixture 2a, as shown in FIG. 1 by a dashed line), and performs processing according to the received beacon signal, such as launching a different application or displaying an image depending on the content of the received beacon signal.

The lighting control device 9b is used to transmit, in accordance with instructions input by a user, instructions (hereinafter referred to as "lighting control instructions") to the lighting fixtures 2 via wireless communication (one example of which is wireless communication 12a, which is shown diagrammatically by a dashed line in FIG. 1) to perform lighting control such as turning on and off the light source, changing the dimming rate, and changing the light emission color temperature.

The wireless communication (mainly transmission of beacon signals) between the lighting fixtures 2 and the user terminal device 9a, and the wireless communication between the lighting fixtures 2 and the lighting control device 9b are based on the Bluetooth (registered trademark) Low Energy (hereinafter referred to as "BLE") specification, but are not limited to this and wireless communication based on other specifications may be performed. In addition, the lighting fixtures 2, the user terminal device 9a, and the lighting control device 9b can form a mesh network using BLE, and can communicate with each other directly or indirectly through the mesh network.

As shown in FIG. 1, the lighting fixture 2a includes a fixture body 4a, a power supply unit 5a, and a wireless module (hereinafter referred to as "WM") 7a. Note that the lighting fixture 2a has a separate structure (external power supply type) for the fixture body 4a and the power supply unit 5a, but is not limited to this, and the lighting fixture 2a may have a structure in which the power supply unit 5a is built in (built-in power supply type).

Figure 2 is an oblique view showing the appearance of the power supply unit 5a.

Figure 3(a) is a block diagram showing the configuration of lighting fixture 2a.

As shown in FIG. 2, the power supply unit 5a includes a power supply main unit 50a and an electric wire 51a, and is electrically connected to the instrument main unit 4a by connecting the electric wire 51a to the instrument main unit 4a. In addition, the power supply main unit 50a includes a socket unit 53a to which the WM 7a can be detached, as shown in FIG. 3(a).

WM7a has a function of transmitting a beacon signal. The beacon signal includes information indicating the transmission position of the beacon signal. Here, for example, when the lighting fixture 2 is attached to a specified installation position during construction, the installation position of the lighting fixture 2 may differ from that at the time of design, and a discrepancy may occur between the installation position and the transmission position indicated by the beacon signal emitted from the lighting fixture 2.

Even in such a case, by changing the lighting fixture 2 to which the WM7a is attached to one whose installation position is closer to the transmission position indicated by the beacon signal, the position where the beacon signal is actually transmitted (corresponding to the installation position of the lighting fixture 2) can be brought closer to the transmission position indicated by the beacon signal.

If a tube lamp were configured to emit a beacon signal, problems could arise when trying to change the tube lamp to be installed in a different lighting fixture, such as a change in the color of the light emitted from the original tube lamp or the tube lamp being unable to be installed in the first place due to a difference in size.

In the lighting fixture 2, the WM7a that emits the beacon signal is configured to be detachable, so even if it is attached to another lighting fixture 2, the light color of that lighting fixture 2, the size of the straight tube lamp, etc. will not change, making it possible to flexibly change the actual transmission position of the beacon signal.

In addition, if the lighting fixture 2 is equipped with a wireless module that does not have the function of transmitting a beacon signal, the lighting fixture 2 can be easily converted to have a beacon transmission function by replacing the wireless module with WM7a.

The components of the lighting system 1 are described in more detail below.

1.2. Configuration
<1.2.1. Lighting equipment 2a>
As shown in FIG. 3A, the lighting fixture 2a includes a fixture body 4a, a power supply device 5a, and a WM 7a.

<Apparatus body 4a>
The fixture body 4a includes a light source unit 41a. The light source unit 41a includes a light source configured with an LED and a light source board, which is a circuit board on which the light source is arranged. The light source may be configured with a device other than an LED, such as an organic EL (Electro Luminescence) device, as long as it functions as a light source for illumination. The light source unit 41a performs operations such as turning on and off the light source, changing the dimming rate, and adjusting the color, depending on the power supplied from the power supply unit 54a of the power supply device 5a via the electric wire 51a.

<Power supply device 5a>
As shown in FIGS. 2 and 3A, the power supply device 5a includes a power supply main body 50a and electric wires 51a, and includes a socket portion 53a and a power supply portion 54a within the power supply main body 50a.

The power supply unit 54a converts the power supplied from outside the lighting device 2 into power corresponding to the lighting control signal received from the WM 7a, and supplies it to the light source unit 41a to perform dimming control, color adjustment control, etc.

The socket portion 53a is a socket into which the WM7a is inserted, and has a number of terminals that are electrically connected to the terminals of the terminal portion 75a of the WM7a when the WM7a is inserted. The multiple terminals are electrically connected to the power supply portion 54a, and when the WM7a is inserted into the socket portion 53a, the WM7a and the power supply portion 54a are electrically connected.

<WM7a>
The WM 7a is a module that performs wireless communication. The WM 7a is an independent device that operates by receiving power supply and is configured to be detachable from the socket unit 53a. The WM 7a has a lighting control function and a beacon signal transmission function.

The lighting control function receives lighting control instructions from the lighting control device 9b via wireless communication, and controls the turning on and off of the light source unit 41a, changing the dimming rate, adjusting the color, etc., according to the received lighting control instructions.

The beacon signal transmission function is a function that transmits a beacon signal to the outside world using wireless communication.

Figure 4 (a) shows the configuration of WM7a when disassembled.

WM 7a has a shape including a first housing part 701a, a second housing part 702a, and a substrate part 703a, as shown in Fig. 4(a). The first housing part 701a and the second housing part 702a are fitted together to form a housing, and the substrate part 703a is fixed inside the housing. The substrate part 703a is a plate-like member on which components are mounted. Components are mounted mainly on one side of the substrate part 703a (hereinafter, the surface on which components are mainly mounted is referred to as the "mounting surface").

Figure 4(b) is a schematic diagram showing the mounting surface of the substrate portion 703a.

Figure 5 is a block diagram showing the functional configuration of WM7a.

As shown in Figures 4(b) and 5, the substrate portion 703a includes a first circuit portion 71a, a second circuit portion 72a, and a terminal portion 75a.

<First Circuit Section 71a and Second Circuit Section 72a>
The first circuit unit 71a and the second circuit unit 72a are the same circuit, but are controlled by different programs. The first circuit unit 71a realizes a lighting control function by executing a lighting control program, and the second circuit unit 72a realizes a beacon signal transmission function by executing a beacon signal transmission program. By using the same circuit, the lighting control circuit can be reused and used as a circuit for transmitting a beacon signal, thereby shortening the development period of the WM7a.

The first circuit section 71a that realizes the lighting control function and the second circuit section 72a that realizes the beacon signal transmission function each operate independently. This is to avoid the fact that, since there are cases where a beacon signal needs to be transmitted at short intervals, if a single circuit were to realize both the beacon signal transmission function and the lighting control function, the timing of sending and receiving the lighting control signal and the timing of transmitting the beacon signal would overlap, causing delays in processing.

The first circuit unit 71a can also control the start and stop of operation of the second circuit unit 72a. For example, when there is no need to transmit a beacon signal, the operation of the second circuit unit 72a can be stopped and only the first circuit unit 71a can be operated, thereby reducing power consumption.

The first circuit unit 71a can also control the second circuit unit 72a to start and stop transmitting a beacon signal. For example, when it is not necessary to transmit a beacon signal, the first circuit unit 71a can instruct the second circuit unit 72a to stop transmitting the beacon signal, thereby reducing the amount of wireless communication.

The first circuit unit 71a includes a wireless unit 711a, a control unit 712a, and an oscillator unit 713a. The control unit 712a includes a memory unit 714a. As shown in FIG. 4(b), a space 715a is provided in the portion of the first circuit unit 71a adjacent to the wireless unit 711a.

The second circuit unit 72a includes a wireless unit 721a, a control unit 722a, and an oscillator unit 723a. The control unit 722a includes a memory unit 724a. As shown in FIG. 4(b), a space 725a is provided in the portion of the second circuit unit 72a adjacent to the wireless unit 721a.

The wireless unit 711a and the wireless unit 721a are antennas used for wireless communication, and are configured as chip antennas, for example.

The first circuit unit 71a and the second circuit unit 72a both perform wireless communication based on the Bluetooth (registered trademark) Low Energy (hereinafter referred to as "BLE") specification, but are not limited to this and may perform wireless communication based on other specifications.

Space 715a is an area where no components are mounted. If components are mounted near wireless section 711a, they will reflect radio waves and adversely affect communication performance, so providing space 715a prevents a decrease in communication performance. Space 725a is also an area where no components are mounted, just like space 715a, and just like space 715a, it prevents a decrease in communication performance.

The oscillator 713a is a clock source that generates a clock signal to be supplied to the control unit 712a, and the oscillator 723a is a clock source that generates a clock signal to be supplied to the control unit 722a. As an example, the oscillator 713a and the oscillator 723a are each composed of a crystal oscillator.

The storage unit 714a and the storage unit 724a are memory devices that store data, programs, and the like. As an example, the storage unit 714a stores a program for controlling the operation of the control unit 712a, such as a lighting control program for implementing a lighting control function.

The memory unit 724a stores programs for controlling the operation of the control unit 722a, such as a beacon signal transmission program for implementing a beacon signal transmission function, as an example.

The control unit 712a is a processor that operates based on a clock signal supplied from the oscillator unit 713a, and the processor executes a program stored in the memory unit 714a to realize functions such as a lighting control function. More specifically, the control unit 712a receives lighting control instructions related to the operation of the light source, such as turning the light source on, off, blinking, increasing the dimming rate, and decreasing the dimming rate, from the WM 7a, and outputs a control signal for performing the operation indicated by the lighting control instruction to the power supply unit 54a of the power supply device 5a via the terminal unit 75a and the socket unit 53a. The power supply unit 54a supplies power according to the received control signal to the light source unit 41a of the fixture body 4a via the electric wire 51a.

The control unit 722a is a processor that operates based on a clock signal supplied from the oscillator 723a, and realizes functions such as a beacon signal transmission function by the processor executing a program stored in the memory unit 724a.

The beacon signal includes identification information (ID) and transmission location information indicating the transmission location indicated by the beacon signal. The identification information and transmission location information are assumed to be written in advance to the storage unit 724a.

The signal line 73a is a signal line that connects the first circuit unit 71a and the second circuit unit 72a. The first circuit unit 71a and the second circuit unit 72a transmit and receive data to each other via the signal line 73a. For example, the first circuit unit 71a transmits control data via the signal line 73a, and the second circuit unit 72a operates according to the control data, thereby allowing the first circuit unit 71a to control the second circuit unit 72a.

<Terminal portion 75a>
As shown in FIG. 5, the terminal portion 75a includes a terminal 751a, a terminal 752a, a terminal 753a, a terminal 754a, and a terminal 755a.

Figure 6 shows a list of the functions (types) of terminals 751a to 755a in WM7a, along with a brief description of their uses.

Terminals 751a, 754a, and 755a are signal terminals for input/output (I/O).

The terminal 752a is a terminal for inputting power to operate the WM 7a, and accepts the input of a 3.3 volt (V) power signal supplied from the power supply unit 54a of the power supply device 5a. Note that the voltage of the power signal is not limited to 3.3 V, and may be changed according to the required specifications.

Terminal 753a is a terminal for connecting to ground, which serves as the reference for circuit operation. By connecting it to power supply unit 54a, the power supply unit 54a and WM7a share a common ground.

Here, the first circuit unit 71a that controls the lighting and the second circuit unit 72a that transmits the beacon signal require different terminals among terminals 751a to 755a. In the process of transmitting the beacon signal, the second circuit unit 72a does not need to send and receive control signals with the power supply unit 54a, and it is sufficient that the power for operating the WM 7a is supplied and that the ground is shared with the power supply unit 54a. In other words, the only terminals required in the second circuit unit 72a are terminals 752a and 753a, so as shown in FIG. 5, the second circuit unit 72a is connected only to terminals 752a and 753a, and is not connected to terminals 751a, 754a, and 755a.

On the other hand, the first circuit section 71a uses terminals 751a, 754a, and 755a to send and receive control signals for lighting control, and is therefore connected to terminals 751a, 754a, and 755a in addition to terminals 752a and 753a.

As described above, signals are transmitted through terminals 751a, 754a, and 755a only to the first circuit section 71a that requires terminals 751a, 754a, and 755a. This prevents unnecessary signals from being input to the second circuit section 72a, preventing the second circuit section 72a from malfunctioning or performing unnecessary signal processing, and reducing the processing load on the second circuit section 72a.

In FIG. 5, terminals 752a and 753a are depicted as if they are not connected to the components in the first circuit section 71a, but they are electrically connected to components in the first circuit section 71a that require a power supply, components to which a ground should be connected, etc.

As with the first circuit section 71a, the terminals 752a and 753a of the second circuit section 72a are electrically connected to components in the second circuit section 72a that require a power supply, components to which a ground should be connected, etc.

In addition, the first circuit section 71a is connected to all of the terminals 751a to 755a, and the second circuit section 72a is connected to the terminals 752a and 753a, but this is not a limitation and it is sufficient to connect the terminals so that the necessary signals can be input and output.

The terminal group (first terminal group) of terminals 751a to 755a to which the first circuit unit 71a is connected and the terminal group (second terminal group) of terminals 751a to 755a to which the second circuit unit 72a is connected may have the same or different combinations of terminals. For example, if the first circuit unit 71a uses terminal 751a for signal input/output based on the specifications of the signal to be input/output and there is no need to use terminals 754a and 755a, the first terminal group may be connected to terminals 751a to 753a, and terminals 754a and 755a may not be connected. In addition, the second circuit unit 72a may be connected to the necessary terminals of terminals 751a to 755a, not limited to terminals 752a and 753a, as the second terminal group.

As an example, WM7a has the function of 1CH (channel) control, 2CH control, and 3CH control for lighting control. Here, the channel represents the signal used to control the controlled object (power supply device 5a). The signal used differs depending on the light source adopted for the light source unit 41a to be controlled.

1CH control is a control in which, when the light source unit 41a can only dim, one signal (dimming signal) is used to instruct the power supply unit 5a to dim the light. In this case, for example, the WM 7a sends a signal to the light source unit 41a using the terminal 751a.

2CH control is a control in which, when the light source unit 41a is capable of dimming and color adjustment, a dimming signal is used to instruct the power supply unit 5a to adjust the dimming, and another signal (color adjustment signal) is used to instruct the power supply unit 5a to adjust the color. In this case, for example, the WM 7a transmits a signal to the light source unit 41a using terminals 751a and 754a.

In the 3CH control, when the light source unit 41a includes LEDs of three colors, three signals each control the light emission of the LEDs of each color. In this case, for example, the WM 7a transmits signals to the light source unit 41a using terminals 751a, 754a, and 755a.

The signal sent to the light source unit 41a is, for example, a PWM signal, but is not limited to this and any signal format capable of conveying the dimming rate to the power supply device 5a will suffice. For example, it may be a serial signal.

The WM 7a does not have any moving parts or light-emitting parts for illumination, and is less likely to break than the main body 4a and power supply 5a that constitute the lighting fixture 2a. Therefore, even if the main body 4a or power supply 5a breaks and needs to be replaced, the WM 7a can continue to be used as is.

<User terminal device 9a and lighting control device 9b>
The user terminal device 9a and the lighting control device 9b are both configured as portable information processing devices, and as an example, are smartphones having a rectangular plate-like appearance and a touch panel embedded on one surface as shown in Fig. 1. The user terminal device 9a and the lighting control device 9b have a common hardware configuration, and function as the user terminal device 9a and the lighting control device 9b by operating according to different programs.

The following mainly describes the user terminal device 9a, and the lighting control device 9b is described focusing on the differences only when necessary.

Figure 3(b) is a block diagram showing the configuration of the user terminal device 9a.

As shown in FIG. 3(b), the user terminal device 9a includes a control unit 91a, a ROM 92a, a RAM 93a, a wireless communication unit 94a, and a touch panel 95a.

The ROM 92a is composed of a flash memory or the like, and holds apps, programs, UIs, and various other data. The RAM 93a is a storage device into which the lighting control programs stored in the ROM 92a are loaded. In the case of the lighting control device 9b, the program for transmitting beacons stored in the ROM is loaded into the RAM.

The touch panel 95a is an electronic component that combines a display unit that displays images and information constituting the UI with an input unit that accepts user instructions, and functions as a user interface means. The display unit is, for example, a liquid crystal panel. The input unit is, for example, a touch pad. The touch panel 95a notifies the control unit 91a of user input. The touch panel 95a has a function of displaying a user interface (hereinafter referred to as "UI").

The control unit 91a includes a CPU (Central Processing Unit). Each function of the user terminal device 9a is realized by the control unit 91a executing a lighting control program that is loaded from the ROM 92a and stored in the RAM 93a.

The control unit 91a also determines the operation instruction (user instruction) requested by the user based on the contents of the UI displayed on the touch panel 95a and the touch and gesture input (hereinafter referred to as "user input") made by the user on the touch panel 95a, and executes processing according to the user instruction.

The wireless communication unit 94a is composed of a device that performs wireless communication. The wireless communication unit 94a performs wireless communication with the lighting fixture 2.

2. Modifications
Although an embodiment of the lighting system according to the present invention has been described above, the exemplified lighting system can be modified as follows, and it goes without saying that the present invention is not limited to the lighting system as shown in the above embodiment.

(1) Although WM7a is capable of wireless communication according to multiple communication specifications, this is not limiting, and for example, WM7a may be prepared for each different communication specification. In this case, by attaching a WM7a corresponding to the communication specification to be used to the socket portion 53a, the lighting fixture 2a becomes capable of wireless communication according to that communication specification.

(2) In the above embodiment, the identification information and the originating location information are written in advance to the storage unit 724a. However, one or both of these may be configured to be rewritable, or may be configured to be protected so that they cannot be rewritten.

When configured to be rewritable, for example, the first circuit unit 71a receives an instruction to rewrite one or both of the identification information and the transmission location information from the lighting control device 9b via wireless communication. The first circuit unit 71a then issues a rewrite instruction to the second circuit unit 72a via the signal line 73a. The second circuit unit 72a rewrites one or both of the identification information and the transmission location information in accordance with the rewrite instruction.

As a result, the second circuit unit 72a can be configured to only transmit beacon signals for wireless communication, and the processing load of the second circuit unit 72a can be allocated as much as possible to the processing of transmitting beacon signals.

(3) In the lighting device 2a, the first circuit unit 71a that controls the lighting may be configured to control the second circuit unit 72a.

For example, the first circuit unit 71a may instruct the second circuit unit 72a to start and stop executing a function via the signal line 73a. As an example, the first circuit unit 71a instructs the second circuit unit 72a to transmit and stop a beacon signal, and the second circuit unit 72a transmits a beacon signal when it receives an instruction to transmit a beacon signal, and stops transmitting the beacon signal when it receives an instruction to stop the beacon signal.

This prevents unnecessary beacon signals from being transmitted and reduces power consumption.

The first circuit unit 71a may also transmit an instruction to start operation and an instruction to stop operation to the second circuit unit 72a, and the second circuit unit 72a may start operation when it receives an instruction to start operation and stop operation when it receives an instruction to stop operation. When the second circuit unit 72a stops operation, it operates only the part that realizes the function of receiving an instruction to start operation, etc. from the first circuit unit 71a, and stops other operations. This can further reduce power consumption.

(4) In the lighting fixture 2a, the first circuit section 71a that controls the lighting may receive information necessary for the operation of the second circuit section 72a from the lighting control device 9b and transmit the information to the second circuit section 72a. Examples of the information necessary for operation include the radio wave strength of the transmitted radio waves, a communication channel, an authentication ID, a password, and other identification information.

(5) In the above embodiment, the first circuit unit 71a and the second circuit unit 72a transmit and receive data to each other via the signal line 73a, but this is not limited to the above and data may be transmitted and received to each other by other methods. For example, the first circuit unit 71a and the second circuit unit 72a may transmit and receive data to each other via wireless communication. In this case, the signal line 73a may be omitted.

(6) Any of terminals 751a, 754a, and 755a may transmit either an on signal or an off signal as an ON/OFF signal. As an example, an on signal is a high-level signal, and an off signal is a low-level signal.

When the ON/OFF signal is an ON signal, the power supply unit 5a supplies power to each color LED, and when the ON/OFF signal is an OFF signal, it does not supply power to each color LED.

When the power supply unit 5a receives a control signal from the WM 7a, it attempts to supply power to each color LED of the light source unit 41a to control the light source unit 41a in accordance with the control signal. However, due to circuit delays within the power supply unit 5a, etc., there may be variations in the timing at which power supply to each color LED begins, which may result in a period in which the light source unit 41a lights up in a color different from the desired color.

WM7a changes the ON/OFF signal to an OFF signal and sends a control signal to the power supply unit 5a. After the power supply unit 5a is able to supply power to all the LEDs, it changes the ON/OFF signal to an ON signal, thereby eliminating the period during which the light source unit 41a lights up in a color different from the desired color.

Note that the ON/OFF signal is not necessarily a required component, and if the ON/OFF signal is not required, such as when there is no delay as described above, the ON/OFF signal may not be used and the configuration of terminal 755a may be omitted.

(7) In the above embodiment, WM7a is compatible with all of 1CH, 2CH, and 3CH, but it may be compatible with one or two of 1CH, 2CH, and 3CH. By mounting WM7a, which has a control function for the channels required for controlling the power supply device 5a, in the socket unit 53a, it becomes possible to control the light source unit 41a.

(8) In the above embodiment, the WM 7a is attached to the power supply unit 5a, but this is not limiting and it is sufficient if the WM 7a is configured to be detachable from the lighting fixture 2a. For example, the WM 7a may be attachable to the fixture body 4a.

(9) Each of the functional components shown in the above embodiments may be realized as a circuit that performs its function, or may be realized by executing a lighting control program by one or more processors.

(10) The above-described embodiments and variations may be partially combined.

<3. Supplementary Information>
The configuration of a lighting system according to an embodiment of the present invention, its modifications, and effects will be described below.

(1) A lighting fixture according to one embodiment of the present invention is a lighting fixture equipped with a wireless module, which is configured to be removable and has a function for transmitting a beacon signal.

With this configuration, the lighting fixture of the present invention can provide a lighting fixture that can change the transmission position more flexibly than conventional lighting fixtures.

(2) The lighting device may also include a power supply device, and the wireless module may be detachably attached to the power supply device.

This configuration allows the wireless module to be reused as is in cases where it becomes necessary to replace the power supply unit in a lighting fixture.

(3) The wireless module may also include a first circuit unit and a second circuit unit each having a wireless communication function, the first circuit unit controlling lighting, and the second circuit unit controlling the transmission of a beacon signal.

This configuration allows lighting control and beacon signal transmission to be carried out in parallel.

(4) The first circuit unit and the second circuit unit may also be the same circuit.

This configuration allows the second circuit section to be realized by reusing the configuration of the first circuit section, thereby shortening the development time for the wireless module.

(5) The wireless module may include a plurality of terminals, and the lighting device may include a socket portion into which the wireless module is inserted to electrically connect with the plurality of terminals, the first circuit portion may be connected to a first group of the plurality of terminals, and the second circuit portion may be connected to a second group of the plurality of terminals, and the first group of terminals and the second group of terminals may have different combinations of terminals.

This configuration prevents unnecessary signal processing and reduces the processing load.

(6) The second terminal group may be a power supply terminal and a ground terminal, and the first terminal group may include the second terminal group.

This configuration allows power to be supplied to both the first and second circuit sections and provides a common ground.

(7) The first circuit unit and the second circuit unit may be connected by a signal line that does not pass through the multiple terminals, and the first circuit unit and the second circuit unit may communicate with each other via the signal line.

With this configuration, the first circuit unit can control the second circuit unit by transmitting data from the first circuit unit to the second circuit unit.

(8) The first circuit unit may write identification information to be included in the beacon signal to the second circuit unit via the signal line.

This configuration makes it possible to change the identification information included in the beacon signal using wireless communication for controlling the lighting, and allows as much of the processing load of the second circuit unit to be allocated to the transmission processing of the beacon signal as possible.

(9) Also, identification information to be included in the beacon signal may be written to the second circuit unit via the wireless communication.

With this configuration, the first circuit unit can control the second circuit unit by transmitting data from the first circuit unit to the second circuit unit via wireless communication.

(10) The second circuit unit may be capable of turning on and off the transmission of a beacon signal, and the first circuit unit may instruct the second circuit unit to turn on and off the transmission of the beacon signal via the signal line.

This configuration makes it possible to stop the transmission of unnecessary beacon signals.
