[0009] Hereinafter, the embodiments will be described with reference to the drawings. Note that the embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, component arrangement and connection forms, steps, and order of steps shown in the following embodiments are merely examples and are not intended to limit the present invention. Furthermore, among the components in the following embodiments, components that are not described in the independent claims will be described as optional components.

[0010] In addition, each drawing is a schematic diagram and is not necessarily a precise illustration. In each drawing, the same reference numerals are used for substantially the same configurations, and duplicated explanations may be omitted or simplified.

[0011] (Embodiment) [composition] First, a configuration of a lighting system according to an embodiment will be described below. Fig. 1 is a block diagram showing a functional configuration of a lighting system according to an embodiment.

[0012] The lighting system 10 shown in Fig. 1 is applied to a space (indoor space) within a facility such as a commercial facility. The lighting system 10 can provide services such as notifications to a user of a mobile terminal 40 that receives a beacon signal transmitted by a lighting fixture 20. The lighting system 10 includes a plurality of lighting fixtures 20, a setting terminal 30, and the mobile terminal 40. The plurality of lighting fixtures 20 and the setting terminal 30 constitute a lighting control system 50. The lighting system 10 and the lighting control system 50 only need to include at least one lighting fixture 20.

[0013] First, the lighting fixture 20 will be described. FIG. 2 is a diagram showing an example of the installation of the lighting fixture 20. As shown in FIG. 2, the lighting fixture 20 is an indirect lighting fixture that is installed on a structure provided on a wall of an indoor space and illuminates the wall and the ceiling. Hereinafter, the main emission direction of the light (illumination light) emitted by the lighting fixture 20 is described as a specific direction. The specific direction can be considered to be, for example, a direction parallel to the optical axis, a direction in which the light intensity is strongest, or a direction along the center line of the light irradiation range, and in the example of FIG. 2, it is a vertical upward direction. When the lighting fixture 20 is an indirect lighting fixture, the specific direction is, for example, a direction from the lighting fixture 20 toward the wall or ceiling of the indoor space.

[0014] The specific embodiment of lighting device 20 is not particularly limited. Lighting device 20 may be a normal lighting device such as a base light, instead of an indirect lighting device. Lighting device 20 specifically includes lighting unit 21, communication unit 22, wireless communication unit 23, control unit 24, and storage unit 25.

[0015] The illumination unit 21 emits illumination light in the specific direction using power supplied from a system power supply. The illumination light emitted by the illumination unit 21 is, for example, white light. The illumination unit 21 is realized by, for example, an LED (Light Emitting Diode) element, but may be realized by other light emitting elements such as a semiconductor laser, an organic EL (Electro-Luminescence), or an inorganic EL.

[0016] The communication unit 22 is a communication circuit that enables the lighting fixture 20 to communicate with other lighting fixtures 20 and the setting terminal 30 via a local communication network. The communication unit 22 may be a wireless communication circuit that performs wireless communication, or a wired communication circuit that performs wired communication. Examples of communication protocols for wireless communication include, but are not limited to, Wi-Fi (registered trademark), BLE (Bluetooth (registered trademark) Low Energy), and Zigbee (registered trademark). Examples of communication standards for wired communication include, but are not limited to, Ethernet (registered trademark) and power line communication.

[0017] The wireless communication unit 23 periodically transmits a beacon signal (sometimes called an advertisement signal, etc.). Specifically, the wireless communication unit 23 is a wireless communication circuit that transmits a beacon signal according to a communication protocol (communication standard) such as BLE. The wireless communication unit 23 includes an antenna 23a. The antenna 23a is, for example, a pattern antenna.

[0018] The reception range in which the mobile terminal 40 can receive the beacon signal emitted by the wireless communication unit 23 is illustrated in FIG. 2 as a schematic ellipse with a broken line. The reception range has a shape that is longer on the side opposite to the specific direction of the lighting device 20 than on the side on the specific direction of the lighting device 20, based on the position of the lighting device 20. This allows the lighting device 20 to transmit the beacon signal to the mobile terminal 40 located in the indoor space while emitting illumination light to the wall or ceiling side. The reception range having such a shape may be realized by designing the shape of the pattern antenna, or may be realized by adjusting the circuit constant of the wireless communication circuit. The reception range having the above shape may also be realized by arranging a dielectric material or the like around the wireless communication unit 23 in the lighting device 20. The reception range may be realized by combining two or more of these methods. The reception range can also be widened or narrowed by adjusting the transmission power of the beacon signal.

[0019] When communication unit 22 is a wireless communication circuit, communication unit 22 and wireless communication unit 23 can be realized by a common wireless communication circuit (such as a communication module or a communication chip). In this case, antenna 23a that emits a beacon signal is also used to receive a lighting control signal for controlling the light emission of lighting fixture 20. The lighting control signal is transmitted by setting terminal 30 or another lighting controller (not shown).

[0020] The control unit 24 processes information on the control of the illumination unit 21 and the communication unit 22, and the control of the wireless communication unit 23 (beacon signal). The control unit 24 is realized by, for example, a microcomputer, but may also be realized by a processor or a dedicated circuit. The functions of the control unit 24 are realized by hardware such as a microcomputer or a processor constituting the control unit 24 executing a computer program (software) stored in the storage unit 25.

[0021] The storage unit 25 is a storage device that stores information necessary for the above information processing. The information stored in the storage unit 25 includes computer programs executed by the control unit 24. The storage unit 25 is realized by, for example, a semiconductor memory.

[0022] Next, the setting terminal 30 will be described. The setting terminal 30 is an information terminal operated by a setting person to change settings related to the beacon signals of the lighting fixtures 20. The setting terminal 30 is, for example, a dedicated remote controller for the lighting control system 50, but may also be realized by installing a predetermined application program on a general-purpose information terminal. The general-purpose information terminal is, for example, a personal computer, a smartphone, or a tablet terminal. Specifically, the setting terminal 30 includes an operation receiving unit 31, a display unit 32, a communication unit 33, a control unit 34, and a storage unit 35.

[0023] The operation reception unit 31 receives operations from a settler. Specifically, the operation reception unit 31 is realized by a mouse, a keyboard, a touch panel, or the like.

[0024] The display unit 32 is a display on which an image visually recognized by the settler is displayed, and is realized by a display panel such as a liquid crystal panel or an organic EL panel.

[0025] The communication unit 33 is a communication circuit that enables the setting terminal 30 to communicate through the local communication network with each of the plurality of lighting fixtures 20. The communication unit 33 may be a wireless communication circuit that performs wireless communication, or a wired communication circuit that performs wired communication.

[0026] The control unit 34 processes information related to changing the settings of the beacon signal. The control unit 34 is realized by, for example, a microcomputer, but may also be realized by a processor or a dedicated circuit. The functions of the control unit 34 are realized by hardware such as a microcomputer or a processor constituting the control unit 34 executing a computer program (software) stored in the storage unit 35.

[0027] The storage unit 35 is a storage device that stores information necessary for the above information processing. The information stored in the storage unit 35 includes a computer program executed by the control unit 34. The storage unit 35 is realized by, for example, a semiconductor memory.

[0028] Next, mobile terminal 40 will be described. Mobile terminal 40 is a portable information terminal carried by a user visiting a facility where lighting fixture 20 is installed (such as the commercial facility in FIG. 2), and is an example of a receiver for a beacon signal emitted by lighting fixture 20. Mobile terminal 40 is, for example, a smartphone, a tablet terminal, or a personal digital assistant (PDA). Mobile terminal 40 specifically includes an operation acceptance unit 41, a display unit 42, a receiving unit 43, a control unit 44, and a storage unit 45.

[0029] The operation reception unit 41 receives operations from a user. Specifically, the operation reception unit 41 is realized by a touch panel or the like.

[0030] The display unit 42 is a display on which an image visually recognized by a user is displayed, and is realized by, for example, a display panel such as a liquid crystal panel or an organic EL panel.

[0031] Receiving unit 43 receives a beacon signal emitted by lighting fixture 20. Specifically, receiving unit 43 is a wireless communication circuit that receives a beacon signal in accordance with a communication protocol (communication standard) such as BLE.

[0032] The control unit 44 performs information processing for notifying the user, etc., based on the beacon signal received by the receiving unit 43. The control unit 44 is realized, for example, by a microcomputer, but may also be realized by a processor or a dedicated circuit. The functions of the control unit 44 are realized by hardware such as a microcomputer or a processor constituting the control unit 44 executing a computer program (software) stored in the storage unit 45.

[0033] The storage unit 45 is a storage device that stores information necessary for the above information processing. The information stored in the storage unit 45 includes computer programs executed by the control unit 44. The computer programs are, for example, so-called application programs (hereinafter also simply referred to as apps) that are installed in advance in the storage unit 45 by a user. The storage unit 45 is realized, for example, by a semiconductor memory or the like.

[0034] [Beacon signal data format] In the lighting system 10, a setting person can change the transmission frequency of a beacon signal (the time interval at which a beacon signal is transmitted) by operating the setting terminal 30. Fig. 3 is a diagram showing an example of a data format of a beacon signal. As shown in Fig. 3, data format A of a beacon signal includes, as components, header information, a service ID, a beacon ID, and additional information.

[0035] The header information is identification information defined by a communication protocol, and includes an individual address of the lighting fixture 20 (the device that transmits the beacon signal).

[0036] The service ID is information for identifying a service provided by a beacon signal, and is an example of a second ID. In other words, the service ID is an identification ID defined by a business operator that transmits the beacon signal.

[0037] The beacon ID is information for identifying lighting fixture 20 (the device that transmits the beacon signal) and is an example of a first ID. When lighting fixture 20 is installed in a commercial facility, by appropriately setting the beacon ID in accordance with a predetermined rule, mobile terminal 40 can identify the building, floor, store, etc. in which lighting fixture 20 that transmits the beacon signal is installed, based on the received beacon signal.

[0038] The additional information is information for adding more detailed information to the beacon signal. Examples of the additional information include an identifier or a time stamp for strengthening security. Note that depending on the data format, the additional information may not be included.

[0039] More specific examples of beacon IDs and service IDs are as follows: In iBeacon (registered trademark), Major and Minor correspond to beacon IDs, and UUID corresponds to service ID.

[0040] [Beacon signal setting operation example] As described above, in the lighting system 10, a setting person can change the transmission frequency of a beacon signal by operating the setting terminal 30. Hereinafter, a first example of such a setting operation of a beacon signal will be described. Fig. 4 is a sequence diagram of an example of the setting operation of a beacon signal.

[0041] The setting person performs a predetermined first operation for displaying a selection screen for lighting fixtures 20, and operation reception unit 31 receives such a first operation (S11). When the first operation is received, control unit 34 displays a selection screen for lighting fixtures 20 on display unit 32 (S12). FIG. 5 is a diagram showing an example of the selection screen for lighting fixtures 20. Each of the lighting fixtures 20 is associated with location information (coordinates) of the lighting fixture 20 within the commercial facility (map) and is registered in advance in setting terminal 30. In the selection screen of FIG. 5, a top view (map) of the arrangement of the lighting fixtures 20 is displayed, and each of the rectangles arranged in a matrix represents a lighting fixture 20. In the selection screen, the lighting fixtures 20 may be displayed as a list using characters.

[0042] When the selection screen for lighting fixtures 20 in Fig. 5 is displayed, the person making the setting performs a predetermined second operation for selecting a lighting fixture 20, and operation receiving unit 31 receives such second operation (S13). When the second operation is received, control unit 34 displays on display unit 32 a setting screen for a beacon signal to be transmitted by lighting fixture 20 selected in step S13 (S14). Fig. 6 shows an example of the setting screen for a beacon signal.

[0043] As shown in FIG. 6, the beacon signal setting screen allows the user to set (input) one of multiple pre-registered data formats, the transmission state (on or off), the transmission frequency, the service ID, the beacon ID, and additional information.

[0044] After making the necessary settings, the person making the settings makes a predetermined third operation for transmitting setting information indicating the settings made in step S14 to lighting device 20, and operation receiving unit 31 receives such a third operation (S15). When the third operation is received, controller 34 uses communication unit 33 to transmit the setting information to lighting device 20 selected in step S13 (S16).

[0045] The third operation may be performed multiple times corresponding to multiple lighting devices 20, or may be performed only once after setting beacon signals for multiple lighting devices 20. In other words, the setting information may be transmitted to each of the multiple lighting devices 20 in a single operation.

[0046] Communication unit 22 of lighting fixture 20 receives the setting information. Control unit 24 stores the received setting information in memory unit 25 (S17), and thereafter controls wireless communication unit 23 in accordance with the stored setting information. In other words, control unit 24 can determine (change) the frequency of transmission of a beacon signal transmitted by wireless communication unit 23, etc., based on the setting information.

[0047] [Example of mobile device operation] Next, an example of the operation of mobile terminal 40 when multiple types of beacon signals having different data formats are transmitted in a time-division manner by lighting fixtures 20 in a commercial facility will be described. Fig. 7 is a sequence diagram of an example of the operation of mobile terminal 40.

[0048] Each of the lighting fixtures 20 transmits a plurality of types of beacon signals having different data formats at a set transmission frequency (time interval) (S21).

[0049] When a user carrying mobile terminal 40 enters a commercial facility and approaches multiple lighting fixtures 20, receiver 43 of mobile terminal 40 receives a beacon signal, and controller 44 displays notification information on display 42 in response to the received beacon signal (S22). Fig. 8 is a diagram showing an example of how notification information is displayed.

[0050] For example, if the service ID and beacon ID in the data format of beacon A are linked to notification information A regarding a coupon that can be used at clothing store A, the control unit 44 displays notification information A on the display unit 42 upon receiving a beacon signal corresponding to beacon A.

[0051] In addition, if the service ID and beacon ID in the data format of beacon B are linked to notification information B regarding an event being held at commercial facility B, the control unit 44 displays notification information B on the display unit 42 when it receives a beacon signal corresponding to beacon B.

[0052] In this way, the mobile terminal 40 can provide a plurality of types of notifications corresponding to a plurality of types of beacon signals.

[0053] Furthermore, the mobile terminal 40 may perform notification based on a beacon signal corresponding to beacon B while an application using a beacon signal corresponding to beacon A is being executed. Fig. 9 is a diagram showing an example in which notification is performed based on a beacon signal corresponding to beacon B while an application using a beacon signal corresponding to beacon A is being executed.

[0054] 9, the control unit 44 of the mobile terminal 40 is executing an application that measures the current location of the mobile terminal 40 by using the received signal strength of a beacon signal corresponding to beacon A and displays the location on a map. When the receiving unit 43 receives a beacon signal corresponding to beacon B while such an application is being executed, the control unit 44 displays notification information on the map.

[0055] For example, if the service ID and beacon ID in the data format of beacon B are linked to notification information B regarding a coupon that can be used at grocery store B, control unit 44 displays notification information B at the location of grocery store B on the map.

[0056] In this manner, the mobile terminal 40 can perform notification based on the beacon signal corresponding to the beacon B while an application that uses the beacon signal corresponding to the beacon A is being executed.

[0057] Furthermore, mobile terminal 40 may selectively execute one of the apps installed in storage unit 45 in response to the received beacon signal. For example, upon receiving a beacon signal corresponding to beacon A, control unit 44 may execute the corresponding app A, and upon receiving a beacon signal corresponding to beacon B, may execute the corresponding app B.

[0058] [Variations] As described above with reference to FIG. 2, the reception range in which mobile terminal 40 can receive a beacon signal emitted by wireless communication unit 23 of lighting device 20 has a shape that is longer in the opposite direction of lighting device 20 than in the specific direction of lighting device 20. However, the reception range may have a circular (spherical) shape centered on the position of lighting device 20. FIG. 10 is a diagram showing a modified example of the reception range in which mobile terminal 40 can receive a beacon signal. In this way, the reception range may have a shape with less bias centered on the position of lighting device 20. In other words, the beacon signal does not have to be directional.

[0059] 2 and 10, wireless communication unit 23 of lighting device 20 only needs to emit a beacon signal at least in the direction opposite to the specific direction. In this way, when lighting device 20 is an indirect lighting device, the beacon signal can reach mobile device 40 located in the indoor space.

[0060] Note that the opposite direction to the specific direction is not a strict definition. For example, as shown in Fig. 2, when a direction that is 180° different from the specific direction in a side view (direction that is completely opposite) is set as a reference direction, the angle between the reference direction and the opposite direction may be within a range of ±α. α is, for example, 45°, but may also be 30°, 15°, or 5°.

[0061] The advantages of using lighting fixtures 20 as beacon transmitters as in the above embodiment include the following advantages. Since lighting fixtures 20 are installed comprehensively at approximately equal intervals on the ceiling, when lighting fixtures 20 are used as beacon transmitters, there is an advantage that the beacon transmitters are automatically arranged comprehensively. Furthermore, since lighting fixtures 20 are installed on the ceiling where there are few obstacles, there is an advantage that there are few obstacles for the beacon signal (radio waves) when lighting fixture 20 is used as a beacon transmitter. Furthermore, when a dedicated beacon transmitter separate from lighting fixture 20 is installed, power supply to the beacon transmitter (wiring of a power line) becomes an issue, but when lighting fixture 20 is used as a beacon transmitter, there is an advantage that there is no need to consider power supply.
