DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[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. Fig. 1 is a block diagram showing a functional configuration of a lighting system according to an embodiment. Fig. 2 is a diagram showing an example of a space to which a beacon communication system according to an embodiment is applied.

[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 emitted 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. The lighting fixture 20 is a spotlight or the like that is installed on a wall or ceiling of an indoor space and illuminates the indoor space. The form of the lighting fixture 20 is not particularly limited, and may be a ceiling light, a downlight, a base light, or the like. The lighting fixture 20 does not need to be fixed to a wall or ceiling, and may be a portable lighting fixture such as a stand light. The lighting fixture 20 specifically includes a lighting unit 21, a communication unit 22, a wireless communication unit 23, a control unit 24, and a storage unit 25.

[0014] The lighting unit 21 emits illumination light in a specific direction using power supplied from a system power supply. In the example of FIG. 2, the lighting fixture 20 is used to light up exhibited (displayed) products, and the specific direction is a direction from the lighting fixture 20 toward the exhibited products. The specific direction means a main emission direction of light (illumination light) emitted by the lighting fixture 20, and 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. The illumination light emitted by the lighting unit 21 is, for example, white light. The lighting 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.

[0015] 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.

[0016] The wireless communication unit 23 periodically emits a beacon signal (sometimes called an advertisement signal, etc.). Specifically, the wireless communication unit 23 is a wireless communication circuit that emits a beacon signal according to a communication protocol (communication standard) such as BLE. The wireless communication unit 23 includes a plurality of antennas 23a. The antennas 23a are, for example, pattern antennas.

[0017] The wireless communication unit 23 emits a directional beacon signal. If the direction in which the beacon signal has directivity is defined as the transmission direction, the transmission direction is a direction different from the specific direction in which the illumination light is emitted. Specifically, the directivity of the beacon signal is adjusted so that the beacon signal reaches only the area ahead of the transmission direction and hardly reaches other areas.

[0018] In this way, lighting fixture 20 can emit a beacon signal having directionality in a direction different from the specific direction in which the illumination light is emitted, thereby illuminating the product (shelf) and emitting a beacon signal toward mobile terminal 40 carried by a user positioned in the aisle in front of the product.

[0019] Moreover, the wireless communication unit 23 (control unit 24) can change the transmission direction by selectively using the multiple antennas 23a to transmit a beacon signal. In the example of FIG. 2, the wireless communication unit 23 can transmit a beacon signal in a first transmission direction using the first antenna 23a among the multiple antennas 23a, and the reception range in which the mobile terminal 40 can receive the beacon signal is the reception range A on the right side of FIG. 2. Moreover, the wireless communication unit 23 can transmit a beacon signal in a second transmission direction using the second antenna 23a among the multiple antennas 23a, and the reception range in which the mobile terminal 40 can receive the beacon signal is the reception range B on the left side of FIG. 2. The wireless communication unit 23 can also transmit a beacon signal using the first antenna 23a and the second antenna 23a at the same time. The transmission direction of the beacon signal is changed depending on, for example, the installation location and use of the lighting fixture 20.

[0020] Possible methods for making the beacon signal directional and limiting the reception range include at least one of the following: changing the design of the pattern antenna shape, adjusting the circuit constant of the wireless communication circuit, and arranging a dielectric material around the wireless communication unit 23 in the lighting fixture 20. The reception range of the beacon signal can also be changed by adjusting the transmission power of the beacon signal.

[0021] 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).

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] [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.

[0037] 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).

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] [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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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).

[0047] 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.

[0048] 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 transmission frequency of a beacon signal emitted by wireless communication unit 23, etc., based on the setting information.

[0049] [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.

[0050] 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).

[0051] 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.

[0052] 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.

[0053] 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.

[0054] In this way, the mobile terminal 40 can provide a plurality of types of notifications corresponding to a plurality of types of beacon signals.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] In this way, 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.

[0059] 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.

[0060] [Variations] In the above embodiment, a means for switching between multiple antennas 23a is used as a means for changing the transmission direction of a beacon signal. However, the means for changing the transmission direction of a beacon signal is not limited to a means for switching between multiple antennas 23a. For example, lighting device 20 (wireless communication unit 23) may include one antenna 23a and a mechanism for changing the orientation (posture) of one antenna 23a, and the transmission direction may be changed by the mechanism. This mechanism may be a mechanism that can manually change the orientation of antenna 23a, or may be an electric actuator that can electrically change the orientation of antenna 23a.

[0061] Furthermore, lighting device 20 may include a slot around antenna 23a into which a dielectric is inserted, and the transmission direction may be changed depending on whether or not a dielectric is inserted into the slot. For example, lighting device 20 may include one antenna 23a and multiple slots arranged to surround one antenna 23a, and the transmission direction may be changed by inserting a dielectric into some of the multiple slots.

[0062] Furthermore, lighting fixture 20 may include a means for changing the specific direction in which lighting fixture 20 emits illumination light, in addition to the means for changing the transmission direction of the beacon signal. For example, lighting fixture 20 may include a movable mechanism that connects a mounting structure for mounting lighting fixture 20 to a wall or ceiling and the main body (lamp) of lighting fixture 20. This improves the degree of freedom in combining the transmission direction of the beacon signal and the specific direction in which illumination light is emitted. For example, lighting fixture 20 can be installed in an easy-to-install location, and then the specific direction in which illumination light is emitted and the transmission direction of the beacon signal can each be changed (adjusted), improving usability.

[0063] 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.
