Detailed Description

The present embodiment will be described below with reference to the drawings. The same or equivalent parts or components are denoted by the same reference numerals in the drawings.

The illumination system according to the present embodiment will be described in detail below with reference to the drawings. Further, the embodiments described below show general or specific examples. The numerical values, shapes, materials, components, arrangement positions and connection manners of the components, steps, order of the steps, and the like shown in the following embodiments are examples, and are not intended to limit the present disclosure. Further, among the components in the following embodiments, components not described in the independent claims representing the highest concept will be described as arbitrary components. The dimensional ratios in the drawings are exaggerated for convenience of explanation and may be different from actual ratios.

As shown in fig. 1, the lighting system 1 of the present embodiment includes a plurality of lighting apparatuses 10, …, a plurality of beacon scanners 20, … as communication apparatuses, a portable apparatus 30, an inquiry unit 40 as an input unit, and a management server 50.

The respective lighting apparatuses 10 are dispersedly provided in a space 60 such as an office. As shown in fig. 2, each lighting apparatus 10 includes a lighting light source 12, a notification light source 13, and a controller 14 in a cylindrical housing 11, for example.

The illumination Light source 12 and the notification Light source 13 can be configured using, for example, an LED (Light Emitting Diode). The illumination light source 12 and the notification light source 13 can be turned on in accordance with the pattern and the emission color instructed by the controller 14. In the present embodiment, the illumination light source 12 can illuminate the illumination region 15 below the cover 11. The notification light source 13 can illuminate an illumination region 16 around the cover 11.

As shown in fig. 3, a light shielding member 17 may be attached to the outside of the cover 11. By attaching the light-shielding member 17, the illumination region 15 of the illumination light source 12 and the illumination region 16 of the notification light source 13 can be separated.

The controller 14 of fig. 2 receives a control signal from the lighting controller 70 arranged in the space 60, and the control signal from the lighting controller 70 arranged in the space 60 is received by the controller 14 in the form of a light signal via the conversion unit 71 in the space 60. Then, the controller 14 causes the illumination light source 12 and the notification light source 13 to light in a light emission manner and a light emission color corresponding to the pattern indicated by the received control signal, respectively.

In the present embodiment, for example, as shown in fig. 4, when no person is present on a chair 80 provided in the space 60 below the illumination area 15, the controller 14 turns off the illumination light source 12. For example, as shown in fig. 5, when a person 90 is present on the chair 80 in the illumination area 15, the controller 14 causes the illumination light source 12 to light up in a predetermined illumination color.

In the present embodiment, when the person 90 is present on the chair 80 in the illumination area 15 of the illumination light source 12, the controller 14 causes the notification light source 13 to light in a sitting color such as orange. In the present embodiment, as shown in fig. 4, when the person 90 is not present on the chair 80 in the illumination area 15, the controller 14 causes the notification light source 13 to be lit in an off-color such as green.

In the present embodiment, as shown in fig. 5, when the person 90 present on the chair 80 in the illumination area 15 is a person 90 who has been queried from the later-described query unit 40, the controller 14 causes the notification light source 13 to blink with a notification color such as pink, for example.

The controller 14 in fig. 2 can turn on and off the illumination light source 12 and the notification light source 13 of each of the illumination devices 10 in the light emission manner and the light emission color indicated by the control signal from the illumination controller 70 in fig. 1.

The lighting controller 70 can change the content of the control signal for each lighting apparatus 10 in accordance with the control mode of each lighting apparatus 10 notified to the lighting controller 70 from the management server 50, which will be described later, via the network 100. The network 100 can be formed of, for example, ethernet (registered trademark).

The lighting system and the emission color of the lighting light source 12 and the notification light source 13, which are instructed by the lighting controller 70 with a control signal according to the control mode notified from the management server 50, can be arbitrarily set by a user, not shown, in the lighting controller 70. This setting can be performed on, for example, a console screen (not shown) displayed on the tablet terminal 110. The console screen can be displayed on the tablet terminal 110 by performing wireless communication between the lighting controller 70 and the tablet terminal 110.

Further, the wireless communication of the lighting controller 70 with the tablet terminal 110 can use, for example, wiFi (registered trademark) or the like for communication.

A plurality of the beacon scanners 20 are provided in a distributed manner in the space 60, for example, on the ceiling. The arrangement of the beacon scanners 20 on the ceiling may be, for example, a grid.

Each beacon scanner 20 is connected to the network 100 via a Switching Hub (Switching Hub) 120. Each beacon scanner 20 can operate, for example, in accordance with a power supply signal supplied from the network 100 side in addition to the control signal.

The portable device 30 of fig. 1 can be used to detect the presence of a person 90 within the space 60. Thus, the portable devices 30 are held by the persons 90 present in the space 60. The portable device 30 can be configured by, for example, a dedicated beacon 31 and a smartphone 32 that can wirelessly communicate with the beacon scanner 20. A tablet terminal may also be used instead of the smartphone 32. As shown in fig. 6, each portable device 30 transmits a beacon signal including identification information of the portable device 30 at a fixed cycle (S13).

The identification information of the portable device 30 is information for identifying the portable device 30, which is the transmission source of the beacon signal received by each beacon scanner 20. The identification information of the portable device 30 may be identification information of the portable device 30 or identification information of the person 90 who carries the portable device 30. The identification information of the portable device 30 can be, for example, a management number or a Media Access Control (MAC) address of the portable device 30.

Note that the beacon scanner 20 is dedicated to reception in the present embodiment, but may have a transmission/reception function. When the transmission/reception function is provided, for example, each beacon scanner 20 may transmit an inquiry signal at a fixed cycle (S11), and the mobile device 30 in the communication area 21 that has received the inquiry signal may transmit the beacon signal (S13). The transmission of the inquiry signal by each beacon scanner 20 can be performed based on a control signal periodically supplied from the management server 50 via the network 100, for example.

In addition, when the person 90 is not present on the chair 80 present in the communication area 21 of the beacon scanner 20 as shown in fig. 4, the beacon scanner 20 does not receive the beacon signal from the portable device 30 in the communication area 21. In this case, the illumination area 15 of the illumination light source 12 of the illumination device 10 illuminating the communication area 21 in which the beacon scanner 20 does not receive the beacon signal becomes a non-reaction area in which the beacon signal is not received in the corresponding communication area 21.

On the other hand, when a person 90 is present on a chair 80 present in the communication area 21 of the beacon scanner 20 as shown in fig. 5, the beacon scanner 20 receives a beacon signal from the portable device 30 in the communication area 21. In this case, the illumination area 15 of the illumination light source 12 of the illumination device 10 illuminating the communication area 21 in which the beacon scanner 20 receives the beacon signal becomes a reaction area in which the corresponding communication area 21 receives the beacon signal.

The beacon signal transmitted from the portable device 30 in fig. 1 is received by the beacon scanner 20 in which the portable device 30 exists in the communication area 21. The identification information of the mobile device 30 indicated by the beacon signal received by each beacon scanner 20 and the reception intensity of the beacon signal are collected at a fixed cycle, and are notified as management information to the management server 50 (described later) via the network 100 as shown in fig. 6 (S15). The management information notified by the beacon scanner 20 may include identification information of the beacon scanner 20 itself.

The wireless communication between the beacon scanner 20 and the mobile device 30 in fig. 1 can be performed using, for example, communication such as Bluetooth (registered trademark), specific low-power wireless using a frequency in the 920MHz band, zigbee (registered trademark), wiFi (registered trademark), or the like. As the dedicated beacon 31, for example, a Bluetooth (registered trademark) beacon (BLE beacon) using a frequency in a 2.4GHz band or a 5GHz band can be used.

The inquiring unit 40 can be used, for example, for an inquiry by a visitor as to whether or not a specific person 90 to be accessed is present in the space 60. The inquiry unit 40 as an input unit can be constituted by, for example, a stationary personal computer 41 and a smartphone 42.

The personal computer 41 may be disposed, for example, near an entrance of the space 60, in an elevator hall (not shown) of a floor where the space 60 is located, or the like. The smartphone 42 can use, for example, a smartphone held by a visitor of the space 60. A tablet terminal may also be used instead of the smartphone 42. The inquiry unit 40 is connected to the network 100 via an access point (not shown) using WiFi (registered trademark), for example.

By inputting identification information of a specific person 90 to be accessed on a console screen, not shown, displayed on the display unit, the inquiring unit 40 can inquire of the management server 50 via the network 100 whether the person 90 is present in the space 60.

The management server 50 is connected to each beacon scanner 20, the query unit 40, and the lighting controller 70 via a network 100. The management server 50 receives management information from each beacon scanner 20.

The management server 50 holds a table in which the identification information of the beacon scanner 20 is associated with the arrangement in the space 60, a table in which the identification information of the portable device 30 is associated with the person 90 holding the portable device 30, and the like.

Therefore, the management server 50 can determine whether or not the person 90 is present in the communication area 21 of each beacon scanner 20 based on the presence or absence and the content of the information input from each beacon scanner 20, and can recognize the person 90 present in the communication area 21. Further, the management server 50 can determine whether or not there is a beacon scanner 20 in the communication area 21 in which the specific person 90 matching the identification information input from the inquiry unit 40 exists.

When the management information having the same identification information of the mobile device 30 is received from two or more beacon scanners 20, the management server 50 can use the management information from the beacon scanner 20 having the highest reception intensity of the beacon signal, for example, for the determination of the presence or absence of the person 90.

In addition, the management server 50 has information on the arrangement of each lighting device 10 and each beacon scanner 20 in the space 60. Thus, the management server 50 can specify the lighting apparatus 10 including the communication area 21 where the person 90 exists in the lighting area 15 of the lighting light source 12.

Further, the management server 50 can display the result of the inquiry from the inquiry unit 40 on, for example, a display 62 connected to the network 100. The display 62 can be provided, for example, near the entrance of the space 60 or on a wall 61 of an elevator hall or the like.

For example, when the management server 50 determines that the specific person 90 is present, the result screen in which the mark 63 indicating the position where the specific person 90 is present is arranged on the floor map 64 of the space 60 as shown in fig. 7 can be displayed on the display 62.

Also, the management server 50 notifies the lighting controller 70 of the control pattern corresponding to the result of the above-described determination and recognition as the control pattern of the corresponding lighting apparatus 10 as shown in fig. 6 (S17).

The illumination controller 70 outputs a control signal to each of the illumination devices 10, which causes the illumination-use light source 12 and the notification-use light source 13 to light up in the light emission manner and the light emission color set from the tablet terminal 110 for the control mode notified from the management server 50, respectively (S19).

The input operation of the inquiry unit 40 to the management server 50 can be performed through the network 100 from, for example, a management computer 130 of fig. 1 operated by an administrator, not shown.

In the illumination system 1 of the present embodiment described above, for example, as shown in fig. 5, when a person 90 is present on a chair 80 provided in an illumination area 15 of the illumination light source 12 of the illumination device 10, the notification light source 13 of the illumination device 10 is lit in the sitting color.

In the lighting apparatus 10 that illuminates the chair 80, which is the subject of the access and is being used by the specific person 90 who has been inquired of the location from the inquiry unit 40, with the lighting light source 12, the lighting manner and lighting color of the notification light source 13 are switched from lighting in the sitting color to blinking in the notification color. Therefore, even after leaving the display 62, the inquired visitor 140 can reach the location of the specific person 90 as shown in fig. 9 by using the lighting device 10 in which the illumination area 16 of the notification light source 13 is illuminated with the notification color blinking illumination as a mark.

When the arriving visitor 140 moves away from the location of the chair 80 together with the person 90 to be visited, the illumination light source 12 that illuminates the chair 80 is turned off, and the lighting mode and the lighting color of the notification light source 13 are switched from blinking with the notification color to lighting with the non-presence color. Therefore, the person 90 present in the space 60 can easily recognize the position of the chair 80 that is vacant in the space 60, by using the lighting apparatus 10 that does not illuminate with color as a mark, the illumination region 16 of the notification light source 13.

That is, if the position is a good line of sight, the result of the management server 50 detecting the person 90 present in the space 60 can be appropriately notified by the lighting manner and lighting color of the illumination region 16 of the notification light source 13 of the illumination device 10 that can be seen from any position in the space 60.

In the above-described embodiment, the case where the lighting apparatus 10 is a ceiling lamp is taken as an example and explained. However, for example, as shown in (a) to (c) of fig. 11, lighting devices 150 to 170 as a wall lamp, a floor lamp, or a table lamp may be used instead of the lighting device 10.

The lighting fixture 150 as a wall lamp in fig. 11 (a) is a lighting fixture in which the housing 11 of the lighting fixture 10 in fig. 2 is attached to a wall 61 of the space 60 or the like by a bracket 65. The

160 and 170 shown in fig. 11 (b) and (c) as floor lamps and table lamps are lighting devices in which the cover 11 of the lighting device 10 shown in fig. 2 is suspended from the upper ends of the

brackets

161 and 171.

The lighting fixture 150 as a wall lamp can be used by being attached to the wall 61 above the chair 80 shown in fig. 4 and 5, for example. The lighting device 160 as a floor lamp can be used by being disposed upright on the side of the chair 80 in fig. 4 and 5, for example. The lighting device 170 as a table lamp can be used by being installed on, for example, a table 180 (see fig. 8 to 10) disposed in the closest vicinity of the chair 80.
