Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram illustrating a configuration of an illuminance control system 1 according to the present embodiment. The illuminance control system 1 is connected to a plurality of lamps 10-N (lamp 10-1, lamp 10-2, lamp 10-3, lamp 10-4, lamp 10-5,...) And these lamps 10. The illuminance control device 20 is provided. Here, since several lamp 10-N is the same structure, when it is not necessary to distinguish and explain in particular, it demonstrates as the lamp 10. FIG.

  Here, with reference to drawings, the space which performs the illumination control by the illumination control system 1 of this embodiment is demonstrated. FIG. 2 is a diagram illustrating an example of an office room that performs illuminance control by the illuminance control system 1. A plurality of desks and chairs are installed in the office room, and the points where the desks are installed are designated as points P1, P2, P3,..., P32. A plurality of lamps 10 are installed on the ceiling in the office room. Let the lamp 10 installed in the ceiling be L1, L2, L3, ..., L36. Here, the points P1 to P14 and the points P19 to P32 are private seats, and the points P15 to P18 are shared seats.

  The lamp 10 is a dimmable lighting device installed on a ceiling or wall in an office room. For the lamp 10, for example, an LED lighting device, a fluorescent lamp, an incandescent lamp, or the like can be applied. For example, a device that performs dimming of a fluorescent lamp by an inverter base can be applied. The dimming may be adjusted by changing the brightness in stages, or may be adjusted by changing the brightness continuously without steps. Here, it is assumed that the lamp 10 includes a control unit that performs dimming by changing the brightness of lighting in response to an input of a lighting command including a lighting rate indicating the degree of dimming.

  The illuminance control device 20 is a computer device that performs dimming control of a plurality of lamps 10 installed in an office space that is an illuminance control target, and is connected to the plurality of lamps 10. The illuminance control device 20 includes an illuminance data storage unit 21, an illuminance distribution data storage unit 22, a lighting rate data storage unit 23, a lighting request input unit 24, a readjustment rate calculation unit 25, and a dimming control unit 26. It has.

  The illuminance data storage unit 21 stores in advance illuminance data in which a required illuminance that is an illuminance desired by the user is associated with each of a plurality of determined users. FIG. 3 is a diagram illustrating a data example of illuminance data stored in the illuminance data storage unit 21. In the illuminance data, the required illuminance (unit: lx (lux)) at the individual seat and the required illuminance (unit: lx (lux)) at the shared seat are stored in association with the user ID. The user ID is identification information for identifying a user who uses the office space subject to illumination control. The personal seat is the preferred illuminance (required illuminance) at the corresponding user's personal seat. The shared seat is a favorite illuminance (required illuminance) in the shared seat of the corresponding user. As described above, the illuminance data storage unit 21 stores the required illuminance for each of the individual seat and the common seat for each user. In addition to this, for example, the required illuminance according to the time zone may be stored in association with the illuminance control according to the time zone.

  In the illuminance distribution data storage unit 22, the illuminance at each point when the lamp is turned on for each of a plurality of points (P 1 to P 32) determined in a space illuminated by the plurality of lamps is stored in the plurality of lamps (L 1 Illuminance distribution data associated with each L36) is stored in advance. FIG. 4 is a diagram illustrating a data example of illuminance distribution data stored in the illuminance distribution data storage unit 22. Here, the dimming is associated with a column indicating lamp ID that is lamp identification information for identifying a lamp and a row indicating point ID that is point identification information for identifying a predetermined point in the office space. The illuminance at each point when a possible lamp is lit at the maximum (100%) lighting rate is stored. The unit of illuminance is lx (lux). For example, when the lamp 10 whose lamp ID is L23 is turned on, the illuminance at the point P21 is 100 lux, and the illuminance at the point P22 is 410 lux. Such illuminance may be a value measured in advance or a value calculated by simulation. Here, when there is a movable partition in the office room, for example, the illuminance distribution data storage unit 22 stores in advance the illuminance distribution data for both when the partition is open and when the partition is closed. In addition, reading may be performed according to the situation.

  In the lighting rate data storage unit 23, for each of a plurality of points (P1 to P32), lamp identification information (lamp ID) for identifying the lamp that is lit to illuminate the spot with a predetermined illuminance and the adjustment of the lamp. Lighting rate data associated with a lighting rate indicating the degree of light is stored. FIG. 5 is a diagram illustrating a data example of lighting rate data stored in the lighting rate data storage unit 23. In the figure, lighting rate data at the points P21 and P22 are shown. For example, in order to illuminate the point P21 with an illuminance of 300 lux, it is shown that the lamp L29 is lit at a lighting rate of 70%. Similarly, in order to illuminate the point P21 with an illuminance of 700 lux, the lamp L29 is turned on at a lighting rate of 100%, the lamp L30 is turned on at a lighting rate of 100%, and the lamp L23 is turned on at a lighting rate of 10%. ing. Although only the lighting rate data for individual seats is shown here, similar lighting rate data can be prepared and stored in advance for shared seats.

  The lighting request input unit 24 receives an input of a lighting request indicating any one of the plurality of points (P1 to P32) and any one of the plurality of users. A lighting request | requirement is information which requests | requires that any one of the designated points | pieces is illuminated with the required illumination intensity corresponding to the designated user. Specifically, for example, for each user, an IC (Integrated Circuit) card storing a user ID for identifying the user is issued, and the user carries the IC card. On the other hand, at each point in the office room, an IC card reader in which the point ID of the point is stored in advance is installed and connected to the illuminance control device 20 via the network. When the user goes to any point in the office room, the IC card reader installed at that point reads the IC card. The IC card reader transmits a lighting request including the user ID read from the IC card and the spot ID stored in advance in its own storage area to the illuminance control device 20. The lighting request input unit 24 receives the lighting request input by receiving the lighting request transmitted from the IC card reader.

  When a plurality of lighting requests are input to the lighting request input unit 24, the readjustment rate calculation unit 25 reads a plurality of requested illuminances corresponding to the user indicated by each of the plurality of lighting requests from the illuminance data storage unit 21, and reads The plurality of lighting rate data for illuminating the point indicated by each of the plurality of lighting requests by the plurality of requested illuminances is read from the lighting rate data storage unit 23, and the same lamp ID is included in the plurality of read lighting rate data. If included, the illuminance distribution data stored in the illuminance distribution data storage unit 22 indicates a readjustment rate at which the illuminance at each of the plurality of points included in the plurality of lighting requests is within a predetermined range of the required illuminance. Calculate based on

  Specifically, for example, the lighting request input unit 24 has a first lighting request in which the user ID is 1 and the spot ID is P21, and a second lighting request in which the user ID is 2 and the spot ID is P22. Are received. In this case, the readjustment rate calculation unit 25 reads the illuminance data D1 corresponding to the user ID “1” and the illuminance data D2 corresponding to the user ID “2” from the illuminance data storage unit 21. Here, the required illuminance of any individual seat is 700 (lux). The readjustment rate calculation unit 25 reads, from the lighting rate data storage unit 23, a lamp ID and a lighting rate T1 for illuminating the point P21 with illuminance 700 (lux). Similarly, a lamp ID and a lighting rate T2 for illuminating the point P22 with an illuminance of 700 (lux) are read out.

  As shown in FIG. 5, in order to illuminate the point P21 with an illuminance of 700 (lux), the lamp L29 is turned on at a lighting rate T1 of 100%, the lamp L30 is 100%, and the lamp L23 is 10%. On the other hand, in order to illuminate the point P22 with an illuminance of 700 (lux), the lamp L23 is turned on at a lighting rate T2 of 100%, the lamp L24 is 100%, and the lamp L29 is 10%. That is, in order to set the illuminance at both points to at least 700 (lux) or more, all of the lamp L23, the lamp L24, the lamp L29, and the lamp L30 are turned on at a lighting rate of 100%. When the lamp 10 is turned on in this way, the illuminance I1 at the point P21 and the illuminance I2 at the point P22 are the total values shown in FIG. Here, the direct illuminance when a plurality of lamps are turned on is obtained by adding the individual illuminance of each lamp by the point-by-point method. Similarly, indirect light can be added. That is, the illuminance I1 at the point P21 is 100 + 80 + 420 + 270 = 870 (lux). The illuminance I2 at the point P22 is 410 + 260 + 150 + 110 = 930 (lux).

  Based on the illuminance calculated in this way, the readjustment rate calculation unit 25 obtains the value of (requested illuminance ÷ calculated illuminance) as the readjustment rate R. For example, the readjustment rate R1 at the point P21 is (700 ÷ 870) = 0.8. The readjustment rate R2 at the point P22 is (700 ÷ 930) = 0.75. Therefore, the readjustment rate calculation unit 25 obtains a value obtained by multiplying the illuminance I1 and the illuminance I2 by the readjustment rate R1 and the readjustment rate R2. However, at the point P21, the lamp L29 and the lamp L30 are multiplied by the readjustment rate R1, and at the point P22, the lamp L23 and the lamp L24 are multiplied by the readjustment rate R2. The illuminance I1 ′ when the lamp 10 is turned on at such a lighting rate based on the readjustment rate is 100 × 0.75 + 80 × 0.75 + 420 × 0.8 + 270 × 0.8 = 687 (lux) at the point P21. is there. Similarly, the illuminance I2 ′ at the point P22 is 410 × 0.75 + 260 × 0.75 + 150 × 0.8 + 110 × 0.8 = 710 (lux). Thereby, the illuminance at both points is close to the user's required illuminance 700 (lux).

  The dimming control unit 26 transmits a lighting command to the lamp 10 in response to the lighting request input to the lighting request input unit 24. In addition, the dimming control unit 26 receives a plurality of lighting requests input to the lighting request input unit 24, and if the same lamp ID is included in the input lighting request, the dimming control unit 26 performs the readjustment rate calculation unit 25. The lamp 10 is turned on at a lighting rate based on the calculated readjustment rate R. Specifically, the dimming control unit 26 calculates a lighting rate based on the readjustment rate R calculated by the readjustment rate calculation unit 25 for each lamp 10, and a lighting command for lighting at the calculated lighting rate Is transmitted to the control unit of the lamp 10. The lamp 10 lights the lamp 10 at a specified lighting rate in accordance with the lighting command transmitted from the dimming control unit 26.

  Moreover, the light control part 26 is the largest among the several request | requirement illumination intensity corresponding to the user according to a lighting request, when the several lighting request | requirement input into the said lighting request input part is a lighting request | requirement with respect to the same point. A lighting command for lighting the lamp according to the illuminance is transmitted to the lamp 10. That is, when a plurality of users are seated at the same point, a lighting command is transmitted in accordance with a user who prefers brighter illumination among the plurality of users.

Next, an operation example of the illuminance control system 1 according to the present embodiment will be described. FIG. 6 is a flowchart illustrating an operation example in which the illuminance control device 20 dimmes the plurality of lamps 10.
First, when a user with a user ID of 1 sits at a point P21, the user's IC card is held over an IC card reader installed on the desk at the point P21. The IC card reader transmits to the illuminance control device 20 a lighting request including the user ID read from the user's IC card and the spot ID previously stored in the storage area of the IC card reader. The illuminance control device 20 receives the lighting request transmitted from the IC card reader (step S1).

  The readjustment rate calculation unit 25 of the illuminance control device 20 reads the required illuminance D1 (700 (lux)) corresponding to the user ID “1” indicated by the lighting request from the illuminance data storage unit 21 (step S2). Further, the readjustment rate calculation unit 25 reads the lighting rate T1 corresponding to the required illuminance D1 (700 (lux)) at the point P21 indicated by the lighting request from the lighting rate data storage unit 23 (step S3). The dimming control unit 26 transmits a lighting command based on the lighting rate T <b> 1 read by the readjustment rate calculating unit 25 to the lamp 10. Here, the readjustment rate calculation unit 25 is a lighting command for lighting at a lighting rate of 100% for the lamp L29, a lighting rate of 100% for the lamp L30, and a lighting rate of 10% for the lamp L23. Is transmitted (step S4). The lamp 10 that has received the lighting command lights up according to the received lighting command. Thus, FIG. 7 shows the relationship between the required illuminance D1, the lighting rate T1, and the illuminance I1 when the lighting request is for one user for one point. The lamp 10 indicated by the symbol a lights up with the lighting rate T1 corresponding to the required illuminance D1. At this time, the illuminance I1 on the desk of the desk indicated by symbol b matches the required illuminance D1.

  Returning to FIG. 6, when the user whose user ID is 2 is seated at the point P22, the user holds his IC card over the IC card reader installed on the desk at the point P22. The IC card reader transmits to the illuminance control device 20 a lighting request including the user ID read from the user's IC card and the spot ID previously stored in the storage area of the IC card reader. The illuminance control device 20 receives the lighting request transmitted from the IC card reader (step S5).

  The readjustment rate calculation unit 25 of the illuminance control device 20 reads out the required illuminance D2 (700 (lux)) corresponding to the user ID “2” indicated by the lighting request from the illuminance data storage unit 21 (step S6). Further, the readjustment rate calculation unit 25 reads the lighting rate T2 corresponding to the required illuminance D2 (700 (lux)) at the point P22 indicated by the lighting request from the lighting rate data storage unit 23 (step S7). Here, the readjustment rate calculation unit 25 determines whether or not the lighting rate T1 and the lighting rate T2 correspond to the same lamp ID. If the lighting rate T1 and the lighting rate T2 do not correspond to the same lamp ID, the dimming control unit 26 transmits a lighting command to the lamp 10 in the same manner as in step S4 and ends the process. On the other hand, if the lighting rate T1 and the lighting rate T2 correspond to the same lamp ID, the readjustment rate calculation unit 25 performs readjustment rate calculation processing.

  In the readjustment rate calculation process, the readjustment rate calculation unit 25 calculates the illuminances I1 and I2 based on the lighting rate T1 and the lighting rate T2 as described above (step S8). Then, the readjustment rate R1 (= D1 / I1) and the readjustment rate R2 (= D2 / I2) at each point are calculated (step S9). Here, the readjustment rate calculation unit 25 has the illuminances I1 ′ and I2 ′ based on the calculated readjustment rates R1 and R2 within a predetermined range from the required illuminances D1 and D2 (for example, within plus or minus 50 lux). It is determined whether or not there is. If the calculated illuminance is not within a predetermined range from the required illuminance, the readjustment rate calculation unit 25 may perform the readjustment rate calculation process in step S9 again. On the other hand, if the calculated illuminance is within a predetermined range from the required illuminance, the dimming control unit 26 uses the lighting rate obtained by multiplying the lighting rate T1 and the lighting rate T2 by the readjustment rate R1 and the readjustment rate R2. The lighting command is transmitted to the lamp 10. The lamp 10 that has received the lighting command adjusts light according to the received lighting command. FIG. 8 shows the relationship among the required illuminances D1 and D2, the lighting rates T1 and T2, and the illuminances I1 and I2 when the lighting request is for two users for two points. The illuminance on the desk of the desk indicated by reference signs b1 and b2 is the illuminance at which the lamp 10 indicated by reference sign a1 is turned on based on the lighting rate T1 corresponding to the required illuminance D1, and the illuminance indicated by reference sign a2 is determined according to the required illuminance D1. It becomes a total value with the illuminance which turned on based on the lighting rate T1.

  In the above, an example is shown in which a user with a user ID of 1 and a user with a user ID of 2 sit next to each other. Next, a user with a user ID of 1 and a user with a user ID of 3 5 shows an example of calculating the readjustment rate R in the case of seating next to each other. As shown in FIG. 3, the user whose user ID is 3 has a required illuminance D3 at a personal seat of 500 (lux). In the following, an example in which a user with a user ID of 3 is seated at a point P21 and a user with a user ID of 1 is seated at a point P22 is shown. In this case, as shown in FIG. 5, the lighting rate of the lamp L30 when the point P21 is illuminated with the required illuminance D3 (500 lux) is 30%, and the point P22 is illuminated with the required illuminance D1 (700 lux). The lighting rate of the lamp L30 is 0%. At this time, the illuminance I3 at the point P21 is 100 × 1 + 80 × 1 + 420 × 1 + 270 × 0.3 = 681 (lux). On the other hand, the illuminance I1 at the point P22 is 410 × 1 + 260 × 1 + 150 × 1 + 110 × 0.3 = 853 (lux). Based on this, when the readjustment rate R3 at the point P21 is obtained, the readjustment rate R3 = D3 / I3 = 500/681 = 0.73. Similarly, when the readjustment rate R1 at the point P22 is obtained, the readjustment rate R1 = D1 / I1 = 700/853 = 0.82.

  When the illuminance I3 ′ at the point P21 is obtained based on such a readjustment rate, 100 × 1 × 0.82 + 80 × 1 × 0.82 + 420 × 1 × 0.73 + 270 × 0.3 × 0.73 = 513 ( Lux). On the other hand, when the illuminance I1 ′ at the point P22 is obtained, it is 410 × 1 × 0.82 + 260 × 1 × 0.82 + 150 × 1 × 0.73 + 110 × 0.3 × 0.73 = 682 (lux). Thus, the illuminance I3 ′ is 513 (lux), and the required illuminance D3 is 500 (lux). Further, since the illuminance I1 ′ is 682 (lux) and the required illuminance D1 is 700 (lux), each can be controlled to an illuminance close to the required illuminance.

  In the present embodiment, the lighting request input unit 24 installs an IC card reader for each point and receives a lighting request transmitted from an IC card reader that has read the user's IC card. A button for transmitting a lighting request may be provided for each point, and the lighting request may be transmitted by pressing the button. In addition, a lighting request may be transmitted by detecting a user's seating using a position information system including an RFID (Radio Frequency IDentification) and an antenna.
