The luminaire 3 includes a light source 30, a lighting circuit 31 that lights the light source 30, and a microprocessor or logic IC that controls lighting of the light source 30 by controlling the lighting circuit 31 (hereinafter referred to as a microprocessor or the like). A control unit 32, a storage unit 33 including a ROM, a flash memory, or an EEPROM in which logical addresses are stored in advance, and a communication I / F (Interface) unit 34 that communicates with the gateway device 4 are provided.

  The light source 30 can be composed of an LED, a fluorescent lamp, a high-intensity discharge lamp, a light bulb, or the like. The control unit 32 controls the communication I / F unit 34 to transmit the logical address of the own device to the gateway device 4 when connected to the lighting device 3. The control unit 34 controls the lighting of the light source 30 based on the lighting control signal transmitted from the gateway device 4 and received via the communication I / F unit 34. The communication I / F unit 34 is configured by a two-wire serial communication circuit compliant with RS485 or the like, and a serial communication cable is used as the communication line 2 in accordance therewith.

  The gateway machine 4 is connected to a plurality of lighting fixtures 3, detects a communication I / F unit 40 that communicates with them, and a connection between the communication I / F unit 40 and the lighting fixture 3, and receives a logical address from the lighting fixture 3. The computer 41 communicates with the computer device 6, the control unit 41 configured by a microprocessor or the like to be acquired, the storage unit 42 configured by a storage medium such as a flash memory or EEPROM in which the logical address acquired by the control unit 41 is stored. And a computer communication I / F unit 43.

  The communication I / F unit 40 and the computer communication I / F unit 43 have the same type of communication circuit configuration as the communication I / F unit 34 of the lighting fixture 3. The control unit 41 refers to the storage unit 42, designates the logical addresses of the lighting fixtures 3 one by one as the transmission destination of the lighting control signal, and sequentially turns on or off the lighting fixtures 3 (lighting control unit). Further, the control unit 41 creates a correspondence table between the logical address of the lighting fixture 3 that has been turned on or off and the physical address that is set by the computer device 6 for the lighting fixture 3, and stores the correspondence table in the storage unit 42 is stored.

  The computer device 6 is a control composed of an image signal input unit 60 to which a captured image signal of the lighting fixture 3 by the imaging device 5 is input, and a microprocessor that displays a captured image on the monitor 61 based on the captured image signal. Unit 62, a setting unit 63 for a user to set a physical address for each of the lighting fixtures 3 on a captured image (hereinafter referred to as a display image) displayed on the monitor 61, the above-described captured image and its A storage unit 64 that stores the physical address of the lighting fixture 3 set on the captured image, and a communication I / F unit 65 that communicates with the gateway machine are provided.

  The control unit 62 detects a change area of the display image caused by lighting or extinguishing of the luminaire 3 (detection section), and sets a physical address set for the luminaire 3 in the change area as a communication I / F. The data is transmitted to the gateway machine 4 using the unit 65. The setting unit 63 includes a mouse, a light pen, or a touch panel that can indicate an arbitrary position on the display image, and a keyboard that can input a physical address in association with the specified position. Various instructions of the gateway machine 4 and imaging control of the imaging device 5 can be performed by operating the setting unit 63. The communication I / F unit 65 has the same type of communication circuit configuration as that of the computer communication I / F unit 43.

  Next, the physical address setting operation to the lighting fixture 3 in the lighting system 1 will be described with reference to FIGS. 4 and 5 in addition to the above-described FIGS. First, the computer device 6 instructs the imaging device 5 to image the lighting fixture 3 based on the operation of the setting unit 63 by the user, and the imaging device 5 images the entire lighting fixture 3 disposed on the ceiling. It is desirable that all the lighting fixtures 3 are lit during imaging. The monitor 61 displays the captured image.

  The setting unit 63 is operated by the user. Next, the lighting fixtures 3 shown in the display image on the monitor 61 are individually indicated, and a physical address is set in association with the indicated position. For example, when an arbitrary position is designated on the display image, the physical address setting can automatically display a text input frame in association with the designated position.

The control unit 62 controls the display of the monitor 61 so that the indicated position and the physical address are superimposed on the captured image. FIG. 4 shows an example of the displayed captured image G1. In the figure, indicated positions are plotted, and numerical values are assigned as physical addresses in the order of arrangement of the lighting fixtures 3. The control unit 62 stores the captured image G1, the coordinate information (X _i , Y _i ) (i = 1 to 9 in FIG. 4) of the designated position, and the physical address associated therewith in the storage unit 64.

  Then, the setting unit 63 is operated again by the user, and the control unit 62 instructs the gateway machine 4 to turn off all the lighting devices 3 via the communication I / F unit 65. The control unit 41 of the gateway machine 4 receives the instruction via the communication I / F unit 40, transmits a turn-off control signal to all the lighting fixtures 3, and turns them off. The control unit 62 of the computer device 6 instructs the gateway device 4 to turn off and instructs the imaging device 5 to perform imaging. The imaging device 5 images all the lighting devices 3 that have been turned off, and the control unit 62 stores this captured image in the storage unit 64 as a reference captured image.

  After acquiring the above-described reference captured image, the control unit 62 instructs the gateway machine 4 to turn on the lighting fixtures 3 one by one for a predetermined time. Based on this instruction, the gateway machine 4 turns on the lighting fixtures 3 one by one in the ascending order of the logical addresses. The lighting fixtures 3 may be lit in descending order of logical addresses or randomly. The control unit 62 instructs the imaging device 5 to image the lighting fixture 3 each time the lighting fixtures 3 are turned on one by one. FIGS. 5A to 5C show a captured image G1 at that time, and as an example, when the lighting fixtures 3 (see FIG. 2 described above) having logical addresses LA of 001 to 003 are sequentially turned on, the images are captured. An image G1 is shown.

  Further, each time the lighting fixtures 3 are turned on one by one, the control unit 62 compares the captured image with the above-described reference captured image (image when all the lighting fixtures 3 are turned off), and changes in the captured image. An area, that is, its change position and range is detected as coordinate information. When the captured image is, for example, a monochrome image, an area where the difference in brightness is equal to or greater than a predetermined value during the comparison is detected as the change area. Then, the control unit 62 refers to the storage unit 64, selects the coordinate information of the indicated position in the change area, and acquires physical address information associated therewith. This physical address is # 7 in FIG. 5 (a), # 5 in FIG. 5 (b), and # 9 in FIG. 5 (c). The physical address information is sent from the control unit 62 to the gateway device 4 via the communication I / F unit 65.

  The control unit 41 of the gateway machine 4 receives the physical address information described above via the communication I / F unit 40, and stores the physical address and the logical address of the lighting fixture 3 that is lit at that time. Refer to and associate. Such association is made for all the lighting fixtures 3, and a correspondence table is created and stored in the storage unit 42. After creating the correspondence table, the computer device 6 can be detached from the gateway machine 4 together with the imaging device 5.

  In the present embodiment, each physical address of the lighting fixture 3 set by the setting unit 63 of the computer device 6 is associated with the logical address preset in each lighting fixture 3 by the gateway machine 4. Then, when the user designates a physical address by the setting unit 63, the gateway machine 4 selects a logical address corresponding to the physical address, and performs lighting control using the lighting fixture 3 in which the logical address is set as a control target. Therefore, the control target can be specified by specifying the physical address of the lighting fixture 3. For this reason, when the physical address is set according to the positional relationship such as the arrangement of the lighting fixtures 3, for example, the position of the lighting fixture 3 and the physical address can be easily linked, and are set regardless of the position of the lighting fixture 3. Compared to the case of the logical address, it becomes easier to specify the lighting fixture 3 to be controlled. Since the setting of the physical address can be performed while looking at the monitor 61 of the computer device 6, the setting work is easy.

  In addition, when the lighting system 1 is installed on each floor of a building having a plurality of floors and the lighting fixtures 3 are installed in the same manner on each floor, the lighting fixtures 3 are imaged on one floor, and on the captured image When the physical address of the lighting fixture 3 is set, the captured image and the physical address are stored in the storage unit. Therefore, the physical address setting work can be omitted by using them on other floors.
