  Subsequently, the operation of the present embodiment will be described with reference to the flowcharts of FIGS. FIG. 5 is a flowchart for explaining an example of the operation of the area controller according to the embodiment. FIG. 6 is a flowchart for explaining an example of the operation of the lighting device according to the embodiment.

  The area controller 2 determines whether or not to operate each lighting device 21 connected via the communication line CC in the emergency mode based on a system control signal input via the communication line CA (step in FIG. 5). S1).

  Then, when a system control signal for operating each lighting device 21 in the emergency mode is input (S1: Yes), the area controller 2 performs communication line CC based on the smoke detection information included in the system control signal. It generates and outputs an illumination control signal for controlling the illumination state of the light emitting modules 41 and 42 of each illumination device 21 connected via the illumination mode to the emergency mode illumination state (step S2 in FIG. 5).

  Specifically, when a system control signal for operating each lighting device 21 in the emergency mode is input, the area controller 2 detects, for example, a smoke amount equal to or more than 0 and equal to or less than the threshold value THA (<THB). The lighting device 21 corresponding to the installation position of the smoke detector 33 that generates the W light and the B light from the lighting device 21 corresponding to the installation position of the smoke detector 33 and detects a smoke amount larger than the threshold value THA and equal to or smaller than the threshold value THB. To generate a W light and a G light from the lighting device 21 corresponding to the installation position of the smoke detector 33 that has detected the amount of smoke larger than the threshold value THB. Output.

  In addition, when a system control signal for operating each lighting device 21 in the normal mode is input (S1: No), the area controller 2 connects each of the lighting devices 21 via the communication line CC based on a user's instruction. An illumination control signal for controlling the illumination state of the light emitting modules 41 and 42 of the illumination device 21 to the illumination state in the normal mode is generated and output (step S3 in FIG. 5).

  Specifically, when a system control signal for operating each lighting device 21 in the normal mode is input, the area controller 2 is input, for example, in response to an operation of the operation instruction unit 11 or the wall switch by the user. Based on the instruction signal, a lighting control signal for controlling the amount of W light generated from each lighting device 21 connected via the communication line CC is generated and output.

  When a system control signal for operating each lighting device 21 in the normal mode is input, the area controller 2 controls the light amount of the W light, and controls the R light, the G light, By simultaneously controlling the amount of light of at least one color of the B light, the effect of each lighting device 21 connected via the communication line CC may be provided. Further, when a system control signal for operating each of the lighting devices 21 in the normal mode is input, the area controller 2 determines, for example, a determination result related to the presence or absence of a person within the detection range of the human sensor 22. Accordingly, the amount of W light generated from each lighting device 21 connected via the communication line CC may be controlled.

  On the other hand, the light source control unit 55 of the lighting apparatus 21 determines whether or not each light emitting element emits light in the emergency mode based on the lighting control signal input via the communication line CC and the signal input unit 53 (FIG. 6). Step S11).

  Then, when an illumination control signal for controlling the illumination state of the light emitting modules 41 and 42 to the illumination state in the emergency mode is input (S11: Yes), the light source control unit 55 performs the processing in step S12 in FIG. Perform the operation. Further, when an illumination control signal for controlling the illumination state of the light emitting modules 41 and 42 to the illumination state of the normal mode is input (S11: No), the light source control unit 55 performs the processing of step S14 in FIG. Perform the operation.

  The light source control unit 55 determines whether the power supply from the commercial power supply CPS is stopped (Step S12 in FIG. 6).

  When obtaining the determination result that the power supply from the commercial power supply CPS is stopped (S12: Yes), the light source control unit 55 starts the power supply from the battery 54 to each unit of the lighting device 21. After that (step S13 in FIG. 6), the operation of step S14 in FIG. 6 described later is performed. In addition, when the light source control unit 55 obtains the determination result that the power supply from the commercial power supply CPS is not stopped (S12: No), the light source control unit 55 performs the operation of step S14 in FIG.

  The light source control unit 55 generates a light emission control signal for controlling the light emission state of the light emitting elements 41a, 41b, and 42a to 42c based on the illumination control signal input via the communication line CC and the signal input unit 53. Output to the drive circuits 51a, 51b, 52a, 52b and 52c, respectively (step S14 in FIG. 6).

  Specifically, the light source control unit 55 receives, for example, an illumination control signal for controlling the illumination state of the light emitting modules 41 and 42 to the emergency mode illumination state, and outputs the commercial power CPS in step S12 of FIG. When the determination result that the power supply from is not stopped is obtained, the light emission for simultaneously emitting the light emitting elements 41a and 41b and any one of the light emitting elements 42a to 42c is performed. Generate and output a control signal. The light source control unit 55 receives, for example, an illumination control signal for controlling the illumination state of the light emitting modules 41 and 42 to the emergency mode illumination state, and supplies power from the battery 54 in step S13 of FIG. Is started, a light emission control signal is generated to cause any one of the light emitting elements 42a to 42c to emit light while causing the light emitting elements 41a and 41b to emit light with a light amount equal to or less than a predetermined value. Output. Further, for example, when an illumination control signal for controlling the illumination state of the light emitting modules 41 and 42 to the illumination state of the normal mode is input, the light source control unit 55 causes the light emitting elements 41a and 41b to emit light. A light emission control signal is generated and output.

  In other words, in the emergency mode, for example, when the smoke detector 33 installed closest to the lighting device 21 detects a smoke amount of 0 or more and the threshold value THA or less, the light-emitting elements 41a and 41b And 42c are simultaneously generated and output. Further, in the emergency mode, for example, when the smoke detector 33 installed in the vicinity of the lighting device 21 detects a smoke amount larger than the threshold value THA and equal to or smaller than the threshold value THB in the emergency mode, the light emitting element 41a , 41b, and 42b are simultaneously generated and output. In the emergency mode, for example, when the smoke detector 33 of the lighting device 21 detects a smoke amount larger than the threshold value THB in the emergency mode, the light emitting elements 41a, 41b, and 42a emit light simultaneously. And outputs a light emission control signal for the same.

  When the light source control unit 55 causes the light emitting elements 41a and 41b to emit light with a light amount equal to or less than a predetermined value in step S14 of FIG. 6, for example, the light source control unit 55 emits light with 30% or less of the maximum light amount of the light emitting elements 41a and 41b. Control may be performed, or control may be performed such that each of the light emitting elements 41a and 41b blinks. According to the control of the light source control unit 55, the amount of power consumed according to the operation of the lighting device 21 in the emergency mode can be reduced. Even when the power supply from the CPS is stopped, the operation time of the lighting device 21 by the power supplied from the battery 54 can be extended as much as possible.

  Here, according to the operations of the area controller 2 and the light source control unit 55 as described above, for example, as shown in FIG. 7, four passages V1 to V4 and two passages orthogonal to the passages V1 to V4 When a fire occurs on a floor having H1 and H2, an emergency exit E1 communicating from the passage V4 to the outside, and an emergency exit E2 communicating from the passage H2 to the outside, the lighting state of each lighting device 21 is as shown in FIG. It is controlled to the state. FIG. 7 is a schematic diagram illustrating an example of a floor on which the lighting device according to the embodiment is installed. FIG. 8 is a schematic diagram illustrating an example of an illumination state of each illumination device when a fire occurs on the floor illustrated in FIG. 7.

  Specifically, when a fire occurs on the floor as shown in FIG. 7, according to the operation of the area controller 2 and the light source control unit 55, for example, as shown in FIG. W light and R light are emitted from each lighting device 21 near the installed smoke sensor 33, and W light and R light are emitted from each lighting device 21 near each smoke sensor 33 installed in the area adjacent to the fire source. Light and G light are emitted, and W light and B light are emitted from each lighting device 21 near each smoke detector 33 installed in an area distant from the fire source. Therefore, according to the present embodiment, when a fire occurs on the floor as shown in FIG. 7, for example, an evacuation route to the emergency exit E1 via the passage V3 or the passage V4 relatively close to the fire source is dangerous. It is possible to intuitively notify the victim of the fact and that the evacuation route to the emergency exit E2 via the passage V1 or V2 which is relatively far from the fire source is safe.

  By the way, for example, in a building in which the number of emergency lights 31 and guide lights 32 is a lower limit or a number close to the lower limit specified by law, the intervals between the emergency lights 31 and guide lights 32 are increased. Because of the tendency, when a fire occurs in the building, it may be very difficult for the victim to evacuate while visually checking the emergency light 31 and / or the guide light 32.

  On the other hand, according to the present embodiment, the emergency light 31 and the guide light 32 are installed in the building at an installation interval smaller than the installation interval (or the number of installations is larger than the emergency light 31 and the guide light 32). By changing the lighting state of the lighting device 21 in accordance with the amount of smoke detected by each smoke detector 33, a safe evacuation route in the event of a fire in the building can be reliably provided to the victim. I can let you know. That is, according to the present embodiment, it is possible to reliably notify the victim of a safe evacuation route when a disaster occurs in the building.

  According to the present embodiment, for example, when a fire occurs in a building, the user operating the operation instruction unit 11 stores the smoke detection information output from the disaster prevention system 3 and the smoke detection information in the storage unit 12. Each area controller 2 or each lighting device 21 may be manually controlled based on the map information.

  Further, according to the present embodiment, for example, when one or more heat sensors are connected to the disaster prevention system 3 via the communication line CD, the amount of heat detected by each heat sensor is used for each heat sensor. Is output from the disaster prevention system 3, and the control unit 13 generates a system control signal corresponding to a determination result of whether or not a fire has occurred based on the heat detection information. Then, the generated system control signal may be output to each area controller 2.

  Further, according to the present embodiment, for example, when one or more cameras are connected to the disaster prevention system 3 via the communication line CD, an image captured by each camera is output from the disaster prevention system 3, and The control unit 13 generates a system control signal corresponding to a determination result of whether or not a fire has occurred based on the image, and the generated system control signal is output to each area controller 2. Is also good.

  Further, according to the present embodiment, for example, when the same map information stored in the storage unit 12 is shared in the disaster prevention system 3, the same control as the system control signal generated by the control unit 13 is performed. A signal may be generated in the disaster prevention system 3, and the generated control signal may be directly output to each area controller 2 without passing through the console 1.

  According to the present embodiment, for example, when the same map information as that stored in the storage unit 12 is shared in the disaster prevention system 3, the same control as the illumination control signal generated by the area controller 2 is performed. A signal may be generated in the disaster prevention system 3, and the generated control signal may be directly output to each lighting device 21 without passing through the console 1 and the area controller 2.

  According to the present embodiment, for example, when the smoke detector 33 is provided in the lighting device 21 and the smoke detection signal from the smoke detector 33 is input to the signal input unit 53, the light source control is performed. The unit 55 may control the light emitting state of each light emitting element based on the smoke detection signal.
