(Embodiment)
Hereinafter, embodiments will be described with reference to FIGS.

[Configuration of lighting system]
FIG. 1 is a configuration diagram of a lighting system according to an embodiment.

  As shown in FIG. 1, the lighting system 1 includes a schedule controller 10, a lighting controller 20, and a plurality of lighting fixtures 30. In the lighting system 1, the schedule controller 10 controls the lighting fixture 30 via the lighting controller 20.

  The schedule controller 10 instructs the lighting controller 20 to change the lighting control method of the lighting fixture 30 and the parameters of the light characteristics according to a predetermined schedule. That is, the schedule controller 10 can cause the lighting controller 20 to perform an operation according to a predetermined schedule. Information for causing the lighting controller 20 to operate in accordance with a predetermined schedule is stored in, for example, a storage unit (not shown) included in the schedule controller 10. The lighting control method will be described in detail with reference to FIG. The schedule controller 10 communicates with the lighting controller 20 wirelessly, for example, but may communicate with a wire.

  The schedule controller 10 divides a predetermined time into a predetermined time for a fade instruction for changing the light characteristic parameter of the lighting fixture 30 toward the target value in a stepwise manner with respect to the lighting controller 20. Do it every time. Specifically, the schedule controller 10 fades in steps toward the target dimming rate and the target color temperature using the dimming rate and the color temperature as target values as parameters of the light characteristics of the luminaire 30 in stages. An instruction is given to the illumination controller 20 for each predetermined time for a predetermined time. The fade instruction will be described in detail later with reference to FIG. The operation of the schedule controller 10 will be described in detail with reference to FIG.

  The lighting controller 20 controls the lighting fixture 30 in accordance with an instruction from the schedule controller 10. The illumination controller 20 includes a sensor 21 that performs detection according to the lighting control method. The lighting controller 20 changes the parameter of the light characteristic of the lighting fixture 30 according to the fade instruction and the detection result of the sensor 21 selectively. Specifically, the lighting controller 20 changes the dimming rate as a parameter of the light characteristics of the lighting fixture 30 according to both the fade instruction and the detection result of the sensor 21. Further, the lighting controller 20 changes the color temperature as a parameter of the light characteristics of the lighting fixture 30 in accordance with the fade instruction. That is, the dimming rate of the luminaire 30 is changed according to the fade instruction and the detection result of the sensor 21, and the color temperature of the luminaire 30 is changed according to the fade instruction.

  The lighting controller 20 changes the parameter of the light characteristic of the lighting fixture 30 stepwise toward the target value for each division time for a predetermined time. Specifically, the lighting controller 20 sets the dimming rate and the color temperature as the parameters of the light characteristics of the lighting fixture 30, and sets the target dimming rate and the target as the target values step by step for each predetermined period of time. Change toward the color temperature. The operation of the illumination controller 20 will be described in detail with reference to FIG.

  The sensor 21 is a sensor that detects the presence or absence of a person or brightness according to a lighting control method in an area illuminated by each of the lighting fixtures 30. For example, the lighting controller 20 may include a sensor 21 for each region illuminated by the lighting fixtures 30, or may include a sensor 21 for each region illuminated by a predetermined number of lighting fixtures 30 of the lighting fixtures 30. Good. Moreover, the illumination controller 20 may be provided with the sensor 21 which detects all the area | regions which each of the lighting fixture 30 illuminates, for example.

  The sensor 21 is, for example, an image sensor. The sensor 21 or the lighting controller 20 has, for example, an image in a state where a person is present, an image in a state where no person is present, an image where a person is moving, and various brightnesses in an area illuminated by the lighting fixture 30. Images are stored. The sensor 21 compares the current image in the area illuminated by the lighting fixture 30 photographed by the sensor 21 with the stored image, thereby detecting the presence of a person and the brightness. The sensor 21 may be any sensor that can detect the presence or absence of a person and the brightness, and may be, for example, a sensor that combines a human sensor such as an infrared sensor and an illuminance sensor.

  The lighting fixture 30 is a lighting fixture capable of dimming and toning the light to be output. The lighting fixture 30 is dimmed by changing the dimming rate by adjusting the light output of the light source included in the lighting fixture 30 to the lighting controller 20. Moreover, the lighting fixture 30 is provided with a plurality of light sources having different color temperatures composed of, for example, blue LEDs and yellow phosphors, and the lighting fixture 30 outputs the light by adjusting the ratio of the light output of each light source to the lighting controller 20. Tone by changing the color temperature of the light. In addition, the lighting fixture 30 may be provided with the light source comprised by red LED, green LED, and blue LED, for example, and the ratio of the light output of red LED, green LED, and blue LED is adjusted to the illumination controller 20. Then, the color temperature of the light output from the luminaire 30 may be changed to adjust the color. Moreover, the lighting fixture 30 may include a plurality of light sources composed of, for example, near-ultraviolet LEDs and RGB phosphors, and the lighting fixture 30 is adjusted by adjusting the light output ratio of each light source to the lighting controller 20. Toning may be performed by changing the color temperature of the output light. That is, the lighting fixture 30 should just be a lighting fixture which can change color temperature.

[Lighting control method]
Next, the lighting control method will be described.

  FIG. 2 is a diagram illustrating an example of a lighting control method according to the embodiment.

  As shown in FIG. 2, the lighting control method includes, for example, a dimming control method, a human feeling control method, a brightness control method, and a human feeling / brightness control method. The sensor 21 performs detection according to the lighting control method as described above, and detects, for example, the presence or absence of a person or the brightness according to the lighting control method. In the dimming control method, the sensor 21 does not have to detect the presence of a person or the brightness. In addition, FIG. 2 shows parameters of light characteristics of the lighting fixture 30 controlled in each control method.

  The dimming control method is a method in which the lighting controller 20 controls the dimming rate of the lighting fixture 30. Specifically, in the dimming control method, the schedule controller 10 instructs the lighting controller 20 to control the dimming rate of each lighting fixture 30 to a constant dimming rate. The lighting controller 20 keeps the dimming rate of each lighting fixture 30 constant according to an instruction from the schedule controller 10 regardless of the surrounding environment of the lighting fixture 30 (that is, regardless of the presence or absence of a person or brightness). Control the dimming rate. For example, the schedule controller 10 instructs the lighting controller 20 to control the dimming rate of each lighting fixture 30 to 100%, and the lighting controller 20 sets the dimming rate of each lighting fixture 30 to 100% according to the instruction. To control.

  The human sense control method is a method in which the sensor 21 detects the presence or absence of a person, and the lighting controller 20 controls the dimming rate of the lighting fixture 30 according to the detected presence or absence of the person. The sensor 21 detects whether a person is staying, a person is absent, or a person is moving by detecting the presence or absence of a person. Here, the dimming rate of the lighting fixture 30 illuminating the area where the person is staying is the dimming rate, and the dimming rate of the lighting fixture 30 illuminating the area where the person is moving is dimming. The dimming rate of the luminaire 30 that illuminates the area where no person is present is called the absent dimming rate. Specifically, in the human presence control method, the following operations are performed.

  The schedule controller 10 instructs the lighting controller 20 to control the dimming rate of the lighting fixture 30 to the stay dimming rate, the moving dimming rate, or the absent dimming rate. Next, the sensor 21 detects the presence or absence of a person. Thereby, the lighting controller 20 can recognize that the area illuminated by each of the lighting fixtures 30 is an area where a person is staying, an area where a person is moving, or an area where no person is present. . Then, the lighting controller 20 controls the dimming rate of the lighting fixture 30 that illuminates the area detected when the person is staying to the stay dimming rate, and illuminates the area detected when the person is moving. The dimming rate of the lighting fixture 30 to be controlled is controlled to the moving dimming rate, and the dimming rate of the lighting fixture 30 that illuminates the area detected as being absent is controlled to the absent dimming rate.

  For example, the schedule controller 10 instructs the lighting controller 20 to control the stay dimming rate to 100%, the moving dimming rate to 60%, and the absent dimming rate to 5%. The lighting controller 20 has an area in which the dimming rate of the lighting fixture 30 that illuminates the area where it is detected that the person is staying is 100% and the person is detected as moving according to the detection result of the sensor 21 The dimming rate of the lighting fixture 30 that illuminates the lighting fixture 30 is controlled to 60%, and the dimming rate of the lighting fixture 30 that illuminates the area detected as being absent is controlled to 5%.

  In the brightness control method, the sensor 21 detects the brightness (illuminance), and the illumination controller 20 controls the dimming rate of the lighting fixture 30 to the dimming rate corresponding to the target illuminance according to the detected brightness. It is. Specifically, in the brightness control method, the schedule controller 10 controls the dimming rate of the lighting fixture 30 to a dimming rate at which the brightness of the area illuminated by each of the lighting fixtures 30 becomes the target illuminance. To the lighting controller 20. Next, the sensor 21 detects brightness. Thereby, the illumination controller 20 can recognize the brightness of the area | region where the brightness differs according to how each of the lighting fixtures 30 is illuminating, for example, how external light enters. Then, the lighting controller 20 controls the dimming rate of each of the lighting fixtures 30 according to the brightness detected by the sensor 21, thereby setting the brightness of the area illuminated by each of the lighting fixtures 30 to the target illuminance. .

  For example, the schedule controller 10 instructs the lighting controller 20 to control the dimming rate of the lighting fixture 30 by setting the target illuminance to 700 lx. The lighting controller 20 controls the dimming rate of each of the lighting fixtures 30 according to the detection result of the sensor 21 so that the brightness of the area illuminated by each of the lighting fixtures 30 becomes 700 lx.

  The human feeling / brightness control method is a method combining the human feeling control method and the brightness control method. Specifically, in the human feeling / brightness control method, the sensor 21 detects the presence and brightness of a person, and the lighting controller 20 controls the dimming rate of the lighting fixture 30 according to the detected presence and brightness of the person. This is a method for controlling. In the human feeling / brightness control method, more specifically, the following operations are performed.

  For example, the schedule controller 10 controls the dimming rate of the lighting fixture 30 to a dimming rate, a moving dimming rate, or an absent dimming rate at which the brightness of the area illuminated by the lighting fixture 30 becomes the stay target illuminance. To the lighting controller 20. Next, the sensor 21 detects the presence and brightness of a person. Thereby, the lighting controller 20 can recognize that the area illuminated by each of the lighting fixtures 30 is an area where a person is staying, an area where a person is moving, or an area where no person is present. Moreover, the lighting controller 20 can recognize the brightness of the area illuminated by each of the lighting fixtures 30. Then, the lighting controller 20 controls the dimming rate of the luminaire 30 that illuminates the area detected that the person is staying according to the brightness detected by the sensor 21, so that the person stays. The brightness of the area is set as the target illuminance. Moreover, the illumination controller 20 controls the dimming rate of the lighting fixture 30 that illuminates an area where it is detected that a person is moving to the moving dimming rate, and illuminates the area where it is detected that a person is absent. The dimming rate of the luminaire 30 is controlled to the absent dimming rate. In other words, the dimming rate of the lighting fixture 30 that illuminates the area where the person is staying is controlled according to the brightness.

  For example, the schedule controller 10 instructs the lighting controller 20 to control the dimming rate by setting the stay target illuminance to 700 lx. For example, the schedule controller 10 instructs the illumination controller 20 to control the moving dimming rate to 60% and the absent dimming rate to 5%. The illumination controller 20 controls the dimming rate of the luminaire 30 that illuminates the area so that the brightness of the area detected when a person is staying is 700 lx, according to the detection result of the sensor 21. To do. Moreover, the lighting controller 20 detects 60% of the dimming rate of the lighting fixture 30 that is illuminating the area where it is detected that the person is moving, and that the person is absent, according to the detection result of the sensor 21. The dimming rate of the luminaire 30 that illuminates the area is controlled to 5%. Note that the dimming rate of the lighting fixture 30 that is illuminating a region where a person is moving or is absent may be controlled according to the brightness.

  Further, the schedule controller 10 instructs the lighting controller 20 to control the color temperature of the lighting fixture 30 regardless of the lighting control method. And the lighting controller 20 controls the color temperature of the lighting fixture 30 according to the instruction | indication from the schedule controller 10 irrespective of a lighting control system (that is, irrespective of the detection result of the sensor 21). For example, the schedule controller 10 instructs the lighting controller 20 to control the color temperature to 6000K, and the lighting controller 20 controls the color temperature of the lighting fixture 30 to 6000K according to the instruction.

  Thus, the object which the sensor 21 detects differs according to the lighting control method. Further, the target dimming rates of the lighting fixtures 30 controlled by the lighting controller 20 are different depending on the detection result of the sensor 21. In the dimming control method, the dimming rate of each lighting fixture 30 is controlled to a constant dimming rate regardless of the detection result of the sensor 21.

[Predetermined schedule]
FIG. 3 is a diagram illustrating an example of a predetermined schedule according to the embodiment.

  The schedule controller 10 instructs the lighting controller 20 to change the lighting control method of the lighting fixture 30 and the target values of the parameters of the light characteristics according to a predetermined schedule, for example, in a schedule as shown in FIG. Do. As shown in FIG. 3, the change of time zone (when the lighting control method or the target value changes) is set to 0:00 (24:00), 6:00, 12:00, and 18:00. For example, according to a predetermined schedule, the lighting control method is a dimming control method in the time zone from 0 o'clock to 6 o'clock, and the human feeling / brightness in the time zone from 6 o'clock to 12 o'clock and from 12 o'clock to 18 o'clock In the control system, the time control period changes from 18:00 to 24:00. The target value of the optical characteristic parameter is the first target value in the time zone from 0 o'clock to 6 o'clock, the second target value in the time zone from 6 o'clock to 12 o'clock, and the time zone from 12 o'clock to 18 o'clock. The third target value changes to the fourth target value in the time zone from 18:00 to 24:00. Thus, the target value of the lighting control method and the parameter of the light characteristic can be changed according to a predetermined schedule.

  For example, on a floor of a general company or the like, in the midnight time zone (for example, from 0:00 to 6:00), since there are few people, the sensor 21 does not detect the presence or absence of people, and it is bright because there is little outside light. It is preferable not to detect the thickness. Therefore, the schedule controller 10 instructs the illumination controller 20 to change to the dimming control method in the midnight time zone, and instructs the first target value as the parameter of the light characteristics.

  In the early morning to noon time period (for example, from 6:00 to 12:00), there are many places where people are staying on the floor, places where people are moving, and places where people are absent. It is preferable to detect the presence or absence of a person and to detect the brightness because the brightness of external light changes over time. Therefore, the schedule controller 10 instructs the lighting controller 20 to change to the human feeling / brightness control method from the early morning to the evening, and instructs the second target value as the parameter of the light characteristics.

  The schedule controller 10 also instructs the lighting controller 20 to change to the human feeling / brightness control method in the time zone from noon to evening (for example, from 12:00 to 18:00), and sets the parameters of the light characteristics. The target value of 3 is indicated.

  In the night time zone (for example, from 18:00 to 24:00), there are many places where people are staying on the floor, places where people are moving, and places where people are absent. It is preferable not to detect the brightness because the presence or absence is detected and there is little external light. Therefore, the schedule controller 10 instructs the lighting controller 20 to change to the human body control method in the night time zone, and instructs the fourth target value for the parameter of the light characteristics. Note that the predetermined schedule is not limited to that shown in FIG. 3, but may be set according to the environment or the like in which the lighting system 1 is installed. In addition, the lighting control method or the target value does not necessarily change at the change of the time zone (when the lighting control method or the target value changes). Hereinafter, before and after the change of the time zone, it is called before the time zone changes and after the time zone changes.

[Operation of lighting system when lighting control method after change is the same as lighting control method before change]
Next, the lighting system 1 when the lighting control method after the change of the time zone is the same as the lighting control method before the change of the time zone (when the lighting control method after the change is the same as the lighting control method before the change) Will be described with reference to FIGS. When the lighting control method after the time zone changes is the same as the lighting control method before the time zone changes, the time zone from 6 o'clock to 12 o'clock and the time zone from 12 o'clock to 18 o'clock shown in FIG. In this way, the lighting control method is the same before and after the change of the time zone (here, when the target value changes).

  FIG. 4 is a flowchart showing an example of the operation of the illumination system 1 according to the embodiment. In FIG. 4, before step S <b> 11, the schedule controller 10 instructs the lighting controller 20 to change the lighting control method of the lighting fixture 30 according to a predetermined schedule. That is, the schedule controller 10 and the lighting controller 20 (sensor 21) recognize the current lighting control method.

  First, the schedule controller 10 gives a predetermined fade instruction to the lighting controller 20 for changing the dimming rate and the color temperature of the lighting fixture 30 toward the target dimming rate and the target color temperature in a stepwise manner. This is performed for each divided time during the time (S11). Here, during the predetermined time, the schedule controller 10 causes the lighting controller 20 to change the dimming rate and the color temperature of the lighting fixture 30 to the target dimming rate and the target color temperature. It is the time you spend. In other words, the schedule controller 10 causes the lighting controller 20 to change the dimming rate and the color temperature of the lighting fixture 30 over a predetermined time instead of immediately changing to the target dimming rate and the target color temperature. Give instructions. At this time, the schedule controller 10 gives the lighting controller 20 a fade instruction for changing the dimming rate and the color temperature of the lighting fixture 30 step by step (the fade instruction will be described later with reference to FIG. 5). To explain).

  Next, the sensor 21 performs detection according to the lighting control method (S12). When the lighting control method is the humanity control method, the sensor 21 detects the presence or absence of a person in the area illuminated by each of the lighting fixtures 30. When the lighting control method is the brightness control method, the sensor 21 detects the brightness in the area illuminated by each of the lighting fixtures 30. When the lighting control method is the human feeling / brightness control method, the sensor 21 detects the presence and brightness of a person in the area illuminated by each of the lighting fixtures 30. As described above, when the lighting control method is the dimming control method, the sensor 21 does not have to detect the presence or absence of a person or the brightness.

  Next, the lighting controller 20 selectively changes the parameter of the light characteristic of the lighting fixture 30 in accordance with the fade instruction and the detection result of the sensor 21. Specifically, the lighting controller 20 directs the dimming rate of the luminaire 30 to the target dimming rate step by step for each predetermined period of time according to the fade instruction and the detection result of the sensor 21. In response to the fade instruction, the color temperature of the luminaire 30 is changed stepwise toward the target color temperature for each division time for a predetermined time (S13). The operation in step S13 will be described in detail with reference to FIGS.

  Then, the lighting system 1 determines whether or not the dimming rate and the color temperature of the lighting fixture 30 have reached the target dimming rate and the target color temperature (S14). For example, the lighting system 1 determines whether or not the schedule controller 10 has performed a fade instruction to change the dimming rate and the color temperature of the lighting fixture 30 to the target dimming rate and the target color temperature. It is determined whether or not the dimming rate and the color temperature of the appliance 30 have reached the target dimming rate and the target color temperature. When the lighting system 1 determines that the dimming rate and the color temperature of the lighting fixture 30 are not the target dimming rate and the target color temperature (No in S14), the dimming rate and the color temperature of the lighting fixture 30 Until the target dimming rate and target color temperature are reached, the operations in steps S11 to S13 are repeated.

  Here, the fade instruction that the schedule controller 10 gives to the illumination controller 20 in step S11 will be described.

  FIG. 5 is a diagram illustrating an example of a fade instruction according to the embodiment.

  FIG. 5 shows a fade instruction when the lighting control method before the time zone is changed is the same human body control method as the lighting control method after the time zone is changed. The fade instruction is an instruction given for each divided time in order to change the dimming rate and the color temperature of the lighting fixture 30 step by step, and is information indicating the dimming rate and the color temperature, for example. The fade instruction in the motion control method shown in FIG. 5 is information indicating, for example, the stay dimming rate, the moving dimming rate, the absent dimming rate, and the color temperature. Specifically, the fade instructions given for each divided time in the motion control method are the stay dimming rate, the moving dimming rate, the absent dimming rate, and the color shown for each row (division time) in FIG. It is information indicating temperature.

  In FIG. 5, the dimming rate before the time zone changes is, for example, 100% as the stay dimming rate for the lighting fixture 30 that illuminates the area where the person is staying, and the area where the person is moving is illuminated. For the lighting fixture 30 that is being operated, the moving dimming rate is 60%, and for the lighting fixture 30 that is illuminating the area where no one is present, the absence dimming rate is 5%. The color temperature before the time zone changes is, for example, 6000 K for any lighting fixture 30. The target dimming rate is, for example, 70% as the target stay dimming rate for the lighting fixture 30 that illuminates the area where the person is staying, and the illumination that is illuminating the area where the person is moving The target moving dimming rate is set to 30% for the fixture 30, and the target absent dimming rate is set to 5% for the lighting fixture 30 that illuminates an area where no person is present. The target color temperature is, for example, 3000K for any lighting fixture 30. Further, the predetermined time is, for example, 60 minutes, and the division time is, for example, 1 minute.

  Here, the fade instruction will be described by taking the stay dimming rate in the information included in the fade instruction as an example.

  The schedule controller 10 changes the stay dimming rate for the lighting controller 20 from the stay dimming rate before the time zone changes to the target stay dimming rate after the time zone changes for each divided time. Then, an instruction is given so that the value obtained by subtracting the target dimming rate after the change of the time zone from the stay dimming rate before the time zone changes is approximated by a value divided by a predetermined time. When the target value after the time zone changes is larger than the value before the time zone changes, the value before the time zone changes is subtracted from the target value after the time zone changes. For example, with respect to the lighting controller 20, the schedule controller 10 changes the stay dimming rate from 100% that is the stay dimming rate before the time zone is changed to 70% that is the target stay dimming rate. Each minute is instructed to approach 0.5%, which is 100% minus 30% divided by 60 minutes. As shown in FIG. 5, for example, a fade instruction given at the time zone change (0 minutes shown in FIG. 5) is subtracted 0.5% from 100% which is the stay dimming rate before the time zone changes. The information indicating the stay dimming rate of 99.5% is included. Then, the fade instruction given after 1 minute includes information indicating the stay dimming rate 99% obtained by subtracting 0.5% from 99.5%. As described above, the schedule controller 10 gives the lighting controller 20 a fade instruction including information indicating the stay dimming rate approaching the target stay dimming rate for each divided time (1 minute). The fade instruction given at 59 minutes shown in FIG. 5 includes information indicating the target stay dimming rate (70%), and the schedule controller 10 sets the stay dimming rate to the lighting controller 20 as a target. Change to stay dimming rate.

  In addition, the schedule controller 10 instructs the illumination controller 20 to fade every minute so that the movement dimming rate is changed from 60% to 30% over 60 minutes. The explanation about the moving dimming rate is the same as the explanation about the stay dimming rate except that the moving dimming rate before the time zone changes is 60% and the target dimming rate is 30%. The description is omitted.

  In addition, the schedule controller 10 has the absence dimming rate before the time zone is changed to 5% and the target absent dimming rate is 5% with respect to the lighting controller 20, A fade instruction not to change the absent light control rate at 5% is given every minute.

  In addition, the schedule controller 10 instructs the lighting controller 20 to fade every minute so as to change the color temperature from 6000K to 3000K over 60 minutes. The explanation about the color temperature is the same as the explanation about the stay dimming rate except that the color temperature before the time zone is changed is 6000 K and the target color temperature is 3000 K, and thus the explanation is omitted.

  As described above, when the lighting control method before the time zone is changed is the same human body control method as the lighting control method after the time zone is changed, the fade instruction includes the stay dimming rate, the moving dimming rate, and the absence dimming rate. Information indicating the light rate and information indicating the color temperature are included. The fade instruction changes the dimming rate and the color temperature of the lighting fixture 30 step by step toward the target stay dimming rate, the moving dimming rate and the absent dimming rate, and the target color temperature. It is performed every divided time.

  Similarly, when the lighting control method before the change of the time zone is the same brightness control method as the lighting control method after the change of the time zone, the fade instruction indicates the target for the area illuminated by each of the lighting fixtures 30. It includes information indicating illuminance and information indicating color temperature. The fade instruction is a stepwise adjustment of the dimming rate and the color temperature of the lighting fixture 30 toward the dimming rate and the target color temperature at which the area illuminated by each of the lighting fixtures 30 becomes the target illuminance. In order to change, it is performed at every divided time.

  Similarly, when the lighting control method before the change of the time zone is the same feeling / brightness control method as the lighting control method after the change of the time zone, the fade instruction is the stay target for the area where the person is staying It includes information indicating illuminance, information indicating the moving dimming rate and absent dimming rate, and information indicating the color temperature. Then, the fade instruction indicates the dimming rate and the color temperature of the luminaire 30, the dimming rate at which the area where the person is staying becomes the stay target illuminance, the target moving dimming rate and the absent dimming rate, and the target This is performed at every divided time in order to change the color temperature stepwise.

  Similarly, when the lighting control method before the time zone changes is the same dimming control method as the lighting control method after the time zone changes, the fade instruction includes information indicating the dimming rate and information indicating the color temperature. Including. And a fade instruction | indication is performed for every division | segmentation time in order to change the light control rate and color temperature of the lighting fixture 30 in steps toward a target light control rate and a target color temperature.

  Next, operation | movement of the illumination controller 20 in step S13 is demonstrated using FIGS.

  FIG. 6 is a diagram illustrating an example of the operation of the lighting controller 20 according to the embodiment when the lighting control method is the motion control method before and after the time zone changes.

  For example, as the target values of the light characteristic parameters before the time zone changes, the stay dimming rate is 100%, the moving dimming rate is 60%, the absent dimming rate is 5%, and the color temperature is 6000K. It is assumed that the dimming rate and the color temperature of the lighting fixture 30 before the time zone is changed have been changed to the target values. Further, for example, as the target values after the time zone has changed, the stay dimming rate is 70%, the moving dimming rate is 30%, the absent dimming rate is 5%, and the color temperature is 3000K. FIG. 6 shows an example of the operation of the illumination controller 20 when changing the dimming rate of the luminaire 30 that illuminates a region where it is detected that a person is staying.

  The schedule controller 10 gives a fade instruction to the lighting controller 20 for each predetermined time during a predetermined time. Therefore, the lighting controller 20 receives a fade instruction for each divided time from the change of the time zone. Here, the fade instruction is, for example, the fade instruction shown in FIG. Further, the sensor 21 detects the presence or absence of a person in the area illuminated by each of the lighting fixtures 30 according to the human feeling control method. At this time, the fade instruction includes information indicating the stay dimming rate, the moving dimming rate, and the absent dimming rate, and information indicating the color temperature. The lighting controller 20 can recognize the lighting fixture 30 that is illuminating the area where the person is staying, the area where the person is moving, and the area where the person is absent, according to the detection result of the sensor 21. Therefore, the lighting controller 20 adjusts the lighting fixture 30 that illuminates the area detected when a person is staying, for example, as shown in FIG. 6, according to the fade instruction and the detection result of the sensor 21. The rate is changed in steps toward the target stay dimming rate step by step for each predetermined period of time.

  Specifically, for example, the lighting controller 20 steps the dimming rate of the luminaire 30 that illuminates an area detected as a person staying, every minute for 60 minutes from the turn of the time zone. Therefore, the target dimming rate is changed from 100% to a target stay dimming rate of 70%. Similarly, the lighting controller 20 adjusts the dimming rate of the lighting fixture 30 that illuminates the area where the person is detected to move for a predetermined time according to the fade instruction and the detection result of the sensor 21. Then, it is changed stepwise toward the target moving light control rate for each divided time. Similarly, according to the fade instruction and the detection result of the sensor 21, the lighting controller 20 adjusts the dimming rate of the lighting fixture 30 that is illuminating the area where the person is absent for a predetermined time. It is changed toward the target absent dimming rate step by step for each division time. Moreover, the lighting controller 20 changes the color temperature of the lighting fixture 30 stepwise toward the target color temperature for each division time during a predetermined time in accordance with the fade instruction. Specifically, for example, the lighting controller 20 changes the color temperature of the lighting fixture 30 stepwise from 6000K to the target color temperature of 3000K every minute for 60 minutes from the time zone change.

  FIG. 7 is a diagram illustrating an example of the operation of the lighting controller 20 according to the embodiment when the lighting control method is the dimming control method before and after the time zone changes.

  For example, as a target value of the light characteristic parameter before the time zone changes, the dimming rate is set to 100% and the color temperature is set to 6000K. It is assumed that the dimming rate and the color temperature of the lighting fixture 30 before the time zone is changed have been changed to the target values. Further, for example, the target dimming rate is 5% and the target color temperature is 3000K as the target values after the time zone has changed.

  The schedule controller 10 gives a fade instruction to the lighting controller 20 for each predetermined time during a predetermined time. Therefore, the lighting controller 20 receives a fade instruction for each divided time from the change of the time zone. At this time, the fade instruction includes information indicating the dimming rate and information indicating the color temperature. In response to the fade instruction, the lighting controller 20 changes the dimming rate of the lighting fixture 30 stepwise toward the target dimming rate for each division time for a predetermined time.

  Specifically, the lighting controller 20 changes the dimming rate of the luminaire 30 from 100% step by step to 1% of the target dimming rate for 60 minutes from the turn of the time zone. Moreover, the lighting controller 20 changes the color temperature of the lighting fixture 30 stepwise toward the target color temperature for each division time during a predetermined time in accordance with the fade instruction. Specifically, for example, the lighting controller 20 changes the color temperature of the lighting fixture 30 stepwise from 6000K to the target color temperature of 3000K every minute for 60 minutes from the time zone change.

  FIG. 8 is a diagram illustrating an example of the operation of the lighting controller 20 according to the embodiment when the lighting control method is the brightness control method before and after the time zone changes.

  For example, the target illuminance is set to 700 lx and the color temperature is set to 6000 K as the target values of the light characteristic parameters before the time zone is changed. It is assumed that the dimming rate and color temperature of the lighting fixture 30 before the time zone changes have already changed to the dimming rate and color temperature at which the illuminance of the area illuminated by the lighting fixture 30 becomes the target illuminance. . Further, for example, the target illuminance is 500 lx and the target color temperature is 3000 K as the target values after the time zone has changed.

  The schedule controller 10 gives a fade instruction to the lighting controller 20 for each predetermined time during a predetermined time. Therefore, the lighting controller 20 receives a fade instruction for each divided time from the change of the time zone. Moreover, the sensor 21 detects the brightness in the area | region which each of the lighting fixture 30 is illuminating according to a brightness control system. At this time, the fade instruction includes information indicating the target illuminance and information indicating the color temperature. The illumination controller 20 changes the illuminance of the area illuminated by the luminaire 30 in a stepwise manner toward the target illuminance for each division time according to the fade instruction and the detection result of the sensor 21. Thus, the light control rate of the lighting fixture 30 is changed.

  Specifically, for example, the illumination controller 20 changes the illuminance of the area illuminated by the luminaire 30 from 700 lx to the target illuminance 500 lx step by step every minute for 60 minutes from the time zone change. Thus, the light control rate of the lighting fixture 30 is changed. Moreover, the lighting controller 20 changes the color temperature of the lighting fixture 30 stepwise toward the target color temperature for each division time during a predetermined time in accordance with the fade instruction. Specifically, for example, the lighting controller 20 changes the color temperature of the lighting fixture 30 stepwise from 6000K to the target color temperature of 3000K every minute for 60 minutes from the time zone change.

  FIG. 9 is a diagram illustrating an example of the operation of the lighting controller 20 according to the embodiment when the lighting control method is the human feeling / brightness control method before and after the time zone changes.

  For example, as target values for the parameters of the light characteristics before the time zone changes, the stay target illuminance is 700 lx, the moving dimming rate is 60%, the absent dimming rate is 5%, and the color temperature is 6000K. It is assumed that the illuminance of the area detected as a person staying before the time zone changes, the dimming rate of the lighting fixture 30, and the color temperature have already changed to the target values. Also, for example, the target target illuminance is 500 lx, the target moving dimming rate is 30%, the target absent dimming rate is 5%, and the target color temperature is 3000K as target values after the time zone has changed. FIG. 9 shows an example of the operation of the lighting controller 20 when the stay target illuminance is changed.

  The schedule controller 10 gives a fade instruction to the lighting controller 20 for each predetermined time during a predetermined time. Therefore, the lighting controller 20 receives a fade instruction for each divided time from the change of the time zone. Further, the sensor 21 detects the presence and brightness of a person in the area illuminated by each of the lighting fixtures 30 in accordance with the human feeling / brightness control method. At this time, the fade instruction includes information indicating the stay target illuminance, the moving dimming rate, and the absent dimming rate, and information indicating the color temperature. The lighting controller 20 can recognize the lighting fixture 30 that is illuminating the area where the person is staying, the area where the person is moving, and the area where the person is absent, according to the detection result of the sensor 21. Accordingly, the illumination controller 20 stays in steps for each predetermined time for the illuminance of the area where it is detected that a person is staying, for example, according to the fade instruction and the detection result of the sensor 21. The dimming rate of the luminaire 30 that illuminates the area detected when a person is staying is changed so as to change toward the target illuminance.

  Specifically, for example, the illumination controller 20 changes the illuminance of an area detected as a person staying from 700 lx stepwise to the target stay illuminance 500 lx every minute for 60 minutes from the time zone change. The dimming rate of the luminaire 30 that illuminates the area detected when a person is staying is changed. Similarly, the lighting controller 20 adjusts the dimming rate of the lighting fixture 30 that illuminates the area where the person is detected to move for a predetermined time according to the fade instruction and the detection result of the sensor 21. Then, it is changed stepwise toward the target moving light control rate for each divided time. Similarly, according to the fade instruction and the detection result of the sensor 21, the lighting controller 20 adjusts the dimming rate of the lighting fixture 30 that is illuminating the area where the person is absent for a predetermined time. It is changed toward the target absent dimming rate step by step for each division time. Moreover, the lighting controller 20 changes the color temperature of the lighting fixture 30 stepwise toward the target color temperature for each division time during a predetermined time in accordance with the fade instruction. Specifically, for example, the lighting controller 20 changes the color temperature of the lighting fixture 30 stepwise from 6000K to the target color temperature of 3000K every minute for 60 minutes from the time zone change.

  In this way, the lighting controller 20 changes the dimming rate of the lighting fixture 30 in accordance with the fade instruction and the detection result of the sensor 21 in a stepwise manner for the predetermined dimming rate or target illuminance for each predetermined time. It is changed toward the dimming rate corresponding to. Moreover, the lighting controller 20 changes the color temperature of the lighting fixture 30 stepwise toward the target color temperature for each division time for a predetermined time in accordance with the fade instruction.

  The lighting controller 20 may have a function of gradually changing, for example, the light characteristic parameter of the lighting fixture 30 to the value of the light characteristic parameter indicated by the fade instruction received from the schedule controller 10 every divided time. . That is, each time the lighting controller 20 receives a fade instruction, the lighting controller 20 may not immediately change the light characteristic parameter of the lighting fixture 30 to the value of the light characteristic parameter indicated in the fade instruction. For example, when the predetermined time is 60 minutes and the division time is 1 minute, the lighting controller 20 has a function of gradually changing the parameters of the light characteristics of the lighting fixture 30 over 1 minute after receiving the fade instruction. May be. Thereby, the parameter of the light characteristic of the lighting fixture 30 does not change immediately every minute, but changes continuously as shown in FIGS. Further, the lighting controller 20 receives a fade instruction in which the light characteristic parameter of the lighting fixture 30 becomes the target value at 59 minutes shown in FIG. 5, and the light characteristic parameter of the lighting fixture 30 is set to the target value from 59 minutes to 1 minute. To change. Thereby, the lighting controller 20 can change the parameter of the optical characteristic of the lighting fixture 30 to the target value after a predetermined time (60 minutes) from the turn of the time zone.

[Operation of lighting system when lighting control method after change is different from lighting control method before change]
By the way, when the lighting control method is different before and after the time zone changes, for example, the lighting control method before the change is the humanity control method or the human feeling / brightness control method, and the lighting control method after the change is the dimming control method or the brightness. In the case of the control method, the user may feel uncomfortable as follows. As an example, a case will be described in which the lighting control method before the change is a human presence control method, and the lighting control method after the change is a dimming control method.

  For example, before the time zone changes, the lighting fixture 30 that illuminates the area where the person is staying is controlled to a dimming rate of 100%, and the lighting fixture 30 that is illuminating the area where the person is absent exists. When the dimming rate is controlled to 5% and the dimming rate is set to 50% step by step after the time zone is changed, the dimming of the luminaire 30 that illuminates the area where the person is staying is controlled. The rate gradually approaches 50% from 100%, and the dimming rate of the luminaire 30 that illuminates an area where no person is present gradually approaches 50% from 5%. Therefore, for example, in one floor, a region that becomes darker from a bright state, a region that becomes brighter from a dark state, or the like may be mixed, giving the user a sense of discomfort.

  Also, if the lighting control method is different before and after the time zone changes, for example, one of the lighting control methods before and after the change is the brightness control method or the human / brightness control method, and the other is the dimming control method, In the case of the control method or the human feeling / brightness control method, it becomes difficult to change the dimming rate step by step as follows. However, when the lighting control method is the human feeling / brightness control method before and after the change, the dimming rate can be changed step by step. As an example, a case where the lighting control method before the change is the brightness control method and the lighting control method after the change is the dimming control method will be described.

  In the case of the brightness control method, the schedule controller 10 instructs the illumination controller 20 of the target illuminance. The illumination controller 20 controls the dimming rate of the lighting fixture 30 from the detection result of the sensor 21 to a dimming rate equivalent to the target illuminance. For example, when the schedule controller 10 communicates unidirectionally with the lighting controller 20, the schedule controller 10 does not recognize the dimming rate corresponding to the target illuminance of the lighting fixture 30 controlled by the lighting controller 20. Therefore, since the schedule controller 10 cannot recognize the dimming rate of the lighting fixture 30 when the lighting control method is changed, the schedule controller 10 is calculated for each divided time calculated from the target dimming rate and the dimming rate when the lighting control method is changed. The instructed dimming rate cannot be calculated. That is, since the schedule controller 10 cannot give a fade instruction, it is difficult to change the dimming rate step by step.

  Thus, when the lighting control method is different before and after the time zone changes, depending on the lighting control method, the user may feel uncomfortable, and it may be difficult to change the dimming rate step by step. .

  Therefore, hereinafter, the operation of the lighting system 1 when the lighting control method after the change is different from the lighting control method before the change will be described with reference to FIGS.

  FIG. 10 is a diagram illustrating an example of a combination of lighting control methods before and after the time zone changes.

  As shown in the hatching column of FIG. 10, the operation of the lighting system 1 when the lighting control method after the change is the same as the lighting control method before the change has been described, but in the following, in the white column of FIG. As shown, the operation of the lighting system 1 when the lighting control method after the change is different from the lighting control method before the change will be described. When the lighting control method after the change is different from the lighting control method before the change, the time zone changes such as the time zone from 0 o'clock to 6 o'clock and the time zone from 6 o'clock to 12 o'clock shown in FIG. This is the case where the lighting control method differs before and after.

  FIG. 11 is a flowchart illustrating another example of the operation of the illumination system 1 according to the embodiment. In FIG. 11, before step S21, the schedule controller 10 instructs the lighting controller 20 to change the lighting control method of the lighting fixture 30 according to a predetermined schedule. That is, the schedule controller 10 and the lighting controller 20 (sensor 21) recognize the current lighting control method.

  First, the schedule controller 10 instructs the lighting controller 20 to change the dimming rate of the lighting fixture 30 to the target dimming rate at the change of the time zone (when the lighting control method is changed) (S21).

  Next, the schedule controller 10 gives the lighting controller 20 a fade instruction for changing the color temperature of the lighting fixture 30 in steps toward the target color temperature for each predetermined period of time. (S22). That is, the schedule controller 10 does not immediately change the color temperature of the lighting fixture 30 to the target color temperature with respect to the lighting controller 20, but changes it over a predetermined time from the change of the lighting control method. Give instructions. At this time, the schedule controller 10 gives the lighting controller 20 a fade instruction for changing the color temperature of the luminaire 30 step by step (the fade instruction will be described later with reference to FIG. 12). .

  Next, the sensor 21 performs detection according to the lighting control method (S23). The operation in step S23 is the same as that in step S12 shown in FIG.

  Next, the lighting controller 20 selectively changes the parameter of the light characteristic of the lighting fixture 30 in accordance with the fade instruction and the detection result of the sensor 21. Specifically, the lighting controller 20 changes the dimming rate of the lighting fixture 30 according to the instruction to change the dimming rate of the lighting fixture 30 to the target dimming rate and the detection result of the sensor 21, and the change of the lighting control method. Sometimes the target dimming rate is changed, and the color temperature of the luminaire 30 is changed stepwise toward the target color temperature for each division time for a predetermined time in accordance with the fade instruction (S24). The operation in step S24 will be described in detail with reference to FIGS. 13 and 14 described later.

  Then, the lighting system 1 determines whether or not the color temperature of the lighting fixture 30 has reached the target color temperature (S25). For example, when the schedule controller 10 determines whether or not a fade instruction for changing the color temperature of the lighting fixture 30 to the target color temperature has been issued, the lighting system 1 determines that the color temperature of the lighting fixture 30 is the target color temperature. It is determined whether or not. When the lighting system 1 determines that the color temperature of the lighting fixture 30 has not reached the target color temperature (No in S25), the lighting system 1 in steps S22 to S24 until the color temperature of the lighting fixture 30 reaches the target color temperature. The operation is repeated.

  Here, the fade instruction that the schedule controller 10 gives to the illumination controller 20 in step S22 will be described.

  FIG. 12 is a diagram illustrating another example of the fade instruction according to the embodiment. However, an instruction for changing the dimming rate of the lighting fixture 30 to the target dimming rate and a fade instruction are shown in the row of 0 minutes (when the lighting control method is changed) shown in FIG.

  FIG. 12 shows a fade instruction when the lighting control method after the change is a human feeling control method and is different from the lighting control method before the change. Here, the fade instruction is an instruction given for each divided time in order to change the color temperature of the lighting fixture 30 in a stepwise manner, and includes information indicating the color temperature. Specifically, each of the fade instructions given for each division time includes information indicating the color temperature shown for each row (division time) in FIG. However, as described above, the 0 minute line shown in FIG. 12 also shows an instruction to change the dimming rate of the lighting fixture 30 to the target dimming rate. The instruction to change to the dimming rate includes information indicating the stay dimming rate, the moving dimming rate, and the absent dimming rate.

  In FIG. 12, the dimming rate before the time zone changes is, for example, 100% as the stay dimming rate for the lighting fixture 30 that illuminates the area where the person is staying, and the area where the person is moving is illuminated. For the lighting fixture 30 that is being operated, the moving dimming rate is 60%, and for the lighting fixture 30 that is illuminating the area where no one is present, the absence dimming rate is 5%. The color temperature before the time zone changes is, for example, 6000 K for any lighting fixture 30. The target dimming rate is, for example, 70% as the target stay dimming rate for the lighting fixture 30 that illuminates the area where the person is staying, and the illumination that is illuminating the area where the person is moving The target moving dimming rate is set to 30% for the fixture 30, and the target absent dimming rate is set to 5% for the lighting fixture 30 that illuminates an area where no person is present. The target color temperature is, for example, 3000K for any lighting fixture 30. Further, the predetermined time is, for example, 60 minutes, and the division time is, for example, 1 minute.

  First, the instruction | indication which changes the light control rate of the lighting fixture 30 to a target light control rate is demonstrated.

  The schedule controller 10 sets the dimming rate of the lighting fixture 30 to the lighting controller 20 based on the stay dimming rate, the moving dimming rate, and the absent dimming rate before the time zone is changed when the lighting control method is changed. It is instructed to change to the stay dimming rate, the moving dimming rate, and the absent dimming rate. For example, the schedule controller 10 sets the dimming rate of the lighting fixture 30 to the lighting controller 20 when the lighting control method is changed, the stay dimming rate 100% before the time zone changes, the moving dimming rate 60%, and An instruction is given to change from the absent light control rate of 5% to the target stay light control rate of 70%, the moving light control rate of 30%, and the absent light control rate of 5%. In this way, the instruction to change the dimming rate of the lighting fixture 30 to the target dimming rate is, for example, once when the lighting control method changes (0 minutes shown in FIG. 12), as shown in FIG. Instruction to be performed.

  Next, a fade instruction will be described.

  The schedule controller 10 changes the color temperature from the color temperature before the time zone is changed to the target color temperature after the time zone is changed, before the time zone is changed for each divided time. An instruction is given so that the value obtained by subtracting the target color temperature after the time zone has changed from the color temperature is divided by a predetermined time. Specifically, the schedule controller 10 causes the lighting controller 20 to change the color temperature from 6000 K, which is the color temperature before the time zone is changed, to 3000 K, which is the target color temperature after the time zone is changed. Each minute is instructed to approach 50K, which is 3000K minus 3000K divided by 60 minutes. As shown in FIG. 12, for example, in a fade instruction performed when the lighting control method changes (0 minutes shown in FIG. 12), a color temperature obtained by subtracting 50K from 6000K which is the color temperature before the time zone changes. Information indicating 5950K is included. Then, the fade instruction given after one minute includes information indicating a color temperature of 5900K obtained by subtracting 50K from 5950K. As described above, the schedule controller 10 issues a fade instruction including information indicating the color temperature approaching the target color temperature to the illumination controller 20 every divided time (1 minute). 12 includes information indicating the target color temperature (3000 K), and the schedule controller 10 changes the color temperature to the target color temperature with respect to the lighting controller 20. Let

  Thus, when the lighting control method after the change is different from the lighting control method before the change, the fade instruction includes information indicating the color temperature. And a fade instruction | indication is performed for every division | segmentation time in order to change the color temperature of the lighting fixture 30 in steps toward a target color temperature.

  Moreover, the instruction | indication which changes the light control rate of the lighting fixture 30 to a target light control rate is performed once, for example at the time of a lighting control system change, and contains the information according to the lighting control system after a change. For example, when the lighting control method after the change is the human presence control method, the instruction to change the dimming rate of the lighting fixture 30 to the target dimming rate is the stay dimming rate, the moving dimming rate, and the absent dimming rate. Contains information to indicate. When the lighting control method after the change is the brightness control method, the instruction to change the dimming rate of the lighting fixture 30 to the target dimming rate includes information indicating the target illuminance. When the lighting control method after the change is the human feeling / brightness control method, the instruction to change the dimming rate of the lighting fixture 30 to the target dimming rate is the target illumination intensity, the moving dimming rate, and the absent dimming rate. Contains information to indicate. When the lighting control method after the change is the dimming control method, the instruction to change the dimming rate of the lighting fixture 30 to the target dimming rate includes information indicating the dimming rate.

  Next, operation | movement of the illumination controller 20 in step S24 is demonstrated using FIG.

  FIG. 13 is a diagram illustrating an example of the operation of the lighting controller 20 according to the embodiment when the lighting control method is different before and after the time zone changes. FIG. 13 shows the operation of the illumination controller 20 when the lighting control method before the change is the dimming control method and the lighting control method after the change is the human presence control method among the combinations shown in FIG.

  For example, as a target value before the time zone changes, the dimming rate is set to 100% and the color temperature is set to 6000K. It is assumed that the dimming rate and the color temperature of the lighting fixture 30 before the time zone is changed have been changed to the target values. Further, for example, as the target values after the time zone has changed, the stay dimming rate is 70%, the moving dimming rate is 30%, the absent dimming rate is 5%, and the color temperature is 3000K. FIG. 13 shows an example of the operation of the lighting controller 20 when changing the dimming rate of the luminaire 30 that illuminates an area where it is detected that a person is absent after the time zone has changed. .

  The schedule controller 10 issues a fade instruction to the lighting controller 20 for each predetermined period of time for a predetermined time from when the lighting control method changes (change of time zone). Further, the schedule controller 10 instructs the lighting controller 20 to change the dimming rate of the lighting fixture 30 to the target dimming rate when the lighting control method is changed. Accordingly, the lighting controller 20 receives a fade instruction for each divided time from the time when the lighting control method changes. Moreover, the illumination controller 20 receives the instruction | indication which changes the light control rate of the lighting fixture 30 to a target light control rate at the time of a lighting control system change. Here, the fade instruction and the instruction for changing the dimming rate of the lighting fixture 30 to the target dimming rate are, for example, changing the fade instruction and the dimming rate of the lighting fixture 30 shown in FIG. 12 to the target dimming rate. Instructions. Further, the sensor 21 detects the presence or absence of a person in the area illuminated by each of the lighting fixtures 30 according to the human feeling control method. At this time, the instruction to change the dimming rate of the lighting fixture 30 to the target dimming rate includes information indicating the stay dimming rate, the moving dimming rate, and the absent dimming rate. However, the lighting controller 20 can recognize the lighting fixture 30 that is illuminating the area where the person is staying, the area where the person is moving, and the area where the person is absent, according to the detection result of the sensor 21. Therefore, the lighting controller 20 detects that a person is absent, for example, as shown in FIG. 13, according to the instruction to change the dimming rate of the lighting fixture 30 to the target dimming rate and the detection result of the sensor 21. The dimming rate of the luminaire 30 that illuminates the selected area is changed to the target absent dimming rate when the lighting control method is changed.

  Specifically, for example, the lighting controller 20 changes the dimming rate of the lighting fixture 30 that illuminates an area where it is detected that a person is absent from a target absent dimming rate from 100% when the lighting control method changes. The rate is changed to 5%. Similarly, the lighting controller 20 changes the dimming rate of the lighting fixture 30 that is illuminating the area where it is detected that a person is staying according to the fade instruction and the detection result of the sensor 21, and changes the lighting control method. Sometimes change towards the desired dimming rate. Similarly, the lighting controller 20 changes the dimming rate of the lighting fixture 30 that illuminates an area where a person is detected to be moving according to the fade instruction and the detection result of the sensor 21, and changes the lighting control method. Sometimes change towards the target dimming rate. Moreover, the lighting controller 20 changes the color temperature of the lighting fixture 30 stepwise toward the target color temperature for each division time during a predetermined time in accordance with the fade instruction. Specifically, for example, the lighting controller 20 changes the color temperature of the lighting fixture 30 stepwise from 6000K to the target color temperature of 3000K every minute for 60 minutes from the change of the lighting control method.

  FIG. 14 is a diagram illustrating another example of the operation of the lighting controller 20 according to the embodiment when the lighting control method is different before and after the time zone changes. FIG. 14 shows the operation of the illumination controller 20 when the lighting control method before the change is the dimming control method and the lighting control method after the change is the brightness control method among the combinations shown in FIG.

  For example, as a target value before the time zone changes, the dimming rate is set to 100% and the color temperature is set to 6000K. It is assumed that the dimming rate and the color temperature of the lighting fixture 30 before the time zone is changed have been changed to the target values. Further, for example, the target illuminance is 500 lx and the target color temperature is 3000 K as the target values after the time zone has changed.

  The schedule controller 10 issues a fade instruction to the lighting controller 20 for each predetermined period of time for a predetermined time from when the lighting control method changes (change of time zone). Further, the schedule controller 10 instructs the lighting controller 20 to change the dimming rate of the lighting fixture 30 to the target dimming rate when the lighting control method is changed. Accordingly, the lighting controller 20 receives a fade instruction for each divided time from the time when the lighting control method changes. Moreover, the illumination controller 20 receives the instruction | indication which changes the light control rate of the lighting fixture 30 to a target light control rate at the time of a lighting control system change. Moreover, the sensor 21 detects the brightness in the area | region which each of the lighting fixture 30 is illuminating according to a brightness control system. The lighting controller 20 changes the illuminance of the area illuminated by the lighting fixture 30 according to the instruction to change the dimming rate of the lighting fixture 30 to the target dimming rate and the detection result of the sensor 21 in the lighting control method. The dimming rate of the luminaire 30 is changed so that the target illuminance is sometimes changed.

  Specifically, for example, the lighting controller 20 adjusts the dimming rate of the lighting fixture 30 to 500 lx so that the illuminance of the area illuminated by the lighting fixture 30 is changed to the target illuminance 500 lx when the lighting control method is changed. Change the dimming rate. Moreover, the lighting controller 20 changes the color temperature of the lighting fixture 30 stepwise toward the target color temperature for each division time during a predetermined time in accordance with the fade instruction. Specifically, for example, the lighting controller 20 changes the color temperature of the lighting fixture 30 stepwise from 6000K to the target color temperature of 3000K every minute for 60 minutes from the change of the lighting control method.

  In this way, the lighting controller 20 changes the light control rate of the lighting fixture 30 to the target light control rate when the lighting control method is changed according to the instruction to change the light control rate of the lighting fixture 30 to the target light control rate and the detection result of the sensor 21. . Moreover, the lighting controller 20 changes the color temperature of the lighting fixture 30 stepwise toward the target color temperature for each division time for a predetermined time in accordance with the fade instruction.
