Alternatively, a plurality of sockets to which a plurality of lights 130 having a large luminous flux (lumen (lm)) or a light 130 having a large luminous flux are attached are allocated to the same group. Alternatively, a plurality of sockets to which a plurality of lights 130 having a maximum maximum power consumption or a light 130 having a maximum maximum power consumption should be attached are allocated to the same group.

  The information on the illuminance sensor is for specifying the illuminance sensor 120 corresponding to the light 130. In the present embodiment, one illuminance sensor 120 is associated with each of the plurality of lights 130A to 130F. However, one illuminance sensor 120 may be associated with two or more lights 130. Conversely, two or more illuminance sensors 120 may be associated with one light 130. That is, the home controller 100 may use the average value of the illuminance from the two or more illuminance sensors 120 as the illuminance of the corresponding light 130.

  FIG. 4 is an image diagram showing the daytime table 101B according to the present embodiment. Referring to FIG. 4, daytime table 101B stores a time zone in which sunlight is inserted into a room for each period. That is, the daytime table 101B makes the light intensity (power consumption) of the window-side lights 130A, 130B, and 130E weaker than the light intensity (power consumption) of the indoor lights 130C, 130D, and 130F for each period. Stores the power time zone.

  In the present embodiment, the daytime table 101B stores daytime corresponding to two types of periods, but may store daytime corresponding to three or more types of periods.

  Returning to FIG. 2, the display 102 displays various information under the control of the CPU 110. The tablet 103 detects a touch operation with a user's finger and inputs touch coordinates or the like to the CPU 110. The CPU 110 receives a command from the user via the tablet 103.

  In the present embodiment, a tablet 103 is laid on the surface of the display 102. That is, in the present embodiment, display 102 and tablet 103 constitute touch panel 106. However, the home controller 100 does not have to include the tablet 103.

  The button 104 is disposed on the surface of the home controller 100. A plurality of buttons such as a numeric keypad may be arranged on the home controller 100. The button 104 receives various commands from the user. The button 104 inputs a command from the user to the CPU 110.

  The first communication interface 105 transmits / receives data to / from the plurality of lights 130 </ b> A to 130 </ b> F via the network by being controlled by the CPU 110. As described above, the first communication interface 105 transmits and receives data to and from the plurality of lights 130A to 130F by using a wired LAN, a wireless LAN, a PLC, ZigBee (registered trademark), or Bluetooth (registered trademark). To do.

  The second communication interface 107 transmits / receives data to / from the server 300 via the network by being controlled by the CPU 110. As described above, the second communication interface 107 transmits / receives data to / from the server 300 by using the Internet, carrier network, WAN, LAN, ZigBee (registered trademark), Bluetooth (registered trademark), or the like.

  However, the first communication interface 105 and the second communication interface 107 may be one communication interface (one device).

  The speaker 108 outputs various information (for example, a voice message, a beep sound, etc.) by being controlled by the CPU 110.

  The timer 109 measures time or a period based on a command from the CPU 110. For example, the timer 109 measures a period from when the light 130 is turned on to off, or a period from when the light intensity of the light 130 is changed to when the light intensity is changed next, and passes the measured time to the CPU 110. The CPU 110 updates the accumulated power consumption of the write table 101A based on the period and the power consumption.

  The CPU 110 executes various programs stored in the memory 101. Processing in the home controller 100 (for example, processing shown in FIGS. 5 to 8, 11, and 12) is realized by each hardware and software executed by the CPU 110. Such software may be stored in the memory 101 in advance. The software may be stored in a storage medium and distributed as a program product. Alternatively, the software may be provided as a program product that can be downloaded by an information provider connected to the so-called Internet.

  Such software is read from the storage medium by using a reading device (not shown), or downloaded by using the first communication interface 105 or the second communication interface 107 and stored in the memory 101. Once stored. The CPU 110 stores the software in the form of an executable program in the memory 101 and then executes the program.

  As storage media, CD-ROM (Compact Disc-Read Only Memory), DVD-ROM (Digital Versatile Disk-Read Only Memory), USB (Universal Serial Bus) memory, memory card, FD (Flexible Disk), hard disk , Magnetic tape, cassette tape, MO (Magnetic Optical Disc), MD (Mini Disc), IC (Integrated Circuit) card (excluding memory card), optical card, mask ROM, EPROM, EEPROM (Electronically Erasable Programmable Read-Only Memory) And the like, for example, a medium for storing the program in a nonvolatile manner.

  The program here includes not only a program directly executable by the CPU but also a program in a source program format, a compressed program, an encrypted program, and the like.

  The CPU 110 refers to the daytime table 101B and determines whether it is daytime or nighttime based on the time from the timer 109. Alternatively, the CPU 110 may determine that it is daytime when the illuminance of the window-side illuminance sensors 120A, 120C, and 120E in a state where the plurality of lights 130A to 130F are not lit is equal to or greater than a predetermined value.

  In the daytime, the CPU 110 sets the light intensity (power consumption) of the first light 130A, the second light 130B, and the fifth light 130E arranged on the window side (a relatively bright area in the daytime) to the indoor side (daytime). The light intensity (power consumption) of the third light 130C, the fourth light 130D, and the sixth light 130F arranged in a relatively dark area is set to be smaller.

  As a result, the amount of power consumed by the lights 130A, 130B, and 130E on the window side can be reduced by effectively using sunlight during the daytime. However, during the daytime, the increase in the accumulated power consumption of the lights 130A, 130B, 130E on the window side is smaller than the increase in the accumulated power consumption of the lights 130C, 130D, 130F on the indoor side.

  At night, the CPU 110 determines the light of the first light 130A, the second light 130B, and the fifth light 130E arranged on the window side (a relatively bright area during the day) based on the magnitude of the accumulated power consumption. The first communication interface so that the intensity is higher than the intensity of light of the third light 130C, the fourth light 130D, and the sixth light 130F disposed on the indoor side (a relatively dark area in the daytime). The plurality of lights 130 </ b> A to 130 </ b> F are controlled via 105.

  In the present embodiment, CPU 110 acquires illuminance from the plurality of illuminance sensors 120A to 120F via first communication interface 105 when the plurality of lights 130A to 130F are turned off in the daytime. . The CPU 110 sets the area where the illuminance sensors 120A, 120B, 120E with high illuminance are arranged as the first area (a relatively bright area in the daytime), and arranges the illuminance sensors 120C, 120D, 120F with lower illuminance. The set area is set as a second area (a relatively dark area in the daytime). Alternatively, the CPU 110 sets the lights 130A, 130B, and 130E corresponding to the illuminance sensors 120A, 120B, and 120E having high illuminance to the first light (light that weakens the intensity during the day and increases the intensity at the night), and the illuminance is low. The lights 130C, 130D, and 130F corresponding to the illuminance sensors 120C, 120D, and 120F are set as the second lights (lights that reduce the intensity at night).

  Or CPU110 selects the 1st light (light which weakens an intensity | strength in the daytime and increases the intensity | strength at night) from the light | write | right 130A-130F from a user via the button 104 or the touch panel 106 from the user. And a command for selecting a second light (light that weakens the intensity at night) far from the window from among the plurality of lights 130A to 130F. In other words, the CPU 110 may accept a command for setting whether each of the plurality of lights 130A to 130F is the first light or the second light.

  Thereby, in the network system 1 according to the present embodiment, it is possible to make the integrated power consumption of the plurality of lights more uniform than in the past while considering the light intensity required for each of the plurality of lights.

<Light mounting process in home controller 100>
Next, the light attachment process in the home controller 100 according to the present embodiment will be described. FIG. 5 is a flowchart showing the processing procedure of the light mounting process in the home controller 100 according to the present embodiment.

  Referring to FIG. 5, CPU 110 of home controller 100 determines whether or not a new light 130 is attached to any socket (step S102). For example, the CPU 110 receives information indicating that the light 130 is newly attached from the newly attached light 130 or from the socket to which the light 130 is newly attached via the first communication interface 105. . Alternatively, the CPU 110 receives information specifying the socket to which the light 130 is attached from the user via the touch panel 106 or the button 104.

  CPU110 repeats the process of step S102, when the new light 130 is not attached (when it is NO in step S102).

  CPU110 judges whether the model number of the new light 130 was able to be acquired, when the new light 130 was attached (when it is YES in step S102) (step S104). For example, the socket identifies the new light 130 model number. The CPU 110 acquires the model number of the new light 130 from the socket via the first communication interface 105. Or CPU110 receives the model number of the light 130 newly attached from the user via the touch panel 106 or the button 104. FIG.

  CPU110 repeats the process of step S104, when the model number of the new light 130 cannot be acquired (when it is NO in step S104). In step S <b> 104, CPU 110 may display a message prompting the user to input a new light 130 model number on touch panel 106.

  CPU110 acquires the information regarding the new light 130, when the model number of the new light 130 is acquirable (when it is YES in step S104) (step S106). The information regarding the light 130 includes the life of the light 130, the color rendering properties of the light 130, the illuminance assumed to be realized by the light 130, the luminous flux of the light 130, and the like.

  For example, the CPU 110 receives information related to the light 130 from the server 300 based on the model number of the light 130 via the second communication interface. Alternatively, the memory 101 stores various information related to the light 130 in association with the model number of the light 130. Then, the CPU 110 may read out information related to the light 130 from the memory 101 based on the model number of the light 130. Alternatively, the CPU 110 may receive information regarding the light 130 from the user via the touch panel 106 or the button 104.

  The CPU 110 resets the integrated power consumption corresponding to the target light 130 in the light table 101A. Based on the information on the new light 130, the CPU 110 updates the color rendering properties corresponding to the target light 130 in the light table 101A.

  The CPU 110 determines whether or not the color rendering properties of the light 130 are greater than or equal to a predetermined value (step S108). When the color rendering property of the light 130 is less than the predetermined value (NO in step S108), the CPU 110 allocates the light 130 to the low color rendering group (group A) (step S112). CPU110 complete | finishes a light attachment process.

  If the color rendering property of the light 130 is equal to or greater than a predetermined value (YES in step S108), the CPU 110 determines whether the required color rendering property of the place where the light 130 is attached is equal to or greater than the predetermined value (step). S110). CPU110 performs the process from step S112, when the required color rendering property of the place where the light 130 was attached is not more than a predetermined value (when it is NO in step S110).

  CPU110 allocates the light 130 to a high color-rendering group (group B), when the required color-rendering property of the place where the light 130 was attached is more than predetermined value (it is YES in step S110) (step S114). CPU110 complete | finishes a light attachment process.

Next, the light control process in the home controller 100 according to the present embodiment will be described. FIG. 6 is a flowchart showing the processing procedure of the write control processing in the home controller 100 according to the present embodiment.

  Referring to FIG. 6, CPU 110 of home controller 100 determines whether or not a command for turning on or off any one of lights 130 is input (step S202). CPU110 repeats the process from step S202, when the command for turning ON / OFF any one of lights 130 is not input (when it is NO in step S202).

  When an instruction for turning on / off any of the lights 130 is input (YES in step S202), the CPU 110 turns on / off the target light 130 based on the instruction (step S204). ). CPU 110 refers to timer 109 to obtain the current date and time (step S206). The CPU 110 refers to the daytime table 101B and determines whether or not the present daytime is present (step S208).

  If it is daytime (YES in step S208), CPU 110 executes daytime processing (step S300). When the daytime process is completed, CPU 110 repeats the process from step S202.

  If it is nighttime (NO in step S208), CPU 110 executes nighttime processing (step S400). When the night process ends, CPU 110 repeats the process from step S202.

(Daytime processing)
Next, daytime processing in the home controller 100 according to the present embodiment will be described. FIG. 7 is a flowchart showing a processing procedure of daytime processing in home controller 100 according to the present embodiment.

  Referring to FIG. 7, CPU 110 of home controller 100 assigns 1 to variable n of memory 101 (step S302). The number of the plurality of lights 130 </ b> A to 130 </ b> F is registered in advance in the memory 101 as the variable N.

  CPU 110 determines whether n-th light 130 is lit or not (step S304). CPU110 acquires illumination intensity from the illumination intensity sensor 120 corresponding to the nth light 130, when the nth light 130 is lighting (when it is YES in step S304). CPU110 reads the required illumination intensity corresponding to the nth light 130 from the light table 101A.

  CPU110 judges whether the illumination intensity from the illumination intensity sensor 120 corresponding to the nth light 130 is higher than required illumination intensity (step S306). If the illuminance from the illuminance sensor 120 is higher than the required illuminance (YES in step S306), the CPU 110 decreases the illuminance of the nth light by one step (step S308). CPU110 repeats the process from step S306.

  CPU 110 determines the variable when n-th light 130 is not lit (NO in step S310), and when the illuminance from illuminance sensor 120 is lower than the required illuminance (NO in step S306). n is incremented (step S310). In the present embodiment, it is assumed that when the light 130 is turned on, the light 130 is lit at the maximum intensity. When the user feels that the light 130 is much darker than the necessary illuminance, the user can realize the illuminance close to the necessary illuminance by attaching the light 130 again.

  However, in step S306 and step S308, the CPU 110 sets the nth value so that the illuminance from the illuminance sensor 120 is closest to the required illuminance, or the illuminance from the illuminance sensor 120 is the lowest value above the required illuminance. It is preferable that the intensity of the light 130 can be adjusted.

  CPU 110 determines whether or not variable n = N (step S312). CPU110 repeats the process from step S304, when it is not n = N (when it is NO in step S312). CPU110 complete | finishes a daytime process, when it is n = N (when it is YES in step S312).

(Night processing)
Next, night processing in the home controller 100 according to the present embodiment will be described. FIG. 8 is a flowchart showing a processing procedure of night processing in the home controller 100 according to the present embodiment.

  Referring to FIG. 8, CPU 110 of home controller 100 assigns 1 to variable m of memory 101 (step S402). In advance, the number of a plurality of groups is registered as a variable M in the memory 101.

  The CPU 110 reads the accumulated power consumption of each of the plurality of lights 130A to 130D belonging to the mth group from the light table 101A (step S404). CPU110 determines the ratio of the light intensity of several light 130A-130D based on each integrated power consumption of several light 130A-130D (step S406).

  In the present embodiment, CPU 110 uses third light 130C (or the third light 130C (or the second light 130B) included in the mth group with respect to the integrated power consumption of the first light 130A (or the second light 130B). The ratio of the cumulative power consumption of the fourth light 130D) is that the light intensity of the first light 130A (or the second light 130B) with respect to the light intensity of the third light 130C (or the fourth light 130D). The ratio of the light intensity of the plurality of lights 130A to 130D is determined so as to be equal to the ratio.

  However, the CPU 110 includes the third light 130C (or the fourth light 130D) in which the accumulated power consumption of the first light 130A (or the second light 130B) included in the mth group is included in the mth group. ) Is smaller than the integrated power consumption, the light intensity of the first light 130A (or the second light 130B) is larger than the light intensity of the third light 130C (or the fourth light 130D). It will be good.

  The CPU 110 reduces the illuminance from the corresponding plurality of illuminance sensors 120 </ b> A to 120 </ b> D to the necessary illuminance while maintaining the determined light intensity ratios of the plurality of lights 130 </ b> A to 130 </ b> D via the first communication interface 105. Until then, the light intensity of the plurality of lights 130A to 130D belonging to the mth group is reduced (step S408).

  CPU 110 increments variable m (step S410). CPU 110 determines whether or not variable m = M (step S412). CPU110 repeats the process from step S404, when it is not m = M (when it is NO in step S412). CPU110 complete | finishes nighttime processing, when it is m = M (when it is YES in step S412).

  Thereby, in the daytime, the power consumption of the lights 130A, 130B, and 130E on the window side is larger than the power consumption of the lights 130C, 130D, and 130F on the indoor side. It can be made uniform. That is, it is possible to make the integrated power consumption of the plurality of lights more uniform than in the past while considering the light intensity required for each of the plurality of lights.

[Embodiment 2]
Next, a second embodiment of the present invention will be described. In the network system 1 according to Embodiment 1 described above, the home controller 100 controls the light intensities of the lights 130A to 130F based on the illuminance from the illuminance sensor 120 during the daytime. On the other hand, in the network system 1 according to the present embodiment, the light intensity (power consumption) of the lights 130A, 130B, 130E arranged on the window side and the lights 130C, 130D, A ratio with the intensity (power consumption) of 130F is set.

  Specifically, in the network system 1 according to the present embodiment, the light intensity of the lights 130A, 130B, and 130E arranged on the window side during the daytime is the light of the lights 130C, 130D, and 130F arranged on the indoor side. It becomes smaller than the strength of. In other words, the illuminance sensor 120 is not necessary in the present embodiment.

  Hereinafter, the description of the same configuration as that of network system 1 according to Embodiment 1 will not be repeated.

  First, the overall configuration of the network system according to the present embodiment will be described. FIG. 9 is an image diagram showing an overall configuration of network system 1 according to the present embodiment. Referring to FIG. 9, the present embodiment is different from the first embodiment in that network system 1 does not include a plurality of illuminance sensors 120A to 120F. Since other configurations are the same as those of the first embodiment, description thereof will not be repeated here.

  Next, the hardware configuration (FIG. 2) of the network system 1 will be described. In the present embodiment, the data stored in the memory 101 and the specific operation of the CPU 110 are different from those in the first embodiment. Hereinafter, data stored in the memory 101 and specific operations of the CPU 110 will be described. Since other configurations are the same as those of the first embodiment, description thereof will not be repeated here.

  The memory 101 according to the present embodiment includes a control program executed by the CPU 110, a plurality of lights 130A to 130F, or a light table 101C indicating information on installation locations (sockets) of the plurality of lights 130A to 130F, daytime and period, The daytime table 101B indicating the correspondence relationship is stored. Hereinafter, the write table 101C stored in the memory 101 will be described. Since daytime table 101B is the same as that of the first embodiment, description thereof will not be repeated here.

  FIG. 10 is an image diagram showing a light table 101C according to the present embodiment. Referring to FIG. 10, the light table 101 </ b> C needs to correspond to the integrated power consumption of the currently installed light 130, the daytime light intensity required for the light 130, and the light 130 for each installation location of the light 130. The color rendering properties, the group to which the light 130 belongs, information for specifying the illuminance sensor 120 corresponding to the light 130, the life of the light 130, and the like are included.

  The information on the accumulated power consumption is for specifying a value (usage amount) obtained by integrating the power consumption of the light 130 with the usage time with respect to the target light 130. The CPU 110 updates the accumulated power consumption of the light 130 based on data from the light 130 and the socket. For example, the CPU 110 receives information indicating that the light intensity has changed and the latest power consumption from the light 130 or the socket via the first communication interface 105. CPU 110 refers to timer 109 to update the accumulated power consumption.

  The daytime light intensity information is used to specify whether the daylight light intensity of the target light 130 should be stronger, the same, or weaker than the daylight light intensity of the other lights 130. belongs to. In the present embodiment, the light intensity is set in two stages. More specifically, the CPU 110 lights the light 130 corresponding to “strong” with the maximum output in the daytime. The CPU 110 lights the light 130 corresponding to “weak” at 50% of the maximum output during the daytime.

  In the present embodiment, the light intensities of the plurality of lights 130A to 130F are set in two steps, but may be set in a plurality of steps or substantially in a stepless manner. For example, the light intensity may be set in three stages. In this case, the CPU 110 lights the light 130 corresponding to “strong” with the maximum output during the daytime. The CPU 110 turns on the light 130 corresponding to “medium” at 2/3 of the maximum output in the daytime. The CPU 110 lights the light 130 corresponding to “small” at 1/3 of the maximum output during the daytime.

  The information on the color rendering properties of the light 130 is for specifying the color rendering properties of the target light 130. As for the color rendering, when the light 130 is installed, the CPU 110 acquires the model number (type) of the light 130 automatically or from the user via the touch panel 106. The CPU 110 acquires the color rendering properties corresponding to the light 130 from the server 300 based on the type of the target light 130 via the second communication interface 107. Alternatively, when the target light 130 is used for the first time, the user may set the color rendering properties via the touch panel 106.

  The necessary color rendering properties information is for specifying the color rendering properties required at the place where the light 130 is installed. The user can set a preferable value for the target installation location as the required color rendering properties. That is, the CPU 110 may receive the necessary color rendering properties for each installation location from the user via the touch panel 106.

  The group information is for specifying the group to which the light 130 belongs. In the present embodiment, home controller 100 equalizes the integrated power consumption of lights 130 for each group. For example, a plurality of sockets 130 to which a plurality of lights 130 having a high color rendering property or a light 130 having a high color rendering property are attached are allocated to the same group. Alternatively, a plurality of sockets to which a plurality of lights 130 having a large luminous flux or a light 130 having a large luminous flux should be attached are allocated to the same group. Alternatively, a plurality of sockets to which a plurality of lights 130 having a maximum maximum power consumption or a light 130 having a maximum maximum power consumption should be attached are allocated to the same group.

  The CPU 110 refers to the daytime table 101B and determines whether it is daytime or nighttime based on the time from the timer 109.

  The CPU 110 refers to the light table 101C, and in the daytime, the light intensity (consumption) of the first light 130A, the second light 130B, and the fifth light 130E arranged on the window side (a relatively bright area in the daytime). (Power) is set to be smaller than the light intensity (power consumption) of the third light 130C, the fourth light 130D, and the sixth light 130F arranged indoors (in a relatively dark area in the daytime). To do.

  As described above, in the present embodiment, the CPU 110 determines the light intensity of the lights 130A, 130B, and 130E corresponding to “weak” of the light table 101C and the light 130C, corresponding to “strong” of the light table 101C. The plurality of lights 130 </ b> A to 130 </ b> F are controlled via the first communication interface 105 so that the intensity of light of 130 </ b> D and 130 </ b> F becomes 1 to 2.

  As a result, the amount of power consumed by the lights 130A, 130B, and 130E on the window side can be reduced by effectively using sunlight during the daytime. Therefore, during the daytime, the amount of increase in the accumulated power consumption of the window-side lights 130A, 130B, 130E is smaller than the amount of increase in the accumulated power consumption of the indoor-side lights 130C, 130D, 130F.

  At night, the CPU 110 determines the light of the first light 130A, the second light 130B, and the fifth light 130E arranged on the window side (a relatively bright area during the day) based on the magnitude of the accumulated power consumption. The first communication interface so that the intensity is higher than the intensity of light of the third light 130C, the fourth light 130D, and the sixth light 130F arranged on the indoor side (a relatively dark area in the daytime). The plurality of lights 130 </ b> A to 130 </ b> F are controlled via 105.

  In the present embodiment, the CPU 110 receives the first light close to the window from the plurality of lights 130A to 130F via the button 104 or the touch panel 106. And a command for selecting a second light far from the window (light that weakens the intensity at night) from among the plurality of lights 130A to 130F. In other words, the CPU 110 may accept a command for setting whether each of the plurality of lights 130A to 130F is the first light or the second light.

  However, a plurality of illuminance sensors 120A to 120F as described in the first embodiment may be used for setting the first light and the second light. That is, the CPU 110 acquires illuminance from the plurality of illuminance sensors 120A to 120F via the first communication interface 105 when the plurality of lights 130A to 130F are turned off during the daytime. The CPU 110 sets the area where the illuminance sensors 120A, 120B, 120E with high illuminance are arranged as the first area (a relatively bright area in the daytime), and arranges the illuminance sensors 120C, 120D, 120F with lower illuminance. The set area is set as a second area (a relatively dark area in the daytime). Alternatively, the CPU 110 sets the lights 130A, 130B, and 130E corresponding to the illuminance sensors 120A, 120B, and 120E having high illuminance to the first light (light that weakens the intensity during the day and increases the intensity at the night), and the illuminance is low. The lights 130C, 130D, and 130F corresponding to the illuminance sensors 120C, 120D, and 120F are set as the second lights (lights that reduce the intensity at night).

  Thereby, in the network system 1 according to the present embodiment, it is possible to make the integrated power consumption of the plurality of lights more uniform than in the past while considering the light intensity required for each of the plurality of lights.

  CPU110 receives the intensity | strength in the daytime of the light 130 newly attached from the user via the touch panel 106 or the button 104 (step S116). Based on the received intensity, the CPU 110 updates the daytime intensity information of the light 130 that is the target of the light table 101C (step S118). CPU110 complete | finishes a light attachment process.

  However, in the light table 101C, the light intensity of the light 130 corresponding to the socket at the south facing window is set to “high” in advance, and the light corresponding to the socket at the window facing in the other direction and the socket on the indoor side facing south. The light intensity of the light 130 corresponding to the indoor socket in the other direction may be set to “low”. That is, it is possible not to execute steps S116 and S118.

Lights 130A to 130F are turned on.

  When a command for changing the intensity of any of the plurality of lights 130A to 130F is input, the CPU 110 may prioritize the command. Alternatively, the CPU 110 determines the ratio of the daytime light intensity of the light table 101C (the intensity of the first light 130A: the intensity of the second light 130B: the intensity of the third light 130C: the intensity of the fourth light 130D: 5 light 130E intensity: sixth light 130F intensity = 1: 1: 2: 2: 1: 2) while maintaining the intensity of the lights 130A to 130F based on the command. Also good.

The light intensities of the plurality of lights 130A to 130D are determined so as to be equal to the above ratio.

  However, the CPU 110 includes the third light 130C (or the fourth light 130D) in which the accumulated power consumption of the first light 130A (or the second light 130B) included in the mth group is included in the mth group. ) Is smaller than the integrated power consumption, the light intensity of the first light 130A (or the second light 130B) is larger than the light intensity of the third light 130C (or the fourth light 130D). It will be good.

  The CPU 110 transmits a command for turning on the lights 130A to 130D with the determined light intensity via the first communication interface 105 (step S409).

  CPU 110 increments variable m (step S410). CPU 110 determines whether or not variable m = M (step S412). CPU110 repeats the process from step S404, when it is not m = M (when it is NO in step S412). CPU110 complete | finishes nighttime processing, when it is m = M (when it is YES in step S412).
