Description

  The present invention relates to a lighting pattern setting device and a program, and more particularly to a simulation for achieving a predetermined target by thinning out lighting fixtures installed in a room.

  In order to save energy, etc., it is common practice to thin out the lighting fixtures by turning off some of the lighting fixtures installed in the room. Which lighting fixtures should be turned off to reduce power consumption has generally been relied on by the practitioners who take countermeasures based on experience and sense. In recent years, control systems for realizing desired illuminance by adjusting the illuminance of each of a plurality of lighting fixtures have been proposed (for example, Patent Documents 1 and 2).

  By the way, there is an opposite island type office layout style in which islands are formed by connecting desks facing each other in organizational units such as company departments and sections. In many cases, each island is provided in a large room without partitioning.

  Further, when the lighting pattern setting means divides the area into a plurality of small areas corresponding to the installation positions of the lighting fixtures in the area, the average illuminance of the illuminance in the small areas or the small areas A lighting pattern that achieves a predetermined target of setting the maximum illuminance to a predetermined threshold value or less is set.

  Further, the lighting pattern setting means sets a lighting pattern in which the reduction amount of power used in the entire room is equal to or greater than a predetermined target value.

  The program according to the present invention is a computer that accepts a computer that is designated by a user and receives a region of a part of a room in which a plurality of lighting fixtures are installed, by turning on or off each of the plurality of lighting fixtures installed in the region. This is a lighting pattern for functioning as lighting pattern setting means for setting a lighting pattern in which the illuminance in the region achieves a predetermined target, and output means for outputting the set lighting pattern.

Embodiment 1 FIG.
FIG. 1 is a block configuration diagram showing an embodiment of a lighting pattern setting device according to the present invention. FIG. 2 is a hardware configuration diagram of a computer forming the lighting pattern setting device 10 according to the present embodiment. In the present embodiment, the computer forming the lighting pattern setting device 10 can be realized by a general-purpose hardware configuration such as a personal computer (PC). That is, as shown in FIG. 2, the lighting pattern setting device 10 includes a CPU 21, ROM 22, RAM 23, hard disk drive (HDD) 24, a mouse 25 and a keyboard 26 provided as input means, and a display 27 provided as a display device. Are connected to an internal bus 30 and an input / output controller 28 for connecting to each other and a network controller 29 provided as a communication means.

  Returning to FIG. 1, the lighting pattern setting device 10 in this embodiment includes an information receiving unit 11, a simulation screen display processing unit 12, a simulation execution unit 13, a control unit 14, a simulation setting information storage unit 16, and a simulation result storage unit 17. have. In the present embodiment, a simulation for thinning out lighting fixtures is executed as will be described later. However, the information receiving unit 11 receives information necessary for executing a simulation transmitted from an external system or input manually. Are registered in the simulation setting information storage unit 16 as simulation setting information. The simulation setting information includes information on the room, information on the lighting fixture, and information on the power usage of the lighting fixture. Information on the room includes the size of the room, the interior color, the arrangement of the lighting fixtures installed in the room, the number of horizontal lighting units, the number of vertical lighting units, the height of the desk-ceiling, the height of the horizontal lighting units, and the vertical Information such as the direction lighting unit interval is included. The information related to the lighting fixture includes information such as the installation method such as the embedded type, the lighting unit type of the lighting fixture, the number of fluorescent lamps, the fluorescent lamp type, and the luminous intensity characteristics. The information related to the power usage of the lighting fixture includes information such as an electricity bill per 1 [w], power consumption per lighting unit, and a maintenance rate indicating how dirty or deteriorated the lighting fixture is. By referring to these simulation setting information, the illuminance can be calculated more accurately in executing the simulation, and the electric energy used by the luminaire can be calculated with high accuracy. Of course, the information is not limited to the above information, and further includes information for improving the accuracy of the simulation described later, such as coefficients considering external light and reflection based on the number and size of the windows, the material of the wall, and the like. You may do it.

  The simulation screen display processing unit 12 executes display processing of a simulation screen displayed on the display 27 when executing the simulation. Furthermore, the simulation screen display processing unit 12 also functions as a reception unit that receives a partial area (hereinafter, also referred to as “specific area”) of a room in which a plurality of lighting fixtures are specified, which is designated by a simulation executor. .

  The simulation execution unit 13 determines the lighting pattern of the luminaire that should achieve a predetermined target based on the setting contents of the simulation setting information registered in the simulation setting information storage unit 16 in accordance with an execution instruction from the simulation executor. Run the simulation you are looking for. A lighting pattern is a pattern formed when each of a plurality of lighting fixtures is turned on or off. The thinning out of lighting fixtures is carried out for the basic purpose of energy saving, but considering the comfort and comfort of the room, the minimum illuminance should be secured according to the room. In the present embodiment, the minimum illuminance required in the room is set as a predetermined target. The specific area simulation execution unit 131 included in the simulation execution unit 13 is provided as a lighting pattern setting unit, and a plurality of the specific area simulation execution units 131 installed in the specific area received by the simulation screen display processing unit 12 by executing the simulation in the specific area. The lighting pattern is set by the lighting fixtures, and the lighting pattern in which the illuminance in the area achieves a predetermined target is set. The control unit 14 operates in cooperation with the other components 11 to 13 to control the execution of the simulation in the lighting pattern setting device 10.

  The simulation setting information storage unit 16 stores simulation setting information acquired by the information receiving unit 11. The simulation result accumulation unit 17 accumulates the simulation execution result by the simulation execution unit 13.

  The constituent elements 11 to 14 in the lighting pattern setting device 10 are realized by a cooperative operation of a computer that forms the lighting pattern setting device 10 and a program that operates on the CPU 21 mounted on the computer. The storage units 16 and 17 are realized by the HDD 24 mounted on the lighting pattern setting device 10. Alternatively, the RAM 23 or an external storage means may be used via a network.

  Further, the program used in this embodiment can be provided not only by communication means but also by storing it in a computer-readable recording medium such as a CD-ROM or USB memory. The program provided from the communication means or the recording medium is installed in the computer, and various processes are realized by the CPU of the computer sequentially executing the program.

  FIG. 3 is a diagram showing an example of a simulation screen displayed on the display 27 when the simulation is executed in the present embodiment. The simulation execution result is displayed on the simulation screen. In addition, information other than that illustrated in FIG. 3, such as energy saving effect when lighting fixtures are thinned out and simulation setting information registered in the simulation setting information storage unit 16 are displayed in an editable manner. Although it may be displayed, such information is not used in the description of the present embodiment, and is omitted.

  By the way, thinning out the luminaire means turning off the lit luminaire and turning it off. In the simulation in the present embodiment, when the “decimate one” button 31 is pressed, the illuminance is measured every time one of the lighting fixtures installed in the room is turned off one by one from the lighting state. Is executed until one lighting fixture is finally left. Further, after the target illuminance is set in the illuminance designation area 33, when the “thinning by illuminance designation” button 32 is pressed, basically the same as when the “thinning out one” button 31 is pressed. Execute the process. However, when the “decimate one” button 31 is pressed, the thinning process is always executed until the remaining one is reduced, whereas when the “decimate by illuminance designation” button 32 is pressed, the illuminance designation is performed. Thinning-out processing is executed until just before the illuminance set in the region 33 falls below. The “return to initial setting” button 34 is a button for returning to an initial state in which all the lighting fixtures installed in the room are lit.

  In the present embodiment, information obtained during the execution of the simulation, that is, information obtained until the simulation process is completed from the state in which all the lights are lit is handled as the “simulation result”. For example, when 10 lighting fixtures are installed in a room, a simulation result in a state where 1 to 9 lighting fixtures are thinned out is also recorded each time.

  In the present embodiment, the room is divided into rectangular regions corresponding to the installation positions of the lighting fixtures. The lighting pattern display area 35 in FIG. 3 shows the arrangement of lighting fixtures installed in the room and the lighting pattern of the lighting fixtures, that is, whether each lighting fixture is on or off. In the present embodiment, for the sake of convenience, the lighting fixtures are arranged vertically and horizontally on the ceiling of the room. Therefore, the lighting pattern display area 35 includes the horizontal illumination included in the simulation setting information. With reference to the number of units and the number of vertical illumination units, rectangles indicating the respective lighting fixtures are displayed in alignment. The lighting fixtures that are turned on are displayed in a relatively bright color, and the lighting fixtures that are turned off are displayed in a relatively dark color, so that it is possible to easily recognize whether the lighting is turned on or off. Of course, the difference between lighting and extinguishing may be expressed not by the brightness of the color but by the color scheme or decoration. FIG. 5B is an enlarged view of the region A in FIG. 5A, but the turn-off order is displayed in the rectangle 42 corresponding to the light-off lighting fixture as illustrated in FIG. 5B.

  In the illuminance value display area 36, the illuminance [lx] measured at the position of the area corresponding to each lighting fixture in the lighting pattern shown in the lighting pattern display area 35 is indicated by a numerical value.

  Next, simulation processing executed by the simulation execution unit 13 in the present embodiment will be described with reference to the flowchart shown in FIG. Here, a case where a lighting fixture is thinned out to a designated illuminance will be described.

  As described above, the room is divided into areas corresponding to the installation positions of the respective lighting fixtures. After the simulation executor sets the target illuminance in the illuminance designation area 33 on the simulation screen, the simulation is started by pressing the “thinning by illuminance designation” button 32. At the start of the simulation, all the luminaires are turned on as shown in FIG. 3 in the same manner as after the “return to initial setting” button 34 is pressed. When the “thinning by illuminance designation” button 32 is pressed, the simulation execution unit 13 calculates the illuminance in each area of the room in this state (step 101). The illuminance of each region can be calculated by a known calculation method called a point-by-point method based on information on the room and the lighting fixture. The illuminance of each area when all the luminaires are lit is calculated in advance as an initial state when the simulation screen is displayed on the display 27 and displayed in the illuminance value display area 36. Good.

  The simulation execution unit 13 identifies the region with the highest illuminance among the calculated illuminances (step 102). And the lighting fixture located nearest to the area | region of the specified illumination intensity is specified. Basically, the luminaire installed in the area corresponds to this, but the simulation execution unit 13 turns off the identified luminaire (step 103). In addition, since the lighting fixture is not actually turned off, the lighting fixture is accurately specified as a target to be turned off in the simulation. Subsequently, the simulation execution unit 13 calculates the illuminance in each region again by turning off the light (step 104). And the simulation result currently displayed on the simulation screen is each updated according to the light extinction of one lighting fixture (step 105).

  In other words, the simulation execution unit 13 changes the rectangle corresponding to the light fixture that has been turned off in the lighting pattern display area 35 to a display form that is turned off. In addition, like the rectangle 37 shown in FIG. 5B, the display form of the rectangle corresponding to the light fixture that has been turned off is displayed in a different display form from the rectangle that corresponds to the lighting fixture that is already turned off. It may be displayed so that it is possible to grasp at a glance that the lighting apparatus is thinned out this time. In addition, the simulation execution unit 13 updates the illuminance value displayed in the illuminance value display area 36 with the illuminance value recalculated after the light is turned off. The simulation execution unit 13 updates the display content of the simulation screen with the simulation result such as the illuminance value of each region obtained by turning off one lighting fixture as described above, and also stores the simulation content in the simulation result storage unit 17. Record (step 106).

  Subsequently, the simulation execution unit 13 calculates the illuminance in each region when one further thinning is performed by performing the processing performed in steps 102 to 104, and obtains the average illuminance (step 107). In addition, since the calculation result when one further thinning is performed is not reflected or recorded in the display, this process is referred to as “temporary thinning”.

  The simulation execution unit 13 determines whether or not the average illuminance of the entire room obtained by the temporary thinning is lower than the illuminance specified in the illuminance designation area 33. If the average illuminance of the entire room does not fall below the specified illuminance (N in step 108), the process returns to step 102 and the above-described processing is executed. At this time, since the processing of steps 102 to 104 has already been performed at the time of temporary thinning, the processing result may be used effectively.

  On the other hand, when the average illuminance of the entire room obtained by temporary thinning is lower than the specified illuminance (Y in step 108), the lowest illuminance among the illuminances that is equal to or higher than the illuminance specified in the illuminance specification area 33 is obtained. At this point, the thinning process ends.

  A lighting pattern that achieves a predetermined target can be obtained by executing the above simulation processing. According to the setting example of the target illuminance (650 [lx]) shown in FIG. 3, the luminaire is thinned out most when the illuminance of the entire room is 650 [lx] or more and the illuminance is 650 [lx] or more. As a result, a lighting pattern with the highest energy saving effect can be obtained. FIG. 5A shows a display example of the simulation screen after the simulation is executed when the illuminance is designated. FIG. 5A is a display example of a simulation screen when 15 lighting fixtures are thinned out as a result.

  In the present embodiment, the average illuminance of the entire room is used when obtaining a lighting pattern that achieves a predetermined target. However, the present invention is not limited to this. For example, the minimum illuminance required in the room may be used.

  The simulation executed when the “decimation by illuminance designation” button 32 is pressed is as described above, but the simulation executed when the “decimate one” button 38 is pressed does not require step 107. The branching conditions in step 108 are different. That is, instead of repeating until just below the specified illuminance, thinning out the lighting fixtures may be repeated until there is only one remaining lighting fixture. The simulation executed when the “thinning out one” button 38 is pressed is, for example, a patent application including the same applicant as the present application (Japanese Patent Application No. 2012-062034, title of invention: “lighting lighting pattern setting device and The same simulation as described in “Method”) may be performed.

  By the way, it is assumed that seats are arranged in an office layout style called an opposed island type in a room. In the above-described simulation, it may be possible to thin out lighting fixtures that can be expected to save energy for the entire room. However, when the seats are arranged in the opposite island type for each department, a bright seat and a dark seat may be mixed in the same department. For the same department (island), it is preferable that the luminaire can be thinned out so that the illuminance is uniform.

  Therefore, the present embodiment is characterized in that the luminaires in the specific area are thinned out so that the illuminance in the entire partial area (specific area) of the room is uniform. Hereinafter, the specific area simulation process performed only in the specific area according to the present embodiment will be described with reference to the flowchart shown in FIG. Note that this process may be started by a button operation (not shown) or the like by a simulation executor.

  First, the executor of the simulation performs, for example, an area designation operation such as a drag operation on the lighting pattern display area 35 of the simulation screen using the mouse 25, thereby specifying the specific area 38 as shown by a rectangle in FIG. Is specified. As illustrated in FIG. 7, the simulation screen display processing unit 12 displays a rectangle 39 surrounding the illuminance value corresponding to the specific area 38 in the illuminance value display area 36 in conjunction with the area designation operation. Also good. Alternatively, the specific area 38 may be set in the lighting pattern display area 35 by setting a rectangle 39 in the illuminance value display area 36. Alternatively, the specific area 38 may be easily designated by superimposing the seat layout in the room on the lighting pattern display area 35.

  When the specific area simulation execution unit 131 acquires the specified specific area 38 (step 111), the specific area simulation execution unit 131 specifies the maximum illuminance and the minimum illuminance from the illuminance values of each area (small area) included in the specific area 38, and The difference is calculated (step 112). If the difference is less than the threshold value N1 set by the person executing the simulation (N in step 113), it is determined that the illuminance in the specific area is uniform and uniform, and the process ends. The threshold value N1 may be specified at the start of the specific area simulation process. Further, an initial value may be set in advance in the lighting pattern setting device 10.

  On the other hand, if the difference between the maximum illuminance and the minimum illuminance is greater than or equal to the threshold value N1 (Y in step 113), the specific area simulation execution unit 131 causes the executor of the simulation to turn on all the luminaires in the specific area 38. Alternatively, the processing described later is continued from the current lighting pattern, that is, the initial state of the lighting pattern of the specific area 38 in the specific area simulation processing is inquired. This may be inquired by displaying another window screen on the simulation screen or on the display 27.

  When the simulation executor selects and instructs to turn on all the lighting fixtures once (Y in Step 114), the specific area simulation execution unit 131 turns on all the lighting fixtures in the specific area 38 (Step 115). ), The illuminance of each region in the specific area 38 in that state is calculated (step 116). If it is selected and instructed to continue thinning from the current lighting pattern (N in step 114), no processing is performed and the process proceeds to step 117. FIG. 8A is a diagram in which only the specific area 38 in FIG. 7 is extracted. FIG. 8B shows a lighting pattern of the specific area 38 when all lighting is selected.

  Subsequently, the specific area simulation execution unit 131 executes a process of thinning out the lighting apparatus having the highest illuminance from the lighting state according to the current lighting pattern (step 117). This process is the same as steps 102 to 106 in which the illuminance is calculated after thinning out one lighting fixture in the simulation process in the entire room, and the screen display and recording of the state after the thinning is performed. .

  Then, this thinning-out process is repeatedly executed until the difference between the maximum illuminance and the minimum illuminance of each region in the specific area 38 after thinning is below the threshold value N1 (N in step 118). When the difference between the maximum illuminance and the minimum illuminance falls below the threshold value N1 (Y in step 118), it is determined that the illuminance in the entire specific area 38 is uniform at this point. As is clear from the above description, the lighting state in which the difference between the maximum illuminance and the minimum illuminance is less than the threshold value N1 is equivalent to the state where the illuminance in the entire specific area 38 is uniform.

  By the way, even if the illuminance in the entire specific area 38 becomes uniform, the person who performs the simulation wants to reduce the illuminance in the entire specific area 38 by thinning out the luminaires in the specific area 38 from the viewpoint of energy saving. You may want to increase the effect.

  Therefore, in the present embodiment, even if the predetermined target that the difference between the maximum illuminance and the minimum illuminance of each region in the specific area 38 is less than the threshold value N1 is achieved, the decimation can be continued further. That is, when the difference between the maximum illuminance and the minimum illuminance falls below the threshold value (Y in step 118), the specific area simulation execution unit 131 continues to thin out the lighting fixtures in the specific area 38 to the simulation executor. Or ask. This may be inquired by displaying another window screen on the simulation screen or on the display 27.

  When the person who performs the simulation selects and instructs to continue (Y in step 119), the specific area simulation execution unit 131 repeatedly executes the above-described processing (steps 117 to 118). When it is selected and instructed not to continue (N in step 119), the process is terminated. In the present embodiment, even when a lighting pattern that achieves a predetermined target is obtained in this way, it is possible to search for a lighting pattern with a higher energy saving effect by further repeating the thinning process. A lighting pattern that achieves a predetermined target with a higher energy saving effect than the lighting pattern obtained at this time can be called an “optimal solution”.

  FIG. 8C shows an example of the lighting pattern obtained when the specific area simulation is continuously executed from the lighting pattern obtained by the simulation execution of the entire room shown in FIG. 4 shows examples of lighting patterns obtained when the specific area simulation is executed after all the lighting fixtures in the specific area 38 are turned on after the simulation of the entire room shown in FIG.

  According to the present embodiment, the lighting pattern that achieves the predetermined target of suppressing the difference between the maximum illuminance and the minimum illuminance in the specific area 38 to be less than the threshold is searched, and the lighting pattern is installed in the specific area 38. By setting each lighting fixture to be turned on or off, the illuminance variation (illuminance unevenness) in the specific area 38 can be eliminated. As a result, dissatisfaction and unfairness with respect to variations in illuminance within the same island can be prevented.

Embodiment 2. FIG.
In the first embodiment, variation in illuminance in the specific area 38 is eliminated by suppressing the difference between the maximum illuminance and the minimum illuminance of the area in the specific area 38. The present embodiment is characterized in that variation in illuminance is eliminated in the specific area 38 by suppressing the difference in illuminance between adjacent regions.

  The configuration in the present embodiment and the simulation process in the entire room may be the same as in the first embodiment, and the specific area simulation process shown in FIG. 6 is slightly different from that in the first embodiment.

  Hereinafter, the specific area simulation processing in the present embodiment will be described with reference to the flowchart shown in FIG. Note that the same processes as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted as appropriate. In addition, the application examples and modifications described in the first embodiment, such as the threshold designation method, can also be applied to the present embodiment. The same applies to the embodiments described below.

  When the specific area simulation execution unit 131 acquires the specified specific area 38 (step 111), the specific area simulation execution unit 131 calculates the difference in illuminance between each of the lighting fixtures in the specific area 38 and the adjacent lighting fixture (step 211). If all the calculated illuminance differences are less than the threshold value N2 set by the person executing the simulation (N in step 212), it is determined that there is no variation in illuminance in the specific area 38, and the process ends. To do.

  On the other hand, if even one illuminance difference is greater than or equal to the threshold value N2 (Y in step 212), the specific area simulation execution unit 131 displays the lighting pattern (the lighting pattern in the fully lit state or the entire room in the room). From the lighting pattern obtained by the simulation execution (steps 114 to 116), until all the illuminance differences do not reach the threshold value N2 (Y in step 213), thinning out the lighting fixtures in the specific area 38 one by one Is repeated (N in steps 117 and 213).

  According to the present embodiment, a lighting pattern that achieves a predetermined target of suppressing the difference in illuminance between adjacent lighting fixtures in a specific area to be less than a threshold value N2 is installed in the specific area with the lighting pattern. By setting each lighting fixture to be on or off, it is possible to eliminate variations in illuminance (illuminance unevenness) in a specific area. As a result, dissatisfaction and unfairness with respect to variations in illuminance within the same island can be prevented.

Embodiment 3 FIG.
The simulation in the simulation execution unit 13 achieves energy saving in the entire room by thinning out the lighting fixtures. In the first and second embodiments, after trying to realize energy saving in the entire room, a predetermined target related to the illuminance relationship in a region (small region) included in the specific area (in the first embodiment, each small region). Variation of illuminance in a specific area by setting a lighting pattern that achieves a difference between the maximum illuminance and the minimum illuminance below the threshold in Embodiment 2, and the difference between the illuminances of adjacent small regions in the second embodiment is less than the threshold) Was made to disappear.

  The present embodiment is characterized in that the illuminance in the entire specific area can be maintained even at some sacrifice of energy saving in the entire room. This embodiment is effective when, for example, it is desired to secure a certain level of illuminance only in a specific area provided in a part of the room such as a guest room or a conference room provided in one corner of the room.

  The configuration in the present embodiment and the simulation process in the entire room may be the same as in the first embodiment, and the specific area simulation process shown in FIG. 6 is different from that in the first embodiment.

  Hereinafter, the specific area simulation processing in the present embodiment will be described with reference to the flowchart shown in FIG. Note that the same processes as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  When the specific area simulation execution unit 131 acquires the specified specific area 38 (step 111), the specific area simulation execution unit 131 calculates the average illuminance in the specific area 38 (step 311). If the average illuminance is greater than or equal to the threshold N3 set by the person performing the simulation (Y in step 312), the illuminance in the specific area is greater than or equal to a certain illuminance (threshold N3), and processing is performed. finish. The threshold value N3 needs to be a value smaller than the average illuminance when all of the lighting fixtures in the specific area 38 are turned on.

  On the other hand, when the average illuminance is lower than the threshold value N3 (N in Step 312), the specific area simulation execution unit 131 turns on all of the luminaires in the specific area 38 (Step 115) and specifies in that state. The illuminance of each area in the area 38 is calculated (step 116).

  Subsequently, the specific area simulation execution unit 131 executes a process of thinning out the lighting apparatus having the highest illuminance from the lighting state according to the current lighting pattern (step 117). Then, provisional thinning processing is performed to turn off the luminaire with the highest illuminance from the lighting state with the lighting pattern after thinning (step 313).

  Then, the specific area simulation execution unit 131 calculates the average illuminance of the specific area 38 in the temporarily thinned lighting pattern (step 314). When the average illuminance is not less than the threshold value N3 (N in step 315), the process returns to step 117, and the above-described processing is repeatedly executed. On the other hand, when the average illuminance at the time of temporary thinning is less than the threshold value N3 (Y in step 315), the process ends. That is, the lighting fixtures in the specific area 38 are thinned out one by one from the state in which they are all lit, and the lighting pattern immediately before the average illuminance in the specific area 38 falls below the threshold value is selected.

  According to the present embodiment, while the average illuminance in the specific area is set to the threshold N3 or more and energy saving is sacrificed, in the lighting pattern in which the illuminance is constant (threshold N3) or more from the entire lighting state, By searching for a lighting pattern that achieves the predetermined goal of selecting the lighting pattern with the highest energy-saving effect, and by setting each lighting fixture installed in the specific area with that lighting pattern to be on or off, in the specific area Illuminance above a certain level can be secured. In this embodiment, the average illuminance is used as an index for ensuring a certain level of illuminance, but the minimum illuminance may be used.

Embodiment 4 FIG.
In the third embodiment, the illuminance in the entire specific area is maintained even if the energy saving in the entire room is somewhat sacrificed. In the present embodiment, conversely, reduction of power consumption is emphasized, and the energy saving effect is given priority even when the illuminance in a specific area is suppressed. For example, it is effective when you want to prioritize the energy saving effect in a specific area by limiting the illuminance only for a specific area provided in a part of the room such as a regular employee area or a warehouse provided in one corner of the room. .

  The configuration in the present embodiment and the simulation process in the entire room may be the same as those in the first embodiment. Hereinafter, the specific area simulation process in the present embodiment will be described with reference to the flowchart shown in FIG. Note that the same processes as those in the third embodiment are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  The specific area simulation process in the present embodiment is basically the same as that in the third embodiment, but the condition determination based on the average illuminance is different from that in the third embodiment. That is, when the average illuminance is equal to or lower than the threshold value N4 set by the person executing the simulation (Y in step 411), the illuminance in the specific area is determined to be sufficiently lowered because the illuminance in the specific area is equal to or lower than the predetermined illuminance (threshold value N4). To finish the process.

  On the other hand, if the average illuminance exceeds the threshold N4 (N in step 411), the specific area simulation execution unit 131 thins out the average illuminance when the temporary culling is not less than the threshold N4 (N in step 412). The processing (steps 117, 313, and 314) is repeated, and when the average illuminance becomes equal to or less than the threshold value N4 (Y in step 412), the processing ends.

  According to the present embodiment, a lighting pattern that achieves a predetermined target of setting the average illuminance in a specific area to be equal to or less than a threshold value N4 that can be expected to save energy is searched, and each lighting fixture installed in the specific area with the lighting pattern By setting to ON or OFF, the illuminance in the specific area can be suppressed below a certain level. In the present embodiment, the average illuminance is used as an index for setting the illuminance below a certain level, but the minimum illuminance may be used.

Embodiment 5 FIG.
In the third and fourth embodiments, after trying to realize energy saving in the entire room, a predetermined target relating to the illuminance in the entire specific area (in the third embodiment, the illuminance in the specific area is equal to or greater than a threshold value, in the fourth embodiment) By setting a lighting pattern that achieves a predetermined target for illuminance in a specific area below a threshold value, variation in illuminance in the specific area is eliminated.

  In the present embodiment, in order to reduce power consumption in the entire room, the area where the lighting fixtures are thinned out is limited to a specific area rather than the entire room.

  The configuration in the present embodiment and the simulation process in the entire room may be the same as those in the first embodiment. Hereinafter, the specific area simulation process in the present embodiment will be described with reference to the flowchart shown in FIG. Note that the same processes as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  When the specific area simulation execution unit 131 acquires the specified specific area 38 (step 111), the specific area simulation execution unit 131 calculates the power consumption based on the lighting pattern in the entire current room, and the calculated power consumption is obtained in advance. By calculating the difference from the amount of power used in the entire room (hereinafter referred to as “the amount of power used when the room is fully lit”), the reduced power amount in the entire room is obtained (step 511).

  If the calculated power reduction amount at the present time is equal to or greater than the threshold value N5 set by the person executing the simulation (Y in step 512), it is determined that the power reduction amount in the entire room has reached the target, and the process ends.

  On the other hand, when the power reduction amount at the current time is below the threshold value N5 (N in Step 512), the specific area simulation execution unit 131 turns on all the luminaires in the specific area 38 (Step 115). Illuminance of each area in the specific area 38 is calculated (step 116).

  Subsequently, the specific area simulation execution unit 131 executes a process of thinning out the lighting apparatus having the highest illuminance from the lighting state according to the current lighting pattern (step 117). Subsequently, the specific area simulation execution unit 131 executes the process of thinning out the lighting fixtures limited to the specific area, then calculates the power consumption in the lighting pattern of the entire room, and the calculated power consumption is calculated when the room is fully lit. By subtracting from the amount of power used, the reduced power amount after thinning is obtained (step 513). When the reduced power amount is below the threshold value N5 (N in Step 514), the process returns to Step 117, and the process returns to the process of thinning out the luminaires in the specific area 38. Then, when the reduced power amount in the lighting pattern of the entire room after thinning becomes equal to or greater than the threshold value N5 (Y in step 514), the specific area simulation process is terminated.

  According to the present embodiment, a lighting pattern that achieves a predetermined target that the reduction amount of power used in the entire room is equal to or greater than a predetermined target value (threshold value N5) is limited to a specific area, and the lighting pattern is searched. By setting each lighting fixture installed in the specific area to ON or OFF, it is possible to achieve the reduced power amount set for the entire room.

  In this embodiment, in order to achieve the reduced power amount set for the entire room, the lighting apparatus is thinned out only in a specific area, but the reduced power amount is set for the specific area instead of the entire room. And in order to achieve the set reduction electric energy, you may make it thin out the lighting fixture in a specific area. In the present embodiment, the reduced power amount is set as the predetermined target value, but the used power amount may be set.
