  The lead frame 142 is a conductive thin plate used as internal wiring, and has a role of bridging with external wiring. The lens 143 collects light in order to efficiently irradiate the light from the LED chip 141. Further, silicon resin or the like is used for the encapsulating resin 144, and phosphors are dispersed.

  The LED chip 141 and the lead frame 142 are connected by wire bonding.

  The bullet-type LED is formed integrally with the lead frame 142, the LED chip 141 is mounted in the cup, the encapsulating resin 144 in which the phosphor is dispersed in the cup is encapsulated, and the periphery of the encapsulating resin 144 is made a bullet-shaped. It is formed by molding with an epoxy resin or the like.

  Since the bullet-type LED has the above-described structure, it can be a highly directional LED by increasing the light condensing property with a lens.

(Surface mount LED)
Next, another example of the type of the LED 104 will be described with reference to FIG. FIG. 4 is a diagram showing an outline of the structure of a so-called surface mount type (SMD) LED (surface mount type LED).

  As shown in FIG. 4, the surface mount LED includes an LED chip 141, an encapsulating resin 144, an electrode 145, a package substrate 146, and a reflection plate 147.

  The electrode 145 is preliminarily wired to the substrate, and constitutes a package substrate 146 together with the substrate. The reflector 147 efficiently irradiates the light from the LED chip 141.

  The LED chip 141 and the electrode 145 wired on the package substrate 146 are connected by wire bonding.

  In the surface-mounted LED, an LED chip 141 is mounted in a cavity formed of ceramic and resin, and an encapsulating resin 144 such as an epoxy resin and a silicon resin in which a phosphor is dispersed in the cavity in which the LED chip 141 is mounted. It is formed by encapsulating. The inner surface of the cavity has a function of a reflecting plate 147, and can reflect and extract and irradiate a lot of light emitted from the LED chip 141.

  A surface-mounted LED can be a highly directional LED by increasing the light condensing property with a lens, but has the above-described structure, and therefore has a characteristic that the directivity is less likely to be stronger than a bullet-type LED. There is.

  A surface-mount type LED is generally used for a ceiling light, and the ceiling light is designed so that light is diffused.

  In addition, it is preferable to use bullet-type LED with higher directivity for the illuminating device 10 which concerns on this embodiment. This is because the bullet-type LED does not disperse light, so that it is easy to control the irradiation range of the illumination device 10 when performing area driving in which only a part of the plurality of LEDs 104 included in the illumination device 10 is driven. .

[Area driving in lighting equipment]
Next, with reference to FIG.5 and FIG.6, the operation | movement of the illumination control system 1 which concerns on this embodiment is given as an example, and the case where the two illuminating devices 10 are provided is demonstrated. FIG. 5 is a diagram illustrating an irradiation range of each lighting device 10 when two lighting devices 10 are provided. FIG. 5A shows an irradiation range of each lighting device 10 when all the LEDs 104 included in each lighting device 10 are lit, and FIG. 5B shows a case where the LEDs 104 included in each lighting device 10 are area-driven. The irradiation range of each illuminating device 10 is shown.

  When two lighting devices 10 having a plurality of LEDs 104 are provided, there is a range A (overlapping region) that is irradiated in an overlapping manner, as shown in FIG. That is, the power for irradiating the range A is wasted in each of the two lighting devices 10. In order to reduce this wasteful power consumption, the illumination control system 1 according to the present embodiment executes an illuminance range adjustment process for adjusting the illuminance range of the illumination device 10.

(Illuminance range adjustment processing)
Illuminance range adjustment processing of the illumination control system 1 according to the present embodiment will be described with reference to FIG. FIG. 6 is a flowchart showing a flow of operations related to the illuminance range adjustment process of the illumination control system 1 according to the present embodiment.

  When an adjustment button (not shown) for executing the illuminance range adjustment process of the illumination device 10 provided on the remote controller 11 is pressed, the illuminance range adjustment mode is turned on as shown in FIG. After turning on the illuminance range adjustment mode, the remote controller 11 is installed at a location where illuminance is measured. Here, as shown in FIG. 5A, an example will be described in which the remote controller 11 is installed in a range A irradiated from two illumination devices 10 in an overlapping manner.

  Note that the illuminance range adjustment mode of the remote controller 11 may be turned on and installed, for example, by the user of the remote controller 11. When the illuminance range adjustment mode is turned on, the illuminance range adjustment process for adjusting the illuminance range of the lighting device 10 is started.

  When the illuminance range adjustment mode is turned on, first, the remote controller 11 installed at a location where illuminance is measured starts measurement of illuminance in the illuminance measurement unit 113 (step S101). The illuminance measurement unit 113 notifies the control unit 112 of the illuminance measurement value.

  When the measurement value is notified from the illuminance measurement unit 113 to the control unit 112, the control unit 112 compares the measurement value with a predetermined threshold value (step S102). The predetermined threshold only needs to be stored in the memory 114, for example, and is appropriately read by the control unit 112 when compared with the measured value.

  When the measured value and the threshold value are not the same (NO in step S102), the control unit 112 reads the area drive pattern of the LED 104 stored in the memory 114 in the illumination device 10 according to the difference between the measured value and the threshold value. (Step S104). The area drive pattern will be described later.

  When the area drive pattern is read from the memory 114 by the control unit 112, the remote controller 11 transmits the read area drive pattern to each illumination device 10 via the wireless communication unit 111 (step S104).

  When an area drive pattern is input from the remote controller 11 via the wireless communication unit 101, the main control unit 102 included in each lighting device 10 notifies the LED control unit 103 of the input area drive pattern. The LED control unit 103 area-drives the LED 104 based on the notification from the main control unit 102 (step S105).

  When the area drive of the LED 104 is performed, the remote controller 11 measures the illuminance again (step S101).

  When the measured value and the threshold value are the same (YES in step S102), the control unit 112 included in the remote controller 11 ends the illuminance range adjustment process.

  That is, in the illuminance range adjustment process, the operations from step S101 to S105 are repeated in the lighting device 10 and the remote controller 11 until the measured value and the threshold value are the same.

  When the illuminance range adjustment process is executed as described above, the LEDs 104 included in each lighting device 10 are turned on (driven) and turned off (driven) as shown in FIG. 5B by area driving. Not) LED 104 '. Thereby, as shown in FIG.5 (b), the range irradiated redundantly from each illuminating device 10 can be reduced.

  Therefore, it is possible to adjust the illuminance of the range A irradiated from the two illumination devices 10 to an appropriate illuminance, thereby reducing wasteful power consumption in each of the two illumination devices 10. .

(Area drive pattern)
Here, an example of the area drive pattern will be described.

  As an area drive pattern, for example, as shown in FIG. 5B, a pattern in which all the LEDs 104 arranged in the row closest to the overlapping irradiation range are turned off, and arranged in the nearest row. For example, a pattern in which all the LEDs 104 are turned off can be used.

  In addition, a pattern in which every other LED 104 arranged in a row closest to the overlapping irradiation range is turned off may be adopted. Furthermore, it is also possible to adopt a pattern in which the LEDs 104 arranged in two rows closest to the overlapping irradiation range are turned off in a checkered pattern.

  That is, the area drive pattern may be any pattern that reduces the illuminance in the range A (overlapping area) when the illuminance measured by the illuminance measurement unit 113 is greater than a predetermined threshold.

  For example, the following method can be adopted as a method for determining which column of the illumination device 10 is closest to the overlappingly irradiated range. For example, a mark (not shown) that is recommended to face the other lighting device 10 is marked on one of the side surfaces of the lighting device 10, and the column closest to the surface on which the mark is marked overlaps. Thus, it can be cited as a method of determining the column closest to the irradiated range. In this case, when attaching the illumination device 10, it is more preferable that the user attach each of the two illumination devices 10 so that the marks face each other.

  Of course, the determination method is not limited to this, and for example, a configuration in which a light sensor (not shown) is provided in the illumination device 10 and the direction in which the other illumination device 10 is provided by the light sensor is specified. May be. In this case, among the LEDs 104 provided in the illuminating device 10, the row closest to the surface on which the other illuminating device 10 specified by the optical sensor is arranged is within the overlapping irradiation range. It can be determined as the closest column.

[Illumination simulation]
Next, a simulation of the illuminance around the illumination device 10 when the illuminance range adjustment process in the present embodiment is executed and area driving is performed will be described with reference to FIGS. 7 to 9. FIG. 7 is a diagram illustrating a driving state of each LED 104 of the lighting devices 10a and 10b when two lighting devices 10 (here, the lighting device 10a and the lighting device 10b) are provided in one room. . FIG. 7A shows the driving state of the LED 104 before the simulation is performed, and FIG. 7B shows the driving state of the LED 104 after the simulation is performed.

  FIG. 8 shows simulation conditions and results. FIG. 8 is a diagram illustrating conditions and results for simulating illuminance around the lighting device 10 according to the present embodiment. FIG. 8A shows the simulation conditions, FIG. 8B shows the result of simulation when the illuminance range adjustment process is not executed, and FIG. 8C shows the result of simulation when the illuminance range adjustment process is executed. Is shown.

  Further, FIG. 9 shows the illuminance distribution of the room obtained by the simulation. FIG. 9A shows the illuminance distribution of the room obtained by the simulation when the illuminance range adjustment process is not executed, and FIG. 9B shows the illuminance of the room obtained by the simulation when the illuminance range adjustment process is executed. Distribution is shown.

  As shown in FIG. 7, as a condition for the simulation, the size of the room is 3 m in length and 7 m in width, and 72 LEDs 104 are provided in each of the lighting devices 10a and 10b. Further, as shown in FIG. 8A, the simulation conditions were such that the total luminous flux was 150 lm and the mounting height was 2.5 m.

  In the simulation when the illuminance range adjustment processing is not executed (that is, when the area is not driven), as shown in FIG. 8B, the number of lighting of the LED 104 is 144, the average illuminance of the room is 141 lx, the minimum illuminance is 37 lx, The maximum illuminance was 259 lx.

  Note that the number of lighting of the LEDs 104 is 144, as shown in FIG. 7A, indicates that all the LEDs 104 included in the two lighting devices 10a and 10b are turned on.

  Further, the illuminance distribution of the room obtained by the simulation when the illuminance range adjustment processing is not executed is as shown in FIG. 9A, around the illumination devices 10 a and 10 b and between the illumination devices 10 a and 10 b. Then, it was 200 lx, and the illuminance was higher than necessary.

  On the other hand, in the simulation when the illuminance range adjustment process is executed, as shown in FIG. 8C, the number of LEDs 104 to be lit is 90, the average illuminance of the room is 87.2 lx, the minimum illuminance is 25.7 lx, and the maximum illuminance. Was 162.9 lx.

  In addition, as shown in FIG.7 (b), the lighting number of LED104 is 90 other than 27 LED104 provided in the edge | side facing the illuminating device 10b or 10a in each of illuminating device 10a and 10b. 45 LEDs 104 are turned on.

  In addition, the illuminance distribution of the room obtained by the simulation when the illuminance range adjustment process is executed, as shown in FIG. 9B, is around the lighting devices 10a and 10b and between the lighting devices 10a and 10b. However, it was 100 lx, and there was no range in which the illuminance was higher than necessary.

  In this embodiment, the case where two lighting devices 10 are arranged has been described as an example. However, the present invention is not limited to this, and for example, three or more lighting devices 10 are arranged. It may be.

  For example, when three illumination devices 10 are arranged, the area drive pattern has the smallest number of LEDs 104 that illuminate a range in which the three illumination devices 10 overlap and then the two illumination devices. Any pattern may be used as long as the number of lighting of the LEDs 104 that irradiate the range in which 10 is overlapped is reduced and the number of the LEDs 104 that irradiate the range that is not irradiated repeatedly is the largest.

  According to the above-described configuration, the lighting device 10 individually turns on and off the LEDs 104 according to the area drive pattern derived from the illuminance value around the remote controller 11 and the predetermined threshold value transmitted from the remote controller 11. Control. Thereby, the illuminating device 10 can adjust the illuminance around the remote controller 11 to an appropriate illuminance. Therefore, the illumination control system 1 can reduce the power consumed in the illumination device 10 because the illuminance around the remote controller 11 is not appropriate.

<Embodiment 2>
Next, another embodiment of the illumination control system according to the present invention will be described with reference to FIGS. However, unless otherwise specified, the configuration described in this embodiment is not merely intended to limit the scope of the present invention, but is merely an illustrative example.

[Lighting control system]
The illumination control system according to the present embodiment will be described with reference to FIG. FIG. 10 is a block diagram illustrating an outline of the illumination control system 2 according to the present embodiment. As illustrated in FIG. 10, the illumination control system 2 according to the present embodiment includes an illumination device 20 and a remote controller (remote operation device) 21 that remotely operates the illumination device 20.

(Remote controller)
As shown in FIG. 10, the remote controller 21 includes a wireless communication unit (transmission unit) 211, a control unit (derivation unit) 212, a distance input unit (distance input unit) 213, and a memory 214.

  The distance input unit 213 is a unit that receives a user input (hereinafter simply referred to as a distance value) indicating the distance between the lighting device 20 and the object. Here, examples of the object include an illumination device other than the illumination device 20 and a wall of a room. In the present embodiment, a case where the target object is a lighting device other than the lighting device 20 will be described as an example.

  The control unit 212 controls the operation of each unit included in the remote controller 21. The control unit 212 is means for deriving an area driving pattern referred to in the lighting device 20 from the distance value input from the distance input unit 213.

  Specifically, the control unit 212 reads the area driving pattern of the lighting device 20 from the memory 214 based on the input distance value. The control unit 212 transmits the area driving pattern of the lighting device 20 read from the memory 214 to the lighting device 20 via the wireless communication unit 211.

  The memory 214 stores correspondence information in which each of a plurality of area drive patterns referred to in the lighting device 20 is associated with a distance value.

  The wireless communication unit 211 attaches area drive pattern information indicating the area drive pattern read from the memory 214 by the control unit 212 to the lighting device 20 as a remote control signal. Further, the wireless communication unit 211 may further transmit an on / off signal for controlling lighting and extinguishing of the lighting device 20 as a remote control signal.

(Lighting device)
As illustrated in FIG. 10, the lighting device 20 includes a wireless communication unit 201, a main control unit (control unit) 202, an LED control unit (control unit) 203, and a plurality of LEDs (light emitting elements) 204.

  The wireless communication unit 201 receives a remote control signal transmitted from the remote controller 21. Specifically, an area drive pattern and an on / off signal transmitted as a remote control signal from the remote controller 21 are received. Note that the wireless communication in the wireless communication unit 201 and the wireless communication unit 211 can be realized by, for example, infrared communication, Zigbee, Z-Wave, Bluetooth (registered trademark), or the like.

  The main control unit 202 controls the operation of each unit provided in the lighting device 20. Further, the main control unit 202 notifies the LED control unit 203 of the drive patterns of the plurality of LEDs 204 according to the area drive pattern transmitted from the remote controller 21.

  The LED control unit 203 performs area drive control for individually controlling lighting and extinction of each LED 204 provided in the lighting device 20 according to the area drive pattern notified from the main control unit 202. The main control unit 202 and the LED control unit 203 may further operate to individually control the brightness and the like of each LED 204.

[Area driving in lighting equipment]
Next, the operation of the illumination control system 2 according to the present embodiment will be described using an example in which two illumination devices 20 are provided. When two lighting devices 20 having a plurality of LEDs 204 are provided, there may be a range (overlapping region) where one lighting device 20 and another lighting device 20 irradiate in an overlapping manner.

  That is, power is wasted due to each of the two lighting devices 20 irradiating the same range. In order to reduce this wasteful power consumption, the illumination control system 2 according to the present embodiment executes an illuminance range adjustment process for adjusting the illuminance range of the illumination device 20.

(Illuminance range adjustment processing)
Illuminance range adjustment processing of the illumination control system 2 according to the present embodiment will be described with reference to FIG. FIG. 11 is a flowchart showing a flow of operations related to the illuminance range adjustment process of the illumination control system 2 according to the present embodiment.

  When a distance value between the two illumination devices 20 is input to the remote controller 21 via the distance input unit 213, an illuminance range adjustment process for adjusting the illuminance range of the illumination device 20 is started.

  When the illuminance range adjustment process is started, the remote controller 21 causes the control unit 212 to read an area drive pattern corresponding to the input distance value from the memory 214 (step S201). The area drive pattern in this embodiment will be described later.

  When the area driving pattern is read from the memory 214 by the control unit 212, the remote controller 21 transmits the read area driving pattern to each lighting device 20 via the wireless communication unit 211 (step S202).

  When an area drive pattern is input from the remote controller 21 via the wireless communication unit 201, the main control unit 202 included in each lighting device 20 notifies the LED control unit 203 of the input area drive pattern. The LED control unit 203 drives the area of the LED 204 based on the notification from the main control unit 202 (step S203).

  When the illuminance range adjustment process is executed as described above, the LEDs 204 included in each lighting device 20 are divided into LEDs 204 that are turned on (driven) and LEDs 204 that are turned off (not driven) by area driving. Thereby, it is possible to reduce the range irradiated from each lighting device 20 in an overlapping manner.

  Therefore, it is possible to adjust the illuminance in a range irradiated from the two illumination devices 20 to an appropriate illuminance, thereby reducing wasteful power consumption in each of the two illumination devices 20.

[Area drive pattern]
Next, the area drive pattern of the LED 204 in the lighting device 20 stored in the memory 214 included in the remote controller 21 according to the present embodiment will be described with reference to FIGS. 12 and 13. In the present embodiment, a case where the lighting device 20 includes 72 LEDs 204 will be described as an example. However, the number of LEDs included in the lighting device according to the present invention is, of course, limited to this. It is not a thing.

  FIG. 12 is a diagram illustrating an example of the relationship between the distance between two lighting devices 20 and the number of LEDs 204 provided in each lighting device 20 when the illuminance between the two lighting devices 20 is 50 lx. . FIG. 13 is a graph showing an example of the relationship between the number of LEDs 204 provided in each lighting device 20 and the distance between the two lighting devices 20 with respect to the distance between the two lighting devices 20 when the intermediate illuminance between the two lighting devices 20 is 50 lx. is there.

  As shown in FIG.12 and FIG.13, when the distance between the two illuminating devices 20 is 5 m, in each illuminating device 20, all 72 LEDs 204 should just light up. When the distance between the two lighting devices 20 is 4 m, 69 of the 72 LEDs 204 may be lit in each lighting device 20. Further, when the distance between the two lighting devices 20 is 1 m, 15 of the 72 LEDs 204 may be lit in each lighting device 20.

  Moreover, the area drive pattern should just be set based on the relationship between the distance between the two illuminating devices 20 mentioned above, and the lighting number of LED204 with which each illuminating device 20 is equipped.

  As the area driving pattern, for example, when the distance between the two lighting devices 20 (the distance value input from the distance input unit 203) is 4 m, the area driving pattern is arranged in a row closest to the middle of the two lighting devices 20. In the pattern in which three 204 are turned off among the LEDs 204 that are present, and the input distance value is 1 m, 57 204 in order from the LED 204 arranged in the row closest to the middle of the two lighting devices 20. And a pattern for turning off the light.

  Also, a pattern in which every other LED 204 in a row is turned off, a pattern in which every other row of LEDs 204 is turned off, a pattern in which LEDs 204 in a plurality of rows are turned off in a checkered pattern, or the like can be adopted.

  For example, the following method can be adopted as a method of determining which row of the lighting device 20 is the column closest to the middle of the two lighting devices 20. For example, a mark (not shown) that is recommended to face the other lighting device 20 is marked on one of the side surfaces of the lighting device 20, and the row closest to the surface on which the mark is marked is 2 It can be cited as a method of determining the row closest to the middle of the two lighting devices 20. In this case, when attaching the lighting device 20, it is more preferable that the user attaches each of the two lighting devices 20 so that the marks face each other.

  Of course, the determination method is not limited to this, and for example, a configuration is adopted in which a light sensor (not shown) is provided in the lighting device 20 and the direction in which the other lighting device 20 is provided is specified by the light sensor. May be. In this case, among the LEDs 204 provided in the illuminating device 20, the row closest to the surface on which the other illuminating device 20 specified by the optical sensor is arranged is placed between the two illuminating devices 20. It can be determined as the closest column.

  In the present embodiment, the case where two lighting devices 20 are arranged has been described as an example. However, the present invention is not limited to this, and, for example, three or more lighting devices 20 are arranged. It may be.

  For example, when three illumination devices 20 are arranged, the area drive pattern has the smallest number of LEDs 204 that illuminate the range in which the three illumination devices 20 overlap, and then the two illumination devices. Any pattern may be used as long as the number of LEDs 204 that illuminate a range where 20 is overlapped is reduced, and the number of LEDs 204 that irradiate a range not overlapped is the largest.

<Modification>
In the present embodiment, the case where the object is the lighting device 20, that is, the case where two lighting devices 20 are provided has been described as an example. However, in the present invention, the object is not the lighting device 20. It can also be applied to cases. The object may be, for example, a wall that does not require much illuminance.

  In this modification, an area driving pattern in the case where the irradiation unnecessary body is a wall will be described as an example.

  The area drive pattern may be such that, for example, the number of lightings is reduced from the LEDs 204 arranged closer to the wall of the lighting device 20 as the distance between the lighting device 20 and the wall is shorter. Further, as the distance between the lighting device 20 and the wall increases, the number of lights off may be reduced from the LEDs 204 arranged on the side opposite to the wall of the lighting device 20.

  Of course, in this modification, the area drive pattern described above may be the same as or different from the case where the object is the other lighting device 20.

  Furthermore, the area driving pattern may be different depending on the wall material and color. This is because the number of LEDs 204 that are required to obtain the same illuminance varies depending on the reflectance of light depending on the material and color of the wall. Below, the relationship between the material of a wall and a reflectance is demonstrated.

(Wall material and reflectivity)
Here, the relationship between the wall material and the reflectance will be described with reference to FIG. FIG. 14 is a diagram showing the relationship between the material or color used for the wall (interior material in FIG. 14) and the reflectance.

  As shown in FIG. 14, the material of the wall having a relatively high reflectance is white plaster, white wall, wood (white wood), and the like. Specifically, the reflectance when the wall is white plaster is 60% to 80%, the reflectance when the wall is white wall is 55% to 75%, and the wall is wood (white wood). In this case, the reflectance is 40% to 60%.

  On the other hand, as shown in FIG. 14, the material of the wall having a relatively low reflectance is a dark wall and wood (medium oak). Specifically, the reflectance when the wall is a dark wall is 10% to 30%, and the reflectance when the wall is wood (medium oak) is 10% to 30%.

(Area drive pattern)
As described above, the area driving pattern is preferably different between the case where the illuminance between the lighting device 20 and the other lighting device 20 is set to an appropriate illuminance and the case where the wall illuminance is set to an appropriate illuminance. Further, since the reflectance varies depending on the wall material as described above, it is preferable that the area driving pattern also varies depending on the wall material.

  For example, when the wall is white plaster or the like, the reflectance is high. Therefore, when the distance between the lighting device 20 and the wall is short, the number of LEDs 204 to be lit among the LEDs 204 provided in the lighting device 20 may be reduced. it can.

  On the other hand, when the wall is a dark-colored wall, the reflectance is low. Therefore, even when the distance between the lighting device 20 and the wall is short, the number of LEDs 204 to be lit among the LEDs 204 included in the lighting device 20 is set. If the wall is white stucco, it cannot be reduced as much.

  Therefore, the area drive pattern when the illuminance of the wall is set to an appropriate illuminance is arranged closer to the wall of the illuminating device 20 as the distance between the wall and the illuminating device 20 is shorter and the reflectance of the wall is higher. What is necessary is just to make it reduce the number of lighting from LED204 currently made. Further, as the distance between the wall and the lighting device 20 increases and the reflectance of the wall decreases, the number of extinguishing light is reduced from the LEDs 204 arranged on the side opposite to the wall of the lighting device 20. Good.

  According to the above-described configuration, the lighting device 20 individually controls lighting and extinguishing of each LED 204 according to an area drive pattern derived from the distance between the lighting device 20 and the object transmitted from the remote controller 21. Thereby, the illuminating device 20 can appropriately adjust at least one of the illuminance between the illuminating device 20 and the object and the illuminance of the object. Therefore, the illumination control system 2 can reduce the power consumed in the illumination device 20 because the illuminance is not appropriate.

<Embodiment 3>
Next, another embodiment of the illumination control system according to the present invention will be described with reference to FIG. However, unless otherwise specified, the configuration described in this embodiment is not merely intended to limit the scope of the present invention, but is merely an illustrative example.

[Lighting control system]
The illumination control system according to the present embodiment will be described with reference to FIG. FIG. 15 is a block diagram illustrating an outline of the illumination control system 3 according to the present embodiment. As shown in FIG. 15, the illumination control system 3 according to this embodiment includes an illumination device 30 and a remote controller 31 that remotely operates the illumination device 30.

(Lighting device)
As illustrated in FIG. 15, the illumination device 30 includes a wireless communication unit 301, a main control unit (control unit) 302, an LED control unit (control unit) 303, a plurality of LEDs (light emitting elements) 304, and a distance measurement unit (distance measurement). Means) 305 and a memory 306.

  The wireless communication unit 301 receives a remote control signal transmitted from the remote controller 31. Specifically, an on / off signal or the like for controlling lighting and extinguishing of the lighting device 30 transmitted from the remote controller is received. Note that wireless communication in the wireless communication unit 301 and the wireless communication unit (not shown) included in the remote control 31 can be realized by, for example, infrared communication, Zigbee, Z-Wave, Bluetooth (registered trademark), etc. It is not limited to this.

  The distance measuring unit 305 is a unit that measures the distance from the lighting device 30 to the object. The distance measuring unit 305 notifies the main control unit 302 of the measured distance value (hereinafter also simply referred to as a measured distance value).

  As the distance measuring unit 305, a laser distance sensor that measures a distance using a laser, an ultrasonic distance sensor that measures a distance using ultrasonic waves, and an infrared distance sensor that measures a distance using infrared rays However, the present invention is not limited to this.

  Here, examples of the object include an illumination device other than the illumination device 30 and a wall of a room. In the present embodiment, a case where the target object is a lighting device 30 other than the lighting device 30 will be described as an example.

  The main control unit 302 controls the operation of each unit included in the lighting device 30. Further, the main control unit 302 reads an area drive pattern from the memory 306 from the measured distance value measured by the distance measurement unit 305 and notifies the LED control unit 303 of the area drive pattern.

  The LED control unit 303 performs area drive control for individually controlling lighting and extinction of each LED 304 provided in the illumination device 30 according to the area drive pattern notified from the main control unit 302. The main control unit 302 and the LED control unit 303 may further operate to individually control the brightness and the like of each LED 304.

  The memory 306 stores correspondence information in which each of a plurality of area drive patterns referred to in the main control unit 302 and the LED control unit 303 is associated with a measurement distance value.

[Area driving in lighting equipment]
Next, the operation of the illumination control system 3 according to the present embodiment will be described by taking as an example a case where two illumination devices 30 are provided. When two illumination devices 30 having a plurality of LEDs 304 are provided, there is a range that is irradiated in an overlapping manner. That is, in each of the two lighting devices 30, the power for irradiating the range A is wasted. In order to reduce this wasteful power consumption, the illumination control system 3 according to the present embodiment executes an illuminance range adjustment process for adjusting the illuminance range of the illumination device 30.

(Illuminance range adjustment processing)
Illuminance range adjustment processing of the illumination control system 3 according to the present embodiment will be described with reference to FIG. FIG. 16 is a flowchart showing a flow of operations related to the illuminance range adjustment process of the illumination control system 3 according to the present embodiment.

  First, when the illuminance range adjustment process is started, the lighting device 30 measures the distance from the lighting device 30 to the other lighting device 30 in the distance measuring unit 305 (step S301). The illuminance range adjustment process is started when, for example, a remote control signal indicating that a button (not shown) instructing the start of the illuminance range adjustment process included in the remote controller 31 is pressed is received via the wireless communication unit 301. It only has to be done.

  The distance measuring unit 305 notifies the main control unit 302 of the measured distance value. When the main control unit 302 acquires the measurement distance value from the distance measurement unit 305, the main control unit 302 reads out an area drive pattern corresponding to the measurement distance value from the memory 306 (step S302).

  The main control unit 302 notifies the LED control unit 303 of the read area drive pattern. The LED control unit 303 area-drives the LED 304 based on the notification from the main control unit 302 (step S303).

  When the illuminance range adjustment process is executed as described above, the LEDs 304 included in each lighting device 30 are divided into LEDs 304 that are turned on (driven) and LEDs 304 that are turned off (not driven) by area driving. Thereby, the range irradiated from each illumination device 30 can be reduced.

  Therefore, it is possible to adjust the illuminance in a range irradiated from each lighting device 30 to an appropriate illuminance, and thereby it is possible to reduce useless power consumption in each lighting device 30.

(Area drive pattern)
In addition, since the area drive pattern of LED304 stored in the memory 306 with which the illuminating device 30 which concerns on this embodiment is provided is the same as the area drive pattern in Embodiment 2, description is abbreviate | omitted here.

  In this embodiment, the case where two lighting devices 30 are arranged has been described as an example. However, the present invention is not limited to this, and for example, three or more lighting devices 30 are arranged. It may be.

  For example, when three illumination devices 30 are arranged, the area drive pattern has the smallest number of LEDs 304 that illuminate a range in which the three illumination devices 30 overlap and then the two illumination devices. Any pattern may be used as long as the number of lighting of the LEDs 304 that irradiate the range where 30 is overlapped is reduced and the number of the LEDs 304 that irradiate the range not irradiated repeatedly is the largest.

<Modification>
In the present embodiment, the case where the object is the lighting device 30, that is, the case where the two lighting devices 30 are provided has been described as an example. However, in the present invention, the object is not the lighting device 30. It can also be applied to cases. The object may be, for example, a wall that does not require much illuminance.

  Moreover, when the target object is a wall, the area drive pattern described above may be the same as or different from the case where the target object is the other lighting device 30. Furthermore, the area driving pattern may be different depending on the wall material and color. This is because the number of LEDs 304 that are required to obtain the same illuminance varies depending on the reflectance of light depending on the material and color of the wall.

  In addition, since the area drive pattern in the modification of this embodiment is the same as the area drive pattern in the modification of Embodiment 2, description is abbreviate | omitted here.

  According to the above-described configuration, the lighting device 30 individually controls the lighting and extinguishing of each LED 304 according to the area drive pattern derived from the distance from the lighting device 30 to the object measured by the distance measuring unit 305. Accordingly, the lighting device 30 can appropriately adjust at least one of the illuminance between the lighting device 30 and the object and the illuminance of the object. Therefore, the illumination device 39 can reduce the power consumed in the illumination device 30 because the illuminance is not appropriate.

<Embodiment 4>
Next, another embodiment of the illumination control system according to the present invention will be described with reference to FIG. However, unless otherwise specified, the configuration described in this embodiment is not merely intended to limit the scope of the present invention, but is merely an illustrative example.

[Lighting control system]
The illumination control system according to the present embodiment will be described with reference to FIG. FIG. 17 is a block diagram illustrating an outline of the illumination control system 4 according to the present embodiment. As illustrated in FIG. 17, the illumination control system 4 according to the present embodiment includes an illumination device 40 and a home network (remote operation device) 41 that remotely operates the illumination device 40. The home network 41 is connected to a server (derivation means) 42 via the Internet (network) 43.

(Home network, server)
As shown in FIG. 17, the home network 41 includes a gateway 411, a broadband router 412, and user terminals (acquisition means, derivation means, information terminal) 413.

  The gateway 411 is a network node for connecting networks having different protocols in a computer network.

  The broadband router 412 interconnects two or more different networks in a computer network.

  The user terminal 413 is a unit that receives user input such as arrangement information indicating the arrangement of the lighting device 40 and floor plan information indicating a room layout. The user terminal 413 includes a display unit (not shown), and presents an illuminance measurement position and the like to be described later to the user.

  Examples of the user terminal 413 include a remote controller, a mobile phone, a smartphone, a television receiver, and a personal computer, but the present invention is not limited to this. For example, the user terminal 413 may be a PDA (portable information terminal).

  In the present embodiment, the case where the user terminal 413 is a remote controller and includes an illuminance sensor will be described as an example, but the present invention is not limited to this. For example, when the user terminal 413 is a smartphone and does not include an illuminance sensor, the user terminal 413 is further capable of wireless communication (or wired communication) with the smartphone, and an illuminance sensor unit ( (Not shown).

  The broadband router 412 included in the home network 41 is connected to the server 42 via the Internet 43. The server 42 includes a database 421, and a plurality of area drive patterns are stored in the database 421.

(Lighting device)
As illustrated in FIG. 17, the illumination device 40 includes a wireless communication unit 401, a main control unit (control unit) 402, an LED control unit (control unit) 403, and a plurality of LEDs (light emitting elements) 404.

  The wireless communication unit 401 receives a wireless signal transmitted from the home network 41. Specifically, an area drive pattern transmitted as a radio signal from the home network 41, an on / off signal, and the like are received. Note that wireless communication in the wireless communication unit 401 and the gateway 411 can be realized by, for example, infrared communication, Zigbee, Z-Wave, Bluetooth (registered trademark), or the like.

  The main control unit 402 controls the operation of each unit included in the lighting device 40. Further, the main control unit 402 notifies the LED control unit 403 of area drive patterns of the plurality of LEDs 404 according to the area drive pattern transmitted from the home network 41.

  The LED control unit 403 performs area drive control for individually controlling lighting and extinction of each LED 404 provided in the illumination device 40 in accordance with the area drive pattern notified from the main control unit 402. The main control unit 402 and the LED control unit 403 may further operate to individually control the brightness and the like of each LED 404.

[Area drive]
Next, the operation of the illumination control system 4 according to the present embodiment will be described by taking as an example a case where two illumination devices 40 are provided in one room. When two illuminating devices 40 having a plurality of LEDs 404 are provided in one room, there is a range in which the two illuminating devices 40 are irradiated in an overlapping manner in the room. That is, in each of the two illumination devices 40, power for irradiating the overlapping range is wasted. In order to reduce this wasteful power consumption, the illumination control system 4 according to the present embodiment executes an illuminance range adjustment process for adjusting the illuminance range of the illumination device 40.

(Illuminance range adjustment processing)
Illuminance range adjustment processing of the illumination control system 4 according to the present embodiment will be described with reference to FIG. FIG. 18 is a flowchart showing a flow of operations related to the illuminance range adjustment processing of the illumination control system 4 according to the present embodiment.

  First, the arrangement positions of the two lighting devices 40 arranged in the room are input via the user terminal 413 (step S401). At this time, the room layout may be input together, or the room layout may be set in advance and stored in the database 421 provided in the server 42, and the arrangement position of the lighting device 40 may be input. It is good also as a structure read from the database 421 at the time.

  When the arrangement positions of the two lighting devices 40 are input, the user terminal 413 presents a plot indicating which position in the room the illuminance should be measured to the user by displaying on the display unit (step S402). In accordance with the plot presented on the user terminal 413, the user places the user terminal 413 having the illuminance sensor at a position where the illuminance is to be measured (hereinafter also referred to as an illuminance measurement position).

  Note that the server 42 determines that the plot of the illuminance measurement position presented on the user terminal 413 is, for example, a range in which the two illumination devices 40 are irradiated in an overlapping manner based on the arrangement positions of the two illumination devices 40. Is the position.

  When arranged at the illuminance measurement position, the user terminal 413 measures the illuminance around the user terminal 413, that is, the illuminance around the illuminance measurement position (step S403).

  When the user terminal 413 measures the illuminance around the illuminance measurement position, the user terminal 413 determines whether the illuminance is measured at all the illuminance measurement positions (step S404). Examples of the determination method include a configuration for comparing the number of plots indicating the illuminance measurement position with the number of illuminance measurements, and a configuration for storing which illuminance measurement position is measured. However, the present invention is not limited to this.

  If the user terminal 413 determines that the illuminance at all the illuminance measurement positions has not been measured (NO in step S404), the user terminal 413 again displays the plot indicating the illuminance measurement positions not yet measured on the display unit to the user. Present. The user places the user terminal 413 at the illuminance measurement position according to the plot presented on the user terminal 413, and the user terminal 413 measures the illuminance around the illuminance measurement position. That is, the illumination control system 4 repeats the operations from step S402 to S404 until it is determined YES in step S404.

  When determining that the illuminance at all illuminance measurement positions has been measured (YES in step S404), the user terminal 413 reads the area drive pattern from the database 421 provided in the server 42 according to the measurement result (step S405).

  When the area driving pattern is read out, the user terminal 413 transmits the area driving pattern read out via the gateway 411 to the lighting device 40. When the main control unit 402 included in the illumination device 40 receives the area drive pattern via the wireless communication unit 401, the main control unit 402 notifies the LED control unit 403 of the area drive pattern of the LED 404. The LED control unit 403 drives the plurality of LEDs 404 according to the received area drive pattern (step S406).

  When the illuminance range adjustment process is executed as described above, the LEDs 404 included in each lighting device 40 are divided into LEDs 404 that are turned on (driven) and LEDs 404 that are turned off (not driven) by area driving. Thereby, the range irradiated from each illumination device 40 can be reduced.

  Therefore, it is possible to adjust the illuminance in a range irradiated from the two illumination devices 40 to an appropriate illuminance, thereby reducing wasteful power consumption in each of the two illumination devices 40.

  In the present embodiment, the configuration in which the home network 41 is connected to the server 42 via the Internet 43 and the area driving pattern is stored in the database 421 provided in the server 42 has been described as an example. The invention is not limited to this.

  For example, a configuration in which the home network 41 is not connected to either the Internet 43 or the server 42 and the area driving pattern is stored in the user terminal 413 may be adopted. In this case, the area drive pattern may be stored in a memory (not shown) of the user terminal 413.

[Derivation of area drive pattern]
In the present embodiment, the configuration in which the area driving pattern is read from the database 421 included in the server 42 has been described as an example. However, the lighting control system 4 according to the present invention is not limited to this. For example, a configuration in which an area drive pattern (lighting pattern) is derived in the server 42 based on the room layout and the measured illuminance may be employed.

  Here, the conditions for deriving the area drive pattern will be described below. In the server 42 in the lighting control system 4 according to the present embodiment, in order to derive the area driving pattern, the user may input the following information, for example, via the user terminal 413.

  The user inputs, for example, the model name, mounting height, mounting position, mounting direction, and the like of the lighting device 40 as information (that is, arrangement information) regarding the lighting device 40. In addition, the user inputs the room entrance, depth, ceiling height, ceiling reflectance, wall reflectance, floor reflectance, and the like as room information (that is, floor plan information). Further, the user inputs a desired illuminance and a position of a room where the desired illuminance is desired.

  The server 42 derives an area driving pattern based on the above information input via the user terminal 413 as described below.

(Illuminance just below the lighting device)
First, prior to the derivation of the area drive pattern, a method for deriving the illuminance directly below the illumination device 40 will be described. The illuminance directly below the lighting device 40 can be expressed by the following equation 1 where the distance from the work surface to the lighting device 40 is H (m).

Illuminance = (Illuminance at a position 1 m directly below the illumination device) / H ² (1)
That is, the illuminance is inversely proportional to the square of the distance H from the work surface to the lighting device 40.

  Further, the illuminance at an arbitrary distance directly below the lighting device 40 can be derived from the numerical value of the direct horizontal plane illuminance diagram shown in FIG. FIG. 19 is a diagram illustrating the direct horizontal plane illuminance of the lighting device 40 in the present embodiment.

  In the direct horizontal plane illuminance diagram shown in FIG. 19, the vertical axis represents the vertical distance from the illumination device 40, and the horizontal axis represents the horizontal distance from the illumination device 40. Further, the ½ illuminance angle represents an opening angle at a position where the illuminance immediately below the illuminance is ½ when illuminated perpendicular to the horizontal plane. In the present embodiment, the ½ illuminance angle is 47 °. Further, the 1/2 beam angle represents the angle between the light intensity direction that is 1/2 of the maximum light intensity of the light emitted from the illumination device 40 and the optical axis. In this embodiment, the 1/2 beam angle is 60 °. .

Further, the illuminance of 1 m directly below is calculated not by the initial illuminance (so-called initial illuminance) at which the lighting device 40 is installed, but by illuminance (so-called steady illuminance or average illuminance) that must be maintained at all times. Assuming that the average illuminance is E (lx), the average illuminance E is N (number) of LEDs, F (lm) for luminous flux, M for maintenance rate, U for illumination rate, and A (m ² ) for floor area. Then, it can be expressed by the following formula 2.

E = N ・ F ・ M ・ U / A (2)
The floor area A can be expressed as A = X × Y from the opening of the room as X (m) and the depth of the room as Y (m).

(Lighting rate)
Next, the illumination rate U for deriving the above-described average illuminance E will be described. The illumination rate can be obtained from the reflectance of the ceiling, the wall, and the floor, and the room index described later. However, even if the reflectance and the room index are the same, the illumination rate differs depending on the type of the lighting device 40.

  This is because the light flux emitted from the illumination device 40 varies depending on the shape of the reflector (not shown) included in the illumination device 40 and the cover (not shown). Accordingly, the illumination rate requires data based on actual measurement. In contrast, manufacturers that provide lighting devices provide lighting rate tables that combine room indices and reflectances for each lighting device.

  As described above, illuminance can be obtained by the calculation method described above with reference to the illumination rate table.

(Room index)
Next, a room index for deriving the above-described illumination rate U will be described. The room index is an index for calculating the illuminance in consideration of the shape of the room, and is used for obtaining the illumination rate.

  When the room index is R, the room index R is based on the wall area by using the opening X (m) of the room, the depth Y (m) of the room, and the distance H (m) from the work surface to the lighting device 40. The floor area (that is, the ceiling area) can be expressed by the following formula 3.

Room index R = X · Y / H (X + Y) (3)
(Reflectance)
Next, the reflectance for deriving the above-described illumination rate U will be described. Here, the light finally irradiating the work surface is light obtained by combining light reflected from various surfaces of the room (hereinafter also referred to as combined light).

  As an example of the reflected light to be combined, (1) light that directly reaches the work surface from the lighting device 40, (2) light reflected by the ceiling, (3) light reflected by the wall, and (4) light reflected by the floor And (5) The light of (2) to (4) above is reflected multiple times on at least one of the ceiling, wall and floor.

  Thus, since the light which irradiates a work surface is synthetic | combination light, the illumination rate considers reflectances, such as a wall in which a light reflects, a floor, and a ceiling. Here, the reflectance of the wall, floor, ceiling, etc. will be described with reference to FIG. FIG. 20 is a diagram illustrating a relationship between materials used for walls, floors, ceilings, and the like and the reflectance of the materials in the present embodiment.

  As shown in FIG. 20, materials such as walls, floors, and ceilings having relatively high reflectivity are vinyl cloth, white plaster, white walls, and the like. Specifically, the reflectance of vinyl cloth is about 80% to 90%, the reflectance of white plaster is about 60% to 80%, and the reflectance of white wall is about 55% to 75%.

  On the other hand, as shown in FIG. 14, the walls, floors, and ceilings having a relatively low reflectance are dark walls, wood (medium oak), concrete, and the like. Specifically, the reflectivity of the dark wall is about 10% to 30%, the reflectivity of wood (medium oak) is about 10% to 30%, and the reflectivity of concrete is about 25%. It is.

  For example, when the reflectance of walls, floors, ceilings, and the like is high and the distance between the lighting device 40 and the wall is short, the number of LEDs 404 that are lit among the LEDs 404 provided in the lighting device 40 can be reduced. .

  On the other hand, when the reflectivity of the wall, floor, and ceiling is low, the reflectivity indicates the number of LEDs 404 that are lit among the LEDs 404 provided in the illumination device 40 even when the distance between the illumination device 40 and the wall is short. The higher the price, the less.

(Derivation of area drive pattern)
Next, the derivation of the area drive pattern in the server 42 will be described. The area drive pattern can be derived from the above-described area drive pattern conditions (room layout information and arrangement information).

  First, the user terminal 413 receives an input of a distance (that is, arrangement information) between the two lighting devices 40 from the user. The user terminal 413 transmits the input distance value between the two lighting devices 40 to the server 42 via the Internet 43.

  The server 42 determines candidates for the number of LEDs 404 to be lit among the plurality of LEDs 404 provided in the lighting device 40 according to the arrangement information transmitted from the user terminal 413. Note that the relationship between the distance between the two lighting devices 40 and the number of lighting candidates for the LED 404 is the same as the relationship shown in FIGS.

  Furthermore, the user terminal 413 receives input of floor plan information from the user, and transmits the input floor plan information to the server 42 via the Internet 43. The server 42 determines the number of LEDs 404 to be turned on according to the arrangement information and the floor plan information based on the number of candidates for the number of LEDs 404 to be turned on determined according to the arrangement information.

  For example, when the arrangement information indicates that the distance between the two lighting devices 40 is 5 m, the server 42 first refers to only the arrangement information, and determines the number of lighting candidates of the LEDs 404 in each lighting device 40, for example, As shown in FIG. 12, it is determined that the number is 72. Next, the server 42 further refers to the floor plan information, and determines the number of LEDs 404 to be turned on in each lighting device 40 according to the floor plan of the room indicated by the floor plan information. For example, when the floor plan information indicates that the floor plan of the room is relatively wide, the server 42 determines the number of lighting of the LEDs 404 in each lighting device 40 as 72. When each lighting device 40 includes 73 or more LEDs 404, the server 42 may set the number of LEDs 404 to be turned on to 73 or more.

  In addition, when the floor plan information indicates that the floor plan of the room is relatively narrow, the server 42 determines that the number of LEDs 404 in each lighting device 40 is lighter than 72. This is because when the floor plan is narrow, a desired illuminance can be obtained with light that is weaker (less light emitted from the lighting device 40) than when the floor plan is wide.

  Furthermore, when the floor plan information indicates that the reflectance of the room is relatively high, the server 42 determines the number of LEDs 404 to be turned on to be smaller than the number of LEDs 404 that have been determined as described above. If the floor plan information indicates that the reflectance of the room is relatively low, the server 42 determines the number of LEDs 404 to be turned on to be larger than the number of LEDs 404 that have been determined as described above.

  Further, the server 42 puts one LED 404 in one row in a pattern in which the LEDs 404 that are determined to be turned off are turned off in order from the LED 404 provided in the vicinity of the side facing the other lighting device 40. It is possible to adopt a pattern in which the LEDs 404 in a plurality of rows are turned off in a checkered pattern.

  The server 42 derives the area drive pattern with reference to the floor plan information and the arrangement information as described above. Accordingly, each lighting device 40 can adjust the number of LEDs 404 that irradiate a range to be irradiated overlapping with other lighting devices 40.

  In the present embodiment, the configuration in which the area driving pattern is derived according to the distance between the two lighting devices 40 has been described as an example, but the present invention is not limited to this. For example, three or more lighting devices 40 may be arranged, or only one lighting device 40 may be arranged. Moreover, you may derive | lead-out an area drive pattern according to the distance of the illuminating device 40 and a part of room represented by the wall.

  For example, when three illumination devices 40 are arranged, the area drive pattern has the smallest number of LEDs 404 that illuminate a range in which the three illumination devices 40 overlap, and then the two illumination devices. Any pattern may be used as long as the number of LEDs 404 that illuminate a range irradiated with 40 overlaps decreases and the number of LEDs 404 that irradiate a range not irradiated repeatedly increases.

  When only one lighting device 40 is arranged, the area driving pattern may be derived from the room layout indicated by the floor plan information. For example, when the distance between the lighting device 40 and the wall is short, a pattern that reduces the number of LEDs 404 that illuminate the wall may be used.

  As described above, the illuminating device 40 controls the lighting and extinguishing of each LED 404 according to the lighting pattern derived with reference to the floor plan information and the arrangement information, and thereby the illuminance within the range irradiated by the lighting device 40. Adjust to the appropriate illuminance.

  For example, when two lighting devices 40 are provided in one room, the two lighting devices 40 overlap with each other by referring to the arrangement information indicating the arrangement positions of the two lighting devices 40 and the floor plan information. The illuminance of the irradiated area (overlapping area) can be adjusted to an appropriate illuminance. Moreover, when the illuminating device 40 is arrange | positioned beside a wall, the illumination intensity of a wall can be adjusted to appropriate illumination intensity with reference to floor plan information and arrangement | positioning information.

  Therefore, the illumination control system 4 can reduce the power consumed in the illumination device 40 because the illuminance is not appropriate.

  In the present embodiment, the home network 41 is connected to the server 42 via the Internet 43 and the area drive pattern is derived in the server 42 as an example. However, the present invention is not limited to this. Is not to be done.

  For example, the home network 41 may be connected to neither the Internet 43 nor the server 42, and a configuration in which an area driving pattern is derived in the user terminal 413 may be adopted. In this case, the user terminal 413 functions as an information terminal in which an acquisition unit that acquires floor plan information and position information and a deriving unit that derives an area driving pattern are arranged.

  According to this configuration, since it is not necessary to connect the user terminal 413 to the server 42 every time the area driving pattern is derived, the area driving can be performed even when the environment for connecting the user terminal 413 to the server 42 is not prepared. A pattern can be derived.

  According to the above-described configuration, the lighting device 40 individually turns on and off the LEDs 404 according to the area drive pattern derived with reference to the floor plan information and the arrangement information (or stored in the database 421). By controlling, it is possible to adjust the illuminance in the range irradiated by the illumination device 40 to an appropriate illuminance.

  For example, when two lighting devices 40 are provided in one room, the two lighting devices 40 overlap each other by referring to the arrangement information indicating the arrangement of the two lighting devices 40 and the floor plan information. The illuminance of the irradiated area can be adjusted to an appropriate illuminance. Moreover, when the illuminating device 40 is arrange | positioned beside a wall, the illumination intensity of a wall can be adjusted to appropriate illumination intensity with reference to floor plan information and arrangement | positioning information.

  Therefore, the illumination control system 4 can reduce the power consumed in the illumination device 40 because the illuminance is not appropriate.

  As described above, the lighting control system according to the present invention includes a lighting device having a plurality of light emitting elements, floor plan information indicating a floor plan of a room, and arrangement information indicating a layout of one or a plurality of lighting devices in the room. Obtaining means for obtaining, and deriving means for deriving a lighting pattern of each lighting device with reference to the floor plan information and the arrangement information obtained by the obtaining means, the lighting device comprising the deriving means According to the lighting pattern derived by the above, the lighting and extinguishing of each light emitting element is individually controlled.

  According to said structure, the said illuminating device is controlled according to the lighting pattern derived | led-out with reference to the said floor plan information and the said arrangement | positioning information, and the said illuminating device is controlled by lighting and extinction of each light emitting element separately. Adjust the illuminance in the irradiation range to an appropriate illuminance.

  For example, when two illumination devices are provided in one room, the two illumination devices are overlapped by referring to the arrangement information indicating the arrangement positions of the two illumination devices and the floor plan information. Thus, the illuminance of the irradiated area (overlapping area) can be adjusted to an appropriate illuminance. Moreover, when the said illuminating device is arrange | positioned by the side of a wall, the illumination intensity of a wall can be adjusted to appropriate illumination intensity with reference to the said floor plan information and the said arrangement | positioning information.
