The following embodiment is an example embodying the present invention, and is not an example of limiting the technical scope of the present invention.
　＜１．第１の実施形態＞
　＜１－１．照明制御システムの構成＞
　はじめに、本実施形態に係る照明制御システム１０について説明する。図１には、照明制御システム１０を用いて構成した照明システムＬＳが示されている。また、図２には、照明制御システム１０の各部分を機能的に表すブロック図が示されている。 <1. First Embodiment>
<1-1. Configuration of lighting control system>
First, the illumination control system 10 according to the present embodiment will be described. FIG. 1 shows an illumination system LS configured using an illumination control system 10. FIG. 2 is a block diagram functionally showing each part of the lighting control system 10.
　この照明システムＬＳは、調光調色可能な光源１００の照明制御を行う照明制御システム１０を備えている。この構成例では、光源１００と、照明制御システム１０の要素である照明調整部１１０とが構造的に一体化されて照明部１１とされているが、機能的には、光源１００は照明制御システム１０の制御対象物であり、照明制御システム１０そのものの要素ではない。したがって、光源１００と、照明制御システム１０とを備える構成を照明装置と称する。 The illumination system LS includes an illumination control system 10 that performs illumination control of the light source 100 capable of dimming and toning. In this configuration example, the light source 100 and the illumination adjustment unit 110, which is an element of the illumination control system 10, are structurally integrated into the illumination unit 11, but functionally, the light source 100 is the illumination control system. 10 control objects, not the elements of the lighting control system 10 itself. Therefore, a configuration including the light source 100 and the illumination control system 10 is referred to as an illumination device.
　照明制御システム１０は、光源１００によって得られる光環境を測定する光センサ１２の測定値をもとに光源１００の出力の調整を行う照明調整部１１０と、照明部１１における光源１００の出力調整に使用される条件の入力が行われる操作表示部１３と、を主に備える。 The illumination control system 10 adjusts the output of the light source 100 in the illumination unit 11 and the illumination adjustment unit 110 that adjusts the output of the light source 100 based on the measurement value of the optical sensor 12 that measures the light environment obtained by the light source 100. And an operation display unit 13 for inputting conditions to be used.
　具体的に、図１（ａ）には、部屋などの所定の空間１５０に照明システムＬＳが採用された場合が示されている。光センサ１２及び操作表示部１３が部屋の壁面に固定設置されており、照明部１１が部屋の天井に設けられている。また、図１（ｂ）には、照明システムＬＳが、電気スタンドのようなタスクランプ２５０に採用された場合が示されている。図１（ｂ）では、台部２２０から延び出た脚部２１０の先端に照明部１１が設けられており、光センサ１２及び操作表示部１３が台部２２０の一部分に固定設置されている。 Specifically, FIG. 1A shows a case where the illumination system LS is employed in a predetermined space 150 such as a room. The optical sensor 12 and the operation display unit 13 are fixedly installed on the wall surface of the room, and the illumination unit 11 is provided on the ceiling of the room. FIG. 1B shows a case where the illumination system LS is employed in a task lamp 250 such as a desk lamp. In FIG. 1B, the illumination unit 11 is provided at the tip of the leg part 210 extending from the base part 220, and the optical sensor 12 and the operation display part 13 are fixedly installed on a part of the base part 220.
　この照明部１１が備える光源１００の点灯状態は、光センサ１２における検出信号に基づいて制御される。これによって、所望の光環境が、光環境の調整が所望される位置（以下において、調整位置３と称する。）において得られる。ここでは、調整位置３は、光センサ１２が配置された位置（以下において、光センサ配置位置２と称する場合がある。）とは異なる位置である。 The lighting state of the light source 100 included in the illumination unit 11 is controlled based on a detection signal from the optical sensor 12. Thus, a desired light environment is obtained at a position where adjustment of the light environment is desired (hereinafter referred to as an adjustment position 3). Here, the adjustment position 3 is a position different from the position where the optical sensor 12 is arranged (hereinafter, sometimes referred to as the optical sensor arrangement position 2).
　具体的に、光源１００及び照明制御システム１０を構成する各要素について説明する。 Specifically, each element constituting the light source 100 and the illumination control system 10 will be described.
　照明部１１は、光源１００と光源１００の出力調整を行う照明調整部１１０とを一つの照明器具として構成した部分である。 The illumination unit 11 is a part in which the light source 100 and the illumination adjustment unit 110 that adjusts the output of the light source 100 are configured as one illumination fixture.
　光源１００は、例えば、白熱電球、蛍光灯又はＬＥＤ（Light Emitting Diode）など、種々の形態を採用可能であり、所定の色温度及び光色を有する。光源１００が白熱電球、又は蛍光灯の場合には、光源１００に印加される電圧、又は電流の大きさによって、光源１００の発光状態が可変である。また、光源１００が、例えばＬＥＤの集合の場合には、それら複数のＬＥＤの点灯する数が調節されることによって、その発光状態は可変である。 The light source 100 can adopt various forms such as an incandescent bulb, a fluorescent lamp, or an LED (Light Emitting Diode), and has a predetermined color temperature and light color. When the light source 100 is an incandescent bulb or a fluorescent lamp, the light emission state of the light source 100 is variable depending on the magnitude of voltage or current applied to the light source 100. Further, when the light source 100 is a set of LEDs, for example, the light emission state is variable by adjusting the number of the plurality of LEDs to be lit.
　このような光源１００が発光することによって、光源１００からの位置毎の光環境を表す所定の配光分布３００が得られる。光環境を規定する指標には、例えば光の照度及び相関色温度などが挙げられる。 When the light source 100 emits light, a predetermined light distribution 300 representing a light environment for each position from the light source 100 is obtained. Examples of the index that defines the light environment include light illuminance and correlated color temperature.
　図３には、光源１００による配光分布３００の一例が概略的に平面図で示されている。具体的に、図３（ａ）には、照明システムＬＳが部屋に設置された場合の配光分布３００の平面図が示されている。また、図３（ｂ）には、照明システムＬＳがタスクランプ２５０に採用された場合の配光分布３００の平面図が示されている。なお、図３に示される点線範囲が光源１００の配置位置を表している。また、一重丸が光センサ配置位置２を表しており、二重丸が調整位置３を表している。このような配光分布３００が光源１００の性能に応じて規定される。 FIG. 3 schematically shows an example of a light distribution 300 by the light source 100 in a plan view. Specifically, FIG. 3A shows a plan view of the light distribution 300 when the illumination system LS is installed in a room. FIG. 3B shows a plan view of the light distribution 300 when the illumination system LS is employed in the task lamp 250. The dotted line range shown in FIG. 3 represents the arrangement position of the light source 100. A single circle represents the optical sensor placement position 2 and a double circle represents the adjustment position 3. Such a light distribution 300 is defined according to the performance of the light source 100.
　配光分布３００が本実施形態における照明条件に相当する。このような照明条件は、一般には、光源からの照明によって生じる光環境の場所依存性、すなわち場所によってどのような光環境となるかを示す情報として規定される。 The light distribution 300 corresponds to the illumination condition in this embodiment. Such an illumination condition is generally defined as information indicating the location dependence of the light environment caused by illumination from the light source, that is, the light environment depending on the location.
　配光分布３００における光環境値、即ち色温度及び光色の値は、光源１００の近傍付近における所定の３次元的な範囲で最大値を示し、当該範囲から外方に向かうにつれて減衰する。つまり、光環境値は、光源１００からの相対的な位置（空間的な場所）に応じて異なる。従って、調整位置３と光センサ配置位置２とで得られる色温度及び光色の値は異なる。ただし、配光分布３００の分布状態は規則性を有するため、一方の位置における光環境値が判明すれば、他方の位置における光環境値は、配光分布３００が有する規則性、即ち複数の位置での光環境の相関関係に則って、算出可能である。 The light environment value in the light distribution 300, that is, the color temperature and the light color value, shows a maximum value in a predetermined three-dimensional range in the vicinity of the light source 100 and attenuates from the range toward the outside. That is, the light environment value varies depending on the relative position (spatial place) from the light source 100. Therefore, the color temperature and the light color value obtained at the adjustment position 3 and the optical sensor placement position 2 are different. However, since the distribution state of the light distribution 300 has regularity, if the light environment value at one position is found, the light environment value at the other position is the regularity of the light distribution 300, that is, a plurality of positions. It can be calculated in accordance with the correlation of the light environment.
　より具体的に、配光分布３００における光環境値それぞれが、光源１００の強度変化に応じて、線形な相関関係を有する場合には、照明システムＬＳの製造元での試験によって予め相関係数ｄが算出される。そして、光センサ１２の測定値と相関係数ｄとに基づいて、調整位置３における光環境値が算出される。 More specifically, when each of the light environment values in the light distribution 300 has a linear correlation according to the intensity change of the light source 100, the correlation coefficient d is previously determined by a test at the manufacturer of the illumination system LS. Calculated. Then, based on the measured value of the optical sensor 12 and the correlation coefficient d, the light environment value at the adjustment position 3 is calculated.
　また、配光分布３００における光環境値それぞれが、光源１００の強度変化に応じて、非線形な相関関係を有する場合には、製造元での試験において照明強度を変化させつつ、調整位置３と光センサ配置位置２とにおける光環境値の測定が繰り返される。そして、これら調整位置３と光センサ配置位置２とで測定された光環境値の関係が数値の組あるいは関数として特定される。このような数値の組あるいは関数を用いて作成された、例えば図５に示される数値テーブル４００が予め記憶され、それに基づいて複数の位置のそれぞれにおける光環境の相関関係が、例えば相関係数ｄとして特定される。図５に示される数値テーブル４００では、例えば、配光分布３００のうち、光センサ配置位置２をｘi、調整位置３をｙjとして、これらの位置の相互間における相関係数ｄ（ｄij）が示されている。この相関係数ｄ（ｄij）と光センサ１２の測定値とに基づいて、調整位置３における光環境が推定される。 Further, when each of the light environment values in the light distribution 300 has a non-linear correlation according to the intensity change of the light source 100, the adjustment position 3 and the optical sensor are changed while changing the illumination intensity in the test at the manufacturer. The measurement of the light environment value at the arrangement position 2 is repeated. Then, the relationship between the light environment values measured at the adjustment position 3 and the optical sensor placement position 2 is specified as a set of numerical values or a function. A numerical value table 400 shown in FIG. 5, for example, created using such a numerical value set or function is stored in advance, and the correlation of the light environment at each of a plurality of positions based on the numerical value table 400 is, for example, the correlation coefficient d. Identified as In the numerical value table 400 shown in FIG. 5, for example, in the light distribution 300, the photosensor arrangement position 2 is xi and the adjustment position 3 is yj, and the correlation coefficient d (dij) between these positions is shown. Has been. Based on the correlation coefficient d (dij) and the measured value of the optical sensor 12, the light environment at the adjustment position 3 is estimated.
　このような関係を数式で表現すれば、
　　Ｌ (ｙj) ＝ｄij・Ｌ (ｘi) 　・・・・（式１）
　　Ｌ (ｙj) :　位置ｙjにおける光環境値、
　　Ｌ (ｘi) :　位置ｘiにおける光環境値、
という関係で示される。なお、添字i、jは、空間的な場所を区別する指標である。 If such a relationship is expressed by a mathematical formula,
L (yj) = dij · L (xi) (1)
L (yj): light environment value at position yj
L (xi): Light environment value at position xi,
It is shown in the relationship. The subscripts i and j are indicators for distinguishing spatial locations.
　一般に、光環境値Ｌの場所依存性、すなわち場所によってどのような光環境となるかを示す情報が「照明条件」に相当する。また、具体的に２つの位置ｘi，ｙjが特定されたときに「照明条件」から得られるＬ(ｘi)とＬ(ｙj)との具体的な１つの関係が、その配置状態での「光環境相互の相関関係」に相当する。 Generally, information indicating the place dependency of the light environment value L, that is, what kind of light environment depending on the place corresponds to the “lighting condition”. Further, when two specific positions xi and yj are specified, one specific relationship between L (xi) and L (yj) obtained from the “illumination condition” is “light” in the arrangement state. Corresponds to “correlation between environments”.
　照明条件は、上記のように照明システムＬＳの製造元での試験を通じてあらかじめ決定されておいてもよいが、照明システムＬＳが部屋などに設置される際に照度分布などが測定されることで決定されてもよい。特に、比較的狭い部屋などでは、部屋の壁面からの光反射による影響もあるため、設置先での照度測定に基づいて照明条件が決定されれば、より正確な照明条件が得られる。 The lighting condition may be determined in advance through a test at the manufacturer of the lighting system LS as described above, but is determined by measuring an illuminance distribution or the like when the lighting system LS is installed in a room or the like. May be. In particular, in a relatively small room or the like, there is also an influence due to light reflection from the wall surface of the room. Therefore, if the illumination condition is determined based on illuminance measurement at the installation destination, a more accurate illumination condition can be obtained.
　照明調整部１１０は、マイクロコンピュータ等で構成されており、光センサ１２又は操作表示部１３からの信号に基づいて演算処理を行い、光源１００の出力を調整する。 The illumination adjustment unit 110 is configured by a microcomputer or the like, and performs arithmetic processing based on a signal from the optical sensor 12 or the operation display unit 13 to adjust the output of the light source 100.

As the optical sensor 12, for example, a photomultiplier tube, a photodiode, a photoresistor or the like can be employed. Such an optical sensor 12 is installed in a range where the light from the light source 100 is irradiated and where there is no fear of being blocked.

Installed in position. When the illumination system LS is employed in a task lamp 250 as shown in FIG. 1B, the operation unit 96 and the display unit 95 are installed in a part of the task lamp 250. The operation display unit 13 does not necessarily have to be fixedly installed. This will be described in detail later.
　図６には、照明調整部１１０及び操作表示部１３のハードウェア構成がブロック図で示されている。 FIG. 6 is a block diagram illustrating the hardware configuration of the illumination adjustment unit 110 and the operation display unit 13.

　照明調整部１１０の機能的構成について説明する。 The functional configuration of the illumination adjustment unit 110 will be described.
　照明条件記憶部１１２は、後述する照明条件取得部１３１で取得された照明条件を記憶する部分である。照明条件は、照明条件記憶部１１２から適宜読み出されて、出力調整部１１６に送信される。光源１００の発光による光環境値の場所依存性が光源１００の出力変化によって非線形に変化する場合には、光源１００の複数の出力値に対応した複数パターンの照明条件各々が照明条件記憶部１１２に複数の数値テーブルとして記憶されている。すなわち、図３に示される配光分布３００の場合だけではなく、例えば、図４（ａ），（ｂ）に示される配光分布３００ｂ，３００ｃのような配光分布に基づいて、複数の数値テーブルが記憶されている。そして、複数の数値テーブルの中から、そのときの光源１００の出力（光強度）に応じた数値テーブルが選択及び参照される。 The illumination condition storage unit 112 is a part that stores the illumination conditions acquired by the illumination condition acquisition unit 131 described later. The illumination condition is appropriately read from the illumination condition storage unit 112 and transmitted to the output adjustment unit 116. When the location dependence of the light environment value due to the light emission of the light source 100 changes nonlinearly due to the output change of the light source 100, each of a plurality of patterns of illumination conditions corresponding to the plurality of output values of the light source 100 is stored in the illumination condition storage unit 112. It is stored as a plurality of numerical tables. That is, not only in the case of the light distribution 300 shown in FIG. 3, but also based on the light distribution such as the light distributions 300b and 300c shown in FIGS. The table is stored. Then, a numerical table corresponding to the output (light intensity) of the light source 100 at that time is selected and referred to from among a plurality of numerical tables.
　なお、光源１００の異なる出力に応じて数組程度の照明条件が記憶された状態で、実際の出力が特定された場合には、それらを補間あるいは外挿して、当該実際の出力に対応した照明条件が特定される形態であってもよい。 In addition, when an actual output is specified in a state where several sets of illumination conditions are stored according to different outputs of the light source 100, the illumination corresponding to the actual output is interpolated or extrapolated. It may be a form in which the conditions are specified.
　また、位置変数と光源１００の出力に対応する変数とを含む数式（条件式）で照明条件、即ち光環境値の場所依存性が表現された関数が記憶され、そのときの光源１００の出力値に対応したパラメータ値がその条件式に代入されて照明条件、即ち光環境値の場所依存性が特定される形態であってもよい。 In addition, a function expressing the illumination condition, that is, the location dependence of the light environment value, is stored as a mathematical expression (conditional expression) including a position variable and a variable corresponding to the output of the light source 100, and the output value of the light source 100 at that time is stored. The parameter value corresponding to is substituted into the conditional expression, and the illumination condition, that is, the location dependence of the light environment value may be specified.
　図２の説明に戻って、調整位置記憶部１１３は、調整位置３に関する位置情報が記憶される部分である。この位置情報は、位置情報取得部１３２によって取得される。 Returning to the description of FIG. 2, the adjustment position storage unit 113 is a part in which position information regarding the adjustment position 3 is stored. This position information is acquired by the position information acquisition unit 132.
　光センサ位置記憶部１１４は、光センサ配置位置２に関する位置情報が記憶される部分である。光センサ１２の配置位置に関する情報は位置情報取得部１３２によって取得される。 The optical sensor position storage unit 114 is a part in which position information regarding the optical sensor arrangement position 2 is stored. Information regarding the arrangement position of the optical sensor 12 is acquired by the position information acquisition unit 132.
　光環境目標値記憶部１１５は、調整位置３で所望される光環境値が記憶される部分である。この光環境目標値記憶部１１５から目標値となる光環境に関する信号が読み出され、後述する換算を経て、光センサ１２が検出した測定値との比較に使用される。 The light environment target value storage unit 115 is a part in which a light environment value desired at the adjustment position 3 is stored. A signal related to the light environment serving as a target value is read from the light environment target value storage unit 115 and used for comparison with a measured value detected by the light sensor 12 through conversion described later.
　出力調整部１１６は、光源１００の出力が調整される部分である。出力調整部１１６は、光源１００、光センサ１２、照明条件記憶部１１２、調整位置記憶部１１３、光センサ位置記憶部１１４及び光環境目標値記憶部１１５と電気的に接続されている。出力調整部１１６は、各要素から照明条件、調整位置３、光センサ配置位置２及び光環境の目標値に関する信号を受信する。 The output adjustment unit 116 is a part where the output of the light source 100 is adjusted. The output adjustment unit 116 is electrically connected to the light source 100, the optical sensor 12, the illumination condition storage unit 112, the adjustment position storage unit 113, the optical sensor position storage unit 114, and the light environment target value storage unit 115. The output adjustment unit 116 receives signals related to the illumination condition, the adjustment position 3, the optical sensor arrangement position 2, and the target value of the light environment from each element.
　目標値は、調整位置３での光環境値と光センサ配置位置２での光環境値との相関関係に基づいて光センサ配置位置２での値に換算され、光センサ１２が検出した測定値との比較に使用される。 The target value is converted into a value at the photosensor arrangement position 2 based on the correlation between the light environment value at the adjustment position 3 and the light environment value at the photosensor arrangement position 2, and the measured value detected by the photosensor 12 Used for comparison with.
　そしてこのような比較結果に応じて光源１００の出力が調整され、調整位置３において所望の光環境が実現する。 Then, the output of the light source 100 is adjusted according to such a comparison result, and a desired light environment is realized at the adjustment position 3.
　ここで、操作表示部１３の機能的構成について説明する。 Here, the functional configuration of the operation display unit 13 will be described.
　照明条件取得部１３１は、例えば工場出荷段階で他のコンピュータ等からネットワークを介して光源１００の照明条件を取得する部分である。使用される光源１００に応じた照明条件に関する情報がダウンロードされ、照明条件の取得が行われる。取得された照明条件は照明条件記憶部１１２で記憶される。既述したように、照明条件は照明システムＬＳの設置先の部屋などで設置作業者が照度の場所依存性などの実測を行うことによって決定され、それを照明条件取得部１３１に与える形態であってもよい。 The illumination condition acquisition unit 131 is a part that acquires the illumination condition of the light source 100 from another computer or the like via a network at a factory shipment stage, for example. Information related to the illumination condition corresponding to the light source 100 to be used is downloaded, and the illumination condition is acquired. The acquired illumination condition is stored in the illumination condition storage unit 112. As described above, the illumination conditions are determined by the installation operator performing actual measurements such as the location dependence of the illuminance in the room where the illumination system LS is installed, and the illumination conditions are given to the illumination condition acquisition unit 131. May be.
　なお、照明条件取得部１３１は照明部１１に設けられており、操作表示部１３における操作に応答して照明条件の取得が行われる形態であってもよい。さらに、照明条件は、ネットワークに限らず、例えば可搬型記憶媒体を介して取得される形態、又はコンピュータから直接入力される形態であってもよい。 In addition, the illumination condition acquisition part 131 is provided in the illumination part 11, and the form by which an illumination condition is acquired in response to operation in the operation display part 13 may be sufficient. Further, the lighting condition is not limited to the network, and may be in a form acquired through a portable storage medium or directly input from a computer.
　以上のように、照明条件が照明条件取得部１３１で可変に取得できることにより、光源が変更された場合においても、変更後の光源によって得られる照明条件に基づいて、調整位置３における光環境の調整が可能である。 As described above, since the illumination condition can be variably acquired by the illumination condition acquisition unit 131, even when the light source is changed, the adjustment of the light environment at the adjustment position 3 is performed based on the illumination condition obtained by the changed light source. Is possible.
　なお、照明条件取得部１３１は必ずしも設置されていなくても構わない。この場合、予めデフォルト値として照明条件記憶部１１２に記憶されている照明条件が、出力調整部１１６での調整処理に使用される。 In addition, the illumination condition acquisition part 131 does not necessarily need to be installed. In this case, the illumination condition stored in advance in the illumination condition storage unit 112 as a default value is used for the adjustment process in the output adjustment unit 116.
　位置情報取得部１３２は、光センサ配置位置２及び調整位置３に関する位置情報が可変に取得される部分である。具体的に、位置情報取得部１３２は、例えば表示部９５及び操作部９６で構成されている。 The position information acquisition unit 132 is a part from which position information regarding the optical sensor arrangement position 2 and the adjustment position 3 is variably acquired. Specifically, the position information acquisition unit 132 includes a display unit 95 and an operation unit 96, for example.
　ここで、位置情報の取得について説明する。例えば、光源１００が光を照射する範囲が表示部９５に概略的に示される。具体的には、照明制御システム１０が部屋などの所定の空間１５０に設置された場合には、予め設定された平面視における空間１５０の概略図が表示部９５に視覚的に示される。この空間１５０の概略図は複数の部分領域に分割されている。複数の部分領域の中から所定の部分領域、具体的には、光源１００が設置される位置、光センサ配置位置２及び調整位置３に相当する位置が操作部９６を介して選択される。さらに、光源１００の設置位置から光センサ配置位置２までの距離と、光源１００の設置位置から調整位置３までの距離とが設定入力される。なお、これらの距離は目視による計測で構わない。 Here, the acquisition of location information will be described. For example, the display unit 95 schematically shows a range in which the light source 100 emits light. Specifically, when the illumination control system 10 is installed in a predetermined space 150 such as a room, a schematic diagram of the space 150 in a preset plan view is visually shown on the display unit 95. The schematic diagram of the space 150 is divided into a plurality of partial areas. A predetermined partial area, specifically, a position where the light source 100 is installed, a position corresponding to the photosensor arrangement position 2 and the adjustment position 3 is selected from the plurality of partial areas via the operation unit 96. Further, a distance from the installation position of the light source 100 to the optical sensor arrangement position 2 and a distance from the installation position of the light source 100 to the adjustment position 3 are set and input. These distances may be measured visually.
　続いて、選択された部分領域の高さが、例えば、３通りの設定値から操作部９６を介して選択される。ここで、３通りの設定値は、例えば、部屋における床面、座卓の表面及びテーブルの表面をそれぞれ想定した高さの値となっている。 Subsequently, the height of the selected partial area is selected from the three setting values via the operation unit 96, for example. Here, the three set values are, for example, values of height assuming the floor surface in the room, the surface of the table, and the surface of the table.
　このようにして、調整位置３が調整位置記憶部１１３に記憶されるとともに、光センサ配置位置２が光センサ位置記憶部１１４に記憶される。これによって、所定の空間における光源１００と光センサ配置位置２との相対的な位置関係及び光源１００と調整位置３との相対的な位置関係が特定される。 In this way, the adjustment position 3 is stored in the adjustment position storage unit 113, and the photosensor arrangement position 2 is stored in the photosensor position storage unit 114. As a result, the relative positional relationship between the light source 100 and the photosensor arrangement position 2 in the predetermined space and the relative positional relationship between the light source 100 and the adjustment position 3 are specified.
　また、照明システムＬＳがタスクランプ２５０に採用される場合においても同様の処理及び操作が行われる。この場合には、複数の部分領域が、タスクランプ２５０が設置されるデスク表面の手前領域、デスク表面の中央領域及びデスク表面の奥の領域などを想定した領域として、設定されている。また、高さは、例えば、デスクの上面と床面とを想定した２通りの設定値から選択される。 Also, when the lighting system LS is employed in the task lamp 250, the same processing and operation are performed. In this case, a plurality of partial areas are set as areas assuming a front area of the desk surface on which the task lamp 250 is installed, a central area of the desk surface, a back area of the desk surface, and the like. The height is selected from, for example, two setting values assuming the upper surface and the floor surface of the desk.
　以上のように、光センサ配置位置２及び調整位置３それぞれに関する位置情報が位置情報取得部１３２で可変に取得されることにより、光センサ配置位置２、又は調整位置３が変更されても、変更位置が反映された位置情報に基づいて、光源の出力を調整することができる。 As described above, position information regarding each of the optical sensor arrangement position 2 and the adjustment position 3 is variably acquired by the position information acquisition unit 132, so that even if the optical sensor arrangement position 2 or the adjustment position 3 is changed, the change is made. The output of the light source can be adjusted based on the position information reflecting the position.
　なお、位置情報取得部１３２は、必ずしも設けられていなくても構わない。この場合、予めデフォルト値として調整位置記憶部１１３に記憶されている調整位置３に関する位置情報と、予めデフォルト値として光センサ位置記憶部１１４に記憶されている光センサ配置位置２に関する位置情報とが、出力調整部１１６での調整処理に使用される。特に、図１（ｂ）のようなタスクランプ２５０の場合には、光センサ配置位置２は机面の端部に固定され、調整位置３は机面の中央部ないしはそれよりも手前側であることが多いと考えられる。従って、そのようなデフォルト値を用いても実用性が損なわれることはない。 Note that the position information acquisition unit 132 is not necessarily provided. In this case, position information related to the adjustment position 3 stored in advance in the adjustment position storage unit 113 as a default value, and position information related to the photosensor arrangement position 2 stored in the photosensor position storage unit 114 as a default value in advance. , And used for adjustment processing in the output adjustment unit 116. In particular, in the case of the task lamp 250 as shown in FIG. 1B, the optical sensor placement position 2 is fixed to the end of the desk surface, and the adjustment position 3 is the central part of the desk surface or the front side thereof. It is thought that there are many cases. Therefore, even if such default values are used, practicality is not impaired.
　上述のように照明条件取得部１３１と位置情報取得部１３２とが設けられていない場合には、操作表示部１３は設置されていなくてもよい。 If the illumination condition acquisition unit 131 and the position information acquisition unit 132 are not provided as described above, the operation display unit 13 may not be installed.
　＜１－２．処理の流れ＞
　図７には、本実施形態における処理の流れを表すフローチャートが示されている。このフローチャートに基づいて処理の流れを説明する。 <1-2. Flow of processing>
FIG. 7 shows a flowchart showing the flow of processing in the present embodiment. The flow of processing will be described based on this flowchart.
　はじめに、照明条件取得部１３１が光源１００の照明条件を取得する（ステップＳ１）。そして、照明条件記憶部１１２が照明条件取得部１３１で取得された照明条件を記憶する。既述したように、このステップＳ１は、工場出荷前に行ってもよく、照明システムＬＳの設置先で行われてもよい。 First, the illumination condition acquisition unit 131 acquires the illumination condition of the light source 100 (step S1). Then, the illumination condition storage unit 112 stores the illumination condition acquired by the illumination condition acquisition unit 131. As described above, this step S1 may be performed before shipment from the factory, or may be performed at the installation destination of the illumination system LS.
　位置情報取得部１３２によって取得された調整位置３に関する位置情報は調整位置記憶部１１３に記憶される（ステップＳ２）。これは、使用者などの操作入力（選択入力）に基づいて実行される。また、位置情報取得部１３２によって取得された光センサ配置位置２に関する位置情報は光センサ位置記憶部１１４に記憶される（ステップＳ３）。なお、ステップ２とステップ３との順序は逆であっても構わない。また、調整位置３及び光センサ配置位置２がすでに調整位置記憶部１１３及び光センサ位置記憶部１１４に記憶されている場合には、これらの工程は省略される。 The position information related to the adjustment position 3 acquired by the position information acquisition unit 132 is stored in the adjustment position storage unit 113 (step S2). This is executed based on an operation input (selection input) by a user or the like. Further, the position information related to the photosensor arrangement position 2 acquired by the position information acquisition unit 132 is stored in the photosensor position storage unit 114 (step S3). Note that the order of step 2 and step 3 may be reversed. Further, when the adjustment position 3 and the optical sensor arrangement position 2 are already stored in the adjustment position storage unit 113 and the optical sensor position storage unit 114, these steps are omitted.
　光源１００の照明条件に関する情報が照明条件記憶部１１２から出力調整部１１６に送信される。また、光センサ配置位置２及び調整位置３に関する位置情報が、光センサ位置記憶部１１４と調整位置記憶部１１３とからそれぞれ出力調整部１１６に送信される。そして、これらの光センサ配置位置２及び調整位置３における光環境の値、即ち、照度、又は相関色温度の相関関係が照明条件に基づいて算出され、相関係数ｄとして出力調整部１１６に記憶される（ステップＳ４）。 Information related to the illumination condition of the light source 100 is transmitted from the illumination condition storage unit 112 to the output adjustment unit 116. In addition, position information regarding the optical sensor arrangement position 2 and the adjustment position 3 is transmitted from the optical sensor position storage unit 114 and the adjustment position storage unit 113 to the output adjustment unit 116, respectively. Then, the value of the light environment at the photosensor arrangement position 2 and the adjustment position 3, that is, the correlation between the illuminance or the correlated color temperature is calculated based on the illumination condition, and stored in the output adjustment unit 116 as the correlation coefficient d. (Step S4).
　ここで、光源１００の出力に応じた複数の照明条件が照明条件記憶部１１２に記憶されている場合には、その中から選択された１つの照明条件が照明条件記憶部１１２から読出され、出力調整部１１６に与えられる。なお、照明システムＬＳの電源がオンされた直後には、あらかじめデフォルト値として指定されている標準的な照明条件が読み出される。 Here, when a plurality of illumination conditions corresponding to the output of the light source 100 are stored in the illumination condition storage unit 112, one illumination condition selected from them is read from the illumination condition storage unit 112 and output. The adjustment unit 116 is given. Note that immediately after the lighting system LS is turned on, standard illumination conditions designated in advance as default values are read out.
　続いて、目標値となる光環境値、即ち調整位置３にて所望される光環境値が、光環境目標値記憶部１１５から読み出され、出力調整部１１６において設定される（ステップＳ５）。この光環境の目標値はデフォルト値であってもよく、使用者の操作によって可変であってもよい。目標値を可変とする態様は別の実施形態として後述する。 Subsequently, the light environment value serving as the target value, that is, the light environment value desired at the adjustment position 3, is read from the light environment target value storage unit 115 and set in the output adjustment unit 116 (step S5). The target value of the light environment may be a default value or may be variable by a user operation. A mode in which the target value is variable will be described later as another embodiment.
　そして、光センサ配置位置２における光環境値が、光センサ１２によって測定される（ステップＳ６）。光センサ１２の検出信号は、出力調整部１１６に送信される。出力調整部１１６は、光センサ配置位置２での光環境の測定値を、相関係数ｄを用いて、調整位置３における測定値に換算する（ステップＳ７）。つまり、調整位置３における光環境の測定値が換算値として算出される。 Then, the light environment value at the light sensor arrangement position 2 is measured by the light sensor 12 (step S6). A detection signal of the optical sensor 12 is transmitted to the output adjustment unit 116. The output adjustment unit 116 converts the measurement value of the light environment at the optical sensor arrangement position 2 into the measurement value at the adjustment position 3 using the correlation coefficient d (step S7). That is, the measurement value of the light environment at the adjustment position 3 is calculated as a converted value.
　そして、換算値と光環境目標値記憶部１１５に記憶されている目標値との比較が行われ、換算値と目標値との差がゼロであるか否かが判断される（ステップＳ８）。光環境の換算値が目標値と一致した段階、又はその差が所定の許容範囲内に収まった段階で、一連の処理は終了する。つまり、調整位置３において目標の光環境が実現される。 Then, the converted value is compared with the target value stored in the light environment target value storage unit 115, and it is determined whether or not the difference between the converted value and the target value is zero (step S8). The series of processing ends when the converted value of the light environment matches the target value, or when the difference falls within a predetermined allowable range. That is, the target light environment is realized at the adjustment position 3.
　なお、ステップＳ６の光センサ１２での計測は所定の時間間隔で周期的に行われる。そして、ステップＳ７を経て改めてステップＳ８が実行される。 Note that the measurement by the optical sensor 12 in step S6 is periodically performed at predetermined time intervals. And step S8 is performed anew through step S7.
　換算値と目標値との差がゼロではない場合、又は許容範囲外の場合には、この差がゼロになるように、出力調整部１１６は、光源１００に信号を送信し、光源１００の出力の調整を行う（ステップＳ９）。つまり、フィードバック制御が行われる。 When the difference between the converted value and the target value is not zero or outside the allowable range, the output adjustment unit 116 transmits a signal to the light source 100 so that the difference becomes zero, and the output of the light source 100 Is adjusted (step S9). That is, feedback control is performed.
　フィードバック制御が行われて光源１００の出力が変化した際には、照明条件の再設定（ステップＳ１０）が行われる。即ち、フィードバック制御が行われた後では、それ以前における光源１００の光強度が変化している可能性があるため、光源１００の光強度の最新の状況に応じた１つの照明条件が、照明条件記憶部１１２に記憶されている複数の照明条件の中から選択及び読出され、制御に使用される。この目的で、各回のフィードバック制御が収束した際には、そのときの光源１００の光強度の情報が、出力調整部１１６または照明条件記憶部１１２に記憶される。具体的には、各回のフィードバック制御が収束した際に出力調整部１１６から光源１００に与えている信号の値が光源１００の出力値に換算され、記憶される。 When the feedback control is performed and the output of the light source 100 is changed, the illumination condition is reset (step S10). That is, after the feedback control is performed, there is a possibility that the light intensity of the light source 100 before that is changed, so that one illumination condition corresponding to the latest situation of the light intensity of the light source 100 is the illumination condition. It is selected and read out from a plurality of illumination conditions stored in the storage unit 112 and used for control. For this purpose, when each feedback control converges, information on the light intensity of the light source 100 at that time is stored in the output adjustment unit 116 or the illumination condition storage unit 112. Specifically, the value of the signal given from the output adjustment unit 116 to the light source 100 when each feedback control converges is converted into an output value of the light source 100 and stored.
　なお、光環境目標値記憶部１１５で記憶された、調整位置３における目標値が、相関係数ｄに基づいて、光センサ配置位置２における目標値に換算され、この換算値と光センサ１２による測定値との差を調整する制御形態であってもよい。 The target value at the adjustment position 3 stored in the optical environment target value storage unit 115 is converted into the target value at the optical sensor arrangement position 2 based on the correlation coefficient d. It may be a control form that adjusts the difference from the measured value.
　以上のように、本実施形態に係る照明制御システム１０では、光センサ１２が、光環境の調整が所望される位置とは異なる位置に設置された状態で、調整位置３における光環境の調整を行うことが可能である。このため、光センサ１２が設置されていることによって使用者の行動が制限されることなく、所望の光環境が所望の位置において実現可能である。 As described above, in the illumination control system 10 according to the present embodiment, the light sensor 12 is adjusted at the adjustment position 3 in a state where the light sensor 12 is installed at a position different from the position where adjustment of the light environment is desired. Is possible. For this reason, a desired light environment is realizable in a desired position, without a user's action being restrict | limited by installing the optical sensor 12. FIG.
　また、照明制御システム１０が照明条件取得部１３１を備えることによって、例えば、経年劣化、又は光源１００の交換により、光源１００が設置段階とは異なる照明条件を有する場合であっても、その都度適切な照明条件を取得可能である。このため、正確な照明条件に基づいて、光源１００の出力の調整が可能である。 In addition, since the illumination control system 10 includes the illumination condition acquisition unit 131, for example, when the light source 100 has an illumination condition different from the installation stage due to aging or replacement of the light source 100, it is appropriate each time. Various lighting conditions can be obtained. For this reason, the output of the light source 100 can be adjusted based on accurate illumination conditions.
　また、照明制御システム１０が位置情報取得部１３２を備えることによって、光センサ配置位置２、又は調整位置３の位置情報は更新可能である。このため、光センサ配置位置２、又は調整位置３を変更しなければならない状況であっても、変更位置に応じた適切な位置情報に基づいて、光源１００の出力の調整が可能である。 In addition, since the illumination control system 10 includes the position information acquisition unit 132, the position information of the optical sensor arrangement position 2 or the adjustment position 3 can be updated. For this reason, even in a situation where the optical sensor arrangement position 2 or the adjustment position 3 must be changed, the output of the light source 100 can be adjusted based on appropriate position information corresponding to the changed position.
　＜２．第２の実施形態＞
　上記第１の実施形態では、光センサ１２は固定設置されていたが、このような形態に限られない。光センサ１２は、移動自在の可搬性の形態であっても構わない。図８（ａ），（ｂ）では、光センサ１２がリモートコントローラ３０に搭載されている場合の、照明制御システム１０ｂを用いた照明システムＬＳｂが示されている。このリモートコントローラ３０は、照明部１１、特に照明調整部１１０とは分離されて設けられ、照明調整部１１０への指示に用いられる。光センサ１２はリモートコントローラ３０の移動に応じて自在に配置位置を変更することが可能である。なお、本実施形態では、リモートコントローラ３０が可搬型端末機器に相当する。光センサ１２は、リモートコントローラ３０に限られず、例えばスマートフォンなどに搭載されても構わない。 <2. Second Embodiment>
In the said 1st Embodiment, although the optical sensor 12 was fixedly installed, it is not restricted to such a form. The optical sensor 12 may be in a movable and portable form. 8A and 8B show an illumination system LSb using the illumination control system 10b when the optical sensor 12 is mounted on the remote controller 30. FIG. The remote controller 30 is provided separately from the illumination unit 11, particularly the illumination adjustment unit 110, and is used for instructions to the illumination adjustment unit 110. The arrangement position of the optical sensor 12 can be freely changed according to the movement of the remote controller 30. In the present embodiment, the remote controller 30 corresponds to a portable terminal device. The optical sensor 12 is not limited to the remote controller 30 and may be mounted on, for example, a smartphone.
　図９には、本実施形態に係る照明制御システム１０ｂのブロック図が示されている。 FIG. 9 shows a block diagram of the illumination control system 10b according to the present embodiment.
　このようなリモートコントローラ３０には、光センサ１２とともに、位置情報取得部１３２も設けられている。光センサ１２、又は位置情報取得部１３２からの所定の信号は、端末側通信部３１を介して照明部１１の照明部側通信部１１８に送られ、照明部側通信部１１８から照明部１１の各部に送られる。なお、位置情報取得部１３２は、第１の実施形態と同様の形態、即ち操作部９６及び表示部９５で構成されている。また、端末側通信部３１が本発明における送信部に相当する。 Such a remote controller 30 is provided with a position information acquisition unit 132 together with the optical sensor 12. A predetermined signal from the optical sensor 12 or the position information acquisition unit 132 is sent to the illumination unit side communication unit 118 of the illumination unit 11 via the terminal side communication unit 31, and from the illumination unit side communication unit 118 to the illumination unit 11. Sent to each part. The position information acquisition unit 132 is configured in the same manner as in the first embodiment, that is, the operation unit 96 and the display unit 95. The terminal side communication unit 31 corresponds to the transmission unit in the present invention.
　このように、リモートコントローラ３０は位置情報取得部１３２を備えるため、使用者は任意の位置で、光センサ配置位置２及び調整位置３に関する位置情報を設定可能であり、操作入力を行いやすくなる。 As described above, since the remote controller 30 includes the position information acquisition unit 132, the user can set position information regarding the optical sensor arrangement position 2 and the adjustment position 3 at an arbitrary position, which facilitates operation input.
　また、光センサ１２がリモートコントローラ３０に設置されていることによって、リモートコントローラ３０を移動させながら、任意の位置における光環境を測定することが可能である。 Further, since the optical sensor 12 is installed in the remote controller 30, it is possible to measure the light environment at an arbitrary position while moving the remote controller 30.
　また、使用者がリモートコントローラ３０を保持しながら移動して、光センサ１２による光環境の測定と、位置情報取得部１３２による位置情報の取得とが行われることにより、照明条件の測定が可能である。このため、照明条件記憶部１１２で記憶される照明条件を、実際に設置環境に置かれた状態の光源１００に基づいて測定を行ったうえで設定することが可能である。 In addition, the user moves while holding the remote controller 30 to measure the light environment by the optical sensor 12 and to acquire the position information by the position information acquisition unit 132, so that the illumination condition can be measured. is there. For this reason, it is possible to set the illumination conditions stored in the illumination condition storage unit 112 after performing measurement based on the light source 100 that is actually placed in the installation environment.
　位置情報取得部１３２は、自動的に位置情報を計測可能な位置計測部を備える構成であってもよい。例えば、無線測距計、赤外線測距計、超音波測距計、又は室内ＧＰＳなどが位置情報取得部１３２に採用されることで、使用者の操作による操作表示部１３への入力が行われることなく、位置情報は自動的に更新される。なお、この場合、光源１００の位置は事前に設定入力されている。調整位置３は、事前に使用者がリモートコントローラ３０を実際に光環境の調整が所望される位置に配置して操作を行うことにより、位置情報取得部１３２が当該位置における位置情報を得ることによって設定される。この調整位置３は、使用者が同様の操作を行うことで更新できる。また、光センサ配置位置２は、位置情報取得部１３２によって常時更新可能である。 The position information acquisition unit 132 may include a position measurement unit that can automatically measure position information. For example, a radio range finder, an infrared range finder, an ultrasonic range finder, an indoor GPS, or the like is employed in the position information acquisition unit 132, whereby an input to the operation display unit 13 by a user operation is performed. Instead, the position information is automatically updated. In this case, the position of the light source 100 is set and input in advance. The adjustment position 3 is obtained when the user arranges the remote controller 30 at a position where the adjustment of the light environment is actually desired and operates in advance, and the position information acquisition unit 132 obtains the position information at the position. Is set. The adjustment position 3 can be updated by the user performing a similar operation. In addition, the optical sensor arrangement position 2 can be constantly updated by the position information acquisition unit 132.
　例えば、使用者がリモートコントローラ３０を保持しながら移動し、光センサ１２による光環境の測定と、位置情報取得部１３２による位置情報の取得とが行われる場合には、位置毎の光環境の測定値が求められる。従って、測定値の強度の空間分布に基づいて光源１００の位置は自動的に認識（演算で推定）されるため、光源１００の設置位置の手動入力が行われることなく、光源１００と光センサ配置位置２との相対的な位置関係は自動的に設定可能である。 For example, when the user moves while holding the remote controller 30 and the measurement of the light environment by the optical sensor 12 and the acquisition of the position information by the position information acquisition unit 132 are performed, the measurement of the light environment for each position is performed. A value is determined. Accordingly, since the position of the light source 100 is automatically recognized (estimated by calculation) based on the spatial distribution of the intensity of the measurement value, the light source 100 and the optical sensor arrangement are not manually input without setting the installation position of the light source 100. The relative positional relationship with position 2 can be set automatically.
　このように、光センサ配置位置２は、自在に変更可能であり、光センサ配置位置２が変更される都度、相関係数ｄの再設定が行われる。 Thus, the photosensor arrangement position 2 can be freely changed, and the correlation coefficient d is reset every time the photosensor arrangement position 2 is changed.
　以上のように、第２の実施形態に係る照明制御システム１０ｂでは、光センサ１２及び位置情報取得部１３２がリモートコントローラ３０のような可搬型端末機器に搭載されている。このため、可変型端末機器を移動させることで光センサ配置位置２を自在に変更できるとともに、使用者は、操作しやすい位置で、照明調整部１１０における位置情報の設定変更を容易に行うことができる。 As described above, in the illumination control system 10 b according to the second embodiment, the optical sensor 12 and the position information acquisition unit 132 are mounted on a portable terminal device such as the remote controller 30. For this reason, the optical sensor arrangement position 2 can be freely changed by moving the variable terminal device, and the user can easily change the setting of the position information in the illumination adjustment unit 110 at an easy-to-operate position. it can.
　また、実際の使用環境に置かれた状態の光源１００によって得られる照明条件がリモートコントローラ３０を移動させることで測定可能である。従って、照明条件は、光源１００の設置後であっても更新可能であり、光源１００の経年劣化が生じても、正確な照明条件を得られる。 Moreover, the illumination conditions obtained by the light source 100 in the actual usage environment can be measured by moving the remote controller 30. Therefore, the illumination condition can be updated even after the light source 100 is installed, and an accurate illumination condition can be obtained even if the light source 100 deteriorates over time.
　また、位置情報取得部１３２は自動計測によって位置情報を取得することも可能であるため、使用者は入力操作をしなくても容易に位置情報を取得でき、使用者の利便性は向上する。 Further, since the position information acquisition unit 132 can also acquire position information by automatic measurement, the user can easily acquire the position information without performing an input operation, and the convenience for the user is improved.
　なお、図９に示される照明部１１が、光源１００、出力調整部１１６および照明側通信部１１８で構成されており、その他の構成要素、即ち照明条件記憶部１１２、調整位置記憶部１１３、光センサ位置記憶部１１４、及び光環境目標値記憶部１１５などがリモートコントローラ３０に備わる形態であってもよい。この場合、その他の構成要素が備わるリモートコントローラ３０、即ち本実施形態における可搬型端末機器が、出力の変更及び通信可能な既設の照明光源に対して、用いられることによって照明制御システム１０ｂは実現可能である。 The illumination unit 11 shown in FIG. 9 includes a light source 100, an output adjustment unit 116, and an illumination-side communication unit 118. Other components, that is, an illumination condition storage unit 112, an adjustment position storage unit 113, light The remote controller 30 may include the sensor position storage unit 114, the light environment target value storage unit 115, and the like. In this case, the illumination control system 10b can be realized by using the remote controller 30 including other components, that is, the portable terminal device according to the present embodiment, for an existing illumination light source capable of changing output and communicating. It is.
　＜３．第３の実施形態＞
　上記実施形態では、光環境目標値記憶部１１５に記憶されている光環境の目標値は、一旦設定されると更新されることはなかったが、このような形態には限られない。光環境の目標値は更新可能な形態であっても構わない。 <3. Third Embodiment>
In the above embodiment, the light environment target value stored in the light environment target value storage unit 115 has not been updated once set, but is not limited to such a form. The target value of the light environment may be in an updatable form.
　図１０には、本実施形態に係る照明制御システム１０ｃを用いた照明システムＬＳｃのブロック図が示されている。図１０に示されるように、光環境目標値取得部１３３が操作表示部１３に設けられており、この光環境目標値取得部１３３を介して光環境の目標値を取得可能である。具体的には光環境の目標値は、例えば使用者が、操作部９６及び表示部９５を介して入力することにより、更新可能である。 FIG. 10 shows a block diagram of a lighting system LSc using the lighting control system 10c according to the present embodiment. As shown in FIG. 10, the light environment target value acquisition unit 133 is provided in the operation display unit 13, and the light environment target value can be acquired via the light environment target value acquisition unit 133. Specifically, the target value of the light environment can be updated, for example, when the user inputs it via the operation unit 96 and the display unit 95.
　使用者は、光環境の目標値を任意の値に変更可能であるため、例えば、季節、時間、天候及び気温などの状況に応じて、光環境の目標値を適切な値に設定することができる。 Since the user can change the target value of the light environment to an arbitrary value, for example, the target value of the light environment can be set to an appropriate value according to the situation such as season, time, weather, and temperature. it can.
　例えば、目標値が、複数の選択値からの択一的選択あるいは操作入力された値とする場合、読書などの際には比較的高い目標値が設定され、テレビ鑑賞の際には比較的低い目標値が設定されるなど、目標値を可変とすることによって多様な照明調整が可能である。 For example, when the target value is an alternative selection or operation input value from a plurality of selection values, a relatively high target value is set for reading and the like, and a relatively low value for watching TV Various illumination adjustments are possible by making the target value variable, such as setting the target value.
　この第３の実施形態においても、第２の実施形態のように光センサ１２は移動可能な形態とすることができる。 Also in the third embodiment, the optical sensor 12 can be moved as in the second embodiment.
　日光などの外光が部屋の一部にだけ差し込んでおり、一方で部屋の奥は比較的暗い場合には、外光が当たる位置に光センサ１２が配置されると、光センサは高い測定値を検出する。このため、制御ループは光源１００の出力を低下させるように作用してしまう。 When external light such as sunlight is only inserted into a part of the room and the interior of the room is relatively dark, if the optical sensor 12 is arranged at a position where the external light hits, the optical sensor has a high measured value. Is detected. For this reason, the control loop acts to reduce the output of the light source 100.
　このような状況に対処するために、光センサが固定設置される場合には、外光の影響が少ない位置に光センサ１２を設置することが好ましい。第３の実施形態のように目標値を可変とする場合には、仮に外光の影響が出ても、目標値を高く変更することによって対処可能である。また、第２の実施形態のように光センサを可搬とする場合には、そのときどきで、光センサが、外光が当たらない箇所に移動されることによって、そのような外光の影響を抑制することが可能となる。 In order to cope with such a situation, when the optical sensor is fixedly installed, it is preferable to install the optical sensor 12 at a position where the influence of external light is small. When the target value is made variable as in the third embodiment, even if the influence of external light appears, it can be dealt with by changing the target value higher. In addition, when the optical sensor is portable as in the second embodiment, sometimes the optical sensor is moved to a place where the external light does not hit, thereby affecting the influence of such external light. It becomes possible to suppress.
　以上、３つの実施形態では、光源が1箇所に設置されている例で説明したが、本発明に係る照明制御システムは、光源が複数箇所に設置されている場合においても適用が可能である。 As described above, in the three embodiments, the example in which the light source is installed at one place has been described. However, the illumination control system according to the present invention can be applied even when the light source is installed at a plurality of places.
