Description
本発明は、照明光の照射面の照度が略一定となるように複数の照明装置の光出力を制御する照明制御装置に関する。 The present invention relates to an illumination control device that controls the light output of a plurality of illumination devices such that the illuminance of an illumination light irradiation surface is substantially constant.
従来、照明光の照射面の照度が略一定となるように複数の照明装置の光出力を制御する照明制御装置において、天井面に取り付けられた照度センサにて、照明装置から照射された光や外光(例えば、窓から入射された太陽光)の床面、壁面、及び机上からの反射光を検出し、その検出した反射光に応じて照明装置を調光制御して床面や机上の照度を一定に保つようにされている。 Conventionally, in an illumination control device that controls the light output of a plurality of illumination devices so that the illumination intensity of the illumination light irradiation surface is substantially constant, the illumination sensor attached to the ceiling surface can irradiate light emitted from the illumination device. Detects reflected light from the floor surface, wall surface, and desk surface of outside light (for example, sunlight incident from a window), and dimming the lighting device according to the detected reflected light to control light on the floor surface or desk surface The illuminance is kept constant.
この照明制御装置において、天井面に設けられた照度センサに、例えば、隣接建物の窓ガラスから反射した太陽光が直接入射したり、照度センサ直下に光反射率の高い白い紙などが置かれた場合には、照度センサが検出する照度が高くなるために、照明装置の光出力を低下させる方向に調光されてしまうことがある。このため、実際の机上や床面は設定照度以下となってしまう課題がある。 In this lighting control device, for example, sunlight reflected from the window glass of an adjacent building is directly incident on the illuminance sensor provided on the ceiling surface, or white paper with high light reflectance is placed directly under the illuminance sensor. In some cases, since the illuminance detected by the illuminance sensor is increased, the light may be dimmed in a direction that reduces the light output of the lighting device. For this reason, there is a problem that the actual desk top or floor surface is below the set illuminance.
このように照度センサに外光や高い照度の光が直接入射された場合に、机上や床面の照度を略一定に保つ照明制御装置が、例えば、特許文献1に提案されている。
For example,
特許文献1に提案されている照明制御装置は、照明負荷と、周囲照度を検知する照度センサと、照度センサの検知出力に応じて照明負荷の光出力を制御する制御部とを有する照明器具を複数備えた照明制御装置において、各照明器具の光出力の変化幅は、各々の照明器具の光出力を基に互いに略同一なる方向に再設定する。再設定する変化幅の調光下限レベルと調光上限レベルの少なくとも一方は、再設定前の各照明器具の光出力のうちの最大値もしくは最小値の少なくとも一方から得られるようにしている。
特許文献1に提案されている照明制御装置は、各々の照度センサが検知した照度に応じて照明負荷の光出力を制御する際に、光出力の変化幅を各々の照明器具の光出力を基に同一な方向に再設定している。即ち、光出力の変化幅を小さくして、光出力を平均値に近い範囲で制御している。
The lighting control device proposed in
一方、照度を略一定にする方法としては、複数の照明負荷からなる複数の照明系統毎に照度センサを設けて、照度センサにて検知した照度を平均化して、複数の照明系統の照明負荷の光出力を制御することも行われている。各照度センサが検知した照度を平均化して複数の照明系統の照明負荷の光出力を制御する方法は、例えば、ある照明系統の照明器具を消灯させた場合、各々の照度センサが検知した照度を平均化するために、消灯されている照明系統を補うように、点灯されている照明系統の照明負荷の光出力を増大させる制御が行われることになる。 On the other hand, as a method of making the illuminance substantially constant, an illuminance sensor is provided for each of a plurality of illumination systems composed of a plurality of illumination loads, the illuminance detected by the illuminance sensor is averaged, and the illumination loads of the plurality of illumination systems are Control of the light output is also performed. The method of averaging the illuminance detected by each illuminance sensor and controlling the light output of the illumination loads of multiple illumination systems is, for example, when the illuminator of a certain illumination system is turned off, the illuminance detected by each illuminance sensor is In order to average, control is performed to increase the light output of the lighting load of the lighting system that is turned on to compensate for the lighting system that is turned off.
つまり、各々の照度センサが検知した照度を平均化して複数の照明系統の光出力を制御させる場合は、ある照明系統のみを他の照明系統と異なる光出力に制御することはできなかった。又、特許文献1に提案されている照明制御装置には、ある照明系統を他の照明系統と異なる光出力に設定する場合については開示されてないが、前述した各々の照度センサが検知した照度を平均化する方法と略同じ制御となるものと思われる。
That is, when the illuminance detected by each illuminance sensor is averaged to control the light output of a plurality of illumination systems, it is not possible to control only a certain illumination system to a light output different from that of other illumination systems. Further, the illumination control device proposed in

本発明において用語の定義及び技術的意味は次による。 In the present invention, the definitions and technical meanings of terms are as follows.
照明系統は、照明ランプ、点灯回路、及び反射傘などからなる照明器具を一つ以上有する照明領域毎に区分して天井面に複数配置させ、照明領域毎の複数の照明器具を同一条件にて点灯調光制御する系列である。 The lighting system is divided into lighting areas each having one or more lighting fixtures composed of lighting lamps, lighting circuits, reflectors, etc., and arranged on the ceiling surface, and the plurality of lighting fixtures for each lighting area are under the same conditions. This is a series of lighting dimming control.
照度センサ付き調光手段は、照明器具からの光により照明される机上、床面、又は壁面から反射光の照度を検出する照度センサと、照度センサが検出した照度を基に、照明系統の調光を制御する調光器とが一体的に形成されている照度付き調光器である。又、子機照度センサは、反射光の照度を検出する機能のみを有している。つまり、照度センサ付き調光器の調光器には、自らの照度センサと子機照度センサが検出した照度が入力されると共に、入力された照度を基に複数の照明系統それぞれを調光制御するのものである。なお、照度センサ付き調光器には、照度センサ付き調光器の照度センサと子機照度センサがそれぞれ検出した照度の基で、複数の照明系統の調光度を設定するための調光度設定手段を有している。 The dimming means with an illuminance sensor adjusts the illumination system based on the illuminance sensor that detects the illuminance of the reflected light from the desk, floor, or wall surface illuminated by light from the luminaire and the illuminance detected by the illuminance sensor. It is a dimmer with illuminance in which a dimmer for controlling light is integrally formed. Moreover, the subunit | mobile_unit illuminance sensor has only the function to detect the illumination intensity of reflected light. In other words, the illuminance detected by its own illuminance sensor and slave illuminance sensor is input to the dimmer of the dimmer with the illuminance sensor, and dimming control is performed for each of the plurality of illumination systems based on the input illuminance. To do. The dimmer with the illuminance sensor has a dimming degree setting means for setting the dimming degree of a plurality of illumination systems based on the illuminance detected by the illuminance sensor and the slave illuminance sensor of the dimmer with the illuminance sensor. have.
目標照度は、照明系統毎に操作者によって設定される照度あり、照度センサ付き調光器の各照明系統毎の調光制御手段に対してリモートコントロール等にて目標照度となる調光度を設定する。 The target illuminance is the illuminance set by the operator for each illumination system, and the dimming degree to be the target illuminance is set by remote control or the like for the dimming control means for each illumination system of the dimmer with illuminance sensor. .
照度の重み付とは、目標照度が照明系統によって異なる場合に、ある照明系統の照度センサが検出した照度を基準にして、他の照明系統の調光度を設定する際に、ある照明系統の照度センサが検出した照度と他の照明系統の照度センサが検出した照度の比により照度に重み付けすることである。 The weighting of illuminance refers to the illuminance of a certain lighting system when setting the dimming degree of another lighting system based on the illuminance detected by the illuminance sensor of the certain lighting system when the target illuminance varies depending on the lighting system. The illuminance is weighted by the ratio of the illuminance detected by the sensor and the illuminance detected by the illuminance sensors of other illumination systems.
調光範囲は、照明器具の調光度の最大値(100)から最小値(0)の範囲の内、調光が最も顕著に制御できる範囲、例えば、調光度80〜30の範囲である。 The dimming range is a range in which dimming can be controlled most remarkably, for example, a range of dimming degree 80 to 30 in the range from the maximum value (100) to the minimum value (0) of the dimming degree of the lighting fixture.
照度の所定値とは、外光による反射光の有無に拘わらず、照明器具からの光による反射光の照度が検出できる最低照度である。 The predetermined value of the illuminance is the minimum illuminance at which the illuminance of the reflected light by the light from the lighting fixture can be detected regardless of the presence or absence of the reflected light by the external light.
本発明の照明制御装置は、照明系統毎に設定された目標照度に応じて安定した調光制御が行え、かつ、既存の照明系統にも容易に設置することができる効果を有している。 The illumination control device of the present invention has an effect that it can perform stable dimming control according to the target illuminance set for each illumination system, and can be easily installed in an existing illumination system.

本発明の一実施形態の照明制御装置は、図1に示すように、例えば、建物のあるフロアのそれぞれの照明領域を照明するための照明器具1a,1b,2a,2b,3a,3bが天井面に設けられている。なお、照明器具1a,1b,2a,2b,3a,3bは、単一の照明器具、もしくは、それぞれ複数の照明器具からなっている。 As shown in FIG. 1, the lighting control apparatus according to the embodiment of the present invention includes, for example, lighting fixtures 1a, 1b, 2a, 2b, 3a, and 3b for illuminating each lighting area of a floor with a ceiling.

Also good.
照明系統G1の照明器具1a,1bの近傍には、照明系統G1の照明領域からの反射光の照度を検出する照度センサを有すると共に、照明系統G1乃至照明系統G3のそれぞれの照明器具1a,1b,2a,2b,3a,3bを調光制御する調光器を有する照度センサ付き調光器S0(以下、親機S0と称する)が設けられている。照明系統G2の照明器具2a,2bと照明系統G3の照明器具3a,3bの近傍には、それぞれの照明領域G2,G3からの反射光の照度を検出する照度センサS1,S2(以下、子機照度センサS1,S2と称する)がそれぞれ設けられている。親機30の照度センサと子機照度センサS1,S2にて検出した照度は、親機S0の調光器に供給される。 In the vicinity of the luminaires 1a and 1b of the illumination system G1, there is an illuminance sensor that detects the illuminance of the reflected light from the illumination area of the illumination system G1, and each of the luminaires 1a and 1b of the illumination systems G1 to G3. , 2a, 2b, 3a, 3b is provided with a dimmer S0 with an illuminance sensor (hereinafter referred to as a master unit S0) having a dimmer for dimming control. Illumination sensors S1 and S2 (hereinafter referred to as slave units) for detecting the illuminance of the reflected light from the respective illumination areas G2 and G3 are provided in the vicinity of the illumination fixtures 2a and 2b of the illumination system G2 and the illumination fixtures 3a and 3b of the illumination system G3. Illuminance sensors S1 and S2) are provided. The illuminance detected by the illuminance sensor of the parent device 30 and the child device illuminance sensors S1, S2 is supplied to the dimmer of the parent device S0.
親機S0の調光器は、図示してないが、親機S0の照度センサと子機照度センサS1,S2から供給された照度を基に照明系統G1〜G3の調光度を設定し、照明系統G1〜G3の各照明器具1a,1b,2a,2b,3a,3bの調光制御を行う調光度設定手段が設けられている。また、親機S0の調光器は、図示してないリモートコントロール等により照明系統G1〜G3それぞれの目標の光出力、つまり、照明領域の目標照度が操作者によって設定できるようになっている。 Although not shown, the dimmer of the master unit S0 sets the dimming degree of the illumination systems G1 to G3 based on the illuminance supplied from the illuminance sensor of the master unit S0 and the slave unit illuminance sensors S1 and S2, Dimming degree setting means for performing dimming control of each of the lighting fixtures 1a, 1b, 2a, 2b, 3a, 3b of the systems G1 to G3 is provided. Further, the dimmer of the master unit S0 can set the target light output of each of the illumination systems G1 to G3, that is, the target illuminance of the illumination area, by an operator by a remote control (not shown).
即ち、親機S0の調光器は、操作者がリモートコントロール等にて設定した照明系統G1〜G3それぞれの目標照度となるように照度センサにて検出した照度を用いて調光制御する調光度設定手段を有している。 That is, the dimmer of the master unit S0 performs dimming control using the illuminance detected by the illuminance sensor so that the target illuminance of each of the illumination systems G1 to G3 set by the operator by remote control or the like is obtained. It has setting means.
又、本発明の一実施形態の照明制御装置は、既存の照明系統G1〜G3に対して、親機S0と子機照度センサS1,S2を設けることで調光制御可能な照明制御装置が構築できる。 In addition, the lighting control device according to the embodiment of the present invention is configured as a lighting control device capable of dimming control by providing the parent device S0 and the child device illuminance sensors S1 and S2 for the existing lighting systems G1 to G3. it can.
次に、本発明の一実施形態の照明制御装置の親機S0の調光器に設けられている調光度設定手段について、図2乃至図5を用いて説明する。親機S0の調光器に設けられる調光度設定手段は、照明系統G1〜G3の目標照度が同じ場合と、照明系統G1〜G3のいずれかの目標照度が異なる場合の調光制御方法を有する。 Next, dimming degree setting means provided in the dimmer of the parent device S0 of the lighting control apparatus according to the embodiment of the present invention will be described with reference to FIGS. The dimming degree setting means provided in the dimmer of the parent device S0 has a dimming control method when the target illuminance of the illumination systems G1 to G3 is the same and when the target illuminance of any of the illumination systems G1 to G3 is different. .
最初に、照明系統G1〜G3の目標照度が同じで、かつ、親機S0の調光器は、親機S0の照度センサが検出した照度のみを用いて照明系統G1〜G3を調光制御する動作状態の場合について、図2を用いて説明する。 First, the target illuminances of the illumination systems G1 to G3 are the same, and the dimmer of the parent device S0 performs dimming control on the illumination systems G1 to G3 using only the illuminance detected by the illuminance sensor of the parent device S0. The case of the operation state will be described with reference to FIG.
照明系統G1〜G3の目標照度が同じ、図2に示すように、例えば、親機S0の照度センサが検出した照明系統G1の照度1000レックス(Lx)、子機照度センサS1が検出した照明系統G2の照度1000Lx、及び子機照度センサS2が検出した照明系統G3の照度800Lxを検出して、検出された照度値が親機S0の調光器に供給されたとする。しかし、親機S0の調光器は、親機S0の照度センサが検出した照度1000Lxのみを用いて照明領域G1〜G3の調光を制御する動作状態に設定されている。このため、親機S0の調光器は、親機S0の照度センサが検出した照度1000Lxを基に照明系統G1〜G3の調光度を設定して同一調光となるように調光制御される。 As shown in FIG. 2, the illumination systems G1 to G3 have the same target illuminance. For example, the illumination system G1 detected by the illumination sensor G1 detects an illuminance of 1000 Rex (Lx), and the slave system illumination sensor S1 detects the illumination system. Assume that the illuminance 1000Lx of G2 and the illuminance 800Lx of the illumination system G3 detected by the slave device illuminance sensor S2 are detected, and the detected illuminance value is supplied to the dimmer of the master device S0. However, the dimmer of the parent device S0 is set to an operation state that controls the dimming of the illumination areas G1 to G3 using only the illuminance 1000Lx detected by the illuminance sensor of the parent device S0. For this reason, the dimmer of the master unit S0 is dimmed and controlled to set the dimming degree of the illumination systems G1 to G3 based on the illuminance 1000Lx detected by the illuminance sensor of the master unit S0. .
つまり、照明系統G1〜G3は、照度1000Lxとなるようにそれぞれの調光度が設定される。 That is, the dimming degrees of the illumination systems G1 to G3 are set so that the illuminance is 1000Lx.
次に、照明系統G1〜G3の目標照度が同じで、かつ、親機S0の調光器は、親機S0の照度センサと子機照度センサS1,S2が検出した照度により照明系統G1〜G3の調光制御する動作状態の場合について、図3を用いて説明する。 Next, the illumination system G1 to G3 has the same target illuminance, and the dimmer of the parent device S0 uses the illumination systems G1 to G3 according to the illuminance detected by the illuminance sensor of the parent device S0 and the child device illuminance sensors S1 and S2. The operation state in which the dimming control is performed will be described with reference to FIG.
照明系統G1〜G3の目標照度が同じで、図3に示すように、例えば、親機S0の照度センサが検出した照明系統G1の照度1000Lx、子機照度センサS1が検出した照明系統G2の照度1000Lx、及び子機照度センサS2が検出した照明系統G3の照度800Lxを検出して、検出された照度値が親機S0の調光器に供給されたとする。親機S0の調光器は、親機S0の照度センサと子機照度センサS1,S2がそれぞれが検出した照度の値を平均化(X)した平均照度を算出し、その平均照度を基に各照明系統G1〜G3の調光度を設定する。これにより、照明系統G1〜G3は、平均化された照度を基に算出された同一調光度により調光制御される。
The illumination system G1 to G3 have the same target illuminance, and as shown in FIG. 3, for example, the illumination system G1 detected by the illumination sensor G1 detects the illumination system 1000Lx, and the slave system illumination sensor S1 detects the illumination system G2 illumination. Assume that 1000 Lx and the
一方、図2を用いて説明した操作者が親機S0の調光器による各照明系統G1〜G3の調光を親機S0の照度センサのみが検出した照度を用いて行うよう操作者が設定したつもりが、設定ミスにより親機S0の調光器に子機照度センサS1,S2の検出照度も供給される場合もある。 On the other hand, the operator set using the illuminance detected by only the illuminance sensor of the parent device S0 is adjusted by the operator described with reference to FIG. 2 using the dimmer of the parent device S0. However, the detected illuminances of the handset illuminance sensors S1 and S2 may be supplied to the dimmer of the base unit S0 due to a setting error.
この場合、図3を用いて説明した、親機S0の調光器にて、親機S0の照度センサと子機照度センサS1,S2がそれぞれ検出した照明系統G1〜G3の照度を平均化して調光制御することで照明系統G1〜G3の安定した調光制御が行える。 In this case, the illuminances of the illumination systems G1 to G3 detected by the illuminance sensor of the master unit S0 and the slave unit illuminance sensors S1 and S2 are averaged by the dimmer of the master unit S0 described with reference to FIG. Dimming control enables stable dimming control of the illumination systems G1 to G3.
これは、既存の照明系統G1〜G3に親機S0と子機照度センサS1,S2を設置して照明制御装置を形成した際の親機S0の調光器の設定ミスを確実にカバーすることができる効果を有している。 This reliably covers the setting error of the dimmer of the master unit S0 when the master unit S0 and the slave unit illuminance sensors S1 and S2 are installed in the existing illumination systems G1 to G3 to form an illumination control device. Has the effect of
なお、照明領域G1〜G3の目標照度が同じに設定されている状態において、例えば、照明系統G3が消灯状態である場合は、照明系統G3の子機照度センサS2が検出する照度は外光等による非常の低い照度値となる。そこで、親機S0の調光器は、所定の照度値以下の照明系統G3の検出照度を除いて、照明系統G1,G2の照度を検出した親機S0の照度センサと子機照度センサS1からの照度値を用いて平均化して、照明系統G1,G2のみ調光制御させる。この結果、消灯状態の照明系統G3を補う調光制御を行うことなく、点灯状態のG1,G2の調光が可能となる。 In the state where the target illuminances of the illumination areas G1 to G3 are set to be the same, for example, when the illumination system G3 is in the extinguished state, the illuminance detected by the handset illuminance sensor S2 of the illumination system G3 is outside light or the like Due to the extremely low illuminance value. Therefore, the dimmer of the parent device S0 excludes the detected illuminance of the illumination system G3 having a predetermined illuminance value or less from the illuminance sensor of the parent device S0 and the child device illuminance sensor S1 that detect the illuminance of the illumination systems G1 and G2. The illuminance values are averaged, and only the illumination systems G1 and G2 are dimmed. As a result, it is possible to perform dimming of G1 and G2 in the lit state without performing dimming control to compensate for the illumination system G3 in the unlit state.
次に、操作者により照明系統G1〜G3それぞれの目標照度が異なる場合の親機S0の調光器の調光度設定手段による調光度設定について、図4と図5を用いて説明する。 Next, the dimming degree setting by the dimming degree setting means of the dimmer of the master unit S0 when the illumination systems G1 to G3 have different target illuminances depending on the operator will be described with reference to FIGS.
親機S0の調光器は、照明系統G1,G2は例えば執務場所で同じ明るさに設定され、照明系統G3は例えば、廊下で照明系統G1,G2よりも暗く設定されていたとする。こ目標照度に設定された状態において、親機S0の調光器は、執務場所を基準として、それぞれの照明系統G1〜G3の平均化制御を行う。照明系統G1〜g3はそれぞれの目標照度に設定されている状態において、図4に示すように、親機S0の照度センサは照明系統G1の照度1000Lxを検出し、子機照度センサS1は照明系統G2の照度1000Lxを検出し、及び子機照度センサS2は照明系統G3の照度800Lxを検出して、それぞれの照度が親機S0の調光器に供給される。親機S0の調光器は、執務室の照度を基準とするために、親機S0の照度センサと子機照度センサS1から供給された検出照度を平均化(X)して平均照度の状態の調光度を求める。この求められた調光度が50%(つまり、照明系統G1,G2の平均照度1000Lxの時の調光度)であるとする。親機S0の調光器は、照明系統G1,G2の平均照度と調光度50%を基に、照明系統G3の調光度を算出する。照明系統G3の調光度の算出は、照明系統G1,G2の平均照度と照明系統G3の照度比に照明系統G1,G2の調光度を乗算する(G3照度/G1,G2の平均照度×G1,G2調光度=800Lx/1000Lx×50%=40%)。この算出結果から、親機S0の調光器は、照明系統G1,G2は50%調光、照明系統G3は40%調光を行う。つまり、執務室の照明系統G1,G2の照度と、廊下の照明系統G3の照度との比によりそれぞれの調光度を設定する。 In the dimmer of the parent device S0, it is assumed that the illumination systems G1 and G2 are set to the same brightness in the office, for example, and the illumination system G3 is set to be darker than the illumination systems G1 and G2 in the hallway, for example. In the state set to this target illuminance, the dimmer of the parent device S0 performs the averaging control of the respective illumination systems G1 to G3 with reference to the work place. In the state where the illumination systems G1 to g3 are set to the respective target illuminances, as shown in FIG. 4, the illuminance sensor of the parent device S0 detects the illuminance 1000Lx of the illumination system G1, and the slave device illuminance sensor S1 is the illumination system. The illuminance 1000Lx of G2 is detected, and the child device illuminance sensor S2 detects the illuminance 800Lx of the illumination system G3, and each illuminance is supplied to the dimmer of the parent device S0. The dimmer of the master unit S0 is based on the illuminance in the office, and averages (X) the detected illuminance supplied from the illuminance sensor of the master unit S0 and the slave unit illuminance sensor S1 to obtain the average illuminance state. Obtain the dimming degree of It is assumed that the calculated dimming degree is 50% (that is, the dimming degree when the illumination systems G1 and G2 have an average illuminance of 1000 Lx). The dimmer of the parent device S0 calculates the dimming degree of the lighting system G3 based on the average illuminance of the lighting systems G1 and G2 and the dimming degree of 50%. The calculation of the dimming degree of the lighting system G3 is obtained by multiplying the average illuminance of the lighting systems G1 and G2 and the illuminance ratio of the lighting system G3 by the dimming degree of the lighting systems G1 and G2 (G3 illuminance / average illuminance of G1 and G2 × G1, G2 dimming degree = 800 Lx / 1000 Lx × 50% = 40%). From this calculation result, the dimmer of the parent device S0 performs 50% dimming for the illumination systems G1 and G2, and 40% dimming for the illumination system G3. That is, each dimming degree is set by the ratio of the illuminance of the lighting systems G1 and G2 in the office and the illuminance of the lighting system G3 in the hallway.
次に、図5を用いて廊下である照明系統G3の照度を基準にして、照明系統G1〜G3の平均調光制御について説明する。なお、照明系統G1〜G3の明るさ設定と検出照度は、図4と同じとする。 Next, the average dimming control of the illumination systems G1 to G3 will be described with reference to the illuminance of the illumination system G3, which is a corridor, with reference to FIG. Note that the brightness settings and the detected illuminance of the illumination systems G1 to G3 are the same as those in FIG.
基準とする照明系統G3の照度800Lxの調光度を40%であるとする。親機S0の調光器は、照明系統G3の照度800Lxの時の調光度40%を基に、照明系統G1,G2の調光度を算出する。照明系統G1,G2の調光度の算出は、照明系統G3の照度800Lxと照明系統G1,G2のそれぞれの照度1000Lxとの比に照明系統G3の調光度40%を乗算する(G1又はG2照度/G3の照度×G3調光度=1000Lx/800Lx×40%=50%)。この算出結果から、親機S0の調光器は、照明系統G1,G2は50%調光、照明系統G3は40%調光を行う。
It is assumed that the dimming degree of the illuminance 800Lx of the reference illumination system G3 is 40%. The dimmer of the parent device S0 calculates the dimming degree of the illumination systems G1 and G2 based on the dimming degree of 40% when the illumination system G3 has an illuminance of 800 Lx. The dimming degree of the illumination systems G1 and G2 is calculated by multiplying the ratio of the illuminance 800Lx of the illumination system G3 and the illuminance 1000Lx of each of the illumination systems G1 and G2 by the dimming
なお、ある照明系統の調光度を基準として他の照明系統の調光度を設定することは、照明器具の調光度の最大値(100)から最小値(0)の範囲の内、調光が最も顕著に制御できる範囲、例えば、調光度80〜30の範囲での調光制御が可能となる。 Note that setting the dimming degree of another lighting system on the basis of the dimming degree of a certain lighting system means that the dimming is the most within the range of the maximum dimming degree (100) to the minimum (0) of the lighting fixture. It is possible to perform dimming control in a range that can be remarkably controlled, for example, in the range of 80 to 30 dimming degrees.
つまり、照明系統に異なる目標照度が設定されている場合、照明系統毎に検出された照度に比較して照度に重み付けすることにより、それぞれの照明系統の目標照度での調光が可能となる。 That is, when different target illuminances are set for the illumination systems, the illuminance is weighted in comparison with the illuminance detected for each illumination system, thereby allowing dimming with the target illuminance of each illumination system.
以上説明したように、本発明の一実施形態の照明制御装置は、照明系統の目標照度が同じの場合に、照明系統毎に検出した照度を平均化することで、安定した調光制御が可能となる。又、目標照度が異なる照明系統がある場合には、基準照明系統の照度と他の照明系統の照度の重み付けにより照明系統の目標照度に応じた最適調光が可能となる。 As described above, the illumination control device according to an embodiment of the present invention can perform stable dimming control by averaging the illuminance detected for each illumination system when the target illuminance of the illumination system is the same. It becomes. Further, when there are illumination systems having different target illuminances, it is possible to perform optimum dimming according to the target illuminance of the illumination system by weighting the illuminance of the reference illumination system and the illuminance of other illumination systems.
なお、上述において、照明系統G1〜G3それぞれには、照明器具1a,1b,2a,2b,3a,3bが設けられ、各照明器具1a,1b,2a,2b,3a,3bは、単一または複数の照明器具の例を用いて説明したが、各照明系統G1〜G3は、複数の照明器具を有する必要はなく一つの照明器具でも良く、同一条件にて点灯、消灯及び調光の操作制御する対象の範囲を示している。 In addition, in the above-mentioned, each lighting system G1-G3 is provided with lighting fixtures 1a, 1b, 2a, 2b, 3a, 3b, and each lighting fixture 1a, 1b, 2a, 2b, 3a, 3b is single or Although it demonstrated using the example of several lighting fixtures, each lighting system | strain G1-G3 does not need to have several lighting fixtures, and may be one lighting fixture, and it is the operation control of lighting, light extinction, and light control on the same conditions.
