Hereinafter, lighting control devices according to a plurality of embodiments of the present invention will be described with reference to the drawings.
(First embodiment)
As shown in FIG. 1, the lighting control apparatus 10 according to the first embodiment of the present invention includes a switch element 11 that is a triac inserted between the lighting load LA and the commercial power supply AC, and the current of the commercial power supply AC.

And a signal processing unit 13 for performing

そして、照明制御装置10は、人体から放射される熱線を検出する熱線センサ14と、周囲照度を検出する明るさセンサ15と、熱線センサ14が人を検知した際に点灯状態を維持する時間を設定する点灯保持時間設定部16とを備える。

And a lighting holding time setting unit 16 to be set.
Furthermore, the illumination control device 10 includes a brightness sensor adjustment unit 17 that adjusts the brightness (illuminance) to be turned on according to the value of the brightness sensor 15.

信号処理部13は、明るさセンサ15による検出照度が基準照度を超えると、熱線センサ14の出力に関らず、スイッチ要素11をオフする。
そして、信号処理部13は、熱線センサ14の検知時における明るさセンサ15の値と、熱線センサ14が検知する一定時間前である10秒前の明るさセンサ15の値とを比較することにより、照明負荷LAの点灯状態を制御する。
なお、信号処理部13は、10秒前に限らず、任意の一定時間前の明るさセンサ15の値を用いることもできる。
When the illuminance detected by the brightness sensor 15 exceeds the reference illuminance, the signal processing unit 13 turns off the switch element 11 regardless of the output of the heat ray sensor 14.
Then, the signal processing unit 13 compares the value of the brightness sensor 15 at the time of detection by the heat ray sensor 14 with the value of the brightness sensor 15 before 10 seconds which is a certain time before the heat ray sensor 14 detects. The lighting state of the lighting load LA is controlled.
Note that the signal processing unit 13 is not limited to 10 seconds ago, but can use the value of the brightness sensor 15 before any given time.

次に、照明制御装置10の制御動作について、図2の状態図および図3の状態図を参照して図4のフローチャートを用いて説明する。
図2に示す状態Aにおいて、昼間に、窓WのあるトイレBR等の閉空間に人Hが侵入してくる場合、トイレBRに人Hが侵入してくる10秒前にトイレBR内は明るく、人HがドアXを開けてトイレBR内に侵入してきたときもトイレBR内は明るい。
Next, the control operation of the illumination control device 10 will be described using the flowchart of FIG. 4 with reference to the state diagram of FIG. 2 and the state diagram of FIG.
In the state A shown in FIG. 2, when a person H enters a closed space such as a toilet BR with a window W in the daytime, the toilet BR is brightened 10 seconds before the person H enters the toilet BR. When the person H opens the door X and enters the toilet BR, the inside of the toilet BR is bright.

すなわち、図4において、熱線センサ14により人Hが検知され、消灯中であり、10秒前の明るさセンサ15の値が基準照度を超えており、現在の明るさセンサ15の値が基準照度を超えている。
そのため、照明負荷LAを消灯状態とする(S101→S102→S103→S104→S105)。
That is, in FIG. 4, the person H is detected by the heat ray sensor 14 and is turned off, the value of the brightness sensor 15 10 seconds ago exceeds the reference illuminance, and the current value of the brightness sensor 15 is the reference illuminance. Is over.
Therefore, the illumination load LA is turned off (S101 → S102 → S103 → S104 → S105).

図2に示す状態Bにおいて、日が暮れる瞬間において、窓WのあるトイレBRに続く廊下P等の照明が消灯されていて、人HがドアXを開けてトイレBR内に侵入してきた場合、トイレBRに人Hが侵入してくる10秒前にトイレBR内は明るい。
そして、周囲は明るい状態から暗い状態になりつつあるために、人HがドアXを開けてトイレBR内に侵入してきたときにトイレBR内は暗い。
In the state B shown in FIG. 2, at the moment when the sun goes down, when the lights such as the corridor P following the toilet BR with the window W are turned off and the person H opens the door X and enters the toilet BR, The toilet BR is bright 10 seconds before the person H enters the toilet BR.
Since the surroundings are changing from a bright state to a dark state, when the person H opens the door X and enters the toilet BR, the inside of the toilet BR is dark.

すなわち、図4において、熱線センサ14により人Hが検知され、消灯中であり、10秒前の明るさセンサ15の値が基準照度を超えており、現在の明るさセンサ15の値が基準照度を下回っている。
そのため、照明負荷LAを点灯させ、点灯保持時間設定部16により保持時間が設定される(S101→S102→S103→S104→S106→S107)。
That is, in FIG. 4, the person H is detected by the heat ray sensor 14 and is turned off, the value of the brightness sensor 15 10 seconds ago exceeds the reference illuminance, and the current value of the brightness sensor 15 is the reference illuminance. Is below.
Therefore, the illumination load LA is turned on, and the holding time is set by the lighting holding time setting unit 16 (S101 → S102 → S103 → S104 → S106 → S107).

図3に示す状態Cにおいて、夜間に、廊下Pの照明が点灯されていて、人HがドアXを開けて窓WのないトイレBR内に侵入してきた場合、トイレBRに人Hが侵入してくる10秒前にトイレBR内は暗い。
そして、人HがドアXを開けてトイレBR内に侵入してきたときにトイレBR内が明るくなる。
In the state C shown in FIG. 3, at night, when the lighting of the corridor P is turned on and the person H opens the door X and enters the toilet BR without the window W, the person H enters the toilet BR. Toilet BR is dark 10 seconds before coming.
When the person H opens the door X and enters the toilet BR, the inside of the toilet BR becomes bright.

すなわち、図4において、熱線センサ14により人Hが検知され、消灯中であり、10秒前の明るさセンサ15の値が基準照度を下回っており、現在の明るさセンサ15の値が基準照度を超えている。
そのため、照明負荷LAを全点灯させ、点灯保持時間設定部16により保持時間が設定される(S101→S102→S103→S108→S109→S107)。
That is, in FIG. 4, the person H is detected by the heat ray sensor 14 and is turned off, the value of the brightness sensor 15 10 seconds ago is lower than the reference illuminance, and the current value of the brightness sensor 15 is the reference illuminance. Is over.
Therefore, the lighting load LA is fully lit, and the holding time is set by the lighting holding time setting unit 16 (S101 → S102 → S103 → S108 → S109 → S107).

図3に示す状態Dにおいて、夜間に、睡眠中の人HがトイレBRに行きたくなった場合、周囲が暗く、目が暗さに慣れているために、暗いままで人HがドアXを開けて窓WのないトイレBR内に侵入する。
この場合、トイレBRに人Hが侵入してくる10秒前にトイレBR内は暗く、人HがドアXを開けてトイレBR内に侵入してきたときにトイレBR内が暗い。
In the state D shown in FIG. 3, when the sleeping person H wants to go to the toilet BR at night, the person H uses the door X in the dark state because the surroundings are dark and his eyes are used to darkness. Open and enter the toilet BR without the window W.
In this case, the inside of the toilet BR is dark 10 seconds before the person H enters the toilet BR, and the inside of the toilet BR is dark when the person H opens the door X and enters the toilet BR.

すなわち、図4において、熱線センサ14により人Hが検知され、消灯中であり、10秒前の明るさセンサ15の値が基準照度を下回っており、現在の明るさセンサ15の値が基準照度を下回っている。
そのため、人Hの目が暗さに慣れているので、照明負荷LAを調光点灯させ、点灯保持時間設定部16により保持時間が設定される(S101→S102→S103→S108→S110→S107)。
なお、点灯保持時間設定部16は、人Hがいなくなってから、設定された保持時間がタイムアップしたか否かを判別するルーチンを繰り返し実行する(S101→S111)。
That is, in FIG. 4, the person H is detected by the heat ray sensor 14 and is turned off, the value of the brightness sensor 15 10 seconds ago is lower than the reference illuminance, and the current value of the brightness sensor 15 is the reference illuminance. Is below.
Therefore, since the eyes of the person H are used to darkness, the lighting load LA is dimmed and the holding time is set by the lighting holding time setting unit 16 (S101 → S102 → S103 → S108 → S110 → S107). .
The lighting holding time setting unit 16 repeatedly executes a routine for determining whether or not the set holding time has expired after the person H disappears (S101 → S111).

図3に示す状態Cと同様に、夜間に、廊下Pの照明が点灯されていて、人Hが起きていて活動している時間帯では、人Hの目は明るさに慣れている。
そして、人HがドアXを開けて窓WのないトイレBR内に侵入してきた場合、トイレBRに人Hが侵入してくる10秒前にトイレBR内は暗く、人HがドアXを開けてトイレBR内に侵入してきたときにトイレBR内が明るくなる。
As in the state C shown in FIG. 3, the eyes of the person H are accustomed to the brightness in the time zone when the lighting of the corridor P is turned on at night and the person H is awake and active.
Then, when the person H opens the door X and enters the toilet BR without the window W, the toilet BR is dark and the person H opens the door X 10 seconds before the person H enters the toilet BR. When the toilet BR has entered the toilet BR, the toilet BR becomes brighter.

すなわち、図4において、熱線センサ14により人Hが検知され、消灯中であり、10秒前の明るさセンサ15の値が基準照度を下回っており、現在の明るさセンサ15の値が基準照度を超えている。
そのため、照明負荷LAを全点灯させ、点灯保持時間設定部16により保持時間が設定される(S101→S102→S103→S108→S109→S107)。
That is, in FIG. 4, the person H is detected by the heat ray sensor 14 and is turned off, the value of the brightness sensor 15 10 seconds ago is lower than the reference illuminance, and the current value of the brightness sensor 15 is the reference illuminance. Is over.
Therefore, the lighting load LA is fully lit, and the holding time is set by the lighting holding time setting unit 16 (S101 → S102 → S103 → S108 → S109 → S107).

図3に示す状態Dと同様に、夜間に、睡眠中の人HがトイレBRに行きたくなった場合、周囲が暗く、目が暗さに慣れているために、暗いままで人HがドアXを開けて窓WのないトイレBR内に侵入する。
この場合、トイレBRに人Hが侵入してくる10秒前にトイレBR内は暗く、人HがドアXを開けてトイレBR内に侵入してきたときにトイレBR内が暗い。
As in the state D shown in FIG. 3, when the sleeping person H wants to go to the toilet BR at night, the surroundings are dark and the eyes are used to darkness. Open X and enter the toilet BR without the window W.
In this case, the inside of the toilet BR is dark 10 seconds before the person H enters the toilet BR, and the inside of the toilet BR is dark when the person H opens the door X and enters the toilet BR.

すなわち、図4において、熱線センサ14により人Hが検知され、消灯中であり、10秒前の明るさセンサ15の値が基準照度を下回っており、現在の明るさセンサ15の値が基準照度を下回っている。
そのため、人Hの目が暗さに慣れているので、照明負荷LAを調光点灯させ、点灯保持時間設定部16により保持時間が設定される(S101→S102→S103→S108→S110→S107)。
That is, in FIG. 4, the person H is detected by the heat ray sensor 14 and is turned off, the value of the brightness sensor 15 10 seconds ago is lower than the reference illuminance, and the current value of the brightness sensor 15 is the reference illuminance. Is below.
Therefore, since the eyes of the person H are used to darkness, the lighting load LA is dimmed and the holding time is set by the lighting holding time setting unit 16 (S101 → S102 → S103 → S108 → S110 → S107). .

次に、照明制御装置10の変形例の制御動作について説明する。
図5に示すように、状態Eにおいて、日が暮れる瞬間において、トイレBRに続く廊下P等の照明が消灯されていて、人HがドアXを開けてトイレBR内に侵入してきた場合、トイレBRに人Hが侵入してくる10秒前にトイレBR内は明るい。
そして、周囲は明るい状態から暗い状態になりつつあるために、人HがドアXを開けてトイレBR内に侵入してきたときにトイレBR内は暗い。
Next, a control operation of a modified example of the illumination control device 10 will be described.
As shown in FIG. 5, in the state E, at the moment when the sun goes down, if the lights such as the corridor P following the toilet BR are turned off and the person H opens the door X and enters the toilet BR, The toilet BR is bright 10 seconds before the person H enters BR.
Since the surroundings are changing from a bright state to a dark state, when the person H opens the door X and enters the toilet BR, the inside of the toilet BR is dark.

すなわち、熱線センサ14により人Hが検知され、消灯中であり、10秒前の明るさセンサ15の値が基準照度を超えており、現在の明るさセンサ15の値が基準照度を下回っている。
