Therefore, when there is no moving body indoors, it does not become pitch black, and a person who tries to enter the building can visually check his / her feet and the like, and can ensure the safety of the person. Further, according to the present invention, when the sensor detects a moving body, the main lighting command unit transmits a lighting command signal to the main light, and when the sensor does not detect the moving body, the auxiliary lighting command unit is an auxiliary light. It is possible to give a lighting command to. Therefore, the main light irradiates only the place where the moving body passes, and the auxiliary light having low luminous intensity and low electricity cost can be turned on in the place where the moving body does not pass. Therefore, the electricity bill of the building can be further reduced. Further, when the main light is turned on by the main lighting command unit, the electricity bill of the building can be further reduced by turning off the auxiliary light by the auxiliary turning off command unit. That is, according to the present invention, the safety of a building such as a factory can be further improved, and the electricity cost of the building can be further reduced.

In FIGS. 1 and 2, reference numeral 10 indicates the lighting device of the present invention. In FIG. 1, solid lines connecting devices, devices, controllers or parts show that they are connected or related to each other. Devices, devices, controllers or parts are controlled by a computer (not shown). The computer includes a CPU, memory, and input / output ports. The device or the like may be controlled by an electric circuit without a CPU.

（構成）
照明装置１０は、図１及び図２に示すように、人又はフォークリフト等の移動体を検知できるセンサー１２を備える。センサー１２の赤外線受信面４０は、球体の一部の形状を有する。赤外線受信面４０を下に向けて照明装置１０を天井に設置した場合、センサー１２の検知範囲は平面視で円形である。センサー１２は、人等から生じる赤外線を検知できる。センサー１２は、人等が移動することにより生じた赤外線の変化を、移動体有として検知できる。センサー１２は、移動体を検知できる超音波センサーであってもよい。 (Constitution)
As shown in FIGS. 1 and 2, the lighting device 10 includes a sensor 12 capable of detecting a person or a moving object such as a forklift. The infrared receiving surface 40 of the sensor 12 has the shape of a part of a sphere. When the lighting device 10 is installed on the ceiling with the infrared receiving surface 40 facing downward, the detection range of the sensor 12 is circular in a plan view. The sensor 12 can detect infrared rays generated by a person or the like. The sensor 12 can detect a change in infrared rays caused by the movement of a person or the like as a moving body. The sensor 12 may be an ultrasonic sensor capable of detecting a moving body.

照明装置１０は、図１及び図２に示すように、照明装置１０を構成する機器を制御するコントローラー１６を備える。コントローラー１６の内部構成は、後で詳細に説明する。コントローラー１６は、センサー１２と接続されている。コントローラー１６は、工場等の建築物５０の天井５２（図５に示す）に予め配置されている主要灯１４に接続できるように構成されている。主要灯１４の種類は、ＬＥＤ電灯又は白熱電灯等、特に限定されない。 As shown in FIGS. 1 and 2, the lighting device 10 includes a controller 16 that controls the devices constituting the lighting device 10. The internal configuration of the controller 16 will be described in detail later. The controller 16 is connected to the sensor 12. The controller 16 is configured to be able to connect to a main light 14 arranged in advance on the ceiling 52 (shown in FIG. 5) of a building 50 such as a factory. The type of the main lamp 14 is not particularly limited, such as an LED lamp or an incandescent lamp.

照明装置１０は、図１及び図２に示すように、コントローラー１６に接続された補助灯１８を備える。補助灯１８の照射面４２は長方形であり、照明装置１０を天井に設置した場合、補助灯１８の照射範囲は円形又は楕円等である。補助灯１８とコントローラー１６とは、一体であり、照明装置１０を把持して主要灯１４に接続する作業が容易なように構成されている。照射面４２は透明ではなく透光性を有する白色である。補助灯１８が照射する光の光度は、主要灯１４が照射する光の光度よりも低く、好ましくは０．５倍以下、さらに好ましくは０．２５倍以下であることが望ましい。コントローラー１６は、補助灯１８の光度を設定できるように構成してもよい。補助灯１８は人等の移動体が存在しない時に点灯させるものであるため、光度を低くして乱反射により広い範囲を照射できるようにするためである。補助灯１８の消費電力は、主要灯１４の消費電力よりも少なく、好ましくは０．２５倍以下であることが望ましい。補助灯１８は、人等の移動体が存在しない夜間等に長時間点灯することがあるため、補助灯１８は、電気代の安いＬＥＤ電灯であることが好ましい。 As shown in FIGS. 1 and 2, the lighting device 10 includes an auxiliary light 18 connected to the controller 16. The irradiation surface 42 of the auxiliary light 18 is rectangular, and when the lighting device 10 is installed on the ceiling, the irradiation range of the auxiliary light 18 is circular, elliptical, or the like. The auxiliary light 18 and the controller 16 are integrated, and are configured so that the work of grasping the lighting device 10 and connecting to the main light 14 can be easily performed. The irradiation surface 42 is not transparent but white with translucency. The luminous intensity of the light emitted by the auxiliary lamp 18 is lower than the luminous intensity of the light emitted by the main lamp 14, preferably 0.5 times or less, and more preferably 0.25 times or less. The controller 16 may be configured so that the luminous intensity of the auxiliary light 18 can be set. Since the auxiliary light 18 is turned on when there is no moving body such as a person, the luminous intensity is lowered so that a wide range can be irradiated by diffused reflection. The power consumption of the auxiliary light 18 is less than the power consumption of the main light 14, preferably 0.25 times or less. Since the auxiliary light 18 may be lit for a long time at night when there is no moving body such as a person, the auxiliary light 18 is preferably an LED lamp having a low electricity bill.

（コントローラー１６）
コントローラー１６は、図２に示す電線４４から交流の電気が供給される電気受給部（図示しない）を備える。コントローラー１６は、電気コード４６を介して主要灯１４に交流の電気を供給する電気供給部（図示しない）を備える。 (Controller 16)
The controller 16 includes an electricity receiving unit (not shown) to which alternating current electricity is supplied from the electric wire 44 shown in FIG. The controller 16 includes an electric supply unit (not shown) that supplies alternating current electricity to the main light 14 via the electric cord 46.

コントローラー１６は、図１に示すように、センサー１２の検知信号を受信する信号受信部２０を備える。コントローラー１６は、信号受信部２０が受信した検知信号に基づいて、人等の移動体の有無を判断する判断部２２を備える。判断部２２は、信号受信部２０から受信した信号を２値化処理し、移動体有又は移動体無を判断する。コントローラー１６は、判断部２２が移動体有と判断した場合に、補助灯１８に消灯指令する補助消灯指令部２４を備える。また、コントローラー１６は、判断部２２が移動体有と判断した場合に、主要灯１４に点灯指令する主要点灯指令部２６を備える。 As shown in FIG. 1, the controller 16 includes a signal receiving unit 20 that receives the detection signal of the sensor 12. The controller 16 includes a determination unit 22 that determines the presence or absence of a moving body such as a person based on the detection signal received by the signal reception unit 20. The determination unit 22 binarizes the signal received from the signal reception unit 20 and determines whether or not there is a moving body. The controller 16 includes an auxiliary light-off command unit 24 that commands the auxiliary light 18 to turn off when the determination unit 22 determines that the moving body is present. Further, the controller 16 includes a main lighting command unit 26 that gives a lighting command to the main light 14 when the determination unit 22 determines that the moving body is present.

コントローラー１６は、判断部２２が移動体有と判断した場合に、補助灯１８の消灯を開始するための遅れ時間を記憶する遅れ時間記憶部３２と、遅れ時間に基づいて（関係付けして）補助消灯指令部２４と主要点灯指令部２６とを連動処理させる遅れ処理部３４と、を備える。遅れ時間は、予め設定されている。遅れ処理部３４は、主要点灯指令部２６が主要灯１４に点灯指令したことを認識した後、遅れ時間の経過の時に、補助消灯指令部２４に、補助灯１８に消灯指令させるように構成されている。すなわち、遅れ処理部３４は、判断部２２が移動体有と判断した場合、図３及び図４に示すように、主要灯１４を点灯させた後、遅れ時間が経過した後に、補助灯１８を消灯させるように構成されている。遅れ時間は、例えば、０．５秒、１．０秒又は１．５秒である。このため、照明装置１０を設置している屋内が完全に消灯して人が足元等を目視できない瞬間が生じることがなく、屋内の安全性が向上する。また、補助灯１８が消灯するのと同時に光の強い主要灯１４が点灯することによって、目に強いショックを与えることがない。 The controller 16 has a delay time storage unit 32 that stores a delay time for starting turning off the auxiliary light 18 when the determination unit 22 determines that the moving body is present, and the controller 16 is based on (related to) the delay time. A delay processing unit 34 that interlocks the auxiliary light-off command unit 24 and the main lighting command unit 26 is provided. The delay time is preset. The delay processing unit 34 is configured to cause the auxiliary light-off command unit 24 to command the auxiliary light 18 to turn off when the delay time elapses after recognizing that the main lighting command unit 26 has given a lighting command to the main light 14. ing. That is, when the determination unit 22 determines that the moving body is present, the delay processing unit 34 turns on the main light 14 and then turns on the auxiliary light 18 after the delay time elapses, as shown in FIGS. 3 and 4. It is configured to turn off. The delay time is, for example, 0.5 seconds, 1.0 seconds or 1.5 seconds. Therefore, the indoor safety in which the lighting device 10 is installed is not completely turned off and a person cannot see his / her feet or the like, and the indoor safety is improved. Further, since the main light 14 having strong light is turned on at the same time as the auxiliary light 18 is turned off, a strong shock to the eyes is not given.

コントローラー１６は、図１に示すように、主要灯１４の点灯を継続する点灯継続時間を記憶する継続時間記憶部３６を備える。点灯継続時間は、リモコン（図示しない）から設定できる。点灯継続時間は、例えば、３０秒、１分、３分又は５分である。コントローラー１６は、主要灯１４が点灯した後、点灯継続時間が経過することに関係付けして、補助灯１８に点灯指令する補助点灯指令部２８を備える。コントローラー１６は、主要灯１４が点灯した後に、点灯継続時間が経過した時、主要灯１４に消灯指令する主要消灯指令部３０を備える。 As shown in FIG. 1, the controller 16 includes a duration storage unit 36 that stores a lighting duration for continuing lighting of the main lamp 14. The lighting duration can be set from a remote controller (not shown). The lighting duration is, for example, 30 seconds, 1 minute, 3 minutes, or 5 minutes. The controller 16 includes an auxiliary lighting command unit 28 that gives a lighting command to the auxiliary light 18 in relation to the elapse of the lighting duration after the main light 14 is turned on. The controller 16 includes a main turn-off command unit 30 that gives a turn-off command to the main light 14 when the lighting duration elapses after the main light 14 is turned on.

コントローラー１６は、点灯継続時間よりも短時間の先行時間を記憶する先行時間記憶部３８を備える。先行時間は、点灯継続時間から、予め先行時間記憶部３８に設定されている偏差時間を差し引いて、先行時間記憶部３８に記憶される。コントローラー１６は、先行時間に基づいて（関係付けして）補助点灯指令部２８と主要消灯指令部３０とを連動処理させる先行処理部３５を備える。先行処理部３５は、主要点灯指令部２６が主要灯１４に点灯指令し主要灯が点灯１４した後、判断部２２が移動体無と判断した場合に、先行時間の終了の時に、補助点灯指令部２８に、点灯指令させるように構成されている。主要消灯指令部３０は、先行時間よりも長時間の点灯継続時間が終了する時に、主要灯１４を消灯させるように構成されている。すなわち、先行処理部３５は、図３及び図４に示すように、主要灯１４が点灯してから消灯するまでの時間と、補助灯１８が消灯してから点灯するまでの時間との間に偏差時間を設けている。偏差時間は、例えば、０．５秒、０．７秒、又は１．５秒等である。このため、照明装置１０を設置している屋内が完全に消灯して人が足元等を目視できない瞬間が生じることがなく、屋内の安全性が向上する。 The controller 16 includes a preceding time storage unit 38 that stores a preceding time shorter than the lighting duration. The preceding time is stored in the preceding time storage unit 38 by subtracting the deviation time set in advance in the preceding time storage unit 38 from the lighting duration. The controller 16 includes a preceding processing unit 35 that interlocks (associates) the auxiliary lighting command unit 28 and the main turning off command unit 30 based on the preceding time. The advance processing unit 35 gives an auxiliary lighting command at the end of the preceding time when the determination unit 22 determines that there is no moving body after the main lighting command unit 26 gives a lighting command to the main light 14 and the main light 14 is turned on. The unit 28 is configured to give a lighting command. The main light-off command unit 30 is configured to turn off the main light 14 when the lighting duration longer than the preceding time ends. That is, as shown in FIGS. 3 and 4, the advance processing unit 35 takes between the time from when the main light 14 is turned on to when it is turned off and the time when the auxiliary light 18 is turned off until it is turned on. A deviation time is provided. The deviation time is, for example, 0.5 seconds, 0.7 seconds, 1.5 seconds, or the like.

And keep it off.

（照明装置１０、照明ユニット５８及び照明システム４８の通常稼働）
建築物５０の屋内６４に人５６等の移動体が存在しない場合、センサー１２が移動体を検知しないため、図３に示すように、補助灯１８が点灯し主要灯１４が消灯した状態が維持される。このため、屋内６４は、移動体が存在しなくとも真っ暗になることはなく、補助灯１８が点灯している状態となる。 (Normal operation of lighting device 10, lighting unit 58, and lighting system 48)
When there is no moving object such as a person 56 in the indoor 64 of the building 50, the sensor 12 does not detect the moving object. Therefore, as shown in FIG. 3, the auxiliary light 18 is turned on and the main light 14 is turned off. Will be done. Therefore, the indoor 64 does not become pitch black even if there is no moving body, and the auxiliary light 18 is lit.

例えば、図５に示すように、フォークリフト５４に乗車した人５６が屋内６４に入り移動する場合、人５６又はフォークリフト５４を移動体としてセンサー１２が検知した照明ユニット５８においては、図３に示すように、主要灯１４を点灯し、遅れ時間の時間待ちを行った後、補助灯１８を消灯する。そして、主要灯が点灯１４した後、判断部２２が移動体無と判断した場合に、照明ユニット５８は、先行時間（例えば、２９．３秒）の時間待ちを行って補助灯１８を点灯した後、主要灯１４が消灯する。主要灯１４は、点灯継続時間（例えば３０秒）の経過の時に消灯することになる。人５６をセンサー１２が検知しない照明ユニット５８においては、照明装置１０の主要灯１４が消灯し補助灯１８が点灯する。フォークリフト５４に乗車した人５６が屋内６４に存在しなくなっても、作業者が存在する時、作業者を移動体としてセンサー１２が検知した照明ユニット５８においては、図３に示すように、主要灯１４を点灯し、遅れ時間の時間待ちを行った後、補助灯１８を消灯する。 For example, as shown in FIG. 5, when the person 56 riding on the forklift 54 enters the indoor 64 and moves, the lighting unit 58 detected by the sensor 12 with the person 56 or the forklift 54 as a moving body is as shown in FIG. The main light 14 is turned on, the auxiliary light 18 is turned off after waiting for the delay time. Then, when the determination unit 22 determines that there is no moving body after the main light is turned on 14, the lighting unit 58 waits for a preceding time (for example, 29.3 seconds) and turns on the auxiliary light 18. After that, the main light 14 is turned off. The main light 14 will be turned off when the lighting duration (for example, 30 seconds) has elapsed. In the lighting unit 58 in which the sensor 12 does not detect the person 56, the main light 14 of the lighting device 10 is turned off and the auxiliary light 18 is turned on. Even if the person 56 who got on the forklift 54 does not exist in the indoor 64, in the lighting unit 58 where the sensor 12 detects the worker as a moving body when the worker exists, as shown in FIG. 3, the main light 14 is turned on, and after waiting for a delay time, the auxiliary light 18 is turned off.

本願発明によれば、上述のように、屋内６４に人５６等の移動体が存在しない場合、屋内６４は、真っ暗になることはなく、補助灯１８が点灯している状態となるため、建築物５０に入ろうとする人５６は足元等を目視でき、人の安全を確保することができる。また、本願発明によれば、建築物５０の外部の安全のために建築物５０の窓から光が外部へ漏れる常夜灯として利用することもできる。また、本願発明によれば、人５６が通過する場所のみに主要灯１４により光を照射し、人５６が通過しない場所は、光度が低くて電気代の安い補助灯１８を点灯することができる。このため、建築物５０の電気代をより低減できる。すなわち、本願発明によれば、工場等の建築物５０の安全性をより向上させることができるとともに、建築物５０の電気代をより低減できる。 According to the present invention, as described above, when there is no moving body such as a person 56 in the indoor 64, the indoor 64 is not completely dark and the auxiliary light 18 is lit. The person 56 who tries to enter the object 50 can visually check his / her feet and the like, and can ensure the safety of the person. Further, according to the present invention, it can also be used as a nightlight in which light leaks to the outside from the window of the building 50 for the safety of the outside of the building 50. Further, according to the present invention, the main light 14 irradiates only the place where the person 56 passes, and the auxiliary light 18 having a low luminous intensity and a low electricity cost can be turned on at the place where the person 56 does not pass. .. Therefore, the electricity bill of the building 50 can be further reduced. That is, according to the present invention, the safety of the building 50 such as a factory can be further improved, and the electricity cost of the building 50 can be further reduced.
