図１及び図２において、照明装置は４つの照明器具１とリモコン１０とで構成されている。
各照明器具１は、ランプ２とランプ２を点灯制御する照明器具コントローラ３とで構成されている。その照明器具１には分電盤４から配線された電灯線５が接続されている。また、分電盤４には他電力消費設備６が接続されている。

なお、赤外線信号受信部２２は赤外線受信素子を含む回路で構成され、ＣＰＵ２３はパソコンで構成され、表示部２４はＣＲＴ等であり、記憶部２５はＲＡＭ、ＨＤＤ等の記憶素子／媒体で形成され、操作部２６は例えばキーボード等であり、赤外線信号送信部２７は赤外線送信素子を含む回路で構成され、外部入出力部２８はＲＳ−２３２Ｃやイーサネット（登録商標）等で構成され、記録出力部２９は例えばプリンタやペンレコーダ等記録計等であり、タイマ部３０は時刻を計時する時計である。また、集中制御装置３１はビルの部屋、階又はビル全体の照明器具を集中管理し、制御するものである。
【００１３】
次に、本発明の実施の形態に係る照明装置状態監視システムの動作について説明する。
まず、その前にリモコン１０を用いて例えば４つの照明器具１に対して行う調光制御について説明する。
ここではリモコン１０により４つの照明器具１が所定の調光率で点灯制御され、それ以降に調光率を代える場合について説明する。
例えば、リモコン１０の赤外線送信部１６より、特定のアドレス４の照明器具１の照明器具コントローラ３に対して、調光制御情報である例えば光出力ＵＰの指令を赤外線信号で送信するときには、送信される赤外線信号に、さらにＵＰさせるべき照明器具のアドレス情報を付与する。このとき、リモコン１０から送信する赤外線信号はアドレス４の照明器具１の照明器具コントローラ３ではなく、アドレス１の照明器具１の照明器具コントローラ３に向けて送信したとする。
ここで、アドレス１の照明器具１の照明器具コントローラ３は受信した赤外線信号が自分自身（アドレス１）に対する指令ではないことを器具制御部１２で判断し、ランプの光出力を増加させる制御は行わず、その受信した赤外線信号と同じ内容の赤外線信号を器具赤外線送信部１４から送信する。
【００１４】
次に、アドレス１の照明器具１の照明器具コントローラ３から送信された赤外線信号は、直接もしくは床面の反射によってアドレス２の照明器具１の照明器具コントローラ３で受信される。アドレス２の照明器具１の照明器具コントローラ３は前述のアドレス１の照明器具１の照明器具コントローラ３と同様に、自分自身に対する指令でないことから、その受信した赤外線信号と同じ内容の赤外線信号を器具赤外線送信部１４から送信する。同様にアドレス２から送信された赤外線信号はアドレス３の照明器具１で受信されるが、ここも同様に自分自身に対する指令でないことから、その受信した赤外線信号と同じ内容の赤外線信号を器具赤外線送信部１４から送信する。
【００１５】
次に、アドレス３の照明器具１の照明器具コントローラ３が送信した赤外線信号をアドレス４の照明器具１の照明器具コントローラ３が受信した場合は、受信した赤外線信号は自分自身（アドレス４）に対する指定であることから、受信した赤外線信号を器具制御部１２で解読処理し、アドレス４の照明器具１の光出力を増加するよう点灯回路部１１を制御する。このとき、動作検出部１２ａで出力しているランプ２の光出力の度合いを示す調光率が検出され、アドレス４の照明器具１の照明器具コントローラ３の記憶部１３には、出力しているランプの光出力の度合いを示す調光率が記憶格納される。
【００１６】
次に、リモコン１０からアドレス４の照明器具１の動作情報、ここでは例えば、現在の点灯しているランプ２の調光率がいくつなのかを要求する赤外線信号がリモコン１０の赤外線信号送信部１６から送信された場合、リモコン１０から送信された赤外線信号がアドレス１の照明器具１の照明器具コントローラ３で受信された場合は、自分自身（アドレス１）に対する要求ではないことを器具制御部１２で判断し、器具赤外線受信部１５で受信した赤外線信号と同じ内容の赤外線信号を器具赤外線送信部１４が送信する。ここで、この赤外線信号をアドレス２の照明器具１の照明器具コントローラ３が受信したとすると、アドレス１の照明器具１が受信した場合と同様に受信した赤外線信号と同じ内容の赤外線信号を送信する。さらに、アドレス３の器具が受信した場合も同様である。
【００１７】
この赤外線信号をアドレス４の照明器具１の照明器具コントローラ３が受信した場合、自分自身（アドレス４）に対する要求であることから、アドレス４の照明器具１の照明器具コントローラ３は記憶部１３に記憶格納している調光率を器具制御部１２で読み出し、器具赤外線送信部１４よりリモコン１０へリモコン１０のアドレス０としたアドレス情報と調光率情報を付与した赤外線信号を送信する。
アドレス４の照明器具１の照明器具コントローラ３より送信された、調光率情報を付与した赤外線信号は、アドレス３の照明器具１の照明器具コントローラ３で受信された場合、自分自身（アドレス３）への指令信号ではなくリモコン１０に対する信号であると器具制御部１２で判断し、受信した赤外線信号と同じ内容の赤外線信号を送信する。以下同様にアドレス２の照明器具、アドレス１の照明器具が受信した場合でも自分自身に対する指令信号ではないことから、受信した赤外線信号と同様の赤外線信号を送信する。
【００１８】
そして、リモコン１０が赤外線受信部１７で、アドレス４の照明器具１の照明器具コントローラ３が送信した調光率情報を付与した赤外線信号を受信し、又は他のアドレスの照明器具を経由したアドレス４の照明器具１の照明器具コントローラ３が送信したアドレス情報と調光率情報を付与した赤外線信号を受信した場合には、アドレス情報が自分自身のアドレス０と一致するので、リモコン制御部１８によって赤外線信号の解読処理を行い、リモコン１０の表示部１９へアドレス４の照明器具１の調光率情報を表示する。
【００１９】
また、照明器具１のランプ２がリモコン１０の操作によって点灯させられた場合には、照明器具コントローラ３の記憶部１３内にはカウンタが設けられており、図３に示すように当初はランプ２の点灯時間がゼロ時間でカウンタ値は０にセットされているが、ランプ２が点灯されると、器具制御部１２の計時手段１２ｂがランプ２の点灯時間を計測し、点灯時間がある所定時間（図３では１０時間に設定）に達すると、器具制御部１２は記憶部１３内のカウンタ値を１として記憶部１３に記憶格納する。次にまた所定時間（ここでは１０時間）を計測すると、記憶部１３内に記憶格納されていたカウンタ値１をカウントアップしてカウンタ値２として記憶部１３に記憶格納する。このようにある所定時間を計時し、所定時間経過毎に記憶部１３のカウンタ値を増加していくように動作する。
【００２０】
ここで、リモコン１０から照明器具１の照明器具コントローラ３に対して照明器具１の動作情報としてランプ２の累積点灯時間を要求する赤外線信号がリモコン１０の赤外線信号送信部６から赤外線信号として送信された場合に、照明器具１の照明器具コントローラ３はリモコン１０からの赤外線信号を受信し、器具制御部１２で赤外線信号の解読処理を行い、記憶部１３に格納されているカウンタ値を読み出す。ここで図３のＡ点で示すように、カウンタ値が５であればランプ２の累積点灯時間は５０時間から６０時間の間であることが分かる。
そこで、器具制御部１２は累積点灯時間が略５０時間であるという情報を付与した赤外線信号を生成し、器具赤外線送信部１４を介して送信する。
次に、累積点灯時間が略５０時間であるという情報を付与した赤外線信号をリモコン１０の赤外線受信部１７で受信すると、リモコン制御部１８で赤外線信号の解読処理を行い、表示部１９に照明器具１の累積点灯時間は略５０時間である旨を表示する。
【００２１】
なお、ここでは点灯時間計時のためのある所定時間を１０時間としているが、この時間は特に決められたものではなく任意の時間で構わず、例えば１分毎にカウントアップするように計時すれば、より高精度に累積点灯時間を示すことができる。また、記憶部１３は不揮発性メモリ等で構成するため、照明器具１の電源を遮断しランプ２を消灯し、再度電源投入により点灯させるような場合においても、記憶部１３のカウンタ値は保持されるため、累積して点灯時間を計時することが可能である。
【００２２】
なお、上述の動作説明において、リモコン１０からアドレス４の照明器具１までの赤外線信号の通信順序をリモコン１０送信→アドレス１（送信、受信）→アドレス２（受信、送信）→アドレス３（受信、送信）→アドレス４（受信）と説明し、アドレス４からリモコン３まではその逆順で説明したが、これは赤外線通信の状態をわかりやすく説明するためで、赤外線の床面反射の条件や、照明器具設置状態で赤外線の通信に関与する器具は異なる。
また、設置されている照明器具の全数が中継の為の赤外線通信に関与するとは限らず、リモコン１０と対象照明器具のみの場合や、設置台数のうち数台が中継のために赤外線通信に関与する場合がある。
【００２３】
また、上述の動作説明では、特定のアドレスをリモコン３から指定する例を挙げたが、グループ等を指定してもよい。また、記憶部１３に記憶格納する動作情報は調光率だけでなく、ランプの点灯／消灯の情報や、照明器具自身又はランプの異常を示すような情報でも良く、この場合は容易にランプの状態や照明器具のメンテナンス情報を手元で確認することができる。
【００２４】
以上のようにリモコン１０により４つの照明器具１に対して調光制御を行っており、その調光制御の状態を照明器具状態監視装置２１が監視している。
以下、照明器具状態監視装置２１の動作について説明する。
照明器具状態監視装置２１の赤外線信号受信部２２では、リモコン１０から照明器具１の照明コントローラ３へ、又は照明コントローラ３から別の照明コントローラ３へ、或いは照明器具１の照明コントローラ３からリモコン１０へ送信される赤外線信号を受信している。
照明器具状態監視装置２１のＣＰＵ２３では赤外線信号受信部２２が受信した赤外線信号に基づいて各照明器具１のランプの点滅状態、調光状態である調光率等の調光情報から消費電力を演算する。
即ち、照明装置状態監視装置２１の記憶部２５には、図５に示すように各照明器具１の調光率と消費電力の関係を示す調光率−消費電力テーブルＴが記憶格納されており、また各照明器具１の照明コントローラ３の器具制御部１２は累積点灯時間の情報を付与した赤外線信号を生成し、器具赤外線送信部１４を介してリモコン１０へ送信している。
【００２５】
従って、ＣＰＵ２３では、例えば照明器具１について見ると、記憶部２５に格納記憶されている照明器具１の調光率と消費電力の関係を示す調光率−消費電力テーブルＴから調光率が９８％と分かると、その調光率における消費電力は９７Ｗであり、また照明器具１の照明器具コントローラ３の器具赤外線送信部１４からリモコン１０へ送信している累積点灯時間の情報とで消費電力量を演算することができることとなる。なお、照明器具１の点灯時間はリモコン１０からの点灯／消灯の調光制御情報に基づいても演算することができる。
【００２６】
また、ＣＰＵ２３が演算した照明器具１の消費電力量は、操作部２６で表示操作することによって表示部２４に表示される。従って、表示部２４に表示された照明器具の消費電力量を見ることにより、リアルタイムに消費電力量の監視をすることができる。
このような照明装置状態監視装置２１はリモコン１０又は照明器具１の照明器具コントローラ３と赤外線通信を行うので、照明器具の消費電力を監視するために照明装置状態監視装置２１を設置する場合には電気工事を不要とし、設置場所の制約もないことによりユーザに使い易いものとなっている。
さらに、表示部２４に表示された照明器具１の消費電力量は、操作部２６で記録出力操作すると、記録部出力部２９により記録出力される。即ち、記録出力部２９がプリンタであれば、照明器具１の消費電力量をプリントアウトすることができる。このとき、タイマ部３０は時刻を計時しているので、測定時刻のタイムスタンプを付加してプリントアウトすることもできる。
【００２７】
以上は、ＣＰＵ２３が照明器具１についての消費電力量を算出する例であるが、各照明器具にはアドレス番号がついているために、それぞれの照明器具を特定してそれについての消費電力量を演算することができる。
従って、操作部２６で単独、複数又は全ての照明器具について表示するように表示操作することにより、単独、複数又は全ての照明器具についての消費電力量を表示部２４に表示させることができ、必要に応じてこれらの時系列での消費電力量も表示させることができる。さらに、表示部２４に表示されたこれらの消費電力量は、操作部２６で記録出力操作すると、記録出力部２９により記録出力される。
【００２８】
また、表示部２４には照明器具１の消費電力量だけでなく、照明器具１の点滅状態や調光状態である調光率も表示させることができることは勿論であり、記録出力部２９に照明器具の点滅状態や調光状態も記録出力させることができる。
従って、照明器具の消費電力、点滅状態、調光状態である調光率を手元で確認できるため、照明器具の電力管理を容易に行うことができる。
また、記憶部２５に記憶させた時系列の照明器具の調光状態や消費電力の情報を記録出力部２９に記録出力させ、記録出力された情報に基づいて省エネ効果を検討したり、国際標準化機構の国際標準規格であるＩＳＯ１４００１等の情報収集に用いることができる。
【００２９】
さらに、記録出力部２９に記録出力させた照明器具の調光状態や消費電力の情報から、逆に電力カット、例えば調光率を１割下げる等の制御を行うために、操作部２６を操作して赤外線信号送信部２７から照明器具１の照明器具コントローラ３に例えば調光率を１割下げるという修正した調光制御情報を送信することもできる。
また、照明装置状態監視装置２１の外部入出力部２８は、照明器具１の照明器具コントローラ３より受けた情報や、記憶部２５に格納されている照明器具の調光状態や消費電力の情報を、直接は赤外線信号が届かない場所である外部の集中制御装置３１に有線で送ったりすることもできる。
【００３０】
このような複数の照明器具が部屋単位、又は階単位でリモコンでそれぞれ調光制御されている場合には、部屋単位、又は階単位の照明器具の調光状態や消費電力の情報を集中制御装置３１が得ることにより、集中制御装置３１は集中的に調光状態や消費電力を管理することができる。
さらに、外部入出力部２８は外部の人感センサ等の信号を集中制御装置３１を経由して受け取った場合に、その信号に基づいて照明器具１の照明器具コントローラ３に照明器具の点滅の信号を赤外線信号送信部２７から送信することにより、人の有無に応じて照明器具１を点灯／消灯させるというよりきめの細かい調光制御も可能となる。なお、これらの動作は操作部２６で操作してＣＰＵ２３に指示することにより行う。
また、外部入出力部２８は、照明器具コントローラ３から受信した情報を赤外線信号送信部２７より同一、又は他の照明器具コントローラ３に中継、伝達することもできる。
【００３１】
また、この実施の形態では、リモコン１０を親機とし、複数の照明器具１の照明器具コントローラ３を子機及び中継器とし、リモコン１０から照明器具１に対する調光制御情報を出すと、その調光制御情報が複数の照明器具１の照明器具コントローラ３で受信されるようにしているが、リモコン１０に代わる固定式の親機としてもよく、さらに複数の照明器具１の照明器具コントローラ３のうちの１つに照度センサ等を設けてそれを親機としてもよいことは勿論である。
また、照明装置状態監視装置２１の操作部２６にリモコン１０と同様の機能を持たせるようにすることもできる。
【００３２】
【発明の効果】
以上のように本発明によれば、複数の照明器具の子機に相当する照明器具コントローラが親機から受信した赤外線信号の調光制御情報に基づいてランプに対して調光制御を行い、必要に応じて親機から受信した赤外線信号を送信するようにして複数の照明器具が調光制御されている場合に、照明器具状態監視装置の監視制御手段は、その赤外線信号受信部が受信した親機又は子機からの赤外線信号の調光制御情報に基づいて照明器具の調光情報を演算して求めるようにしたので、その照明器具の調光情報を監視することが可能となるという効果がある。
また、照明装置状態監視装置は親機又は照明器具の子機と赤外線通信を行うので、照明器具の消費電力を監視するために照明装置状態監視装置を設置する場合には電気工事を不要とし、設置場所の制約もないことによりユーザに使い易いものとなるという効果がある。

[0012]
In addition, the storage unit 25 of the lighting device state monitoring device 21 stores and stores a dimming rate-power consumption table T indicating the relationship between the dimming rate and the power consumption of the lighting fixture 1 as shown in FIG.
Note that the infrared signal receiving section 22 is formed of a circuit including an infrared receiving element, the CPU 23 is formed of a personal computer, the display section 24 is a CRT or the like, and the storage section 25 is formed of a storage element / medium such as a RAM or HDD. The operation unit 26 is, for example, a keyboard or the like, the infrared signal transmission unit 27 is configured by a circuit including an infrared transmission element, the external input / output unit 28 is configured by RS-232C, Ethernet (registered trademark), or the like. Reference numeral 29 denotes a recorder or the like such as a printer or pen recorder, and the timer unit 30 is a clock for measuring time. Further, the central control device 31 centrally manages and controls the lighting equipment of the room, the floor or the whole building.
[0013]
Next, the operation of the lighting device state monitoring system according to the embodiment of the present invention will be described.
First, dimming control performed on, for example, four lighting devices 1 using the remote controller 10 will be described.
Here, a case will be described in which the lighting of the four lighting devices 1 is controlled by the remote controller 10 at a predetermined dimming rate, and thereafter the dimming rates are changed.
For example, when the infrared transmission unit 16 of the remote controller 10 transmits, for example, a command of light output UP, which is dimming control information, to the lighting fixture controller 3 of the lighting fixture 1 of the specific address 4 by an infrared signal, the transmission is performed. The address information of the lighting equipment to be further UP is added to the infrared signal. At this time, it is assumed that the infrared signal transmitted from the remote controller 10 is transmitted not to the lighting fixture controller 3 of the lighting fixture 1 of the address 4 but to the lighting fixture controller 3 of the lighting fixture 1 of the address 1.
Here, the luminaire controller 3 of the luminaire 1 at the address 1 determines in the luminaire controller 12 that the received infrared signal is not a command for itself (address 1), and performs control to increase the light output of the lamp. Instead, an infrared signal having the same content as the received infrared signal is transmitted from the appliance infrared transmitting unit 14.
[0014]
Next, the infrared signal transmitted from the lighting equipment controller 3 of the lighting equipment 1 of the address 1 is received by the lighting equipment controller 3 of the lighting equipment 1 of the address 2 directly or by reflection on the floor. The luminaire controller 3 of the luminaire 1 of the address 2 is not a command for itself like the luminaire controller 3 of the luminaire 1 of the address 1 described above. The data is transmitted from the infrared transmitting unit 14. Similarly, the infrared signal transmitted from the address 2 is received by the luminaire 1 at the address 3. However, since the instruction is not directed to itself, the infrared signal having the same content as the received infrared signal is transmitted to the luminaire. Transmitted from the unit 14.
[0015]
Next, when the lighting equipment controller 3 of the lighting equipment 1 of the address 4 receives the infrared signal transmitted by the lighting equipment controller 3 of the lighting equipment 1 of the address 3, the received infrared signal is designated for itself (address 4). Therefore, the received infrared signal is decoded by the fixture control unit 12, and the lighting circuit unit 11 is controlled so as to increase the light output of the lighting fixture 1 at the address 4. At this time, the dimming rate indicating the degree of the light output of the lamp 2 that is being output is detected by the operation detection unit 12a, and is output to the storage unit 13 of the lighting fixture controller 3 of the lighting fixture 1 at the address 4. A dimming rate indicating the degree of light output of the lamp is stored and stored.
[0016]
Next, the remote controller 10 sends the operation information of the luminaire 1 at the address 4, for example, an infrared signal requesting the dimming rate of the currently lit lamp 2 to the infrared signal transmitter 16 of the remote controller 10. When the infrared signal transmitted from the remote controller 10 is received by the lighting equipment controller 3 of the lighting equipment 1 at the address 1, the equipment control unit 12 determines that the request is not a request for itself (address 1). Judgment is made, and the appliance infrared transmitter 14 transmits an infrared signal having the same content as the infrared signal received by the appliance infrared receiver 15. Here, assuming that the lighting device controller 3 of the lighting device 1 of the address 2 receives the infrared signal, the infrared signal having the same content as the received infrared signal is transmitted in the same manner as the case where the lighting device 1 of the address 1 receives the infrared signal. . The same applies to the case where the device at address 3 receives the data.
[0017]
When the lighting device controller 3 of the lighting device 1 of the address 4 receives this infrared signal, it is a request for itself (address 4), so the lighting device controller 3 of the lighting device 1 of the address 4 is stored in the storage unit 13. The stored dimming rate is read by the appliance control unit 12, and an infrared signal to which the address information of the remote controller 10 as address 0 and the dimming rate information are added is transmitted from the appliance infrared transmitting unit 14 to the remote controller 10.
When the infrared signal to which the dimming rate information is added is transmitted from the lighting equipment controller 3 of the lighting equipment 1 of the address 4 and received by the lighting equipment controller 3 of the lighting equipment 1 of the address 3, the infrared signal itself (address 3). The appliance control unit 12 determines that the received signal is not a command signal to the remote controller 10 but a signal to the remote controller 10, and transmits an infrared signal having the same content as the received infrared signal. In the same manner, even when the lighting equipment at address 2 and the lighting equipment at address 1 receive the signal, the signal is not a command signal for itself, so that an infrared signal similar to the received infrared signal is transmitted.
[0018]
Then, the remote controller 10 receives the infrared signal added with the dimming rate information transmitted by the lighting apparatus controller 3 of the lighting apparatus 1 of the address 4 by the infrared receiving unit 17 or the address 4 via the lighting apparatus of another address. When the infrared light signal with the address information and the dimming rate information transmitted by the lighting equipment controller 3 of the lighting equipment 1 is received, the address information coincides with its own address 0. The signal is decoded, and the dimming rate information of the luminaire 1 at the address 4 is displayed on the display unit 19 of the remote controller 10.
[0019]
When the lamp 2 of the lighting fixture 1 is turned on by the operation of the remote controller 10, a counter is provided in the storage unit 13 of the lighting fixture controller 3, and as shown in FIG. The lighting time of is zero time and the counter value is set to 0, but when the lamp 2 is turned on, the timer 12b of the appliance control unit 12 measures the lighting time of the lamp 2, and the lighting time is a predetermined time. When it reaches (set to 10 hours in FIG. 3), the appliance control unit 12 stores the counter value in the storage unit 13 as 1 in the storage unit 13. Next, when a predetermined time (here, 10 hours) is measured again, the counter value 1 stored and stored in the storage unit 13 is counted up and stored in the storage unit 13 as the counter value 2. As described above, the operation is performed such that the predetermined time is counted, and the counter value of the storage unit 13 is increased every time the predetermined time elapses.
[0020]
Here, an infrared signal requesting the cumulative lighting time of the lamp 2 as operation information of the lighting device 1 from the remote control 10 to the lighting device controller 3 of the lighting device 1 is transmitted as an infrared signal from the infrared signal transmitting unit 6 of the remote control 10. In this case, the lighting fixture controller 3 of the lighting fixture 1 receives the infrared signal from the remote controller 10, performs a decoding process of the infrared signal in the fixture control unit 12, and reads the counter value stored in the storage unit 13. Here, as shown by the point A in FIG. 3, if the counter value is 5, it is understood that the cumulative lighting time of the lamp 2 is between 50 hours and 60 hours.
Therefore, the appliance control unit 12 generates an infrared signal to which information that the cumulative lighting time is approximately 50 hours is added, and transmits the infrared signal via the appliance infrared transmission unit 14.
Next, when an infrared signal provided with information indicating that the cumulative lighting time is approximately 50 hours is received by the infrared receiver 17 of the remote controller 10, the remote controller controller 18 performs decoding processing of the infrared signal, and displays the lighting equipment on the display unit 19. 1 indicates that the cumulative lighting time is approximately 50 hours.
[0021]
Note that, here, a predetermined time for lighting time measurement is set to 10 hours, but this time is not particularly determined and may be an arbitrary time. For example, if the time is counted up every minute, Thus, the accumulated lighting time can be indicated with higher accuracy. Further, since the storage unit 13 is configured by a nonvolatile memory or the like, the counter value of the storage unit 13 is retained even in a case where the power of the lighting apparatus 1 is turned off, the lamp 2 is turned off, and the power is turned on again by turning on the power. Therefore, the lighting time can be counted cumulatively.
[0022]
In the above description of the operation, the communication order of the infrared signal from the remote controller 10 to the lighting fixture 1 at the address 4 is changed from the remote controller 10 transmission → address 1 (transmission, reception) → address 2 (reception, transmission) → address 3 (reception, The description was made in the order of (transmission) → address 4 (reception), and the address 4 to the remote controller 3 were described in reverse order, but this is for the purpose of explaining the state of the infrared communication in an easily understandable manner. The devices involved in infrared communication in the device installation state are different.
Also, not all of the installed lighting fixtures are involved in infrared communication for relaying, and only the remote control 10 and target lighting fixtures are involved, or some of the installed units are involved in infrared communication for relaying. May be.
[0023]
In the above description of the operation, an example in which a specific address is specified from the remote controller 3 has been described, but a group or the like may be specified. The operation information stored and stored in the storage unit 13 may be not only the dimming rate but also information on turning on / off the lamp or information indicating abnormality of the lighting fixture itself or the lamp. The status and maintenance information of the lighting equipment can be checked at hand.
[0024]
As described above, dimming control is performed on the four lighting fixtures 1 by the remote controller 10, and the lighting fixture state monitoring device 21 monitors the state of the dimming control.
Hereinafter, the operation of the lighting fixture state monitoring device 21 will be described.
In the infrared signal receiving unit 22 of the lighting fixture condition monitoring device 21, the remote controller 10 sends the light to the lighting controller 3 of the lighting fixture 1, the lighting controller 3 sends it to another lighting controller 3, or the lighting controller 1 of the lighting fixture 1 sends the remote control 10 to the remote controller 10. Receiving the transmitted infrared signal.
The CPU 23 of the lighting fixture condition monitoring device 21 calculates the power consumption from the dimming information such as the blinking state of the lamp of each lighting fixture 1 and the dimming rate, which is a dimming state, based on the infrared signal received by the infrared signal receiving unit 22. I do.
That is, the storage unit 25 of the lighting device state monitoring device 21 stores and stores the dimming rate-power consumption table T indicating the relationship between the dimming rate and the power consumption of each lighting fixture 1 as shown in FIG. In addition, the fixture control unit 12 of the lighting controller 3 of each lighting fixture 1 generates an infrared signal to which information on the cumulative lighting time has been added, and transmits the signal to the remote controller 10 via the fixture infrared transmission unit 14.
[0025]
Therefore, in the CPU 23, for example, regarding the lighting fixture 1, the dimming rate is 98 based on the dimming rate-power consumption table T indicating the relationship between the dimming rate and the power consumption of the lighting fixture 1 stored and stored in the storage unit 25. %, The power consumption at the dimming rate is 97 W, and the power consumption amount is calculated based on the cumulative lighting time information transmitted from the appliance infrared transmitter 14 of the lighting fixture controller 3 of the lighting fixture 1 to the remote controller 10. Can be calculated. In addition, the lighting time of the lighting fixture 1 can also be calculated based on dimming control information for turning on / off the light from the remote controller 10.
[0026]
The power consumption of the lighting device 1 calculated by the CPU 23 is displayed on the display unit 24 by performing a display operation on the operation unit 26. Therefore, the power consumption can be monitored in real time by looking at the power consumption of the lighting fixture displayed on the display unit 24.
Since such a lighting device condition monitoring device 21 performs infrared communication with the remote controller 10 or the lighting device controller 3 of the lighting device 1, when the lighting device condition monitoring device 21 is installed to monitor the power consumption of the lighting device, It eliminates the need for electrical work and has no restrictions on the installation location, making it easy for the user to use.
Further, the power consumption of the lighting fixture 1 displayed on the display unit 24 is recorded and output by the recording unit output unit 29 when the recording and output operation is performed by the operation unit 26. That is, if the recording output unit 29 is a printer, the power consumption of the lighting fixture 1 can be printed out. At this time, since the timer unit 30 measures the time, the time stamp of the measurement time can be added to print out.
[0027]
The above is an example in which the CPU 23 calculates the power consumption of the lighting fixture 1. Since each lighting fixture has an address number, the lighting fixture is specified and the power consumption of the lighting fixture is calculated. can do.
Therefore, by performing a display operation on the operation unit 26 so as to display a single, a plurality, or all of the lighting devices, the power consumption of the single, a plurality, or all the lighting devices can be displayed on the display unit 24. , The power consumption in these time series can also be displayed. Further, these power consumption amounts displayed on the display unit 24 are recorded and output by the recording output unit 29 when a recording output operation is performed by the operation unit 26.
[0028]
The display unit 24 can display not only the power consumption of the lighting apparatus 1 but also the dimming rate of the lighting apparatus 1 in a blinking state or a dimming state. The blinking state and dimming state of the device can be recorded and output.
Accordingly, the power consumption of the lighting fixture, the dimming rate in the blinking state, and the dimming state can be checked at hand, so that the power management of the lighting fixture can be easily performed.
Further, the information on the dimming state and the power consumption of the time-series lighting fixtures stored in the storage unit 25 is recorded and output to the recording output unit 29, and the energy saving effect is examined based on the recorded and output information. It can be used to collect information such as ISO14001, which is an international standard of the Organization.
[0029]
Further, the user operates the operation unit 26 to perform control such as power cut, for example, decreasing the dimming rate by 10%, based on the information on the dimming state and the power consumption of the lighting apparatus recorded and output to the recording output unit 29. Then, it is also possible to transmit the corrected dimming control information to lower the dimming rate by 10%, for example, from the infrared signal transmitting unit 27 to the lighting fixture controller 3 of the lighting fixture 1.
Further, the external input / output unit 28 of the lighting device state monitoring device 21 transmits the information received from the lighting device controller 3 of the lighting device 1 and the information on the dimming state and the power consumption of the lighting device stored in the storage unit 25. Alternatively, the signal can be sent to the external central control device 31 which is a place where the infrared signal does not reach directly by wire.
[0030]
In the case where such a plurality of lighting fixtures are individually controlled by a remote controller in units of rooms or floors, the information on the dimming state and power consumption of the lighting fixtures in units of rooms or floors is centrally controlled. As a result, the centralized control device 31 can centrally manage the dimming state and the power consumption.
Further, when the external input / output unit 28 receives a signal from an external motion sensor or the like via the central control device 31, the external input / output unit 28 sends a signal to the lighting fixture controller 3 of the lighting fixture 1 to blink the lighting fixture based on the signal. Is transmitted from the infrared signal transmitting unit 27, so that finer dimming control of turning on / off the lighting apparatus 1 according to the presence or absence of a person is also possible. These operations are performed by operating the operation unit 26 and instructing the CPU 23.
In addition, the external input / output unit 28 can relay and transmit the information received from the lighting fixture controller 3 to the same or another lighting fixture controller 3 from the infrared signal transmitting unit 27.
[0031]
Also, in this embodiment, when the remote controller 10 is a master unit, the lighting controller 3 of the plurality of lighting fixtures 1 is a slave unit and a repeater, and when the remote controller 10 issues dimming control information for the lighting fixture 1, the lighting controller 1 Although the light control information is received by the lighting fixture controller 3 of the plurality of lighting fixtures 1, the light control information may be a fixed master unit instead of the remote controller 10. Of course, an illuminance sensor or the like may be provided in one of them, and that may be used as a master unit.
Further, the operation unit 26 of the lighting device state monitoring device 21 may have the same function as the remote controller 10.
[0032]
【The invention's effect】
As described above, according to the present invention, the lighting fixture controller corresponding to the slave units of the plurality of lighting fixtures performs the dimming control on the lamp based on the dimming control information of the infrared signal received from the master unit, and In the case where a plurality of lighting fixtures are subjected to dimming control by transmitting an infrared signal received from the master unit according to the condition, the monitoring control means of the lighting fixture state monitoring device transmits the infrared signal received by the infrared signal receiving unit. Since the dimming information of the lighting fixture is calculated and obtained based on the dimming control information of the infrared signal from the handset or the slave unit, it is possible to monitor the dimming information of the lighting fixture. is there.
Also, since the lighting device condition monitoring device performs infrared communication with the parent device or the slave device of the lighting device, when installing the lighting device condition monitoring device to monitor the power consumption of the lighting device, electrical work is unnecessary, Since there is no restriction on the installation place, there is an effect that it becomes easy for the user to use.
