【０００１】
【発明の属する技術分野】
この発明は、照明装置に関するものであり、特に複数の照明器具にそれぞれ赤外線の送受信部を備え、赤外線による照明器具間の通信を行い照明制御する照明装置に関するものである。
【０００２】
【従来の技術】
複数の照明器具を連動させて照明制御を行う照明装置としては、従来から様々な照明装置が提案されている。
図４は第１の従来の照明装置を示す構成図である。この従来の照明装置は三菱電機照明製で、「省エネ照明用自動調光システム」カタログに記載のものである。
図４において、１３は照明制御操作を行うリモコン、１４はリモコン１３から発信された照明制御の赤外線信号、１８はリモコン１３からの受信した赤外線信号１４を照明制御の電気信号に変換して出力する制御回路、１９ａ、１９ｂ、１９ｃはランプ２が装着された照明器具を示す。各照明器具１９ａ、１９ｂ、１９ｃは制御装置１８と専用の制御信号線２０で接続されている。また、図４では３台の照明器具で構成する照明装置を示しているが、実際の照明装置ではそれ以上の台数の照明器具で構成される場合もある。
【０００３】
次に、第１の従来の照明装置の動作について説明する。
制御装置１８はリモコン１３からの照明制御の赤外線信号１４を受信すると、受信した赤外線信号を照明制御の電気信号に変換して、制御信号線２０を介して各照明器具１９ａ、１９ｂ、１９ｃに電気信号を伝達する。
この従来の照明装置では、リモコン１３から照明器具１９ａ、１９ｂ、１９ｃのランプ２の明るさを示す調光度である照明制御の赤外線信号１４を制御装置１８に送信する。
【０００４】
その赤外線信号１４を受信した制御装置１８では、受信した赤外線信号に示される調光度になるように電気信号に変換して制御信号を生成し、制御信号線２０を用いて照明器具１９ａ、１９ｂ、１９ｃに配信する。配信された制御信号を受けた各照明器具１９ａ、１９ｂ、１９ｃは制御装置１８から送られた調光度でランプ２を点灯するよう動作する。
従って、第１の従来の照明装置では、リモコン１３から各照明器具１９ａ、１９ｂ、１９ｃの明るさをコントロールすることが可能になる。
【０００５】
図５は第２の従来の照明装置を示す構成図、図６は同照明装置の照明器具の構成を示すブロック図、図７は同照明装置の照明器具の構成を示す外観図である。図５において、１２ａ、１２ｂ、１２ｃは照明器具、１３は照明制御操作を行うリモコン、１４はリモコン１３から発信された照明制御の赤外線信号、１５は照明器具１２ａ、１２ｂ、１２ｃより発信された赤外線信号、１６は赤外線信号１５が床面に反射した後の反射赤外線信号である。
また、図５では３台の照明器具で構成する照明装置を示しているが、実際の照明装置ではそれ以上の台数の照明器具で構成される場合もある。
【０００６】
図６は図５で説明した各照明器具１２の構成を示す。照明器具１２はランプ２が装着され、点灯装置２１が内蔵されている。その点灯装置２１は赤外線信号を送信する赤外線送信部８と、赤外線信号を受信する赤外線受信部９と、赤外線受信部９からの赤外線信号を受信し、赤外線送信部８に照明制御指令を出力し、調光指令を出力する制御部４と、制御部４からの調光指令によりランプ２を調光制御するインバータ部５とで構成されている。
【０００７】
図７は図５及び図６で説明した照明器具１２の外観を示す。照明器具１２にはランプ２が装着され、ランプ２の光を効率よく照射するための反射板２２が取り付けられている。点灯装置２１は反射板２２の内側に配置され、点灯装置２１内の赤外線送信部８と赤外線受信部９は反射板２２に設けられた孔から臨む構造になるように配置されている。
【０００８】
次に、第２の従来の照明装置の動作について図５を用いて説明する。
照明器具１２ａはリモコン１３からの照明制御の赤外線信号１４を赤外線受信部９で受信すると、制御部４では赤外線受信部９で受信した赤外線信号を照明制御の電気信号に変換し、インバータ部５に調光指令を出力し、インバータ部５はランプ２を調光制御する。
【０００９】
それと同時に、制御部４は赤外線受信部９が受信した先の赤外線信号１４を他の照明器具１２ｂ、１２ｃへ送信するため、照明制御指令を赤外線送信部８に送り、赤外線送信部８は赤外線受信部９が受信した先の赤外線信号１４と同じ内容の赤外線信号１５を赤外線送信部８から送信する。
このように、第２の従来の照明装置では、リモコン１３からの赤外線信号を照明器具間の赤外線通信によりワイヤレスで配信し、各照明器具１２ａ、１２ｂ、１２ｃの明るさをコントロールすることを可能にしている。
【００１０】
【発明が解決しようとする課題】
第１の従来の照明装置では、リモコン１３からの赤外線信号を１４を受信した制御装置１８が制御信号線２０を介して複数の照明器具１９ａ、１９ｂ、１９ｃの調光を制御するようにしているから、制御装置１８と照明器具１９を制御信号線２０で接続する必要があり、施工にコストがかかるという問題点があった。
また、既存の照明器具を変更して、第１の従来例のような照明装置を構築するには手間がかかり不向きであるという問題もあった。
【００１１】
また、第２の従来の照明装置では、照明器具１２に赤外線送信部８と赤外線受信部９を備え、照明器具１２間を赤外線によるワイヤレスで通信して複数の照明器具１２の調光を制御するようにしているので、先にあげた第１の従来の照明装置の問題点を解消することができる。
しかしながら、光である赤外線を媒体として床面の反射等を利用して照明器具間の通信を実現しているため、照明器具１２の設置場所に赤外線の届く範囲という制約が生じ、また床面に配置される什器等の赤外線遮蔽物の存在で照明器具１２間の赤外線通信ができない場合があるという問題点があった。
【００１２】
この発明は上記のような問題点を解決するためになされたもので、各照明器具を赤外線によるワイヤレスで結ぶことで、照明器具間の配線作業が不要となり、しかも赤外線遮蔽物があっても確実に赤外線通信できる照明装置を提供することを目的とする。
【００１３】
【課題を解決するための手段】
本発明に係る照明装置は、リモコン又は他の照明器具からの照明制御の赤外線信号を受けてランプの光出力を増減させるように動作すると共に赤外線信号を外部に送信する照明装置であって、ランプを点灯・調光制御する照明器具と、赤外線信号を受信して照明制御信号に変換して前記照明器具に出力する送受信ユニットと、前記送受信ユニットと前記照明器具を接続する信号線とを備え、前記送受信ユニットは、赤外線信号を受信する赤外線受信部と、受信した赤外線信号と同じ内容の赤外線信号を他の照明器具に送るための照明制御指令を前記照明器具から受信して、この照明制御指令に基づき赤外線信号を送信する赤外線送信部とを備え、前記照明器具は、受信した赤外線信号を他の照明器具に配信するため、受信した赤外線信号と同じ内容の赤外線信号を送るための照明制御指令を前記信号線を介して前記送受信ユニットに送る制御部を備えてなるものである。

【００１５】
【発明の実施の形態】
実施の形態１．
図１はこの発明の実施の形態１の照明装置を構成する照明器具を示すブロック図、図２は同照明装置を構成する照明器具を示す外観図、図３はこの発明の実施の形態１と第２の従来の照明装置の使用状態をそれぞれ模式的に表した模式図である。
図１において、１はランプ２が装着される照明器具、３は照明器具１に内蔵される点灯装置である。点灯装置３は後述する赤外線受信部で受信した照明制御の赤外線信号から制御信号を生成する制御部４と、制御部４からの調光指令によりランプ２を点灯させ、光出力を増減させるよう動作するインバータ部５と、後述する送受信ユニットと信号の授受を行う第２のインターフェイス部（以下、第２のＩ／Ｆ部と略す）６とを備えて構成されている。
【００１６】
７は照明装置１と信号のやりとりを行う送受信ユニットである。この送受信ユニット７は、照明制御の赤外線信号を送信する赤外線送信部８と、赤外線信号を受信する赤外線受信部９と、照明器具１の第２のＩ／Ｆ部６を介して信号の授受を行う第１のインターフェイス部（以下、第１のＩ／Ｆ部と略す）１０とで構成されている。この送受信ユニット７の第１のＩ／Ｆ部１０と照明器具１の第２のＩ／Ｆ部６とは信号線１１で接続されている。
【００１７】
図２は図１で説明した照明器具１と送受信ユニット７の外観を示す。その照明器具１にはランプ２が装着され、ランプ２の光を効率よく照射するための反射板２２が取り付けられている。この反射板２２の内側に点灯装置３が内蔵された配置になっている。
図３の（ａ）において、１２は第２の従来例で示した照明器具と同様の構成の照明器具である。従って、照明器具１２はランプ２と点灯装置２１とからなり、点灯装置２１は赤外線送信部８と赤外線受信部９と制御部４とインバータ部５とを有している（図示省略）。
１３は照明制御操作を行うリモコン、１４はリモコン１３から出力された照明制御の赤外線信号、１５は照明器具１２から送信された赤外線信号、１６は赤外線信号１５が床面で反射した反射赤外線信号１６、１７は床面に配置された赤外線遮蔽物となる什器である。
【００１８】
次に、この発明の実施の形態１の照明装置の動作について図３に基づいて説明する。
照明器具１２は第２の従来例で説明したの同様に、ランプの調光度をあらわすリモコン１３からの照明制御の赤外線信号１４を受信すると、受信した赤外線信号を照明制御の電気信号に変換し、受信した内容に基づきランプ２を点灯・調光制御、即ちランプの２の光出力を制御すると共に受信した赤外線信号１４と同じ内容の赤外線信号１５を送信する。
この照明器具１２から送信された赤外線信号１５は直接又は床面などの反射による反射赤外線信号１６によって送受信ユニット７で受信される。
【００１９】
反射赤外線信号１６を受信した送受信ユニット７の赤外線受信部９は赤外線信号を照明制御の電気信号に変換し、その電気信号は第１のＩ／Ｆ部１０から信号線１１を経由して照明器具１内部の第２のＩ／Ｆ部６に伝達され、第２のＩ／Ｆ部６からの照明制御の電気信号を受けた制御部４は調光指令を生成し、インバータ部５は制御部４からの調光指令に基づきランプ２の光出力を制御する。
【００２０】
それと同時に、制御部４は受信した赤外線信号を他の照明器具（図示せず）に配信するため、受信した赤外線信号と同じ内容の赤外線信号を送るための照明制御指令を第２のＩ／Ｆ部６より信号線１１を介して送受信ユニット７の第１のＩ／Ｆ部１０に送り、送受信ユニット７ではその赤外線送信部８が照明制御指令に基づいて赤外線信号を送信する。
【００２１】
次に、照明器具１２、照明器具１と送受信ユニット７及び赤外線遮蔽物である什器１７の位置関係について説明する。
図３の（ａ）で示した照明器具１２と照明器具１の間には例えばパーティション等の什器１７が配置されていた場合を想定する。
図３の（ｂ）では、図３の（ａ）に示す照明器具１の位置に、照明器具１２と同様の照明器具１２を配置し、２台の照明器具１２で照明装置を構成した場合を示す。即ち、第２の従来例に示した２台の照明器具１２の構成とし、これら照明器具１２間に什器１７が配置されているとする。
【００２２】
そうすると、図３の（ｂ）に示すように、反射赤外線信号１６は什器１７で遮断されてしまうために照明器具１２間での赤外線通信は行えず、リモコン１３の操作による照明器具１２のコントロールは不可能になる。
ところが、図３の（ａ）に示すように照明器具１を配置し、送受信ユニット７を反射赤外線１６が什器１７に遮断されることなく受信可能な位置に配置することにより、照明器具１２と照明器具１間の赤外線による信号の授受が可能となり、リモコン１３の操作による照明器具１のコントロールができるようになる。
【００２３】
以上のように、この発明の実施の形態１の照明装置では、照明器具１は送受信ユニット７との接続を送受信ユニット７の第１Ｉ／Ｆ部１０と照明器具１の第２のＩ／Ｆ部６を信号線１１で接続し、送受信ユニット７は赤外線遮蔽物である什器１７を回避した任意の位置に照明器具１から分離して設置しているので、照明器具１と照明器具１２とを赤外線によるワイヤレスで結ぶことにより、照明器具１、１２間の配線作業が不要となり、しかも赤外線遮蔽物があっても確実に赤外線通信で照明器具１をコントロールすることができる。
【００２４】
また、照明器具１の第２のＩ／Ｆ部６に対して複数の送受信ユニット７を信号線１１を介して接続することにより、他の赤外線遮蔽物である什器等で赤外線が遮断されるような他の照明器具１への赤外線信号の伝達も可能となり、一層赤外線通信の範囲の拡大と確実性を向上させることができる。
【００２５】
【発明の効果】
本発明は以上説明したように、ランプを点灯・調光制御する照明器具と、赤外線信号を受信して照明制御信号に変換して前記照明器具に出力する送受信ユニットと、前記送受信ユニットと前記照明器具を接続する信号線とを備え、前記送受信ユニットは、赤外線信号を受信する赤外線受信部と、受信した赤外線信号と同じ内容の赤外線信号を他の照明器具に送るための照明制御指令を前記照明器具から受信して、この照明制御指令に基づき赤外線信号を送信する赤外線送信部とを備え、前記照明器具は、受信した赤外線信号を他の照明器具に配信するため、受信した赤外線信号と同じ内容の赤外線信号を送るための照明制御指令を前記信号線を介して前記送受信ユニットに送る制御部を備えてなるから、送受信ユニットを赤外線遮蔽物を回避した任意の位置に照明器具から分離して設置できるため、他の照明器具との配線作業が不要となり、しかも赤外線遮蔽物があっても確実に赤外線通信で照明器具をコントロールすることができるという効果がある。

Each lighting fixture 19a, 19b, 19c is connected to the control device 18 by a dedicated control signal line 20. Moreover, although the illuminating device comprised by three lighting fixtures is shown in FIG. 4, in an actual illuminating device, it may be comprised by the number of lighting fixtures more than that.

[0004]
The control device 18 that has received the infrared signal 14 generates a control signal by converting it into an electric signal so as to have a dimming degree indicated by the received infrared signal, and uses the control signal line 20 to illuminate 19a, 19b, Delivered to 19c. Each of the lighting fixtures 19 a, 19 b, 19 c that has received the distributed control signal operates to turn on the lamp 2 with the dimming degree sent from the control device 18.
Therefore, in the first conventional lighting device, it is possible to control the brightness of each lighting fixture 19a, 19b, 19c from the remote controller 13.

Thus, the above-mentioned problems of the first conventional lighting device can be solved.
However, since the communication between the lighting fixtures is realized by using the reflection of the floor surface using infrared light as a medium, the restriction of the range where the infrared rays reach the installation location of the lighting fixture 12 occurs.
