Description

本発明は、赤外線や特定小電力無線通信方式を用いた照明装置の無線式調光制御システムに関する。   The present invention relates to a wireless dimming control system for a lighting device using infrared rays or a specific low power wireless communication system.

従来から、遠隔操作装置を操作して照明装置の明るさを制御する無線式調光制御システムが実用化されている（特許文献１参照）。従来の無線式調光制御システムについて、図４を参照しつつ説明する。照明装置の調光レベルは、レベル１からレベル６までの６段階に調光可能であるとする。調光レベルがレベル１に設定されており、調光レベルを高くしようとする場合、ユーザは、遠隔操作装置に設けられている調光アップボタン（例えば、△ボタン）を操作する。遠隔操作装置は、ユーザが調光アップボタンを連続して押し続けている間、一定の間隔で所定の調光信号（調光アップ信号）を出力する。あるいは、ユーザが調光アップボタンを押している時間が所定の時間よりも短い場合は、ユーザが一度調光アップボタンを操作するたびに、１つずつ所定の調光信号を出力する。   Conventionally, a wireless dimming control system that operates a remote control device to control the brightness of a lighting device has been put into practical use (see Patent Document 1). A conventional wireless dimming control system will be described with reference to FIG. It is assumed that dimming levels of the lighting device can be dimmed in six levels from level 1 to level 6. When the dimming level is set to level 1 and the user wants to increase the dimming level, the user operates a dimming up button (for example, a Δ button) provided in the remote control device. The remote control device outputs a predetermined dimming signal (dimming up signal) at regular intervals while the user continues to press the dimming up button. Alternatively, when the time during which the user presses the dimming up button is shorter than the predetermined time, a predetermined dimming signal is output one by one each time the user operates the dimming up button.

照明装置では、受信部が遠隔操作装置からの調光アップ信号を受信するたびに、制御部は調光レベルを１段階ずつ高くする。ユーザは、自分の好みの調光レベル（明るさ）に到達した時点で、調光アップボタンの操作を停止する。照明装置の制御部は、遠隔操作装置からの新たな調光信号を受信するまで、そのときの調光レベルを記憶し、維持する。調光レベルを低くしようとする場合は、遠隔操作装置に設けられている調光ダウンボタン（例えば、▽ボタン）を操作すればよく、遠隔操作装置及び照明装置における動作は同様である。   In the illumination device, the control unit increases the dimming level by one step each time the receiving unit receives the dimming up signal from the remote control device. The user stops the operation of the dimming up button when the user's favorite dimming level (brightness) is reached. The control unit of the lighting device stores and maintains the light control level at that time until a new light control signal is received from the remote control device. In order to lower the dimming level, a dimming down button (for example, the ▽ button) provided in the remote operation device may be operated, and the operations in the remote operation device and the lighting device are the same.

従来の無線式調光制御システムでは、一般的に赤外線を用いて所定の調光信号を送信しており、１つの調光信号を送信する際、一定時間赤外線ＬＥＤが点灯し続けている。そして、１階の調光動作の際に送信される調光信号の数が多いため、ＬＥＤによる消費電力が大きく、遠隔操作装置の電池の寿命が短いという問題を有していた。   In a conventional wireless dimming control system, a predetermined dimming signal is generally transmitted using infrared rays, and when one dimming signal is transmitted, the infrared LED is continuously lit for a certain period of time. Since the number of dimming signals transmitted during the dimming operation on the first floor is large, there is a problem that power consumption by the LEDs is large and the battery life of the remote control device is short.

また、赤外線を用いた無線式調光制御システムでは、遠隔操作装置のＬＥＤ発光部と照明装置の受信部との間に障害物が存在すると、調光信号が正しく送受信されないという問題点を有していた。そのため、近年、特定小電力無線通信方式の規格（ＳＴＤ−Ｔ６７など）を用いた電波による無線式調光制御システムも提案されている。ところが、例えばＳＴＤ−Ｔ６７によれば、信号送信時間は５秒以内であり、その後必ず２秒間信号送信してはならないという規定が存在するため、調光動作を５秒以内に終了させる必要がある。ところが、ユーザによって、遠隔操作装置の調光アップボタン又は調光ダウンボタンの操作は様々であり、調光動作を５秒以内に終了させられない場合もありうる。
特開平５−７６０６４号公報 In addition, the wireless dimming control system using infrared rays has a problem that the dimming signal is not transmitted and received correctly if an obstacle exists between the LED light emitting unit of the remote control device and the receiving unit of the lighting device. It was. Therefore, in recent years, a wireless dimming control system using radio waves using a standard (STD-T67 or the like) of a specific low power wireless communication system has been proposed. However, according to STD-T67, for example, there is a regulation that the signal transmission time is within 5 seconds, and then signal transmission must not be performed for 2 seconds, so the dimming operation needs to be completed within 5 seconds. . However, the operation of the dimming up button or dimming down button of the remote control device varies depending on the user, and the dimming operation may not be completed within 5 seconds.
JP-A-5-76064

本発明は、上記従来例の問題を解決するためになされたものであり、遠隔操作装置の省電力化による電池寿命の延長及び調光信号の送受信に特定小電力無線通信方式の規格（ＳＴＤ−Ｔ６７など）の使用を可能にする無線式調光制御システムを提供することを目的とする。   The present invention has been made in order to solve the above-described problems of the conventional example. The standard (STD-) of a specific low-power wireless communication system is used for extending battery life and transmitting / receiving dimming signals by reducing power consumption of a remote control device. An object of the present invention is to provide a wireless dimming control system that enables use of T67 and the like.

上記目的を達成するために本発明は、
ユーザにより操作される操作部と、前記操作部が操作されたときに、所定の調光信号を発生させる信号発生部と、前記所定の調光信号を送信する送信部を備えた遠隔操作装置と、
前記送信部から送信された所定の調光信号を受信する受信部と、受信した調光信号に応じて調光制御を行う調光制御部とを備えた調光制御装置を含む照明装置の無線式調光制御システムであって、

前記信号発生部は、ユーザにより前記操作部が照明装置の調光レベルを高くするための最初の第１操作又は調光レベルを低くするための最初の第２操作がなされると、その最初の第１操作又は第２操作から第１所定時間内に行われた第１操作又は第２操作の回数又は持続時間をカウントし、前記第１所定時間経過後、カウントした回数又は持続時間及び操作の種類に応じた調光信号を発生し、

A remote control device comprising: an operation unit operated by a user; a signal generation unit that generates a predetermined dimming signal when the operation unit is operated; and a transmission unit that transmits the predetermined dimming signal; ,
Wireless lighting device including a dimming control device including a receiving unit that receives a predetermined dimming signal transmitted from the transmission unit and a dimming control unit that performs dimming control according to the received dimming signal Type dimming control system,
Radio communication system using radio waves in which a predetermined transmission available time for transmitting a signal and a predetermined transmission prohibition period after completion of signal transmission are set for transmission / reception of a signal between the remote control device and the lighting device Use
When the user performs the first first operation for increasing the dimming level of the lighting device or the first second operation for decreasing the dimming level by the user, the signal generating unit performs the first operation. The number or duration of the first operation or the second operation performed within the first predetermined time from the first operation or the second operation is counted, and after the first predetermined time has elapsed, the counted number or duration and the operation A dimming signal is generated according to the type,
When the dimming signal is generated by the signal generating unit, the transmitting unit modulates and transmits the dimming signal for a second predetermined time,
The dimming control unit is capable of controlling the dimming level of the lighting device in a plurality of stages. When the receiving unit receives the dimming signal, the number of times or the duration and operation of the dimming level of the lighting device are counted. The dimming control is performed so as to increase or decrease depending on the type of
When the first operation or the second operation is performed again after the transmission unit transmits the dimming signal and before the transmission prohibition period elapses, the signal generation unit The first predetermined time is variable so that the sum of the time from the completion of transmission to the new first operation or the second operation and the first predetermined time is equal to or longer than the transmission prohibition period. .

本発明によれば、第１所定時間内に行われた照明装置の調光レベルを高くするための第１操作又は調光レベルを低くするための第２操作の回数をカウントして、第１所定時間経過後、１つの調光信号として調光制御装置に送信するので、１回の調光制御における調光信号送信時間は第２所定時間にしか過ぎず、操作ボタンなどが押されている間、連続的に又は一定間隔で所定の信号を出力し続ける従来の無線式調光制御システムと比較して、信号の送信時間が短く、遠隔操作装置の電力消費を低減し、電池寿命を延ばすことが可能である。また、調光信号の送受信に、例えば特定小電力無線通信方式の規格（ＳＴＤ−Ｔ６７）による電波通信を用いた場合、この無線式調光制御システムの遠隔操作装置が調光信号の送信を完了した後、一定の送信禁止期間（例えば２秒間）は新たな信号の送信ができない。あるいは、他の遠隔操作装置が信号の送受信を行っている場合、所定の送信可能期間（例えば５秒）が終了するまで、この無線式調光制御システムの遠隔操作装置は調光信号を送信することができない。そのため、従来の無線式調光制御システムのように第１操作又は第２操作に応じてその都度調光信号を送信しようとしても、送信部によって送信することはできず、当該調光信号が失報する可能性がある。しかしながら、請求項１の発明によれば、送信部が、調光信号の送信が可能になった時点で１つの調光信号を送信するだけであるので、送信禁止期間などに起因して調光信号が失報することはない。 According to the present invention , the first operation for increasing the dimming level of the lighting device performed within the first predetermined time or the second operation for decreasing the dimming level is counted, and the first operation is performed. After the predetermined time has elapsed, the light control signal is transmitted as one light control signal to the light control device, so the light control signal transmission time in one light control is only the second predetermined time, and an operation button or the like is pressed. Compared to the conventional wireless dimming control system that continuously outputs a predetermined signal continuously or at regular intervals, the signal transmission time is short, the power consumption of the remote control device is reduced, and the battery life is extended. It is possible. In addition, for example, when radio wave communication according to a specific low power wireless communication standard (STD-T67) is used for transmission / reception of a dimming signal, the remote control device of this wireless dimming control system completes transmission of the dimming signal After that, a new signal cannot be transmitted during a certain transmission prohibition period (for example, 2 seconds). Alternatively, when another remote control device is transmitting and receiving signals, the remote control device of this wireless dimming control system transmits a dimming signal until a predetermined transmission possible period (for example, 5 seconds) ends. I can't. For this reason, even if an attempt is made to transmit a dimming signal each time according to the first operation or the second operation as in the conventional wireless dimming control system, the dimming signal cannot be transmitted by the transmitter, and the dimming signal is lost. There is a possibility to report. However, according to the invention of claim 1, the transmitter only transmits one dimming signal when the dimming signal can be transmitted. The signal will not be missed.

調光信号の送受信に、例えば特定小電力無線通信方式の規格（ＳＴＤ−Ｔ６７）による電波通信を用いた場合において、ユーザが第１操作又は第２操作を行い、調光制御を行っている間に上記送信可能期間が経過すると、調光信号の送信は強制的に停止される。しかしながら、送信禁止期間は送信可能期間に比べて短いため、ユーザは調光信号が送信されておらず、調光制御が行われていないことに気付かない場合が多い。そのため、送信禁止期間中においても第１操作又は第２操作が行われる可能性は高い。その場合、送信禁止期間中に最初に第１操作又は第２操作が行われてから第１所定時間をカウントすると、前回調光信号が送信されてから次に調光信号が送信されるまでの時間が送信禁止期間よりも長くなり、調光制御が不自然になる可能性がある。そこで、第１所定時間を、送信部が最後に信号を送信してから最初の第１操作又は第２操作が行われるまでの時間に応じて可変としているので、前回調光信号が送信されてから次に調光信号が送信されるまでの時間を、最短で送信禁止期間と同じ時間（例えば２秒）にまで短縮することができる。 For example, when radio communication according to a specific low power wireless communication standard (STD-T67) is used for transmission / reception of a dimming signal, the user performs the first operation or the second operation and performs dimming control. When the transmittable period elapses, the transmission of the dimming signal is forcibly stopped. However, since the transmission prohibition period is shorter than the transmission possible period, the user often does not notice that the dimming signal is not transmitted and the dimming control is not performed. Therefore, there is a high possibility that the first operation or the second operation is performed even during the transmission prohibition period. In that case, when the first predetermined time is counted after the first operation or the second operation is first performed during the transmission prohibition period, the time from when the previous dimming signal is transmitted until the next dimming signal is transmitted. The time becomes longer than the transmission prohibition period, and the dimming control may become unnatural. Wherein, the first predetermined time, the transmission unit is the last initial of the first operation from the transmission of the signal or the second operation is variable in accordance with time to take place, it is sent last dimming signal Then, the time until the next dimming signal is transmitted can be shortened to the same time (for example, 2 seconds) as the transmission prohibition period.

本発明の一実施形態に係る無線式調光制御システムについて、図面を参照しつつ説明する。図１に示すように、本実施形態に係る無線式調光制御システム１は、ユーザによって操作される遠隔操作装置１０と、遠隔操作装置１０から送信される信号を受信して、受信した信号の示す内容に応じて照明装置３０を調光制御する（照明のオン／オフを含む）調光制御装置２０で構成されている。調光制御装置２０は、照明装置３０の制御回路（例えばインバータ回路）と共に一体的に構成されていてもよいし、照明装置３０とは独立して構成され、複数の照明装置３０を同時に調光制御するものであってもよい。遠隔操作装置１０は、従来から用いられている赤外線を信号の送受信に用いるものであってもよいし、特定小電力無線通信方式の規格（ＳＴＤ−Ｔ６７）による電波通信を用いたものであってもよい。   A wireless dimming control system according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the wireless dimming control system 1 according to the present embodiment receives a remote operation device 10 operated by a user and a signal transmitted from the remote operation device 10, and receives the received signal. The light control device 20 includes a light control device 20 that controls light control (including lighting on / off) according to the contents to be shown. The dimming control device 20 may be configured integrally with a control circuit (for example, an inverter circuit) of the lighting device 30 or may be configured independently of the lighting device 30 and simultaneously control the plurality of lighting devices 30. It may be controlled. The remote control device 10 may be one that uses conventionally used infrared rays for signal transmission or reception, or one that uses radio wave communication according to the standard (STD-T67) of a specific low power wireless communication system. Also good.

遠隔操作装置１０は、ユーザにより操作され、照明装置の点灯及び消灯を制御する点灯ボタン（例えば、◎ボタン）及び消灯ボタン（例えば、□ボタン）、調光レベルを高くするための調光アップボタン（例えば、△ボタン）及び調光レベルを低くするための調光ダウンボタン（例えば、▽ボタン）などの複数のスイッチで構成された操作部１１と、操作部１１が操作されたときに、所定の調光信号を発生させるＣＰＵ、ＲＯＭ、ＲＡＭなどで構成された信号発生部１２と、所定の調光信号を変調して送信する赤外線ＬＥＤなどの発光素子又は所定の周波数の電波を発振する発振回路などで構成された送信部１３などを備えている。なお、遠隔操作装置１０は、必ずしもリモコン装置のようにユーザが手持ちで操作できるものに限られず、壁面に設けられた操作パネルなどであってもよい。   The remote operation device 10 is operated by a user, and a lighting button (for example, ◎ button) and a light-off button (for example, □ button) for controlling turning on and off of the lighting device, and a light control up button for increasing the light control level. (For example, a Δ button) and a light control down button (for example, a ▽ button) for lowering the light control level, and an operation unit 11 configured with a plurality of switches, and a predetermined time when the operation unit 11 is operated. A signal generator 12 composed of a CPU, ROM, RAM, etc. that generates a dimming signal, and a light emitting element such as an infrared LED that modulates and transmits a predetermined dimming signal or an oscillation that oscillates a radio wave of a predetermined frequency A transmission unit 13 composed of a circuit or the like is provided. The remote operation device 10 is not necessarily limited to a device that can be operated by a user, such as a remote control device, and may be an operation panel provided on a wall surface.

調光制御装置２０は、送信部１３から送信された所定の調光信号を受信する受光素子又はアンテナ及び復調機などで構成された受信部２１と、受信した調光信号に応じて調光制御を行うＣＰＵ、ＲＯＭ、ＲＡＭなどで構成された調光制御部２２と、ユーザにより操作され、遠隔操作装置１０を介さずに直接調光制御するための操作部２３などを備えている。なお、照明装置３０は、必ずしもこの無線式調光制御システムに含まれている必要はない。   The dimming control device 20 includes a light receiving element or an antenna that receives a predetermined dimming signal transmitted from the transmitting unit 13, an antenna, a demodulator, and the like, and dimming control according to the received dimming signal. A light control unit 22 composed of a CPU, a ROM, a RAM, and the like, and an operation unit 23 that is operated by a user and directly controls light without using the remote operation device 10. The lighting device 30 is not necessarily included in the wireless dimming control system.

図２は、本実施形態に係る無線式調光制御システム１における調光制御動作の第１例を示すタイムチャートである。基本的に、この無線式調光制御システム１では、第１所定時間Ｔ１内に行われた照明装置３０の調光レベルを高くするための第１操作Ｍ１又は調光レベルを低くするための第２操作Ｍ２の回数又は持続時間をカウントして、第１所定時間Ｔ１経過後、１つの調光信号Ｓ１として調光制御装置に送信するように構成されている。   FIG. 2 is a time chart showing a first example of the dimming control operation in the wireless dimming control system 1 according to the present embodiment. Basically, in this wireless dimming control system 1, the first operation M1 for increasing the dimming level of the lighting device 30 performed within the first predetermined time T1 or the first operation for decreasing the dimming level. The number or duration of the two operations M2 is counted, and after the first predetermined time T1 has elapsed, it is configured to be transmitted to the dimming control device as one dimming signal S1.

遠隔操作装置１０の信号発生部１２は、ユーザが操作部１１の調光アップボタンを最初に操作してから（最初の第１操作Ｍ１）又は調光ダウンボタンを最初に操作してから（最初の第２操作Ｍ２）第１所定時間Ｔ１が経過するまでの間に、調光アップボタンが連続して押し続けている間（第１操作Ｍ１）又は調光ダウンボタンが連続して押し続けている間（第２操作Ｍ２）、その調光アップボタン又は調光ダウンボタンが押し続けられている時間をカウントする。あるいは、信号発生部１２は、ユーザが調光アップボタン又は調光ダウンボタンを押している時間が所定の時間よりも短い場合は、ユーザが一度調光アップボタンを操作するか（第１操作Ｍ１）又は調光ダウンボタンを操作する（第２操作Ｍ２）ごとに、操作回数をカウントする。そして、第１所定時間Ｔ１が経過すると、信号発生部１２は、その間にカウントした操作回数又は持続時間及び操作の種類に応じた１つの調光信号Ｓ１を発生する。送信部１３は、信号発生部１２により調光信号Ｓ１が発生されると、第２所定時間Ｔ２だけ調光信号Ｓ１を変調して送信する。なお、第１所定時間Ｔ１内に、調光アップボタンと調光ダウンボタンが操作されたときは、調光アップボタンが１度操作されるとカウンタのカウント数を＋１、調光ダウンボタンが１度操作されるとカウンタのカウント数を−１とする。   The signal generation unit 12 of the remote control device 10 operates after the user first operates the dimming up button of the operation unit 11 (first first operation M1) or first operates the dimming down button (first The second operation M2) While the dimming up button is continuously pressed until the first predetermined time T1 elapses (first operation M1) or the dimming down button is continuously pressed. During this time (second operation M2), the time during which the dimming up button or dimming down button is kept pressed is counted. Alternatively, when the time during which the user is pressing the dimming up button or the dimming down button is shorter than a predetermined time, the signal generating unit 12 operates the dimming up button once (first operation M1). Alternatively, the number of operations is counted each time the dimming down button is operated (second operation M2). And when the 1st predetermined time T1 passes, the signal generation part 12 will generate | occur | produce one dimming signal S1 according to the frequency | count of operation or duration counted during that time, and the kind of operation. When the dimming signal S1 is generated by the signal generating unit 12, the transmitting unit 13 modulates and transmits the dimming signal S1 for the second predetermined time T2. When the dimming up button and the dimming down button are operated within the first predetermined time T1, when the dimming up button is operated once, the count number of the counter is +1 and the dimming down button is 1. Each time, the counter count is set to -1.

なお、調光信号Ｓ１は、少なくとも、調光アップか調光ダウンかの情報及び調光段数の情報を含んでおり、その他の情報を含んでいてもよい。例えば、無線式調光制御システム１が複数の遠隔操作装置１０及び複数の調光制御装置２０で構成されている場合は、各調光制御装置２０及び照明装置３０に識別番号を設定し、遠隔操作装置１０から送信される調光信号Ｓ１に識別番号を付与することにより、各遠隔操作装置１０から、任意の調光制御装置２０に接続された全ての照明装置３０又は任意の照明装置３０を特定して、調光制御することが可能である。   The dimming signal S1 includes at least information on whether the dimming is up or down, and information on the number of dimming stages, and may include other information. For example, when the wireless dimming control system 1 is composed of a plurality of remote control devices 10 and a plurality of dimming control devices 20, an identification number is set for each dimming control device 20 and the lighting device 30, and remote control is performed. By assigning an identification number to the dimming signal S1 transmitted from the operation device 10, all the illuminating devices 30 or arbitrary illuminating devices 30 connected to any dimming control device 20 from each remote control device 10 are displayed. Specifically, dimming control can be performed.

遠隔操作装置１０の送信部１３から調光信号Ｓ１が送信され、調光制御装置２０の受信部２１が調光信号Ｓ１を受信すると、調光制御部２２は、照明装置３０の調光レベルをカウントした回数又は持続時間及び操作の種類に応じて高く又は低くするように調光制御を開始する。ここで、調光制御装置２０の調光制御部２２は、以下に述べる３つのパターンのいずれかで、照明装置３０の調光レベルを変化させることが可能である。   When the dimming signal S1 is transmitted from the transmission unit 13 of the remote operation device 10 and the receiving unit 21 of the dimming control device 20 receives the dimming signal S1, the dimming control unit 22 sets the dimming level of the lighting device 30. Dimming control is started so as to increase or decrease according to the counted number or duration and the type of operation. Here, the dimming control unit 22 of the dimming control device 20 can change the dimming level of the lighting device 30 in any of the three patterns described below.

調光制御のケース１では、調光制御部２２は、受信部２１が調光信号Ｓ１を受信すると、照明装置３０の調光レベルを、現在の調光レベルからカウントした回数又は持続時間分だけ上又は下の調光レベルに一気に調光制御する。この場合、カウントした回数又は持続時間によっては、明らかに照明装置３０の調光レベルが変化したことをユーザが認識する可能性があるけれども、速やかにユーザが希望する調光レベルを得ることができる。   In case 1 of dimming control, when the receiving unit 21 receives the dimming signal S1, the dimming control unit 22 counts the dimming level of the lighting device 30 from the current dimming level or the duration. Dimming control is performed at a stretch to the dimming level above or below. In this case, although the user may clearly recognize that the dimming level of the lighting device 30 has changed depending on the counted number or duration, the dimming level desired by the user can be quickly obtained. .

ケース２では、調光制御部２２は、受信部２１が調光信号Ｓ１を受信すると、そこから比較的短い第３所定時間Ｔ３経過するまでの間、照明装置３０の調光レベルを、現在の調光レベルからカウントした回数又は持続時間分だけ上又は下の調光レベルに１段階ずつ段階的に調光制御する。この場合、上記ケース１の場合に比べて、照明装置３０の調光レベルが変化したことを目立たなくすることができる。   In case 2, when the receiving unit 21 receives the dimming signal S1, the dimming control unit 22 changes the current dimming level of the lighting device 30 until the relatively short third predetermined time T3 elapses. The dimming control is performed step by step to the dimming level that is higher or lower by the number or duration counted from the dimming level. In this case, it can be made inconspicuous that the dimming level of the illumination device 30 has changed as compared with the case 1 described above.

ケース３では、調光制御部２２は、受信部２１が調光信号Ｓ１を受信すると、そこから、比較的ゆっくりとしたタイミング、例えばユーザが遠隔操作装置１０の操作部１１の調光アップボタン又は調光ダウンボタンを操作したタイミングに合わせて、照明装置３０の調光レベルを、現在の調光レベルからカウントした回数又は持続時間分だけ上又は下の調光レベルに調光制御する。この場合、ユーザが希望する調光レベルが得られるまでに時間がかかるものの、ユーザにほとんど認識させることなく、照明装置３０の調光レベルを変化させることができる。   In case 3, when the receiving unit 21 receives the dimming signal S <b> 1, the dimming control unit 22 receives a dimming signal S <b> 1 from a relatively slow timing, e.g. In accordance with the timing at which the dimming down button is operated, the dimming control is performed so that the dimming level of the lighting device 30 is increased or decreased by the number of times or the duration counted from the current dimming level. In this case, although it takes time until the dimming level desired by the user is obtained, the dimming level of the lighting device 30 can be changed with almost no recognition by the user.

このように、この無線式調光制御システム１によれば、第１所定時間Ｔ１内に行われた照明装置３０の調光レベルを高くするための第１操作Ｍ１又は調光レベルを低くするための第２操作Ｍ２の回数又は持続時間をカウントして、第１所定時間Ｔ１経過後、１つの調光信号Ｓ１として調光制御装置に送信するので、１回の調光制御における調光信号Ｓ１の送信時間は第２所定時間Ｔ２にしか過ぎず、従来の無線式調光制御システムと比較して、信号の送信時間が短く、遠隔操作装置１０の電力消費を低減し、電池寿命を延ばすことが可能である。   Thus, according to the wireless dimming control system 1, the first operation M1 for increasing the dimming level of the lighting device 30 performed within the first predetermined time T1 or the dimming level is lowered. The number of times or the duration of the second operation M2 is counted, and after the first predetermined time T1 has elapsed, the dimming signal S1 in one dimming control is transmitted to the dimming control device as one dimming signal S1. Transmission time is only the second predetermined time T2, and compared with the conventional wireless dimming control system, the signal transmission time is short, the power consumption of the remote control device 10 is reduced, and the battery life is extended. Is possible.

特に、調光信号の送受信に、例えば特定小電力無線通信方式の規格（ＳＴＤ−Ｔ６７）による電波通信を用いた場合、遠隔操作装置１０が調光信号の送信を完了した後、一定の送信禁止期間（例えば２秒間）は新たな信号の送信ができない。あるいは、他の遠隔操作装置が信号の送受信を行っている場合、所定の送信可能期間（例えば５秒）が終了するまで、遠隔操作装置１０は調光信号を送信することができない。そのため、従来の無線式調光制御システムのように第１操作又は第２操作に応じてその都度調光信号を送信しようとしても、送信部によって送信することはできず、当該調光信号が失報する可能性がある。しかしながら、第１所定時間Ｔ１内に行われた第１操作Ｍ１又は第２操作Ｍ２の回数又は持続時間をカウントして、第１所定時間Ｔ１経過後、１つの調光信号Ｓ１として調光制御装置に送信するので、送信部１３が、調光信号の送信が可能になった時点で１つの調光信号Ｓ１を送信するだけであるので、送信禁止期間などに起因して調光信号が失報することはない。   In particular, when radio communication according to the standard (STD-T67) of the specific low power wireless communication system is used for transmission / reception of the dimming signal, for example, after the remote control device 10 completes transmission of the dimming signal, certain transmission prohibition is required. A new signal cannot be transmitted during the period (for example, 2 seconds). Alternatively, when another remote control device is transmitting and receiving signals, the remote control device 10 cannot transmit a dimming signal until a predetermined transmission possible period (for example, 5 seconds) ends. For this reason, even if an attempt is made to transmit a dimming signal each time according to the first operation or the second operation as in the conventional wireless dimming control system, the dimming signal cannot be transmitted by the transmitter, and the dimming signal is lost. There is a possibility to report. However, the number of times or the duration of the first operation M1 or the second operation M2 performed within the first predetermined time T1 is counted, and the dimming control device as one dimming signal S1 after the first predetermined time T1 has elapsed. Since the transmission unit 13 only transmits one dimming signal S1 when transmission of the dimming signal becomes possible, the dimming signal is not reported due to a transmission prohibition period or the like. Never do.

次に、本実施形態に係る無線式調光制御システム１の調光制御動作の第２例について、図３を参照しつつ説明する。調光信号の送受信に、例えば特定小電力無線通信方式の規格（ＳＴＤ−Ｔ６７）による電波通信を用いた場合において、ユーザが第１操作Ｍ１又は第２操作Ｍ２を行い、調光制御を行っている間に上記送信可能期間（例えば５秒）が経過すると、調光信号Ｓ１の送信は強制的に停止される。しかしながら、送信禁止期間（例えば２秒）は送信可能期間に比べて短いため、ユーザは調光信号が送信されておらず、調光制御が行われていないことに気付かない場合が多い。そのため、送信禁止期間中においても第１操作又は第２操作が行われる可能性は高い。その場合、送信禁止期間中に最初に第１操作Ｍ１又は第２操作Ｍ２が行われてから第１所定時間Ｔ１をカウントすると、前回調光信号Ｓ１が送信されてから次に調光信号Ｓ１’が送信されるまでの時間が送信禁止期間よりも長くなり、調光制御が不自然になる可能性がある。そこで、図３に示すように、第１所定時間Ｔ１’を、送信部１３が最後に調光信号Ｓ１を送信してから最初の第１操作Ｍ１又は第２操作Ｍ２が行われるまでの時間ΔＴに応じて可変とすることにより、前回調光信号Ｓ１が送信されてから次に調光信号Ｓ１’が送信されるまでの時間を、最短で送信禁止期間と同じ時間（例えば２秒）にまで短縮することができる。   Next, a second example of the dimming control operation of the wireless dimming control system 1 according to the present embodiment will be described with reference to FIG. For example, when radio communication according to a specific low power wireless communication standard (STD-T67) is used for transmission / reception of the dimming signal, the user performs the first operation M1 or the second operation M2 to perform dimming control. When the transmission possible period (for example, 5 seconds) elapses during the period, the transmission of the dimming signal S1 is forcibly stopped. However, since the transmission prohibition period (for example, 2 seconds) is shorter than the transmission possible period, the user often does not notice that the dimming signal is not transmitted and the dimming control is not performed. Therefore, there is a high possibility that the first operation or the second operation is performed even during the transmission prohibition period. In that case, when the first predetermined time T1 is counted after the first operation M1 or the second operation M2 is first performed during the transmission prohibition period, the dimming signal S1 ′ is next transmitted after the previous dimming signal S1 is transmitted. May be longer than the transmission prohibition period, and dimming control may become unnatural. Therefore, as shown in FIG. 3, the first predetermined time T1 ′ is the time ΔT from when the transmitter 13 last transmits the dimming signal S1 to when the first first operation M1 or the second operation M2 is performed. By making it variable according to the time, the time from the previous dimming signal S1 being transmitted until the next dimming signal S1 ′ is transmitted is the shortest to the same time as the transmission prohibition period (for example, 2 seconds). It can be shortened.
