Description

本発明は、調光制御装置から調光信号を送信して種別の異なる複数の照明端末を集中的に調光制御する調光制御システムに関する。   The present invention relates to a dimming control system that transmits a dimming signal from a dimming control device and performs dimming control on a plurality of different types of lighting terminals in a centralized manner.

複数組の調光信号回線に蛍光灯、白熱灯、LED等の種別の異なる照明端末が接続され、調光制御装置から出力される調光信号の信号形式とは異なる信号形式によって調光制御される照明端末が接続された調光信号回線には信号変換器が設けられて、1つの調光制御装置から各調光信号回線に出力される調光信号により種別の異なる複数の照明端末が集中的に調光制御できる調光制御システムが知られている(例えば、特許文献1参照)。   Different types of lighting terminals such as fluorescent lamps, incandescent lamps, and LEDs are connected to multiple sets of dimming signal lines, and dimming control is performed using a signal format different from the signal format of the dimming signal output from the dimming control device. The dimming signal line to which the lighting terminal is connected is provided with a signal converter, and a plurality of different types of lighting terminals are concentrated by the dimming signal output from each dimming control device to each dimming signal line. A dimming control system capable of performing dimming control automatically is known (for example, see Patent Document 1).

特許文献1に記載された調光制御システムのブロック構成が図15に示される。この調光制御システムでは、4系統の調光信号回線101、102、103、104を介して信号形式の異なる複数台の照明器具105、106、107、108が調光制御装置109に接続されており、調光制御装置109内の調光信号出力部110から出力される調光信号(PWM信号)に対応していない照明器具(例えば、位相制御信号によって制御される白熱灯)が接続された調光信号回線101、102、103には信号変換器111、112、113が設けられている。   FIG. 15 shows a block configuration of the dimming control system described in Patent Document 1. In this dimming control system, a plurality of lighting fixtures 105, 106, 107, 108 having different signal formats are connected to a dimming control device 109 via four dimming signal lines 101, 102, 103, 104. A lighting fixture (for example, an incandescent lamp controlled by a phase control signal) that does not correspond to the dimming signal (PWM signal) output from the dimming signal output unit 110 in the dimming control device 109 is connected. Signal converters 111, 112, and 113 are provided in the dimming signal lines 101, 102, and 103.

また、信号変換器111、112、113には、調光信号を照明器具105、106、107、108の種別に応じて所定時間短絡する(又は、調光信号を所定電圧に変更する)信号短絡部が備えられ、調光制御装置109には、調光信号回線ごとに調光信号の短絡時間(又は、電圧)を検出する短絡検出部114(又は、電圧検出部)と、照明器具の種別ごとの標準的な短絡時間(又は、電圧)を記憶しておく記憶部115が備えられて、調光制御装置109自体が、各系統に接続された照明器具105、106、107、108の種別を判断できるようになっており、照明システムを施工する際や照明器具の種類を変更する際のユーザの手間が省けるようになっている。   Further, the signal converters 111, 112, and 113 are short-circuited for a predetermined time according to the type of the lighting fixtures 105, 106, 107, and 108 (or changed to a predetermined voltage). The dimming control device 109 includes a short circuit detection unit 114 (or voltage detection unit) that detects a short circuit time (or voltage) of the dimming signal for each dimming signal line, and a type of lighting fixture. A storage unit 115 that stores a standard short-circuit time (or voltage) for each of the lighting devices 105, 106, 107, and 108 is connected to each system. Therefore, it is possible to save the user's trouble when constructing the lighting system or changing the type of the lighting fixture.

一方、照明器具の寿命をユーザに告知する手段として、照明器具の調光制御部と、該調光制御部へ調光制御信号を送信する外部コントローラとを接続する信号線に、該信号線を短絡又は開放する手段を設けた照明システムが知られている(例えば、特許文献2参照)。

On the other hand, as means for notifying the user of the lifetime of the lighting fixture, the signal line is connected to a signal line connecting the dimming control unit of the lighting fixture and an external controller that transmits a dimming control signal to the dimming control unit. An illumination system provided with a means for short-circuiting or opening is known (see, for example, Patent Document 2).

ところで、上記のような複数組の調光信号回線に対して1つの調光制御装置から調光信号を送信して複数台の照明器具を集中的に調光制御する調光制御システムにおいては、各調光信号回線に複数台の照明器具が接続される場合が多いのであるが、特許文献1に記載された調光制御システムでは、調光制御装置が各調光信号回線に調光信号を出力するときの調光信号に与えられる短絡時間(又は、電圧変化)によって照明器具の種別を判定するようになっているので、各調光信号回線に接続された複数台の照明器具の中に種別の異なる照明器具が混在していてもそれを検出することが困難である。   By the way, in the dimming control system that intensively controls dimming of a plurality of lighting fixtures by transmitting a dimming signal from one dimming control device to a plurality of sets of dimming signal lines as described above, In many cases, a plurality of lighting fixtures are connected to each dimming signal line. However, in the dimming control system described in Patent Document 1, the dimming control device sends a dimming signal to each dimming signal line. Since the type of lighting fixture is determined based on the short-circuit time (or voltage change) given to the dimming signal at the time of output, among the multiple lighting fixtures connected to each dimming signal line Even if different types of lighting fixtures are mixed, it is difficult to detect them.

例えば、特許文献1に記載された調光制御システムでは、特定の調光信号回線に、短絡時間が短く設定された照明器具と短絡時間が長く設定された照明器具が混在して接続されている場合、短絡時間が短く設定された照明器具の存在は検出されないという不具合がある。   For example, in the dimming control system described in Patent Document 1, a lighting device with a short-circuit time set short and a lighting device with a short-circuit time set are mixedly connected to a specific dimming signal line. In this case, there is a problem in that the presence of a lighting fixture whose short-circuit time is set short is not detected.

特許文献2に記載の照明システムは、調光制御信号を送信する信号線を短絡することによって外部コントローラを操作不能とし、そのことによってユーザが照明器具の寿命に気付くように構成したものであって、照明器具の種別を判定するものではない。   The lighting system described in Patent Document 2 is configured such that the external controller is made inoperable by short-circuiting a signal line that transmits a dimming control signal, thereby allowing the user to notice the life of the lighting fixture. It does not determine the type of lighting fixture.

そこで、本発明は、複数組の調光信号回線に種別の異なる照明端末がそれぞれ接続されて成る調光制御システムにおいて、各照明端末の種別をより正しく判定することができ、また、各調光信号回線に複数の照明端末が接続される場合に、該複数の照明端末が同一の種別でないことを検出することができる調光制御システムを提供することを目的とする。   Therefore, the present invention can more accurately determine the type of each lighting terminal in a dimming control system in which different types of lighting terminals are connected to a plurality of sets of dimming signal lines, and each dimming An object of the present invention is to provide a dimming control system capable of detecting that a plurality of lighting terminals are not of the same type when a plurality of lighting terminals are connected to a signal line.

The dimming control information corresponding to the type determined by is read from the storage means, and a dimming signal is transmitted to each lighting terminal based on the read dimming control information.

請求項3の発明は、請求項1に記載の調光制御システムにおいて、前記調光制御装置は、前記電流測定手段によって測定された前記調光信号回線ごとの短絡電流の値が、前記照明端末の種別に応じた短絡電流の値の整数倍でない場合に、当該調光信号回線において種別の異なる照明端末が接続されていることを検出する異常検出手段を、さらに備えることを特徴とする。   According to a third aspect of the present invention, there is provided the dimming control system according to the first aspect, wherein the dimming control device has a value of a short-circuit current for each of the dimming signal lines measured by the current measuring unit. In the case where it is not an integral multiple of the value of the short-circuit current according to the type, an abnormality detecting means for detecting that a lighting terminal of a different type is connected in the dimming signal line is further provided.

請求項1の発明によれば、調光制御装置が各調光信号回線に生じる短絡電流を測定し、測定した電流値に基づいて各調光信号回線に接続された照明端末の種別を判定するので、各調光信号回線に接続された照明端末の種別をより正しく判定することができ、さらには、各調光信号回線に複数種類の照明端末が接続される場合に、該複数の照明端末が同一の種別でないことを検出することができる。   According to the invention of claim 1, the dimming control device measures the short-circuit current generated in each dimming signal line, and determines the type of the lighting terminal connected to each dimming signal line based on the measured current value. Therefore, it is possible to more correctly determine the type of lighting terminal connected to each dimming signal line. Furthermore, when a plurality of types of lighting terminals are connected to each dimming signal line, the plurality of lighting terminals Are not the same type.

請求項2の発明によれば、請求項1の発明の効果に加えて、調光制御装置が、判定した種別に応じた調光制御情報を記憶手段から読出し、読出した調光制御情報に基づいて調光信号を送信するので、各照明端末が種別ごとに正しい調光状態で点灯する。   According to the invention of claim 2, in addition to the effect of the invention of claim 1, the dimming control device reads the dimming control information corresponding to the determined type from the storage means, and based on the read dimming control information Therefore, each lighting terminal is lit in the correct dimming state for each type.

Since the abnormality detecting means for detecting that the lighting terminal is connected to the same dimming signal line is provided, an abnormality such as a wiring error can be easily and correctly detected.

以下、本発明の一実施形態に係る調光制御システムについて、図1乃至図14を参照して説明する。本実施形態の調光制御システム1は、図1に示されるように、4組の調光信号回線L1、L2、L3、L4に対して調光信号を送信する調光制御装置2と、ユーザが操作して調光制御装置2に対して操作信号を出力するリモコン3と、4組の調光信号回線L1、L2、L3、L4にそれぞれ接続された種別の異なる照明端末としての蛍光灯照明器具Fa、Fb、白熱灯照明器具R、及びLED照明器具Eとを備える。   Hereinafter, a dimming control system according to an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the dimming control system 1 of this embodiment includes a dimming control device 2 that transmits dimming signals to four sets of dimming signal lines L1, L2, L3, and L4, and a user. Operates a remote controller 3 that outputs an operation signal to the dimming control device 2, and fluorescent lamp illumination as different types of lighting terminals respectively connected to the four dimming signal lines L1, L2, L3, and L4 The fixtures Fa and Fb, the incandescent lamp lighting fixture R, and the LED lighting fixture E are provided.

各照明端末Fa、Fb、R、Eは、それぞれ調光信号回線L1、L2、L3、L4を一時的に短絡する回線短絡装置36、45、55を備えている。調光信号回線L1、L2、L3、L4は、図1では1本の線に示されているが、実際には並行した2本の線から構成される。   Each of the lighting terminals Fa, Fb, R, and E includes line short-circuit devices 36, 45, and 55 that temporarily short-circuit the dimming signal lines L1, L2, L3, and L4, respectively. The dimming signal lines L1, L2, L3, and L4 are shown as one line in FIG. 1, but are actually composed of two parallel lines.

蛍光灯照明器具Fa、Fb、白熱灯照明器具R、及びLED照明器具Eは、それぞれ複数台が各調光信号回線L1、L2、L3、L4に対して並列に接続されており、例えば、本調光制御システム1がオフィスの照明設備として設けられる場合には、調光信号回線L1に接続された蛍光灯照明器具Fa1、Fa2・・のグループ、調光信号回線L2に接続された蛍光灯照明器具Fb1、Fb2・・のグループ、調光信号回線L3に接続された白熱灯照明器具R1、R2・・のグループ、及び調光信号回線L4に接続されたLED照明器具E1、E2・・のグループが、それぞれオフィスの別々の領域を照明するように配置される。   A plurality of fluorescent lamp luminaires Fa and Fb, incandescent lamp luminaires R, and LED luminaires E are connected in parallel to the dimming signal lines L1, L2, L3, and L4. When the dimming control system 1 is provided as an office lighting facility, the fluorescent lamp luminaires Fa1, Fa2,... Connected to the dimming signal line L1, and the fluorescent lamp illumination connected to the dimming signal line L2. A group of fixtures Fb1, Fb2,..., A group of incandescent lamp luminaires R1, R2... Connected to the dimming signal line L3, and a group of LED lighting fixtures E1, E2. Are each arranged to illuminate a separate area of the office.

調光制御装置2は、商用電源21から電源回路22を介して所定の動作電圧を供給されるマイクロプロセッサ23(種別判定手段)と、マイクロプロセッサ23によって制御され各調光信号回線L1、L2、L3、L4に所定の調光信号S(PWM信号)を出力する調光信号出力回路24と、各調光信号回線L1、L2、L3、L4に流れる短絡電流を測定し測定値をマイクロプロセッサ23へ出力する短絡電流値測定回路25と、照明器具の種別ごとの調光制御情報(後述)等を記憶した記憶部26(記憶手段)と、リモコン3から送出される赤外線を受光し赤外線に重畳された指令信号をマイクロプロセッサ23へ出力する赤外線受光部27を備える。図1では、赤外線受光部27を使用しているが、受光部は、赤外線を受光するものに限られず、特定小電力無線その他の電波を受信するものでもよい。   The dimming control device 2 includes a microprocessor 23 (type determining means) to which a predetermined operating voltage is supplied from a commercial power supply 21 via a power supply circuit 22, and each dimming signal line L1, L2, A dimming signal output circuit 24 that outputs a predetermined dimming signal S (PWM signal) to L3 and L4, and a short circuit current flowing through each of the dimming signal lines L1, L2, L3, and L4 is measured, and the measured value is measured by the microprocessor 23. Short-circuit current value measuring circuit 25 to be output to, storage unit 26 (storage means) storing dimming control information (described later) for each type of lighting fixture, and infrared rays transmitted from remote controller 3 are received and superimposed on the infrared rays An infrared light receiving unit 27 for outputting the command signal thus output to the microprocessor 23 is provided. Although the infrared light receiving unit 27 is used in FIG. 1, the light receiving unit is not limited to the one that receives infrared rays, and may be a specific low power radio or other type that receives radio waves.

調光信号出力回路24から出力される調光信号S(PWM信号)の例が図2に示される。PWM信号Sは、一定の周期Tと電圧Vを有し、マイクロプロセッサ23からの指示に応じてオンデューティ(周期Tに対するオン時間t1の割合)の値が変化する。   An example of the dimming signal S (PWM signal) output from the dimming signal output circuit 24 is shown in FIG. The PWM signal S has a constant period T and a voltage V, and the value of the on-duty (the ratio of the on-time t1 to the period T) changes according to an instruction from the microprocessor 23.

各照明端末Fa、Fb、R、Eは、入力されるPWM信号Sのオンデューティの値に応じて光出力が変化する。本実施形態における各照明端末Fa、Fb、R、Eのオンデューティ値に対応する光出力値が図3及び図4に示される。白熱灯照明器具Rと蛍光灯照明器具Fa、Fbでは、オンデューティ値の増加にほぼ比例して光出力が減少し、LED照明器具Eでは、オンデューティ値の増加に対して光出力が指数関数状に増加する。   The light output of each lighting terminal Fa, Fb, R, E changes according to the on-duty value of the input PWM signal S. The light output values corresponding to the on-duty values of the lighting terminals Fa, Fb, R, and E in the present embodiment are shown in FIGS. In the incandescent lamp luminaire R and the fluorescent lamp luminaires Fa and Fb, the light output decreases almost in proportion to the increase in the on-duty value, and in the LED luminaire E, the light output is an exponential function with respect to the increase in the on-duty value. Increase in shape.

上記各照明端末Fa、Fb、R、Eごとのオンデューティ値に対応する光出力値の関係を示すテーブルT1が、調光制御情報として記憶部26に記憶されている。   A table T1 indicating the relationship between the light output values corresponding to the on-duty values for each of the lighting terminals Fa, Fb, R, and E is stored in the storage unit 26 as dimming control information.

蛍光灯照明器具Faは、図5に示されるように、商用電源21から電源回路32を介して電源を供給され、電源回路32によって所定の電圧に変換された電力の発振周期を蛍光灯33の点灯周期に変換する発振回路34と、発振回路34によって変換される発振周期を調光信号S(PWM信号)に応じた値に制御する発振周期制御部35と、発振回路34によって変換された発振周期に応じて光出力が変化する蛍光灯33と、調光信号回線L1を所定の時間短絡する回線短絡装置36とを備える。   As shown in FIG. 5, the fluorescent lamp luminaire Fa is supplied with power from the commercial power supply 21 via the power supply circuit 32, and the oscillation cycle of the electric power converted into a predetermined voltage by the power supply circuit 32 is set in the fluorescent lamp 33. An oscillation circuit 34 for converting to a lighting cycle, an oscillation cycle control unit 35 for controlling the oscillation cycle converted by the oscillation circuit 34 to a value corresponding to the dimming signal S (PWM signal), and the oscillation converted by the oscillation circuit 34 A fluorescent lamp 33 whose light output changes according to the cycle and a line short-circuit device 36 for short-circuiting the dimming signal line L1 for a predetermined time are provided.

具体的には、発振周期制御部35は、例えばオンデューティ値90%のPWM信号Sが調光信号回線L1を介して入力されたとき、そのPWM信号Sに応じて発振回路34の発振周期を制御し、蛍光灯33を11%の光出力とする(図3、図4参照)。   Specifically, for example, when the PWM signal S having an on-duty value of 90% is input via the dimming signal line L1, the oscillation cycle control unit 35 sets the oscillation cycle of the oscillation circuit 34 according to the PWM signal S. The fluorescent lamp 33 is controlled to have an optical output of 11% (see FIGS. 3 and 4).

回線短絡装置36は、図6に示されるように、並行な調光信号回線L1間に亘って接続された通常オフのトランジスタ37と、抵抗38と、トランジスタ37のオンオフを制御するタイマ回路39を備える。抵抗38の値は、照明端末の種別に応じた別々の値に設定されており、照明端末が蛍光灯照明器具Fa、Fbの場合には、抵抗値Rfに設定される。   As shown in FIG. 6, the line short-circuit device 36 includes a normally-off transistor 37, a resistor 38, and a timer circuit 39 for controlling on / off of the transistor 37 connected between the parallel dimming signal lines L1. Prepare. The value of the resistor 38 is set to a different value according to the type of the lighting terminal, and is set to the resistance value Rf when the lighting terminal is the fluorescent lamp luminaires Fa and Fb.

タイマ回路39は、マイクロプロセッサ39aを搭載した電子回路であり、蛍光灯照明器具Faの電源回路32の電源オンを検出し、その検出と同時にタイマをオンすると共にトランジスタ37をオンに切替え、所定の時間経過後にタイマをオフすると共にトランジスタ37をオフに切替えることによって調光信号回線L1を所定時間短絡する。マイクロプロセッサ39aに替えて、マイコン、汎用ICといったものでもよい。   The timer circuit 39 is an electronic circuit on which a microprocessor 39a is mounted. The timer circuit 39 detects the power-on of the power circuit 32 of the fluorescent lamp luminaire Fa, turns on the timer simultaneously with the detection and switches the transistor 37 on. After the time has elapsed, the timer is turned off and the transistor 37 is turned off to short-circuit the dimming signal line L1 for a predetermined time. Instead of the microprocessor 39a, a microcomputer, a general-purpose IC, or the like may be used.

タイマ回路39のオンオフタイミング、蛍光灯照明器具Faの電源オンのタイミング、及び調光制御装置2の電源オンのタイミングが図7に示される。調光制御装置2の電源が時刻taにオンされた後、蛍光灯照明器具Faの電源が時刻tbにオンされ、同時にタイマ回路39のタイマがオンして短絡電流Iが調光信号回線L1に流れる。タイマ回路39は所定時間td後の時刻tcにオフし、短絡電流Iが停止される。   The on / off timing of the timer circuit 39, the power-on timing of the fluorescent lamp luminaire Fa, and the power-on timing of the dimming control device 2 are shown in FIG. After the power source of the dimming control device 2 is turned on at time ta, the power source of the fluorescent lamp luminaire Fa is turned on at time tb. At the same time, the timer of the timer circuit 39 is turned on and the short-circuit current I is applied to the dimming signal line L1. Flowing. The timer circuit 39 is turned off at time tc after a predetermined time td, and the short circuit current I is stopped.

ここで、調光制御装置2は、電源オンの直後に調光信号回線L1に対してオンデューティ値100%の調光信号S(PWM信号)を送信し、その調光信号Sの電圧がEvであるとすると、蛍光灯照明器具Faの接続された調光信号回線L1には、所定時間tdだけIf=(Ev÷Rf)の短絡電流が流れる。   Here, immediately after the power is turned on, the dimming control device 2 transmits a dimming signal S (PWM signal) having an on-duty value of 100% to the dimming signal line L1, and the voltage of the dimming signal S is Ev. Assuming that, a short-circuit current of If = (Ev ÷ Rf) flows through the dimming signal line L1 to which the fluorescent lamp luminaire Fa is connected for a predetermined time td.

調光信号回線L2に接続された蛍光灯照明器具Fbの構成、及び蛍光灯照明器具Fb内の回線短絡装置36の構成は、調光信号回線L1に接続された蛍光灯照明器具Fa、及び回線短絡装置36と同一であるので説明を省略する。   The configuration of the fluorescent lamp luminaire Fb connected to the dimming signal line L2 and the configuration of the line short circuit device 36 in the fluorescent lamp luminaire Fb include the fluorescent lamp luminaire Fa and the line connected to the dimming signal line L1. Since it is the same as the short circuit device 36, description is abbreviate | omitted.

次に、白熱灯照明器具Rについて、図8を参照して説明する。白熱灯照明器具Rは、商用電源21から電源回路42を介して電源を供給され、電源回路42によって所定の電圧に変換された電力の出力位相角を、調光信号S(PWM信号)に応じた値に変換する信号変換部43と、信号変換部43によって所定の出力位相角に変換された電力に応じて光出力が変化する白熱灯44と、調光信号回線L3を所定の時間短絡する回線短絡装置45とを備える。   Next, the incandescent lamp luminaire R will be described with reference to FIG. The incandescent lamp luminaire R is supplied with power from the commercial power supply 21 via the power supply circuit 42, and the output phase angle of the power converted into a predetermined voltage by the power supply circuit 42 is determined according to the dimming signal S (PWM signal). The signal conversion unit 43 that converts the light output value to the predetermined value, the incandescent lamp 44 whose light output changes according to the electric power converted to the predetermined output phase angle by the signal conversion unit 43, and the dimming signal line L3 are short-circuited for a predetermined time. A line short-circuit device 45.

具体的には、信号変換部43は、例えばオンデューティ値98%のPWM信号Sが入力されたとき、そのPWM信号に応じて出力位相角を178度に制御し、白熱灯44の光出力が2%になる。調光信号S(PWM信号)のオンデューティ値に対する出力位相角の例が図9のテーブルT2に示される。図9に示されるテーブルT2の内容は、信号変換部43に記憶されている。   Specifically, for example, when a PWM signal S with an on-duty value of 98% is input, the signal conversion unit 43 controls the output phase angle to 178 degrees according to the PWM signal, and the light output of the incandescent lamp 44 is 2%. An example of the output phase angle with respect to the on-duty value of the dimming signal S (PWM signal) is shown in a table T2 of FIG. The contents of the table T2 shown in FIG. 9 are stored in the signal conversion unit 43.

白熱灯照明器具Rに備えられる回線短絡装置45の構成は、蛍光灯照明器具Fa、Fbに備えられた回線短絡装置36と同一であり説明を省略するが、白熱灯照明器具Rに備えられる回線短絡装置45の抵抗の抵抗値Rrは、蛍光灯照明器具Fa、Fbに備えられた回線短絡装置36の抵抗の抵抗値Rfとは異なった値に設定される。   The configuration of the line short-circuiting device 45 provided in the incandescent lamp lighting fixture R is the same as that of the line short-circuiting device 36 provided in the fluorescent lamp lighting fixtures Fa and Fb, and the description thereof is omitted. The resistance value Rr of the resistance of the short-circuit device 45 is set to a value different from the resistance value Rf of the resistance of the line short-circuit device 36 provided in the fluorescent lamp luminaires Fa and Fb.

従って、調光制御装置2の電源がオンされた直後に、調光制御装置2が調光信号回線L3にオンデューティ値100%の調光信号S(PWM信号)を送信したとき、調光信号回線L3が所定時間tdだけ短絡され、Ir=(Ev÷Rr)の短絡電流が流れる。   Accordingly, when the dimming control device 2 transmits a dimming signal S (PWM signal) having an on-duty value of 100% to the dimming signal line L3 immediately after the power of the dimming control device 2 is turned on, the dimming signal The line L3 is short-circuited for a predetermined time td, and a short-circuit current of Ir = (Ev ÷ Rr) flows.

次に、LED照明器具Eについて、図10を参照して説明する。LED照明器具Eは、商用電源21から電源回路52を介して電源を供給され、電源回路52によって所定の電圧に変換された電力の出力位相角を、調光信号S(PWM信号)に応じた値に変換する信号変換部53と、信号変換部53によって所定の位相角に変換された電力に応じて光出力が変化するLED54と、調光信号回線L4を所定の時間短絡する回線短絡装置55とを備える。   Next, the LED lighting apparatus E will be described with reference to FIG. The LED lighting apparatus E is supplied with power from the commercial power supply 21 via the power supply circuit 52, and the output phase angle of the electric power converted into a predetermined voltage by the power supply circuit 52 corresponds to the dimming signal S (PWM signal). A signal conversion unit 53 that converts the value into a value, an LED 54 whose light output changes according to the power converted to a predetermined phase angle by the signal conversion unit 53, and a line short-circuit device 55 that short-circuits the dimming signal line L4 for a predetermined time. With.

具体的には、信号変換部53は、例えばオンデューティ値99%のPWM信号Sが入力されたとき、そのPWM信号Sに応じて出力位相角を179度に制御し、LED54の光出力は98%になる。白熱灯照明器具Rと同様に、調光信号S(PWM信号)のオンデューティ値に対する出力位相角のテーブルが、信号変換部53に記憶されている。   Specifically, for example, when a PWM signal S having an on-duty value of 99% is input, the signal converter 53 controls the output phase angle to 179 degrees according to the PWM signal S, and the light output of the LED 54 is 98. %become. As with the incandescent lamp luminaire R, a table of output phase angles with respect to the on-duty value of the dimming signal S (PWM signal) is stored in the signal conversion unit 53.

LED照明器具Eに備えられる回線短絡装置55の構成も、蛍光灯照明器具Fa、Fbに備えられた回線短絡装置36と同一であり説明を省略するが、LED照明器具Eに備えられる回線短絡装置55の抵抗の抵抗値Reは、蛍光灯照明器具Fa、Fbに備えられた回線短絡装置36の抵抗の抵抗値Rf、及び白熱灯照明器具Rに備えられた回線短絡装置45の抵抗の抵抗値Rrとは異なった値に設定される。   The configuration of the line short-circuiting device 55 provided in the LED lighting fixture E is also the same as that of the line short-circuiting device 36 provided in the fluorescent lamp lighting fixtures Fa and Fb, and the description thereof will be omitted, but the line short-circuiting device provided in the LED lighting fixture E is omitted. The resistance value Re of the resistance 55 is the resistance value Rf of the resistance of the line short-circuit device 36 provided in the fluorescent lamp luminaires Fa and Fb, and the resistance value of the resistance of the line short-circuit device 45 provided in the incandescent lamp luminaire R. A value different from Rr is set.

従って、調光制御装置2の電源がオンされた直後に、調光制御装置2が調光信号回線L4にオンデューティ値100%の調光信号S(PWM信号)を送信したとき、調光信号回線L4が所定時間tdだけ短絡され、Ie=(Ev÷Re)の短絡電流が流れる。   Accordingly, when the dimming control device 2 transmits a dimming signal S (PWM signal) having an on-duty value of 100% to the dimming signal line L4 immediately after the power of the dimming control device 2 is turned on, the dimming signal The line L4 is short-circuited for a predetermined time td, and a short-circuit current of Ie = (Ev ÷ Re) flows.

次に、各調光信号回線L1、L2、L3、L4に複数の照明器具が接続される構成について、図11(a)、(b)を参照して説明する。3台の蛍光灯照明器具Fa1、Fa2、Fa3が調光信号回線L1に接続された構成が図11(a)に示される。各蛍光灯照明器具Fa1、Fa2、Fa3は、調光信号回線L1に対して回線短絡装置36が並列になるように接続される。このように接続した場合には、調光信号回線L1に調光制御装置2から電圧Evで100%オンデューティ値の調光信号Sが送信されるときに、調光信号回線L1には3×Ifの短絡電流が流れる。   Next, a configuration in which a plurality of lighting fixtures are connected to each dimming signal line L1, L2, L3, L4 will be described with reference to FIGS. 11 (a) and 11 (b). A configuration in which three fluorescent lamp luminaires Fa1, Fa2, and Fa3 are connected to the dimming signal line L1 is shown in FIG. Each fluorescent lamp luminaire Fa1, Fa2, Fa3 is connected so that the line short circuit device 36 is in parallel with the dimming signal line L1. In such a connection, when the dimming signal S having a 100% on-duty value is transmitted from the dimming control device 2 to the dimming signal line L1 at the voltage Ev, the dimming signal line L1 has 3 × If short circuit current flows.

他の調光信号回線L2、L3、L4に対する各照明器具Fb、R、Eの接続構成も、上記の構成と同一であるが、白熱灯照明器具Rについて複数本の白熱灯44を共通の信号変換部43に接続する構成が可能であり、その場合共通の信号変換部43に並列に回線短絡装置45を接続することができる。   The connection configuration of each of the lighting fixtures Fb, R, and E to the other dimming signal lines L2, L3, and L4 is the same as that described above, but a plurality of incandescent lamps 44 are shared by the incandescent lamp lighting fixture R. A configuration for connecting to the conversion unit 43 is possible, and in this case, the line short-circuit device 45 can be connected to the common signal conversion unit 43 in parallel.

具体的には、図11(b)に示されるように、調光信号回線L3に対して1つの回線短絡装置45と1つの信号変換部43が並列に接続され、信号変換部43からの出力線に白熱灯44が並列に接続される。このように接続した場合には、調光信号回線L3に調光制御装置2から電圧Evで100%オンデューティ値の調光信号Sが送信されるときに、調光信号回線L3にはIrの短絡電流が流れる。LED照明器具Eについても、上記のような信号変換部53と回線短絡装置55を共通に接続する構成を採用することも可能である。   Specifically, as shown in FIG. 11B, one line short-circuit device 45 and one signal conversion unit 43 are connected in parallel to the dimming signal line L3, and the output from the signal conversion unit 43 is output. An incandescent lamp 44 is connected in parallel to the line. In this case, when a dimming signal S having a 100% on-duty value is transmitted from the dimming control device 2 to the dimming signal line L3 at the voltage Ev, the dimming signal line L3 has Ir. Short circuit current flows. The LED lighting fixture E can also employ a configuration in which the signal conversion unit 53 and the line short circuit device 55 are connected in common.

次に、本実施形態の調光制御システム1の調光制御動作について説明する。調光制御装置2の電源回路22がオンされ、続いて各照明端末Fa、Fb、R、Eの電源回路32、42、52がオンされる(図7参照)。調光制御装置2のマイクロプロセッサ23は、電源がオンされた直後に、各調光信号回線L1、L2、L3、L4の調光信号出力回路24に対してオンデューティ値100%の調光信号Sを出力する指令信号を出力し、各調光信号出力回路24は、オンデューティ値100%の調光信号Sを出力する。   Next, the dimming control operation of the dimming control system 1 of the present embodiment will be described. The power supply circuit 22 of the dimming control device 2 is turned on, and then the power supply circuits 32, 42, 52 of the respective lighting terminals Fa, Fb, R, E are turned on (see FIG. 7). The microprocessor 23 of the dimming control device 2 immediately after the power is turned on, the dimming signal having an on-duty value of 100% to the dimming signal output circuits 24 of the dimming signal lines L1, L2, L3, and L4. A command signal for outputting S is output, and each dimming signal output circuit 24 outputs a dimming signal S having an on-duty value of 100%.

各照明端末Fa、Fb、R、Eの回線短絡装置36、45、55は、タイマ回路39がオンする所定時間tdだけ、各調光信号回線L1、L2、L3、L4を短絡し、各調光信号回線L1、L2、L3、L4にそれぞれ異なった値の短絡電流を生じさせる。   The line short-circuit devices 36, 45, 55 of the respective lighting terminals Fa, Fb, R, E short-circuit the dimming signal lines L1, L2, L3, L4 for a predetermined time td when the timer circuit 39 is turned on. Different values of short-circuit current are generated in the optical signal lines L1, L2, L3, and L4.

各調光信号回線L1、L2、L3、L4の短絡時間tdは、短い時間に設定され、調光制御装置2が各照明端末の種別を判定した後、各照明端末に対して所定のオンデューティ値の調光信号Sを送信するときに、その調光信号Sを短絡してしまうことがない。また、調光制御装置2がオンデューティ値100%の調光信号Sを出力する時間も短い時間に設定されている。   The short circuit time td of each dimming signal line L1, L2, L3, L4 is set to a short time, and after the dimming control device 2 determines the type of each lighting terminal, a predetermined on-duty is applied to each lighting terminal. When the value dimming signal S is transmitted, the dimming signal S is not short-circuited. In addition, the time during which the dimming control device 2 outputs the dimming signal S having an on-duty value of 100% is also set to a short time.

調光信号回線L1にn台の蛍光灯照明器具Fa1、Fa2・・Fanが接続されている場合には、調光信号回線L1に短絡電流n×Ifが流れ、調光信号回線L2にn台の蛍光灯照明器具Fb1、Fb2・・Fbnが接続されている場合には、調光信号回線L2に短絡電流n×Ifが流れ、調光信号回線L3にn台の白熱灯照明器具R1、R2・・Rnが、図11(b)に示されるような信号変換部43を共通化する構造を採らずに接続されている場合には、調光信号回線L3に短絡電流n×Irが流れ、調光信号回線L4にn台のLED照明器具E1、E2・・Enが、図11(b)に示されるような信号変換部53を共通化する構造を採らずに接続されている場合には、調光信号回線L4に短絡電流n×Ieが流れる。   When n fluorescent lamp luminaires Fa1, Fa2,... Fan are connected to the dimming signal line L1, a short-circuit current n × If flows through the dimming signal line L1, and n units are connected to the dimming signal line L2. When the fluorescent lamp lighting fixtures Fb1, Fb2,... Fbn are connected, a short-circuit current n × If flows through the dimming signal line L2, and n incandescent lamp lighting fixtures R1, R2 flow through the dimming signal line L3. When Rn is connected without adopting a structure that shares the signal conversion unit 43 as shown in FIG. 11B, a short-circuit current n × Ir flows through the dimming signal line L3. When n LED lighting fixtures E1, E2,... En are connected to the dimming signal line L4 without adopting a structure for sharing the signal conversion unit 53 as shown in FIG. The short-circuit current n × Ie flows through the dimming signal line L4.

各調光信号回線L1、L2、L3、L4に流れる短絡電流n×If、n×If、n×Ir、n×Ieは、調光制御装置2の短絡電流値測定回路25によって測定され、各短絡電流値測定回路25は、測定値をマイクロプロセッサ23へ送信する。   The short-circuit currents n × If, n × If, n × Ir, and n × Ie flowing through the dimming signal lines L1, L2, L3, and L4 are measured by the short-circuit current value measuring circuit 25 of the dimming control device 2, The short-circuit current value measurement circuit 25 transmits the measurement value to the microprocessor 23.

マイクロプロセッサ23は、各調光信号回線L1、L2、L3、L4の短絡電流値測定回路25から受信した各測定値について、予め記憶部26内に記憶してある照明端末の種別に応じた短絡電流の値の整数倍であるか否かを判断し、整数倍である場合には、各調光信号回線L1、L2、L3、L4に接続された照明端末の種別を判定し、整数倍でない場合には、当該調光信号回線において種別の異なる照明端末が接続されているとしてアラーム等の報知手段を動作させてユーザに異常を報知する。   The microprocessor 23 short-circuits each measured value received from the short-circuit current value measuring circuit 25 of each dimming signal line L1, L2, L3, L4 according to the type of lighting terminal stored in the storage unit 26 in advance. It is determined whether or not the current value is an integral multiple. If it is an integral multiple, the type of the lighting terminal connected to each of the dimming signal lines L1, L2, L3, and L4 is determined, and is not an integral multiple. In such a case, it is assumed that different types of lighting terminals are connected in the dimming signal line, and an alarm or other notification means is operated to notify the user of the abnormality.

具体的には、記憶部26内に蛍光灯照明器具Fa、Fbに対応する短絡電流値としてIfが予め記憶され、白熱灯照明器具Rに対応する短絡電流値としてIrが予め記憶され、LED照明器具Eに対応する短絡電流値としてIeが予め記憶されており、マイクロプロセッサ23は、各短絡電流値測定回路25から受信した各測定値n×If、n×If、n×Ir、n×Ieを上記短絡電流値と比較して整数倍か否かを判断する。整数倍でない場合の態様については後述する。   Specifically, If is previously stored in the storage unit 26 as a short circuit current value corresponding to the fluorescent lamp luminaires Fa and Fb, Ir is stored in advance as a short circuit current value corresponding to the incandescent lamp luminaire R, and LED illumination Ie is stored in advance as a short-circuit current value corresponding to the instrument E, and the microprocessor 23 receives each measurement value n × If, n × If, n × Ir, n × Ie received from each short-circuit current value measurement circuit 25. Is compared with the short-circuit current value to determine whether it is an integral multiple. A mode in the case of not being an integral multiple will be described later.

マイクロプロセッサ23は、各短絡電流値測定回路25から受信した測定値が、それぞれ何れかの照明端末に対応する短絡電流値の整数倍である(上記の例では、n倍)と判断した後、各測定値について何れの照明端末に対応する短絡電流値の整数倍であるかに基づいて、各調光信号回線L1、L2、L3、L4に接続された照明端末の種別を判定する。   After determining that the measurement value received from each short-circuit current value measurement circuit 25 is an integral multiple of the short-circuit current value corresponding to any one of the lighting terminals (in the above example, n times), The type of the lighting terminal connected to each dimming signal line L1, L2, L3, L4 is determined based on the integral value of the short-circuit current value corresponding to which lighting terminal for each measured value.

具体的には、マイクロプロセッサ23は、調光信号回線L1について短絡電流の測定値がn×Ifであるので、蛍光灯照明器具Faが接続されていると判定し、同様にして、調光信号回線L2については、蛍光灯照明器具Fbが接続されており、調光信号回線L3については、白熱灯照明器具Rが接続され、調光信号回線L4については、LED照明器具Eが接続されていると判定する。   Specifically, since the measured value of the short-circuit current for the dimming signal line L1 is n × If, the microprocessor 23 determines that the fluorescent lamp luminaire Fa is connected, and similarly, the dimming signal A fluorescent lamp luminaire Fb is connected to the line L2, an incandescent lamp luminaire R is connected to the dimming signal line L3, and an LED luminaire E is connected to the dimming signal line L4. Is determined.

そして、マイクロプロセッサ23は、判定した各調光信号回線L1、L2、L3、L4に接続されている照明端末の種別を記憶部26に記憶し、ユーザがリモコン3を操作して何れかの照明端末のグループ(オフィス内の何れかの領域)の明るさを調整するときに、マイクロプロセッサ23は、調整すべき調光信号回線L1、L2、L3、L4の照明端末の種別を記憶部26から読出し、さらに読出した照明端末についてのオンデューティ値に対応する光出力値の関係(調光制御情報)を記憶部26から読出し、読出したオンデューティ値に対応する光出力値の関係に基づいて調整すべき調光信号回線の調光信号出力回路24へ所定のオンデューティ値で調光信号Sを出力するように制御する。   Then, the microprocessor 23 stores the type of the lighting terminal connected to each of the determined dimming signal lines L1, L2, L3, and L4 in the storage unit 26, and the user operates the remote controller 3 to select any one of the lighting terminals. When adjusting the brightness of a group of terminals (any area in the office), the microprocessor 23 determines from the storage unit 26 the types of lighting terminals of the dimming signal lines L1, L2, L3, and L4 to be adjusted. Read and further read out the relationship (dimming control information) of the light output value corresponding to the on-duty value for the lighting terminal read from the storage unit 26 and adjust based on the relationship of the light output value corresponding to the read on-duty value Control is performed so that the dimming signal S is output to the dimming signal output circuit 24 of the dimming signal line to be output at a predetermined on-duty value.

例えば、ユーザがリモコン3を操作して調光信号回線L1に接続された蛍光灯照明器具Faの光出力の指示指令(例えば、17%の光出力)を入力したときには、マイクロプロセッサ23は、記憶部26から調光信号回線L1に接続された照明端末が蛍光灯照明器具Faであるという情報を読出し、記憶部26から調光制御情報(図4参照)の蛍光灯照明器具に関するオンデューティ値に対応した光出力値の関係情報を読出し、その関係情報に基づいてユーザが入力した光出力(17%)に対応するオンデューティ値(85%)を決定し、調光信号出力回路24をオンデューティ値85%の調光信号を出力するように制御する。   For example, when the user operates the remote controller 3 to input a light output instruction command (for example, 17% light output) of the fluorescent lamp luminaire Fa connected to the dimming signal line L1, the microprocessor 23 stores The information that the lighting terminal connected to the dimming signal line L1 is the fluorescent lamp luminaire Fa is read from the unit 26, and the on-duty value related to the fluorescent lamp luminaire of the dimming control information (see FIG. 4) is read from the storage unit 26. The relation information of the corresponding light output value is read out, the on-duty value (85%) corresponding to the light output (17%) input by the user is determined based on the relation information, and the dimming signal output circuit 24 is turned on. Control is performed to output a dimming signal having a value of 85%.

調光信号出力回路24は、調光信号回線L1に対してオンデューティ値85%の調光信号Sを出力し、調光信号回線L1に接続された全ての蛍光灯照明器具Fa1、Fa2・・Fanが光出力17%で点灯する。   The dimming signal output circuit 24 outputs a dimming signal S having an on-duty value of 85% to the dimming signal line L1, and all the fluorescent lamp luminaires Fa1, Fa2,... Connected to the dimming signal line L1. Fan lights up with a light output of 17%.

ユーザがリモコン3を操作して他の調光信号回線L2、L3、L4の照明端末に対して所定の光出力の指示指令を入力した場合も同様に、他の調光信号回線L2、L3、L4に接続された蛍光灯照明器具Fb、白熱灯照明器具R、及びLED照明器具Eが入力された通りの光出力で点灯する。   Similarly, when the user operates the remote controller 3 to input a predetermined light output instruction command to the lighting terminals of the other dimming signal lines L2, L3, and L4, the other dimming signal lines L2, L3, The fluorescent lamp luminaire Fb, the incandescent lamp luminaire R, and the LED luminaire E connected to L4 are lit with the light output as input.

なお、記憶部26にシーンごとの各照明端末Fa、Fb、R、Eの光出力が記憶されている場合は、リモコン3からの操作によってシーンを選択することによって、各調光信号回線L1、L2、L3、L4の照明端末Fa、Fb、R、Eの光出力を一括して調整することができる。   In addition, when the light output of each lighting terminal Fa, Fb, R, E for every scene is memorize | stored in the memory | storage part 26, by selecting a scene by operation from the remote control 3, each dimming signal line L1, The light outputs of the lighting terminals Fa, Fb, R, and E of L2, L3, and L4 can be adjusted collectively.

例えば、記憶部26に、図12に示されるようにシーン1乃至シーン3における各照明端末の光出力が記憶されている場合、ユーザがリモコン3を操作してシーン1を選択したときには、調光信号回線L1、L2に接続された蛍光灯照明器具Fa、Fbが光出力50%で点灯され、調光信号回線L3に接続された白熱灯照明器具Rが光出力100%で点灯され、調光信号回線L4に接続されたLED照明器具Eが光出力50%で点灯される。   For example, when the light output of each lighting terminal in the scenes 1 to 3 is stored in the storage unit 26 as shown in FIG. 12, the dimming is performed when the user selects the scene 1 by operating the remote controller 3. The fluorescent lamp luminaires Fa and Fb connected to the signal lines L1 and L2 are turned on with a light output of 50%, and the incandescent lamp luminaire R connected to the dimming signal line L3 is turned on with a light output of 100% and dimmed. The LED lighting device E connected to the signal line L4 is turned on with a light output of 50%.

次に、各調光信号回線L1、L2、L3、L4について、1回線内において種別の異なる照明端末が接続された場合について、図13及び図14を参照して説明する。   Next, with respect to each dimming signal line L1, L2, L3, L4, a case where different types of lighting terminals are connected in one line will be described with reference to FIG. 13 and FIG.

各調光信号回線L1、L2、L3、L4に多数の照明端末が接続されるときには、配線時の手違いにより1つの調光信号回線に異種の照明端末が接続されてしまうことがある。   When a large number of lighting terminals are connected to each of the dimming signal lines L1, L2, L3, and L4, different lighting terminals may be connected to one dimming signal line due to a mistake in wiring.

例えば、図13に示されるように、同一の調光信号回線L1に蛍光灯照明器具Fa1、Fa2と異種の蛍光灯照明器具R1が接続された場合には、調光制御装置2の電源がオンされた直後に調光信号出力回路24から100%オンデューティ値の調光信号S(PWM信号)が電圧Evで出力されたときに、調光信号回線L1に短絡電流(2×If+Ir)が流れ、短絡電流値測定回路25は、その短絡電流値を測定する。マイクロプロセッサ23は、記憶部26に記憶された各照明端末に対応する短絡電流値If、Ir、Ieと比較して短絡電流(2×If+Ir)がそれらの整数倍ではないことを判定してアラームを動作させる。   For example, as shown in FIG. 13, when fluorescent lamp luminaires Fa1 and Fa2 and a different type of fluorescent lamp luminaire R1 are connected to the same dimming signal line L1, the dimming control device 2 is turned on. When a dimming signal S (PWM signal) having a 100% on-duty value is output from the dimming signal output circuit 24 at the voltage Ev immediately after being turned on, a short-circuit current (2 × If + Ir) flows through the dimming signal line L1. The short circuit current value measuring circuit 25 measures the short circuit current value. The microprocessor 23 determines that the short-circuit current (2 × If + Ir) is not an integral multiple of the short-circuit current values If, Ir, and Ie corresponding to each lighting terminal stored in the storage unit 26, and alarms. To work.

アラームの音声や表示には、異常が検出された調光信号回線L1、L2、L3、L4を示す回線番号等の情報を付加することができ、ユーザは、アラームによって配線の間違い等の異常に気づき、示された調光信号回線の配線の修正を行うことができる。   Information such as the line number indicating the dimming signal lines L1, L2, L3, and L4 in which an abnormality has been detected can be added to the alarm sound and display, and the user can make an error such as a wiring error by the alarm. Recognizing and correcting the indicated dimming signal line can be performed.

同一の調光信号回線L3に信号変換部43と回線短絡装置36を共通化して複数の白熱灯照明器具Rを接続する構成において、白熱灯44とは異種の蛍光灯照明器具Faが間違えて接続された場合にも、異常を検出することができる。   In a configuration in which a plurality of incandescent lamp luminaires R are connected to the same dimming signal line L3 by sharing the signal converter 43 and the line short circuit device 36, a fluorescent lamp luminaire Fa different from the incandescent lamp 44 is connected by mistake. In this case, an abnormality can be detected.

例えば、図14に示されるように、同一の調光信号回線L3に白熱灯照明器具Rと蛍光灯照明器具Faが接続された場合には、調光制御装置2の電源がオンされた直後に調光信号出力回路24から100%オンデューティ値の調光信号S(PWM信号)が電圧Evで出力されたときに、調光信号回線L3に短絡電流(Ir+If)が流れ、マイクロプロセッサ23は、記憶部26に記憶された各照明端末に対応する短絡電流値If、Ir、Ieと比較して短絡電流(Ir+If)がそれらの整数倍ではないことを判定してアラームを動作させる。   For example, as shown in FIG. 14, when the incandescent lamp luminaire R and the fluorescent lamp luminaire Fa are connected to the same dimming signal line L3, immediately after the dimming control device 2 is turned on. When a dimming signal S (PWM signal) having a 100% on-duty value is output from the dimming signal output circuit 24 at the voltage Ev, a short-circuit current (Ir + If) flows through the dimming signal line L3, and the microprocessor 23 The alarm is activated by determining that the short circuit current (Ir + If) is not an integral multiple of the short circuit current values If, Ir, and Ie corresponding to each lighting terminal stored in the storage unit 26.

以上のように、本実施形態の調光制御システム1においては、調光制御装置2の短絡電流値測定回路25が各調光信号回線L1、L2、L3、L4に生じる短絡電流を測定し、マイクロプロセッサ23が測定した電流値に基づいて各調光信号回線L1、L2、L3、L4に接続された照明端末の種別を判定するので、各調光信号回線L1、L2、L3、L4に接続された照明端末の種別をより正しく判定することができ、各調光信号回線L1、L2、L3、L4に複数の照明端末が接続される場合に、該複数の照明端末が同一の種別であるか否かを検出することができる。   As described above, in the dimming control system 1 of the present embodiment, the short-circuit current value measuring circuit 25 of the dimming control device 2 measures the short-circuit current generated in each dimming signal line L1, L2, L3, L4. Since the type of the lighting terminal connected to each dimming signal line L1, L2, L3, L4 is determined based on the current value measured by the microprocessor 23, it is connected to each dimming signal line L1, L2, L3, L4.
