Description

本発明は、調光装置に関するものである。 The present invention relates to a light control device.

従来から、2線式の信号線を介して照明装置に接続される調光装置が提供されている(例えば、特許文献1参照)。 Conventionally, two-wire dimmer which is connected to the lighting device through the signal line is provided (e.g., see Patent Document 1).

照明装置は、信号線を介して調光装置から送信される調光信号に応じた光出力で光源を点灯させる。 Illumination device, the light source is lit with a light output corresponding to the dimming signal transmitted from the light control device through a signal line. 光源として発光ダイオードや蛍光灯が用いられる場合には調光信号としてPWM信号が用いられ、光源として白熱灯が用いられる場合には調光信号として位相信号が用いられることが多い。 PWM signal is used as the dimming signal when the light-emitting diode or a fluorescent lamp is used as the light source, the phase signal as the dimming signal is often used when the incandescent lamp is used as the light source. また、調光信号としてPWM信号が用いられる場合であっても、その調光信号が入力されたときの光出力の定格点灯時の光出力に対する比(以下、「調光比」と呼ぶ)とPWM信号のデューティ比との関係は、例えば図5に示すように光源が白熱灯であれば直線Aのようになり、光源が蛍光灯であれば直線Bのようになり、光源が発光ダイオードであれば曲線Cのようになるといったように、光源の種類によって異なる。 Further, even when the PWM signal is used as the dimming signal, the ratio of light output at the time of rated lighting of the light output when the dimming signal is input (hereinafter, referred to as "dimming ratio") and relationship between the duty ratio of the PWM signal, for example, a light source as shown in FIG. 5 would be a straight line a if incandescent lamp, the light source becomes like a line B if the fluorescent lamp, the light source is a light emitting diode as such becomes a curve C if, depends on the type of light source.

そこで、用いる光源が互いに異なる複数種類の照明装置を用いる場合には、図6に示すように、各照明装置3をそれぞれ用いられる調光信号が互いに共通な照明装置3のみからなる複数個(図6では4個)のグループにグループ分けするとともに、照明装置3のグループ毎に別々の信号線2を介して調光装置1に接続していた。 Therefore, when the light source is used different kinds of lighting devices to each other using, as shown in FIG. 6, a plurality (diagram dimming signal used lighting devices 3 each consisting of only the common illumination device 3 with each other with grouped into groups of six four in), it was connected to the dimmer 1 via separate signal lines 2 for each group of lighting devices 3. 各照明装置3はそれぞれ信号線2に例えばマルチドロップ接続される。 Each lighting device 3 is the signal line 2 respectively, for example multi-drop connection. すなわち、共通の信号線2に接続された(つまり、同じグループに属する)全ての照明装置3は一括して制御されるのであって、照明装置3の制御はグループ単位で行われ、グループ毎に互いに独立した制御が可能である。 That is, connected to a common signal line 2 (i.e., the same belonging to the group) all of the illumination device 3 is a of being collectively controlled, control of the illumination device 3 is carried out on a group basis, for each group it is possible independent control each other. 照明装置3は、グループ毎に異なる領域Z1〜Z4に配置されることが多い。 The illumination device 3 are often located in different regions Z1~Z4 for each group.

従来は、信号線2に接続された照明装置3の種別に応じた調光信号を送信するように調光装置1に設定する作業を、信号線2毎に予め行っておく必要があった。 Conventionally, the task of setting the dimming signal corresponding to the type of the illumination device 3 connected to the signal line 2 to the dimmer 1 to transmit, it is necessary to previously performed every signal line 2. しかし、設定を誤っていれば、照明装置3を意図された光出力で点灯させることができない。 However, if incorrectly set, it is impossible to turn on the illumination device 3 at the intended light output. 照明装置3が意図された光出力で点灯しない場合、その原因としては上記設定の誤り又は照明装置3の誤接続の他、照明装置3の故障も考えられるが、従来は、上記のいずれが原因か特定することが難しく、対処に時間がかかることがあった。 If the lighting device 3 does not light at the intended light output, other misconnection error or the illumination device 3 of the above configuration as the cause, but also considered a failure of the lighting device 3, conventionally, one cause of the it is difficult to identify whether there was time may be required to deal with.

以下、本発明を実施するための最良の形態について、図面を参照しながら説明する。 Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

本実施形態は、図1に示すように、外部からの指令が入力される入力部11と、それぞれ信号線2を介して照明装置3に接続される複数個の通信部12と、例えばEEPROMのような不揮発性メモリからなり照明装置3の制御に用いられるデータが格納される記憶部13と、入力部11に入力された指令と記憶部13に格納されたデータとに基づいて信号線2毎に調光信号を生成するとともに生成した調光信号を該信号線2に接続された通信部12を制御して送信させる制御部14と、例えば液晶パネルからなり制御部14に制御されて各種の状態を表示する通知部としての表示部15とを備える。 This embodiment, as shown in FIG. 1, an input unit 11 for a command from the outside is input, a plurality of the communication unit 12 connected to the illumination device 3 via the respective signal line 2, for example of the EEPROM such a storage unit 13 in which data is stored for use in the control of the illumination device 3 a nonvolatile memory, based on the stored input to the input unit 11 the command and the storage unit 13 every data signal line 2 a control unit 14 for a dimming signal generated to generate a dimming signal sent to control signal lines 2 communication unit 12 connected to, for example, is controlled by the control unit 14 a liquid crystal panel various and a display unit 15 as a notification unit for displaying the status.

入力部11は、例えば赤外光を受光するフォトダイオードを有して赤外光を媒体としたワイヤレス信号により指令が入力されるものであってもよいし、操作入力を受け付ける押釦やロータリスイッチ等の入力手段を有して操作入力によって指令が入力されるものであってもよい。 Input unit 11, for example a photodiode for receiving the infrared light may be those instruction is input by the wireless signal as a medium infrared light, a push button or a rotary switch or the like for receiving an operation input input means may be those command is input by a by operating enter.

記憶部13には、入力部11に入力される指令と調光比との対応関係を示すテーブル、並びに、調光比と生成すべき調光信号との対応関係を示すテーブルが格納されている。 The storage unit 13, a table indicating a correspondence relationship between the command and the dimming ratio input to the input unit 11, and a table showing the correspondence between the dimming ratio and the dimming signal to be generated is stored . 1個の指令に対して実行される制御としては、1本の信号線2に対してのみ調光信号を送信する個別制御の他、該指令に対して信号線2毎に予め設定された調光比を指示する調光信号を各信号線2にそれぞれ送信するシーン制御がある。 The control performed for one instruction, other individual control of transmitting only light control signal with respect to one signal line 2, preset tone for each signal line 2 with respect to the finger Ordinance there is a scene control to transmit respectively the dimming signal for instructing the light ratios to each signal line 2.

信号線2は、グランドに接続される接地側線21(図3参照)と、接地側線21に対して調光信号に応じた電圧が加えられる電圧側線22(図3参照)とからなる。 Signal line 2 is composed of a ground side line 21 (see FIG. 3) which is connected to ground, the voltage side line 22 the voltage corresponding to the dimming signal to the ground side line 21 is added (see FIG. 3). 調光信号は、例えばPWM信号である。 Dimming signal is, for example, PWM signal.

照明装置3は、図2に示すように光源4を点灯させる点灯部31を備える。 Illumination device 3 includes a lighting unit 31 for lighting the light source 4 as shown in FIG. 光源4は例えば白熱灯や蛍光灯や発光ダイオードであり、点灯部31は例えば商用電源から供給された交流電力を光源4を点灯させるための電力に変換するものである。 Light source 4 is, for example, incandescent and fluorescent lamps and light emitting diodes, the lighting unit 31 is to convert the electric power for lighting the light source 4 to AC power supplied from, for example, a commercial power supply. このような光源4や点灯部31は周知技術で実現可能であるので、図示並びに詳細な説明は省略する。 Since such a light source 4 and the lighting unit 31 can be realized by a well known technique, illustration and detailed description thereof will be omitted.

また、照明装置3は、信号線2を構成する接地側線21と電圧側線22との間に接続された例えばトランジスタのような半導体スイッチからなる短絡部32と、例えばEEPROMのような不揮発性メモリからなる記憶部33と、記憶部33に予め格納された短絡データに基づいて短絡部32をオンオフ制御する短絡制御部34とを備える。 The illumination device 3 includes a short-circuit portion 32 consisting of a semiconductor switch such as a connected e.g. transistor between ground side line 21 and the voltage side line 22 constituting the signal line 2, for example, from the nonvolatile memory such as an EEPROM It becomes a storage unit 33, and a short circuit control unit 34 for turning on and off the short-circuit unit 32 based on the pre-stored short data in the storage unit 33. 具体的には例えば短絡データは短絡部32をオンする時間(以下、「短絡時間」と呼ぶ。)であって、短絡制御部34は照明装置3の電源が投入されてから短絡時間が経過するまで短絡部32をオンして信号線2を短絡し、短絡時間の経過後に短絡部32をオフする。 Specifically, for example, short data time for turning on the short circuit portion 32 a (hereinafter, referred to as "short time".), Short circuit control unit 34 elapses short time since the power supply of the illumination device 3 is turned on until short-circuited signal line 2 turns on the short circuit portion 32 turns off the short-circuit unit 32 after a short time.

さらに、調光装置1の各通信部12は、それぞれ、図3に示すように、電圧側線22に接続されて調光信号を送信する送信部12aに加え、接地側線21に接続されて信号線2の短絡を検出する短絡検出部12bを備える。 Furthermore, the communication unit 12 of the light control device 1, respectively, as shown in FIG. 3, in addition to the transmission portion 12a transmits the connected dimming signal to the voltage side line 22, the signal line is connected to a ground side line 21 It includes a short circuit detecting section 12b for detecting the second short-circuit.

送信部12aは、定電圧源V1と電圧側線22との間に接続された例えばPNP型のトランジスタからなるスイッチング素子Q1と、制御部14によって制御されてスイッチング素子Q1をオンオフ駆動するドライブ回路12cとを備える。 Transmission unit 12a includes a switching element Q1 consisting of connected e.g. PNP type transistor between the constant voltage source V1 and the voltage side line 22, a drive circuit 12c that is controlled by a control unit 14 for on-off driving the switching elements Q1 equipped with a.

短絡検出部12bは、ベースがダイオードD1を介して接地側線21に接続されるとともにエミッタがグランドに接続されコレクタが抵抗R1を介して制御部14に接続されたNPN型のトランジスタQ2を備える。 Short-circuit detector 12b is provided with a base of an NPN type having a collector emitter connected to ground is connected to the control unit 14 via a resistor R1 is connected to the ground side line 21 via the diode D1 transistor Q2. 抵抗R1とトランジスタQ2との接続点は、抵抗R2を介して定電圧源V2に接続されている。 Connection point between the resistor R1 and the transistor Q2 is connected to a constant voltage source V2 through a resistor R2. すなわち、信号線2に短絡が生じている期間に送信部12aの出力がHレベルとなると、トランジスタQ2がオンされ、短絡検出部12bの出力はLレベルとなる。 That is, when the output of the transmission unit 12a during a short circuit in the signal line 2 is generated becomes H level, the transistor Q2 is turned on, the output of the short circuit detector 12b has an L level. これに対し、信号線2に短絡が生じていない、又は、信号線2に短絡が生じていても送信部12aの出力がLレベルであるときには、トランジスタQ2はオフされ、短絡検出部12bの出力はHレベルとなる。 In contrast, short-circuited to the signal line 2 has not occurred, or, even if short-circuited to the signal line 2 has not occurred when the output of the transmission unit 12a is at the L level, the transistor Q2 is turned off, the output of the short circuit detector 12b becomes the H level.

制御部14は、少なくとも調光信号がHレベルとなる期間には短絡検出部12bの出力を監視しており、図4に示すように、いずれかの信号線2において短絡検出部12bによって短絡が検出されたとき(すなわち、短絡検出部12bの出力がLレベルとなったとき)には、その信号線2に関して、調光信号を出力する通常動作から、調光信号を出力せず短絡の継続時間を計時する検出動作に移行する。 Control unit 14, the period in which at least the dimming signal becomes the H level monitors the output of the short circuit detector 12b, as shown in FIG. 4, it is shorted by the short circuit detecting unit 12b in any of the signal lines 2 when detected (i.e., when the output of the short circuit detector 12b becomes L level), with respect to the signal line 2, from the normal operation to output a dimming signal, the continuation of the short circuit does not output a dimming signal to migrate to the detection operation for counting a time.

検出動作においては、通常動作において調光信号を送信していたタイミングで送信部12aを制御して調光信号よりも短時間だけ送信部12aの出力をHレベルとし、この間、短絡検出部12bの出力を監視するといった動作を定期的に繰り返し、送信部12aの出力をHレベルとしている間に短絡検出部12bの出力がHレベルのままであれば(つまり短絡時間が終了していれば)、検出動作を終了して通常動作に復帰する。 Detection In operation, the output of the short time transmitting section 12a than the control and dimming signal transmission section 12a at the timing that has transmitted the light control signal in the normal operation to the H level during this period, the short circuit detector 12b periodically repeating the operation such monitoring the output, (if completed that short time) the output of the short circuit detector 12b is equal to or remains at the H level while the output of the transmission unit 12a is set to H level, to end the detection operation to return to normal operation. そして、通常動作に復帰するまでの間、短絡検出部12bの出力がLレベルとなった回数を計数することにより短絡時間を計時する。 Then, until the return to the normal operation, to count a short time by counting the number of times the output of the short circuit detector 12b becomes L level.

ここで、短絡時間は、照明装置3の種別毎に、上記検出動作において計数される回数が異なる程度に短絡時間を異ならせてある。 Here, short time, for each type of illumination device 3, the number of times counted in the detection operation are made different short time to different extents. 例えば、白熱灯を光源とする照明装置3であれば短絡が3回検出され、白色の発光ダイオードを光源とする照明装置3であれば短絡が7回検出され、電球色の発光ダイオードを光源とする照明装置3であれば短絡が10回検出され、RGB型の発光ダイオードを光源とする照明装置3であれば短絡が14回検出されるように、それぞれ短絡時間が設定されている。 For example, the short-circuit detection is three times as long as the incandescent lamp lighting device 3 as a light source, and the detected white light emitting diode lighting device 3 is long if short circuit 7 times as a light source, a light emitting diode bulb color light source short if the illuminating device 3 is detected 10 times for as short if the lighting apparatus 3 to the RGB light-emitting diodes as a light source is detected 14 times, it is set respectively short time. 従って、調光装置1では、検出動作において計数される回数に基づいて、その信号線2に接続された照明装置3の種別を検出することができる。 Accordingly, the light control device 1, based on the number of times that is counted in the detection operation, it is possible to detect the type of the illuminating device 3 connected to the signal line 2.

すなわち、調光装置1の記憶部13には、検出動作において計数される回数と、照明装置3の種別との対応関係が格納されている。 That is, the storage unit 13 of the light control device 1, the number of times counted in the detection operation, the correspondence between the type of the illuminating device 3 is stored. 制御部14は、検出動作の終了時に、検出動作を行った信号線2に接続された照明装置3の種別を上記対応関係に基づいて検出し、結果を表示部15に表示する。 Control unit 14, when the detection operation is completed, the type of the illuminating device 3 connected to the signal line 2 of performing the detecting operation to detect based on the correspondence relationship, and displays on the display section 15 results.

上記構成によれば、信号線2に接続された照明装置3の種別が検出されて表示部15に表示されるから、使用者は表示部15への表示を見て照明装置3の誤接続を知り、例えば照明装置3の交換などの適切な対処を行うことができるから、照明システムの保守性が向上する。 According to the above configuration, the since the type of the illumination device 3 connected to the signal line 2 is displayed on the display unit 15 is detected, the user erroneous lighting device 3 viewing the display on the display unit 15 connected know, for example, because it is possible to perform appropriate measures such as replacement of the lighting device 3, the maintenance of the illumination system is improved.

また、短絡が検出されたときに調光信号の出力が停止され、検出動作中に短絡を検出するために送信部12aから出力される信号のパルス幅(出力がHレベルとなる期間の長さ)が調光信号よりも短いことにより、調光信号の出力が継続される場合に比べて消費電力が低減される。 Moreover, short-circuit is output stop of the dimming signal when it is detected, the length of time the pulse width (output becomes H-level signal output from the transmission section 12a to detect a short circuit during the detection operation ) by less than the dimming signal, the power consumption as compared with the case where the output of the dimming signal is continued is reduced.

なお、通知部は上記のような視覚による通知を行う表示部15に限られず、例えばスピーカーを有し音声を用いて聴覚による通知を行うものを表示部15に代えて又は表示部15とともに用いてもよい。 The notification unit may be used with the display unit 15 in a limited without, or the display unit 15 instead of the display unit 15 to perform notification by audible with audio has for example a speaker to notify visual as described above it may be.

また、照明装置3が短絡動作を行うタイミングは、上記のような電源投入直後に限られず、例えば、時刻を検出する時計部(図示せず)を各照明装置3にそれぞれ設けるとともに、記憶部33に予め格納された所定の時刻に短絡制御部32が短絡動作を開始するようにしてもよい。 The timing of the lighting apparatus 3 performs the short-circuit operation is not limited to immediately after the power-on as described above, for example, a clock unit for detecting a time (not shown) provided with each of the lighting devices 3, the storage unit 33 short circuit control unit 32 in a predetermined time may be started short circuit operation previously stored in.
