Description

【0001】
【発明の属する技術分野】
この発明は、照明制御装置に関するものである。
【0002】
【従来の技術】
照明制御装置は、人の在・不在を検知する人感センサと、下面の反射光量を検知する明るさセンサを具備して、人の在・不在の情報などにより照明器具のランプ出力による下面(床面等)からの反射光を、照明制御装置に設けた明るさセンサで検知し、一定の反射光(明るさセンサ値)になるように、照明器具の調光レべルをフィードバック制御することで、被照射面を一定の明るさに制御などを行う。
【0003】
または、人感センサのみを具備し、人の在・不在の情報などにより照明器具のランプ出力を変化させる。さらに、明るさセンサのみを具備し、ランプ出力による下面からの反射光を、照明制御装置に設けた明るさセンサで検知し、一定の反射光(明るさセンサ値)になるように、照明器具の調光レべルをフィードバック制御することで、被照射面を一定の明るさに制御などを行う。
【0004】
例えば図15に示す照明制御装置は、照明器具100のランプ出力による床面103からの反射光P1 を、調光制御部102に設けた明るさセンサ101で検知し、一定の反射光(明るさセンサ値)になるように、照明器具100の調光レべルをフィードバック制御することで、被照射面(床面103等)を一定の明るさに制御する。この明るさセンサ101の値等はリモコン104によって調整および設定していた。110はリモコン受信部である。
【0005】
このような照明制御装置は図16に示すような回路構成になっている。すなわち、電源基板105は、マイコンや周辺回路、調光信号用の回路、外部連動を行うオープンコレクタ等の回路、センサ等への電源供給を行う各種電源回路が実装されている。制御基板106は、マイコンや周辺回路、調光信号用の回路、外部連動を行うオープンコレクタ等の回路が実装されている。基本機能としては、マイコンでは、センサの信号出力を一定に保つように、調光信号により、照明器具の明るさをフィードバック制御を行う。その他、外部機器との連動も行う。センサ基板107は、明るさセンサ101や人感センサや設定手段としてのリモコン回路やスイッチ等が実装されている。また、明るさセンサのばらつきを調整するためのボリュームも実装されている。
【0006】
このような照明制御装置では、図17(a)に示すような3枚のP板(プリント基板)を立体的に組み立てる構造のものがあった。器具の外観は図17(b)に示す。このP板は、電源基板105と制御基板106とセンサ基板107よりなる。各基板間は信号線L1 、L2 によりコネクタ109を介して接続されている。制御基板106と電源基板105間は、信号線L2 で接続されている。制御基板106とセンサ基板107間は信号線L1 により接続されている。信号線L1 は、主にセンサ信号とセンサ回路の電源、スイッチやリモコンなどの設定回路への入出力と回路への電源等が配線されている。信号線L2 は、電源回路からのマイコンや外部照明器具へ調光信号用電源、センサへの電源等が配線されている。
【0007】
【発明が解決しようとする課題】
図18に示すように器具の構造の展開を行つた場合、すなわち、基板が同一面となるように開いたとき、信号線L1 が長くなり、ノイズ等の影響を受けやすくなる。特に、センサ基板107ヘの電源ラインが延びることになり、誤動作が起きやすくなる。なぜなら、一般的にセンサ基板107は微弱な信号を増幅しており、高インピーダンスでありノイズ等には弱い。
【0008】
また、信号線L2 が伸びることにより、電源信号(信号線L2 )より、ノイズを逆に外に輻射しやすくなる。センサ基板107上に、センサの調整用にボリュームが実装されている場合信号線L2 が邪魔になる。
【0009】
また、このような照明制御装置は、天井面に直接取付けられたり埋め込まれたりする。
【0010】
制御基板106に外部機器との連動用に、外部コネクタ108が実装されており、図17の器具では、外部コネクタ108が天井裏で配線できたが、図18においては、器具の表面(下面)で、配線するようになり、危険で、見栄えもよくないものであつた。
【0011】
従来では、共通の基板で各種器具に適用できるように展開を行うと、構造上やノイズ面で問題となり、従って容易に器具展開ができなかった。
【0012】
したがって、この発明の目的は、共通の基板にて器具展開が容易に行え、かつノイズ等の品質上信頼性の高い照明制御装置を提供することである。
【0013】

請求項7記載の照明制御装置によれば、請求項1または請求項2と同様な効果がある。
【0027】
【発明の実施の形態】
この発明の第1の実施の形態を図1により説明する。図15について説明したように、光源と点灯手段を有する照明器具100のランプ出力による下面(床面103等)からの反射光を、制御装置に設けた調光制御部を構成する明るさセンサ101で検知し、一定の反射光(明るさセンサ値)になるように照明器具100の調光レべルをフィードバック制御することで、被照射面を一定の明るさに制御する。この明るさセンサ101の値等は、リモコン104によつて調整および設定する。この制御装置の調光制御部を備える回路構成は、図16に示す通りである。
【0028】
この実施の形態の照明制御装置は、図1に示すように、3枚の基板で構成されている。基板は、おもに電源基板1と制御基板2とセンサ基板3となっており、センサ基板3は中央に位置している。
【0029】
図1に示すように、制御基板2とセンサ基板3、電源基板1とセンサ基板3は信号線M1 、M2 で結ばれる。センサ回路用の電源は、電源基板1から、信号線M1 を介して、基板上のパターンを通じて、直接供給される。センサ回路用の電源パターンは、センサ基板3で止まる。
【0030】
制御基板2で使われる電源については、センサ基板3上のパターンを通して、信号線M2 を介して、制御基板2へ電源が供給される。
【0031】
その他の信号(センサ出力、リモコン入出力等)については、信号線M2 を介して、センサ基板3と制御基板2間でやり取りが行われる。
【0032】
第1の実施の形態により、センサ回路の電源、その他の電源および信号線が最短で配線されるため、ノイズによる影響を極力おさえることができ、かつ外部に対してのノイズ輻射も極力おさえることができた。例えば直付け器具および埋込器具ともに共用できるようになった。
【0033】
この発明の第2の実施の形態を図2により説明する。すなわち、第1の実施の形態において、制御基板2と電源基板1は、センサ基板3に対して直角(同図(a)の場合)または水平(同図(b)の場合)に可動できるように、屈曲性の高いフラットケーブルや回動可能なコネクタなどの接続手段4で図2のように基板間を接続する。
【0034】
第2の実施の形態により、信号および電源の配線条件を崩すことなく、電源基板1および制御基板2をセンサ基板3に対して、直角や水平に動かすことができ、各種タイプの照明器具に共用でき、器具の展開が容易になった。
【0035】
その他は、第1の実施の形態と同様である。
【0036】
この発明の第3の実施の形態を図3により説明する。すなわち、第2の実施の形態において、制御基板2と電源基板1を同図(a)に示すように、センサ基板3に対して直角にしたとき、センサ基板3の幅A、電源基板1上の部品5の高さBとするとセンサ基板3の長さAを、部品の高さBに対して長くなるように基板の設計を行う。同様に制御基板2上の部品の高さもセンサ基板3の長さAよりも短くしている。さらに制御基板2の部品と電源基板1の部品5とが相互に当たる配置のときは部品同士が衝突しないようにさらに高さが制限される。また部品5の配置に関してはセンサ基板3の部品との衝突を避けるように考慮する。
【0037】
第3の実施の形態により、部品5の再配置や再選定を行うことなく、電源基板1および制御基板2をセンサ基板3に対して直角や同図(b)のように水平に動かすことができ、器具の展開が容易になった。
【0038】
この発明の第4の実施の形態を図4および図5により説明する。第2の実施の形態において、制御基板2に制御信号用コネクタ受け17を設けたものである。コネクタ13は、図4(a)に示すようにコネクタ13の表側に線挿入口10を有し、図(b)に示すようにピン11を示す。このコネクタ13はピン11が千鳥配置になっている。またピン11の配置についてはストレートでも同様である。
【0039】
図4(c)に制御基板2を示す。図4(c)は制御基板2の表面であり、一側にコネクタ受け17が設けてある。図4(d)は表面用の穴、図4(e)は裏面用の穴を示す。制御基板2のコネクタ受け17にコネクタ13のピン11が実装可能な穴があいているが、それぞれ制御基板2の表面・裏面からコネクタ13が実装可能なように、図(d)や図(e)に示すように表面用の穴(黒の表示)と裏面用の穴(点の表示)があけられている。このため、器具の展開によつて基板の表裏いずれかより制御信号用のコネクタ13が実装可能になった。したがって、実施の形態により、図5(a)に示すようにケース12に収納された3つの基板1〜3の折曲状態の制御基板2の裏面側から信号線を挿入したり、図5(b)に示すようにケース12′に収納された3つの基板1〜3の展開状態の制御基板2の表面側から信号線を挿入することができ、器具の種類によらず、信号線を適切な方向から挿入できるようになった。なお、電源基板1にも電源用コネタクを上記のように設けることもできる。
【0040】
この発明の第5の実施の形態を図6および図7により説明する。すなわち、センサ基板3において、図7に示すようにセンサ素子として例えばフォトダイオードPD1等を使用し、微弱な電流をオペアンプOP1、OP2等を用いたI−V変換回路や増幅回路等を組み合わせて信号増幅を行っているが、素子や抵抗のばらつきを抑えるために、可変抵抗のボリューム15等の調整機構で調整を行う必要がある。このボリューム15はノイズ面において、オペアンプの近くに実装される必要がある。したがって、センサ基板3にボリューム15があり、図6(b)に示すように制御基板2と電源基板1をセンサ基板3に対して直角になるようにした場合、ボリュームバーが調整可能なように制御基板2と電源基板1の部品が配置される。
【0041】
この調整を行うのに、図5に示すような器具展開を行った場合、図6(a)の器具の場合は問題ないが、図6(b)の器具ではセンサ基板3の上方に電源基板1の部品5が位置する可能性があり、部品5が邪魔になり、センサ基板3のボリューム15を調整できない。そこで、センサ基板3のサイズを、電源基板1上の部品5の高さ+αのサイズに設定、あるいは高い部品5を避けて、ボリューム15の位置の決定を行うようにする。
【0042】
第5の実施の形態により、器具の展開によらずに、調整が可能になった。
【0043】
この発明の第6の実施の形態を図8から図10により説明する。すなわち、図17のように制御基板2と電源基板1を、センサ基板3に対して直角になるように器具にて位置決めを行う。22は円筒状の器具本体、23は上蓋、24は器具本体22の周壁の孔に引っ掛けるフック24aのあるカバー、25はブッシング、26はフィルタ、27は器具本体22を天井裏に固定するための取付ばね、30電源端子台である。実施の形態の位置決め部は図10に示すように、制御基板2と電源基板1を内周面と内周面の軸方向に形成した突条28、29と、センサ基板3の両側を挟持する一対のばね(図示せず)からなっており、制御基板2と電源基板1を先に突条28、29とそれらに隣接する内周面間に挿入され一対のばねでセンサ基板3を挟持することにより全体が器具内に保持される。センサ基板3と制御基板2および電源基板1は接続手段4として屈曲可能なフラットケーブルの剛性による。
【0044】
この発明の第7の実施の形態を図11から図14により説明する。すなわち、図11において、25は図8と同様なブッシング、26は図8と同様なセンサ感度補正フィルタアクリル、30は図8と同様な電源端子台、32は小カバー、35は大カバー、39は制御ブロックカバー、40は器具本体である。
【0045】
図12において、大カバー35が器具本体40に取付けられ、大カバー35内に制御ブロックカバー39が収納され、その内側に制御ブロックの基板1〜3が収納され、小カバー32が基板1、2に爪33により係止されている。
【0046】
図13に示すように、制御基板2と電源基板1を、センサ基板3に対して水平すなわち略面一になるようにして器具にて位置決めを行う。位置決めは大カバー35の内側に位置した支持壁36の内側面に形成した段部37と、この段部37の上側に設けた係止爪38の間に係止爪38側から基板1〜3の周縁を押し込んで保持している。
【0047】
図14(a)に基板全体の外形図を示す。電源基板1と制御基板2のほぼ真中に孔31が空いている。図14(b)に小カバー32の断面図を示し、周縁部に爪33を形成している。孔31に、小カバー32の爪33を、はめ込み、器具の一部分である、小カバー32を基板1、2で保持する。42はセンサ孔である。
【0048】
第7の実施の形態により、器具の展開によらずにすなわち器具のタイプによらずに、基板を共通にして基板の保持が可能になった。
【0049】
【発明の効果】
請求項1記載の照明制御装置によれば、センサ基板上のセンサ回路の電源、その他の電源や信号線が最短で配線できるためノイズによる影響を極力抑えることができ、かつ外部に対してのノイズ輻射も極力おさえることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a lighting control device.
[0002]
[Prior art]
The lighting control device includes a human sensor that detects the presence / absence of a person and a brightness sensor that detects the amount of reflected light on the lower surface, and the lower surface ( The reflected light from the floor, etc.) is detected by the brightness sensor provided in the lighting control device, and the dimming level of the lighting fixture is feedback controlled so that the reflected light (brightness sensor value) is constant. Thus, the surface to be irradiated is controlled to have a constant brightness.
[0003]
Alternatively, only the human sensor is provided, and the lamp output of the lighting fixture is changed according to the presence / absence information of the person. Furthermore, it has only a brightness sensor, and the reflected light from the lower surface due to the lamp output is detected by the brightness sensor provided in the illumination control device, so that the reflected light (brightness sensor value) becomes constant. By performing feedback control of the light control level, the surface to be irradiated is controlled to have a constant brightness.
[0004]
For example, the illumination control device shown in FIG. 15 detects the reflected light P 1 from the floor surface 103 due to the lamp output of the luminaire 100 by the brightness sensor 101 provided in the dimming control unit 102, and generates a constant reflected light (brightness). Feedback control of the dimming level of the luminaire 100 so that the illuminated surface (floor surface 103, etc.) is controlled to a constant brightness. The value of the brightness sensor 101 is adjusted and set by the remote controller 104. Reference numeral 110 denotes a remote control receiving unit.
[0005]
Such an illumination control device has a circuit configuration as shown in FIG. That is, the power supply board 105 is mounted with a microcomputer, a peripheral circuit, a dimming signal circuit, a circuit such as an open collector that performs external interlocking, and various power supply circuits that supply power to sensors and the like. The control board 106 is mounted with a circuit such as a microcomputer, a peripheral circuit, a dimming signal circuit, and an open collector that performs external interlocking. As a basic function, the microcomputer performs feedback control of the brightness of the luminaire by the dimming signal so as to keep the signal output of the sensor constant. In addition, it works with external devices. The sensor board 107 is mounted with a brightness sensor 101, a human sensor, a remote control circuit as a setting means, a switch, and the like. A volume for adjusting the variation of the brightness sensor is also mounted.
[0006]
Such an illumination control device has a structure in which three P boards (printed boards) as shown in FIG. The appearance of the instrument is shown in FIG. The P plate includes a power supply substrate 105, a control substrate 106, and a sensor substrate 107. Each board is connected via a connector 109 by signal lines L 1 and L 2 . During the control board 106 and the power supply board 105 are connected by a signal line L 2. The control board 106 and the sensor board 107 are connected by a signal line L 1 . The signal line L 1 is mainly wired with a sensor signal and a power source for the sensor circuit, an input / output to a setting circuit such as a switch and a remote controller, a power source for the circuit, and the like. The signal line L 2 is connected with a power source for dimming signals, a power source for sensors, and the like from a power source circuit to a microcomputer and an external lighting fixture.
[0007]
[Problems to be solved by the invention]
When having conducted the development of the structure of the device as shown in FIG. 18, i.e., when the substrate is opened so that the same surface, the longer the signal line L 1, susceptible to noise or the like. In particular, the power supply line to the sensor substrate 107 is extended, and malfunction is likely to occur. This is because, in general, the sensor substrate 107 amplifies a weak signal, has high impedance, and is vulnerable to noise and the like.
[0008]
Further, the extension of the signal line L 2 makes it easier to radiate noise to the outside than the power signal (signal line L 2 ). On the sensor substrate 107, when the signal line L 2 to which the volume is mounted is a hindrance for the adjustment of the sensor.
[0009]
Also, such a lighting control device is directly attached to or embedded in the ceiling surface.
[0010]
An external connector 108 is mounted on the control board 106 for interlocking with an external device. In the instrument of FIG. 17, the external connector 108 can be wired behind the ceiling, but in FIG. And now that it is wired, it is dangerous and not good looking.
[0011]
