Description

本発明は、光源の明るさを調整するとともに累積点灯時間を計時する点灯装置を具備する照明システム及び照明器具に関する。   The present invention relates to a lighting system and a lighting fixture including a lighting device that adjusts brightness of a light source and measures a cumulative lighting time.
従来、放電灯などの光源の明るさを調整可能な点灯装置を内蔵した調光機能付きの照明器具が一般的に普及している。このような調光機能付きの照明器具を複数台用いた照明システムにおいては、照明器具に調光レベルを示す調光信号(アナログ信号又はディジタル信号)を送る調光信号線を敷設し、例えば壁面に取り付けられた調光コントローラから調光信号を各照明器具に伝達することにより、利用者が光源の明るさを任意に調整できるようにした照明システムが一般的である。しかしながら、このような照明システムでは、各照明器具に商用電源を供給するための電源線と、調光信号を伝達する調光信号線との両方を敷設する配線工事が必要であった。また、既設の調光機能を有さない照明器具から調光機能付きの照明器具に置き換える場合には、調光信号線が敷設されていないために対応できないという問題があった。この問題を解決するために、例えばリモコン等による無線での調光信号の伝達技術や、商用電源電圧に調光信号を重畳させる電源線信号搬送技術などが提案されているが、何れにおいても信号の送受信部にコストがかかるため、照明システム全体のコストが増大するという問題があった。   2. Description of the Related Art Conventionally, lighting fixtures with a dimming function that incorporate a lighting device capable of adjusting the brightness of a light source such as a discharge lamp have been widely used. In such a lighting system using a plurality of lighting fixtures with a dimming function, a dimming signal line for sending a dimming signal (analog signal or digital signal) indicating a dimming level to the lighting fixture is laid, for example, a wall surface A lighting system is generally used in which a user can arbitrarily adjust the brightness of a light source by transmitting a dimming signal from a dimming controller attached to the lamp to each lighting fixture. However, in such a lighting system, wiring work for laying both a power line for supplying commercial power to each lighting fixture and a dimming signal line for transmitting a dimming signal is required. In addition, when replacing an existing lighting fixture that does not have a dimming function with a lighting fixture with a dimming function, there is a problem that the dimming signal line is not installed and cannot be handled. In order to solve this problem, for example, a wireless dimming signal transmission technique using a remote control or a power line signal carrier technique for superimposing a dimming signal on a commercial power supply voltage has been proposed. Since there is a cost for the transmission / reception unit, there is a problem that the cost of the entire lighting system increases.
その一方で、例えば住宅用の照明器具においては、電源スイッチ(壁スイッチ)のオン/オフ操作によって光源の明るさを可変する手段が用いられている。これは、例えば特許文献1に記載されているように、電源スイッチがオフされてから再びオンされるまでの操作時間が所定時間内に入るかどうかを照明器具が認識するもので、短時間での電源オフ操作を認識する度に光源の明るさを例えば、全点灯→調光点灯→消灯(常夜灯)→全点灯というように順次切り替える方式が一般的に広く採用されている。   On the other hand, for example, in a residential lighting fixture, means for changing the brightness of a light source by turning on / off a power switch (wall switch) is used. For example, as described in Patent Document 1, the lighting fixture recognizes whether the operation time from when the power switch is turned off to when it is turned on again falls within a predetermined time. In general, a method of sequentially switching the brightness of the light source every time when the power-off operation is recognized, such as all lighting → dimming lighting → extinguishing (nightlight) → all lighting is widely adopted.
他にも、特許文献2によれば、操作者が電源スイッチをオン/オフさせる第1の操作を行うと、放電灯の調光率をそれまで設定していた値から所定の時間間隔で順次暫定的に変化させ、次に操作者が電源スイッチをオン/オフさせる第2の操作を行うと暫定的に順次変化させている調光率のうち、第2の操作時における調光率を以降の調光レベルとして放電灯を点灯できるようにすることが提案されている。このような手段を用いる場合、既設の電源線を利用して利用者が光源の明るさを調整できるため、新たに調光信号線を敷設する必要が無いという利点がある。   In addition, according to Patent Document 2, when the operator performs the first operation to turn on / off the power switch, the dimming rate of the discharge lamp is sequentially set at a predetermined time interval from the value set so far. Temporarily change, and then the dimming rate during the second operation among the dimming rates that are tentatively changed sequentially when the operator performs the second operation to turn on / off the power switch will be described below. It has been proposed that the discharge lamp can be turned on as a dimming level. When such a means is used, the user can adjust the brightness of the light source by using an existing power line, so that there is an advantage that it is not necessary to newly install a dimming signal line.
一方、光源の点灯時間を計時する点灯装置が提案されている。例えば、放電灯などの光源の光束が点灯初期では定格よりも高く、累積点灯時間に応じて減退することを考慮して、光源の累積点灯時間を計時してその累積点灯時間に応じて光束の減退に見合う程度に光源への供給電力を変化させ、累積点灯時間に依らず光出力を定格に保つことで点灯初期から寿命までの余分な電力を抑える点灯装置が広く採用されている。このような点灯装置では、光源を交換する際に累積点灯時間をリセットする必要がある。その手段として、例えば光源の寿命末期や光源の交換を検出し、光源の交換時に累積点灯時間を自動的にリセットするものがある。しかしながら、上記の点灯装置では、例えば掃除や手入れ等で利用者が意図的に光源を外した場合でも累積点灯時間がリセットされてしまう。   On the other hand, a lighting device that measures the lighting time of the light source has been proposed. For example, in consideration of the fact that the luminous flux of a light source such as a discharge lamp is higher than the rated value at the beginning of lighting and declines according to the cumulative lighting time, the cumulative lighting time of the light source is timed and the luminous flux according to the cumulative lighting time is measured. A lighting device is widely adopted that changes the power supplied to the light source to an extent suitable for the decline and keeps the light output at the rated value regardless of the cumulative lighting time, thereby suppressing excess power from the initial lighting to the lifetime. In such a lighting device, it is necessary to reset the cumulative lighting time when the light source is replaced. As such means, for example, there is one that detects the end of the life of the light source or the replacement of the light source, and automatically resets the cumulative lighting time when the light source is replaced. However, in the above lighting device, even when the user intentionally removes the light source, for example, due to cleaning or maintenance, the cumulative lighting time is reset.
この問題を解決する手段として、電源スイッチのオン/オフを所定の状態で行うことで累積点灯時間をリセットするという手段が用いられている。例えば特許文献3では、所定時間における電源スイッチのオン/オフの回数を検知して所定回数を超えた場合に累積点灯時間をリセットするものが提案されている。このような手段を用いることで、光源を取り外すことなく累積点灯時間をリセットできるため、上記問題を解決することができる。また、光源の累積点灯時間を計時し、累積点灯時間が光源の寿命に近付くと利用者に通知して光源の交換を促す場合等でも累積点灯時間のリセットが必要であり、このような場合でも専用のリセットスイッチを敷設することなく既設の電源線を利用して利用者が累積点灯時間をリセットすることができる。

As means for solving this problem, means for resetting the cumulative lighting time by turning on / off the power switch in a predetermined state is used. For example, Patent Document 3 proposes a method of detecting the number of times the power switch is turned on / off in a predetermined time and resetting the cumulative lighting time when the predetermined number of times is exceeded. By using such means, the cumulative lighting time can be reset without removing the light source, so that the above problem can be solved. In addition, it is necessary to reset the cumulative lighting time even when the cumulative lighting time of the light source is timed and the user is notified when the cumulative lighting time approaches the life of the light source and prompts the user to replace the light source. The user can reset the cumulative lighting time by using an existing power line without installing a dedicated reset switch.

しかしながら、上記従来例のように電源スイッチの操作によって光源の明るさを調整可能とした照明システムと、電源スイッチの操作によって累積点灯時間をリセットする照明システムとが混在した照明システム、若しくは両者を1つに纏めた照明システムでは、光源の明るさを調整することを意図して電源スイッチを操作した場合に、誤って累積点灯時間をリセットしてしまうことがある。また、逆に累積点灯時間をリセットすることを意図して電源スイッチを操作した場合に、誤って光源の明るさを調整してしまうことも起こり得る。特に、意図せず累積点灯時間をリセットしてしまった場合には、累積点灯時間の経過とともに減退する光束を補正するように光源の明るさを調整する照明システムにおいて、光束が減退した光源を新たな光源とみなして供給電力を調整してしまうため、所望の光源の明るさを得られないという問題があった。   However, the illumination system in which the brightness of the light source can be adjusted by operating the power switch as in the above conventional example and the illumination system in which the cumulative lighting time is reset by operating the power switch, or both are combined. In an integrated lighting system, when the power switch is operated with the intention of adjusting the brightness of the light source, the cumulative lighting time may be erroneously reset. Conversely, when the power switch is operated with the intention of resetting the cumulative lighting time, the brightness of the light source may be erroneously adjusted. In particular, when the cumulative lighting time is reset unintentionally, a new light source with a reduced luminous flux is newly installed in the lighting system that adjusts the brightness of the light source so as to correct the luminous flux that declines as the cumulative lighting time elapses. Therefore, there is a problem in that the brightness of the desired light source cannot be obtained because the supplied power is adjusted as a light source.
本発明は、上記の点に鑑みて為されたもので、意図せずに光源の明るさの調整又は累積点灯時間のリセットを行うことを防止することのできる照明システム及び照明器具を提供することを目的とする。   The present invention has been made in view of the above points, and provides an illumination system and a luminaire that can prevent unintentionally adjusting the brightness of a light source or resetting the cumulative lighting time.

ここで、点灯回路部10はスイッチング素子を有するとともにスイッチング素子のオン/オフを切り替えることで放電灯Laを高周波点灯させるインバータ回路から成る。出力制御部11は、点灯回路部10におけるスイッチング素子の駆動周波数を制御するドライバ回路から成る。調光制御部14は、例えばマイコンから成り、出力制御部11における駆動周波数を決定するための調光指令値を調光レベル及び累積点灯時間に応じて演算して求める。本実施形態では、調光制御部14、記憶部13、計時部12を別構成としているが、1つのマイコンに纏めた構成であっても構わない。尚、各回路は周知であるので、ここでは詳細な説明を省略するものとする。   Here, the lighting circuit unit 10 includes a switching element and an inverter circuit that turns on the discharge lamp La at a high frequency by switching on / off the switching element.

If the power detection unit 15 detects the on / off of the power switch SW, and the on time Ton of the power switch SW is T1 ≦ Ton ≦ T2, the dimming control unit 14 determines that the number of power on times is 1. Note that T1 and T2 only need to satisfy the relationship of T1 <T2, and in this embodiment, T1 = 0.5 seconds and T2 = 3.0 seconds are set. The power-on count is stored in the storage unit 13, and the dimming control unit 14 reads the power-on count from the storage unit 13 when the power switch SW is turned on next time. When the on-time Ton is continuously detected, the power-on count is incremented once, twice, and three times, and reaches a predetermined count (six times in the present embodiment) (that is, the first power-on / off state). And the cumulative lighting time reset condition is determined and the cumulative lighting time is reset. When Ton> T2, the number of power-on times is reset to 0 as shown in FIG. When Ton <T1, the number of power-on times is maintained as shown in FIG.
次に、放電灯Laの調光レベルの切替動作について図3を用いて説明する。電源検出部15が電源スイッチSWのオン/オフを検出し、電源スイッチSWのオン時間TonがT3≦Ton≦T4であれば、調光制御部14は調光レベルの切替動作の第1条件が成立したものと判定する。この状態で次回電源スイッチSWがオンに切り替わった時にオン時間TonがT5以上になれば(即ち、第2の電源オン/オフ状態になれば)、調光制御部14は調光レベルの切替動作の第2条件が成立したものと判定し、調光レベルを切り替える。本実施形態では、調光レベルが全点灯、即ち、100%の時に調光レベルの切替動作の第1条件、第2条件が成立した場合には、図3(a)に示すように調光レベルを50%に切り替える。また、調光レベルが50%の時に調光レベルの切替動作の第1条件、第2条件が成立した場合には、図3(b)に示すように調光レベルを70%に切り替える。調光レベルが70%の時に調光レベルの切替動作の第1条件、第2条件が成立した場合には、図3(c)に示すように調光レベルを全点灯に切り替える。ここで、調光レベルの切替動作の第1条件の判定時においてTon<T3又はTon>T4の場合、及び調光レベルの切替動作の第2条件の判定時においてTon<T5の場合には、調光制御部14は調光レベルの切替動作を行わずに調光レベルを維持する。調光レベルは記憶部13に記憶されるとともに電源スイッチSWがオンに切り替わる度に読み出され、調光レベル及び累積点灯時間に応じて光束減退を補正するように調光制御部14で調光指令値を演算する。この調光指令値を出力制御部11に与えることで、点灯回路部10が放電灯Laを調光レベル及び累積点灯時間に応じた光出力で点灯させる。   Next, the dimming level switching operation of the discharge lamp La will be described with reference to FIG. When the power source detection unit 15 detects the on / off of the power switch SW and the on time Ton of the power switch SW is T3 ≦ Ton ≦ T4, the dimming control unit 14 determines that the first condition of the dimming level switching operation is It is determined that it has been established. If the on-time Ton becomes T5 or more when the power switch SW is turned on next time in this state (that is, if the second power on / off state is reached), the dimming control unit 14 performs the dimming level switching operation. It is determined that the second condition is satisfied, and the dimming level is switched. In this embodiment, when the dimming level is fully lit, that is, when the first condition and the second condition of the dimming level switching operation are satisfied when the dimming level is 100%, dimming is performed as shown in FIG. Switch the level to 50%. If the first condition and the second condition of the dimming level switching operation are satisfied when the dimming level is 50%, the dimming level is switched to 70% as shown in FIG. When the first condition and the second condition of the dimming level switching operation are satisfied when the dimming level is 70%, the dimming level is switched to full lighting as shown in FIG. Here, in the case of Ton <T3 or Ton> T4 in the determination of the first condition of the dimming level switching operation, and in the case of Ton <T5 in the determination of the second condition of the dimming level switching operation, The dimming control unit 14 maintains the dimming level without performing the dimming level switching operation. The dimming level is stored in the storage unit 13 and is read out every time the power switch SW is turned on, and the dimming control unit 14 performs dimming so as to correct the light beam decrease according to the dimming level and the cumulative lighting time. Calculate the command value. By supplying this dimming command value to the output control unit 11, the lighting circuit unit 10 lights the discharge lamp La with a light output corresponding to the dimming level and the cumulative lighting time.
尚、T3,T4はT3<T4の関係を満たすものであればよく、本実施形態ではT3=0.5秒、T4=3.0秒に設定している。また、T5は誤って累積点灯時間のリセット動作が行われるのを防止するためにT5>T2の関係を満たすように設定され、本実施形態ではT5=5.0秒に設定している。このように設定することで、累積点灯時間のリセットを意図して電源スイッチSWを操作した場合には、オン時間TonがT5よりも短くなるために調光レベルが切り替わることがない。また、調光レベルの切替を意図して電源スイッチSWを操作した場合には、オン時間TonがT2よりも長くなるために累積点灯時間をリセットすることがない。したがって、誤って累積点灯時間のリセット及び調光レベルの切替を行う可能性を大幅に低減することができる。ここで、図3(d)に示すように、調光レベルの切替動作の第1条件を成立させるのに必要な電源スイッチSWの操作回数を増やすことで、誤って調光レベルを切り替えてしまうのをより好適に防止することができる。但し、意図せずに累積点灯時間をリセットするのを防止するために、上記操作回数は電源オン回数よりも少なくなるように設定しておかなければならない。   Note that T3 and T4 need only satisfy the relationship of T3 <T4. In this embodiment, T3 = 0.5 seconds and T4 = 3.0 seconds are set. Further, T5 is set so as to satisfy the relationship of T5> T2 in order to prevent the reset operation of the cumulative lighting time from being erroneously performed, and in this embodiment, T5 = 5.0 seconds. With this setting, when the power switch SW is operated with the intention of resetting the cumulative lighting time, the light control level will not be switched because the on time Ton is shorter than T5. Further, when the power switch SW is operated with the intention of switching the light control level, the on-time Ton becomes longer than T2, and thus the cumulative lighting time is not reset. Therefore, the possibility of erroneously resetting the cumulative lighting time and switching the dimming level can be greatly reduced. Here, as shown in FIG. 3D, the dimming level is erroneously switched by increasing the number of operations of the power switch SW necessary to establish the first condition of the dimming level switching operation. Can be more suitably prevented. However, in order to prevent the cumulative lighting time from being reset unintentionally, the number of operations must be set to be smaller than the number of power-on times.
尚、本実施形態ではT5>T2となるように設定しているが、T3>T2、又はT4<T1となるように設定した場合においても上記の誤動作を防止する効果を得ることができる。また、本実施形態では、累積点灯時間を計時することで累積点灯時間に応じた光束の減退を補正するように構成しているが、累積点灯時間に応じて放電灯Laの寿命を判定して寿命が末期であることを利用者に通知する構成であっても構わない。また、本実施形態では電源スイッチSWのオン時間Tonによって各動作の成立条件を判定しているが、電源スイッチSWのオフ時間で各動作の成立条件を判定する構成であっても構わない。また、本実施形態では、調光レベルの切替動作において調光レベルを全点灯、50%、70%の順に切り替える構成となっているが、上記以外の調光レベルや順序、又は切替回数で調光レベルの切替動作を行うように構成しても構わない。また、本実施形態の点灯装置1は1つの回路ブロックで構成しているが、各種制御を行う制御回路ブロックと、制御回路ブロックからの信号に応じて放電灯Laの調光点灯を行う点灯回路ブロックとに分けて構成しても構わない。   In the present embodiment, T5> T2 is set. However, even when T3> T2 or T4 <T1 is set, the effect of preventing the malfunction can be obtained. Further, in the present embodiment, the cumulative lighting time is measured to correct the decrease in luminous flux according to the cumulative lighting time, but the life of the discharge lamp La is determined according to the cumulative lighting time. You may be the structure which notifies a user that the lifetime is the last stage. In this embodiment, the conditions for establishing each operation are determined based on the on-time Ton of the power switch SW. However, the conditions for establishing each operation may be determined based on the off-time of the power switch SW. In this embodiment, the dimming level is switched in the order of full lighting, 50%, and 70% in the dimming level switching operation. You may comprise so that the switching operation of a light level may be performed. Moreover, although the lighting device 1 of this embodiment is comprised by one circuit block, the lighting circuit which performs the light control lighting of the discharge lamp La according to the signal from the control circuit block which performs various controls, and a control circuit block It may be divided into blocks.
本実施形態の点灯装置1は、例えば図4に示すように、放電灯Laが着脱自在に装着される一対のソケット20を有する長尺箱形の器具本体2に収納されて照明器具として用いられ、また、複数(ここでは、照明器具A〜Z)の照明器具と1つの電源スイッチSWとの間を電源線Lを介して送り接続した照明システムに用いられる。   For example, as shown in FIG. 4, the lighting device 1 of the present embodiment is housed in a long box-shaped fixture body 2 having a pair of sockets 20 to which a discharge lamp La is detachably attached and used as a lighting fixture. In addition, it is used in a lighting system in which a plurality of (here, lighting fixtures A to Z) lighting fixtures and one power switch SW are connected via a power line L.
ここで、例えば上記照明器具A〜Zのうち半数に第1の点灯装置を内蔵し、残りの半数に第2の点灯装置を内蔵した場合を考える。この場合でも上記と同様の効果を奏することができる。即ち、第1の点灯装置を内蔵した照明器具における累積点灯時間のリセットを意図して電源スイッチSWを操作した場合、誤って第2の点灯装置を内蔵した照明器具において調光レベルが切り替えられるのを防止することができる。同様に、第2の点灯装置を内蔵した照明器具における調光レベルの切替を意図して電源スイッチSWを操作した場合においても、誤って第1の点灯装置を内蔵した照明器具において累積点灯時間がリセットされるのを防止することができる。   Here, for example, consider a case where the first lighting device is built in half of the lighting fixtures A to Z and the second lighting device is built in the remaining half. Even in this case, the same effect as described above can be obtained. That is, when the power switch SW is operated to reset the accumulated lighting time in the lighting fixture incorporating the first lighting device, the dimming level is erroneously switched in the lighting fixture incorporating the second lighting device. Can be prevented. Similarly, even when the power switch SW is operated with the intention of switching the dimming level in the lighting fixture incorporating the second lighting device, the cumulative lighting time in the lighting fixture incorporating the first lighting device by mistake. It can be prevented from being reset.
(実施形態2)
以下、本発明に係る照明システムの実施形態2について図面を用いて説明する。但し、本実施形態の基本的な構成は実施形態1と共通であるので、共通する部位には同一の番号を付して説明を省略するものとする。本実施形態は、調光レベルの切替動作が行われた事を利用者に通知するために、調光レベルの切替動作時において前状態の調光レベルがどのレベルであっても、一旦放電灯Laを全点灯させた後に離散的に調光レベルを切り替えることに特徴がある。
(Embodiment 2)
Hereinafter, Embodiment 2 of the illumination system according to the present invention will be described with reference to the drawings. However, since the basic configuration of this embodiment is the same as that of the first embodiment, common portions are denoted by the same reference numerals and description thereof is omitted. In this embodiment, in order to notify the user that the dimming level switching operation has been performed, the discharge lamp is temporarily turned on regardless of the dimming level in the previous state during the dimming level switching operation. It is characterized in that the dimming level is switched discretely after turning on all of La.
以下、本実施形態の動作について図5を用いて説明する。尚、本実施形態の調光レベルの切替動作は、実施形態1と同様に調光レベルを全点灯、50%、70%の順に切り替える構成であるとする。図5(a)に示すように、電源検出部15が電源スイッチSWのオン/オフを検出し、実施形態1と同様に電源スイッチSWのオン時間TonがT3≦Ton≦T4であれば、調光制御部14は調光レベルの切替動作の第1条件が成立したものと判定する。この状態で次回電源スイッチSWがオンに切り替わると、現時点での調光レベルに依らず放電灯Laが全点灯の光出力で先ず点灯する。その後、オン時間TonがT5以上になれば、調光制御部14は調光レベルの切替動作の第2条件が成立したものと判定し、調光レベルを切り替える。   Hereinafter, the operation of the present embodiment will be described with reference to FIG. The dimming level switching operation of the present embodiment is configured to switch the dimming level in the order of full lighting, 50%, and 70% as in the first embodiment. As shown in FIG. 5A, when the power detection unit 15 detects the on / off of the power switch SW and the on-time Ton of the power switch SW is T3 ≦ Ton ≦ T4 as in the first embodiment, the adjustment is performed. The light control unit 14 determines that the first condition of the dimming level switching operation is satisfied. When the power switch SW is turned on next time in this state, the discharge lamp La is first lit with the light output of all lighting regardless of the current dimming level. Thereafter, when the on-time Ton becomes T5 or more, the dimming control unit 14 determines that the second condition of the dimming level switching operation is satisfied, and switches the dimming level.
ここで、調光レベルを全点灯から50%に切り替える場合には、電源スイッチSWがオンに切り替わってからT5になるまでの間全点灯の光出力で放電灯Laが点灯し、T5以降T6の間だけ70%の光出力で放電灯Laが点灯し、後に50%の光出力で放電灯Laが点灯する。調光レベルを50%から70%に切り替える場合には、電源スイッチSWがオンに切り替わってからT5になるまでの間全点灯の光出力で放電灯Laが点灯し、その後70%の光出力で放電灯Laが点灯する。   Here, when the dimming level is switched from full lighting to 50%, the discharge lamp La is lit with the light output of all lighting until the power switch SW is turned on until T5. The discharge lamp La is lit at a light output of 70% only during the interval, and later the discharge lamp La is lit at a light output of 50%. When the dimming level is switched from 50% to 70%, the discharge lamp La is turned on with the light output of all lighting until the power switch SW is turned on until T5, and then the light output of 70%. The discharge lamp La lights up.
また、例えば調光レベルの切替動作が調光レベルを全点灯、75%、50%、25%の順に切り替える構成であるとすると、図5(b)に示すように、調光レベルを50%から25%に切り替える場合には、電源スイッチSWがオンに切り替わってからT5になるまでの間全点灯の光出力で放電灯Laが点灯し、T5以降それぞれT6の間だけ75%、50%の光出力で離散的に放電灯Laが点灯し、その後25%の光出力で放電灯Laが点灯する。   Further, for example, when the dimming level switching operation is configured to switch the dimming level in the order of full lighting, 75%, 50%, and 25%, the dimming level is set to 50% as shown in FIG. In the case of switching from 25% to 25%, the discharge lamp La lights up with the light output of all lighting from the time when the power switch SW is turned on until T5, and 75% and 50% of the time between T5 and T6 respectively. The discharge lamp La is lighted discretely with the light output, and then the discharge lamp La is lighted with a light output of 25%.
上述のように、目標となる調光レベルまで全点灯の調光レベルから離散的に切り替えていくことで、調光レベルの切替動作が行われたことを目視で確認することができる。特に、調光レベルが低くどの調光レベルに切り替えたかを目視で確認し難い場合でも容易に確認することができる。尚、T6は離散的に調光レベルが切り替わるのを利用者が確認し易いように例えば1秒程度に設定するのが望ましい。また、本実施形態では調光レベルを全点灯から離散的に切り替えているが、低い調光レベルから高い調光レベルへと離散的に切り替えるようにしても構わない。また、電源スイッチSWをオンに切り替える度に調光レベルを全点灯から現在の調光レベルへと離散的に切り替える、若しくは低い調光レベルから現在の調光レベルへと離散的に切り替えるように構成しても構わない。この場合、電源スイッチSWをオンにする度に現在の調光レベルを確認することができる。   As described above, it is possible to visually confirm that the dimming level switching operation has been performed by discretely switching from the fully lit dimming level to the target dimming level. In particular, even when the dimming level is low and it is difficult to visually check which dimming level is switched to, it can be easily confirmed. It should be noted that T6 is preferably set to, for example, about 1 second so that the user can easily confirm that the dimming level is switched discretely. In the present embodiment, the dimming level is switched discretely from full lighting, but may be switched discretely from a low dimming level to a high dimming level. Further, every time the power switch SW is turned on, the dimming level is discretely switched from full lighting to the current dimming level, or is switched discretely from a low dimming level to the current dimming level. It doesn't matter. In this case, the current dimming level can be confirmed every time the power switch SW is turned on.
(実施形態3)
以下、本発明に係る照明システムの実施形態3について図面を用いて説明する。但し、本実施形態の基本的な構成は実施形態1と共通であるので、共通する部位には同一の番号を付して説明を省略するものとする。本実施形態は、調光レベルの切替動作時において所定の時間(例えば数秒〜数十秒)だけ調光レベルが予め設定された順番で自動的に切り替わる調光レベル設定モードとなり、当該モードにおいて利用者が設定したい調光レベルの時に電源スイッチSWをオフに切り替えることで調光レベルを設定することに特徴がある。
(Embodiment 3)
Hereinafter, Embodiment 3 of the illumination system according to the present invention will be described with reference to the drawings. However, since the basic configuration of this embodiment is the same as that of the first embodiment, common portions are denoted by the same reference numerals and description thereof is omitted. This embodiment is a dimming level setting mode in which the dimming level is automatically switched in a predetermined order for a predetermined time (for example, several seconds to several tens of seconds) during the dimming level switching operation, and is used in this mode. It is characterized in that the dimming level is set by switching off the power switch SW at the dimming level that the person wants to set.
以下、本実施形態の動作について図6を用いて説明する。図6(a)に示すように、電源検出部15が電源スイッチSWのオン/オフを検出し、実施形態1と同様に電源スイッチSWのオン時間TonがT3≦Ton≦T4であれば、調光制御部14は調光レベルの切替動作の第1条件が成立したものと判定する。この状態で次回電源スイッチSWがオンに切り替わると、現時点での調光レベルに依らず放電灯Laが全点灯の光出力で先ず点灯する。その後、オン時間TonがT5以上になれば、調光制御部14は調光レベルの切替動作の第2条件が成立したものと判定し、上述の調光レベル設定モードに移行する。調光レベル設定モードでは、例えば5秒毎に調光レベルが全点灯、75%、50%、25%、全点灯の順に自動的に切り替わる。この調光レベル設定モードにおいて電源スイッチSWのオフ操作(即ち、第3の電源オン/オフ状態)を検出すると、調光制御部14はオフ操作を検出した時点における調光レベルを記憶部13に記憶する。そして、次回電源スイッチSWがオンに切り替わった時には、調光制御部14が記憶部13に記憶された調光レベルを読み出して、調光レベルに応じて放電灯Laを点灯させる。而して、電源スイッチSWの簡単なオン/オフ操作によって調光レベルを容易に変更することができる。   Hereinafter, the operation of the present embodiment will be described with reference to FIG. As shown in FIG. 6A, when the power detection unit 15 detects the on / off of the power switch SW and the on time Ton of the power switch SW is T3 ≦ Ton ≦ T4 as in the first embodiment, the adjustment is performed. The light control unit 14 determines that the first condition of the dimming level switching operation is satisfied. When the power switch SW is turned on next time in this state, the discharge lamp La is first lit with the light output of all lighting regardless of the current dimming level. Thereafter, when the on-time Ton is equal to or greater than T5, the dimming control unit 14 determines that the second condition of the dimming level switching operation is satisfied, and shifts to the dimming level setting mode. In the dimming level setting mode, for example, every 5 seconds, the dimming level is automatically switched in the order of full lighting, 75%, 50%, 25%, and full lighting. When an off operation of the power switch SW (that is, the third power on / off state) is detected in the dimming level setting mode, the dimming control unit 14 stores the dimming level at the time when the off operation is detected in the storage unit 13. Remember. When the power switch SW is turned on next time, the dimming control unit 14 reads the dimming level stored in the storage unit 13 and lights the discharge lamp La according to the dimming level. Thus, the dimming level can be easily changed by a simple on / off operation of the power switch SW.
尚、調光レベル設定モードにおいて調光レベルが順に自動的に切り替わる回数に制限を設け、制限を越えるまでに電源スイッチSWのオフ操作が検出されなかった場合には調光レベル設定モードに移行する前の調光レベルに復帰するようにしても構わない。例えば図6(b)に示すように、調光レベルが75%の状態で調光レベル設定モードに移行し、制限回数である2回を越えるまでに電源スイッチSWのオフ操作が検出されなかった場合、再び調光レベルが75%に復帰する。上述のように構成することで、利用者が意図せずに電源スイッチSWを操作して調光レベル設定モードに移行した場合でも、調光レベルを切り替えることなく調光レベル設定モードを終了させることができる。   In the dimming level setting mode, a limit is set on the number of times that the dimming level automatically switches in order, and if the turning-off operation of the power switch SW is not detected before the limit is exceeded, the dimming level setting mode is entered. You may make it return to the former light control level. For example, as shown in FIG. 6 (b), when the dimming level is 75%, the mode shifts to the dimming level setting mode, and the power switch SW OFF operation is not detected until the limit of 2 times is exceeded. In this case, the dimming level returns to 75% again. By configuring as described above, even when the user unintentionally operates the power switch SW to shift to the dimming level setting mode, the dimming level setting mode is terminated without switching the dimming level. Can do.
また、調光レベル設定モードにおいて調光レベルを離散的に切り替えるのではなく、図6(c)に示すように調光レベルを無段階で連続的に変化させる構成であっても構わない。この場合、利用者の所望する調光レベルに自由に設定することができる。   Further, instead of discretely switching the dimming level in the dimming level setting mode, a configuration in which the dimming level is continuously changed steplessly as shown in FIG. In this case, the light control level desired by the user can be freely set.
(実施形態4)
以下、本発明に係る照明システムの実施形態4について図面を用いて説明する。但し、本実施形態の基本的な構成は実施形態1と共通であるので、共通する部位には同一の番号を付して説明を省略するものとする。本実施形態は、図7(a)に示すように、負荷である放電灯Laが接続されているか否かを検出する負荷検出部16を備えたことに特徴がある。
(Embodiment 4)
Hereinafter, Embodiment 4 of the illumination system according to the present invention will be described with reference to the drawings. However, since the basic configuration of this embodiment is the same as that of the first embodiment, common portions are denoted by the same reference numerals and description thereof is omitted. As shown in FIG. 7A, the present embodiment is characterized in that a load detection unit 16 that detects whether or not a discharge lamp La that is a load is connected is provided.
以下、本実施形態の動作について説明する。負荷検出部16は、放電灯Laが接続されているか否かを検出し、検出結果を含む検出信号を調光制御部14へ出力する。調光制御部14は、負荷検出部16からの検出信号が有負荷の場合には、電源スイッチSWのオン/オフ操作が条件を満たせば前述の各実施形態と同様に調光レベルの切替動作を行う。負荷検出部16からの検出信号が無負荷の場合には、電源スイッチSWのオン/オフ操作が条件を満たしても調光レベルの切替動作を行わず、現時点の調光レベルを維持する。このように構成することで、例えば図7(b)に示すように複数台(図示では4台)の照明器具を1組として複数組(図示では5組)を電源線Lを介して並列に接続して成る照明システムにおいて、調光レベルを切り替えたい組(例えば、照明器具A〜D,I〜L,Q〜T)に放電灯Laを装着して有負荷にし、調光レベルを切り替えたくない組(例えば、照明器具E〜H,M〜P)に放電灯Laを装着せずに無負荷にすれば、電源スイッチSWのオン/オフ操作によって有負荷の照明器具のみの調光レベルを切り替えることができる。特に、フロア全体の照明器具が1つの電源に繋がっている照明システム等において、フロアのレイアウトを変更する時に照明器具の組毎に調光レベルを設定することができて非常に有効である。   Hereinafter, the operation of this embodiment will be described. The load detection unit 16 detects whether or not the discharge lamp La is connected, and outputs a detection signal including the detection result to the dimming control unit 14. When the detection signal from the load detection unit 16 has a load, the dimming control unit 14 switches the dimming level as in the above-described embodiments as long as the on / off operation of the power switch SW satisfies the condition. I do. When the detection signal from the load detection unit 16 is no load, the dimming level is not switched even if the on / off operation of the power switch SW satisfies the condition, and the current dimming level is maintained. With this configuration, for example, as shown in FIG. 7B, a plurality of lighting fixtures (four in the drawing) are set as one set, and a plurality of lighting fixtures (five in the drawing) are connected in parallel via the power line L. In a connected lighting system, a discharge lamp La is attached to a group (for example, lighting fixtures A to D, I to L, and Q to T) for which the dimming level is to be switched, and the dimming level is switched. If there is no load without attaching the discharge lamp La to a set (for example, lighting fixtures E to H, M to P), the dimming level of only the loaded lighting fixture can be increased by turning on / off the power switch SW. Can be switched. In particular, in a lighting system or the like in which lighting fixtures for the entire floor are connected to a single power source, the dimming level can be set for each set of lighting fixtures when changing the floor layout, which is very effective.
(実施形態5)
以下、本発明に係る照明システムの実施形態5について図面を用いて説明する。但し、本実施形態の基本的な構成は実施形態1と共通であるので、共通する部位には同一の番号を付して説明を省略するものとする。本実施形態は、電源スイッチSWのオン/オフ操作によって現時点の調光レベルを全点灯の調光レベルにリセットできることに特徴がある。
(Embodiment 5)
Hereinafter, Embodiment 5 of the illumination system according to the present invention will be described with reference to the drawings. However, since the basic configuration of this embodiment is the same as that of the first embodiment, common portions are denoted by the same reference numerals and description thereof is omitted. The present embodiment is characterized in that the current dimming level can be reset to a fully lit dimming level by an on / off operation of the power switch SW.
以下、本実施形態の動作について図面を用いて説明する。図8に示すように、電源検出部15が電源スイッチSWのオン/オフを検出し、電源スイッチSWのオン時間TonがT3≦Ton≦T4であれば、調光制御部14は調光レベルリセット用の電源オン回数を1と判定する。この電源オン回数は記憶部13に記憶され、次回電源スイッチSWがオンに切り替わった時点で調光制御部14が電源オン回数を記憶部13から読み出す。このオン時間Tonを連続で検出すると電源オン回数は1回、2回と加算されていき、所定回数(本実施形態では3回)に達した後、次回電源スイッチSWがオンに切り替わった時にオン時間TonがT5以上になれば(即ち、第4の電源オン/オフ状態になれば)、調光レベルのリセット条件が成立したと判定して調光レベルを全点灯の調光レベルにリセットする。   Hereinafter, the operation of the present embodiment will be described with reference to the drawings. As shown in FIG. 8, if the power detection unit 15 detects ON / OFF of the power switch SW and the ON time Ton of the power switch SW is T3 ≦ Ton ≦ T4, the dimming control unit 14 resets the dimming level. It is determined that the number of power-on times for use is 1. The power-on count is stored in the storage unit 13, and the dimming control unit 14 reads the power-on count from the storage unit 13 when the power switch SW is turned on next time. When this on-time Ton is continuously detected, the number of times the power is turned on is incremented once and twice, and after the predetermined number of times (three times in the present embodiment) is reached, the power is turned on the next time the power switch SW is turned on. When the time Ton is equal to or greater than T5 (that is, when the fourth power supply is turned on / off), it is determined that the dimming level reset condition is satisfied, and the dimming level is reset to the fully lit dimming level. .
上述のように構成することで、例えば複数の照明器具から成る照明システムにおいて、照明器具毎にオン時間Tonを検出する時間にバラツキがあり、一部の照明器具だけの調光レベルが切り替えられて各照明器具の調光レベルがバラバラになった場合でも、全ての照明器具において同じ調光レベルにリセットすることができる。尚、調光レベルのリセット条件を成立させるために必要な電源オン回数は、累積点灯時間のリセット条件を成立させるために必要な電源オン回数よりも少なくするのが望ましい。このように構成することで、調光レベルをリセットしようとして意図せずに累積点灯時間をリセットしてしまう事を防止することができる。   By configuring as described above, for example, in a lighting system including a plurality of lighting fixtures, there is variation in the time to detect the on-time Ton for each lighting fixture, and the dimming level of only some of the lighting fixtures is switched. Even when the dimming levels of the respective lighting fixtures vary, it is possible to reset to the same dimming level in all the lighting fixtures. It is desirable that the number of power-on times required to satisfy the dimming level reset condition is smaller than the number of power-on times required to satisfy the cumulative lighting time reset condition. With this configuration, it is possible to prevent the cumulative lighting time from being reset unintentionally in an attempt to reset the dimming level.
(実施形態6)
以下、本発明に係る照明システムの実施形態6について図面を用いて説明する。但し、本実施形態の基本的な構成は実施形態1と共通であるので、共通する部位には同一の番号を付して説明を省略するものとする。本実施形態は、累積点灯時間のリセット条件を成立させるために必要なオン時間Tonと、調光レベルの切替条件を成立させるために必要なオン時間Tonとを同一とし、累積点灯時間のリセット条件を成立させるために必要な電源オン回数と調光レベルの切替条件を成立させるために必要な電源オン回数とを互いに異なる回数としたことに特徴がある。
(Embodiment 6)
Hereinafter, Embodiment 6 of the illumination system according to the present invention will be described with reference to the drawings. However, since the basic configuration of this embodiment is the same as that of the first embodiment, common portions are denoted by the same reference numerals and description thereof is omitted. In the present embodiment, the on-time Ton necessary for establishing the reset condition for the cumulative lighting time and the on-time Ton necessary for establishing the dimming level switching condition are the same, and the reset condition for the cumulative lighting time is set. The feature is that the number of times of turning on the power necessary to establish the condition and the number of times of turning on the power necessary to establish the dimming level switching condition are different from each other.
以下、本実施形態の動作について図面を用いて説明する。図9に示すように、電源検出部15が電源スイッチSWのオン/オフを検出し、電源スイッチSWのオン時間TonがT1≦Ton≦T2であれば、調光制御部14は電源オン回数を1と判定する。この電源オン回数は記憶部13に記憶され、次回電源スイッチSWがオンに切り替わった時点で調光制御部14が電源オン回数を記憶部13から読み出す。このオン時間Tonを連続で検出すると電源オン回数は1回、2回と加算されていき、所定回数(本実施形態では3回)に達すると、調光制御部14は調光レベルの切替条件が成立したものと判定し、調光レベルを切り替える(ここでは、全点灯から50%)。次に、電源オン回数が所定回数(本実施形態では6回)に達すると、調光制御部14は累積点灯時間のリセット条件が成立したものと判定し、累積点灯時間をリセットする。同時に、調光レベルを初期値(ここでは全点灯)にリセットする。   Hereinafter, the operation of the present embodiment will be described with reference to the drawings. As shown in FIG. 9, if the power detection unit 15 detects the on / off of the power switch SW and the on time Ton of the power switch SW is T1 ≦ Ton ≦ T2, the dimming control unit 14 determines the number of times the power is turned on. 1 is determined. The power-on count is stored in the storage unit 13, and the dimming control unit 14 reads the power-on count from the storage unit 13 when the power switch SW is turned on next time. When the on-time Ton is continuously detected, the number of power-on times is incremented once and twice, and when the predetermined number of times (three times in the present embodiment) is reached, the dimming control unit 14 sets the dimming level switching condition. Is determined and the dimming level is switched (here, 50% from full lighting). Next, when the number of power-on times reaches a predetermined number (six times in the present embodiment), the dimming control unit 14 determines that the accumulated lighting time reset condition is satisfied, and resets the accumulated lighting time. At the same time, the dimming level is reset to the initial value (here, all lights up).
上述のように構成することで、調光レベルを切り替えることを意図して電源スイッチSWを操作した場合には累積点灯時間をリセットしてしまう事が無く、累積点灯時間のリセットを意図して電源スイッチSWを操作した場合には同時に調光レベルがリセットされるので、誤って調光レベルを設定したり誤って累積点灯時間及び調光レベルをリセットしたりする可能性を低減することができる。   With the configuration described above, when the power switch SW is operated with the intention of switching the dimming level, the cumulative lighting time is not reset, and the power source is intended to reset the cumulative lighting time. When the switch SW is operated, the dimming level is reset at the same time, so that the possibility of erroneously setting the dimming level or erroneously resetting the cumulative lighting time and the dimming level can be reduced.
