従来、商用電源の事故や、分電盤の主幹ブレーカやリミッタの動作によって停電が夜間に発生した場合、ランプによって分電盤の周囲を照らして暗闇の中でも点検や復旧作業が容易にできるように分電盤に停電用保安灯を備えたものがある。この停電用保安灯はランプや二次電池等の構成部品を別体に形成して分電盤内に別々に配設したり、分岐ブレーカ群の右側の機器取り付け用スペースに取り付けたり、分岐ブレーカと同一サイズに形成したケースによって分岐ブレーカの1つと置き換えて取り付けたりし、ランプの電源は一次電池又は二次電池を使用していた(例えば、特許文献1〜3参照。)。

【発明が解決しようとする課題】
そのため、従来の停電用保安灯は長期間使用すると電池を交換しなければならないし、電池の残量を確認するためにランプが点灯するかどうかをテストするテスト回路が必要であるし、電池を廃棄する必要があるため、環境保護の点から好ましくなかった。また、停電用保安灯の構成部品を別体に形成して分電盤内の別々の場所に配設する場合は、各部品間の電線の接続が煩雑になったり、ブレーカへの配線の邪魔になるし、停電用保安灯を機器取り付け用スペースに配設する場合は機器取り付け用スペースを確保するために分電盤が大型化するし、停電用保安灯を分岐ブレーカの取り付けスペースに設置する場合は分岐ブレーカの取り付けスペースが減少し、而も上下の分岐ブレーカの数がアンバランスになるという欠点があった。
【0005】
そこで上記問題点に鑑み、本発明の目的は、電池の交換を不要とし、電池廃棄による環境汚染の問題が無く、電池の残量確認のためのテスト回路を必要とせず、また、小型化が可能で分電盤内の有効スペースを減少させずに取り付けることができる停電用保安灯を提供することである。

【0010】
請求項2に記載の発明によれば、請求項1に記載の停電用保安灯において、ランプに流れる電流を一定に保つための定電流回路を備えたことにより、ランプの破損を防止し、輝度を一定にすることができる。

【0012】
【実施例】
本発明に係る停電用保安灯の実施例を図1〜図4の添付図面に基づいて説明する。
【0013】
まず、停電用保安灯1の回路について説明する。停電用保安灯1は、図1に示すように2つの端子部P1,P2間に雷サージから回路を保護するためのサージ吸収素子ZNR1が接続され、また、端子部の一方P1に電圧降下用の並列接続したコンデンサC1と抵抗R1が接続され、他方P2にヒューズ抵抗FR1が接続され、これらの間に全波整流回路DB1が接続されている。全波整流回路DB1の出力端間にはツェナーダイオードZD1と平滑コンデンサC2とが接続されて交流−直流変換回路2を構成し、交流−直流変換回路2の出力の正極線aには抵抗R2とダイオードD1が直列接続され、ダイオードD1のカソードにPNP型トランジスタTR1のエミッタが接続されている。PNP型トランジスタTR1のベースは抵抗R3を介して一端を負極線bに接続した抵抗R4の他端とダイオードD1のアノードとの接続点に接続され、コレクタは定電流回路3の電界効果トランジスタFET1のドレインに接続されている。定電流回路3は電界効果トランジスタFET1のソースに制限抵抗R5の一端を接続し、制限抵抗R5の他端をゲートに接続して構成している。定電流回路3の制限抵抗R5の他端は発光ダイオードLED1のアノードに接続され、カソードは負極線bに接続されている。発光ダイオードLED1には輝度の高い白色発光ダイオードを用いると良い。また、正極線aと負極線bとの間に内部抵抗の小さい2個の電気2重層コンデンサC3,C4が直列接続され、夫々の電気2重層コンデンサC3,C4と並列にコンデンサ保護用のツェナーダイオードZD2,ZD3が接続され、2個の電気2重層コンデンサC3,C4にかかる電圧がほぼ等しくなるようにして過電圧による破損を防止している。
【0014】
次に停電用保安灯1の動作について説明する。停電用保安灯1が通電している時、端子部P1,P2から入力された交流電圧は並列接続したコンデンサC1と抵抗R1とで降圧され、全波整流回路DB1とツェナーダイオードZD1と平滑コンデンサC2とで構成される交流−直流変換回路2によって交流電圧から直流電圧に変換される。PNP型トランジスタTR1はベースに電圧が印加されるのでターンオフの状態にあり、発光ダイオードLED1は消灯している。また、電気2重層コンデンサC3,C4は充電されている。
【0015】
そして、商用電源の事故や、分電盤の主幹ブレーカやリミッタの動作によって停電用保安灯1への通電が停止すると、PNP型トランジスタTR1のベース電圧が低下してターンオンする。これにより、電気2重層コンデンサC3,C4に蓄積された電荷がPNP型トランジスタTR1と定電流回路3を介して発光ダイオードLED1に通電し、点灯する。発光ダイオードLED1が点灯している間は暗闇の中でも分電盤の位置がすぐに分かり、点検や復帰作業を行うことができる。尚、定電流回路3は電気2重層コンデンサC3,C4から急激に放電されて起こる過電流による破壊から発光ダイオードLED1を保護すると共に、長時間にわたって発光ダイオードLED1を一定の輝度で点灯させる役割を果たしている。
【0016】
復電すると、PNP型トランジスタTR1のベース電圧が再び上昇してターンオフし、発光ダイオードLED1が消灯すると共に電気2重層コンデンサC3,C4が充電される。
【0017】
こうして構成された回路はプリント基板に実装されて図2に示すように樹脂製のケース4に収納され、住宅用分電盤5等に設けられる。住宅用分電盤5は図3に示すように主幹ブレーカ6から右方向に延びるように配設された主幹バー7を挟むように上下両側に複数の分岐ブレーカ8が並設され、主幹ブレーカ6の負荷側端子6aと主幹バー7の一端とを接続バー9によって接続して成っている。停電用保安灯1は図2に示すように接続バー10を被覆する樹脂カバー10の前面に設置され、主幹ブレーカ6の負荷側端子6aに停電用保安灯1の端子部P1,P2に接続した電線11を接続して用いられる。停電用保安灯1のケース4の前面には発光ダイオードLED1が設けられ、図4に示すように住宅用分電盤5の前面カバー12から発光ダイオードLED1が露出するように配設される。
【0018】
このため、停電用保安灯1の発光ダイオードLED1は停電時にブレーカやリミッタのハンドル付近を照らすので点検や復帰作業がしやすくなっている。また、分電盤内の配線の邪魔にならない。
【0019】
尚、本実施例において電気2重層コンデンサを2個使用したが、これに限定はなく、1個でも良いし、3個以上でも良い。このとき、2個以上の電気2重層コンデンサを使用する場合は電気2重層コンデンサに対してツェナーダイオードが並列となるように接続する。
【0020】
【発明の効果】
以上説明したように請求項1に記載の発明によれば、停電時にランプが点灯して分電盤の周囲を照らす停電用保安灯において、ランプの電源を電気2重層コンデンサで構成したことにより、電池を使用していないので交換の手間が無いし、電池廃棄による環境汚染の問題が無く、電池の残量確認のためのテスト回路を必要としない。また、小型化が可能なので分電盤に配設する場合に接続バーと分電盤の前面カバーとの間に取り付けることができ、ブレーカへの配線等の邪魔にならず、分電盤内の有効スペースを減少させないという効果がある。
【0021】
請求項2に記載の発明によれば、請求項1に記載の停電用保安灯において、ランプに流れる電流を一定に保つための定電流回路を備えたことにより、過電圧によるランプの破損を防止し、輝度を一定にすることができるという効果がある。
【0022】
請求項3に記載の発明によれば、請求項1又は請求項2に記載の停電用保安灯において、電気2重層コンデンサを直列に複数接続したことにより、充電電流を高くし、白色発光ダイオードを使用しても長時間に亘って十分な輝度を得ることができるという効果がある。

[Problems to be solved by the invention]
For this reason, the conventional power failure safety light must be replaced after a long use, and a test circuit is needed to test whether the light is on to check the remaining battery power. Since it must be discarded, it is not preferable from the viewpoint of environmental protection. Also, when the components of the safety light for power outage are formed separately and installed in different places in the distribution board, the connection of the wires between the components becomes complicated, and the wiring to the breaker is obstructed. If the security light for power failure is installed in the space for equipment installation, the distribution board will be enlarged to secure the space for equipment installation, and the security light for power failure will be installed in the installation space for the branch breaker. In such a case, there is a disadvantage that the space for mounting the branch breakers is reduced and the number of upper and lower branch breakers is unbalanced.

[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
According to the first aspect of the present invention, in a power failure security light in which a lamp is turned on at the time of a power failure and illuminates the periphery of the distribution board, the power supply of the lamp is constituted by an electric double-layer capacitor, thereby eliminating the need for battery replacement. As a result, there is no problem of environmental pollution due to battery disposal, and a test circuit for checking the remaining battery level is not required. In addition, it can be downsized and can be mounted without reducing the effective space in the distribution board.
[0010]
According to the second aspect of the present invention, in the power failure security light according to the first aspect, the constant current circuit for keeping the current flowing through the lamp constant is provided, thereby preventing damage to the lamp and improving brightness. Can be kept constant.
[0011]
According to the third aspect of the present invention, in the power failure safety light according to the first or second aspect, by connecting a plurality of electric double layer capacitors in series, the charging voltage is increased, and the white light emitting diode is used. Even when used, sufficient luminance can be obtained for a long time.
[0012]
【Example】
An embodiment of a security light for power failure according to the present invention will be described with reference to the accompanying drawings of FIGS.
[0013]
First, the circuit of the security light 1 for power failure will be described. As shown in FIG. 1, the power failure security light 1 has a surge absorbing element ZNR1 connected between two terminals P1 and P2 for protecting a circuit from lightning surge, and one of the terminals P1 for voltage drop. Are connected to a resistor C1 and a resistor R1, and a fuse resistor FR1 is connected to P2, and a full-wave rectifier circuit DB1 is connected between them. A Zener diode ZD1 and a smoothing capacitor C2 are connected between the output terminals of the full-wave rectifier circuit DB1 to form an AC-DC converter circuit 2, and a positive electrode a of the output of the AC-DC converter circuit 2 has a resistor R2 and a resistor R2. The diode D1 is connected in series, and the cathode of the diode D1 is connected to the emitter of the PNP transistor TR1. The base of the PNP transistor TR1 is connected via a resistor R3 to the connection point between the other end of the resistor R4, one end of which is connected to the negative line b, and the anode of the diode D1, and the collector is connected to the field effect transistor FET1 of the constant current circuit 3. Connected to drain. The constant current circuit 3 is configured such that one end of a limiting resistor R5 is connected to the source of the field effect transistor FET1, and the other end of the limiting resistor R5 is connected to the gate. The other end of the limiting resistor R5 of the constant current circuit 3 is connected to the anode of the light emitting diode LED1, and the cathode is connected to the negative line b. As the light emitting diode LED1, a white light emitting diode having high luminance is preferably used. Two electric double-layer capacitors C3 and C4 having a small internal resistance are connected in series between the positive electrode line a and the negative electrode line b, and a Zener diode for capacitor protection is connected in parallel with each of the electric double-layer capacitors C3 and C4. ZD2 and ZD3 are connected so that the voltages applied to the two electric double-layer capacitors C3 and C4 are substantially equal to each other to prevent damage due to overvoltage.
[0014]
Next, the operation of the security light 1 for power failure will be described. When the power failure security light 1 is energized, the AC voltage input from the terminals P1 and P2 is stepped down by the capacitor C1 and the resistor R1 connected in parallel, and the full-wave rectifier circuit DB1, the Zener diode ZD1 and the smoothing capacitor C2 Is converted from an AC voltage to a DC voltage. The PNP transistor TR1 is turned off because a voltage is applied to the base, and the light emitting diode LED1 is turned off. The electric double-layer capacitors C3 and C4 are charged.
[0015]
Then, when the power supply to the power failure protection light 1 is stopped due to a commercial power supply accident or the operation of the main breaker or limiter of the distribution board, the base voltage of the PNP transistor TR1 is reduced and the PNP transistor TR1 is turned on. As a result, the electric charge accumulated in the electric double-layer capacitors C3 and C4 is supplied to the light emitting diode LED1 via the PNP transistor TR1 and the constant current circuit 3 to turn on the light emitting diode LED1. While the light emitting diode LED1 is on, the position of the distribution board can be immediately known even in the dark, and inspection and return work can be performed. The constant current circuit 3 protects the light emitting diode LED1 from destruction due to an overcurrent caused by being rapidly discharged from the electric double layer capacitors C3 and C4, and plays a role of lighting the light emitting diode LED1 at a constant luminance for a long time. I have.
[0016]
When power is restored, the base voltage of the PNP transistor TR1 rises again and turns off, turning off the light emitting diode LED1 and charging the electric double layer capacitors C3 and C4.
[0017]
The circuit thus configured is mounted on a printed circuit board, housed in a resin case 4 as shown in FIG. 2, and provided on a residential distribution board 5 and the like. As shown in FIG. 3, a plurality of branch breakers 8 are arranged side by side on the upper and lower sides of a main distribution bar 5 so as to sandwich a main bar 7 arranged to extend rightward from the main breaker 6, as shown in FIG. Are connected to one end of the main bar 7 by a connection bar 9. As shown in FIG. 2, the security light 1 for power failure is installed on the front surface of the resin cover 10 covering the connection bar 10, and is connected to the load side terminal 6 a of the main breaker 6 to the terminal portions P 1 and P 2 of the security light 1 for power failure. It is used by connecting the electric wire 11. The light-emitting diode LED1 is provided on the front surface of the case 4 of the power failure security light 1, and is arranged so that the light-emitting diode LED1 is exposed from the front cover 12 of the residential distribution board 5 as shown in FIG.
[0018]
For this reason, the light-emitting diode LED1 of the security light 1 for power failure illuminates the vicinity of the handle of the breaker or the limiter at the time of power failure, which facilitates inspection and return work. Also, it does not interfere with wiring in the distribution board.
[0019]
In this embodiment, two electric double-layer capacitors are used. However, the number of electric double-layer capacitors is not limited to two, and may be one or three or more. At this time, when using two or more electric double layer capacitors, the Zener diode is connected in parallel with the electric double layer capacitor.
[0020]
【The invention's effect】
As described above, according to the first aspect of the invention, in a power failure safety light that illuminates the periphery of a distribution board when a power failure occurs, the power supply of the lamp is configured by an electric double-layer capacitor. Since no batteries are used, there is no need for replacement, there is no problem of environmental pollution due to battery disposal, and there is no need for a test circuit for checking the remaining battery level. In addition, since it can be miniaturized, it can be installed between the connection bar and the front cover of the distribution board when it is installed on the distribution board, so that it does not interfere with wiring to the breaker, etc. There is an effect that the effective space is not reduced.
[0021]
