本発明は停電時に非常灯を点灯させるための非
常灯点灯装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an emergency light lighting device for lighting emergency lights during a power outage.
実開昭49−28977号公報に蓄電池のための充電
回路中に、非常灯と表示灯をそれぞれ直列に接続

Japanese Utility Model Application No. 49-28977 discloses an emergency light lighting device in which an emergency light and an indicator light are connected in series in a charging circuit for a storage battery.
これによれば、蓄電池の充電がなされ、かつ非
常灯が正常であるときに表示灯が点灯する。した
がつて、この表示灯が充電表示を含む総合的なチ
エツク灯として機能するので便利である。 According to this, the indicator light is turned on when the storage battery is charged and the emergency light is normal. Therefore, this indicator light conveniently functions as a comprehensive check light including a charging indicator.
しかし、表示灯が不点灯であるにもかかわら
ず、何らかの事情で相当の期間にわたり放置され
ることがあるが、このような場合に次のような問
題を生ずる。 However, even though the indicator light is not lit, it may be left unlit for a considerable period of time for some reason, and in such a case, the following problems occur.
すなわち、蓄電池への充電停止中に自然放電に
よつて蓄電量が低下し、そのためにいざというと

万全を期するためにせつかく加えた表示灯の断線
あるいは装着不備が原因である場合はとくに耐え
難い。 That is, while charging to the storage battery is stopped, the amount of stored electricity decreases due to natural discharge, which makes it useless in an emergency, and it takes time to recover the charge. Therefore, this becomes a factor in reducing reliability. In particular,
It is especially difficult to endure when the cause is a disconnection or improper installation of the indicator light, which was added to ensure complete safety.

The present invention strengthens the check function so that it displays not only the status of the storage battery and emergency lights, but also the status of the relay for power outage detection. This device is designed to ensure that the battery is continuously charged.

In the present invention, in addition to a normally closed contact for lighting an emergency light that opens during operation and closes during a power outage, a relay for power failure detection is used that has a normally open contact that closes during operation and opens during a power outage. Then, an indicator light is connected in parallel to the charging resistor via the latter normally open contact and an emergency light.

常開形接点と非常灯を介して表示灯に印加し、表
示灯が点灯する。これは正常な状態である。 Under power supply conditions before a power outage, charging current is supplied to the storage battery via the charging resistor even if the indicator light circuit connecting the indicator light, normally open contact, and emergency light is disconnected. Further, the voltage across the charging resistor is applied to the indicator light via the normally open contact and the emergency light, and the indicator light turns on. This is a normal condition.
この状況下で表示灯が消灯する主な原因は充電
電流の供給停止、非常の断線ないしは装着不良、
リレーの動作不良である。表示灯が現に消灯した
場合は故障と判定する。 The main causes of the indicator light going out in this situation are charging current supply interruption, emergency wire breakage, or improper installation.
The relay is malfunctioning. If the indicator light actually goes out, it is determined that there is a failure.
上記の常開形接点はノーマルオープン形のＡ接
点、常閉形接点はノーマルクローズ形のＢ接点を
意味するが、停電しない給電状況下（リレー動作
状況）を常々の状態とするのであれば常開、常閉
の関係は逆転する。 The above-mentioned normally open type contact means normally open type A contact, and normally closed type contact means normally closed type B contact, but if the power supply condition without power outage (relay operation condition) is to be used as usual, normally open type contact is used. , the normally closed relationship is reversed.

The embodiment of the present invention shown in FIG. 1 will be described below. The emergency light lighting device of this embodiment includes a storage battery 2 that is charged via a charging resistor 9, and a normally closed contact 51 that opens during operation and closes during a power outage, and a normally open contact 52 that closes during operation and opens during a power outage. A relay 4 for detecting a power outage is provided, an emergency light 3 is connected in parallel to the storage battery 2 via a normally closed contact 51, and is connected in parallel to a charging resistor 9 via a normally open contact 52 and the emergency light 3. The display lamp 1 is provided with an indicator light 1. The indicator light 1 is a light emitting diode.

ある。 Among the components other than those mentioned above, 6 is a charging transformer that steps down the commercial power supply V, and 8 is a rectifier that rectifies its secondary output. Reference numeral 7 denotes an inspection switch that temporarily stops power supply from the commercial power supply V during inspection. 10
is a current adjustment resistor connected in series with the indicator lamp 1.

て表示灯１に印加し、これが点灯する。 When the commercial power supply V supplies power, the storage battery 2 is charged via the charging resistor 9 . At this time, a voltage is generated across the charging resistor 9. This voltage is applied to the indicator light 1 via the emergency light 3, the normally open contact 52, and the resistor 10, and the indicator light 1 is turned on.

の場合も同様である。 The above is the basic operation under normal conditions, but if there is a failure factor such as a disconnection of the emergency light 3, a poor contact between its base and socket, or a poor connection of the storage battery 2, the indicator light 1 will not light up. Furthermore, the same applies when the relay 4 does not operate and the normally open contact 52 remains open.

このため、蓄電池２により非常灯３は点灯する。 Next, the situation during a power outage will be explained. The operation of the relay 4 is stopped due to a power outage or a forced cutoff by the inspection switch 7. Therefore, the normally closed contact 51 of the relay 4 is switched to its original closed state.
Therefore, the emergency light 3 is turned on by the storage battery 2.
