If it is open, the indicator light 10 is properly turned off. However, the indicator lamp 10 is not turned off in a short circuit. The storage battery 7 is an assembled battery, and does not turn off even when some of the cells are in a short-circuit state. Even if there is an abnormality in the connector 25 of the storage battery 7 and its polarity is short-circuited, it does not turn off. For example, the light does not turn off when an incompatible storage battery 7 such as an assembled battery having an unspecified number of cells is connected. Furthermore, even when the indicator light 10 is turned off, there is a problem that it is not immediately known whether the abnormality is caused by the abnormality of the storage battery 7 charging circuit or the emergency light 21 circuit.

Here, the component codes in FIG. 3 are used as much as possible, and the overlapping description will be omitted as appropriate. The illustrated emergency light lighting device includes a charging transformer 3 that transforms the voltage of the commercial power supply 1. A rectifier 4 for rectifying the output of the charging transformer 3 is provided. It has a storage battery 7 which receives the output of the rectifier 4 via the charging resistor 6 and is charged. A power failure detection relay 2 including a normally closed contact 32 that opens when the commercial power supply 1 fails and a normally open contact 31 that closes when the power failure occurs. A comparison / determination circuit mainly including a comparator (including 1/2 and 2/2) 9 for detecting a charging voltage at the time of charging the storage battery 7 and comparing whether or not the voltage is within a normal charging voltage range is provided. An indicator light 20 is provided for notifying an abnormality when the voltage is outside the normal charging voltage range. Supplement the explanation of the configuration. The lower reference value of the comparator 9 is the Zener diode 8
And the upper reference value is the Zener diode 1
Given by 4. Reference numerals 15 and 22 denote resistors for supplying power to the Zener diodes 14.8. The range of the upper and lower limit reference values is as shown in VBL · VBH in FIG. The charging voltage of the battery 7 changes, for example, as indicated by a solid line Q.
It falls within the range of BL · V BH . The output of the comparator 9 (1/2 and 2/2) is given to the indicator lamp 10 via the diodes 11 and 12. Indicator light 10 is a light emitting diode. The output voltage of the rectifier 4 is applied to the indicator lamp 20 via the resistor 13. The driving power supply circuit of the comparator 9 includes a resistor 16, an electrolytic capacitor 18, and a Zener diode 19. Reference numeral 10 denotes an indicator lamp that lights up and notifies when the circuit of the emergency lamp 21 is normal. The indicators 10 and 20 are light emitting diodes. In the circuit shown in FIG. 1, when the commercial power supply 1 is operating normally, a charging current is supplied to the storage battery 7 via the charging resistor 6 and the normally closed contact 32. 2, the charging voltage Q inputted to the minus terminal (-) of the comparator 9 (1/2) is the upper limit reference voltage inputted to the plus terminal (+). (Zener diode 14 voltage) Since it is lower than VBH , the output becomes H.
On the other hand, the comparator 9 (2/2) charging voltage Q thereof negative terminal input to the positive terminal (+) of the - higher than the lower limit reference voltage input to (zener diode 8 voltage) V BL, () The output becomes H. Thus, the comparator 9 (1
/ 2) Both outputs of (2/2) become H, and the indicator lamp 20 is turned on. This is a notification of a normal state. Next, consider an abnormal time. When the connection of the connector of the storage battery 7 is forgotten, when the inappropriate storage battery 7 is used, or when the storage battery 7 is in the short mode or the open mode, the charging voltage of the storage battery 7 is out of the normal charging voltage range. . If the charge voltage of the storage battery 7 is too high, the charge voltage input to the minus terminal (-) of the comparator 9 (1/2) is higher than the upper limit reference voltage input to the plus (+) terminal. VBH and the comparator 9 (1 /
2) The output becomes L. For this reason, the voltage of the indicator lamp 20 connected via the diode 12 also becomes L, and turns off to notify an abnormality. If the charge voltage of the storage battery 7 is too low, the charge voltage input to the plus terminal (+) of the comparator 9 (2/2) is lower than the lower limit reference voltage input to the minus (−) terminal. V BL , the comparator 9
(2/2) The output becomes L. Therefore, the diode 11
The voltage of the indicator lamp 20 connected via the switch also becomes L, turns off the light, and notifies an abnormality. When the emergency light 21 circuit is normal when the commercial power supply 1 is supplied, 4-17-10-21-
4 is established, and another indicator light 10 is turned on. This is a normal announcement. If the emergency light 21 is disconnected or the connection is poor, the closed circuit is broken and the indicator light 10 is turned off to notify an abnormality. Therefore, the indicator lamp 10
By comparing 20, it can be determined whether there is an abnormality on the storage battery 7 side or a problem on the emergency light 21 side.
The significance of the present invention will be supplemented. For example, consider a situation in which the storage battery 7 whose life has expired is being charged. In the case of the apparatus shown in FIG. However, if left as it is, there is a risk of heat generation and rupture. In the case of FIG. 1, another indicator light 20 is turned off to notify an abnormality.
