It has a hysteresis characteristic in which current conduction occurs at the resistance operating point. In the emergency light configured as described above, during general use, the regular lighting lamp 1 operates and the fluorescent lamp 1 lights up when the commercial power is turned on, and when the commercial power is turned off, the regular lighting lamp 1 stops operating. Normally closed contact 1 of relay 11 in the emergency light main circuit
2 is closed, contacts 13 and 14 are switched, and the transistor inverter 10 turns on the fluorescent lamp 1 to provide emergency illumination. When checking the function of the storage battery 9, check at time T in FIG. A commercial power outage is artificially caused in the circuit by, for example, opening the inspection switch 4. When a commercial power outage occurs, the transistor inverter 10 connects the storage battery 9 via the contact 12.
As the storage battery 9 discharges, the voltage V across both ends increases.
As B decreases, the low operating point V of the lambda diode 20
. The divided voltage V across the resistor 16 at a voltage higher than
l6 also decreases as shown in FIG. Even after a certain period of time, for example 20 minutes, the divided voltage Vl6 remains at the low operating point V. , the storage battery 9 has a normal capacity, and in that case, the lambda diode 20 maintains a current blocking state, the transistor 19 is non-conducting, no current flows to the light emitting diode 18, and the display is not displayed. Not done. Next, fixed time T2? Among them, for example, as shown in FIG. 4, the divided voltage V]6 at time t1 is the low operating point V. If it becomes lower than , the storage battery 9 does not have a normal capacity, and in that case, the lambda diode 20 which was in the current blocking state changes to the current conducting state, and the base current is supplied to the transistor 19. The light emitting diode 18 becomes conductive and current flows through the light emitting diode 18, and the light emitting diode 18 emits light, indicating that the voltage of the storage battery 9 has fallen below a predetermined voltage at time T2. Then, at time T2, the artificial commercial power outage is canceled, and the storage battery 9 is charged through the charging circuit to reach the required voltage, and the divided voltage Vl6 also reaches the required voltage and maintains its level. That is, once the low operating point voltage V. The lambda diode 20, which has entered a current conduction state due to the following conditions, does not enter a current blocking state because the applied voltage does not exceed the high operating point voltage V1, and the light emission of the light emitting diode 18 is maintained by maintaining conduction of the transistor 19. However, the state of the storage battery 9 after a certain period of time for battery inspection is memorized and displayed as is. After checking the display, close the reset switch 23 momentarily and connect the resistor 2 in series with the lambda diode 20.
By effectively shorting 1, the lambda diode 20 can be returned to a current blocking state, rendering the transistor 19 non-conducting and deactivating the display of the light emitting diode 18. Next, if you forget to connect the storage battery 9,
A pulsating voltage is applied to the terminals to be connected, and the voltage Vl6 across the resistor 16 also becomes a pulsating voltage as shown in FIG.

At this time, the peak value of the pulsating voltage Vl6 is set to the high operating point voltage V1
By choosing a lower value, the lambda diode 20 maintains the current conduction state, and the conduction of the transistor 19 causes the light emitting diode 18 to emit light and maintain the display. Therefore,
It is possible to know if the storage battery 9 has been forgotten to be connected. Next, during normal use, if an abnormal temperature rise occurs in the emergency lighting equipment due to a failure of an electrical component, such as a partial short circuit of the check coil 2, a positive characteristic heat sensitive resistor for voltage division is installed in the battery checker. The resistance value of the resistor 15 gradually increases as the temperature rises, and as a result, the voltage divided across the resistor 16 becomes smaller, so that even if the voltage of the storage battery 9 is at a normal value, the voltage V1 is at a low operating point V.
