Is attached.

FIG. 1 shows a control circuit of the power failure lamp device incorporated in the power failure lamp body 3a. here,
A nickel cadmium battery (internal power supply) 14 is connected to the connection plug part 8 of the power failure lamp body 3a via a transformer 10, a rectifier circuit 11, a backflow prevention diode 12, a light emitting diode of the charging display part 7, and a resistor 13. There is. A control unit 15 formed by, for example, a microcomputer and its peripheral circuits is connected to the nickel-cadmium battery 14.

An antitheft buzzer 18 is provided in the power failure lamp body 3a. A lamp drive circuit 16 for the lamp 5 and a buzzer drive circuit 17 for an anti-theft buzzer 18 are connected to the controller 15.

Further, an outlet switch 9 and an on / off switch 6 are connected to the control unit 15, and
Reset circuit 19, forced reset switch 20, clock circuit 21, power interruption detection circuit (power interruption detection means) 2
2 are connected to each other.

Here, the outlet switch 9 has a push button 9a which is capable of projecting and retracting to the outside of the power failure lamp body 3a, and a return spring (not shown) which urges the push button 9a in a direction of projecting the push button 9a to the outside of the power failure lamp body 3a. Is provided. When the power failure lamp 3 is inserted into the outlet 2, the push button 9a is pushed by the outlet plate 2a and resists the spring force of the return spring.
When the power failure lamp 3 is held in the ON state by being pushed into the power outlet a and the power failure lamp 3 is pulled out from the outlet 2, the push button 9a is projected to the outside of the power failure lamp body 3a by the spring force of the return spring. The switch 9 is turned off to detect the plugging / unplugging state of the power failure lamp body 3a and the outlet 8.

The reset circuit 19 and the forced reset switch 20 are connected to the reset terminal of the controller 15. Then, when the charging voltage of the nickel-cadmium battery 14 exceeds the set value, the reset circuit 19 causes the control unit 1 to
A reset signal is output to the reset terminal of No. 5. The forced reset switch 20 is disposed inside the housing of the power failure lamp body 3a, and the forced reset switch 20 cannot be turned on unless the housing of the power failure lamp body 3a is opened.

The power cutoff detection circuit 22 detects a power cutoff state in which the power supply to the external power source side connected to the power failure lamp body 3a via the outlet 2 is cut off.
That is, when there is an output from the rectifier circuit 11, the transistor of the power cutoff detection circuit 22 is turned on, a low level signal is input to the input terminal of the control unit 15, and the output from the rectifier circuit 11 is cut off. When the transistor of the power cutoff detection circuit 22 is turned off and a high level signal is input to the input terminal of the control unit 15, the power cutoff state is detected.

Next, the operation of the above configuration will be described with reference to the flowcharts of FIGS. 4 and 5. First, when the plug blade 8a of the power failure lamp 3 is inserted into the outlet 2, it is determined whether to set or reset the power shutoff / theft determination flag in the control unit 15 (step S1). In this way, when the plug blade 8a of the power failure lamp 3 is inserted into the outlet 2, the outlet switch 9 is held in the ON state.

When the reset state of the power shutoff / theft discrimination flag is detected, the lamp 5 of the power failure lamp body 3a is held in the off state (S2), and the nickel-cadmium battery 14 is charged ( S3). During this charging, the light emitting diode of the charging display unit 7 is turned on and the state thereof is displayed.

Further, it is judged whether or not the charging voltage of the nickel-cadmium battery 14 has reached a set value or higher (S
4) After the state where the charging voltage has reached the set value or higher is detected, the power shutoff / theft determination flag is reset (S5). Here, when the state where the charging voltage has reached the set value or higher is not detected, the charging of the battery 14 is repeated.

Next, it is determined by the power cutoff detection circuit 22 whether the external power supply is shut off or the outlet switch 9 is turned on (S6). Here, outlet switch 9
ON state is detected (power failure lamp 3 in outlet 2
When the power cutoff state of the external power supply is detected by the power cutoff detection circuit 22 in the state of (plugged in), it is determined as a power failure state (S7).

At the time of determining the power failure state, the OFF state of the outlet switch 9 is subsequently determined (S8). Here, when the OFF state of the outlet switch 9 is not detected, the lamp 5 of the power failure lamp body 3a is held in a lighting state (S9).

In step S6, if the power cutoff detection circuit 22 does not detect the power cutoff state of the external power source and the ON state of the outlet switch 9, then the power cutoff detection circuit 22 cuts off the external power source. And the outlet switch 9 is turned off (S1).
0). Here, if the power cutoff state of the external power source and the off state of the outlet switch 9 are not detected by the power cutoff detection circuit 22, steps S1 to S6 and S10 are repeated.

If the outlet switch 9 is turned off when the external power source is energized in S10 and the power source shutdown state of the external power source is detected by the power source shutdown detection circuit 22, it is determined that the power source is stolen (S11). .

At the time of determining the stolen state, a power shutoff / theft determination flag in the control unit 15 is set (S1).
2). Further, with this flag set, the process returns to step S1. Therefore, in this case, since the flag set state is detected in S1, the antitheft buzzer 18 in the power failure lamp body 3a is turned on and sounded (S13).
At the same time, lighting of the lamp 5 by the on / off switch 6 is prohibited (S14).

Further, after the theft process of performing the ringing operation of the buzzer 18 in S13 and the operation of prohibiting the lighting of the lamp 5 in S14, the ON state of the reset switch 20 is determined (S15). Here, when the on-state of the reset switch 20 is not detected, the on-state of the outlet switch 9 is subsequently determined (S16). When the ON state of the outlet switch 9 is not detected, the process returns to step S1. Therefore, when the power failure lamp body 3a is pulled out from the outlet 8 when the external power source is energized, the buzzer 18 sounds and the lamp 5
The stolen state in which the lighting of is prohibited is retained.

Further, after the theft processing is performed, S15
When the ON state of the reset switch 20 of is detected,
Alternatively, if the ON state of the outlet switch 9 is detected in S16 (the power failure lamp 3 is returned to the outlet 2), the power shutoff / theft determination flag in the control unit 15 is reset (S17). And the anti-theft buzzer 18
Is turned off to stop the ringing (S18), the prohibition of lighting the lamp 5 by the on / off switch 6 is released (S19), and then the process returns to the step S1.

Further, when the OFF state of the outlet switch 9 is detected in step S8, the power failure lamp 3 is pulled out from the outlet 2 and it is determined that the power failure lamp 3 is used as a flashlight. In this case, the pressed state of the on / off switch 6 is subsequently determined (S20).

Here, when the pressed state of the on / off switch 6 is not detected, the timer is started and the time counting is started (S21). Then, after the timer is started, it is determined that a predetermined set time t ₂ has elapsed (S22), and an appropriate set time (t ₂ −x) before the set time t ₂ has elapsed is determined. The state that has passed is determined (S23).

[0031] Then, the lamp 5 of the blackout lamp body 3a is switched operated blinking state when it is detected that the state has elapsed _{(t 2 -x) (S24)} . Then, the pressed state of the on / off switch 6 is determined (S25). Here, when the pressed state of the on / off switch 6 is not detected, the process returns to S22, and when the pressed state of the on / off switch 6 is detected, the lamp 5 of the power failure lamp body 3a is switched to the continuous lighting state. (S26). Further, after the lamp 5 of the power failure lamp body 3a is switched to the continuously lit state, it is held in a normal use mode state as a flashlight in which the lamp 5 can be switched on and off by operating the on / off switch 6. (S2
7).

In step S20, the on / off switch 6
When the pressed state of is detected and in step S22,
After the timer is started, the power failure lamp body 3 is detected when a state in which an appropriate preset time t ₂ has elapsed is detected.
The lamp 5 of a is turned off (S28). Therefore, it is prevented that the power failure lamp 3, which is determined to be used as a flashlight, is continuously lit for the set time t ₂ or more and the nickel cadmium battery 14 is consumed. The blackout lamp 3 used as a flashlight is used as the blackout lamp 3 after being used by being plugged into the outlet 2 again.

Therefore, in the case of the above-mentioned structure, the guest or the like tries to take out the power failure light 3 without permission during normal times when the power failure light 3 plugged into the outlet 2 is energized by the external power source. , (B) as shown in FIG.
When the battery is pulled out from the outlet 2, the buzzer 18 is turned on and is sounded, and the lamp 5 is held in a non-lightable state. Since the switch for stopping the buzzer 18 is not provided outside the housing of the power failure lamp body 3a, it keeps ringing until the power failure lamp body 3a is inserted into the outlet 2.

At this time, the caution label 10 affixed to the outlet 2 "Do not remove from the outlet except when there is a power failure." The buzzer sounds when you pull it out. By letting the guest who tried to take out the power failure light 3 without permission, the power failure light body 3a can be reinserted into the outlet 2 to stop the buzzer 18,
It is possible to prevent the power failure lamp 3 from being stolen. Therefore, it is possible to prevent the power failure light 3 from being taken out from the room of the accommodation facility and held in a state where it is not installed as in the conventional case, so that the guest does not have a problem when a power failure occurs.

Further, the power failure lamp 3 inserted into the outlet 2 is not energized by operating the on / off switch 6 even if the power switch lamp 6 is operated while the power failure lamp main body 3a is pulled out from the outlet 2 during normal operation when the external power source is energized. Therefore, it cannot be used as a flashlight, and the customer gives up taking it out. Therefore, it is possible to effectively prevent the power outage light 3 from being stolen, so that there is an economic advantage that the owner of the inn, the lodge, or the like having the power outage light 3 does not have to replenish the power outage light 3 due to the theft. .

Further, when the power failure lamp 3 inserted into the outlet 2 is cut off from the external power supply, or when the breaker is cut off, the control section 15 determines the power failure state, and the lamp 5 of the power failure lamp body 3a is instantaneously operated. Since it is automatically turned on, the inside of the accommodation room does not become dark and the guest can act calmly. At this time, the buzzer 18 does not sound even if the power failure lamp 3 inserted into the outlet 2 is pulled out, and it can be used as a flashlight by operating the on / off switch 6, which is useful in an emergency such as a power failure.

The present invention is not limited to the above embodiment. For example, in the above embodiment, the power failure lamp 3 which is determined to be used as a flashlight is set for the set time t ₂
The structure having the function of preventing the nickel cadmium battery 14 from being continuously lit and exhausting the nickel cadmium battery 14 has been described above. However, this does not need to be specially provided, and the power failure lamp main body 3a can be configured by omitting it. Good.

Further, it goes without saying that various modifications can be made without departing from the scope of the present invention.
