Abstract

PROBLEM TO BE SOLVED: To avoid confusion in an emergency, as during power outages or when fires are detected. SOLUTION: A battery 4 is connected to an emergency light 3 via a changeover switch SW2 and a sound/voice generator 2 is connected to the battery 4 via a switch SW 1 which has a normally open contact. Messages showing the direction of evacuation or messages urging people to behave calmly are prestored in the sound/voice generator 2 in the form of synthetic voices, etc., and when an emergency such as fires is detected by an emergency detection circuit 1, the switch SW 1 is controlled to put the sound/voice generator 2 and the battery 4 into conduction to each other. Therefore the sound/voice generator 2 is actuated to issue buzzer sounds and to issue the synthetic voices as the messages urging people to behave calmly. Thus even if the evacuation route display of the emergency light 3 is hard to see because of smoke, etc., the messages are given in the form of voices to allow the people to precisely recognize the evacuation route and to urge them to behave calmly to avoid confusion.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency lighting device that lights when an abnormality occurs, such as when a power failure occurs or a fire is detected.

[0002]

2. Description of the Related Art Conventionally, an emergency lighting device is lit when, for example, a power failure occurs or when a fire is detected. For example, the emergency lighting device acts as a guide light or displays an evacuation direction so that the evacuation direction can be changed. You can be notified.

[0003]

However, for example, in the case of a power failure due to a fire or the like, even if the emergency lighting device is activated, the visibility becomes poor when smoke is full, and the location of the emergency exit cannot be determined. There is a problem that it is difficult to evacuate due to lack of sense of direction.

[0004] Further, when a fire or the like occurs, it is easy to fall into a panic state. For example, there is a case where an artificial accident occurs due to a flood in an emergency exit or the like. Measures were desired.

Accordingly, the present invention has been made in view of the above-mentioned conventional unsolved problems, and it is possible to prevent the occurrence of confusion at the time of occurrence of an abnormality, such as confusion at the time of evacuation due to the occurrence of an abnormality. It is intended to provide an emergency lighting device.

[0006]

In order to achieve the above-mentioned object, an emergency lighting device according to the present invention is an emergency lighting device which is lit at least when an abnormality is detected by abnormality detecting means. A sound generating means for generating a sound when an abnormality is detected by the means.

According to the present invention, when an abnormality is detected by abnormality detection means such as a temperature sensor, a smoke sensor, and a power failure detection sensor, the emergency lighting device is turned on, and a buzzer sound is generated by the sound generation means. Or a message by synthesized voice or the like is announced. Therefore, for example, by announcing a message in the evacuation direction by sound using the sound generating means, it is possible to accurately recognize the evacuation route even when the evacuation direction is unknown due to, for example, smoke or the like, or by voice. By encouraging cool behavior, the occurrence of confusion is avoided.

[0008]

Embodiments of the present invention will be described below. FIG. 1 is a schematic configuration diagram showing an example in which the emergency lighting device according to the present invention is applied to an indicator light provided at an emergency exit and clearly indicating “emergency exit”.

The emergency lighting device 10 is provided with, for example, a temperature sensor, a smoke sensor, or a power failure detection sensor for detecting whether or not power is supplied to the room, thereby detecting whether or not a power failure has occurred. An abnormality detection circuit 1, a sound / sound generator 2 for generating a buzzer sound or sound, and an emergency light 3
And a battery 4 for operating the sound / sound generator 2 and the emergency light 3 and a DC power supply 5 for converting an AC power supply to a DC power supply. The sound / sound generator 2 has normally open contacts. Connected to the battery 4 via the switch SW1,
The emergency light 3 is connected to the battery 4 and the DC power supply 5 via the changeover switch SW2.

The abnormality detection circuit 1 detects that a fire has occurred when the detection value of the temperature sensor or the smoke sensor has exceeded a predetermined value, or that the power supply to the room has been stopped by the power failure detection sensor. Is detected, the switch SW1 is controlled to be closed as an occurrence of an abnormality, and the switch SW1 is controlled to be opened when it is detected that the abnormality has been released based on the detection status of each sensor. When the switch SW2 is controlled to detect that power is being supplied to the room by a power failure detection sensor (not shown), the DC power supply 5 and the emergency light 3 are brought into conduction, and the power failure is detected. When a power failure is detected by the sensor, the battery 4 and the emergency light 3 are brought into conduction.

The sound / voice generator 2 is a generator capable of generating a buzzer sound or announcing a message by voice. When the switch SW1 is closed, the sound / voice generator 2 and the battery 4 are electrically connected. In the state, while the power is being supplied, a buzzer sound, a message created and stored in advance by synthetic speech, or a message recorded in advance, for example, is generated alternately. As this message, for example, a message instructing an evacuation direction or a message urging a cool action is announced.

The emergency light 3 includes a display panel (not shown) on which characters "emergency exit" are displayed.
By turning on the emergency light 3, the characters "emergency exit" on the display panel are clearly indicated.

Next, the operation of the above embodiment will be described.
When a fire or the like occurs in a state where the emergency light 3 is turned on by the power supplied from the DC power supply device 5, the abnormality detection circuit 1 detects the fire by its temperature sensor or smoke sensor. When detecting a fire, the abnormality detection circuit 1 controls the switch SW1 to a closed state. This allows
The battery 4 and the sound / voice generator 2 are brought into conduction, and the sound / voice generator 2 is activated to generate a buzzer sound and announce a pre-stored synthesized voice message.

When a power failure is detected by the abnormality detection circuit 1, the changeover switch SW2 is controlled to connect the battery 4 and the emergency light 3 instead of the DC power supply device 5. When a power failure occurs, the emergency light 3 is turned off because power cannot be supplied from the DC power supply 5 to the emergency light 3, but the emergency light 3 is continuously turned on because the battery 4 is switched.

Therefore, even if a power failure occurs, the emergency light 3 is continuously lit, and even if the fire is filled with smoke and visibility becomes poor, and the sense of direction is lost, the sound /
Since the voice generator 2 notifies the evacuation direction, the evacuation can be performed quickly. In particular, for visually impaired persons and the like, the synthesized voice by the sound / voice generator 2 is effective instead of a so-called passage guide light.

At this time, when the sound / voice generator 2 gives a caution to act calmly,
It is possible to prevent a situation such as a panic caused by a fire or the like and a confusion state.

Further, since the sound / voice generator 2 uses the battery 4 for the emergency light 3, a new sound / voice is generated.
This can be realized without providing a battery for the sound generator 2.

In the above-described embodiment, a case has been described in which the sound / sound generator 2 generates a buzzer sound or a synthesized sound when the abnormality detection circuit 1 detects an abnormality. The sound / sound generator 2 may be provided with a smoke sensor, and when the detection value of the smoke sensor exceeds a value that can be regarded as being full of smoke, the sound / sound generator 2 may be activated. Good. In other words, while the smoke is small and the visibility is relatively good, guidance is provided by the emergency light 3, and when the smoke is full and the visibility deteriorates, the sound / voice generator 2 is generated. The battery 4 can last a long time, which is effective.

Further, in the above embodiment, the case where a power failure detection sensor, a temperature sensor, a smoke sensor, and the like are provided as the abnormality detection circuit 1 has been described. However, the present invention is not limited to this. You may. Also,
Any one or more of these sensors may be provided.

In the above embodiment, the case where the buzzer sound and the synthesized voice are generated alternately has been described. However, the present invention is not limited to this. For example, only the buzzer sound or only the synthesized voice is generated. It may be. In addition, a chime may be used instead of the buzzer sound. Alternatively, the buzzer sound may be generated at a volume that does not reverberate, and the buzzer sound may be guided more randomly.

In the above embodiment, the case where the present invention is applied to an emergency light indicating an emergency exit has been described. However, for example, a fire alarm, a passage guide light, or an emergency lighting device which is turned on at the time of a power failure, etc. The sound / speech generator 2 may be incorporated.

Further, in the above-described embodiment, the case has been described where the emergency light 3 is always turned on by using the DC power supply 5 and the battery 4, but the present invention is not limited to this. When a power failure is detected in step 1, the battery 4 and the emergency light 3 may be in a conductive state, and the emergency light 3 may be turned on only at the time of the power failure.

[0023]

As described above, according to the emergency lighting device according to the present invention, the emergency lighting device is turned on when the abnormality is detected by the abnormality detecting means, and the buzzer sound, the synthesized voice, etc. are generated by the sound generating means. Since the sound is generated, for example, the sound generation means notifies the evacuation direction by voice, or by notifying to act calmly, etc., it is possible to accurately recognize the evacuation route and quickly evacuate,
The occurrence of confusion can be avoided.
