DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency guide light for safely guiding an evacuated person when an emergency such as an earthquake occurs.

[0002]

2. Description of the Related Art Lighting equipment using solar cells called Lumitile (trade name) has been commercialized. FIG. 7 shows the specific structure. In FIG. 7, reference numeral 20 denotes a bottomed box provided with a flange portion 21, in which a storage battery 22, a light emitting body 23 composed of a combination of an LED and a reflecting mirror, a light emission control circuit 24, and a solar cell 25 are provided. Are housed, and they are covered with a translucent window plate 26 made of tempered glass or the like.

[0003] The Lumitile is embedded in a road surface or a wall of a park or the like, and the electric power generated by the solar cell 25 is stored in the storage battery 22 in the daytime. It is used for various displays outdoors, such as road signs, destination guidance, and various other illuminations.

[0004]

Generally, in a place where a lot of people gather, such as a hotel or a meeting place, in the event of an emergency such as a fire or an earthquake, an emergency guide light for guiding those people to a safe place is provided. Installation is mandatory. The configuration of the basic emergency guide light is to always charge the storage battery from the AC power supply, and to turn on the guide light for a certain period of time with the power from the storage battery even if the AC power supply goes down in the event of an emergency, to try to guide the evacuation. Things.

[0005] In addition, even in the vicinity of an exit of a meeting hall or outdoors such as a park, it is necessary to guide the user to a safe place in the event of an emergency. The need is particularly high at night.

However, since it is difficult to obtain AC power in the outdoors compared with indoors such as a meeting place, it is necessary to provide special wiring, and there is no legal regulation. Has not been done.

On the other hand, the Lumitile shown in FIG. 7 does not require an AC wiring because it uses electric power generated by a solar cell. However, since this Lumitile is made mainly for decoration at night, it emits light. Brightness is not so high, so as to light a faint light for a long time,
It is configured, and can hardly expect the function of evacuation guidance in the event of an emergency.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and turns on power from a storage battery storing power generated by a solar cell when an emergency occurs. The emergency light is supplied to the emergency light emitter for displaying an instruction for evacuation guidance via the emergency switch.

[0009]

According to the present invention, it is possible to guide evacuation in the event of an emergency even in the outdoors where it is difficult to obtain AC power.

Thus, when an earthquake occurs and a certain degree of vibration, for example, with a seismic intensity 3 or more is applied to the hard sphere 6,
The hard sphere 6 vibrates while being attached to the coil spring 7, and comes into contact with an electric contact 8 provided around the coil spring 7 to be turned on.
A signal is sent to the state holding circuit 9 to turn on the emergency switch 5.

Returning to FIG. 1, reference numeral 10 denotes an emergency light emitter composed of a high-brightness LED, a halogen lamp, and the like, which is connected in series to the storage battery 2 via a light / dark switch 4 and an emergency switch 5. ing. And this luminous body 1
As shown in FIG. 3, 0 indicates characters such as an arrow indicating a direction in which evacuation can be safely performed in the event of an emergency or a safety direction.

The circuit structure shown in FIG. 1 is assembled as shown in FIG. 4 and, like the Lumi tile shown in FIG.
For example, in the daytime, it is embedded in the promenade of a park where sunlight is often irradiated.

When an earthquake having a seismic intensity of 3 or more occurs at night, the emergency switch 5 is turned on as described above. Therefore, the power of the storage battery 2 is transmitted through the switch 5 and the light / dark switch 4 which is already turned on. Is supplied to the emergency luminous body 10 to light up. And by escaping in a safe direction guided by the lighting, it is possible to evacuate safely. In the event of an earthquake, there is a possibility that the power supply is cut off and the evacuation direction is not known at all, and there is a risk of falling into a panic state. Will.

[0015] Figure 5 shows an electrical circuit diagram of a real施例incorporated into existing Rumitairu showing the present invention emergency guide lamp 7, the same reference numerals are assigned to the same as FIG. 1, Description is omitted. In FIG. 5, reference numeral 11 denotes a light / dark switch 4.
