Description

[0001] The present invention relates to a portable emergency lighting apparatus having an emergency situation guidance function,

The present invention relates to a portable emergency lighting apparatus having an emergency situation guidance function, and more particularly, to a portable emergency lighting apparatus having a function of detecting an emergency situation such as flooding, leakage, fire and power outage at a place where a portable emergency lighting apparatus is disposed, And more particularly, to a portable emergency lighting apparatus having an emergency situation guide function for guiding an emergency situation through voice.

Portable emergency lights are installed and operated in designated places such as accommodation, department stores, underground shopping malls, and underground history in accordance with the installation standard of portable emergency lighting of fire-related laws and ordinances.

The conventional portable emergency lighting lamp is composed of a cradle fixedly arranged at an installation place, a portable lantern which is detachably mounted on the cradle, a battery is provided therein and a battery is used to drive the lamp to emit light. If the ambient light does not operate, the portable lantern is turned on to ensure safe evacuation.

However, in the case of a conventional portable emergency lighting apparatus, there is a problem that it is installed at a position where it can be easily identified at an installation site, but when the surroundings become dark due to the occurrence of a power failure, There is a problem that the charging power stored in the battery is discharged due to the elapse of time even when the portable lantern is not used, so that it is not turned on in an emergency.

In addition, if an emergency situation such as flooding or leakage occurs in the installation place, the power supply is shut off due to the occurrence of a secondary accident such as a short circuit. In this case, as in the case of power failure, the surroundings become dark, There is a problem that identification is limited.

Meanwhile, in the above-mentioned designated place, a fire detection device capable of detecting a fire occurrence is operated, but when a fire is detected in a place where a fire detection sensor for detecting a fire is not disposed, Even if it leads to a fire, there is a problem in that immediate measures are limited as the fire is detected.

In addition, in the conventional fire alarm system, only the management room having the control device for monitoring the operation of each fire detection device can roughly check the location of the fire, and the residents can check the location of the fire Because there is no way to do so, in the situation where the toxic gas from the fire is filled in the room, each occupant could find a more dangerous situation as he or she locates the place to evacuate by the central heating and even evacuates to the place where the fire occurred. Resulting in increased personal injury.
