Description

Emergency exit guide lamp for displaying emergency exit distance and lamp battery charge state}

The present invention relates to an emergency exit induction lamp, and more specifically, a distance display unit in which the distance to the emergency exit (emergency exit) is emitted numerically, and near-infrared light so that it can be more advantageously identified even in adverse conditions such as haze and fog. Inductive display part consisting of multiple light emitting elements in the wavelength band close to the outside light, and alarm buzzer that automatically alerts or checks the power failure of the commercial power supply, abnormal charging of the rechargeable battery, and life of the rechargeable battery, and judges if it is abnormal. And the charging fault display unit to evacuate more safely and urgently in an emergency.

In general, the corridors, passages and exits of public places, buildings, and transport vehicles such as passenger ships, airplanes, and trains, which are used by many people, are particularly emergency exits that prompt evacuation to exits (emergency exits) in the event of an emergency such as a fire. Induction lamps are installed.

The emergency exit induction lamp is additionally provided with an illumination lamp for easy identification even at night or in the dark, and a charging circuit and a rechargeable battery are installed in preparation for a power failure of a main power source. And, usually, the induction lamp is turned on and illuminated by the commercial power, and when the commercial power is outage, the charging power (emergency spare power of the battery) is automatically switched to use the induction lamp to maintain the operating state.

On the other hand, the conventional emergency exit induction lamp uses a filament bulb with a relatively high power consumption, and the filament bulb must be turned on at all times even in a normal state, resulting in a large waste of power and a reduction in the lifespan of the filament bulb and the fluorescent lamp, and the cost of frequent replacement. .

In addition, the conventional emergency exit induction lamp is required to turn on the filament bulb or fluorescent lamp with low power consumption while the power consumption is high as a rechargeable battery at the time of power failure, it is difficult to display the emergency exit induction lamp, and the brightness of the filament bulb or fluorescent lamp is weak during power failure or fire If the haze or fog occurs because the wavelength is long, there is a problem in that the brightness is sharply dropped to fully exhibit the emergency induction function.

And, in case of fire in a building or inside a train, people who do not know the internal structure takes a lot of time to escape. Most people don't know how far they need to go, and those who know what's going on inside are embarrassed or nervous, forgetting information like the direction and location of their exits, as well as their own alarms. In many cases, escapes were not noticed, preventing them from seeing the exit sign.

Moreover, in the past, it is inconvenient to test whether the system is operated at a long time all the time, and there is no function of self-diagnosing and alarming the failure of the rechargeable battery and the abnormality of the charging circuit, so that the system is blocked by the failure of the rechargeable battery in case of sudden power failure or fire. Or there is a problem such as an increase in the damage to people and / or property damage due to malfunction.

Therefore, the present invention is designed to solve the above-mentioned conventional problems, mainly when an outage occurs due to an emergency such as a fire to generate an alarm sound to emergency emergency evacuation to the emergency exit (함으로써 口) by emergency It is aimed at making it possible.

In addition, the present invention lights up the induction display unit for indicating the direction of the emergency exit and the light emitting element indicating the reach to the emergency exit (emergency exit) to deliver the evacuation direction and evacuation distance to the escape, so that you can evacuate quickly without panic. For the purpose.

In addition, the present invention is embarrassed by displaying the direction display section and the distance display section with a light emitting device having a wavelength band close to near infrared light so that it can be more advantageously identified even in poor vision or other adverse conditions caused by fog or mist. It aims to be able to evacuate urgently without doing so.

In addition, when an emergency situation occurs, the direction display unit and the distance display unit alternately blinks to make it easier to identify and recognize.

In addition, the present invention automatically checks the normal charging status and the life of the rechargeable battery, which is a spare power supply, if there is an abnormality, it will be displayed by flashing the charging abnormality display part with a light emitting element at the same time as an alarm to maintain a good operating state of the emergency exit induction lamp. For the purpose.
