<p>The present invention relates to a device for extending a lighting time of an emergency light. Since the emergency light is automatically turned on upon power failure, it is possible to further improve a general emergency light installed indoor for the purpose of preventing power failure and various safety accidents and further extend the lighting time of the emergency light for prevention of power failure accidents, thereby strengthening an emergency preparedness system. In the device according to the present invention, an accommodation room of a chemical light is additionally formed at one side of an emergency light body. A general chemical light is accommodated in the accommodation room. When a self-charger of the emergency light is fully used up upon power failure, the chemical light is turned on. Hence, a lighting time by the self-charger is added to a lighting time of the chemical light, thereby obtaining an effect of a relatively long emergency lighting.Therefore, upon unexpected power failure, it is possible to additionally secure considerable time of indoor lighting of various buildings, thereby further improving a preparedness effect on power failure accidents. In addition, it is possible to prevent occurrence of various safety accidents and industrial disaster. The emergency light according to the present invention greatly contributes as an equipment for a national safety and disaster preparedness and is a useful invention.</p> |
