<p>PROBLEM TO BE SOLVED: To automatically light a bulb through a bulb lighting means so as to secure the safety of a resident to evacuate quickly and surely when the an earthquake is detected by providing a tremor detection means detecting the tremor, and lighting the bulb through the bulb lighting means when the tremor detection means detects the tremor higher than a predetermined value. SOLUTION: A device is composed of an emergency light main body 1 and a charging base 20. A control circuit 14 in the emergency light main body 1 is composed of a microcomputer and its peripheral circuits, and controls the operation of bulb 3 on and off, or the like. A photosensor 10, a vibration sensor 15 detecting a tremor, and a battery state detection circuit 18 detecting the voltage of a charged battery 12 are inputted in the control circuit 14. A red light emitting LED 7, a charging lamp, is connected to the output of the control circuit 14. A forced OFF switch 6 is connected between a light switch 19 and the bulb 3.</p> |
