The operation of steps S406 to S409 is performed when, for example, a fire / pizza (user of the portable flash 20) inputs an operation end signal through a method of placing the lighting control button 290 in an off state, Lt; / RTI >

By the portable flash 20 operating in steps S401 to S409 as described above, the fire escaping person can accurately grasp the distance relation with the emergency exit even in a situation where the field of view is not secured due to the heavy fire smoke, thereby facilitating the emergency exit . For example, when the vibration of the portable flash 20 becomes stronger, the buzzer becomes faster, and the LED flashes faster, the fire preserver becomes aware that the distance from the fire exit guide body 10 is getting closer. In addition, when the vibration reaches a peak, the buzzer sound is heard as a continuous sound, and the LED flashes continuously, the fire escapee can recognize that the fire escape guide body 10 is an emergency exit where the fire exit guide body 10 is located.

For reference, although not shown, the portable flash 20 may further include a built-in fire detection sensor unit. A smoke detection sensor for detecting smoke or a temperature detection sensor for detecting temperature may be applied to the fire detection sensor unit. In this case, when the fire detection sensor unit detects a fire situation, the microcomputer unit 300 turns on the LED unit 260 or generates a buzzer sound in a state where the portable flash unit 20 is mounted on the cradle 40 So that the evacuator can easily confirm the position of the portable flash 20, so that the portable flash 20 can be positively utilized to evacuate.
