As such, the emergency lamp 21 is preferably formed by combining three high-speed white lamps (LEDs) in a triangular shape, and when used in an emergency such as a fire or a power failure, loss of direction due to smoke causes human injury. This can be minimized (especially when a fire occurs during sleep, such as at night or at dawn).

In addition, among the sensors of the sensor unit 40, the sensor 45 that detects a flame (flame) analyzes the characteristics of the infrared and ultraviolet wavelength regions of the flame when the flame (flame) is generated inside the installed place. When the analyzed characteristic is recognized as a fire, the recognized signal is input to the microcomputer 60 and then drives the operation driver 100 by the control signal of the microcomputer 60 to store the extinguishing liquid stored in the fire extinguisher 10. It is sprayed on a flame (fire) to extinguish the fire early.

Referring to the operation driving unit 100, first, when the flame of the fire is recognized through the flame sensor 45, the injection hole 12 of the fire extinguisher 10 should be rotated in the direction in which the flame is generated.

To this end, when the signal of the microcomputer 60 is outputted, the injection hole direction switching motor 110 is driven to rotate in a desired direction according to the output signal, and the linear gear is driven by the injection hole direction switching motor 110. Since the linear gear 111 is engaged with the switching gear 12a formed at the rear end of the injection hole 12 of the fire extinguisher 10, the switching gear 12a is driven by the linear gear 111. ) Is also driven to rotate the injection hole 12 of the fire extinguisher 10 at a predetermined angle in a desired direction.
