The invention of fire dust from the smoke, and makes it possible to secure visibility, by the evacuation obtain guidance light is byeongak the guidance display other secure the outlet-side direction, even if the fire is not a guidance display direction from the direction indicating all the time there is no fire as safe evacuation phrase indicating that the outlet only guide to guide light, which body (10), the fixed plate 20, optical sight portion 30, the direction guidance display unit 31, a power supply (40), LED and LED driver (50 ) by the evacuation obtain and to guide light control unit 60, first and second thermal sensor (70) (71), a laser generator 80, and a laser beam passage opening (85), side parts (90 comprising a) and hayeoseo an auxiliary storage 100, the visibility due to smoke more accurately even in difficult situations itgo a remarkable effect that can lead to evacuation safety, and the laser to other evacuation obtain guidance light original evacuation sphere or installed adjacent to the normal investigate the light The laser beam irradiation, etc. evacuation obtain induction is installed adjacent to and at the same time which can be useful in place of refuge, obtain a two-way use to FIG refractive irradiated with another evacuation port side direction than the evacuation port side of the usual advantages of a laser generator body left and right side surface or there is an effect capable of installing both apply regardless of the evacuation passage structure can be installed to the front.
