Accordingly, as the laser beam is scanned only in one direction within a certain angle range in the laser diode 152 of the laser induction module 150, the direction of evacuation of people is induced.

This is because, when smoke such as fire is generated, the projection of light is interfered by smoke, and the direction of evacuation through light projected from the light emitting module 130 can not be smoothly displayed. However, due to the characteristics of the laser beam, The laser beam can be visually distinguished more clearly, so that when there is no smoke, the light emitting module 130 can present the evacuation direction, and when the smoke is generated, the laser beam is guided through the laser induction module 150 in the evacuation direction To evacuate quickly.

The light emitting module 130 and the laser induction module 150 may be used at the same time, and any structure or configuration capable of promptly guiding people in the event of a fire or an emergency can be used. It is possible.
