Abstract: Disclosed is a light-material coupling and emitting apparatus for coupling and emitting light and a material. The present disclosure is to utilize light coupled with a gaseous material or a certain state of material. According to the present disclosure, light is coupled with a gas, a liquid, or any state (plasma state) of material, and the coupled light and the material are emitted toward a target object or a predetermined region. When reaching the target object or the predetermined region, the material reacts with another material existing around the target object or the predetermined region. According to one embodiment, when light coupled with a first material is emitted from the light-material coupling and emitting apparatus, the first material coupled with the light falls away from the light and then chemically reacts with a second material. The apparatus uses a specific effect caused by this chemical reaction.

Abstract: Disclosed is an emergency guidance apparatus which displays direction, situation informing letter and sign in a display unit, outputs a sound in a speaker, and turns on flickering light towards the right direction to evacuate so that the apparatus can guide evacuation and minimize the human casualties depending on the disaster type and situation. The emergency guidance apparatus with lighting according to an embodiment of the disclosure, which transmits to a central control unit the disaster signals detected by the disaster detection sensors that are installed in multiple places within building, and receives the processing signals transmitted by the central control part so as to guide the evacuation direction.
