The scene is a fire in a highrise and the ensuing chaos can make it difficult for people to locate exits. In such scenarios, the Light Emitting Door could mean the difference between life or death. A bright LED located at the foot of the door directs people to a hinged shutter, kinda like a doggy door. I think its a neat idea and worth installing.
Light Emitting Door is a 2010 Red Dot Concept Award winning design.
