1. A virtual safety corridor system for use in emergency situations, the virtual safety corridor system comprising:
an activation system comprising one or more detectors;
a laser control unit in communication with the activation system;
the laser control unit comprising one or more first laser units, the one or more first laser units configured to project a pair of virtual vertical walls, the virtual vertical walls forming a virtual safety corridor projected toward an emergency exit to guide or direct a person to the emergency exit;
an exit arrangement system, the exit arrangement system positioned above the emergency exit and comprising a bar and a plurality of second laser units, the bar being an elongated housing and the plurality of second laser units mounted to the bar;
a first of the plurality of second laser units substantially aligned with a first of the pair of virtual vertical walls and positioned above a first deflector, and a second of the plurality of second laser units aligned with a second of the pair of virtual vertical walls and positioned above a second deflector;
the first deflector configured to convert a substantially vertical laser beam projected from the first of the plurality of the second laser units toward the first deflector into a first substantially horizontal laser beam, and the second deflector configured to convert a substantially vertical laser beam projected from the second of the plurality of the second laser units toward the second deflector into a second substantially horizontal laser beam, the first and second substantially horizontal laser beams each directed away from the emergency exit to create a virtual floor extending from the emergency exit, the virtual floor being substantially perpendicular to the emergency exit and located above and substantially parallel to a floor;
a third and fourth of the plurality of second laser units each configured to project vertically fanned laser beams toward a frame of the emergency exit such that the vertically fanned laser beams illuminate the frame,
wherein, because the pair of substantially horizontal laser beams is projected away from the emergency exit, the pair of substantially horizontal laser beams are projected onto the front of the person when the person is facing the emergency exit, thereby providing an indication that the person is traveling toward the emergency exit.
