Abstract

See full text

A laser light fire evacuation system, and a method for its use, is provided including a source of laser light in the visible spectrum which is directed into multiple vertical columns of light extending from the ceiling to the floor of a hallway or corridor, in which the multiple columns are sequenced from left-to-right or from right-to-left during a fire to appropriately direct persons to the nearest safe exit. Each column of laser light is nearly invisible when the smoke density in the air is at a low level, however, as the smoke density increases, the laser light beam will increase in perceived intensity and consistency. In one embodiment, the laser light source is directed toward a rotating mirror which redirects the light into a rotating beacon as the mirror rotates. Several fiber optic cables are located around the periphery of the rotating mirror and intercept the light beam, thereby having laser light directed down each of the fiber optic cables, in sequence. The fiber optic cables are installed above the ceiling of a hallway or corridor and terminate in several locations along the ceiling of that corridor or hallway. As laser light is sequentially directed down each of these fiber optic cables, it will produce a sequencing pattern of laser light columns that each extend from the ceiling to the floor along that corridor or hallway. The beam rotator can be turned in either the clockwise or counter-clockwise direction to reverse the sequence of the light columns. Another embodiment uses adjustable mirrors to redirect the direction of the laser light beam. A third embodiment uses electrical cables and laser diodes to individually created columns of sequenced laser light.
