Abstract

A system and method that helps evacuees exit a residential structure in the event of an emergency such as a fire, earthquake, security breach or the like, by providing emergency illumination around the periphery of an exit door and/or an alternative safe exit portal together with floor/ground level illumination along the path to the portal, and by providing an audible tone or voice recording to guide occupants to the exit portal. Various forms of linear illuminators parallel to and near the floor of an interior room or hallway provide the floor-level identification and illumination of the exit route to be used in the event of emergency, with some linear illuminators having directional aspects along hallways to lead evacuees toward an exit, and other illuminators outlining the perimeter of portals that are safe to exit through, the illuminators normally being hardly noticeable but having controllers and energizers to light up the planned exit route when emergency conditions are detected.

Claims

1. A system and method for enabling visual orientation and providing illumination to evacuees in the event of an emergency requiring evacuation of a residential, commercial, industrial, institutional, vehicular or marine structure or enclosure having portals such as doorways, passageways and/or egress windows, wherein there is a planned path of safe emergency egress from an interior space such as a room, quarters or hallway of said residential, commercial, industrial, institutional or marine structure or enclosure, and wherein said path passes through a portal such as an interior or exterior doorway or window of said structure or enclosure, said system comprising:

a first linear illuminator section positioned along a wall of said interior space in an orientation that is generally parallel to a floor of said space and that is generally near and along the base of a wall of said space, such as along the top or bottom edge of a baseboard of the wall;

a second linear illuminator section that is positioned in a generally vertical orientation along said wall in a location adjacent said portal in said planned emergency egress path;

at least one energizer for energizing said first and second illuminator sections, said energizer(s) being associated with said sections in a manner that causes said sections to illuminate when said energizer(s) is actuated;

said energizer(s) being actuated in response to a signal such as an electrical, electromagnetic or audible or visual signal that is present when emergency conditions are detected by a system-integrated sensor or detector or a single-station detector such as a fire detector, smoke detector, carbon dioxide detector, radon gas detector or a light emission;

a length of said first linear illuminator section being adapted and positioned to provide illumination along a line leading generally toward said second linear illuminator section, to lead evacuees toward said second section when said first section is energized to provide illumination.

2. The system and method of claim 1, further comprising a controller associated with said at least one energizer for regulating illumination of said first and second linear illuminator sections, and wherein said at least one energizer comprises a low-voltage energizer that is engaged when an alternating current power source is disengaged from said controller.

3. The system and method of claim 1, further comprising a controller associated with said at least one energizer for regulating illumination of said first and second linear illuminator sections, and wherein said at least one energizer comprises a low-voltage energizer that is engaged when an alternating current power source is disengaged from said controller through a switching mechanism.

The system and method of claim 1, further comprising a controller associated with said at least one energizer for regulating illumination of said first and second linear illuminator sections, and wherein said controller is adapted to actuate said at least one energizer in response to said signal that is present when emergency conditions are detected by said detector.

5. The system and method of claim 1, further comprising a controller associated with said at least one energizer for regulating illumination of said first and second linear illuminator sections, and wherein said controller is adapted to actuate said at least one energizer in response to a radio frequency (RF) switching mechanism initiated in response to detection of emergency conditions by said detector.

6. The system and method of claim 1, further comprising a housing mounted on the top edge of a trim member on a wall surface in close proximity to an exit portal using materials such as glue, caulk, or mounting nails or screws.

7. The system and method of claim 6, further comprising:

a controller associated with said at least one energizer for regulating illumination of said first and second linear illuminator sections;

wherein

said housing comprises a low-profile injection-molded housing; and

said at least one energizer and said controller are contained within said low-profile injection-molded housing.

8. The system and method of claim 1, further comprising a controller associated with said at least one energizer for regulating illumination of said first and second linear illuminator sections, and wherein said at least one energizer and said controller are contained within an enclosure such as an insulated junction-box.

9. The system and method of claim 8 wherein said enclosure such as an insulated junction-box is recessed into a wall such that said enclosure is flush with the surface of the wall.

10. The system and method of claim 1, further comprising a controller associated with said at least one energizer for regulating illumination of said first and second linear illuminator sections, and wherein said controller is calibrated so that said at least one energizer energizes said first and second linear illuminator sections to flash in a pattern.

11. The system and method of claim 1 wherein said first linear illuminator section comprises an electroluminescent light source consisting of a single strand of electroluminescent wire.

12. The system and method of claim 11 wherein said electroluminescent wire comprises a clear, flexible, sleeve-like outer casing, and wherein said electroluminescent wire provides a bright aqua blue illumination when energized, said bright aqua blue illumination being highly visible to evacuees in said interior space.

13. The system of and method claim 1 wherein said first linear illuminator section comprises double or triple stranded or twisted/braided linear fauns of luminaries, such as, but not limited to, electroluminescent wires, illumination strips, rope lights, plastic optical fibers, or laser beam courses.
