Abstract

An improved system and method for providing emergency lighting and directional exit indication in the event of power outage and/or smoke/fire events. The system provides a lighted pathway consisting of discrete points of light, some of which strobe or trace toward the exits and others of which burn steadily for general area emergency lighting. The method consists of detecting the emergency condition and illuminating the appropriate emergency lighting.

Claims

1. An emergency lighting system for illuminating routes within a building, said emergency lighting system comprising a plurality of discrete point sources of light placed in at least one row along the interior walls of the building wherein said plurality of discrete point sources of light comprise dynamic tracer lights and wherein said discrete point sources of light are configured to be triggered without the use of a computer processor by at least one detector for detecting the occurrence of an emergency situation and wherein said discrete point sources of light are configured to be powered by at least one power supply source.

2. The emergency lighting system of claim 1, wherein said plurality of discrete point sources of light further comprise static lights.

3. The emergency lighting system of claim 2, wherein said static lights are white or clear.

4. The emergency lighting system of claim 1, wherein said dynamic tracer lights are colored.

5. The emergency lighting system of claim 1, wherein said plurality of discrete point sources of light are installed on rigid or semi-rigid strips such as baseboards, chair rails or other molding.

6. The emergency lighting system of claim 1, wherein said plurality of discrete point sources of light are arranged onto flexible strips.

7. The emergency lighting system of claim 1, further comprising:

a. heat detection sensors installed at or near exit doors; and

b. control circuitry to reverse the direction of the tracer lights in the event that said heat detection sensor(s) detect temperature at or near an exit door that exceeds a safe temperature for emergency egress.

8. The emergency lighting system of claim 1, wherein said at least one row of the plurality of discrete point sources of light consists of two or more rows of discrete point sources of light with at least one row dedicated to emergency lighting and the other row(s) connectable to a building'"'"'s sound system for pulsing with music for entertainment purposes.

9. An emergency lighting system for illuminating routes within a building, said emergency lighting system comprising a plurality of discrete point sources of light placed in at least one row along the interior walls of the building wherein said plurality of discrete point sources of light comprise white or clear static lights interspersed with colored dynamic tracer lights and wherein said discrete point sources of light are configured to be triggered without the use of a computer processor by at least one detector for detecting the occurrence of an emergency situation and wherein said discrete point sources of light are configured to be powered by at least one power supply source.

10. The emergency lighting system of claim 9 further comprising:

a. heat detection sensors installed at or near exit doors; and

b. control circuitry to reverse the direction of the tracer lights in the event that said heat detection sensor(s) detect temperature at or near an exit door that exceeds a safe temperature for emergency egress.

11. A method for providing illuminated exit routes, the method comprising the steps of:

a. detecting an emergency event(s);

b. triggering a plurality of discrete point sources of light placed in at least one row along the interior walls of the building without using a computer processor wherein said plurality of discrete point sources of light are dynamic tracer lights.

12. The method of claim 11 further comprising triggering static lights without using a computer processor.

13. The method of claim 12 wherein said emergency event is a power outage.

14. The method of claim 11 wherein said emergency event is a smoke/fire event.

15. The method of claim 11 further comprising the step of detecting whether the temperature at the exit(s) exceeds a safe temperature for egress.

16. The method of claim 11 further comprising the step of reversing the direction of the strobing of the dynamic tracer lights.
