Abstract

An integrated lighting control and threat detection system is provided. Once one of the threat detectors determines that a hazardous condition exists, it transmits a threat message to the lighting control system. The lighting control system then operates to turn on illumination within the dwelling to aid in an occupant'"'"'s safe exiting from the dwelling. The lighting control system operates to illuminate all lights within a dwelling upon detection of a hazardous condition. Alternatively, the lighting control system operates to illuminate preselected paths of lighting as programmed by a user. Still further, coordinated illuminated control may be provided based upon the location of the detected hazardous condition and the fixed and portable lights within a dwelling. Both fixed and adaptive illumination control are provided as is a fail safe illumination of all lights within a dwelling should each of the pre-selected exit paths contain a hazardous condition.

Claims

1. A system for providing controlled illumination within a structure during a detected hazardous condition, comprising:

at least one threat detector;

a lighting control system in communication with the at least one threat detector, the lighting control system being configured to control illumination of a plurality of lights that normally provide illumination within the structure (hereinafter “

controlled lights”

); and

wherein the lighting control system is configured to illuminate less than all of the plurality of controlled lights to provide illumination within the structure upon receipt of a threat detected signal from the threat detector.

2. The system of claim 1, wherein the lighting control system is programmable to turn on predetermined ones of the plurality of controlled lights upon receipt of a threat detected signal from the threat detector.

3. The system of claim 2, wherein the lighting control system is configured to turn on controlled lights located in sleeping quarters and controlled lights leading to an exit and to leave controlled lights in other locations within the structure in their current state.

4. The system of claim 2, further comprising a plurality of threat detectors positioned at different locations within the structure, and wherein the lighting control system is configured to turn on a different combination of controlled lights depending on which one of the threat detectors transmits the threat detected signal first.

5. The system of claim 4, wherein the lighting control system is configured to modify the combination of controlled lights that it turns on when other threat detectors transmit the threat detected signal.

7. The system of claim 1, further comprising a plurality of threat detectors positioned at different locations within the structure, and wherein the lighting control system is configured to turn on predetermined ones of the plurality of controlled lights upon receipt of a threat detected signal from one of the threat detectors based on the location thereof.

8. The system of claim 7, wherein the lighting control system is configured to turn on predetermined ones of the plurality of controlled lights upon receipt of a threat detected signal from one of the threat detectors based on a location of exits from the structure.

6. A system for providing controlled illumination within a structure during a detected hazardous condition, comprising:

at least one threat detector;

a lighting control system in communication with the at least one threat detector, the lighting control system being configured to control illumination of a plurality of lights that normally provide illumination within the structure; and

wherein the lighting control system is configured to illuminate at least one of the plurality of lights to provide illumination within the structure upon receipt of a threat detected signal from the threat detector;

wherein the lighting control system is programmable to turn on predetermined ones of the plurality of lights upon receipt of a threat detected signal from the threat detector;

further comprising a plurality of threat detectors positioned at different locations within the structure;

wherein the lighting control system is configured to turn on a different combination of lights depending on which one of the threat detectors transmits the threat detected signal first; and

wherein the lighting control system is configured to turn on all of the plurality of lights when it receives the threat detected signal from a number of threat detectors indicating that exits may be blocked by the detected hazardous condition.

9. A lighting control system to control the illumination of lights that normally provide illumination in a structure (hereinafter “

controlled lights”

), the structure having at least one hazardous condition detector located therein and at least one exit leading therefrom, comprising a lighting system controller configured to turn on less than all of the controlled lights in the structure to provide illumination within the structure upon receipt of a threat detected signal from at least one hazardous condition detector.

10. The system of claim 9, wherein the lighting system controller is programmable to turn on predetermined ones of the plurality of controlled lights upon receipt of a threat detected signal from the hazardous condition detector.

11. The system of claim 10, wherein the lighting system controller is configured to turn on controlled lights located in sleeping quarters and controlled lights leading to an exit and to leave controlled lights in other locations within the structure in their current state.

12. The system of claim 10, wherein the lighting system controller is configured to turn on a different combination of controlled lights depending on which one of the hazardous condition detectors from which the lighting system controller receives the threat detected signal first.

13. The system of claim 12, wherein the lighting system controller is configured to modify the combination of lights that it turns on when the threat detected signal is received from other hazardous condition detectors.

14. The system of claim 9, wherein the lighting control system is configured to turn on predetermined ones of the controlled lights upon receipt of a threat detected signal from one of the hazardous condition detectors based on a location thereof in the structure.

15. The system of claim 14, wherein the lighting system controller is configured to turn on predetermined ones of the controlled lights upon receipt of a threat detected signal from one of the hazardous condition detectors based on a location of exits from the structure.

16. The system of claim 9, wherein the lighting system controller is configured to control illumination of fixed lights in the structure and is user programmable to control illumination of portable lights by controlling energization of electrical outlets into which the portable lights are plugged.

17. A method of providing controlled illumination of lights that normally provide illumination within a structure (hereinafter “

controlled lights”

) during a detected hazardous condition, the structure having at least one hazardous condition detector positioned therein and at least one exit leading therefrom, comprising the steps of;

receiving a threat detected signal transmitted from one of the at least one hazardous condition detector;

turning on less than all of the controlled lights to provide illumination within the structure in response to receiving the threat detected signal.

18. The method of claim 17, wherein the step of turning on less than all of the controlled lights within the structure comprises the step of turning on less than all of the controlled lights including at least one fixed and portable lights.

19. The method of claim 17, wherein the step of turning on less than all of the controlled lights within the structure comprises the step of turning on predetermined ones of the controlled lights leading to the at least one exit.

20. The method of claim 19, wherein the step of turning on predetermined ones of the controlled lights leading to the at least one exit comprises the step of turning on predetermined ones of the controlled lights leading to the at least one exit while leaving controlled lights in a location near the detected hazardous condition in a current state.

21. A method of providing controlled illumination of lights that normally provide illumination within a structure during a detected hazardous condition, the structure having at least one hazardous condition detector positioned therein and at least one exit leading therefrom, comprising the steps of:
