Lighting system
First Claim
1. A lighting system for an emergency exit from an occupied space:
- an array of lighting elements locatable around the emergency exit to illuminate the exit and facilitate egress for an occupant of the space;
sensors to detect one or more trigger conditions; and
a control unit to actuate the lighting elements in response to a first trigger condition from any of the sensors, the sensors comprising;
an impulse detector operable to send a signal to the control unit indicating that the impulse detector has experienced an impulse; and
a roll and pitch detector operable to send a signal to the control unit indicating that the roll and pitch detector has experienced roll and/or pitch, wherein upon detection of the first trigger condition the control unit actuates one or more of the lighting elements to illuminate the exit, wherein the roll and pitch detector is operable to send a signal to the control unit only when a sensed roll and/or pitch is greater than a selected threshold roll and/or pitch, and wherein the thresholds for roll and pitch are independently selectable.

Abstract
A lighting system for an emergency exit from an occupied space: an array of lighting elements located around the emergency exit to illuminate the exit and facilitate egress for an occupant of the space; a control unit; and sensors to detect one or more trigger conditions and actuate the lighting elements in response to a first trigger condition from any of the sensors, the sensors comprising: an impulse detector operable to send a signal to the control unit indicating that the impulse detector has experienced an impulse; and a roll and/or pitch detector operable to send a signal to the control unit indicating that the roll and/or pitch detector has experienced roll and/or pitch, wherein upon detection of the first trigger condition the control unit actuates one or more of the lighting elements to illuminate the exit.

16. A lighting system for an emergency exit from an occupied space:
-
an array of lighting elements located around the emergency exit to illuminate the exit and facilitate egress for an occupant of the space; a control unit; and sensors to detect one or more trigger conditions and actuate the lighting elements in response to a first trigger condition from any of the sensors, the sensors comprising;
an extreme movement detector operable to send a signal to the control unit indicating that the extreme movement detector has experienced an extreme movement; and
an extreme orientation detector operable to send a signal to the control unit indicating that the extreme orientation detector has experienced an extreme orientation of roll and pitch greater than a respective independently selectable threshold, wherein upon detection of the first trigger condition the control unit actuates one or more of the lighting elements to illuminate the exit. - View Dependent Claims (19, 22, 26, 27)

17. A method of operating a lighting system in a vehicle for an emergency exit from the vehicle comprising:
-
sensing an extreme movement outside normal vehicle operation and sending a trigger condition to a control unit if an extreme movement is experienced; sensing an extreme orientation of roll and pitch greater than a respective independently selectable threshold, outside normal vehicle operation and sending a trigger condition to the control unit if an extreme orientation is experienced; the control unit detecting a first trigger condition from any sensor; and illuminating an array of lighting elements located around the emergency exit to illuminate the exit and facilitate egress for an occupant of the vehicle from the vehicle. - View Dependent Claims (20, 23, 28, 29)
