A lighting system for an emergency exit from an occupied space comprising an array of lighting elements 15, 16 located around the emergency exit to illuminate the exit and facilitate egress for an occupant of the space. Sensors 12, 13, 14 detect one or more trigger conditions and a control unit actuates the lighting elements in response to a first trigger condition from any of the sensors. The sensors comprise 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. |
