Abstract
An emergency manager for a lighting device (1), which lighting device is configured to transmit information by coding its output light. The emergency manager has a light coding unit (5), configured to code light emitted by a light emitter (3), thereby enabling the light emitter to emit a coded light signal including an individual identifier identifying the lighting device; an emergency indicator (7); and a control unit (9). The control unit is configured to control the light coding unit to adjust the coded light signal to increase a robustness of a transmission of the coded light signal upon receiving an emergency indication from the emergency indicator.
