摘要：A method and device are provided for controlling the light emitted by a lightsource. The light is set (303) to an active level in response to a triggering event (302)
indicating presence of a user. A timer is started (304) and run until expiry to measure aperiod of time until the light is to be set to a passive level. If the timer expires (305)without any new triggering event (306) having been observed, the light is set (301) to saidpassive level. An external control signal received (307) while the timer is running andindicating presence of a user elsewhere changes (308) the time remaining until expiry ofthe timer. After having received a plurality of such external control signals, differentsources of external control signals are associated with specific amounts of time by whichthe time remaining until expiry of said timer will be changed. Next time when an externalcontrol signal is received (307) while the timer is running, the time remaining until expiryof said timer is changed (308) by an amount associated with the source from which theexternal control signal was received.
