Abstract
A method for controlling guiding, signal or alert lights, particularly signal lights for an emergency escape route in a fire situation, in which method there are controlled sequentially arranged light sources, such as LED light sources. In the method, in the first step the sequentially arranged light sources (), which are most advantageously arranged as a light source string () or at least as part thereof, are activated, on the basis of a signal received from a fire detector (), to be switched to a first mode, in which first mode the sequentially arranged light sources are used for indicating the direction of an escape route, and/or to a second mode, where the light sources () are switched to emit continuous light. The invention also relates to a system and a device.
