Abstract:
1. A method for controlling guiding, signal or alert lights in a structure having multiple escape routes, each of the escape routes leading to a corresponding exit of the structure, each of the escape routes having a light source string having multiple light sources showing a way to the corresponding exit, the method comprising: sending a fire detection signal from one or more fire detectors to a control device, transmitting a first signal from the control device to the light source string, thereby enabling the light sources sequentially arranged on at least a portion of the light source string to operate in a first mode, and transmitting a second signal from the control device to the light source string, thereby enabling the light sources sequentially arranged on the at least a portion of the light source string to operate in a second mode, the first mode being a dynamic mode indicating a guiding direction of movement by switching on a next one of the light sources sequentially arranged on the at least a portion of the light source string, and by switching off a preceding one of the light sources, and thereafter by repeating the on and off switching of the next and the preceding pairs of light sources along a length of the at least a portion of the light source string, the second mode being a static mode indicating that the guiding direction of movement is away from the at least a portion of the light source string by switching each of the light sources thereon to a state of emitting continuous light, the method further comprising: transmitting the first signal from the control device to the light source string of each of the multiple escape routes, switching the light sources in the light source string of each of the multiple escape routes to the first mode, and providing in the structure an indication of a specific one of the multiple escape routes that leads to the corresponding exit.
