Method, system and device for signaling, guiding and alerting
First Claim
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, andtransmitting 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, andproviding in the structure an indication of a specific one of the multiple escape routes that leads to the corresponding exit.

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 (40), which are most advantageously arranged as a light source string (4) or at least as part thereof, are activated, on the basis of a signal received from a fire detector (3), 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 (40) are switched to emit continuous light. The invention also relates to a system and a device.

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. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10)

11. A signaling, guiding or alert light system in a structure having multiple escape routes, each of the escape routes leading to a corresponding exit of the structure, the system comprising:
-
a control device, light sources sequentially arranged in at least a portion of a light source string in each of the escape routes, and one or more fire detectors adapted to send a fire detection signal to the control device, the control device being adapted to transmit a first signal to the light source string to enable the light sources sequentially arranged on at least a portion of the light source string to operate in a first mode, and to transmit a second signal from the control device to the light source string to enable 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, wherein the control device is adapted to transmit the first signal to the light source string of each of the multiple escape routes, in order to switch the light sources in the light source string of each of the multiple escape routes to the first mode, and to provide in the structure an indication of a specific one of the multiple escape routes that leads to the corresponding exit. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
