Emergency light

The emergency lighting is lighting that is effective in disruption of power supply to the general electrical lighting or remains.

Generally

Buildings can be large and confusing. In case of power failure, the orientation is often very difficult, if not impossible. A completely from the normal power grid independent, second illumination system having an independent power supply allows the safe and rapid exit of the building and facilitates the use of rescue teams.

The emergency lighting is made between security lighting and standby lighting. When security lighting can be made between " security lighting for escape routes ", " anti -panic " and " Safety lighting for hazardous workplaces ".

Security lighting

The security lighting allows people to safely leave a room or a building in case of danger, for example, to find an emergency exit, or terminate a dangerous workflow. Part of the security lights are illuminated signs bearing the " little walking man on a green background ." These are also security management systems. In addition, the security lighting also allows emergency services, such as the fire brigade, the orientation during the rescue of persons in the building. A special feature is available in rail, tram, and subway tunnels: where the emergency exits are marked with green instead of blue, illuminated exit sign to avoid confusion with railway signals.

Emergency lighting for escape routes

The " security lighting for escape routes " about to leave a place safely helps ( evacuation). It makes it possible to find fire and safety equipment.

Anti-panic lighting

The " anti -panic " to avoid panic in the dark. The anti -panic lighting has to be evenly distributed, no more than the ratio of the maximum to the minimum illuminance 40:1 may be allowed. After five seconds, 50 % of the required illuminance must be present after one minute 100 % (DIN EN 1838).

Standby lighting

The replacement lighting ensures that during a power failure, the work for a certain time can be continued. Spare lights used for example in surveillance systems, command offices of security agencies or industrial facilities or in operating rooms of hospitals.

Power supply

The power is supplied from a standby power source. This may be an emergency generator or battery -supported. The emergency lighting system may be used as ( continuous lighting operation ) or in standby circuit (switching on the lights at power failure) are operated. There is also the possibility of switching on and off of lamps. Here, the lights are then fitted with the electronic modules, which are driven either by means of a local control push-buttons or of a data bus. In case of power failure of the normal power supply, the electronic modules for a forced switch on the emergency lights provide ( powered by the backup power source).

Trade association rules

Information about design of safety management systems and safety lighting in workplaces are included in the BG rule for Safety and Health at Work:

German standards

The " emergency " is highly regulated by standards. Examples of relevant standards in Germany are:

  • DIN EN 1838: Emergency lighting
  • DIN VDE 0108 Power installation and safety power supply in communal facilities DIN VDE 0108-2 for places of assembly
  • DIN VDE 0108-3 for commercial buildings and exhibition centers
  • DIN VDE 0108-4 for high-rise buildings
  • DIN VDE 0108-5 for restaurants and hotels
  • DIN VDE 0108-6 for closed car parks
  • DIN VDE 0108-7 for workplaces
  • DIN VDE 0108-8 for temporary structures as places of public assembly, ...

The standard series DIN VDE 0108 parts 1 to 8 was replaced on 1 October 2005 by DIN VDE 0100-718 in combination with DIN VDE 0100-560 and DIN EN 50172 (VDE 0108-100 ), but was still allowed to March 1, 2007 be applied.
