Definitions

  • the present invention relates to an emergency lighting device intended to be installed in buildings to indicate emergency exits and to illuminate evacuation routes leading thereto.
  • One field of application envisaged is in particular that of guiding people in a building during an emergency evacuation, for example in the event of a fire or a power cut.
  • beaconing models comprise a substantially rectangular parallelepipedic box on the front face of which a safety or signaling pictogram is displayed. Also, the device comprises a lighting member housed inside the case so as to be able to illuminate the pictogram to highlight it.
  • the case has a lower edge also equipped with lighting means.
  • the box is installed, in buildings, in height and in particular above the doors so as to be able to mark out and illuminate, thanks to the lighting means mounted on the lower edge of the box, the escape routes.
  • Autonomous emergency lighting units also include a battery to ensure their operation and more specifically the lighting, when the building's power supply is cut.
  • the lighting power required varies according to the buildings and also according to the position in the buildings.
  • the escape routes can be illuminated with a light intensity greater than 0.5 lux on the ground.
  • the same box provides predetermined light fluxes, while the light intensity on the ground varies in particular according to its distance from the ground.
  • a problem which arises and which the present invention aims to solve is to provide lighting devices making it possible to reduce the number of boxes necessary and consequently to reduce installation costs.
