  • Said aerostats are presently used for various purposes, among which we can mention touristic, amateur or advertising and promotional purposes.
  • the external surface of the balloon bears messages, for example promotional or information messages in general, images, drawings, etc.
  • the balloons can also be provided, on their external surface, with lighting devices intended to increase the visibility of said advertising or promotional messages in general when visibility is scarce, for example when there is insufficient light or no light at all.
  • the subject of the present invention is a new lighting system for aerostats like hot- air balloons and airships.
  • the main object of the present invention is to provide lighting for the display of advertising, promotional or information messages in general, wherein each lighting body, preferably with LEDs, is powered individually and independently of the others.
  • Another important object of the present invention is to make the aerostat lighter, reducing to a minimum the components needed to power and control the operation of the aerostat and the lighting bodies.
  • the new lighting system comprises among its main parts a plurality of lighting bodies, preferably with LEDs, wherein each lighting body is powered independently of the others.
