voici, sans prendre des airs mystérieux, l'explication de la façon dont l'animation est réalisée par le produit mis au point par le fabricant allemand Nightgraphix en 2007:
More info below translated from German
The principle:
A micro CONTROLLER gets a signal per revolution.
From this the time of a revolution is calculated.
This time is divided into columns, in those up to 64 LEDs
per rotor blade to be time-exactly headed for can.
PC the Tool:
The pictures which can be indicated can be provided with PC a software.
Thus image files know imported, text written,
individual pixels to be set.
If one provided a picture, one can store it,
transfer and to the rotor blades.
The versions:
There are different versions, dependent on the sheet length.
The longer the sheet, the more LED are processed.
The LED modules are cascadeable to 8 LEDs each.
Only the NG-16 system makes thereby the exception,
since it is meant as graphic text version for each sheet length.
et voila comment donner une info précise sans besoin de citation latines
