Rotating light emitting diode graphic or image display having rotating disc with radial LED networks having diodes and central card providing command signals and electrical power

Systeme de visualisation d'images utilisant des elements electroluminescents

Abstract

The image display has a rotating disc (102) with radial LED networks (103-106) each network with a number of diodes (107-110). A central card (120) provides LED command signals and electrical power. A coder provides transparent and opaque sections. An origin detector (123) detects an origin bar.
<P>Un système de visualisation d'images comprend une multiplicité de réseaux de diodes électroluminescentes (103-106) disposés radialement sur un disque tournant (102); un codeur (122) associé à une multiplicité de capteurs de position (124-127); une fenêtre transparente (115) montée le long d'un bord extérieur d'un disque fixe (101), un moteur d'entraînement (131) pour faire tourner le disque tournant par l'intermédiaire d'une courroie (136); et un port de communication (138) pour transmettre à une carte principale de circuits électroniques (120) des signaux d'information et de commande provenant de l'extérieur, pour visualiser des images par l'éclairement sélectif des diodes électroluminescentes portées par le disque tournant (102).</P>
