Abstract

La présente invention concerne une grande signalisation électronique à DEL destinée à afficher des images, la signalisation électronique à DEL comprenant : un processeur destiné à envoyer un signal d'image à la signalisation électronique à DEL tout en réglant la couleur et la luminosité ; un dispositif de commande de système destiné à commander un boîtier qui constitue la signalisation électronique à DEL de façon à compléter un système entier ; une unité d'alimentation électrique destinée à fournir une énergie prédéfinie au boîtier ; et une unité de signal d'image destinée à fournir un signal d'image au boîtier. L'unité d'alimentation électrique comprend : une unité d'alimentation électrique de base destinée à fournir un courant alternatif prédéfini au boîtier ; et une unité d'alimentation électrique de secours destinée à sauvegarder le courant alternatif. L'unité de signal d'image comprend : une unité de signal d'image de base destinée à fournir un signal d'image au boîtier ; et une unité de signal d'image double destinée à fournir un signal d'image double au boîtier. Avantageusement, l'énergie fournie au boîtier est divisée, et la forte énergie est convertie en énergie faible, ce qui garantit une alimentation stable. Si l'énergie fournie par l'unité d'alimentation électrique de base devient anormale ou si un court-circuit se produit en raison d'un courant excessif, une alimentation de secours est fournie, garantissant ainsi une utilisation sûre. Des signaux d'énergie et d'image sont fournis en toute sécurité sans fil dans un module de DEL, ce qui permet d'améliorer sensiblement la productivité, et les défauts résultant des opérations de câblage peuvent être complètement éliminés. Une puce de DEL est revêtue afin de lutter contre des impacts physiques ou l'humidité, ce qui empêche la fracturation ou l'endommagement de la puce de DEL.
