Abstract

L'invention concerne une plaque conduit de lumière (1) fabriquée par impression offset et une méthode de fabrication de celle-ci. Un côté de la plaque conduit de lumière (1) est doté d'une trame de points conduits de lumière (2, 3) de différentes formes, différentes tailles ou différentes densités par impression offset. Les points conduits de lumière de la trame (2, 3) se combinent pour créer des motifs et des textes différents. On peut utiliser de nouveau l'impression offset sur le dessus de parties de la trame de points conduits de lumière (2, 3) de la plaque conduit de lumière (1) pour former une grande trame épaisse de points conduits de lumière (2, 3) par superposition. La plaque conduit de lumière (1) de la présente invention peut résoudre les problèmes d'éblouissement sans utiliser de matériaux diffusifs ou réflecteurs, et permet l'émission directe de lumière, ce qui réduit la consommation d'énergie, améliore l'efficacité lumineuse, réduit les coûts et permet donc une utilisation répandue.
