Abstract

L'invention concerne un procédé de fabrication d'un panneau d'accumulation de lumière qui peut être visiblement reconnu la nuit et dans des endroits sombres, et qui est mince tout en présentant une grande résistance, sans générer de fissures et similaire sur une surface d'impression pendant la fabrication. Un verre fritté et une partie proche d'une section d'extrémité d'un panneau de métal (W) sur lequel un matériau d'accumulation de lumière est imprimé sont supportées en une pluralité de points supports (2) à maintenir horizontalement. De plus, une butée (3) pour limiter le gauchissement du panneau de métal (W) est disposée sur la surface arrière du panneau d'accumulation de lumière près du centre du panneau d'accumulation de lumière, puis on effectue la cuisson pour faire fondre le verre fritté. Ensuite, on effectue le refroidissement pour solidifier le verre fritté et contracter le panneau de métal (W), et on obtient le panneau d'accumulation de lumière dont le côté de surface d'impression est horizontal ou légèrement gauchi.
