Abstract

L'invention concerne une bande lumineuse de DEL de forme spéciale et un procédé de fabrication. Plus particulièrement, des cartes de circuits imprimés de bandes lumineuses sont conçues pour être disposées en parallèle. De haut en bas, les deux cartes de chaque paire de cartes de circuits imprimés de bandes lumineuses verticalement adjacentes sont connectées l'une à l'autre de manière décalée, c'est-à-dire que les cartes de circuits imprimés de bandes lumineuses numérotées impair sont décalées par rapport aux cartes de circuits imprimés de bandes lumineuses numérotées pair. Sur chaque carte de circuits imprimés, une partie à laquelle est soudée une DEL ou à laquelle sont soudés une DEL et un élément de commande, est conçue pour être relativement large, et tout ou partie de parties vides auxquelles aucun élément n'est soudé sont conçues pour être relativement étroites. Une partie relativement étroite d'une carte est présente entre des parties relativement plus larges de deux cartes qui lui sont horizontalement adjacentes. Le nombre de bandes lumineuses par mètre carré sur une carte de circuits imprimés à liaisons conjointes comprenant de multiples cartes de circuits imprimés, conçues et fabriquées de cette manière, est augmenté de 25 % au minimum, ce qui permet de réduire significativement les coûts. Après un soudage des éléments à la carte de circuits imprimés, une bande adhésive double face est collée sur sa surface arrière, puis la carte de circuits imprimés est découpée en de multiples bandes lumineuses uniques au moyen d'une matrice de coupe. La bande lumineuse unique présente les caractéristiques suivantes : une partie de la bande unique à laquelle est soudée une DEL est relativement large, et une partie de la bande unique sur laquelle n'est situé aucun élément est relativement étroite. De plus, sur des surfaces latérales de deux côtés dans une direction longitudinale, des surfaces latérales de deux côtés de la carte de circuits imprimés de la bande lumineuse et des surfaces latérales de deux côtés de la bande adhésive double face située sur la surface arrière de la bande lumineuse sont situées sur des surfaces de coupe respectives. La bande lumineuse de forme spéciale conçue et fabriquée de cette manière améliore le taux d'utilisation de la carte de circuits imprimés et de la bande adhésive double face, et réduit significativement les coûts.
