CA 2532834

Various embodiments for an LED decorative light string are described herein that generally comprise one or more branch circuits that are parallelly connected with each other, and then connected to a common power supply wire for importing an operational voltage. A given branch circuit comprises a plurality of light groups serially connected in turn. A given light group can include two or more LEDs, wherein at least one LED is parallelly connected with at least one other LED in a reverse direction. The various LED decorative light strings described herein are more economical, more reliable in performance, and have a longer life-span than conventional LED light strings.

L'invention concerne divers modes de réalisation d'une guirlande lumineuse décorative généralement constituée d'un ou de plusieurs circuits de dérivation. Ces circuits sont connectés en parallèle l'un à l'autre et sont reliés à un fil d'alimentation électrique commun qui permet l'obtention d'une tension efficace. Un circuit de dérivation donné comprend plusieurs groupes d'éclairage connectés en série. Un groupe d'éclairage donné peut comprendre deux DEL ou plus, dont au moins une est reliée en parallèle à au moins une autre DEL en sens inverse. Les guirlandes lumineuses décoratives à DEL décrites sont plus économiques et plus fiables et ont une meilleure durée de vie que les guirlandes lumineuses décoratives à DEL classiques.
