Abstract

L’invention concerne une ampoule à DEL à extinction retardée, l’ampoule restant allumée pendant un certain intervalle de temps après coupure de son alimentation. L’invention concerne plus particulièrement l’utilisation d’un condensateur monté en parallèle avec au moins une série ou une pluralité de DEL de manière à produire une lumière d’intensité décroissante.
