Abstract

La connaissance générale de circuits électriques et de sécurité électrique est nécessaire pour remplacer une lampe fluorescente par un éclairage à DEL. En général, la plupart des usagers n'ont pas les connaissances pour modifier des circuits électriques, et sont particulièrement à la merci d'un accident lié à la sécurité. La présente invention simplifie le processus d'installation par remplacement d'une lampe fluorescente par un éclairage à DEL à une certaine position de la lampe fluorescente sans changer les circuits internes d'un dispositif de lampe fluorescente. Par conséquent, la présente invention permet à des non spécialistes de réaliser cette opération facilement et de faire une économie d'énergie sans avoir recours à l'aide d'un expert pour remplacer la lampe fluorescente par un éclairage à DEL. En particulier, la présente invention permet d'économiser de l'énergie de manière intelligente et de faire des économies d'électricité efficacement au moyen de commandes MARCHE/ARRÊT faisant intervenir un capteur de détection d'objet mobile monté de manière additionnelle ainsi que la luminosité de l'environnement. La présente invention permet en outre d'économiser de l'électricité de diverses manières par mise sous tension/hors tension facilitée de l'éclairage à DEL au moyen d'une télécommande à infrarouge, et, à la convenance de chacun, de prévenir l'occurrence d'un état sous tension continu de l'éclairage, qui s'avère fastidieux.
