Title
(EN) REACTANCE LED (LIGHT-EMITTING DIODE) LIGHTING CURRENT CONTROL SCHEME
(FR) SYSTÈME DE COMMANDE DE COURANT D'ÉCLAIRAGE À DEL (DIODES ÉLECTROLUMINESCENTES) À RÉACTANCE
Abstract
(EN)
A new AC (alternating current) LED (light-emitting diode) lighting control/driver scheme is provided, and the scheme uses a reactive element for the purpose to produce the required LED lighting current. With monitoring and protection as inherent features in the present solution, the scheme is highly efficient, highly practical, and universally applicable to all AC based LED lighting applications.
(FR)
La présente invention concerne un nouveau système de commande et d'excitation d'éclairage à diodes électroluminescentes (DEL) à courant alternatif (CA). Le système utilise un élément réactif servant à produire le courant d'éclairage de DEL requis. Grâce aux caractéristiques inhérentes de surveillance et de protection offertes par la solution présente, le système fait preuve d'une efficacité élevée, d'un grand aspect pratique, et d'une applicabilité universelle pour toutes les applications d'éclairage à DEL basées sur le CA.
