Title
(EN) POWER SUPPLY FOR AN LED LIGHTING UNIT
(FR) ALIMENTATION ÉLECTRIQUE POUR UNITÉ D'ÉCLAIRAGE À DEL
Abstract
(EN)
A power supply for an LED lighting unit. The power supply comprises two power converters, either of which may provide the power to be drawn by components of the LED lighting unit. In particular, a controller of the power supply controls which power converter converts a mains power supply to a power level for a connected LED lighting unit. The two power converters are designed to be efficient when providing different power levels.
(FR)
L'invention concerne une alimentation électrique pour une unité d'éclairage à DEL. L'alimentation électrique comprend deux convertisseurs de puissance, l'un ou l'autre pouvant fournir l'énergie à être consommée par des composants de l'unité d'éclairage à DEL. En particulier, un dispositif de commande de l'alimentation électrique commande quel convertisseur de puissance qui convertit une alimentation secteur en un niveau de puissance pour une unité d'éclairage à DEL connectée. Les deux convertisseurs de puissance sont conçus pour être efficaces lors de la fourniture de différents niveaux de puissance.
