Abstract

L’invention proposée permet de réaliser un module lumineux compact pour un véhicule automobile, dans lequel le l’empreinte spatiale du circuit convertisseur alimentant une source lumineuse est fortement réduite par rapport à des solutions connues. En accord avec des modes de réalisation préférés, la compatibilité électromagnétique du module par rapport à des circuit électroniques externes est augmentée par rapport à des solutions connues.
