Abstract

L'invention concerne un dispositif à source de lumière électrique d'éclairage multisortie comportant un circuit de filtrage actif, un circuit de filtrage de redressement haute fréquence, un circuit de commande d'alimentation électrique à commutateur haute fréquence, un circuit de déphasage à retard d'impulsion, trois circuits de sortie électrique de découpage et trois charges de source de lumière électrique. Le bloc d'alimentation électrique CA alimente le circuit de filtrage de redressement haute fréquence par l'intermédiaire du circuit de filtrage actif. Le circuit de commande d'alimentation électrique à commutateur haute fréquence est relié au circuit de filtrage actif et au circuit de déphasage à retard d'impulsion. Le circuit de commande d'alimentation électrique à commutateur haute fréquence ajuste la fréquence d'oscillation en fonction des différences des charges de puissance de lumière électrique afin de générer deux sorties à impulsions positives verrouillées, afin de retarder et décaler une phase vers deux sorties verrouillées via le circuit de déphasage à retard d'impulsion, et produit une tension et un courant haute fréquence multisortie via le circuit de découpage haute puissance. Le dispositif peut de manière efficace supprimer l'effet stroboscopique de la source de lumière électrique et améliorer la qualité de l'éclairage. Le dispositif réduit la composante d'onde harmonique du courant d'entrée, de telle sorte que la source de lumière électrique peut atteindre un rapport de conversion photoélectrique plus élevé en utilisant moins de courant, afin d'économiser de l'énergie électrique.
