Abstract:
(EN) The present invention relates to a dimming-type LED lighting apparatus having an electrolytic capacitor-less power supply device which senses and controls input voltage information of a primary side of a transformer, senses an input current thereof, and operates with reference to input power thereof. Therefore, the apparatus does not require a secondary-side electrolytic capacitor for stabilizing the output voltage and current thereof, and thus can improve the entire lifetime thereof. The LED lighting apparatus, which has an electrolytic capacitor-less power supply device for supplying power to an LED lighting, comprises: a voltage input unit for inputting a commercialized AC voltage; a transformer having a primary side connected to the voltage input unit and a secondary side connected to the LED lighting so as to drive the LED lighting; a power transistor connected between the primary side of the transformer and a ground terminal; a noise filter configured between the transformer and the LED lighting to remove noise included in power input to the LED lighting; a reference voltage generation unit for generating and outputting a commercialized AC voltage input through the voltage input unit, as a reference voltage; and a switching control unit for receiving, as an input, the reference voltage generated by the reference voltage generation unit and driving the power transistor.
(FR) La présente invention concerne un appareil d'éclairage à DEL du type à gradation possédant un dispositif d'alimentation électrique sans condensateur électrolytique qui détecte et commande des informations de tension d'entrée d'un côté primaire d'un transformateur, détecte un courant d'entrée de celui-ci, et fonctionne en fonction de la puissance d'entrée de celui-ci. Par conséquent, l'appareil ne nécessite pas de condensateur électrolytique côté secondaire pour stabiliser sa tension de sortie et son courant, et il peut ainsi prolongée sa durée de vie globale. L'appareil d'éclairage à DEL, qui possède un dispositif d'alimentation électrique sans condensateur électrolytique pour alimenter un élément d'éclairage à DEL, comprend : une unité d'entrée de tension pour l'entrée une tension alternative secteur ; un transformateur ayant un côté primaire connecté à l'unité d'entrée de tension et un côté secondaire connecté à l'élément d'éclairage à DEL de façon à commander l'élément d'éclairage à DEL ; un transistor de puissance connecté entre le côté primaire du transformateur et une borne de mise à la masse ; un filtre antibruit configuré entre le transformateur et l'élément d'éclairage à DEL pour éliminer le bruit inclus dans l'énergie fournie à l'élément d'éclairage à DEL ; une unité de génération de tension de référence pour générer et délivrer une tension alternative secteur d'entrée par l'intermédiaire de l'unité d'entrée de tension, en tant que tension de référence ; et une unité de commande de commutation destinée à recevoir, en tant qu'entrée, la tension de référence générée par l'unité de génération de tension de référence et commander le transistor de puissance.
