Abstract: front page image
(EN)Disclosed is a smart dimming converter apparatus. The smart dimming converter apparatus of the present invention comprises: a power supply unit which receives commercial alternating current power inputted thereto, stabilizes and rectifies the inputted power, and actively compensates for a power factor and outputs direct current power; a pulse-width control unit which switches the direct current power outputted from the power supply unit by pulse-width modulation, and outputs the switched direct current power; a DC-DC converter unit which receives the direct current power outputted from the pulse-width control unit and inputted thereto, and converts the inputted direct current power to direct current voltage for driving an LED; and an output current smoothing unit, which removes the alternating current component from the direct current voltage outputted from the DC-DC converter unit, converts the voltage to the voltage having a current of an average value, and outputs the converted voltage to an LED light. According to the present invention, the brightness of the LED light can be adjusted while preventing a flickering phenomenon even in the event of low current.
(FR)La présente invention concerne un appareil intelligent de conversion de la gradation de l'intensité lumineuse. L'appareil intelligent de conversion de la gradation de l'intensité lumineuse selon la présente invention comprend : une unité d'alimentation recevant un courant alternatif commercial entrant dans celle-ci, stabilisant et redressant le courant entré, compensant activement une correction du facteur, et délivrant un courant continu; une unité de commande de largeur d'impulsion commutant le courant continu délivré par l'unité d'alimentation par une modulation de largeur d'impulsion, et délivrant le courant continu commuté; une unité de conversion CC-CC recevant le courant continu délivré par l'unité de commande de largeur d'impulsion et entrant dans celle-ci, et convertissant le courant continu entré en tension de courant continu pour piloter une DEL; et une unité de filtrage de courant de sortie éliminant la composante de courant alternatif de la tension de courant continu délivrée par l'unité de conversion CC, convertissant la tension en tension présentant un courant ayant une valeur moyenne, et délivrant la tension convertie à une lumière à DEL. Selon la présente invention, la luminosité de la lumière à DEL peut être réglée tout en empêchant un phénomène d'oscillation y compris en cas de faible courant.
(KO)스마트 디밍 컨버터 장치가 개시된다. 본 발명은 상용의 교류 전원을 입력하고 안정화시켜 정류하며 역률을 능동적으로 보상하여 직류전원으로 출력하는 전원부, 전원부의 직류전원을 펄스폭변조 방식으로 스위칭 시켜 출력하는 펄스폭제어부, 펄스폭제어부가 출력한 직류전원을 입력하고 엘이디를 구동하는 직류 전압으로 변환하는 DC-DC 컨버터부 및 DC-DC 컨버터부가 출력하는 직류 전류에 포함된 교류성분을 제거하고 평균값의 전류로 변환하여 엘이디 전등에 출력하는 출력전류평활부를 포함하는 특징에 의하여 엘이디의 밝기를 조절하면서 낮은 전류의 경우에도 플리커 현상이 발생하지 않는 효과가 있다.
