Title (EN) LIGHT-EMITTING DIODE DIMMING DRIVE CIRCUIT
(FR) CIRCUIT D'ATTAQUE À GRADATION D'INTENSITÉ LUMINEUSE DE DIODE ÉLECTROLUMINESCENTE
(ZH) 发光二极管调光驱动电路
Abstract:
(EN) The present invention provides a light-emitting diode (LED) dimming drive circuit. The LED dimming drive circuit comprises: a bidirectional triode thyristor (TRIAC) dimmer, used for adjusting an inputted alternating voltage; and a self-excited oscillation pulsed converter (RCC), connected to the TRIAC dimmer, and used for adjusting an alternating voltage from the TRIAC dimmer and providing a drive current for an LED load.
(FR) La présente invention concerne un circuit d'attaque à gradation d'intensité lumineuse de diode électroluminescente (DEL). Le circuit d'attaque à gradation d'intensité lumineuse de DEL comprend : un gradateur à thyristor triode bidirectionnel (TRIAC), utilisé pour régler une tension alternative d'entrée ; et un convertisseur pulsé à oscillation auto-excitée (RCC), connecté au gradateur à TRIAC, et utilisé pour régler une tension alternative provenant du gradateur à TRIAC et fournir un courant d'attaque destiné à une charge DEL.
(ZH) 本发明提供一种发光二极管(LED)调光驱动电路。该LED调光驱动电路包括:双向可控硅(TRIAC)调光器,用于调节输入的交流电压;与该TRIAC调光器连接的自激振荡脉冲变换器(RCC),用于调节来自TRIAC调光器的交流电压,为LED负载提供驱动电流。
