Title (EN) SINGLE DRIVER FOR MULTIPLE LIGHT EMITTING DIODES
(FR) PILOTE UNIQUE POUR DIODES ELECTROLUMINESCENTES MULTIPLES
Abstract: front page image
(EN)A LED driver circuit (70, 80) employs a power source (IS, VS) for providing power at a power conversion frequency to a switching LED cell (30-32, 40-42). The switching LED cell (30-32, 40-42) switches between a radiating mode and a disabled mode at a LED driving frequency. In the radiating mode, the switching LED cell (30-32, 40-42) controls a flow of a LED current from the power source (IS, VS) through one or more LEDs (L11-LXY) to radiate a color of light from the LEDs (L11-LXY). In the disabled mode, the switching LED cell (30-32, 40-42) impedes the flow of the LED current from the power source (IS, VS) through the LEDs (L11-LXY).
(FR)Circuit pilote (70, 80) pour diodes électroluminescentes, utilisant une source d'énergie (IS, VS) alimentant une cellule DEL de commutation (30-32, 40-42) en énergie à une fréquence de conversion de courant. La cellule DEL de commutation (30-32, 40-42) bascule entre un mode de rayonnement et un mode désactivé à une fréquence de pilotage de DEL. En mode rayonnement, la cellule DEL de commutation (30-32, 40-42) régule un courant DEL partant de la source d'énergie (IS, VS) et traversant une ou plusieurs DEL (L11-LXY) afin de provoquer le rayonnement par les DEL (L11-LXY) d'une lumière colorée. En mode désactivé, la cellule DEL de commutation (30-32, 40-42) entrave le courant DEL partant de la source d'énergie (IS, VS) et traversant les DEL (L11-LXY).
