Title (EN) DRIVING CIRCUIT FOR HIGH-POWERED LIGHT EMITTING DIODE
(FR) CIRCUIT DE COMMANDE POUR UNE DIODE ÉLECTROLUMINESCENTE DE FORTE PUISSANCE
Abstract: front page image
(EN)An LED lamp for an appliance receiving line voltage uses a phase control circuit blocking a predetermined phase angle of the line voltage to reduce average voltage to be consistent with the power demands of the LEDs. A current control circuit augments the phase control circuit to provide the necessary precision in current control.
(FR)La présente invention concerne une lampe à DEL pour un appareil électrique recevant une tension de ligne, la lampe utilisant un circuit de commande de phase bloquant un angle de phase prédéfini de la tension de ligne afin de réduire la tension moyenne pour qu’elle soit cohérente avec les demandes énergétiques des DEL. Un circuit de commande de courant augmente le circuit de commande de phase pour fournir la précision nécessaire à la commande de courant.
