(FR) APPAREIL D'ÉCLAIRAGE, CIRCUIT D'ATTAQUE ET PROCÉDÉ D'ATTAQUE CORRESPONDANT
Abstract:
(EN) A lighting apparatus, a driving circuit and driving method thereof are provided. The lighting apparatus comprises a plurality groups of lighting elements and a driving circuit. Each group of lighting elements comprises at least one lighting element (D11, D12, D13, D21, D22, D23, …, DX1, DX2, DX3). Each lighting element (D11, D12, D13, D21, D22, D23, …, DX1, DX2, DX3) in a same group has a cathode connected to a common cathode node (N1, N2, …, NX). The driving circuit comprises a plurality of voltage sources (V1, V2, V3), each having a terminal connected to an anode of a respective lighting element (D11, D12, D13, D21, D22, D23, …, DX1, DX2, DX3) in each group of lighting elements; and a plurality of current sources (I1, I2, …, IX), each having a terminal connected to the common cathode node (N1, N2, …, NX) of a respective group of lighting element.
(FR) La présente invention concerne un appareil d'éclairage, un circuit d'attaque et un procédé d'attaque correspondant. L'appareil d'éclairage comprend une pluralité de groupes d'éléments d'éclairage et un circuit d'attaque. Chaque groupe d'éléments d'éclairage comprend au moins un élément d'éclairage (D11, D12, D13, D21, D22, D23, …, DX1, DX2, DX3). Chaque élément d'éclairage (D11, D12, D13, D21, D22, D23, …, DX1, DX2, DX3) dans un même groupe comporte une cathode connectée à un nœud de cathode commun (N1, N2, …, NX). Le circuit d'attaque comporte une pluralité de sources de tension (V1. V2. V3) ayant chacune une borne connectée à une anode d'un élément d'éclairage respectif (D11, D12, D13, D21, D22, D23, …, DX1, DX2, DX3) dans chaque groupe d'éléments d'éclairage; une pluralité de sources de courant (I1, I2, …, IX), ayant chacune une borne connectée au nœud de cathode commun (N1, N2, …, NX) d'un groupe respectif d'éléments d'éclairage.
