Abstract

L'addition concerne un système d'allumage optoélectronique utilisant une bobine d'allumage, et comprenant une lampe solide à l'arsénure de gallium, un élément occultateur, un phototransistor et un circuit d'allumage à montages Darlington, connectés entre le phototransistor et l'enroulement primaire de la bobine d'allumage. Selon l'addition, une diode inverse D4 est connectée à travers la lampe à arsénure de gallium 1; un condensateur C est connecté en parallèle avec les diodes Zener de protection Z2 et Z3 associées aux montages Darlington Q1 et Q2, et une diode de Schottky SD est connectée en direction directe entre la base et le collecteur du phototransistor 2. L'addition s'applique notamment aux moteurs à combustion interne.The addition relates to an optoelectronic ignition system using an ignition coil, and comprising a solid gallium arsenide lamp, a occulting element, a phototransistor and a Darlington circuit ignition circuit, connected between the phototransistor and the primary winding of the ignition coil. According to the addition, a reverse diode D4 is connected through the gallium arsenide lamp 1; a capacitor C is connected in parallel with the protection Zener diodes Z2 and Z3 associated with the Darlington assemblies Q1 and Q2, and a Schottky diode SD is connected in the direct direction between the base and the collector of the phototransistor 2. The addition s' applies in particular to internal combustion engines.
