A fluorescent lamp ballast having an integrated circuit driver which avoids lamp flicker caused by momentary dips in mains voltage during lamp turn on. The anti-flicker scheme within the fluorescent lamp ballast driver distinguishes between operating conditions during and after preheat of the lamp electrodes. By maintaining the voltage for powering the integrated circuit driver above its minimum threshold, the driver does not momentarily shut off during lamp turn on.
L'invention concerne un ballast de lampe fluorescente comportant un organe de commande à circuit intégré, qui permet d'éviter un tremblotement de la lampe provoqué par des chutes momentanées de la tension de secteur pendant l'allumage de la lampe. Le système anti-tremblotement se trouvant dans l'organe de commande du ballast de lampe fluorescente permet de faire une distinction entre des conditions de fonctionnement pendant et après préchauffage des électrodes de la lampe. En maintenant une tension d'alimentation de l'organe de commande à circuit intégré à un niveau supérieur à son seuil minimum, on évite une coupure momentanée de courant en direction de l'organe de commande pendant l'allumage de la lampe.
