Title (EN) DISCHARGE LAMP OPERATION DEVICE AND BULB-SHAPED FLUORESCENT LAMP
(FR) DISPOSITIF DE FONCTIONNEMENT POUR LAMPE À DÉCHARGE ET LAMPE FLUORESCENTE EN FORME D’AMPOULE

Abstract:
(EN) By using a ceramic chip capacitor, it is possible to reduce the size of a discharge lamp operation device of a bulb-shaped fluorescent lamp. Even when the ceramic chip capacitor is short-circuited, it is possible to suppress excessive temperature increase. The ceramic chip capacitor is a capacitor (C5) for preheating and start contributing to the resonance of the discharge lamp device connected in parallel to a light emitting tube (4). The capacitor (C5) is located between wrapping pins (61, 61) and mounted on the surface of a substrate (58). An inverter circuit limits the current supplied to the ceramic chip capacitor to the normal current multiplied by 1.5 or below even when the capacitor (C5) is short-circuited, thereby preventing excessive temperature increase of the capacitor (C5).
(FR) La présente invention concerne un dispositif de fonctionnement pour lampe à décharge d’une lampe fluorescente en forme d’ampoule, dispositif dont la taille peut être réduite en utilisant à un condensateur-pastille en céramique. Même lorsque le condensateur-pastille en céramique est court-circuité, une augmentation thermale excessive peut être évitée. Le condensateur-pastille en céramique est un condensateur (C5) pour le préchauffage et commence à contribuer à la résonance du dispositif pour lampe à décharge connecté en parallèle à un tube émetteur lumineux (4). Le condensateur (C5) est placé entre des broches enroulées (61, 61) et est monté sur la surface d’un substrat (58). Un circuit inverseur limite le courant alimentant le condensateur-pastille en céramique au courant normal multiplié par au plus 1,5 même lorsque le condensateur (C5) est court-circuité, évitant ainsi une augmentation de température excessive du condensateur (C5).
