Dispositif d'alimentation de secours d'un luminaire fluorescentEmergency power supply of a fluorescent luminaire
L'invention concerne un dispositif d'alimentation de secours d'un luminaire fluorescent, permettant d'alimenter le luminaire sous The invention relates to a device for back-up power supply of a fluorescent luminaire, making it possible to power the luminaire under

Un luminaire fluorescent est constitué par un tube fluorescent équipé d'un ballast et d'un starter; il peut être compensé par un A fluorescent fixture consists of a fluorescent tube equipped with a ballast and a starter; it can be offset by a

On connait deux solutions classiques d'onduleurs pour ali- We know two conventional UPS solutions for

Ces deux solutions permettant l'alimentation du luminaire mais non l'amorçage du tube fluorescent du fait de l'insuffisance du courant de chauffage des filaments du tube fluorescent. Afin de contourner cette impossibilité il est nécessaire d'alimenter d'abord le tube fluorescent à pleine puissance afin d'en assurer l'amorçage puis de réduire la puissance soit par modification de la fréquence soit par modification de la tension de l'onduleur. Bien évidemment la commutation entre l'alimentation à la pleine puissance et le régime d'alimentation à puissance réduite ne peut avoir lieu qu'après amorçage du tube fluorescent; pour cela on peut effectuer la commutation soit après un temps déterminé suffisant pour que l'amorçage ait eu lieu, soit par détectio.n de l'amorçage du tube fluorescent. Dans le cas o la commutation est effectuée après un temps déterminé ce temps doit être suffisant pour assurer l'amorçage These two solutions allow the supply of the luminaire but not the priming of the fluorescent tube due to insufficient heating current filaments of the fluorescent tube. In order to circumvent this impossibility, it is necessary to supply the fluorescent tube firstly at full power in order to prime it and then to reduce the power either by modifying the frequency or by modifying the voltage of the inverter. Of course, switching between the power supply at full power and the power regime at reduced power can take place only after priming of the fluorescent tube; for this, it is possible to switch either after a predetermined time sufficient for the priming to take place, or by detectio.n of the priming of the fluorescent tube. In the case where the commutation is carried out after a determined time this time must be sufficient to ensure the priming

Le dispositif de blocage 15 assure le blocage du dispositif de commande 2 pendant le transfert de l'énergie emmagasinée dans l'en- roulement primaire El, donc pendant le temps de récupération t2. En effet quand le transistor T3 cesse d'être conducteur au bout du temps tl, la tension aux bornes de l'enroulement primaire El s'inverse et le transistor T4 devient conducteur; son collecteur est porté au potentiel du fil F2, ce qui porte également la borne 4 The locking device 15 locks the control device 2 during the transfer of the energy stored in the primary winding El, thus during the recovery time t2. Indeed, when the transistor T3 ceases to be conducting at the end of the time t1, the voltage across the primary winding El is reversed and the transistor T4 becomes conductive; its collector is brought to the potential of the wire F2, which also carries the terminal 4
