CIRCUIT DE RECHARGE DE PILES COMPORTANT DES MOYENS INDICATEURS

L'INVENTION CONCERNE UN CIRCUIT DE RECHARGE DE PILES COMPORTANT DES MOYENS INDICATEURS.DANS CE CIRCUIT COMPORTANT UNE DIODE 12 ET UNE BATTERIE 14 BRANCHEES EN SERIE ET MONTEES EN PARALLELE AVEC UNE SOURCE D'ALIMENTATION EN ENERGIE 16, IL EST PREVU DES PREMIERS MOYENS 22A, 24 RACCORDES AUX BORNES DE LADITE SOURCE 16 ET SERVANT A INDIQUER LA PRESENCE D'UN COURANT DE CHARGE FOURNI PAR CETTE SOURCE, DES SECONDS MOYENS INDICATEURS 22B, 28 RACCORDES ENTRE LADITE SOURCE ET LA JONCTION DE LA DIODE ET DE LA PILE ET SERVANT A INDIQUER LA PRESENCE D'UN COURANT DE CHARGE DELIVRE PAR LA PILE, ET UN TRANSISTOR 30 BRANCHE ENTRE LADITE SOURCE ET LESDITS SECONDS MOYENS INDICATEURS ET QUI EST POLARISEE PAR LEDIT COURANT DE CHARGE DE MANIERE A EMPECHER L'ALIMENTATION DE CES MOYENS.APPLICATION NOTAMMENT AUX CHARGEURS DE PILES POUR LAMPES TORCHES RECHARGEABLES. A recharging circuit including a diode and a battery serially connected and coupled in parallel to a power source includes (a) a first indicator connected across the power source and illuminated by a charging current delivered by the power source; (b) a second indicator connected between the power source and the junction of the battery and diode, and which is illuminated by discharge current delivered by the battery in the absence of charging current from the power source, and (c) a transistor coupled across the power source and to the second indicator, and being biased by charging current so as to prevent illuminated of the second indicator. The recharging circuit is included in a rechargeable flashlight and the first and second indicators are formed by a single bi-color light emitting diode.
