Abstract

DISPOSITIF AUTONOME PRODUCTEUR DE FLASCHES ELECTROLUMINESCENTS. CE DISPOSITIF COMPREND UN CIRCUIT MULTIVIBRATEUR 1 ALIMENTE PAR UNE SOURCE DE COURANT CONTINU, ET ASSOCIEE A UNE DIODE ELECTROLUMINESCENTE 2. LE MULTIVIBRATEUR 1 COMPORTE UN CIRCUIT RESISTANCE R4-CONDENSATEUR 11 A CONSTANTE DE TEMPS REGLABLE, QUI PILOTE UN TRANSISTOR 3 MONTE EN SERIE AVEC LA DIODE ELECTROLUMINESCENTE 2, LA CONSTANTE DE TEMPS PRECITEE DETERMINANT LA FREQUENCE DES FLASHES EMIS PAR LA DIODE. CE DISPOSITIF AUTONOME PEUT PRODUIRE UNE SUCCESSION DE FLASHES LUMINEUX PENDANT UNE TRES LONGUE DUREE, AVEC UNE TRES FAIBLE CONSOMMATION DE COURANT AU REPOS, IL EST UTILISABLE NOTAMMENT DANS LA PUBLICITE.
