L'INVENTION CONCERNE LES DISPOSITIFS PHOTOGRAPHIQUES A LAMPES A ECLAIR COMMANDEES ELECTRIQUEMENT.CES DISPOSITIFS COMPRENNENT UNE CARTE 27 CONSTITUEE PAR UNE BANDE ISOLANTE 29 SUR L'UNE 33 DES FACES DE LAQUELLE EST IMPRIME LE CIRCUIT ELECTRIQUE DE COMMANDE 31 DES LAMPES 13, ET UNE PLURALITE DE LAMPES A ECLAIR CONSTITUEES CHACUNE PAR UNE ENVELOPPE TRANSPARENTE D'OU FONT SAILLIE DEUX FILS CONDUCTEURS 39, 44.SELON L'INVENTION, CES DERNIERS SONT FIXES A LA MANIERE D'UNE AGRAFE DE PART ET D'AUTRE DE LA BANDE ISOLANTE DE FACON A ASSURER LA FIXATION DES LAMPES ET LA CONNEXION ELECTRIQUE DE CELLES-CI AU CIRCUIT IMPRIME 31. A multilamp photoflash unit which includes an elongated housing, a circuit board located within a longitudinal channel within the housing, and several (e.g. six) electrically-activated flashlamps. The flashlamps utilize preformed lead-in wires which are clamped to peripheral side walls of the circuit board's insulative strip members to both secure the lamps in a linear orientation and to electrically connect portions of the lead-in wires to selected areas of the board's lamp-firing circuitry.
