| description | Luminous sign animating device consisting of a rare gas discharge tube provided with an electrode at each of its ends, this device comprising a generator of signals with frequency lying between 5 and 100 KHz in order to power the said tube, characterised in that it further comprises a variable-gain amplifier (2) connected to the input of the generator (4) and a circuit (1) for controlling the variable- gain amplifier (2) as a function of the voltage desired at the output of the latter.
Dispositif d'animation d'enseigne lumineuse constitué par un tube à décharge à gaz rare pourvu d'une électrode à chacune de ses extrémités, ce dispositif comportant un générateur de signaux de fréquence comprise entre 5 et 100 KHz pour alimenter ledit tube, caractérisé en ce qu'il comporte en outre un amplificateur à gain variable (2) connecté à l'entrée dudit générateur (4) et un circuit (1) de commande dudit amplificateur à gain variable (2) en fonction de la tension souhaitée à la sortie de celui-ci. |
