A gas discharge tube is controlled in intensity and in the length along such tube that is illuminated by providing digital control signals to an analog drive circuit connected to the high-voltage energization device for the tube. A pulse-width modulated digital control signal containing illumination length and intensity information is converted to ramp-shaped analog drive pulse that control the voltage at a high-voltage transformer secondary to which the gas discharge tube is connected. A manually actuatable keypad permits the user to enter the information that is then converted to the pulse-width modulated signal.
L'invention est un tube à décharge dont l'intensité lumineuse dans le sens longitudinal est contrôlée au moyen de signaux numériques transmis à un circuit d'attaque analogique connecté à son dispositif d'excitation haute tension. Un signal de commande numérique à impulsions modulées en durée contenant des informations sur la durée et l'intensité de l'éclairage est converti en impulsions d'attaque analogiques en rampe qui commandent la tension au secondaire d'un transformateur haute tension auquel le tube à décharge est connecté. Un clavier actionnable manuellement permet à l'utilisateur d'introduire des informations qui sont ensuite converties en un signal à modulation d'impulsions en durée.
