Abstract

L'invention concerne les dispositifs de réglage de la lumière émise par des lampes de forte puissance. Le dispositif de l'invention comporte des circuits qui engendrent un signal 68 dont la forme et l'amplitude sont définies avec précision, et qui présente une relation de phase fixe avec la tension du secteur. La forme de ce signal détermine la caractéristique de transfert entre le signal de commande et la tension effective qui est appliquée à la lampe commandée. Application aux installations d'éclairage de studios de télévision.
