Abstract

En résumé, l'invention concerne une lampe à décharge basse pression qui comporte une électrode comprenant plusieurs canaux et un régulateur de courant pour réguler la distribution de courant à travers ces canaux. La régulation de courant peut être assurée à l'aide d'un réseau approprié d'impédances dans les connexions électriques de l'électrode. Ceci permet un degré élevé de régulation de la manière dont l'énergie électrique est couplée dans le remplissage de gaz, permettant aux pertes d'extrémité d'être réduites. De plus, le régulateur de courant peut également être utilisé pour créer une large plage de distributions de lumière émise par la lampe à décharge.
