Abstract

L'invention concerne une lampe à décharge à basse pression, en particulier une lampe à substance luminescente ou une lampe compacte à substance luminescente, qui présente au moins un récipient de décharge (2) dont l'espace de décharge (6) reçoit deux enroulements d'électrode (10) reliés à des amenées de courant (28, 30) et au moins deux branches d'enroulement respectives (12, 14) dotées d'un matériau émetteur. Selon l'invention, au moins un support (16) d'enroulement électriquement isolé est prévu, celui-ci s'engage entre les branches d'enroulement (12, 14) et immobilise les enroulements d'électrode (10) dans le récipient de décharge (2) de telle sorte que les branches d'enroulement (12, 14) forment l'une avec l'autre un angle inférieur à 180°.
