Abstract: The fluorescent lamp consists of a discharge space outwardly limited by a glass tube and of discharge electrodes as well as of an elongated inner element that limits inwardly the discharge space. The entire inner wall of the glass tube and the outer wall of the inner element are covered with a layer of fluorescent material and inside of the inner element, at least along a part of its entire length, an electrically conductive material is placed that is connected with a discharge electrode. In order to improve the lamp efficiency and also to reduce the cost of manufacture of such a lamp, the lamp according to the invention is so designed that the inner element is a support for the capacitor elements which are placed in the inner space of the inner element. The capacitor elements extend at least along a part of the entire length of the inner element. An electrical potential emitting from the said capacitor elements acts perpendicular against the known discharge current of the lamp.
