摘要： The invention relates to a single-ended discharge lamp comprising a discharge tube bordering a discharge space (14) and sealed in a gas-tight manner at its ends and also comprising electrodes (30), wherien the discharge tube has at least two straight tube portions (12) and a bent connection member (11) between at least some of the adjacent straight tube portions. The bent connection member has an arc-shaped outer (11a) and an arc-shaped inner bordering wall (11b), an indentation (11c) narrowing the cross-section of the discharge space is formed in the outer boardering wall and the bent connection member has bulged dome portions (11d,11e) between its ends connecting to the straight tube portion and the narrowing indentation. The largest cross-section (A2) inside the tube wall of at least one of the dome portions (11d) is at least 1.8 times but at maximum 2.2 times the smallest cross-section (A3) inside the tube wall between the arc-shaped inner bordering wall (11b) of the bent connection member (11) and the narrowing indentation (11c).
