摘要:
The invention relates to the discharge tube of a compact fluorescent lamp which discharge tube, being sealed hermetically and provided with appropriate fill, comprises at least two tube portions connected with each other, and electrodes are placed at the ends of the first and last tube portions, and lead wires protrude through the glass wall of the discharge tube to the electrodes. The invention also relates to a method for closing at least one of the tube portions forming a part of the discharge tube of a compact fluorescent lamp. The essential feature of the discharge tube according to the invention is that at least one of these tube portions is closed by a curved surface having tangents which, starting from the axis of the tube portion and extending to the cylindrical wall thereof, make a monotonously decreasing angle with the axis of the tube portion.
