Abstract
A low-pressure discharge lamp with a double spiral shaped discharge tube including two spiral shaped tube portions. The tube portions define a central axis of the discharge tube. A cold chamber portion connects the ends of the spiral shaped tube portions. The cold chamber portion has a first transversal dimension substantially perpendicular to the central axis which is larger than the diameter of the tube portions. The cold chamber portion further has a second transversal dimension substantially parallel to the central axis. The second transversal dimension of the cold chamber portion substantially corresponds to the diameter of the tube portions.
