Abstract: There is disclosed a method for forming a discharge tube for a low-pressure discharge lamp. In the method, an end of a section of the discharge tube is fastened with first clamping means, and a second end of the section in held in an oriented position. The section is heated to a softening temperature, and a bending moment is exerted on the section between the first end and the second end for achieving the desired radius or direction of curvature of the section. The holding of the second end of the section and the exertion of the bending moment on the section are effected at least partly with another re-solidified section of the discharge tube which is adjacent to the softened first section. An apparatus for performing the method is also disclosed. The apparatus comprises first and second clamping means for positioning the ends of a bending section of the discharge tube in an oriented position relative to each other, and for exerting a bending moment on the ends. The second clamping means is also used for positioning the ends of a starting bending section relative to each other. Heating means are provided for heating the bending section to a softening temperature, and controllable support means for positioning the first and second clamping means. Control means are used for synchronizing the operation of the controllable support means. The first and second clamping means and the heating means are suitable for achieving a desired radius or direction of curvature of the bending sections heated to the softening temperature.

Abstract: This invention concerns a compact fluorescent lamp with a double helix shaped discharge tube in which the two strands of the helix are constituted by two helix shaped tube portions. These tube portions define a central axis of the discharge tube. The double helix formed by the discharge tube has a central section and a first end section. These sections are defined along the central axis, and the lamp base for receiving ends of the tube portions is disposed at the first end section. An inner diameter of the central section of the helix is larger than an inner diameter of the first end section. The invention further relates to a method and apparatus for manufacturing coiled shaped discharge tubes, in particular the above described discharge tube of the discharge lamp. A radially segmented molding core is used for manufacturing the discharge tube. Once the coiling of the discharge tube on the molding core is completed, the segmented molding core is shrunk radially, and then is withdrawn from the coiled discharge tube axially.
