Abstract

The mfr. is effected in 3 successive stages, in which a linear lamp tube containing a glow resistance is filled with a gas at a cold pressure of not higher than 1.5 bar, before it is locally heated and then bent into the required shape, with a working filling pressure of about 1 bar maintained during the localised heating and bending. Pref. the cold filling pressure is between 600 and 800 mbar, with part of the lamp tube cooled during the localised heating and bending steps, for maintaining the required working filling pressure. <IMAGE>
