Abstract

1. Discharge lamp of the cold cathode tube type, the tube of which is, between the two electrodes (4), folded over or curved according to two sheets (1a, 1b) located into two closely parallel planes, the layout of the tube in one sheet being intercalated with the layout of the tube in the other sheet so as to obtain a uniform luminosity on all the surface of the lamp.
