ABSTRACT: Incandescent lamps according to the invention have hollow cylindrical filaments which are constructed from transversal strips each traversing at least for the greater part the circumference of the cylinder at a distance from each other and of longitudinal strips which connect the transversal strips together. The strips constitute elec- trically parallel current paths. As compared with known filaments, those accor- ding to the invention have numerous advantages: a great resistance to deformation, a low sensitivity for evolving hot spots, a low weight and a large compactness. -21-
