Abstract
Improvements introduced in the main patent object, that is, in an electronic fluorescent lighting lamp in which two gratings are interposed between the cathode and the anode in which one rises to the potential of the cathode or to a slightly negative potential in relation to it and the other rises to a positive potential in relation to the cathode and in which these two bars have substantially the same step and the bars or elements of the positive grid are located in the electronic shadow of the grid at zero or negative potential characterized by the fact that the cathode and the aligned lattices interposed between it and the anode have a form such that the locus of the points located at the critical distance is very close to the anode and appreciably take the form of the latter.
