Abstract

459,402. Discharge lamps. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London.-(Patent - Treuhand - Ges. f³r Elektrische Gl³hlampen; 11, Ehrenbergstrasse, Berlin) Nov. 25, 1935, No. 32652. [Class 39 (i)] In an electric discharge lamp wherein an electrode 7 is inserted through the side of the envelope 1 and near the closed end 2, a shield 10 surrounds the electrode and has its inner end bent towards the closed end, so that when a number of lamps are used end to end in a sign, the discharge appears continuous; the shield causes the discharge to pass to the closed end. A layer 11 of luminescent material may be provided on the envelope. The shield may be of metal, porcelain or opal glass. The envelope may be straight or curved.
