Abstract
627,193. Supply systems for space discharge lamps; protective arrangements. GENERAL ELECTRIC CO., Ltd., and WILLOUGHBY, A. H. Aug. 11, 1947, No. 22252. [Class 38 (iv)] In a circuit arrangement for an electric discharge lamp 1 operating from a D.C. supply in which the stabilizing impedance is substantially resistive and the starting voltage is provided by an inductance coil, such as 4, included in at least one supply lead, a condenser 7 is connected across the supply leads so that no inductance coil lies between it and a supply terminal ; no undesirable voltages are then developed across the supply terminals when the lamp is started.
