Abstract

389,025. Electric lighting systems. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. Sept. 20, 1932, No. 26165. Convention date, Dec. 1, 1931. [Class 38 (iv).] A lighting installation, particularly suitable for road illumination, comprises a plurality of gas-filled discharge lamps each with an incandescent cathode and each operated through a transformer with the primary circuits of such transformers in series. In one arrangement, Fig. 1, each lamp comprises an envelope 1 with a filling of sodium vapour and a rare gas, a cathode 2 supplied with heating current from a portion of the secondary winding 5 of the corresponding transformer and two anodes 3 connected through resistances 4 one to each end of the winding 5, the primary windings 7 being connected in series and fed from a transformer 8. Each cathode is coated with an electron-emitting layer, e.g. of an alkaline earth oxide, to keep the temperature of electron emission low.. The resistances 4 may be arranged to heat the envelopes 1 to increase the vapour pressure. In another arrangement, Fig. 2, economy is effected by the use of autotransformers 9 each in series with a steadying resistance 13. In this case each lamp may comprise two cathodes 11 which may be heated indirectly or by connection, as shown, to end portions of the transformer windings and two anodes 12 which may each be connected as :shown to one pole wire of the adjacent cathode or may be supplied through separate conductors. The transformer windings between the points 15, 16, which are not traversed by the discharge current, may be of thinner wire than the rest of the windings. Preferably each transformer is bridged by normally open shunt which is closed automatically if the corresponding lamp becomes defective. To increase the number of lamps without increasing the tension of the feeding transformer 8, the supply conductors may be connected to tapping points on the autotransformer windings.
