Abstract

987,939. Discharge lamps. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. April 9, 1963 [April 12, 1962], No. 14136/63. Heading H1D. A discharge lamp containing e.g. sodium or rare gas has an ohmic resistance formed by a layer 30 (e.g. of tin oxide) on the vessel 21 in series with the discharge to stabilize the discharge; the layer 30 is transparent to at least 50% of the visible or u.v. radiation from the lamp, but may reflect most of the infra-red radiation. The resistance layer may be on the wall of the discharge vessel (as illustrated) or on the wall of a surrounding envelope 22. The resistance layer heats the tube, and may assist starting. Specifications 386,586 and 987,938 are referred to.
