Abstract
1400976 Metal-vapour lamps PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 16 March 1973 [20 March 1972] 12732/73 Heading H1D In a high-pressure mercury vapour discharge lamp having a discharge vessel whose wall is subjected during operation of the lamp to a power of between 10 and 100 W per sq. cm. the discharge vessel contains a rare gas as an ignition gas, at least one of the halogens I, Br or Cl, from 0À5 to 40 mg. of Hg (up to 50% by weight of which may be replaced by Cd per cc. of the internal volume of the discharge vessel, sufficient sodium halide that during operation of the lamp unevaporated sodium halide is present in the discharge vessel, a quantity of Tl which is from 0À25 to 25% by weight of the quantity of Hg, or of Hg plus Cd, a quantity of Ca which is from 1 to 30% by weight of the quantity of Hg, or of Hg plus Cd and optionally a quantity of In which is up to 15% by weight of the quantity of Hg, or of Hg plus Cd, the quantity of halogen expressed in chemical equivalents being at least equal to the total quantity of Na and Ca expressed in chemical equivalents and not more than twice the total quantity of Na, Ca, T1 and In expressed in chemical equivalents. The relevant halogen may be introduced into the lamp as one or more halides of the above mentioned elements. The halide is preferably the iodide, and the ignition gas may be A at a pressure of up to 20 torr. or a mixture of 99% Ne and 1% A at a pressure of up to 40 torr. The discharge tube may contain additionally one or more of the elements Sc, Y, La and the lanthanides in a quantity of between 0À1 to 40% by weight of the quantity of Hg or of Hg plus Cd, and Nd or Dy in a quantity of between 3 to 40%.
