Title: Improvements in and relating to electric gaseous discharge illuminating devices
IPC: C09K11/08
Filed: 1938-06-08
Abstract: 516,868. Metal-vapour lamps. BRITISH THOMSON-HOUSTON CO., Ltd. June 8, 1938, No. 17065. Convention date, June 22, 1937. [Class 39 (i)] A gaseous discharge lamp producing light at least in part by fluorescence comprises an envelope containing electrodes and a gaseous atmosphere capable of emitting ultra-violet radiation when excited, and an internal coating on the envelope of a fluorescent material comprising magnesium oxide and tungsten oxide substantially in the proportions of the formula Mg2WO5. The material may also contain an activator consisting of an oxide of cadmium, lead, bismuth, thorium, or cerium, in such proportion that the metal component of the activator is from .05 to .5 per cent. of the magnesium oxide. It may be prepared by mixing substantially 2.9 parts of tungsten oxide with 1 part of magnesium oxide, both having been purified to a high degree, together with a compound of one of the activator metals in such amount that the metal component is from .05 to .5 per cent. of the magnesium oxide, heating the mixture to about 150‹C. until it changes from yellow to white, then slowly raising it to 850 to 900‹C., then pulverizing the product, again slowly increasing the temperature to approximately 1,150‹C., and finally slowly cooling to 1,000‹C. The resulting powder may be made into a paint by forming a suspension of it in a mixture of amyl acetate, butyl acetate, and high viscosity nitrocellulose, a coating of this paint being baked on to the inner face of the tubular envelope of the lamp. The lamp shown comprises a cathode 2 having a core 4 formed by a closed turn of tungsten wire with coating 7 of alkaline earth compounds on which is carried a helix 6 of tungsten wire. The coating fills the interstices between the turns of the helix, and is preferably formed of a mixture of barium and calcium carbonates and barium silicate. A pair of cylindrical graphite anodes 10 are enclosed at the lead-in ends in refractory caps 11, and are separated by a nickel or like baffle 13. The anodes may taper slightly, with their larger ends towards the seal, to prevent screening of any part of the surface should they be slightly tilted during sealing-in. To secure maximum excitation of the fluorescent material, which occurs with radiations of the order of 1,200-3,100 A.U., the internal diameter of the tube is made approximately 1.1 inches. After a preliminary exhaustion and heating, the lamp is further heated to 530‹C. to drive moisture out of the walls, which are prevented from collapsing by admission of dried air or inert gas, the temperature being then reduced and the lamp again evacuated. The anodes and cathode are then degased by heating in a high-frequency field, the cathode being heated sufficiently to fuse the silicate and sinter the activating materials. The necessary quantity of mercury is then distilled into the tube and argon is admitted under a pressure of from 1 to 3 mm. of mercury.
