Abstract

957,921. Electric discharge lamps. GENERAL ELECTRIC CO. Nov. 24, 1961 [Dec. 27, 1960], No. 42095/61. Heading H1D. [Also in Division F4] An illuminating device comprises an enclosure having a transparent wall and means for holding in the enclosure a lamp containing a vaporizable substance, the temperature of the lamp being controlled by a heat-conducting device which extends from the interior of the lamp to the exterior, and is so arranged that its inner end contacts for heat conduction a restricted area of the lamp and its projection extending outside of the enclosure serves for heat dissipation. In one form, a part 5 of a lamp 3 is contacted by a tubular container 4 which extends upwardly to the outside of the enclosure 1 and which contains a vaporizable liquid and a non-condensable gas, and in operation, the liquid is co-operated, the vapour condensed in a copper condenser 9 and the liquid returned to the lower part of the device. Alternatively, two hollow tubes may be used, one inside the other, and the vapour forced up the inside of the smaller tube to be condensed on a heat-dissipating surface preferably cooled with cooling fins, and the condensed liquid returned between the two tubes. In either case, the outside tube may be lagged with material 20, and a heat-conducting grease used between the lamp and the heat-conducting device. Specifications 472,307 and 821,321 are referred to.
