Abstract
507,650. Electric incandescent lamps. STRATEG STRAHLUNGSTECHNIK GES. Sept. 10, 1937, No. 24750. Void. Convention date, Sept. 10, 1,936. Drawings to Specification. [Class 39 (ii)] The bulb of a lamp containing a gas filling of krypton, xenon, or a mixture of these gases, is made as small as possible and surrounded by an outer bulb of the size usual in the case of ordinary lamps of the same wattage and, in order to neutralize the consequential increase in temperature, the space between the bulbs is filled with a gas or vapour, the heat conductivity of which is greater than that of air, suitable gases being helium and hydrogen. Alternatively the space may contain substances which give off heat-conducting vapours when tho lamp is in operation. The outer bulb may be frosted internally.
