FIELD: electric engineering. SUBSTANCE: device has torch which is made from transparent material, contains sealed electrodes and is filled with noble gas, lithium and halides of inactive metal. According to invention torch contains tin. Lithium and tin are contained in torch as alloy which contains 20-80 per cents of lithium. Composition content is mercury - 0.1 -8.0 dopes which supply torch with halides of scandium - 0.09-6.0 potassium - 0.3 -8.0 nickel - 0.02-3.0, in micro moles per cubic centimeter. Pressure of noble gas is in range of 1.33 - 2000.0 kPa. In addition device has dopes which supply torch with halides of illuminating metals in amount of 0.03 - 24.0 micro moles per cubic centimeter. EFFECT: increased during service life. |
