Abstract: Carrier element on which an Hg-containing material for application in a discharge lamp is formed, and discharge lamp with such a carrier element The invention relates to a carrier element on which an Hg-containing material for application in a discharge lamp (1) is formed, the Hg-containing material being in the form of a bar-shaped element (12) and being arranged on a holder (14, 15, 16, 17; 19) of the carrier element (11). The invention also relates to a discharge lamp of such a carrier element.

Abstract: A carrier element, on which an Hg-containing material for application in a discharge lamp (1) is formed, has at least one depression (12, 20 to 23), in which the Hg-containing material (17) is arranged. A method for producing such a carrier element and to a discharge lamp with such a carrier element is also disclosed.

Abstract: The lifetime of cold-start fluorescent lamps is increased, and the ability to withstand repeated ON-OFF switching cycles enhanced by coating the electrodes with an emitter which consists of barium oxide and a small portion of metallic barium and, optionally, up to 20 mol-% of strontium oxide and a small portion of metallic strontium, preferably only up to about 5 mol-% of strontium oxide--metallic strontium. To make the emitter, barium carbonate, optionally mixed with strontium carbonate, is applied in paste form to the electrodes which, when coated, are introduced into an envelope and sealed therein. The envelope is then evacuated, and the electrodes are heated,thus converting the barium carbonate to barium oxide and metallic barium, and the strontium carbonate, if present, to strontium oxide and metallic strontium, so that the electrodes will be coated with barium oxide, optionally strontium oxide, and metallic barium and optionally metallic strontium.
