    摘要: To eliminate a holding frame for a starting wire (20) outside of an elongd discharge vessel (1), the starting wire (20) is directly connected to one of the electrode leads (4, 5), typically niobium tubes, by a bimetal strip (21) which is, preferably, bent in stepped form or Z shape. Under cold conditions, the strip or wire (20) is in engagement with the outside of the discharge vessel (1) to assist in starting, due to its electrical connection via the bimetal strip (21) with one of the electrodes; upon heating of the lamp, the bimetal strip (21) will lift the wire (20) off engagement with the discharge vessel (1) and thus prevent deterioration thereof.
