Gas discharge tube including a starting aid

1. A gas discharge tube comprising a starting aid, comprising:

a discharge vessel with at least one open end, in which end a stopper with a continuous stopper bore is inserted; and

an electrical leadthrough, which is inserted into the respective stopper bore and is fuse-sealed into the stopper bore;

wherein the starting aid extends at least into the stopper bore,

wherein the starting aid has at least one starting strip applied to the outside of the discharge vessel and, on one side, a connecting part of the starting aid is formed from the starting strip at least into the stopper bore,

wherein connecting part widens and runs over a protruding rim of the discharge vessel.

2. The gas discharge tube of claim 1 , wherein the starting aid has a first region, which runs in the form of a ring sector around the stopper bore on an outer end face of the stopper, which first region is adjoined by at least one second region located in the stopper bore.

3. The gas discharge tube of claim 2 , wherein the first region covers the full area of the outer end face of the stopper.

4. The gas discharge tube of claim 1 , wherein the starting aid extends in the form of a tube into the stopper bore.

5. The gas discharge tube of claim 1 , wherein the starting aid extends over the entire length of the stopper bore.

6. The gas discharge tube of claim 1 , wherein the starting aid extends over no more than 50% of a length of the stopper bore.

7. The gas discharge tube of claim 6 , wherein the starting aid extends over no more than 25% of a length of the stopper bore.

8. The gas discharge tube of claim 7 , wherein the starting aid extends over no more than 10% of a length of the stopper bore.

9. The gas discharge tube of claim 8 , wherein the starting aid has at least one starting strip applied to the outside of the discharge vessel and, on one side, a connecting part of the starting aid is formed from the starting strip as far as into the stopper bore; wherein the connecting part has a thickness with a value in the range of from one to thirty micrometers.

10. The gas discharge tube of claim 9 , wherein the connecting part has a thickness with a value in the range of from five to fifteen micrometers.

11. The gas discharge tube of claim 10 , wherein the connecting part has a thickness with a value in the range of from eight to twelve micrometers.

12. The gas discharge tube of claim 1 , wherein the starting aid extends into the stopper bore by no more than 0.5 mm.

13. The gas discharge tube of claim 12 , wherein the starting aid extends into the stopper bore by no more than 0.3 mm.

14. The gas discharge tube of claim 1 , wherein a thickness of the starting aid in the stopper bore is between one and thirty micrometers.

15. The gas discharge tube of claim 14 , wherein the thickness of the starting aid in the stopper bore is between ten and fifteen micrometers.

16. The gas discharge tube of claim 15 , wherein the thickness of the starting aid in the stopper bore is twelve micrometers.

17. A gas discharge lamp, comprising: at least one gas discharge tube comprising a starting aid, comprising: a discharge vessel with at least one open end, in which end a stopper with a continuous stopper bore is inserted; and

an electrical leadthrough, which is inserted into the respective stopper bore and is fuse-sealed into the stopper bore; wherein the starting aid extends at least into the stopper bore,

wherein the starting aid has at least one starting strip applied to the outside of the discharge vessel and, on one side, a connecting part of the starting aid is formed from the starting strip at least into the stopper bore,

wherein connecting part widens and runs over a protruding rim of the discharge vessel.
