CA 2653037
The lamp uses a sealing system with a ceramic supporting element (17) having a short length LA together with a W-Nb leadthrough part (18, 19, 20) and a specially adapted glass solder (21), which is based on an Al2O3 rare earth oxide system. In this case, the W part is accommodated in the supporting part over a length LW of 1 mm, and the aspect ratio LW/DUW, formed from the length LW and the diameter DUW of the W part, is at least 10.
