摘要

The system has power supply lines (2, 4) sectionally formed from hollow tubes e.g. carbon nanotube, and arranged in an axial direction of a lamp vessel (6). The lamp vessel electrically contacts a spiral-wound filament (8). The power supply lines are guided through a compressible seal (12) from the lamp vessel. A photoresist section (10) is arranged on an upper end of the lamp vessel. The compressible seal is provided in a lower end of the lamp vessel for sealing an inner space (14). The lamp vessel is formed from a hard glass or a quartz glass.
