Halogen filament lamp, has filament with outlet that is enclosed by molybdenum foil, where ends of foil are arranged without overlapping, such that foil is used as welding aid for welding connection between filament and power supply line

摘要

The lamp has a spiral-wound filament (3) with a spiral-wound outlet (31) that is enclosed by a molybdenum foil (8) over a circumference angle within a range of 180 degrees up to 360 degrees. Ends of the molybdenum foil are arranged without overlapping, such that the molybdenum foil is used as welding aid for a welding connection between the filament and a power supply line (5). The power supply line is connected with the spiral-wound outlet of the filament, where the power supply line is made of molybdenum or molybdenum alloy.
