Abstract
An electric incandescent lamp has a filament having two incandescent portions interconnected by an intermediate non-lightemitting conductor. The filament is accommodated in a single ended, pinchsealed tubular glass envelope and is supported therein in that the intermediate conductor is embedded in an inner portion of a second pinch seal. The lamp has means to lower the temperature of the intermediate conductor and thereby of the second pinch, if the maximum permissible temperature of the latter would otherwise be exceeded.
