ABSTRACT:
The present invention relates to an electrical incandescent lamp (1), in particular a halogen incandescent lamp, in which luminous element limbs (14, 16) extend in lamp vessel structural parts (42, 44), the lamp vessel structural parts surrounding the luminous element limbs in sections at a distance, and the axes of the lamp vessel structural parts (42, 44) extending at a distance from one another in order to increase the energy efficiency of the incandescent lamp, in particular if a layer (42a,44a) which reflects IR radiation is applied to the lamp vessel structural parts. When using the pinch-sealing technology, it is possible to achieve a small system voltage halogen lamp having a long life expectancy and at the same time requiring little energy for reaching the operating temperature.
