Abstract
The present invention relates to an electrical incandescent lamp (), in particular a halogen incandescent lamp, in which luminous element limbs () extend in lamp vessel structural parts (), the lamp vessel structural parts surrounding the luminous element limbs in sections at a distance, and the axes of the lamp vessel structural parts () extending at a distance from one another in order to increase the energy efficiency of the incandescent lamp, in particular if a layer () 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.
