ABSTRACT:
Disclosed is a halogen incandescent lamp having a lamp vessel, which is sealed at one end and in which at least one luminous element is accommodated, a vessel section42being in the form of a side reflector which extends only over a subregion of the lamp vessel circumference. A light-exit window40adjoins this vessel section42in the circumferential direction. According to the invention, the light-exit window40is comparatively slightly curved in cross section, the vessel section42forming the side reflector bulging out away from the light-exit window40. This bulged-out region is preferably provided with a kidney-shaped constriction46.
