Abstract

Offenbart ist eine Halogenglühlampe mit einem einseitig abgedichteten Lampengefäß, in dem zumindest ein Leuchtkörper aufgenommen ist, wobei ein Gefäßabschnitt 42 als Seitenreflektor ausgebildet ist, der sich nur über einen Teilbereich des Lampengefäßumfangs erstreckt. In Umfangsrichtung an diesen Gefäßabschnitt 42 schließt sich ein Lichtaustrittsfenster 42 an. Erfindungsgemäß ist das Lichtaustrittsfenster 40 im Querschnitt vergleichsweise gering gekrümmt ausgeführt, wobei der den Seitenreflektor ausbildende Gefäßabschnitt 42 sich vom Lichtaustrittsfenster 40 weg auswölbt. Vorzugsweise ist dieser ausgewölbte Bereich mit einer nierenförmigen Einschnürung 46 versehen.

Figure imgaf001
Disclosed is a halogen incandescent lamp with a lamp vessel sealed on one side, in which at least one luminous element is accommodated, wherein a vessel portion 42 is formed as a side reflector, which extends only over a partial region of the lamp vessel periphery. In the circumferential direction of this vessel portion 42, a light exit window 42 connects. According to the invention, the light exit window 40 has a comparatively slightly curved design in cross section, with the vessel section 42 forming the side reflector bulging away from the light exit window 40. Preferably, this bulged area is provided with a kidney-shaped constriction 46.
