Abstract

The invention describes a low-pressure mercury vapor discharge lamp and a method for the manufacture of such a lamp. The lamp offers a more compact design compared to existing lamps, and comprises a glass vessel enclosing a discharge space, provided with at least one glass stem located within an end portion of the glass vessel, bearing an electrode arranged within the discharge space, and a container encapsulating an amount of amalgam, provided with an opening enabling gas exchange of the amalgam with the discharge space.
