ABSTRACT:
A low-pressure mercury vapor discharge lamp is provided with a discharge vessel which encloses a discharge space including a filling of mercury and a rare gas in a gastight manner. The discharge vessel further includes an amalgam which communicates with the discharge space. The lamp has a discharge device for maintaining an electric discharge in the discharge vessel. The amalgam includes a bismuth-tin-indium compound having a bismuth (Bi) content in the range between 30≦Bi≦70 wt. %, a tin (Sn) content in the range between 25≦Sn≦67 wt. %, and an indium (In) content in the range between 3≦In ≦5 wt. %.
