Abstract:
A low-pressure mercury discharge lamp is provided with a light-transmitting discharge vessel (10) which contains mercury and a rare gas and which comprises means (20) for maintaining an electric discharge in the discharge vessel. A metal holder (30) supporting an amalgam (31) is arranged in the discharge vessel. The holder (30) is a metal plate (33) bent about an axis (32), portions (34a, 34b) of the plate bent towards one another defining a slot (35), while the holder is pinched together at its ends (36) and the amalgam (31) coats the holder on an internal surface (37) thereof. The manufacture of the holder is simple.
