Abstract: The invention relates to an ultraviolet mercury low-pressure amalgam lamp (2) comprising: a tube (3) having a first end (1) and a second end;
a first electrode (4) placed in the first end (1) of said tube (3);
a second electrode placed in the second end of said tube, whereby when the lamp (2) is energized a discharge path is formed between said first and second electrodes; and at least one amalgam deposit (6) adjacent to one of said first and second electrodes out of the discharge path between said first and second electrodes, wherein the tube (3) has at least one constriction (7) wherein the at least one amalgam deposit (6) is placed behind the constriction (7) with respect to the discharge path such that the at least one amalgam deposit (6) is protected by the constriction (7) from the heat emitted by the electrodes (4).
