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).

Abstract: The invention relates to a method for determining the UV transmittance of water in a UV disinfection system through which water flows, wherein the UV disinfection system has a plurality of emitter assemblies (1) each comprising: a UV radiation source (2); a cladding tube (3) that surrounds the UV radiation source (2), which cladding tube has an end face (13) on one open end (12); and a UV-C sensor (6) which detects UV light emerging from the cladding tube (3) without the influence of the water. The UV disinfection system also has at least one further UV sensor (23), which is arranged at a distance from the cladding tubes (3) of the emitter assemblies (1), wherein the method has the following method steps: a) for at least one emitter assembly (1), measuring the UV radiant power emerging from the cladding tube (3) by means of the UV-C sensor (6); b) measuring a quantity of the transmitted radiant power by means of the at least one further UV sensor that is spaced apart from the UV radiation sources; c) determining the transmittance of the water by means of a quantity of the emerging radiant power and of the transmitted radiant power.
