Abstract (englisch):
Abstract: In this paper, an efficient inductively coupled medium pressure source for ultraviolet
radiation (UV-source) is demonstrated. The lamp was operated with powers up to 3kW while the
radiation and the coldest point temperature were measured. In addition, different coil geometries
were investigated. Here a symmetrical and asymmetrical winding density were compared. Also the
operation pressures and DC to radiation efficiencies are presented. In this work, an operation pressure
of one atmosphere and an UV-efficiency (200–380 nm) of 15.5% was achieved. This is comparable to
conventional medium pressure Hg-lamp technology. The main advantage of the presented inductive
lamp is the electrodeless operation and therefore the longer service life, since an electrode failure
is eliminated.
