Abstract
The purpose of this work is to study the influence of the power supply frequency and the current waveform on the spectral radiant flux emitted by a germicidal UV lamp. These lamps are used in waste water treatment by UV irradiation. Three types of power supplies are then used, an electromagnetic ballast, an electronic ballast allowing modulating frequencies and a current inverter delivering rectangular signals at variable frequency. To evaluate energy emitted in the UV bandwidth, a photometric system composed by an integrating cylinder, a monochromator and a CCD camera is mounted.
