Abstract:
An operating device for operating at least one Hg low-pressure discharge lamp which has a first and a second electrode coil may include a unit for providing a variable that is correlated with the Hg vapor pressure in the at least one Hg low-pressure discharge lamp comprises at least one unit for capturing emission spectra of at least specifiable spectral ranges, wherein the unit for capturing emission spectra may include at least one light receiving unit which is arranged in the beam path of the at least one Hg low-pressure discharge lamp.
