Abstract	The radiative characteristics of high-frequency electrodeless lamps in a mixture of mercury and argon have been studied theoretically and experimentally as functions of the cold spot temperature (the pressure of mercury vapor). The intensity of the mercury lines at 404.7, 435.8, and 546.1 nm, corresponding to the triplet transition (7$^{3}$ S $_{1}$-6$^{3}$ P $_{0,1,2}$) in the visible spectral region, as well as the intensity of the UV resonance line (6$^{3}$ P $_{1}$-6$^{1}$ S $_{0}$) at 253.7 nm, has been measured. A model describing the physical processes in the discharge plasma and including the kinetics of excited states of mercury and argon atoms has been suggested. The parameters of the discharge plasma and the electromagnetic field have been calculated self-consistently through the numerical solution of the system of equations of electron density and energy balance and population balance of excited levels of argon and mercury atoms, as well as the Maxwell equations. The model developed has allowed us to calculate the intensities of the mercury emission lines at 253.7, 404.7, 435.8, and 546.1 nm and to compare the results with experimental data. The relative intensities of the mercury spectral lines corresponding to the triplet transition 7$^{3}$ S $_{1}$-6$^{3}$ P $_{0,1,2}$ have been calculated for the first time on the basis of a self-consistent model of the discharge.
