The basis for further improvements of metal halide lamps is an understanding of the physical processes in the discharge plasmas of these light sources. For this purpose the role of the different fill components in the development of the irradiation and the electrical parameters is investigated. This is achieved by considering the relevant physical processes in a model for the radiation transport, the temperature distribution and the electrical field strength of the discharge plasma. By comparisons with corresponding experimental data a view of the functional principle of the mercury-thallium-thulium-iodine-argon high pressure discharge is developed.
