A dynamic collisional-radiative model of a low-pressure mercury (Hg)-argon (Ar) discharge lamp for application in circuit simulations is presented. The model is implemented in MATLAB as a set of coupled rate equations that are solved simultaneously to give the electron density, the density of the 63P0,1,2states and the electron temperature. These parameters are used to compute the electrical parameters of the discharge positive column and hence the time-dependent voltage-current characteristics of the lamp. The parameters predicted by the model are compared with published experimental data and show good agreement. Calculated lamp voltage-current characteristics based on the model are shown to be in good agreement with direct measurements on commercial fluorescent lamps.
