• This paper proposes a statistical method for modeling the voltage versus current characteristics of a fluorescent lamp. Parameters of the model are selected from various parameters by applying a maximum R^2 improvement method to keep generality of the model. The voltage-current characteristic of the fluorescent lamp is expressed by an equivalent resistance as a function of instantaneous lamp power and its differential coefficient. Therefore, the fluorescent lamp is modeled without knowing physical constants such as the electron impact excitation cross sections of mercury atoms. The simplicity of the equivalent resistance of the fluorescent lamp reduces instability and the computation time required for an analysis of the lamp circuit.Numerical simulations under various conditions are performed using Electromagnetic Transient Program (EMTP). Results calculated for various applied voltages ranging from 50 Hz to 100 kHz agree well with experimental results. The proposed model is confirmed to be independent of voltage waveform and also to be applicable to various types of lighting circuits such as an inductive ballast and an electronic ballast.The stable characteristic of the proposed model opens a way of a computer aided design of a lighting equipment.
