One-dimensional model for a barrier discharge lamp is investigated. The plasma coefficients employed in the model were determined by the trial-and-error method. Using this model, fairly good agreements are obtained between the calculated discharge current waveforms and the measured those for several applied voltage waveforms. The distributions of electron density, ion density, and the electric field at each phase of the discharge cycle are obtained by this model. Then the mechanism of current-waveform formation is discussed. In the case of the applied voltage of sinusoidal, triangular, and trapezoid waveforms, the model shows that abrupt ionization in the space charge layer on the wall takes place during the current increasing phase. However, such ionization would not take place during the current decreasing phase. These results agree with the experimental results.
