Abstract

The subject of this paper is the modeling of optically thin radiation emitted by high-intensity discharge lamps filled with mercury. This is achieved by establishing a nonlinear differential equation for the radiance of optically thin mercury lines under local thermodynamic equilibrium assumptions in the case of a channel model. Modeling results in a 0.4-MPa mercury discharge fed by sinusoidal and pulsed current are presented and compared with the experimental results. The comparison results confirm the fair agreement between theory and experiment.
