A stationary model for a spark light source at high current densities and gas pressures is developed. The model assumes that the plasma is in local thermodynamic equilibrium and radiates like a blackbody. The equations employed are the energy balance equation and the circuit equation. The energy balance includes ohmic heating, radiation loss, loss to the boundaries, and ionization. The maximum temperature (radiance) of the source is calculated as a function of gas pressure and initial voltage. A good agreement is found with the previously published experimental results of the nanolight discharge light source. This model is general and can be extended to any high pressure discharge which can be considered stationary.
建立了一种适用于高电流密度和气体压力下火花光源的稳态模型。该模型假设等离子体处于局部热力学平衡状态，并像黑体一样辐射。所采用的方程是能量平衡方程和电路方程。能量平衡包括欧姆加热、辐射损失、边界损失和电离。计算了光源的最高温度（辐射率）作为气体压力和初始电压的函数。与先前发表的纳米光放电光源的实验结果取得了良好的一致性。该模型具有通用性，可扩展到任何可视为稳态的高压放电。
