摘　　要：无极灯作为新型光源在日常中逐步替代传统有极灯而得到大量应用,但是无极灯的工作原理和效率还有待研究和提高。建立了具有氩/汞化学性质的二维模型无极灯,以模拟泡体内的氩/汞化学反应和物理放电过程为基础,在数值模拟中模拟泡体内化学反应情况,结合等离子体动力学,以及电场、磁场等多物理场的耦合计算,得到泡体内电子温度、电子密度、电阻损耗、等离子体电位和汞离子数密度之间对无极灯光效的影响。基于对不同激发态Hg原子的浓度对光效影响强弱的对比分析,得到63P1态汞原子的浓度高低是影响无极灯光效的主要因素。As a new type of light source,the electrodeless lamp gradually replaces the traditional electrode lamp and is widely used,but the working principle and efficiency of the electrodeless lamp need to be studied and improved. A two-dimensional model of electrodeless lamp with argon/mercury chemistry is established. Based on the simulation of the argon/mercury chemical reaction and physical discharge process in the bulb,the chemical reaction in the bulb is simulated in the numerical simulation,combined with the plasma dynamics,as well as the coupling calculation of electric fields,magnetic fields and other multi-physics fields,the influence of electron temperature,electron density,resistance loss,plasma potential and mercury ion number density on the electrodeless light efficiency in the bubble is obtained. It is found that the concentration of 63P1 mercury atoms is the main factor affecting the electrodeless light efficiency based on the comparative analysis of the effect of the concentration of Hg atoms in different excited states on the light efficiency.
