摘　　要：为了研究提高无极灯光效的途径,本文通过测量无极灯的放电电压、电流、功率和光照度,计算了无极灯的阻抗变化。结果表明,放电电压先降后升而后趋于稳定;放电电流先升后降然后趋于稳定;无极灯阻抗先迅速下降而后小幅升高再趋于稳定;光照度先升后降而后趋于稳定。迅速稳定无极灯泡体内的等离子体浓度才能提高无极灯的稳定性。In order to obtain the methods for improving the efficacy of electrodeless, the paper measured discharge voltage, current, power and illuminance of electrodeless lamp, and calculated the discharge impedance. The results show that discharge voltage firstly increases then decreases to be stable, discharge current drops firstly then rise to be stable, lamp impedance first lowers quickly then increases to be stable, and illuminance firstly increases then lower to be stable. Electrodeless lamp can be stabilized quickly by improving electron density of discharge plasma.
