摘要

了解金属卤化物灯中声共振的发生是设计高频电子镇流器的必要条件。本文提出了一种用测量灯电压来代替人眼观察灯弧来检测声不稳定性的简单方法。灯电压的标准偏差被用作确定声共振发生的指标。有了这个指标，灯弧不稳定的程度可以很容易地指定。在不同型号的70 W灯上进行了实验，考察了灯型、使用时间和工作功率对声共振频谱的影响。

Detection of acoustic resonance in metal halide lamps

To understand the occurrence of acoustic resonance in metal halide lamps is essential for an engineer to design a high-frequency electronic ballast. This paper proposes a simple method by measuring the lamp voltage for detecting the acoustic instability instead of observing the lamp arc by human eyes. The standard deviation in the lamp voltage is used as an index to determine the occurrence of acoustic resonance. With the index, the degree of the lamp arc instability can easily be specified. Experiments are carried out on various 70 W lamps to inspect the influence of the lamp type, the used hours, and the operating power on the frequency spectra of acoustic resonance.
