摘要

电流脉冲馈电HPS灯即使灯的工频没有激发弧管内的纵向声共振模式，也会产生可听的噪声。这种噪音是由电弧管支撑框架的导电部分和通过外部玻璃外壳密封的导线的磁致伸缩引起的。导体尺寸的变化有效地将机械能耦合到护套上。光声效应还会由于灯周围薄空气层中的压力波而引起噪声。本文对这两种现象进行了实验研究，并量化了它们的贡献，以尽量减少声发射。

Sound emissions from pulse operated high-pressure-sodium lamps

Current pulse fed HPS lamps generates audible noise even if the lamp power frequency does not excite longitudinal acoustic resonance modes inside the arc tube. This noise is caused by magnetostriction in conductive parts of the arc tube-supporting frame and in the wires passing through the seal of the outer glass envelope. Conductor dimensional changes effectively couple mechanical energy to the jacket. Photoacoustic effects also cause noise due to pressure waves in a thin air layer surrounding the lamp. This paper investigates experimentally both phenomena and quantifies their contribution in order to minimize acoustic emissions.
