“…The detection method was based on lamp voltage amplitude variation. In [12], during the AR, low frequency ripples (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) are present in lamp current. The FFT method could be applied for AR measurement.…”

In the last decades, the high pressure sodium (HPS) lamp has been supplied in high frequency in order to increase the efficacy of the lamp/ballast system. However, at some given frequencies, standing acoustic waves, namely acoustic resonance (AR), might develop in the burner and cause lamp luminous fluctuation, extinction and destruction in the most serious case. Two main characteristics of the acoustic resonances in a 150W HPS lamp are presented in this paper and we seek for a control method to avoid the lamp AR. The first one is the characteristic of the lamp AR threshold power, and the second one is the differences between forward and backward frequency scanning effects. Both characteristics allow us to further understand the AR and to better control the lamp.Index Terms-Acoustic resonance, AR threshold power, AR detection, forward and backward frequency sweeping

“…Certain literatures deal with the effect of lamp tube and electrode shape on the acoustic resonance [4] [5]. Some physical models of lamp AR have also been developed to predict the eigenfrequencies [2] [6]. However, the AR power threshold is still determined experimentally.…”

In order to reduce the electric consumption for high intensity discharge lamps, the use of high frequencies electronic ballasts represents both a solution and many advantages such as the decrease in the congestion and low costs. However, high frequency operation is not regarded as perfectly reliable due to the appearance of acoustic resonances inside the arc tube, which can result in low frequency light flicker and even lamp destruction. Therefore a predictive model was established in order to give us at which frequencies light flicker can be expected. Moreover, we conducted an experimental study, which allows the electrical detection of frequency regions, in which the discharge arc behaves instable. Furthermore, an optical system is incorporated to record images of the discharge arc during stable and instable operating conditions. The results enable a considerably better understanding of the flicker phenomenon in HID lamps and facilitate the development of energy efficient drivers.
