“…Another method referred to as 'spread spectrum' is also reported to reduce lamp instabilities when operated at high frequencies [6]. Lamp AR experimental characterizations are also conducted so as to define AR zones and its detections necessary for ballast design [7][8][9]. In [10] a model of HID lamp including the acoustic instabilities has been performed.…”

International audienceThis paper presents a numerical model of High Pressure Sodium (HPS) lamps including the acoustic streaming. The model is implemented in COMSOL and based on the finite elements method using a 2D axi-symmetric geometry. Moreover, a revision concerning AR experimental characterizations of HPS lamps will also be provided. The results presented in this paper will contribute to the understanding of AR phenomena and help in the electronic ballast design methods for AR avoidance

“…Over the past years an enormous effort has been made to investigate and avoid the phenomenon of acoustic resonances in HID lamps. In [2,3,4] the frequency dependent fluctuation in light intensity is measured by broadband photodiodes for lamps of different geometries. In [5] lamp geometry and operating frequency schemes are used to reduce the negative effect of acoustic resonances.…”
