Short-arc lamps are equipped with tungsten electrodes due to their ability to withstand a
high thermal load during operation. Nominal currents of more than one hundred amperes …

The purpose of this paper is to study the dynamic of a metal halide thallium iodine discharge
lamp fed by a sinusoidal and square power supply. For this, a chemical model under Local …

The accumulation of insulator surface contamination is closely related to the distribution of
flow field around the insulator. In order to study the unevenness of the insulator surface …

Operating high-intensity discharge lamps in the high frequency range (20-300 kHz) provides
energy-saving and cost reduction potentials. However, commercially available lamp drivers …

For energy efficiency and material cost reduction it is preferred to drive high-intensity
discharge lamps at frequencies of approximately 300 kHz. However, operating lamps at …

This paper presents investigation of methods for reducing light pulsation and plasma
temperature inside a high intensity discharge (HID) lamp arc tube. Differences found in light …

This article presents research of temperature distribution inside discharge lamps arc tubes
powered by different frequencies of electric energy at the same power. In presented …

To detect acoustic resonance (AR) in metal halide (MH) lamps, a simple high-sensitivity
method with a multiplier detector is presented in this paper. Voltage envelope variations are …

This paper presents a modeling of the lamp voltage with acoustic resonance in metal halide
lamps. The modeling is implemented in PSIM based on the signal with amplitude …
