Comparison of the Emission of a High-Pressure Sodium Lamp Working at 50 Hz and at High Frequency

A spectroscopic study of the behavior of a high-pressure sodium (Na) lamp is performed in this paper. The lamp works at 50 Hz and high frequencies. The study includes the analysis of the detected spectra from 400 to 700 nm, the determination of the lamp stabilization time, the Na vapor pressure, and the electronic excitation temperatures.
