Abstract:

This publication is devoted to the study of the spectral and light characteristics of pulsed discharges in sodium, potassium, rubidium and caesium vapours, as well as in mixtures of sodium with rubidium and caesium. The directions of increasing the luminous efficacy and colour rendering index were analysed theoretically. It has been experimentally established that the highest light output is provided by a discharge in vapours of pure caesium and its mixture with sodium. The spectral distributions of the radiation of the investigated discharges are presented and the justification for the presence of some narrow lines in the spectrum is made.
