The aim of the work is the research of influence on light efficiency of photoluminophor of Zn2SiO4:Mn having pulse and average intensity of gas discharge ultra-violet radiation. The research was conducted at the time when pulses were insufficient for transition of photoluminophor to the saturation mode. It is established that the greatest light efficiency is reached at small pulse intensity of exaltation in the wide range of average intensity provided by the change of frequency and (or) duration of discharge pulses in a cell. It is shown that the decisive impact on light efficiency is exerted by the decrease of quantum output of photoluminophor on flash location at the expense of highlighting action of radiation. Recommendations about the choice of exaltation modes providing either greatest light efficiency, or largest brightness are given.

Key words: luminophor light efficiency, exaltation mode, quantum efficiency, pulse duration, saturation mode.
