| Resum: | The paper presents the results of the study of energy and dynamic characteristics of white glow LEDs FYL-3014 and ARPL-1W when powered by U-shaped pulses. Based on the obtained oscillograms, it is established that the increase and decrease of the luminous flux is described by an exponential dependence, from which the constants of the relaxation time are determined. As the frequency of the pulsed power supply increases, the time constant of increase and decrease of the luminous flux decreases. Based on the analysis of the parameters of the light flux LEDs kinetics and its behavior with a change in the frequency of the pulse supply and the amplitude of the pulses, it is shown that one-component phosphor YAG:Ce is used. The most energetically favorable frequency range of pulsed power supply FYL-3014 and ARPL-1W of white glow is from 1 to 100 kHz. |
