PULSATION OF LUMINOUS FLUX OF LIGHT EMITTING DIODES AND FEATURES OF THEIR MEASUREMENT AND RATIONING
PULSATION OF LUMINOUS FLUX OF LIGHT EMITTING DIODES AND FEATURES OF THEIR MEASUREMENT AND RATIONING
Some features of luminous flux pulsation of light emitting diodes caused by their characteristics and by their power supply devices are considered in this article. It is shown that the pulsation of radiation of luminaires with light emitting diodes and with gas-discharge lamps can differ essentially from each other by its intensity, waveform and frequency. Therefore, it is concluded that the luminous flux pulsation measurement methods accepted today and their standards developed in the middle of the twentieth century for gas-discharge illumination, in some cases cannot be used for light-emitting diode illumination and should be revised.
