Flicker coefficient

WebSep 1, 2024 · Flicker index is an optical parameter used to describe the light intensity fluctuation of LED lamps. However, in probability theory and statistics, coefficient of variation is a standardized measure of data dispersion. In fact, the coefficient of variation can also reflect the fluctuation degree of light intensity waveform of LED lamps.
