Lighting flicker, a rapid and repeated change over time in the brightness of light, has long been known to cause illness in humans that ranges from headaches to seizures. Thus, [1] has specified the dimming frequency, fDIM, larger than 3kHz to achieve a no-observable-effect flicker level. State-of-the-art LED drivers employ the SIMO topology with four channels in Fig. 12.7.1, to deliver energy to each LED using the time-multiplexing (TM) control technique [2-4], in which the luminance is… CONTINUE READING
