LED light mixing method

The invention provides an LED light mixing method. According to the method, first pulse waveforms corresponding to pulse opening time of more than two LEDs participating in light mixing are sequentially arranged; the arranged pulse waveforms are divided to obtain second pulse waveforms according to a pulse period T; the second pulse waveforms are output in parallel within one pulse period T; the originally superposed pulses are sequentially arranged in a manner of lowering the stroboscopic rate; the superposed pulses are divided into a plurality of pulse segments according to the period T; and the plurality of pulse segments are continuously and repeatedly arranged within one period T, so that the stroboscopic rate during light mixing of a plurality of pulses is lowered; and the stroboscopic phenomenon of a light source is reduced.
