Lighting method for pulsed triggering of lighting devices/LEDs splits a period into multiple time blocks of different duration firmly arranged as to time within the period

摘要

Lighting devices each switch on/off according to the status of each desired pulse-duty factor's bit associated by its significance. Each block of time is set up twice or more within each period (P) and symmetrically around the middle within each period. The duration of blocks of time steadily decreases from the beginning of the period towards its middle and increases from the middle to the end.
