LIGHTING DEVICE WITH OPTICAL PULSATION SUPPRESSION BY POLYPHASE-DRIVEN ELECTRIC ENERGY

The invention relates to the use of multi-phase driving electric energy to directly use the electric energy of the AC power source to drive the luminous body, and the pulsation rate of the luminous brightness with the AC power voltage can be reduced.
