Description

Illuminating device for suppressing light pulsation by multi-phase driving electric energy

The present invention relates to the use of multi-phase driving electric energy to drive the illuminant directly by using the electric power of the alternating current power source, and the pulsation rate of the illuminating luminance with the alternating current power supply voltage can be reduced.
