Abstract
A gamma stimulation apparatus comprises a rectifier, a control module, a first modulation operation switch (MOS), a second MOS, and first and second light sources. The control module operates the first light source at a first operating frequency (OF1) via the first MOS, and the second light source at a second frequency (OF2) via the second MOS. The first and second light outputs superimpose each other to form a superimposed light having a superimposed frequency equal to OF2−OF1 and between 20 Hz and 45 Hz. For every fixed period of a recalibration cycle, the control module is configured to operate only one of the two light sources or operate two light sources at a same frequency.
