Patent ID: 7747891

Claim:
An inverter control circuit, which is used to control a switch and a transformer in front of a light-emitting unit and then adjust the driving power for said light-emitting unit and modify the luminant state of said light-emitting unit, comprising: a first control unit and a second control unit, both having equivalent electronic elements, wherein either of said first control unit and said second control unit have a signal generator and a signal synthesizer circuit; according to a signal fed back by said light-emitting unit and a dimming signal, said signal generator of said first control unit outputs first working signals via said signal synthesizer circuit of said first control unit to determine the turn-on time of said switch; according to said first working signals and via said signal synthesizer circuit of said second control unit, said second signal generator of said second control unit outputs second working signals to said switch to determine the resonance frequency of said transformer.
