Abstract:
A amplitude dimming power supply for constant-voltage LED lamp group comprises a maximum current signal conversion module, a DAC module electrically connected with the maximum current signal conversion module, a dimming signal output module, a signal processing module electrically connected with the dimming signal output module and the DAC module, a lamp group current sampling module, and a comparison control input module. The present invention is directed to the constant-voltage LED lamp group amplitude dimming, the dimming current is based on constant-voltage LED lamp group real-time changes. Constant-voltage LED lamp group maximum dimming current determines the duty cycle and the amplitude of the PWM signal output by the maximum current signal conversion module, so that the maximum dimming current of the amplitude dimming power of the constant-voltage LED lamp group is always equal to the total current of the current LED lamp group. The amplitude dimming power supply can work in full scale range and the phenomenon of dead zone doesn't appear.
