| Abstract: | Recently,multi-channel lighting is widely used,but each LED is equipped with a separate driver's source.The method investigated to be able to control multi-channel LED is that the computer send the dimmer signal to MCU,and use CD4067 to realize multi-choice,MCU produce PWM to adjust the value of current in the dimmering circuit.Dimmer circuit uses two methods,one is adopted working current mode,and the other is pulse width modulation mode.Through the experimental study,expounds the principle of the multi-ch... |
