The digital dimming technology takes full advantage of two kinds of technologies:one is altering the way of the current through the LED light source and the other is PWM dimming technology.By integrating them,it uses CAN bus to transfer the dimming signal.As an ideal method,the digital dimming technology is beneficial to reduce the amount of cables and consequently gain the weight saving. Besides,the EMI due to the long range transmission can be avoided.
