Abstract
A carry-signal controlled LED light with fast discharge includes at least one LED and a drive unit. The drive unit includes a signal detector, a fast discharge unit, a light control unit, and a capacitor. The signal detector receives the carry light signal and provides a discharging control signal according to the carry light signal. The fast discharge unit receives the discharging control signal and controls a voltage of the carry light signal to be fast lower than a low-level voltage. The light control unit drives the light behavior of the at least one LED according to light command content of the carry light signal. The capacitor receives a DC power source to be charged and provides the required work power to the LED light when the fast discharge unit fast discharges.
