The figure shows the 3 different ways of driving high-power control circuit. Flashing light-emitting diodes can be used as high-power multi-center load control circuit devices to drive a variety of incandescent light flashes. Figure (a) uses high-power transistor to drive circuit; Figure (b) uses high-power bidirectional thyristor to controll driver circuit; Figure (C) uses relay to control the load. VT can choose 3AD, 3CD PNP power transistor. SCR can also use one-way, but the load current is pulsating DC current. The load of the 3 circuits flashes intermittently under the control of light-emitting diode.
