Dual time constant bidirectional thyristor dimming light circuit

In order to solve the lag and light jump phenomena mentioned in the previous circuit ,
the dual time constant galvanic thyristor dimming
lamp switch shown in Figure 3d can be used. In this circuit, R is added. ,
C. Resistor-capacitor network, capacitor C. The reduced charge can be replenished
through the c^, R, and R circuits
, thus effectively reducing lag and light
jump phenomena, while also expanding the eight-knot range of the minimum brightness of the light .
