Automatic light control one lamp lighting circuit b

Automatic light control circuit lights automatically illuminate the lamp when dark, lights automatically turn off when daybreak. (1) One of the automatic light control circuit

lighting circuit 286 shown in FIG. Both circuits are bidirectional thyristor tube, the circuit is simple. For Figure 2-86 (a). If the photoresistor RG no light when light is off, the capacitor C should be increased capacity. Inadequacies of the circuit in the sense that before each automatic lights on or off flicker. For Figure 2-86 (b), adjustment potentiometer RP, can change the brightness of the light. The circuit can be used as night light use.
