As shown in the figure, this circuit can automatically adjust the light brightness according to the intensity of external light. If the outside brightness is high, the light will be dark; if the outside brightness is low, the light will be bright. In the figure, a full-wave phase control circuit is composed of thyristor VT1 and diodes VD1~VD4, and neon tube N is used as the trigger tube of VT1. Adjusting W can change the charging time constant of capacitor C, that is, change the conduction angle of VT1 and control the brightness of the light.
