Comparing to controller equipment in the market, this circuit has larger control ability. The circuit adopts RCA7163cadmium sulfide photocell. The sunlight shines on PC2. It canmake it stay on low resistance. So it is not enough to light up the neon light. PC1 and neon light are in the same shade, so it is dark. When darkness is colsed, PC2 is in high resistance topromote neon lightand light up it. The light of neon light shines on PC1. The PC1's resistance is decreased. It can control three ends ofbidirectional thyristor to turn on. Then the lamp inserted in S0L is lit.
