The chart shows the simple light-operated street lamp circuit which is easy to make, as long as the advent of night, lamps will be automatically lit and turned off in the daytime. The circuit has a soft start function, when night falls, the natural light is gradually weak, so the photosensitive resistor RL is larger gradually, and VT gate level is gradually increased. Therefore, the on and off atate of thyristor is a stage of micro-conduction and conduction-weak, so the light E has a soft-start process of been gradually brighten.
