it shown in Figure 2-35. When closing the switch SA, the lamp brightness from weak to strong light; open the switch SA, lamp brightness from strong to weak extinguished. Adjustment potentiometer RP, can change the bulb. Such as using the values shown in Figure 2-35, lights fade in, fade-out process of approximately 60s. Change Rs, horses, cl, and the resistance of RP, you can adjust the fade in, fade-out time. If you want to control the lamp power group, select high current rectifier diode and thyristor can be.
