String LEDs are now very popular as decorative lights which are available in different colors at very low cost. It gives very brilliant colour display sequencing in four channels. The blinking pattern is controlled by a programmed chip and the switching is achieved by a high volt SCR .String LEDs show automatic Multi pattern changing display. Its working is really amazing and breaking all the conventional circuit designs. It shows that how a chasing and blinking light pattern can be created using a very simple method. Thanks to China technology for giving such a simple and low cost decoration. Let’s open the tiny circuit box and see what is inside.
How it works
