LED Driver Circuit Explained | How LED Chip Works & Why It Fails | Video Tutorial.

How are you all? I hope everyone is well and healthy by the grace of God. Today I will share with you how LED lights are powered through series lines.

Those of us who light LED lights in our homes and factories and on the streets at different places, they are powered through series lines. We know that series lines are connected to each other, and if we are 10 people in one place and put one hand with the other, and if we bring them to one place in a round way, then it works like a series line. So today we will see directly how series lines work and show the diagram, so let's start.

Here you can see first that I have gone to a diagram. Here 220 volts AC input voltage is given, and an LED driver circuit is given which is giving DC output, and above you can see that a diagram has been made with 20 LED lights, and they are connected to each other like a series line.

Now you can see an LED driver circuit; it is basically used to generate DC voltage to run the LED lights. LED lights will never run without DC voltage because LED lights are powered by parallel current.

Now you can see an LED chip; there are 20 LED chips here. And the LEDs are powered through a series line; one is connected to the other. If one LED chip is damaged, the entire 19 LED chips will stop working, so we will see that through the diagram.

Now you can see the positive and negative connections from the driver's power supply to the LED chip as shown in the diagram. Here, in reality, I have soldered the driver to the LED chip.

Now, I have taken 220 volts AC input voltage as shown in the previous diagram, and the driver circuit will output DC from 220 volts, and the LED chip will light up.

Now you can see that after the 220-volt input voltage goes through, my LED checks are lighting up and the light is reflecting from here.

Now, to better explain why the LEDs in the series line get damaged, I have damaged one LED from here, which you can see from the bottom of the LED chip.

Now I have given 220-volt AC input voltage, but my LED chip is not running because from here I have damaged one LED chip, and the circuit is providing voltage properly, which you can see DC output on the digital multimeter.

Now I have made a jumper here again with the soldering iron. Now the connection is made with the LED again, but one LED has been cut from the middle, but the connection is made with the remaining 19 LEDs. Now they are ready to run again. This can be seen clearly in the video. Hope you watch the video.
